For the full functioning of the disk with Advanced Format technology under WinXP, it is necessary to check it - these are the official recommendations and test results. For XP, the utilities are available on the WD website. Vista / 7/2008 Server also has no problems - Advanced Format is supported by them out of the box. What is the point of Win2003 - there is no official information about the choice of discs from AF, no WD, no MS. What's more, the distribution alignment tool (WD Align) is available in Win2003.

By the method of this small investigation, it was experimentally confirmed the need to verify the partitioning of a disk with Advanced Format technology, which is a functional Windows Server and so on Under the cat trohi of theory, practice, vysnovki and instructions.

1. Theory

1.1. advanced format

WD Advanced Format technology is used in most of the so-called "long sectors" with a size of 4Kb on the physical disk level. That hour has a traditional sector expansion - 512 bytes. Modern operating systems can work with 4Kb sectors, but WinXP and Win2003 don't have to. For a good trick, WD cunningly created hardware emulation: “in the middle” of the disk, information is stored in 4Kb sectors, and the “calls” of the OS work with it through 512-byte sectors.
You can read in detail about the technology, for example, or. Well, I will present a small vizhimki.

The first problem of such an emulation is that once a 512-byte sector is written to a disk, the disk must read a 4Kb sector, change a 512-byte sector, remap ECC, and write the 4Kb sector changes back. But the problem goes to another plan when formatting a disk in WinXP / Win2003 - in this case, the cob does not expand between physical 4Kb sectors. Through tsyu osoblivіst formatuvannya creations rozdіl vyyavlyayutsya rush to one 512-byte sector.

As a result, when the operating system is powered up, the disk in some cases can be processed not with one physical 4Kb sector, but with two external ones. This, obviously, reduces productivity.

To solve this problem, WD proposes to carry out a sector review in a division along the boundaries of physical sectors. For whom, two solutions are proposed: hardware and software. The hardware decision is based on the jumper setting 7-8 on the hard drive. To virіvnyati distributed programmatically under the global access was added a utility under the name WD Align.

In hardware variance, WD does not guarantee normal work when splitting the disk into a sprat (> 1) splitting. In addition, the hardware solution (jumper) is not visible either in the utility or in the operating system. And so, theoretically, you can turn off the jumper, and then carry out the virtualization programmatically (or create a split in the current OS) - and as a result, remove the "underwhelming" damage.
For these reasons, the software will be reviewed (but the hardware will also be tested).

1.2. WD Align and Windows Server 2003

For the most important functions for software sector scanning, WD uses two utilities: Paragon and Acronis. The version like Paragon can be installed on Win2003 (and її, to the point, in Supported Operating Systems honestly not). Version like Acronis in Win2003 is installed, but when you change the disk, it shows as "Not a disk format western digital Advanced Format ", and the split is like" Not optimally parsed. It is impossible to check the distribution of the utility in this situation.

There are no official announcements about the support of Advanced Format technology in Windows Server 2003, about the WD Align stoppage - tezh. For theory - in Win2003 the same core as in WinXP. And that means that the stench of the discs is due to pratsyuvati (mayzhe?) However. In order to reconsider the “mayzhe”, productivity tests were carried out.

2. Practice

Let me tell you right away: the test method did not measure the maximum code of disk i, moreover, it was not equal to other disks or other tests. The method of these tests was to reveal the difference in the speed of the work of the disk with checked and unchecked partitions.

As a sample of tested WD20EARS with a volume of 2TB, as a sample of testing - Iometer 2006.07.27. Before the program, it is possible to finish reports. Russian with a description of the main improvements can be recognized, for example.
There were conducted anonymous tests with different access specifications, including the following variations:
- Read / Write - reading / writing
- Sequential / Random
- Transfer Request Size - different rozmіr blocks when converting to disk (512 / 2k / 4k / 16k / 64k)
- Outstanding I / Os - number of one-hour drinks to drive (1/4/16/64/256)

For the sake of complete impersonality, I cite the results, which, if necessary and sufficient, can show - what is the difference between viable and non-violent divisions. Access specification parameters are as follows:
- Read / Write: 50% / 50%
- Sequential / Random: 100% Sequential
- Transfer Request Size: 512 / 2k / 4k / 16k / 64k
- Outstanding I/Os: 1
With whom, the disk was tested in the following formatting options:
1. unvirtivated unmapped disk. unallocated.
2. Unchecked disk space. unaligned.
3. Virіvnyany (jumper) rozmіcheny disk. Aligned (hard).
4. Align (WD Align) the disk. Aligned (soft).
To reduce the influx of fallout factors on the tested system, all “necessary” services were turned on and the measure was turned on.
The skin access specification was tested by stretching 5 minutes with a Ramp Up Time of 15 seconds.

The test results are as follows:

Verdict: Virus distribution on disks with Advanced Format under Windows Server 2003 is necessary, which follows from the theory. Of course, the disc with non-virivnyan splits will be pratsyuvati, ale shvidkodiya with this kulga.

3. Instructions for vigilance

As already mentioned in the theoretical part, the WD Align utility under Win2003 is not visible. To that happen to carry out a vir_vnyuvannya in another medium, and then voddat in koristuvannya Win2003. On vibir proponuetsya:
- Creation of divisions by staff Windows Server 2003, and then vir_vnjuvannya WD Align from zavantazhuvalny disk.
- Creation of distribution by the staff of Windows XP, and then vir_vnjuvannya WD Align in the same XP.
- Creation of distribution by the staff of Windows Vista / 7/2008.
- Modification of the WD Align installer from Paragon, so that it can be installed in Win2003.

For more options, like Win2003, the first option is simpler and superior (the other options were not overridden by me). Tom navodzhu report description options with an exciting disk:
0. Do not forget to plug in the jumper 7-8, just like you inserted it.

WD Align - a program for accumulators with Advanced Format technology

About accumulators with Advanced Format technology

WD accumulators with Advanced Format technology optimized for work with Mac OS and new operating systems Windows versions(Windows Vista and Windows 7) that are installed from scratch. Advanced Format technology vindicated by WD and other brewers hard drives with a method to increase the efficiency of the magnetic noses and the air to let out a larger storage capacity.

For correct functioning hard drive With Advanced Format technology, you may need to run the WD Align program after installing it on a new operating system, or with it as an additional storage device. The WD Align program sets the optimal position between partitions on storage devices with Advanced Format technology, to ensure optimal portability of their work in single configurations. (Report about configuration - in the table)

When installing Windows XP from scratch to one, I closed the contacts 7-8 with a jumper. If you choose this option, DO NOT run the WD Align software. In order to ensure the full security of the code, install the jumper, and also work on the obov'yazkovo before installing and releasing the accumulator. If you are splitting your accumulator into a sprinkling spice when installing Windows XP from scratch, DO NOT install a jumper, but run the WD Align program.

If you can copy any operating system (Windows XP, Windows Vista, Windows 7) to a WD storage device with Advanced Format technology, then you need the WD Align program. A lot of cloning software has not yet been updated to support storage devices with Advanced Format technology. Therefore, in order to secure the full code of these accumulators, it is necessary to speed up the WD Align program.

What does Advanced Format technology give me?
Advanced Format technology allows hard disks to speed up with the latest capabilities implemented in new operating systems. Zavdyaks and cultivators of hard discs can create more accumulative obligations: as today, so in the future.

What are the advantages of Advanced Format technology?
Advanced Format technology allows you to save more data on the same surface area of ​​a hard drive.

Can I install an Advanced Format storage device into my computer?
New WD storage devices optimized for Windows 7, Windows Vista and Mac OS X Tiger, Leopard, Snow Leopard. If you can install a storage device with Advanced Format technology into a computer that works under the controls of one of these operating systems, then install it as it sounds. Those who use old operating systems, such as Windows XP, and cloning programs, should run the WD Align program to secure the full firmware of their storage devices. (Div. Table with configuration options)

What is WD Align for?
The WD Align program allows accumulating storage devices with Advanced Format technology to be processed on new security under the management of old operating systems.

Will you run the WD Align program when the disk is reformatted?
Hi, you only need to run the WD Align software once, after the start Windows installation xp. In addition, as the cordonies are distributed with Windows XP will be optimized, the stench will be left on a larger space, so the disk will be reformatted or the file storage will be changed to a new one.

In which storage models does Advanced Format technology work?
Advanced Format technology is incorporated into current models of the WD Caviar Green family. Soon it will be implemented in models of other families and other capacities. On the labels of WD storage devices with Advanced Format technology, special installation rules are enforced. Be kind, get to know them before installing the accumulator.

Where to get the WD Align program?
You can take advantage of the WD Align program from the side of the website western digital .

Designed for most modern operating systems, such as , + , MacOS. The cich has a support on the software level.

For those who are quiet :

- like Winchester revenge one split ( single partition), It is necessary to install a jumper on pins 7 and 8 ( jumper pins 7 – 8):

- Yakshcho Winchester to revenge the sprat of roses ( multiple partitions), It is necessary to take advantage of the site western digital special that z її to help "virіvnyat" disk.

Yak koristuvatisya W.D. Align?

- transfer data from the “virtivation” of the disk to another nose;

- go to the side Advanced Format Hard Drive Download Utility;

- in the drop-down lists, select the need ( On which OS will you be running the Advanced Format hard drive?; Are you using a cloning utility?; Will this be the primary drive or a secondary drive in your system?; How many partitions do you intend to create on the drive?), Press Submit;

- register (a very thorough procedure: you need to register yourself first, and then register your hard drive by indicating serial number, Place of Purchase, Date of purchase, - only after that you take away the bagan for downloading ...);

- download and install the program following the instructions of the installer;

- run;

- at the window W.D. Align press Next;

- at the window Protect your data before aligning the partitions press OK;

- at the window Select partitions you want to align set an ensign next to the disk, which will allow viewing Western Digital Advanced Format, You can't yogo "virіvnyat") -> Next;

- at the window Summary press Proceed;

- Check out the completed operation (if the disk is unloaded and available on a new file, it can take up to 20 minutes);

- at the window Fix partition alignment operation succeeded press Back to wizard, If you want to turn around at the window (in a different direction, press Quit for exit);

- return respect: after the operation is completed, the disk icon in the window changes from Non-optimally aligned partition on the Optimally aligned partition:

Notes

1. Yakscho If you installed a jumper on pins 7 and 8 of the hard drive, then you need to remove the jumper before starting. It is POSSIBLE to start when the switch is installed!

2. How do you want to "virіvnyat" winchester vikoristovuvavat in zovnіshny USB-Boxing, connect a hard disk to the back SATA-Rose maternity pay(on the vicitated , Jumper on pins 7-8 is to blame but CLOSED!). run , "Reset" Winchester, if possible vikoristovuvati yoga in the wild USB-Boxing.

It turned out that I needed a terabyte HDD and a 5400 spindle wrapper (for which I need a lot of money ..). And in the store there is only one suitable one - WesternDigital series Greenpower WD10EARS with technology Advancedformat.
Just don't take it seriously, it's easy to flash Advanced format, normal disk: SATA-300, 64 MB cache, quiet .. The axis is like this:

Notes in the margins: Head parking technology guarantees that the recording head will not stick to the disc surface under any circumstances.

So, as the rulers of green "westerns" were already sticking with the problem of the over-the-top privilege of Green-iv, I did not rush to put the disk into the system, but went to the measure ... read ...

Everything that is written below will not be invented by me. But I can’t tell the author.
First of all: they are not alone.
In a different way: approximately one and the same copy from the site to the site, from the article to the article, and who, having taken a quote from someone, is unknown.
І in the third: I also delivered a handful of crumbs.
Have some kind of vipadku: thanks to the authors.

Theoretically and briefly Advanced format:
Plates on Volodarіv tsієї tekhnologiї split into sectors not by 512 bytes, but by 4 KB each, so that the first four-kilobyte file was saved on eight sectors, now only one is needed for this one. Apparently, in most cases there are fewer different service blocks (Sync / DAM, ECC), inter-sectoral gaps and sectors, less often filling in information.

What do you give?
Smaller number of downtimes, smaller number of pardons, great number of pardons for the treatment of danichs, more recording space, blah blah blah ..

What's so bad about it?
Windows 2000/XP don't mind practice with such discs zovsim.
Windows Vista and Windows 7 - yes. Ale do not know:

ale software security, Starting from the BIOS, it was created and is being created in the most important way for the expansion of those that the sector can expand 512 bytes.
І Western Digital worked out such a feint: physically, on the surface of the plates, 4-kB sectors are created, and the axis logically reports the disk about those that work with sectors of 512 bytes. Tobto, the skin of the physical sector to take revenge on your own highest logical ones. This is the axis of emulation ..

And here I will give more Quote:

"... On the right, in the fact that Windows XP is popular until now (as well as all її fronts) vikoristovu duzhe tsikava scheme zhorstky formatting disk.

When a partition is created on the disk, the first 63 sectors (from zero to 62) are reserved, and the partition itself starts from the 63rd sector. The 63rd sector itself in different physical 4-kB sectors is brought exactly to the eighth logical sector in the eighth physical sector. And then enter the file on the right NTFS system, which works with a hard disk in 4 kB clusters.

And we take a very unfavorable picture: through a 512-byte zsuv (the same 63rd sector), the skin cluster of the file system expands twice on two physical 4k-sectors, regardless of those that are beyond the stench of the stench. When reading, it’s less necessary to make it even more effective through the need to read a lot of more information, less required, and subtract from it the necessary pieces of data. And the axis on the recording of the hard disk cluster should be read two times, changing only those in the most logical sectors in them, as if they were following the addresses of the file system cluster, and only writing them back to the disk. Recording a 512-byte sector, and by itself such requests change information in system data, obviously, generating a reading of the physical 4K sector, replacing new data in the new data logical 512-byte sector and write physical 4K sector to disk ...

.. I realized that in terms of productivity it would be even stronger. what suddenly Microsoft choose the size of the starting access itself 63 sectors -At the same time, I don’t know anything, but earlier it manifested itself less with robots with RAID arrays (there stripes also showed damage to some clusters in the operating system) and SSD disks (through block access), then it immediately became a great problem ... glad one : y Windows systems Vista and Windows 7 do not have such problems, the shards of the system go to the disk layout in a different way ... "

Who is guilty, more or less clear. Now about those who work.

On the disk itself, the axis is as follows:

Tse won, bigger:

What does about the foot mean:

* in Windows XP: if you want to split the disk into a split disk, or if you want to clone the clone program, use the WD Align program.
* in Windows XP: if you want to transfer only one partition, which takes up all disk space - set the jumper 7-8 before installing the disk, or switch to WD Align * For all other operating systems - the disk is ready for "like є", so you don't need to do anything.

About the switch: if you put it, then the disk will collapse its entire logical structure into one logical sector so that the 63rd, from the point of view of the operating system, the sector will actually be the 64th, so you can spend it carefully on the cob of the physical sector. What is the solution to the problem. Poki jumper varto..
Ale.
I don't know how you would behave with a jumper disk if you have 2 operating systems, for example Windows XP and Win7.

And how about a jumper for chogos (well, raptom?) Know? .. I won’t lie - I don’t know either. And you? Dehto vvazha, scho in tsmu vpadku іnfu you can spend. You can twist it to the point :)

Those that I immediately amaze, and that vykonav zі his disk, you can know in the vastness of the Runet, having pored over in yoga hoards. Well .. I have chosen everything for you and for you, having analyzed it, having chosen it better, having tried it and resolving it and I will show it.

If you want to put on Green Power (and stink already є i z swidkіstyu 7200) operating system, I strongly recommend vikonati hover the procedure below on the computer already installed operating system . Otherwise, it can be done in such a way that, when occupied, your disk will not appear as a terrabyte, and the system will respect the cache size of the disk.

let's go:
Acronis True Image WD Edition is available free of charge for Western Green hard drives in Russia. In the same way, Russian Acronis AlignTool is free of cost.

In both programs, the pokrokovy master will not give the right to a pardon, only read carefully.

Install Acronis AlignTool.

Install Acronis True Image WD Edition.

After installing Acronis True Image WD Edition, you will need to restart. Turn off the computer, turn on the zhorsky disc western Green Power, after logging in, launch Acronis True Image WD Edition.

Why did I see the chervonim myself first , but not logical?

Yakscho V is not going to put the system and wines on the disk until the end of the century will be in your system block- then you can create a logical one (when you automatically create a small partition for service files).

However, if you fail to connect the logical disk to a friend - when connected to someone else's computer (especially via USB), there will be problems in different logical disk.
So what do I choose first .

The disk is now showing up in the system. But still not all!

Launch Acronis AlignTool.

The program itself know required disk and to determine that tse Chi is not optimally divided.

Bachite, - she knew and said: "I didn't make the optimal alignment."

Before the speech, I simply did not grasp one screen - everything seems to be very fast. Because the disk is innocently clean. And the axis yakscho on the new already є danі - everything will be richer.

press " Turn to maister", Schob perekonatisya, that everything is in order:

Vlasne - and everything.

Before we speak, once again: after the procedure of copying 600 gigabytes per western to a western (and not forgetting - the speed of wrapping in a new 5400) took 15 less credit, lower copying the same files on Hitachi with a speed wrapping of 7200. I don’t know why.

Before speech, two: the fact that in the Winchesters of the Caviar Green family the speed of the spindle wrap changes from 5400 to 7200 rev / hv in the fallow type is a myth. speed fast. Might be a trifle different, fallow like a model, ale fast. 5000 or 5400.

Before speech, three:
P.S. If I had mercy here - correct me.
Abo add.
The fact is that the situation has been corrected, if the disk is obligated to be bound by the cache, I still have to write a line.
That one n_koli .. That one vzagali - God forbid ...

If you are happy and you care that you are the last one, I’m glad to send you to the Contest glad, vote for the new one in the form for the competitive voting is angry. Maybe your voice will be the highest and the author for the sake of take away the prize!
