Problem with Windows Server Backup 2008 R2 with Advanced Format (4K) drive.

    Question

  • I'm trying to use an Advanced Format drive (4K sectors) with Server 2008 R2 Backup.

    If I format the drive using Disk Management as normal. Windows will create a partition on the drive that is 4K aligned, and all is well. I can verify that the partition is aligned by running Acronis WD Align.

    I then set up a scheduled backup in Windows Server Backup 2008 R2 and specify that I want to use the drive for backups only. Windows Backup then re-formats the drive for it's use. However after checking with Acronis WD Align the new partition that Windows Backup has created is NOT aligned on a 4K boundry. This causes performance problems.

    If I use Acronis WD Align to re-align the partition correctly; Windows Backup will no longer recognise the drive as a valid backup destination.

    Is there anything I can do to force Windows Backup to create a 4K aligned partition, or is my only option to buy new drives that use 512 byte sectors?

  • I would also like to add a solution that I found that has worked for my 3TB WD Elements drive. Out of the box this drive did not work with Windows backup at all. WD support actually came through for me on this issue and pointed me to the following solution:

    http://wdc.custhelp.com/app/answers/detail/a_id/6618/session/L3RpbWUvMTMxMzUzNzc5My9zaWQvT1hrMSpJQms%3D

    Basically it consists of formatting the drive with their external drive formatting utility in "Factory Default" mode rather than XP-Compatible mode which (ironically) is how the drive ships. After performing the format, the drive works fine with Windows backup in both Windows 7 and Windows Server, but is incompatible with Windows XP. In my case, this is an acceptable compromise.

    This is how the drive appeared out of the box:

    C:\Windows\system32>fsutil fsinfo ntfsinfo H:
    Bytes Per Sector  :               4096
    Bytes Per Physical Sector :       <Not Supported>
    Bytes Per Cluster :               4096
    Bytes Per FileRecord Segment    : 4096

    This is how the drive appeared after the "Factory Default" format:

    C:\Windows\system32>fsutil fsinfo ntfsinfo H:
    Bytes Per Sector  :               512
    Bytes Per Physical Sector :       <Not Supported>
    Bytes Per Cluster :               4096
    Bytes Per FileRecord Segment    : 1024

    Finally, I should point out that this utility will probably not work for drives from manufacturers other than Western Digital as it scans for WD drives specifically on launch and is likely working directly with their drives' firmware. That said, I do believe this should cover all WD drives 2.5TB and larger to correct this issue.

  • Hello,

    Hard disks with 4k sector size are not supported by Windows Server Backup. It supports 512 sector sized disks. To use high capacity disks you can use 512e (512 emulated) disks instead. Here the physical sector size is 4k but the logical sector size reported to Windows is 512. There are performance impact though in the conversion between 512 to 4k.

  • How can I convert a 4k AF drive to use 512e? Is there some type of utility provided by MS to do this?

  • I'm curious of KB982018 resolves this issue (http://support.microsoft.com/kb/982018)?  This Recommended Update just installed on my system yesterday, and the details on it show that it seems to address many of the compatibility issues Win7/2008/2008R2 had with Advanced Format and Advanced Format via USB.

    So were the limitations for the TARGET disk with Windows Backup a system level issue or would there be issues with the program itself that remain?  I am just installing a new SBS 2011 server at an office and I want to use 3 TB USB 3.0 disks for the backup target.  I hope it can work now or very soon!

  • I did this hotfix on our hyperv 2008r2 server to support our new wd essentials 3tb external drive

    however it doesnt seem to have fixed the issue

    did you have any luck?

    im installing sp1 to see if that will help

    if i dont get this working soon i will be taking the HD back and getting something else

  • I just picked up a WD 3 TB External at Costco.  The 3 TB was on sale for only $5 more than the 2 TB model!

    Well it looks like it's going back.  Windows will not image to the drive.  I tried GPT partitions and MBR partitions, at and well below 2 TB and it always fails.

     

    AndrewITECH: I didn't get the same error as you.  My server did properly report 4096 for the Bytes Per Physical Sector.  The server I have is MS SBS 2011 Std, which is 2008R2 with Exchange, WSUS and SharePoint added in.

  • I'm getting the same error I have a WDC 3TB USB 3.0 drive which I just purchasad. This does support Advanced format 4K sector and should be supported by Windows Server 2008 R2 SP1. Microsoft just realeased a hot fix to resolve advanced fromat disk drive issues (4096 hard sectors). I'm trying it now, but thought I'd give folks a heads up. http://support.microsoft.com/kb/982018. Unfornately, the KB hotfix didn't help, but does indicate Windows Server 2008 R2 SP1 now supports advanced format but only for 512 byte emulation (512e) on top of 4096. Native 4096 is still not supported, but Msft is investigating per KB article.

    Related thread here on Technet forums: http://social.technet.microsoft.com/Forums/en-US/windowsbackup/thread/5d9e2f23-ee70-4d41-8bfc-c9c4068ee4e2

    Any thoughts?

  • Sent back teh WDC myBook Essential 3TB USB 3.0 drive for a refund. Going to try Seagate's 3TB Freeagent GoFlex as it appears to automatically adjust to 512e. Hopefully this resolves the problem. It'd be best if Msft supported native 4096 sectors as its the best performing.

  • I have the 3TB GoFlex USB 3/2 drive and am trying to use it with Windows Backup to back up a Windows 7 Ultimate system running on an iMac (that means GPT partitioned disks and EFI boot, not BIOS).

    The backup works fine going to a 2TB Western Digital Basics drive -- although it takes 18 hours to image a disk containing 1.2TB of data.   It doesn't work at all going to the 3TB GoFlex -- either using USB 2 or Firewire 800.   When used directly by Windows for file storage, the GoFlex 3TB drive works fine with either interface.  I'm using FW800 mostly because it's faster than USB and the stupid iMac doesn't have USB3 or E-SATA (other than the numpad-less wireless keyboard, it's a great Windows machine ever other way).

    So I guess we'll all be skating on thin ice until Microsoft fixes Windows backup.  BTW, I tried Acronis 2011 as well, including the extra cost "plus" add-on that supports GPT partitions and it still won't back up my system, probably because of the EFI BIOS or the unrecognized OSX partition.  So that's kind of useless as well.

  • I have tried two Seagate FreeAgent GoFlex Desk 3 TB USB 2.0 drives and they are not working with Windows Server Backup on SBS 2011 (based on Server 2008 R2 SP1).

    KB982018 ist not fixing this problem.

     

    Wednesday, July 13, 2011 2:33 PM
  • To provide more details:

    Backup stores the data in VHD format. This VHD format is not supported on 4k sector size disks therefore backup won't work. As suggested earlier, please use 512/512 emulated disks for storing Windows backup.

  • I'm also experiencing the same Windows Server Backup issue with a 3TB WD Elements external hard drive that reports the following despite instaling KB982018:

    C:\Windows\system32>fsutil fsinfo ntfsinfo H:
    Bytes Per Sector  :               4096
    Bytes Per Physical Sector :       <Not Supported>
    Bytes Per Cluster :               4096
    Bytes Per FileRecord Segment    : 4096

    I did contact WD and they seem completely uninterested in providing a list of 3TB drives that are either 512k sector sizes or support emulation. I don't even know if WD even make such a drive in 3TB sizes.

    So now customers are stuck with what is by now current-gen hardware that has no support from Microsoft, which I'm certain full well knows that sector sizes are effectively never made available by the hardware manufacturers. Nor does there seem to be any comprehensive hardware compatibility list.

    I can't reasonably imagine that it's technologically infeasible for the software to support 4k sector sizes so I can only surmise that Microsoft is intentionally turning a blind eye on this issue.

    So as a result of this, I'm going to be stuck trying to find a new 3TB drive that supports emulation in order to back up my 3TB RAID5 array to replace my brand new 3TB drive that doesn't work. The other alternative is Acronis backup software which unfortunately costs over $800 for server software. Truthfully there are really no excuses for this!

  • I would like to add to this thread after I have spent many many man hours researching this issue and working with Hard Drive vendors to find out what is going on.

    This problem not only affects Server backup but Windows 7 Client backups as well. Bottom line is that System Image backups will not run and the backups fail(by the way a System Image is included by default in all Winodws 7 backups). After scouring the KB and Internet I have found that Microsoft has known this has been comming for almost 3 Years now. All new drives from most manufacturers are being shipped with 4K sectors. This includes 500GB USB drives and they cannot be changed to 512K or 512e to work. I worked with Paragon Software and it cannot be done. Here is KB Article about Microsfts "position":

    http://support.microsoft.com/kb/2510009

     

    Here is what is happening Microsoft:

    Regualr (non-IT) People are buyuing new computers and buying an external USB drive to run backups. It fails. They return the drive thinking it is defective. They get another drive and it fails. They return the computer and buy a MAC and use Time Machine with any USB Drive.

     

    I tried to call Partner Tech Support for this and explain and they wanted to charge me for a Support Call. The Storage vendors told me Microsft has to update the Backup Software.

    I understand I am a small Fish in the pond however someone needs to wake up and FIX this Backup Issue.

     

    Untill then we will need to buy 3rd Party apps that will work with the 4K drives that are now being shipped as Standard.

     

    Microsoft you knew this was comming.

  • Hi,

    We have enabled 4k Sector size Disk support in Windows 8 backup solution. In Win8 Server you can take backup to > 2 TB disks with 4k sector size.

    Win8 Server Developer Preview is available at MSDN here: http://msdn.microsoft.com/en-us/windowsserver/ 

    We would like to hear from end users about their experience.

    Note: This is not a promotional request. Please reply back if you face any issues in using 4k Sector size disks with Win8 Server backup. This is also applicable for System Image Backup in Win8 Client OS.

  • This doesn't help help my company that just bought SBS 2011 three weeks ago.

    Microsoft knew this was coming? Microsoft held the first summit to discuss the new size in June of 2005!!!

    I've read in a lot of places that I should use a disk 2.5 times the size I'm trying to backup. I have a 3 disk RAID 5 system that has 1 TB of space. That means I need at least a 2.5 TB hard drive. Nobody sells one that supports the prehistoric 512 sector size.

    How am I supposed to backup my NEW system? If the backup program was something they were selling individually, they would've fixed it years ago. Since it's just another asterisk on their product description page and nobody knows it doesn't work until after they've spent their money, I guess "why bother fixing it", huh?

  • I've been having the same issue (Error 0x8078002a) with windows 7 ultimate. 

    Just bought 3 2TB WD Caviar Black (sata 6G) drives for my backup server, installed them in the new machine, created the array (raid 5), and now have a 3.9GB array.  I format the drive according to the mfg instructions and viola!  Working drive right?  WRONG.

    I now find out that I cannot utilize windows backup on my backup server.  It fails both locally (backing up the C drive of the backup server) and remotely (backing up a client PC).  Same error at about the same point in the process (50%)

    I've also been having problems with my 2008 R2 webservers backing (completely different windows backup problem, don't get me started).   All I can say is that I am occasionally successful backing up the servers.  I was dreaming that I could use my new, you know, backup server to backup my servers....   Nope.  Seems to be a theme lately.

    Backup is SO critical, and it's freaking me out every day.  Any solutions???  Please!!!!!  HELP!!!

  • Windows Server Backup won't backup anything over 2 TB, which leaves slicing the RAID or buying a real backup program.  Barracuda's Yosemite is $1500 and covers all servers in your environment... just sayin.. 

     

    I'm a bit pissed I can't backup to a 3 TB external though... guess the 4 TB I was getting will be on the shelf till I get my RHEL box up...

  • Vikas - any idea when SBS 2011 will support 4K? 
    Wednesday, December 21, 2011 7:48 PM
  • As I know,

    SBS 2011 is based on Windows 2008 R2 Server. Backup uses VHD (Virtual hard disk) format to store the data. The 4k Sector support is not available for VHD in Windows 2008 & R2 (VHD cannot be created on 4k sector size disks). Hence backup cannot provide support for 4k disks.

    In Windows 8, a new VHDX format is created that supports > 2 TB data storage and 4k sector disks. Therefore only in Win8 the backup is supporting 4k sector disks.

    When the Win8 based SBS systems will be launched then you can expect support for 4k.

  • Vikas, 

    This is a ridiculous answer coming from MSFT. Windows 7 is your CURRENT operating system on the market and the backup software doesn't support some of the most common USB hard drives on the market that are being sold and used primarily for backups?!?!  And all you can promise customers is that it will be fixed in Windows 8 which we have no idea when that will be released? 

    Updating the backup software via a KB Hotfix would be the more appropriate response here.. Not telling us customers that we can't backup our CURRENT machines using the currently available and most common hardware on the market.

    EPIC FAIL...   :-( 

    Please forward this message to the Windows team or whatever team maintains windows backup. This is one of those times when the company needs to take a better path to supporting customers to compete against the likes of Apple.  Just sayin' ...

  • This is rediculous, many people now are using Enterprise NAS for smb cloud and storage, and windows backup can't to supported networ files system. Has there been any more updates for this since the hotfix ?

  • Vikas Ranjan -

    What I find so strange about this: I have been doing image backups from an WinServ2K8R2 onto a remote disk mounted on a WinServ 2K3 machine for 1.5 years. That disk is an external Seagate FreeAgent GoFlex 3TB. The VHDs are stored on the disk without issues. However, if I attach the drive via USB directly to the WinServ 28KR2 machine then image backup will not  work. Incredible. there are quite a few other words I have for this ridiculous situation but this is a public forum. Pathetic might be an acceptable word for this forum. 

    When I found this forum thread I was stunned. Image backup does not support drives with Advanced Format 4K sectors. Incredible. To be taken seriously as an enterprise level product how is it that Microsoft has not fixed this glaring omission/oversight.

  • Vikas,

    Ditto - What glahens said. I am going to spread this knowledge far and wide now that I know.

  • Hello,

    Hard disks with 4k sector size are not supported by Windows Server Backup. It supports 512 sector sized disks. To use high capacity disks you can use 512e (512 emulated) disks instead. Here the physical sector size is 4k but the logical sector size reported to Windows is 512. There are performance impact though in the conversion between 512 to 4k.

  • The SeaGate GoFlex 3TB USB 3.0 will give you the exact same problem, looks like there is no way of changing the format to 512 or 512e sectors to be compatible with Windows backup.   

    Windows 7 x64 backup and create system image will fail with error ( 0x8007045D ) and  ( 0x8078002A ).

    I have no problem at all with FreeAgent GoFlex 1TB which shows bytes per sector 512.

  • The only answer that I'm looking for is when will the Windows Server Backup software support the new 4k drives?

    Is there developmend in the pipeline to sort this issue out?  Getting 512e drives is impossible for me now.

    Anyone know the answer?

  • In the context of Inbox Backup software -

    Win2k8/R2 based Systems will not have the 4k drive support. Win 2012 Server backup provides support for 4k drives.

  • I would also like to add this too... I have bought a Western Digital "My Passport" 1TB USB3.0 2.5" to use Hyper-V under Windows 2008 R2 on my laptop, and my VM's starts fine !

    The P/N of the Disk is "WDBBEP0010BBK-01" and the model is "WDBBEP0010BBK-EESN"

    This is the fsutil result:

    NTFS Volume Serial Number :       0x4e1aea7b1aea6007
    Version :                         3.1

    The Disk drive was not formatted with the WD Quickformater tool.

    Thanks you CoreM, you saved me !

  • This solution seems to have worked for me with a WD 3TB My Book External Drive.

    Download and used the WD Drive Formatter to format the drive to "Most Compatible (Vista or later required)" 

    This changed the sectors to 512K on the drive.  I then change the backup setting from the SBS Console to add a new Drive Destination. It looks like this did the trick because the backup has not caused an error and is writing data to the drive.

  • To get Windows 7 to Backup Data on a Device greater than 2,2TB following steps worked for me:

    First, get the update for Windows 7 as discribed above. (It should already be on a frequently updated System)

    Second, make sure that you have the latest BIOS update of your Mainboard

    Third, if you have an Intel chipset you need the Intel(R) Rapid Storage Technology Driver to v10.5.0.1026 or higher for full HDD support.

    After doing that with my P7P55D Mainboard the normal Backup seems to work.

    The systembackup still won't though. Still working on it. :)

  • I am also amazed at this.  I have a new 3TB Seagate Backup Plus USB3 on a windows server 2008 R2 enterprise, I usually hate third party software, and so immediately formatted the drive to prepare it for Windows Server Backup, as I have done for all my other backup drives (though smaller and a different vendor).

    Windows backup fails to write to the disk, after setting up the schedule.  Incredibly Seagate won't acknowledge that there's an issue.  Their trouble shooting solution was "well, if you can drag files to the disk then the disk is fine."

    But as you know, once you set up a disk for Windows Backup it is not visible in the UI of the OS.  Dumb answer.

    I suppose MS is forcing us to update to a new server os.  I'm going to have to go back to smaller disks I guess.  unbelievable.

  • Ditto here to johnarmentrout. Even the same product. Seagate says to contact MS. MS says contact Seagate. Copies are OK, but backups don't work. Both of these companies are....
