Failed to read a sector and snapshot

Thread needs solution

I've just upgraded from 2011 to 2012. When I tried to back drives C and D: (2 hard drives) I got:

Failed to read data from the disk.
Failed to read from sector '13,101,408' of hard disk '1'.
Failed to read the snapshot. (0x10C45A)
CRC error (0x100155): ⎂Retry/⎂Ignore/Ignore ⎂All/⎂Cancel

Googling this error suggest this has been a problem forever.

I then uninstalled 2012 and reinstalled it. This time there were no source drives listed.

So... I uninstalled it. Exported and deleted the Acronis section from the registry and reinstalled. The source drives are listed again but I got a failed to read, early in the backup.

Looking at the log I discovered http://kb.acronis.com/errorcode/ but when I go there it says there is no information on the error. Really? Your developers defined the error but failed to tell you what it meant, perhaps?

Perhaps you should ask them.

So I don't have a backup of my machine and no way of knowing if my old backups are valid as I can't really trust this product.

Has anyone seen this and the solution to it?

Hello Steve,

Welcome to our Forum, we're glad to greet you here.

We actually do have these errors described in the KB article alongside with the solutions. You can find it by specifying the error message in the search field at the top of the page.

Usually this error means that there are errors on the hard drive. In order to fix it, please go to
Start -> Run -> cmd -> chkdsk /f /r -> y and reboot the machine
Upon booting Windows will check the drives for consistency and fix the problems if any.

If it doesn't help, please contact either any Forum moderator via PM or support directly, and request a snapapi update for Acronis True Image Home 2012 (or whatever other product you're using).

This should solve the problem.

Should you need anything else or have any further questions - feel free to contact us at your earliest convenience, we will be happy to help you!

Thank you.

Steve got a My book Essential with USB 3.0 from WD by any chance?
they seem to have incompatibility with acronis true image 2012

Hi Tommyla,

Thank you for your comment.

I've checked our internal resources: we do have compatibility problem between My Book Essential and Disk Director 11, but nothing whatsoever reported regarding Acronis True Image Home 2012... Could you please kindly give us more details on this one?

Thank you in advance.

@tommyla, Re: My book Essential with USB 3.0 from WD
I have recently purchased such a drive; I love it, it works perfectly with Windows 7. However, the Windows Backup & Restore application does NOT work with this hard disk, look at WD support http://wdc.custhelp.com/app/answers/detail/a_id/6618/session/L3RpbWUvMT…. The WD article tells the drive has “4K Logical sector sizes”. “Not yet supported until Windows 8 or other release by Microsoft.”, discussion at http://social.technet.microsoft.com/Forums/en-US/itprovistaapps/thread/….

At the moment, I have not ATIH2012 installed on my system, but I have tried the Linux boot CD created with ATIH2012. No problems with recognizing My Book. I have just ran a partition backup (System + C:) with My Book as the destination. Completed successfully. I clicked the Extended feature (something like that), still running the Linux app. The Acronis app told me:
“The entire space is accessible; there is no hard disk with MBR partition style larger than 2TB in your system or sector's size on your disk is larger than 512 KB. All hard drives can be managed by Add New Disk tool.”

Windows Disk manager gives this info: My Book (Disk 1): 2795 GB NTFS, type Standard, partition method MBR, Upper filter PartMgr. Chdsk gives “4096 bytes in each allocation unit”.

thanks for the link to your KB article. I think the reason I missed this before might be that it says:

"This article applies to:

Acronis True Image Home 2009
Acronis True Image Echo
Acronis Backup & Recovery 10"

whilst I am having a problem with Acronis True Image Home 2012.

I have however run chkdsk on both installed drives and found no errors.
I downloaded SnapAPI but on installation it found a newer install so I aborted the installation.

My backup device is a basic (Sharkoon) eSATA disk dock with a WD Caviar Green 1TB drive in it.

As a test, I downloaded and installed an evaluation copy of Paragon Hard Disk Manager Suite 11. It managed to backup C: and D: to the external drive with no errors. I have not attempted recovery though.

Steve.
