Failed to write to sector

I was using Acronis Backup 11.5 to do a full disk recovery and I received the following error message:

"Failed to write data to disk" 
"Failed to write to sector '82,539,520' of hard disk '1'"

I clicked "Ignore" and this happened a few times with different sectors like 119,211,520; 281,378,304; 335,931,904

Unfortunately, I have to use this backup file. Is there any way to find out exactly what files are affected on my NTFS drive when I know the sector numbers? I tried to use Winhex program, but same logical volume sector and physical storage sector point to different places on the hard drive and I am not sure what kind of sector Acronis Backup program refers to.

Please help!!

Thank you.

Hello Nautilus,

Thank you for your posting! Are you attempting to recover the data to the original drive a backup was taken from or it's a new drive? How is the drive connected? Any kinds of RAID? 

General recommendation would be checking the drive's S.M.A.R.T status and validating the backup archive. If any errors found, you need to correct them first with e.g. dedicated diagnostic utilities from the disk manufacturer. If possible, try to user another destination for recovery. 

If you are backing up to the new drive, it might be worth to fresh formatting the drive before writing the data to it. We also recommend doing recovery with a WinPE-based bootable media that has better compatibility with various hardware sets.

Thank you,

Hello Ekaterina:

I used Acronis Media Builder to build a CD (Windows representation). I replaced the failing SATA3 drive with another drive same size, same interface, no RAID. The drive was almost new. I didn't have another drive and I was under a lot of pressure so I had to use that drive. It was preformatted with NTFS, SMART status was OK, but I think it doesn't guarantee that the drive is completely trouble free, correct? I did disk recovery, and my understanding is that with this method Acronis must write sector to sector, it cannot write to a different sector. And if there is a problem writing, it just gives an error message and continues on without trying to write to a different sector, is this correct?

My initial question was how to find out what files are affected on the drive when I know the failed to write to sector the Acronis Backup program refers to. I have figured that out myself. I used Winhex program, Tools, Open Disk, Logical Volumes/Partitions, Navigation, Go to sector, enter the sector number and the widget on the right will show you the affected file name. I hope this will help somebody else.

Sorry for not getting back earlier! 

And if there is a problem writing, it just gives an error message and continues on without trying to write to a different sector

There will be informational messages that some sectors on the target location are bad, but the data should be written to the healthy parts of the drive instead e.g. if you restore to original location the backed up pieces of data wouldn't be matched sector-by-sector with the original order, as per my understanding. I'll try to find more info on the way we are placing data during recovery.
