Data image - unable to produce next image, plenty of "failed to read from sector"
ATI 2009 Home
A NTFS partition with documents on it.
No apps, no OS no it.
It is always being imaged by one full and several differentials.
All images land on special partition.
Now, the last attempt to produce new differential for this disc within existing
image series produces errors as in attached log file.
chkdsk /r /f performed shortly before.
What's the possible reason?
How to recover from this situation?

It is a data backup (files and folders)
chkdsk /r finds that some files are looked and it is impossible to close the open files.
That's good so from my point of view because plenty of cache files/directories are also placed on this disc.
So the chkdsk /r asks for scheduling the scan on system boot.
I answer with NO because one day ago the scan performed on system boot, initiated from GUI
with the two options available there checked. No improvement after having performed all that.
Yes some software installations were made in the meantime but no of them failed.
It is very possibly that some new pictures or zip files were stored on this partition recently, before the problem occurrence.
Yes, it has been a power cut or similar recently.
Generally I am able to browse through folders within backups. I am also able to open a pdf file stored there.
Chkdsk scheduled on system boot for all present partitions already performed. No improvement after that.

I think it would be a good idea to allow chkdsk to run again, at least then we can rule out disk corruption. Have you defragged the drive recently or is it an SSD drive?

Well, chkdsk /r repeated few times.
No improvement.
Scan logs show some lost indexes.
Before I write more about found logs I give more details about station setup.
Two hard disks installed. Both are conventional magnetic. No SSDs installed.
First of them (Windows Computer Management, Disk Manager reports this as Disk 0): whole its space assigned to extended partition. First 40GB assigned to logical disk, swap file placed here. Last 12GB assigned to Acronis Security Zone. The rest in the middle not assigned to any logical discs.
Second of them (Windows Computer Management reports it as Disk 1) partitioned to two primary partitions and one extended. First of primary partitions is a system disk with windows xp installed on it. Rest are partitions for documents, post, cache, temp directories, multimedia contents (D: and E:), dedicated partition for ATI image/backup files (Z:).
C: and D: can be scanned possible only on booting, due
to fact as described below. However, on your last request
I started the scan of D: through GUI and it executed immediately without scheduling for boot. No errors found
during that scan.
Regardless of which Disk's 1 partition is scheduled for on-boot scan, which not the winlogon service reports always for C:
Cleaning up 1 unused index entries from index $SII of file 0x9.
Cleaning up 1 unused index entries from index $SDH of file 0x9.
Scan of C: several times performed. Every time the log report as above arises.
Exact the same error report generated one for the swap file dedicated partition.
However, up to now no problems while using windows and the apps installed here.
The problems reported here occur while executing ATI task. The task should perform data backup of D:.
Beside of produced log files, the progress bar never gets green, nor partially. It is hard to stop the task as soon as apparently got hanged.

The error messages as attached to thread starting post are referring to "hard disk 1".
How to find out which of two installed hard disks are being
referred here to?

Acronis begins its disk numbering with 1 disk 1 should be the first disk pictured in the disk management picture.
Another possibility, you could simulate a backup and I believe 2009 will number the disks for you.
If you have the space, consider this
The data file differential backup attempting to be completed is the data files which were either created or modified after the full backup was made.
Consider doing a dated(to-from date) file search and locate all the files which is to included in the diff backup. Attempt to copy all the files into a new folder and see if Windows balks at the copy. If successful, then delete the originals and see if they helps any.
When doing a chkdsk and you have multiple disks, try using the commands
CHKDSK X: /F /R and use your real drive letter for the X

Hello all,
Thank you for posting and your help.
chrizio, I would also like to help you with this.
Please check this article for the solution and if it does not help, I would really appreciate if you can get back to me with this report so that I can take a look at your hard drives. Also, are the backups being saved to an external hard drive?
Let me know if you have additional questions please.
Thank you.

I know now more history of this hdd.
It has had a crash one. Middle range has damaged
material. Two partitions created, one at the beginning of disk, one on its trail. First used for swap file latter for ATI's Secure Zone. They do not touch each other.
There is physically a gap between them two.
Owner had analyzed with some disk analyze tool how is the number of first damaged sector and how is the number of last damaged sector. So these two partitions do not cover disk range with sectors identified as bad.
Are the sectors being reported by ATI the sector numbers on physical disk or on particular partition?
