Cannot read sector / Incremental not possible

Hi All,
I'm running TI Echo Workstation Build 8206 on an XP Pro SP2 machine. I have read through many, many posts regarding my problems, but have not found definitive answers.

I set up a full image to run Sunday overnight, that I call "Weekly" and a separate, differential image to run every other day overnight, that I call "Daily". I haven't yet decided out how many previous backups I want to keep archived, but getting them to run reliably is the problem at hand. I'm swapping 2) WD 1TB Essential USB drives every day so I can keep one drive off-site.

Originally I got the email message "Problem Info: Failed to read data from the disk. Problem Details: Failed to read from the sector 488,397,234 of the hard disk 1."

I ran chkdsk, and it found one bad sector that was where a log file was located. After that, backups ran okay for a few days, then I got "Problem Info: Incremental backup is not possible. Problem Details: The file you have chosen is not the Acronis True Image backup, or the file is corrupted, or this is not the last volume of multi-volume archive. Do you wish to proceed with the current file name? If you proceed, the chosen file will be overwritten and the full backup will be created. Otherwise, you will create an incremental backup by choosing the valid archive file name or the last volume of multi-volume archive."

Originally I had selected "ignore bad sectors" and "no user interaction", since it runs overnight, but it still stops when it encounters a bad sector, and if I have quiet mode selected, I get "Error 4/8/2009 9:30:14 PM Cannot perform this operation in the quiet mode. (0x103F1)
Tag = 0xFDC1CBDF2C2335B6
Incremental backup is not possible. (0x64006C)
Tag = 0xFDC1CBDF2C2335B7
13 Error 4/8/2009 9:30:14 PM Operation has completed with errors."

My first question is - Is there a problem with swapping drives daily so I can keep one off-site? Is that what the "corrupted file" error is about? For a differential, doesn't it just look at what files are different from the ones on the full image file that it finds? If so, why should it care which drive is connected?

And second, what is the "ignore bad sectors" switch for if it can't ignore them?

I haven't tried installing the snapapi drivers, because on one thread, Acronis tech support said there are different drivers for different program versions, and one should ask them for the correct driver.

I would appreciate whatever help you all can give me - I've been battling this for weeks and will soon have to consider trying a different image program if I can't get this to run correctly unattended! Thanks!

 

Update: TIEcho was hung since Saturday, waiting for user input. I called in and had them answer "Yes" and the image completed in an hour. This is the first instance of a backup with this particular filename, so it ran Full instead of Differential. Can anyone tell me why it couldn't figure this out on its own and just run unattended? There are other tib backup files in that directory, but that shouldn't be an issue, right?

Hello bmiller,

Thank you for using Acronis Corporate Products

First of all, please verify the archives for corruption, it can be the root of the issue. Also, do you perform the backup operation under Windows or under Acronis Booting Rescue Media?

Please provide us with the diagnostic file:

Please download Acronis Report utility available here and run it, create a report and attach the file to your post.

This would provide us with detailed information on the hard disk partition structure.

Thank you.
