Locking Partition C - The Request Is Not Supported

Thread needs solution

Please could you help?

I have Acronis True Image Home 2010 installed on a machine running Windows Vista. I am backing up to a NAS. I have managed to take a couple of manual backups and one full scheduled backup but now, my scheduled backup jobs fail after approx. 14 / 15 minutes each and every time and the log reads as follows:

Locking partition C....
The request is not supported.
Error occured while creating the file. (Click Browse to specify volume location, Retry to try again, or click Cancel.

Terminated By User

I don't understand why it says 'terminated by user' as I do not intervene at all. Can anyone shed any light on this please? What might be causing this? What can I do to begin troubleshooting?

Any suggestions are very much appreciated. Thank you in advance.

Hello Racmarric,

I understand the question and will do everything possible from my side to give you a clear explanation.

Make sure the user account on the NAS, under which you are trying to backup to it, belongs to the Administrator group. The Administrator group should also belong to READ/WRITE group.

NAS buffer may overflow if the files are larger than 2 GB. Try setting Archive splitting in Acronis True Image to 2 GB:

1. Click "Tools" and select "Options";

2. Click "Archive splitting" and set the size to 2 GB.

If the issue persists please attach log file with the error message to your next reply.

Could you please also download Acronis Report utility available at http://download.acronis.com/support/AcronisReport.exe and run it, create a report and send it to us? Please compress the Acronis Report output file into an archive (e.g. with WinZip) and attach to your message by browsing for the archive. This would provide us with detailed information on the hard disk partition structure.

Let me know if you need further assistance.

Thank you.

Dmitry,

I'm having the same problem w TIB10 Eval and XP SP2.

I set archive splitting to 2G as you suggested above. It's too soon to light cigars, but initial results are encouraging. "Time Remaining" changed from idiotic numbers (43,000 days) to 18 minutes. So far so good.

Dmitry!

Good news and bad news.

For the first time ever, thanks to your advice, I actually got TIB10 to save a backup copy.

Strangely, it refused to save to my external LaCie FW800 drive, and defaulted to saving to the boot drive. This is not good. I am aware that I have CRC errors in my RAID 0 boot drive. This is the whole reason I'm trying to get the data onto another drive in the first place.

I've attached a copy of my log file. Hopefully you can give me a clue as to what went wrong.

Thanks,
Ed

Hello Ed,

Let me shed some light on the issue.

According to the log file, you have some serious error on the hard drive and you need to replace it or try to fix the errors by the means of chkdsk utility:

  • Go to the Command Prompt (Start -> Run -> cmd)
  • Enter the command: "chkdsk DISK: /r"

where DISK is the partition letter you need to check. Please note, that checking the C: drive may require you to reboot the machine.

You can also create a backup archive using sector-by-sector approach. In that case there shouldn't be such errors.

Additionally, could you please clarify what happened when you tried to point True Image to your LaCie drive as a backup destination?

We are looking forward to hearing back from you at your earliest convenience.

Thank you.

Hi Ilya,

According to what I have read, and supported by my experience, CHKDSK is not effective on a striped array. My boot drive seems to be dying. I am trying to save what I can before if goes permanently. I'm trying to learn to use TIB10 at the same time.

Imaging the boot disk isn't working out. The disk error seems to be the main reason. Weird disk behavior has also occurred. Over a period of days there have been multiple backup failure types, too many for me to remember. At the moment I am trying to save the data only. So far so good. I will then try sector by sector and see what happens.

What I would LIKE to do is to use Disk Clone to copy the striped drives onto a single new bootable drive. I don't think that will work out because of the errors. How does sector by sector work? How is it different from "ignore bad sectors?"

I could not tell why TIB would not use the external drive. The log indicated TIB could not FIND the external drive - that it did not exist. TIB defaulted to writing to the boot drive. Of course, the external drive was present.

Thanks,
Ed
