Can't assign a drive letter to a partition from the backup archive error
I am running the following: Acronis 2009 build 9809 On August 10, after doing a full new backup to an external Western Digital drive and attempting to mount it, I got this error:
Cannot assign a drive letter to a partition from the backup archive
After much experimenting, I discovered that I can mount this partition in "read write" mode, but not in "read only "mode. I have other backups on this drive and I am able to successfully mount them in read only mode.
I redid the backup a number of times several times changing the computer configuration as follows:
- disabled Norton antivirus and firewall while Acronis created the backup and during the attempt to mount the backup
- removed all software that was installed after the time that Acronis worked correctly
- rebooted the computer after all these changes in configuration
Acronis still failed to mount the backup in read only mode. I am running Acronis 2009 build 9809, Windows Vista Home Premium, SP 2. Thank you for your help.
Hi, I tried assigning another letter (Z) & that did not work. When I have nothing mounted, no virtual drives show in Device Manager. Again, I can successfully mount in read-write mode. Thank you.
You might consider running the TI install program again and choose the repair option. I don't know if this would help. Maybe Acronis support can offer some help.
Thank you for the suggestion. I completely uninstalled TI and reinstalled it. The problem remains.
I do not know the cause. What is unusual is that you can do one but not other. At this point, I am offering suggestion with no basis for the suggestions--hoping one will be a solution.
If it were me, my next step would be to check the windows system for disk and file errors. This could take some time. If you do it, then do it just before you go to bed, etc as it will take several hours.
From a command prompt
CKHKDSK X: /R (where x is the actual drive letter)
The results will appear in the Events log under the Applications and the start/finish time.
Thank you again for your suggestions. Unfortunately, still no change. Here's what I did:
-- ran CHKDSK on all the drives (C, D, and the Western Digital external drive). It cleaned up the minor problems that were found.
--ran complete new full backup with Norton firewall and virus protection turned off.
--attempted to mount again by assigning a different letter
Acronis TI will still not mount in read only mode.
I know this is an old topic, but i have encountered exact the same problem :
The mounted volume appears and can be accessed while the 'assigning letters to partitions...' dialog is running but then disappear when the error message appears 'Can't assign drive letter...".
Tried using different drive letters and to mount in read-write mode, but no luck.
Reinstalling Acronis True Image did not fix the problem.
I also had another problem at the same time, when i connect a USB memorystick or memorycardreader.... , it always keep asking for drivers,
while this normally where installed automatic by windows buildin drivers.
I had to point each time to the location "C:\Windows\Inf" for the drivers to get installed automatic and after that,
the USB memorystick works till a reconnect the USB memorystick, and it ask again for installing drivers.
When a fix this problem, the problem with mounting of images also disappeared.
The problem was in my case 1 registry value that pointed to another location then "C:\Windows\inf" ,
this key can be found at this location in the registry :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion
Look in the right pane for the key named "DevicePath" , it must have a value "%SYSTEMROOT%\inf"
Good luck ;-)
