3243: snapman.sys causing BSOD
- Login to post comments
I have True Image Home 2009 running on Vista Ultimate 32bit and I have been having numerous BSOD (like anywhere from 2-4 a day) and the mini dumps idicate snapman.sys causing the problem.
After reading threads here about BSOD on on features of True Image (such as Try and Decide, which I'm not using) I tested out a theory and at least one cause for this could be that when my external estata drive is on the BSOD will occur....come to think of it: I turned on my drive is morning and I instantly had a BSOD. Come to think of it, I was have a lot of these over a month ago....and then I haven't had a BSOD in over a month AND as chance would have it my external drive hasn't been on for that time.
I've had this problem over version 9709, 9788, 9796, that last one I just upgraded to two days ago.
Has anyone else had this problem? Can I just disable snapman and still use the backup/restore software?
Hello Brad,
Thank you for using Acronis Products
The system crash is caused by Acronis driver tdrpm222.sys that is responsible for Try and Decide feature.
I can suggest you the following workaround: you can delete Try and Decide drivers from the system so that the OS does not crash when you attach the USB drive. In the meantime I will forward the information you provided to the QA team so that our testers and developers could look into the issue and fix the problem within the program code.
Here are the instructions for manual removal of the Try and Decide module. Please note that this feature will not be available after this procedure.
- After installation of the build 9796 please go to registry editor (Start > Run > regedit). Then delete the following subkeys:
HKEY_LOCAL_MACHINE\SOFTWARE\Acronis\Tdrpman
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tdrpman228
- Delete string tdrpman228 from:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E967-E325-11CE-BFC1-08002BE10318} -> UpperFilters
and
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{71A27CDD-812A-11D0-BEC7-08002BE2092F} -> UpperFilters

Dmitry - Thanks for the reply. So you saying I should make these changes even though I am not using, and never have used, Try and Decide.....and the mini dump file says the likely cause is snapman.sys.
Before I saw your reply I found this article http://kb.acronis.com/content/1620 and followed it's steps to remove snapman....and I have not had a BSOD since.
I did sumbit a support request for this last week, along with the minidumps, but have yet to hear back.
Hello Brad,
Thank you for using Acronis True Image
Since you have removed the snapman.sys driver, you are unable to use Acronis True Image Home 2009, it will not work. To restore the system to the previous state you should install SnapAPI380 update available here and reboot the computer to complete the changes.
The issue conserning the USB drives is well known. We are investigating it, and there is no a solution at the moment.
As a workaround you can use Acronis Bootable Rescue Media for the backup purposes.
Thank you.
Thanks for your reply. I have opted to remove Acronis and use another backup software. FYI - My external drive is esata, not usb.
eSata has been reported as being problematical with other software as well.
You can't disable snapman.sys.
What type of USB drive do you have, something standard or something like a Western Digital Elements/MyBook etc.
Do you have a card reader attached to your PC?
Is the drive plugged directly into the PC or via an external hub?
If plugged into a hub, try plugging it in directly to the PC. If already plugged into the PC and using a front USB port, try one on the back of the PC.
