Windows 7 BSOD on mapped external drive


Been using the Backup with retail Win 7 Prof 64-bit for about 12 days with no problem until yesterday when I hit a load of BSODs. I’ve pasted a crashdump analysis for info. Cause is CBUF.SYS (this file is reported in the BSOD itself).

I have been mapping my HTC phone as a mounted drive via the USB port. This is fine copying TO the mounted drive UNTIL I try to rename a file on the mounted phone drive - instant BSOD.

It also happens when I mount a file as a drive using TrueCrypt. As soon as I try to rename a file on the mounted drive, again BSOD. Both are very reproducable. I see the system can’t examine cbuf.sys for some reason? I have no problems with local and network mapped drives.

For the moment I’ve unistalled Comodo backup.



Please use the updated version 2.1.118414.11
Do you have any dump files?
Please post them

I am having similar problems synchronizine my iPod. I get a BSOD pointing to CBUF.sys. 2.1.118414.11 is not (yet?) on the download site. Where can I find it?
