Windows backup the requested system device cannot be found

Why would my backup drive request a system restart? I can temporarily fix it by running a quick chkdsk on the backup drive, then it can disconnected.

But after I scan for new hardware and it gets back into the system, it won't disconnect again. We use 5, one for each workday. We use a scheduled task with HotSwap! I fixed this last week by removing the partition of the backup drive, then creating a new one. Then it could be disconnected using HotSwap! We already have SP1 in Server R2, so it's not that as someone mentioned above.

Some of the backups work, but then sometimes not. Just like someone mentioned earlier, maybe 1 out 5 fail. Would setting the backup using the drives "dedicated for backups" work better then using the drives as a volume visible in Explorer?

Anyone think having the backup drives visible in My Computer may be causing the problem? Make sure that the combined allocated storage for each VHDs doesn't matter dynamic or fixed do not exceed the total size of the physical drive that holds the VHDs. Once you get this right, the event ID should stop and backup should work fine. I hope this helps everyone.

Najmee IT Managed Services. My Server Backup fails on the "C" Drive. A review of the Event log gave more insight to the issue. Tried a few things with the External USB drive to no avail. So we replaced the External USB hard drive and the issues no longer exist. I'm having the same issue almost every day. If someone at Microsoft is interested to have details about this problem, tell me and I'll help until it's fixed.

I wrote to user Chirag but he is no longer dealing with such issues. The limit for me was something like characters for the length of the path up to the WindowsImageBackup directory created by WBAdmin.

I was doing tests with a tiny partition the. VHD is about MB and when I made a different path that was longer by 22 char , it suddenly failed. After a few tests I found the limit. The behaviour is completely repeatable. By the way, I think it safer for others to do their own tests, the limit may be affected by other factors. Better to try to have short pathnames if possible.
