My Windows 7 box had been running quite happily with a bunch of services on it (Plex, Bittorrent Sync, IIS). Since I have been running DrivePool (and scanner) I have been getting many blue screens, probably at least one per day. I am pretty sure it happens when Plex is streaming something off of the pool, but that process was previously running totally fine without crashes. The most recent blue screen is attached. I also remember seeing some of the previous BSoD's referencing cdfs5.sys. I have tried turning off network boost and even duplication on most of my folders so that the app shouldn't be that busy balancing or anything like that.


I have 8 1.5TB drives in the pool and one 80GB SSD (OS drive). 4 of the drives are in an eSATA dock and 4 are in a USB2 dock.


The really annoying part is that Windows is set to reboot on blue screens, but it hangs on these blue screens and has to be rebooted manually.

That's. .... really bad.

"BAD_POOL_HEADER" usually indicates memory corruption. It's not always, but usually a faulty stick of RAM. :(


And that 'cdfs5.sys' BSOD seems to indicate that as well. Specifically, that appears to be the CD-ROM File System Driver.


First thing I would do is run a memory test on the system. See if that is the issue.

Then run "chkdsk c: /r" (this will require a reboot and offline scan).

Then run "sfc /scannow".


If you're still having issues, it could be an issue with the SSD.


However, could you upload the crash dump?
