I thought it might've been something like I need to defrag it or something. So when I tried to analyze or defrag it in Disk Defragmenter, it tells me that chkdsk is scheduled to run on the volume (E:). So I try to run Disk Defragmenter through the command prompt (chkdsk /f), but it says that it can't (due to the volume being used by another process). I try "analyzing" it through Disk Defragmenter in Safe Mode, but it gives me that chkdsk message again. The same thing goes for the "chkdsk /f" command through the command prompt in safe mode.
The funny thing is that it's only my E: partition. My C: partition, which makes up the rest of the master drive, can get analyzed, defragged, etc. just fine, as well as my slave partitions.
Figure it's just my hard drive going bad? Any ideas?
