I have a critical workstation here which I set up RAID 1 Mirrored. Earlier this year both drives failed (one must have failed before the other one failed). We had to rebuild the entire machine and replace the drives (Two High Speed SATAs Western Digitals, 10000 RPM so according to Dell the drives spend a lot of time working) .
This morning were seeing error again on one drive. The drive checked out OK using Dells Hard Disk Diagnostics tool twice. We ran chchDsk and it found an error (See attached). Right now the system logs look clear.
But the bigger problem is the fact that I allocated 20GB to the C:\ drive initially which had about 8 or 9 GB free after the OS and core applications install. Then suddenly (like overnight), There was only like 4GB free. Today its down to 700MB. I have looked everywhere for log files, cache use, temp files, Microsoft update files etc and cant tell what's using so much space.
Could this be associated with a flaky Dell controller? Can anyone help?
