I have a two 1TB SATA drives configured in RAID 0. The partition is showing as 100% full despite only containing several hundred gigabytes of data. When Windows boots, chkdsk attempts to automatically run each time. I have had to walk away from the machine as the process appears to take several hours. When I return, the only output I can see is a message saying cannot write to the log file. I suspect this may be because there is no free space on the disk.

I have attempted to run chkdsk manually in Windows, but it appears to be locking up at 61%. Is there a way to free this 'used space' without having to resort to a wipe and format of the partition?

C:\Windows\system32>chkdsk E: /X /I
The type of the file system is NTFS.
Volume dismounted.  All opened handles to this volume are now invalid.

Your drive may still be corrupt even after running CHKDSK.

Have you ruled out the possibility of a simple infection? – Doopy Doo Feb 4 '12 at 11:37
Unfortunately, avast! is not reporting any infection. – Richard Feb 4 '12 at 12:10
One suggestion on a Microsoft Tech forum suggested running a defrag. Auslogics Disk Defrag is freezing on 61.20% the same as chkdsk. – Richard Feb 4 '12 at 12:11
