I've run into a strange problem. A few months ago I set up a RAID 5 array on a Highpoint 2720 card. I went to copy files to the array the other day and I couldn't because the volume was full. I have 5 3TB drives, so ~12 TB total space and there's < 4 TB of data on the array.
I ran chkdsk without the auto-fix option and it gives me what appear to be the correct numbers for space used, but if I try to use it to fix the problem it never finishes. I've let it run for over 48 hours, but it just seems to get stuck.
Are there any better tools for fixing file system issues on a RAID volume?
