I have 4 Blue WD10EALS drives in a RAID5 enclosure. I can drag and drop files no problem and the WD Software says that the RAID has passed the tests.
However, I get an error that says that it cannot find the appropriate sector whenever I try to write a backup to these drives (have tried many times with different software). Again, the software passes the test.
So in windows, I tried to run chkdsk /r but it gets stuck and wont finish. So I used my Windows disk to enter command prompt in recovery mode to run chkdsk /r. It gets stuck on stage 4 and won’t complete. It has been sitting there for more than a day.
I think I was able to complete chkdsk /f but the backup still won’t write. I have a lot of data on the RAID so a reformat is not an option. What should I do?
So I took out one of the 4 drives to test by itself and the LifeGuard Diagnostics says there are too many bad sectors. I assume I should run chkdsk /r on these individually, but Windows sees them as unallocated and wants to initialize.
What should I do? I don’t want to loose the data or the RAID configuration.
Not sure if this was the cause of it all, but I seem to remember turning my computer off earlier this year when chkdsk was running on the RAID before it got to Windows.
Thanks, unfortunately, I don’t know of any tool including DOS that will chkdsk an unallocated drive. It looks like it is just one of the 4 and there is a rebuild feature on the RAID. So I may be able to buy a new disk and let it rebuild.
Do you know how I can chkdsk an unallocated drive? The disk will not be seen in the command prompt or recovery console. Perhaps Western Digital has a tool for this?
