Can't activate dynamic disk

Question

For some reason I can't activate a dynamic disk connected to my PC via a USB hard disk enclosure. It has activated previously without any problems.

When I check the event logs, I get this message every time I try to activate the disk: dmio: Harddisk2 write error at block 2930277167: status 0xc0000015

Answer 1

Microsoft is now enforcing the no-USB policy for Dynamic Disks.

If it is a single disk dynamic disk (not spanned or striped to another disk or set of disks), you MAY be able to convert it to a Basic Disk.

Answer 2

I ran the manufacturers to test for errors, but it found none. I still can't access the disk, but I was able to use this tool to recover all of my data. I suspect the problem was caused by a dirty shutdown in Windows.

Answer 3

I'd run SpinRite on it to clear up any errors or bad sectors. I've saved several disks by using it, although I never use bad disks in a production environment after they've started giving errors.

Answer 4

I just ended up reformatting the drive in the end
