Deleted RAID 1 Volume - Need Data
Next, I popped the remaining 2 TB drive out, leaving only the 5 TB drive. I verified all files were accessible on the 5 TB drive and copied even more data to it. Later, I went to access the data, but most of it was inaccessible. Then I rebooted the PC, and the 5 TB drive was completely inaccessible and I received a message that I must format the drive to use it.
Thinking that perhaps Windows didn't like the new drive utilizing the same logical drive letter as my previous RAID volume, I used Disk Manager to delete both missing drives using the Delete Volume option.
The 5 TB drive still shows as an unformatted disk. Inserting either of the 2 TB drives also shows as a "Foriegn" disk. Placing them in a USB cradle and connecting to a different PC also shows as an unformatted disk.
What gives? I thought I could take a drive out of a Windows RAID 1 configuration and access the data as if it were a single disk. These were not encrypted, and the drives were not physically connected when I selected Delete Volume, so the data on them cannot have been altered.
How do I get the data back? Preferably on the 5 TB drive, but I'd settle for the 2 TB RAID if that's much easier. What can explain how I lost access to the data on the 5 TB drive when I made no changes?
