I'm using Drivepool on my Windows 8 PC and currently have 4 2TB WD hard drives exclusively for data storage, and set up in 'duplicate' mode. Windows, and Stablebit Scanner are both telling me that one drive could die any moment, and another is on the way out.
Thankfully, they're both still under warranty, and I've got an RMA from Western Digital, but I don't know how to go about taking out the drives and sending off (before waiting about 10 days to get replacements). Obviously I don't want to lose any data!
All advice welcome. Thanks.
