I pulled both of my drives out (I have a WD My Cloud Mirror 12TB, so I pulled out the two 6TB drives) and put them in a hard drive dock mount.
It pops up a bunch of local disks on Computer (“Local Disk H,” “Local Disk I,” “Local Disk J,” so forth). When I click them, it pops up message “You need to format the drive before you can use it.” I have already been using these drives and they have lots of files backed up on them, so there is no way I’m formatting them. If I exit out the message, another pops up that says “Not accessible. The volume does not contain a recognized file system. Make sure all drivers are loaded and volume is not corrupted.” I have been using the drive this whole time so it shouldn’t be corrupted.
Why is this happening? Does the WD box format the drives in a way that makes them unreadable to other mounts and computers?
The dock I have is the SIIG Cool Dual SATA to USB 2.0 Docking. Does anyone know if I need a particular Dock to work with WD drives?
All NAS drives tend to use Linux (or cut-down versions thereof like BusyBox) as their onboard OS, so their hard drives tend to be ext4 formatted to match for efficiency.
The MyCloud drives are formatting using an EXT4 LINUX format, they aren’t readable in native Windows. You would need to mount them in a LINUX OS or find a 3rd party program that will allow you to read a LINUX drive in Windows.
Move away from WD as soon as you can. I hope you can recover your data but beware, WD products are mote than below par when it comes to reliability. Find a different supplier as sson as possible.
