Running: Windows 7 Home Premium x64
I have a 3TB Seagate drive in a USB 2.0 enclosure. However, when the drive is powered up, Disk Management shows two physical disks - one at 2048GB and one at 746.5GB. I can use each of these disks normally, they'll format, accept new partitions, etc., but can find no way to tell Windows that they're both actually the same disk.
The first disk is identified by Windows as Disk 8 and Device Manager as ST3000DM 001-9YN166 USB Device (as expected)
The second disk is identified by Windows as Disk 8 and Device Manager as ST300DM 001-9YN166 LUN1 USB Device. This is the drive that I assume to be "fake". I'm vaguely aware of LUNs, but have only encountered them when working with VMs or clustered storage, never on a desktop and certainly not without Windows Server, which means I'm lacking the tools that I would usually use to manage clustered storage.
I supposed I could implement a work-around by creating a spanned volume, but since I just lost an impressive amount of data (see "Further Background"), I'm a little gun-shy of sketchy solutions.
Steps Tried Thus Far:
- Deleted the drivers entirely and re-attached the enclosure. Both drives installed as before.
- Used DiskPart to "Clear" the drives (hoping that it would also clear whatever header information is making the two-disk distinction". No joy, now they both just show up as uninitialized.
- Formatted the drives in every way that I could come up with, but as expected since I'm only able to touch one drive at a time, only that drive is affected.
The disk used to work perfectly under TrueCrypt, but when they dropped support I (stupidly) switched over to DiskCryptor (since Home Premium doesn't have BitLocker). I had a few file corruptions under DC, so I tried to decrypt the drive before searching for a more stable solution. The decryption failed and I lost 2.3TB (and about 4 years) of data. As part of the decryption process, DC created two drives - one for the encrypted data and one of the data that had already been decrypted.
After trying with no success whatsoever to recover the data, I gave up and wiped the drive (after many shots of vodka). However, even after the wipe I'm still left with two drives and thus far haven't found a way to combine them back into a single 3TB drive as it once was. (Though, again, without any of the data. Lesson: don't used DiskCryptor if you like your 1s and 0s.)
As always, any suggestions are greatly appreciated.
