Hi, so my 3tb external seagate drive wont turn on. No light, and the drive doesnt start. I took the internal hard drive out, plugged it in to my computer and the drive seems to be fine. I want to access the date on the drive, but it seems to be partitioned oddly and windows can't read it. Its supposed to be a 3tb, single partition drive thru the enclosure..... but for some reason its in 3 partitions when I mount the internal? Anyone know how to access this drive? (attached)
I'm considering buying another one just to slip this drive into an seeing if it works.

I am assuming that the controller handles the partition differently? Or is it possible my partitions are damaged? I only had one partition on the drive that I knew of?

It is partitioned oddly for compatibilty with Win XP, which can only read MBR partitioned drives and would otherwise be restricted to 2.2TB.
I don't have a 3TB to play with, so I'm only guessing that they use spanned volumes to make it look like a single 3TB disk in XP.
The drive seems to be fine, so it could just be the USB-SATA adapter in the enclosure that has failed, so getting another one might work. If you don't care about the data (because you have it backed up) then you could just repartition as a GPT disk (unless you need it to work with XP).
ps there is another complication that these drives seem to use 4k sectors and the bridge board may or may not provide 512b emulation (as I said I don't have a 3TB to play with so I'm only guessing). There doesn't seem to by any good info about the larger drives (and certainly not much from Seagate)

I dont have a backup..
So, Im looking for a way to read the files... installing linux right now to see if it can view the drive, otherwise maybe tomorrow ill buy the same drive and switch out the internal drives and hope it works.
Any other ideas?

PhotoRec is a bit misleading in that it recovers any files not just photos.
I keep backups so I don't really need it, but I tried it out and was able to recover files from a drive that had been reformatted a couple of times. I deliberately pulled the plug while the drive was writing to make the disk unreadable and Photorec was still able to recover files.
It would be nicer if you could mount the partitions and read the filesystem but I can't help with that, sorry.
Good move with Linux, sometimes it works where Windows can't. But you could just try a LiveCD rather than install.
