I have two external Seagate Goflex 3TB drives that were working fine and then one day when I moved them to another computer they became unrecognizable. They were on a Mac, then I brought them over to an Imac and they do not work. The drives models are ST3000DM001. I'm trying to get the data off of them so I can back them up to another hard drive. I will then re-format these drives and then re-import the data. I am trying to fix these with a PC. I feel more comfortable working on it. I plugged in the drives into my Windows 7 PC, and my Windows XP Laptop, I get the same issue. The device drivers install properly and windows says that the devices are ready to use. I go into my computer and do not see them. In the device manager they are there and there are no exclamation points on them. I can even see them in disk management but cannot access the drives from there.
I believe the problem is that the drives all the sudden thing they are raid. I burned Knopix to cd and they show as raid in there. I came to this conclusion after reading this thread on a Linux forum. I really know nothing about Linux. http://ubuntuforums....d.php?t=1267663
after further searching, I'm not sure this is related to a raid error. I ran something called testdisk and I didn't get any errors in the partition. I don't know if I really used the program properly, but I believe I did. I'm at a loss.
Can you guide me a bit on providing you with sector 0's information?
To note... I made the same post on the Ubuntu Forums, I was hoping to learn a bit more about Knoppix because I thought it was the tool to use for this specific situation. I made a huge post of information. I'm not sure if it has what you need, but maybe some of it will be of help to you.
AFAICT, your other post is telling us that the drive has been partitioned in GPT mode with an HFS+ partition. Therefore we don't need to see sector 0. It also explains why Windows doesn't recognise the file system.
I bit the bullet and got macdrive 9 pro. I really want get this data back. Windows explorer sees the drive, but when I try to access it, I get this error "H:\ is not accessible. The disc structure is corrupted and unreadable"
