I have a Seagate 3 TB USB 3.0 hard drive that suddenly went bad AGAIN after a few months of being good after reformatting. I tried checkdisk in Command Mode and it said this is a RAW file system, I go to Computer Management and it says the drive is NTFS and healthy. I tried to copy as much off of it as I could for a few hours but didn't get everything. I took some camera snapshots of what I still have yet to copy, (doesn't work on CRT monitors btw.)
Everytime I plug it in now, I get Autoplay locking up the drive and the HDD icon lost it's usual color & is now white with a blue ribbon, and I also get a prompt to "scan the hard drive for errors, or not?" The first scan it found 34 errors and it took hours, then told me I need to format it. Now I'm having a very hard time accessing the drive to copy anything off of it, it keeps crashing and locking up Windows Explorer. I have to unplug the drive to get Windows back.
When I had this problem months ago it was a USB driver issue, I had to download and install a very specific USB driver for this hard drive to get it to work temporarily before reformatting. I'll have to see if I can find that info again somewhere.
The guy at Staples told me that Seagate hard drives from 3 TB to 4 TB had a high return rate of 17%. This is my 3rd or 4th hard drive failure of this size. He said the Seagate 5 TB drives had half the return rate. He suggested another brand like Hitachi that had a much lower return rate of around 2%. I don't know what to get in the Columbus Day sales next week, but I'm gonna start looking around now.
