MarkThanks!I think you mean ddrescue? I have been running it for a few days and getting lots of errors.Any suggestions on how to cool the usb drive with the errors. I have it flat on a cold large faux granite desk surface which is very cold to the touch. But the drive is still very warm.
GNU ddrescue 1.17

Copying non-tried blocks...On Sun, Dec 20, 2015 at 6:48 PM, George Toft <george@georgetoft.com> wrote:There is a special version of dd that will retry on bad sectors and try to formulate a best guess for the bad sector. I've used it with some success - took about 2 weeks to recover a 300GB drive. I also had to keep it refrigerated.

There is an application called test disk that might be handy for data recovery. But this looks like your drive is in bad shape.

MarkThanks!Any thoughts on how I can fix this drive, or do I need to get a new one? What is the best way to copy the contents of the drive with these errors to a new drive?I noticed this in the attributes section of smartctl -I tried running smartctl on the device, (which is now plugged into a usb 3.0 port on my laptop) and got this error after a few testsI have a 2 TB WD USB drive that I formated with NTFS. I have a rather extensive movie/TV library on it for my plex media server, and I am getting read errors. I hope I haven't lost all of that data! It has been attached to one of my Netgear wireless access points, hence the need for NTFS.fdisk -l gives for the drive
