My computer recently started to stutter a bit lately and one of my Seagate hard drive became really slow when opening folders, running programs from the drive etc., ultimately ending with the computer restarting. Upon reboot it went right into the Windows 10 chkdisk on boot. It was very slow as well, so I ended up leaving it over the night. Before I left the computer I saw there was a bad sector mentioned. Next day I was a bit more relieved when I saw the logon screen, and I found the hard drive in Windows explorer. First thing I did was to start copying everything, but the transfer speed is very slow. It jumps to between 1 and 3 mbps, until it drops down to 0 again. In one day I was able to copy around 20 gb.
With the hard drive being this slow I guess it's a sign of the drive slowly failing. I checked the computer management, and it seems the disk has changed from Basic to Dynamic for some reason I don't know after running chkdsk.
I would appreciate some advice on what's the best idea right now. My first thought is to leave the computer on and just keep copying files. Or is it better to take breaks every now and then? And with the disk being 1.8 TB and with this speed it will probably take a month until everything is copied, and I'm a bit afraid the drive will fail before it's completed. And will the heat produced from the HDD possibly have a bad impact on its already failing condition? Or is there better ways to take backup, or are there other possible causes for the hard drive being slow? I have tried swapping cables and hard drives to check.
