My 2TB Seagate internal is showing large numbers of reallocated sectors (64568 and increasing) and massive ammounts of seek errors (2,899,327,467,254 !!!) in the SMART data. Both numbers are consistently increasing everytime I try to read from the disk. Disk transfer speed has slowed to a crawl of about 300 KB/s. I can get about 15 MB/s of transfer speed for the first 50 MB or so of data I read from it, but after that the read speed slows to around 300 KB/s. If I wait a bit for the disk to recover, I can get a small burst of transfer again. At this rate, my disk would completely die before I could backup the ~80 GB of data I really need from it. What is the best way to backup such a drive before it fails?

IMO you may have waited to long, you could try adding a drive to the system then drag and drop.  I would say a prayer while doing so!


Honesty & Integrity Above All!

I think the seek errors are causing the sectors to be reallocated. Is there a way to stop it from reallocating sectors so I can get a decent transfer speed? What happens when the disk runs out of spare sectors?

Do I have to send it to Segate or a backup service to dump data off the platters, or is there another way?

How important is the data that is stored on the drive?  I have used Kroll Ontrack previously to have data recovered for work, but I never saw a charge of less than $1,000.

 

Copy the data off in order of importance to a new drive is your best bet.
