Hello,

I have a Seagate Barracuda 2TB HDD that is technically working fine, but it is running some kind of internal process that takes up 100% of its attention and the actual data output is averaging about 800 kbps in pulsating spurts from 0 to about 2.5 MBps, about 4 or 5 seconds between. It has been my main storage SATA drive for a couple of years, until this started happening on Sunday. Since then I have tried the drive in 2 other different computers, one a PC, one a Mac, and they all show it as 100% active (in task manager performance) but with tiny transfer. I have tried it as USB or SATA, I have changed drive letter, and I have rebooted the computers and the drive itself a number of times, and I get the problem instantly each time. As soon as it shows up, it's cranking away at something. I ran a dskchk /f scan and it did fix a couple of errors but hasn't changed anything. I'm trying to get everything off it but it will take about 20 years at this rate. Interestingly enough the data all seems to be intact except for a couple of files which seem corrupted.

What would you do next?

Best regards,

Matt

Your only realistic DIY avenue is to clone the drive with HDDSuperClone, and then hope that you can recover your data from the clone.

That said, be prepared for the drive to fail completely at any time.

I expect that CrystalDiskInfo will report numerous reallocated, pending or uncorrectable sectors.
