2 TB HDD is suddenly extremely slow to backup or copy files to other drives in a Win 10 system. Using a recovery utility (DDRescue-GUI) shows an ETA of 200-800 days. Advice is appreciated!

2 TB HDD is suddenly extremely slow to backup or copy files to other drives in a Win 10 system. Using a recovery utility (DDRescue-GUI) shows an ETA of 200-800 days. Advice is appreciated!

Hello, I have a Toshiba DT01ACA200 2TB HDD of substantial age (5+ years) in my Win10 desktop PC, and I've been using it primarily for media storage. My system can run AAA games reasonably well, in case gauging performance is important. This past weekend, my scheduled local backup stalled midway and I've been attempting to troubleshoot it since. Due to a critical mistake by me misunderstanding the depth of the issue and poor backup practices, I no longer have a backup image available for this drive.

I would like to copy the data on this drive to a stable drive; however, most attempts to copy large batches of files have resulted in a stall. The destination drive appears fully functional.

Some information:

  • By "stall", I mean that read rates plummeted from XXX MB/s at the start to 20 kB/s. It is at 11 kB/s and 65 kB/s most of the time. As of me writing this, the Current Read Rate is fluctuating between 11 kB/s and 130 kB/s. This measurement originates from the Performance tab under the Win10 Task Manager and DDRescue-GUI backup process.
  • Any activity that requires usage of the drive is not very responsive when I am copying or backing up.
  • I haven't noticed any issues watching 4K media from the drive or writing media to the drive unless I'm copying or backing up something from the drive. Even media files that stall when I try to copy them are watchable with no issues.
  • I have attempted to use Teracopy and Roadkil's Unstoppable Copier, but these utilities stall on the same files. I'm currently running DDRescue-GUI and recovering the drive has an ETA of 200-800 days.
  • Error Checking through the drive's Properties menu does not indicate any issues. DDRescue-GUI has not found any bad sectors. Current progress on recovery is 10% with an ETA of 200-800 days.
  • I'm including a couple of snapshots in case it helps with diagnosis:
