Hey guys, I need your help.
I have a 3TB Toshiba internal HDD which seems to be dying (SMART says Reallocated Sectors Count is very bad).
The thing is, nothing I tried does find Bad Sectors (CHKDSK, HDD Regenerator, ...) and my data seems to be accessible. The problem, however, if I try to copy files off of it it works unbearably slow.
When the HDD tries to access the (I suppose) bad sectors the reading speed goes down to less than 500KB/s, while at other times it seems to be fine and the file starts copying at 100MB/s. I have had a backup running overnight, but it only managed to get like 300GB of the 2700GB, so I'm looking for another angle. Also, when the HDD is accessed for a scan or copy or anything, the usage goes up to 100% immediately.
In Windows Task Manager it then says
- Code:
Active Time: 100%
and jumps between
Average response time: 2000ish ms
Read speed: 500ishKB/s
and
Average response time: 0ms
Read speed: 0KB/s
I've tried 'Roadkills Unstoppable Copier' that apparently can copy undamaged files first and so on, but it doesn't think that any of my files are damaged, it starts copying just as everything else and then just goes down with the speed to take forever.
What I don't understand is why there are apparently bad sectors, but nothing does see them, the HDD just totally dives in performance when these sectors come up. That's what I guess at least. Am I overlooking something?
What's the best way to salvage my data? I assume I will send that drive back for warranty after I have my data secured.
Thanks for the help.
Edit: I just finished copying a video (first 30% of the file took like 10s to copy, last 70% took more than 10mins or so) to another drive. It opens and plays just fine.
