Hello, I'm hoping someone can help me diagnose this problem. I have an HTPC (Asrock, intel i3, win 7) with several drives adding up to 15 TB. One of my drives, an internal 2 TB Hitachi is acting strange. Here's the behavior.

First here is what it does with no problems:
-Playing files on the drive presents no issues. I've never had any problems with the files that are stored on the drive.
-Writing files to drive is fine as well. I can transfer from any drive and write to the drive and everything is smooth. (Moving and writing mostly large files 4-8gb)
-I can move any file on this drive to google drive no problem.


The problems start when moving files from the Hitachi:

-Moving files from the Hitachi to another drive (internal or external) has been a headache
-Moving files allows some files to transfer smoothly and others to bog down the transfer. It will go from 50mb/s to 1.0 mb/s.
-On several occasions my computer just locks up and I'm forced to reboot.
-On other occasions the hard drive will disappear altogether.
- I was able to successfully move 85 of 100 large files. The other 15 all slow the transfer to a crawl, lock up my system, or make the HD disappear if I transfer them individually.
- Taking one of these files and copying and pasting (replicating it) it within the same drive also crashes the system. But I can move files (folder to folder) within the drive just fine.

Here's what I've tried:

-I changed SATA ports, SATA cable, and Power.
-I moved drive to an external enclosure and the problem is the same. It doesn't shut my system down or make HD disappear though. Just slows transfer to a crawl.
-I ran a chkdsk and it reported 0 errors.


I'm at a loss here. I have about 1.4 TB of data on the drive that I need to transfer, but with these errors and slow downs I'm afraid the data is stuck on that drive.

Any ideas what this could be?
 
MOVE-ing and COPY-ing a file are different procedures. The former doesn't actually touch the file's data, it only rewrites its folder entry.

You could try Bad Block Copy for Windows:
http://alter.org.ua/soft/win/bb_recover/

It keeps a log, so you can resume after an interruption.

Alternatively, you could try cloning the entire drive with ddrescue. It also keeps a log and allows you to resume after an interruption. Ddrescue understands how to work with bad media.

1: you should never move or cut & paste.

Always copy & paste
then verify the file is a good copy
Then you can go delete the original

In your case I would not delete the original; just get your data off the drive and then you can run a surface scan on the drive & check its health.

Lastly, your important files should never be stored on just 1 device. A disk dying should not be an issue and wouldn't be if you had backups. I realize at 15TB doing a backup now would be rather lengthy and expensive. It boils down to: "How valuable is your data?"
