Slow USB transfer rates (60kb p/s) External HDD --> Internal HDD

drfrostbyte · 03-22-2011, 03:43 PM

I'm running Ubuntu 10.10

So, after I accidentally unplugged my external HDD WD Elements 2 TB, it has issues being recognized, mounting, and HORRIBLY slow file transfer rates. My HDD is a sata 500G harddrive (7200rpm). I was originally getting 20 MB p/s transfer rates, and it worked fine before yesterday. It's being quite unresponsive. I have music that I purchased on itunes that I put on it, so I could wipe my desktop and put Debian on with the intent to make another backup of some sort.

Have you tried it on another PC? Do you have external power connected (if it has it)? whats the output of 'dmesg|tail' after you plug it in?

edit: I'm assuming its a 3.5" 500G SATA inside an enclosure.
edit2: Looks like you have two drives, which one is giving you the problem?

The internal harddrive works fine because I transfered files to a USB to test it, it is definitely the external

Normally I'd say read the smart values but the controller 99% of the time doesn't implement it. I'd recommend plugging it into your PC without the controller/enclosure and see if you have the same problem.

I'd run a file system check (on external hardrive) using gparted with external drive plugged in but unmounted before doing a check. Probably scrambled due to improper unmount.
