My brother has a problem with his external hard drive (Western Digital 500 GB, NTFS file system), he can't read the stuff on it with his Windows 7 PC, however I think Windows recognizes it as he is adviced to format it.

I told him I will show him the power of Linux (backtrack 5) and get his data back before we format it. The thing is, I have been trying since for a week and I think I'm not going anywhere.

This is what I get in /var/log/messages when I plug it in:

And it continues reset again and again.

Could you help me?

Windows 7 can't read the data on the drive. Windows 7 just suggests formatting it. Linux can't read the data on the drive. Sounds like the drive is dead. I'm willing to bet that if you tried to format it, the format process would fail. –  Bon Gart Jun 10 '12 at 15:08
    
Or maybe USB board is fried... HDD may (or may not) work if connected directly to SATA. At least with my experience it is more than often worth to try, some drives (broken ones) seem to work better when connected to real SATA. I think it has something to do with better interface reset/recovery from error. Also if drive is broken but is recognized with SATA try to read it backwards... –  Sampo Sarrala Jun 11 '12 at 0:28
