How do I troubleshoot a slow hard drive?
My laptop is running very slow in the last days and sometimes when I turn it on, I get to that Windows 7 system repair screen. I tried to repair it and the repair failed due to a "I/O device error".
Trying to install Ubuntu is also hard (I had a dual boot system, but the filed windows repair mixed Grub up). It freezes after the "system requirements screen".
Because of this I/O error, I am guessing I have some problem in my HD.
How could I diagnose this? I would like to be sure that the HD is my problem before buying a new one.
EDIT: @Chopper3 I've read the FAQ and searched the kinds of topics in super user and server fault. I thought the right place was in server fault because there are a lot of topics and hardware and HDs there. Sorry if I was mistaken.
EDIT2: Sorry I forgot to mention, in the SMART diagnosis it it green and "few bad blocks"
EDIT3: Hey guys, I could do none of these, since My computer stopped working at all. Formatting and reinstalling didn't help, but running from liveCD works, so I think it might be HD. I will have to change it, since the computer is now unusable.
Tks for your help
