I am running an Acer Aspire ... how do I check my BIOS to see if my hard drive is working? I say this because recently my computer gives me "Disk read error" and I want to see if my hardd drive still works. Thank you.

That's probably not only the way you would want to check whether a hard drive correctly works. Why not ask about the real problem you're facing and let those who answer figure out where to look? :) How exactly did you meet that error in the first place? –  slhck Oct 6 '12 at 20:40
    
Slow computer. Tried turning it off. Froze on shutdown. Did a cold poweroff. Turned it on again. Windows load to blackscreen. Turned it off and on again...that error. –  naknode Oct 6 '12 at 20:43
    
Can you give us system specs? –  user88311 Oct 6 '12 at 20:51
    
You'll have to enter the BIOS "Setup" program - press a keyboard key (could be Esc, Del or F1, depends on BIOS version) after a reset. Depending on the BIOS version, it might display the detected drives on the main screen, or you may have to drill down a few menu selections. There may be some configuration options, and if you're lucky, it can run a few S.M.A.R.T. tests on the HDD. –  sawdust Oct 6 '12 at 21:07

The best way to do this is to read the SMART data from your HDD to see whats wrong with it. This link provides a good explanation on the SMART technology. If you have access to your OS, you can use many programs to read SMART data, like HD Tune.
