slow hard disk

[Benjamin Biron]

Has it been like this since the first time you booted fedora?

I improperly powered off a couple days ago and when I rebooted in 
fedora, everything was extremely slow and it was apparent the hardrive 
was the bottleneck (Opening mozilla made the HD churn for around 1 
minute on a dual MP 1800 with 1 gig of ram). I tried a bunch of things 
to solve it and gave up. I was so frustrated with the time it took to 
boot I just powered off during boot. When I powered back on, everything 
magically came back to normal.

Btw, I'm not necessarily suggesting you do this, I'm just stating that I 
too observed odd behavior relating to HD performance. Just for the 
record, I have 1 Western Digital (120 Gig) drive and 1 IBM Deskstar (80 
Gig) drive. Also, I had odd performance problems with the Western 
Digital in anything other than cable select. Maybe you could try to put 
your drive in cable select?

Good luck and sorry I can't be of more help.
