Lately my computer has been having real trouble playing videos
(extremely jerky), and even scrolling through a long list of files in
a directory in windows explorer (jerky scrolling). I ran some tests
using HD Tune and HD Tach to see if it was a hard drive issue, and low
and behold the read speed is terrible. I am getting a maximum read
rate of about 4MB/Sec. My drive is a 120GB Maxtor 4R120LO. Is there
anything I can do to fix this? I defragged it but no difference. Can
it be saved?

Thanks
Marcus
