Hard drive failure

[rnix]

Yeah, well i turnt my computer on about a week ago and it said "Hard Drive Failut - Dell reccomends you make a backup" then it restarted by itself :S so i turnt it back on it did the exact same, tried to turn it on again. Doesnt even turn on anymore :S

Cant send it back to dell. Just was gonna buy a new hard drive but i cant find out the hd size.

Anyone know how big the harddrive is in the Dell Inspirion 530.
Thanks

Normal dekstop size i'd assume; 3.5"
