Possible harddrive issues?

[Benvo]

Hey,

Basically may just be something simple but im unsure, i have 4 harddrives in my system, 2 full, 1 for random storage. One 2tb partitioned, 100 GBish for system (win 7 64 bit) Rest for use as want, generally to store dwnloads on etc... Now computers beens slow on start up for a while, assumed this was because of the amount of data i have on harddrives, and programs that auto start?

And today i went to check a 360 image in abgx and the read spead was like 0.8-3mbs when usually up to 100. Copied to another drive, image read fine at usual rate. Did try it again later and read fine, so maybe just because it was close to start up or ?

Also just extracted a 4 gig file through winrar to the harddrive which i believe may be playing up, took around 10-12 mins, when its usually alot quicker than that!

Am i facing issues or is it just random? Harddrive is just over a year old (think its got 2 year warranty, but i do have alot of stuff on it, that prob wouldnt wanna rehome unless it was last resort)

Willing to to do anything needed, just unsure where to start?

Many Thanks

Have you defragged it and ran chkdsk?

[Benvo]

Doesn't need defragging according to win7 defrag says 0%. Chkdsk in properties?

Chkdsk in properties?

Yes, you can run it from there. Properties > Tools > Error Checking. You can also run it from a command prompt.

go into hard drive properties and make sure its not checked under general

allow files on this drive to have a contents indexed in addition to file properties

this can slow down your drive on start up

hard drives normal fail with a read write error.
but the more you fill it up the slower it will go.
