Very slow read and write speed

[shantanu18]

I am using maxtor 80GB hard disk. My problem is it takes too many time to read and write. it slow the hole computer. Even it takes too many times to open drive, folder and when loading bios(checking component at startup). Data transfer speed is now in kbytes. I deleted all the partition and repartitioned, but no luck. I checked hdd using partition magic 8.0. surprisingly no error found. Same result for windows utility also. What the problem is this? what should i do?
Note: I tried my hdd in another computer and same result. So problem is in HDD. i also made low level formating to fix the error.
it took all most 2 hours to setup windows xp. my ram is 512mb.
Thanks is advance.

the drive is dying, degraded head/smart error
leave the drive to thrash and continue with a new drive.
