harddisk sometimes working sometimes not

[tryitn1]

hi,
i ran the most scan and read bad sectors on my IDE Barracuda seagate 160GB harddisk. I didn't get any errors. But sometimes why harddisk doesn't get detected in BIOS. When i bootup with floppy it still doesn't show up in the device menu.

Now i power down the computer 2 or 3 times and sometimes give a very small tap on the side of the harddisk (this i got from experience or a very small shake) and it would boot up fine showing in BIOS and in mhdd.

Can you suggest the source of this problem ? This has been happening over the last 7 -8 months around 3 - 4times. I never hard any other problems with this harddisk.

I aslo tried hdat2. I still get the same error.


Thanks
terry

The disk is dead and it's getting tired coming back from the grave.

Get a new disk immediately. Do not attempt to salvage a $60 disk.

What does osculation mean?
