Hai,
This is sandeep kumar. I am having problem with my hard disk which is seagate. Till day before yesterday it was working fine. But today it is not even detecting. I am in confusion what to do. I don't know what may be the problem in tha disk. So can you please suggest me what may be the basic problem so that I couls rectify it without taking it to the hardware shop. Just tell me what may be the besic hard disk problem. And I never fell it down or or not even it damaged somewhere... please help me...

If it was working OK and then stopped then chances are that you have a hardware problem and you may need to service the drive. However, some basic things to check (long shot but worth a try):

- Check to make sure the power connector is seated properly
- Check to make sure you are receiving power to the drive. Replace the power connector with another unused connector if you have to
- Check the BIOS to make sure it is set to auto detect your drive
- Check your IDE cable to make sure it is connected
- Check your jumper on the cable in case by sheer bad luck it slipped and fell out (highly unlikely though)

Basically pretend that you're installing a new hard drive and go through the motions of setting it up from scratch and don't assume anything.

Good luck

Casey

Are you getting any errors messages?

Hai, once again.
I have tried all the steps which you have given me sir cajalat. Anyway thank you very much sir.I am not getting any error messages sir. Any more sujjestions from you are side. It's not at all detecting the harddisk. And it's giving some sound which doesn't matter I think bcoz it's a sound which is coming very silently if ve keen observer it... any way thanks sirs...

I have a problem sometimes I loose two disks on explorer, they are both connected to the second controler. I get them back by going to Control Panel / System / hardware / Device Manager / IDE ATA/ATAPI controlers / secondary IDE Cannel then right click choose uninstall, after done restart PC and let it find and install drivers for the drive. I've done this a couple times in the past with good results.
