Dead Seagate SATA Hard disk drive

daisan · 06-15-2005, 07:03 AM

Hi,

Can anyone please tell me whether anyone have experienced dead hard disk drives because of thunder? My two SATA hard disk drives are not being detected any more.

One of my TVs were also affected by that thunder-storm.

I'd really appreciate if you could shed some light on this issue.

Thanks!

Wow, never heard of that happening before, though irregular mains supplys can do strange things. If your PC was on, when you had some sort of electricity attack then I suppose it is possible. Generally speaking your PC powersupply 'should' safely regulate any overvotages or spikes. They have to be fairly stable and this is one reason why switch-mode units are used...

So when you boot the PC you don't see any drives detected. If you enter the bios setup and manually scan for disk drives, do you get any detetected? Do they spin up at all? you can put your hand on them and feel them vibrate slightly to check. Have you checked the voltage rails on your powersupply? it may be that this is knackered, rather than your disks. it is worth chekcing the supply rails with a VOM (volt ohm meter) ... or the modern equivalent.

... More info needed really

No, my PC wasn't ON, although it was plugged in and the phone line was plugged in too. The UPS is working fine, PC can boot from the DVD-ROM, but it just can't find the hard disks.

I haven't scanned manually by entering BIOS yet, will do it later today and will get back to you. However, the problem is a weird one and I've never heard anyone facing such a problem before.

Thanks for your time though :)
