Two toasted hard drives. Help?! Make That Three!!!!! Hey guys, just fitted a hitachi deskstar 160 gb hard drive with my X800 into my machine (had the drive in for bout two months before this, ran fine). The rig ran but occasionally failed to boot up. Both my hard drives would not be detected in the bios. Then the 160 gb just stopped spinning. Had it replaced on waranty. Ran it in another machine to put files and docs that i needed. Fitted it back in to may machine and the drive stopped spinning. Whenever i connect it to either ide no drives are detected on that ide. System specs: P4 2.4 GHz 1024mb ram Seagate 40GB hard drive Asus IS7-E2 main board Gigabyte X800 (External power supply required) Teac DVD writer Dial modem pci Soundblaster Live 24bit 350 watt psu I suspect it may be my power supply but am not sure. Worried that i may land up toasting more drives. Edit: Bad news. Returned the drives to the store form which i got them. Also gave the guys my pc to run diagnostics. They tested the power supply and all was well. Fitted the new hitachi 160gb drive and the machine ran fine . They monitored the voltages as well as the amperage. In any case got a new 450 watt antec power supply (US$ 130). The guys at the store were satisfied with the setup and couldn"t see anything in my setup that could have toasted the two previous hard drives. Got home (no pc for 5 days, hence extremely satisfied after parting ways with the cash for the new power supply). Plugged it in and turned it........No ide drives detected (in bios) on the primary ide cable.i.e. Windows 40gb not detected and new 160gb drive not detected. Unplugged the new 160gb and rebooted . Everything works fine. The (third) 160gb not spinning up. Back to the store where the guys are absolutely baffled. Called the suppliers of the hitachi who i am sure at this moment (happy to give a 4th drive) are still scratching their heads with confusion. Any ideas???????? We're clutching at straws and thinking that may its the ide cables?????????? Please Help.
