Subject: Hard drive power problemsOS: in betweenCPU/Ram: amd duron 900 / 320mb |
Comment: Last week I tried to turn on my pc and got nothing. It eventually came on but the hard drive did not power up. However when I unhook the IDE cable the hard drive powers up(and I know its not on backwards). I have even used a second hard drive and got the same results. Also, there isnt any video. I had an ECS k7s5a motherboard with an AMD Duron 900 processor. I thought perhaps something was fried on my motherboard so I bought a new one(ECS K7S5A-PRO), but it didnt work(or I wouldnt be posting). I have the same problem. The hard drive (both of them) work fine in another pc, my memory worked fine in another pc. Can anyone help me?

Reply: (edit)Numerous cables- including the new ones that came with the new MB. and the cables the hard drive's worked with in another pc. All the voltages are good in my power unit, not to mention I used another power source.

Reply: (edit)Hi This sounds like a power supply issue or faulty power wiring. A ide cable doesn't need to be in for a drive to power up. [well I don't know if that applies to drives over 40G] As far as the drives I seen - drives have power - they spin.

Reply: (edit)Hi I don't know really. But I thought you said both drives worked fine on other machines. Did you mean they used to work fine on other machines? Providing both drives are OK, I suggest there is a wiring problem (Red Yellow Black wires) going to the hard drive. It may be obvious or it may require pulling the power supply apart.

Reply: (edit)Hi Your computer is making it through post and your os is starting. The best tester is plugging in a working hard drive. Now if it doesn't spin up - power supply no good... ... game over. So you can measure voltage - you did this by testing the back of the plug whilst the computer was running. (I can see you have gone to some trouble before posting this question.) I haven't seen nor would there be any point to a power supply that runs the motherbaord but not the hard drives. [you have tried to see if the drive spins up without the ide cable connected? It should only take a few seconds, then kill the power.] It is curious as it will be the first time I've heard of a power suppy letting the motherboard run but not hard drive. When you computer is running, are you able to access the floppy and cd rom?

Reply: (edit)The floppy and cdrom have power. But since I am having so much trouble just getting the thing to start,I think I am going to just get a new power supply and if that doesnt work the cpu is the only thing left. Thanks fo all the feedback.

Reply: (edit)Hi Well I hope that sorts things out for you. I just like to see those on the forum - get to the bottom of problem, especially problems that defy how things should work. Most puzzling, your able to read cd rom and floppy ok (or you can hear cd spin up and floppy spin), yet hard drive won't power up. You didn't happen to mount it in its bay before testing? It may be a longer mounting screw than usual, touching some of the internal components in the drive.

Reply: (edit)I've got the same frickin problem!
I've got a drive that will read and boot from others machines, but in Machine A its native machine it will not boot.
I get video and it starts to search for the HD, but since the Hard drive won't power up I get a boot failure. The machine worked for several months, then once it got cold here, it just up and decided it wasn't going to boot at one point. Its a P4 2.4 w/ 512mb of ram and a 20 GB Western Digital. Its never given me problems til last month.
As I said the hard drive works in other PC's and when the IDE cable is yanked the drive powers right up. The ide cable works in other PC's.
Anyhelp would be great

Reply: (edit)Hi This thread continued at: http://www.computing.net/hardware/wwwboard/forum/19857.html My remarks/thoughs were probably more of a hinderance than helpful however. I had - for whatever reason (mostly very tired) not been very thorough/accurate reading the question and subsequent replies. In your situation would go through the checklist. Try the drive in the secondry ide channel A new 80 wire ide cable Remove power connections and cables to all but hard drive and see if it will boot. Try another good power supply.
