PC won't power up after installing a new hard drive

[mister_to_you]

Hi,

I recently purchased a new Maxtor Diamondmax 10 300Gb HD to act as a slave to my Maxtor Diamondmax 9 160Gb HD.

The Jumper is correct and all is connected, but when I power up the PC Nothing happens. There's no power.

If I connect just the the new 300GB HD then it works and it works in my old PC as a slave to a Maxtor 4GB HD.

Any Ideas?

Thanks

No power?
Check your BIOS

might need a p.s. that supplies more amps. amd's are extremely power hungry. 500 to 600 watt units are getting common fo a reason.

You might want to double check all your electrical connections.I seem to be clumsy at times and bump stuff that gets disconnected. Make sure everything is hooked up nice and tight.

Your old drive most likely is jumped to slave drive too. That's why one of them will work, but not both of them.

Incorrect jumper should not cause total failure to power up.

Isolate problem by completely disconnecting data cables to both drives, connect power to each, test. If this does not work, and since the new drive works by itself, this would indicate you need more power.

If this does work, next set both drives to Master or Standalone, place on seperate IDE channels, (disconnect CD and use that cable, no other drives but HDs on each cable), and test. This is to isolate an incompatibility between drives.

Are you saying the new drive recognizes correctly by itself, with the jumper set to Slave? This should not work, or have you changed the jumper? Do you have Cable Select cables?

Are you absolutlely certain the new drive was not temporarily placed in such a way as to cause a short? This will sometimes cause a failure to power up, will sometimes activate the smoke chips. Smoke chips are a one-shot deal.

Yup I've seen some scary things here. A small percntage of People bring in the PC for a problem and we see really strange things. Drive hanging on the power and Ribbon cable no screws at all. Sheet metal screws, Screws to long and digging into the drives circuit board. And of course the securely mounted new Motherboard. I know it is secure beause it is bolted down tight to the metal of the case without standoffs, It'll never move.
