SCSI server hard disk without a power plug

[imported_MooGoo]

I have a SCSI Seagate Cheeta 36gig 10K server hard disk. It has an 80pin (I believe) connector on the back and no power plug. I assume it gets its power from the SCSI cable...

So I went to a local computer shop and I picked up a cable that fits, the guy also gave me for free a PCI card that had the same connector on the other end. He said he did not know if it worked, thats why it was free.

So I put it in my computer and booted up and windows detected it and installed software for it, and it turned up in the device manager as a SCSI controller. So far so good.

However, it doesn't seem like that hard drive itself is powering up, I feel no vibrations from it and no sound, and of course it is not picked up by windows.

Now this hard disk gets its power from the SCSI cable itself, but I serioulsy doubt that the PCI card its hooked up to can provide enough power for it, it has no extra power connectors on it. I've seen some fairly expensive 80pin to 68pin (or somthing) adapters with a power conenctor on them. But whats the point of having a full 80pin plug on the SCSI PCI card itself if it cannot provide the power? What am I doing wrong?

SCA-80 requires a backplane OR an adapter to work with 68pin wide devices.

An adapter will have a power connector (frequently called a "molex"), a 68pin female connector (goes to your UW SCSI cable), the SCA-80 pin connector that plugs into the drive. Some have a terminator, some do not. On ones that do not provide termination, you must provide termination at the end of your UW cable!

Yes, but I have a PCI card that has 2 SCA-80 connectors on it. Yet there are no molex connectors on the card. Is it possible for a card being powerd by nothing but the PCI bus to provide enough power for a hard disk?

In a word, no, that scsi card prolly came out of a server where it was connected to a powered backplane or enclosure, your going to need a 80pin to 80pin adptor w/ power to get your drive working w/ that scsi card or a new scsi card and a 68pin to 80pin adaptor.

would this work?

That is what the adapter you need looks like. But your drive requires an LVD compatible adapter. I have bought several from yoozinha (or something like that) on eBay and they work very well. He was still selling them on there last I checked and for about half what I paid for mine...
