New scsi adapter won't detect my HD...

I recently upgraded my Diamond Fireport 40 SCSI adapter to an Adaptec 29160N adapter so I could run Windows XP. Upon swapping in the new controller, it does not recognize the only device I have connected to it - an Atlas 10k (original version) HD. When scanning for SCSI devices, the adapter returns a "Time-out failure during SCSI Inquiry Command!" error and never finds the drive.

I have a powered 80pin->60pin adapter with a bult in active terminator. I've tried my own rounded SCSI cable as well as the included terminated cable.

Anyone have any ideas on what the problem might be?
 
Possibly the wrong type of 68 to 80 pin adapter. Perhaps your adapter is designed for an LVD drive and the Atlas isn't an LVD drive or vice versa.
 
How can I tell if the adapter is LVD? I know the drive is, but looking at the adapter, I can't seem to tell...
 
Okay, more info. The adapter I had been using with the Fireport has a part number of 806850AT, and I believe I got it from Hypermicro. Looking through their site, they don't seem to show part numbers...

I found another adapter that I had lying around, and with this one, the SCSI adapter identifies the drive upon scan. But, it shows it at a 17GB drive rather than the 18.2GB that it really is. Any idea why this would be? Can I assume this SCA adapter is an LVD adapter simply because the SCSI adapter can see it?
 
If it is the correct SCA adaptor then it will identify the drive as a U160 or U80 drive. If it is forced into SE mode by having the wrong adaptor or terminator, then it will identify as U40. It will show the formatted capacity in true GB, not the hard drive industry rated capacity.

Does your hypermicro adapter have both a 50 and 68 pin interface, as pictured:

Here?

Probably not an lvd adapter if it can connect to either 50 or 68 pin cables. If the card is recognizing the drive with the other adapter, you should be good to go.

The drive is being identified as U40. 🙁 Why would this adapter allow it to be recognized incorrectly, while the other wouldn't allow it to be recognized at all?

No, it only has the 68pin interface. Not sure if this adapter is correct or not - see my last message...
 
If the adaptor has term power jumper, that would tell you it is SE for sure. Controller cards tell what type interface is connected to it by the voltages it detects on the line. LVD is low voltage differential and the controller needs to detect an LVD terminator and the convertor needs to be an LVD rated convertor. My non LVD adaptors have a yellow resistor soldered to it, that the LVD do not have. THe drive itself could also have jumpers on it forcing SE mode.
 
If it was running on a Diamonf Fireport, I asure you it WAS NOT LVD...

AS others said, check to see if that card has a non-lvd channel
