Windows 7: InTheMarketFor New extHDD - concerns about eSATA vs eSATA2/3

InTheMarketFor New extHDD - concerns about eSATA vs eSATA2/3

I have been having problems getting my very old external HDD to connect via eSATA (cable is eSATA3 @6GB/s) to my desktop. Same problems whether it is the front panel of the case's built in eSATA, or the mobo's. I tried it in my fiance's desktop, and it works perfectly every time.

I want to buy a new ext HDD anyway, but this does have me concerned and confused.

SATA/eSATA things should all be backwards compatible, correct? Well, follow me here...
The case came with an eSATA port on the front panel. I saw that this had a SATAI cable coming out of it. I replaced that with one of many cool UV lime green SATAIII cables, connecting to SATAIII headers on the mobo.
Also, the ext HDD (Acomdata 1TB PureDrive) is very old, so probably only SATAI connection in there, and an eSATAI port. The cable from this to the desktop port now is also eSATAIII.

Since this was happening on my brand new OS install here, I doubt it could be a Windows 7 issue. Then again, I plugged it into my fiance's rig -1 yr old, Win 7, untampered eSATA connections- and everything was perfectly fine.

Any ideas? Could have replacing the SATA cable from the desktop's port to the mobo have messed things up? Is there something that might be off in Windows 7 or my BIOS??? I don't want to go buy a new SATAIII/eSATAIII external only to find that it will have the same problems. =/
