Not sure if this is an "internal" or an "external" (more like internal-made-external) but here goes.
I had a computer that died a couple years ago. I had two hard drives installed in it. I just bought a Coolgear HDD to USB adapter module and on drive #1 (Seagate 120GB 3.5" IDE) it worked great! As soon as I plugged it in and turned it on, a window popped open and the drive showed up just like any other and I could access everything with full functionality. It was great, I got back a bunch of files I thought were lost for good.
On drive #2 (Maxtor 40GB 3.5" IDE) when I turn the module on, the drive spins up and doesn't make any problematic noises (nothing to tell me the drive doesn't work) but nothing happens. It never shows up on the computer. I get the feeling this drive should work but for some reason the computer isn't seeing it. Any ideas? Is there any way to "ping" a specific USB port or anything like that?
I have tried putting the jumper in every possible position (except removing it entirely, it doesn't really show that as an option).
