Finally completed mounting everything inside. Unit looks good, sounds good and now for burn-in.
Already I'm running into troubles.
Cabling wise my 50 pin do D-sub 25 adapter is good with no breaks. It was wired from this daigram:
However even with a terminator fitted between the internal cable and the drive no system can detect it.
I pulled the harness out of a Sun 411 enclosure and tried that to ensure it was the cable. Sure enough even without a terminator I had computers detecting it. :?:
Second problem is a bit more fatal. The drive either needs a LLF pretty badly or the HDA has failed. So the moment you poke at it it starts to constantly reseek with the odd moment it actually reads or writes.
Edited: I managed to format the drive. Windows was being cranky so I pulled out the Mainstreet and tried it instead. It formatted and mounted after selecting the low-level format option. After I do another format with HD SC setup (Unlike Drive Setup, HD SC setup will fail a drive at even the slightest hint of a problem) I'll throw Snooper's looped disk testing at it and see what happens in a few hours.
Okay, so back to problem #1 again. The cable.
electricially it's intact but something isn't getting across. Any trimmed ground lines seen are still getting grounded at the drive. There's at least four ground lines that are linked directly from the host system to the drive. Pin 1 is shield ground for the connector. The only difference between the cable I made that does not work and the Sun cable is that does work is that the Sun cable has all the lines cut up and fed through a toroidal ring and indead of a D-sub 25 connector it has an HD50 connector. The internal cabling is also about three inches shorter.
If I remove my cable from the bulkhead and try to rest it in a manner that it's far from the AC line and the power supply I don't have any change.
