Ok, here's the situation:
A two drive 5.25" external case with 80w Power supply (you've all seen them before). It has internal 68 pin cabling, two positions.
Two Drive trays for 68 pin drives (the kind with a keylock on the tray that also turns the drive on and off, and has a power and hdd busy led)
External 68 pin Cable
LVD external terminator
I picked up all of this from a guy on Anandtech, for only 45$ shipped. He said that he couldn't get it to work, and just wanted to get a rounded SCSI cable and terminator out of the deal and would take 45$ for the whole thing. That being said, I figured there was just some mis configuration on his part that was preventing his drives from working (he said he was new to SCSI).
Now I have the enclosure in my hands, and I think I have narrowed a problem (possibly what he was having) and would like to hear other opinions/where to get replacement parts.
Here is what I was using previous:
1 Seagate X15-36LP 68 pin
1 Maxtor Atlas 10K III 68 pin
1 LSI U160 single channel 64-bit card in a 64-bit / 33 mhz slot
1 Internal SCSI cable with terminator
Both drives installed on the same cable, no SCSI IDs hardwired with jumpers. Terminator at the end of the cable.
I know all of these components to be working, since they are in my machine.
Here's what happened when I tried to install the two drives into the external box:
The drives are not hard set (with jumpers) to SCSI IDs, the box is terminated on the outside with an external terminator.
1)When plugging in the two drive trays, the setup will only work when the bottom drive is plugged in. If both drives are plugged in (their trays inserted, not necessarly on or off) the SCSI card will freeze during detection.
2)If the top bay is unplugged, or the tray removed, both drives will detect and work fine in the bottom bay. The hot swap tray can simply be plugged into the bottom, and both work as long as one is not plugged into the top. This leads me to believe that the trays themself are fine.
3)If the drive bays are removed, and the drives plugged directly into the cables, the same behavior is exibited. The bottom postion on the cable will work fine, as long as nothing is plugged into the top position. Plugging a drive into the top position only does not work either. This leads me to believe that it is not the drive bays that are causing the problem. This also tells me that the SCSI ID assigning shouldn't be a problem either, because this is basically the same as me plugging the drives in as I normally have them.
From this, I concluded that the cabling inside the box is possibly bad. Perhaps the crimping for the top position inside the box has come apart?
Does this seem like the right conclusion based on these facts? If so, where should I get a replacement internal cable (since it needs the male connector on the outside of the box)?
If not please suggest your solution or ask me to try something to test so we can have more info.
