Old External Hard Drive

[Bobdude161]

I've had this external hard drive for a long time.

A few years ago I decided to take it apart and tried to install a newer one in it, but then things got complicated and forgot about it.

Today, I found it hiding in a closet and took a look at it. It's like a normal external hard drive except it came with a few extra wires.

Looking at the hard drive that came with it, I can see some extra pins that I've never seen before.

Taking a wild guess, the red and white wire 2-pin connector goes to the one pictures two up. Now there are 2 3-pin connectors left that seem to be wired to a SCSI ID number thingy (I know there's more of an intellectual word for it but this is all I can think of)

Labeled next to the pins on the hard drive pictured in the last picture are:

SS EP WS
[ - - - ]
[ - - - ]

A2 A1 A0
[ * - - ]
[ * - - ]

*
* means there is a jumper there

I'm not sure what this is supposed to configure.

Is there any way I can bypass this so I can install a newer one?

Looks like you've got an old Quantum ProDrive of some sort.

The black/red wires are probably going to a drive activity led. The other small ribbon cable is, well, I don't know. I like to think if I don't know, they are unnecessary. As for the other items they are as follows:

SS: self-seek testing of the drive mechanism
EP: parity checking of data on the scsi bus
WS: wait/spin option on power up of drive
All 3 should have no jumper.

The A0, A1 and A2 jumpers are for scsi ID setting of the drive.

A0 = 1
A1 = 2
A2 = 4

Combining these you can set your scsi id from 0 - 7. Yours is set for 4.

Man, this is some old knowledge being dredged up.
