Dead Quadra 660av, and how best to attach second internal drive

Hey,

Diddle the CUDA button on the mobo. It's a red button on the mother board. Unplug the 660 first, hold the button for 10 seconds or so.

What hard drive did you add?

I think the scsi I put in was not identified properly and may not have been properly designated the slave.
But, I have a new quadra on the way to do some part swaps and I'll let you know what happens
Also, quadra 660av does NOT have a cuda button.
More later.

No such thing as slave in SCSI. Did you not get the SCSI ID set right?

Hey,

You said:

"Also, quadra 660av does NOT have a cuda button."

Sorry about that, chief. Never can remember which quads have them and which don't.

Yep, no master/slave relationships in SCSI land, but all devices on a single chain have to be jumpered to different SCSI ID numbers (and not 0 or 7, I forget which, which is the ID for the motherboard). Instructions for setting the jumpers should be printed on the disk labels. This includes an internal CD if there is one.

Where physically are you putting a second internal HD? Without case modding, there's only room for one, if you have an internal CD.

There is a neat, perfect space under the single drive that is there now.

Second question, I have a 500 meg internal hard drive, made by IBM for Apple, that I've kept for years after removing it from one of my old powerbooks. I can't get it to mount using the usb-scsi adapter. Any suggestions? It does whirr up and clickety cliks but then settles down and is not seen by my powerbook.

Clickety clicks? Sounds like a dead hard drive. External hard drives on the SCSI PowerBooks can be flakey sometimes. Is the drive terminated? If so try removing the termination, if not terminate it.

But clickety click doesn't sound right.

Re the 660av,

- you should check your SCSI id's as it's likely they are both set to ID 0 if that second drive came out of another Mac.
- also check and see if the hard drives have internal termination. You will see a black or tan pair or terminating strips when you look at the hard drive upside down back where the SCSI ribbon cable attaches. The main drive SCSI 0 may have it or if you have the CD installed it may. If the drive you are adding is also terminated this could cause problems.
- if you are using a different SCSI cable than the one that came with the Mac (it can handle two devices) check and see if the cable is good. Sometimes when these cables are stuffed into tight places they can get punched by a sharp part and that can break the cable causing problems.

And many PowerBooks didn't supply termination power, so the drive may need to be set to do so.

Thanks for the suggestions. I will try to figure out the termination and power issues ffor the scsi second drive but right now I'm far behindin my other work so I have to avoid the 660av time sink. However, I've been gathering data and hope to use the disks in the 660av to do some intense data cranking and shifting.

The old IBM - INTERNAL drive for the powerbook worked well when I decided to change it for alarger disk. The clicking may be insufficient power, like the old fords and chevys when the batteries were too low to do anything other than make the solenoid engage, and click.

Again, thank you and I'll be back after I get caught up on other stuff.
