Quadra 650 nubus

Forgot to mention that it is a 50 pin hard drive. Not sure why it has four jumpers but there is no adapters and it is definatly 50 pin.

EDIT - alright jumpers put on SCSI term and term power, and now it is recognized by HD SC setup, formatting as I type this, thanks!

1. What is the model number of the drive, this is normally printed on a label somewhere?

2. What does "SCSI probe" say about the device?

3. Have you tried adding an additional SCSI terminator?

 
Alright guys, more problems.

During the format, the mac accidentally got unplugged and on restart hd setup doesn't recognize it again. SCSI Probe show a bullet beside the 0 , the legend at the bottom says this means "no data". Any way I can get this thing formatted and maybe it will mount?

If this was during the low-level format then you are likely to have turned your drive into just a curious lump of metal and plastic.

There are two times when loss of power can be fatal to hardware...

i. low level format of SCSI drive

ii. flashing of system eeprom

I think you may have hit case i.

 
Yeah thats what I was worried, i guess i'm screwed then > :(

I guess its back to ebay if this thing is "a curious lump of metal and plastic"

The stupidest thing happened too - I opened a drawer to get a radio out, a loose cord caught on the power cord and pulled it out of the wall.

 
I'd go for one pulled from a Mac, as they're much easier to format. Otherwise, you will need something beyond your stock install disks to initialize the drive - something like Silverlining, or a patch (which is widely available) for the HD formatting software that came stock with Apple machines of your era.

A WD 7200 RPM drive is most likely going to be wasted on the scsi bus of a Q650 anyway.

Same seller:

I have one of these in my Q650 and it works exceedingly well: quiet, roomy, and perfectly snappy for its intended purposes. (It's partitioned into a couple of 2.x GB drives under MacOS7.6.1, which is necessary with a drive of this size under anything less than OS8.1, and makes for the most efficient use of space under any OS a 68k machine can run - since a Quadra can't boot from an HFS+ formatted drive).

 
Yeah, thanks i think i will go after one of those. The only reason i got the other one was that it was cheap. My HD SC Setup is patched btw and it was working until it got unplugged. I guess it is going in the trash.

 
Try low-level formatting it again; SCSI drives as a whole don't die if you botch a low-level format, you just have to low-level format them _again_. That's because the drive firmware is stored on a chip instead of on the disk.

You might need to use something like SilverLining or the MicroNet Utility.

Yeah, but it doesn't show up in Hd setup anymore, have to try another program i guess.

Not much opportunity to try another low-level format, really.

SCSI Probe is pretty good, it does nothing with a disk's data, it just talks to the SCSI controller on the disk, which in this case I think, has got very confused.

 
'Low-level' formatting, which defines the data tracks and their spacing, is done at the factory with precision gear. Probably no formatting utility that gets into the hands of users can do this, and certainly the gear isn't available to them.

Formatting a drive by a user is a matter of erasure of existing data (if erasure is invoked) and writing the logical structures (partitions) and drivers to the disk. In Apple's case this is at least five partitions, only one of which becomes the 'volume' mounted on the desktop.

If you cannot 'see' the data volume on the desktop you can choose between dead drive, scrambled or missing driver, defective cabling or power supply to the drive. You know which you can eliminate in this case because you are there. If it is the driver, because early Apple disk utilities are less capable of 'taking over' drives that have been formatted with a third-party utility, although they should be able to unmount and repair Apple-formatted drives, you need Silverlining (LaCie), FWB's Hard Disk ToolKit, Intech's HD SpeedTools, ATTO's utility or the like. All of these can follow Apple's partition scheme and provide the requisite drivers (plural).
