Formatting an external HHD, utilities software

Recommended Posts

Hi guys,

following on from my scsi chain external HHD issue (the system attempted to load from the external drive over ruling my internal HHD be it unsuccessfully). Trash recommended SCSI probe utility software thinking it maybe simply a SCSI channel conflict, as it turns out the utility software picks up the external AVID HHD just fine under any channel i set it yet still nothing. I thought maybe first Aid may repair the drive but it didn’t show up within that software only the internal HHD and floppy.

1.) i don’t know if the drive is formatted for mac or if it works for that matter any ideas on how to test it? 
2.) way to format it?

note; It’s a rather old and massively heavy full height HHD which also made a funky sound whilst spoiling up but settled quickly .

 

any ideas of a way forward would be much appreciated.

Try Patched Apple HD SC Setup. Sometimes it can force the drive to mount if it is at all able to. If not, there are other options within, such as repairing the actual drivers.

If you want to format the drive you can use Lido. Most of my HDDs were formated with Lido sucsessfully.

Is the last SCSI-device terminated?

Internal drive should have SCSI ID=0. The external should have a higher value (like 1). As  I remember right, only the Mac Plus booted from the device with the highest ID.

Hi guys,

thank you both i’ll try those tonight. Yes its terminated with a 50pin terminator plug.

 

does it matter if you plug the scsi into the top or bottom connector on the back of the HHD (both are unlabelled) and I’ve plugged computer into the top scsi port and terminated at the bottom?

 

thanks

Bit of background and picture.

I’m not sure of the age of the drive (brought it off eBay). When i cleaned out the dust i i was surprised it was a full size HHD i believe 5.25 inch 2.4gb but has limited information on it anywhere. It weighs a ton though and takes several seconds to spoil up (sounds some what like a jet engine).

 

about 3-4 seconds into the 7-8 seconds it takes to get up to speed i get that scrubbing (funky noise) only briefly for 1/2 a second almost like its out of balance or warn barrings until its fully up to speed so it may indeed require repair but it managed 15 minutes powered on seemingly ok.

Hi Dochilli,

it definitely tries to boot from the external first even with the scsi set higher than the internal id which is set at 0.  I’m more used to ide drives so opened them up thinking a misplaced jumper pin was the cause yet scsi doesn’t have those as i found out after taking my se/30 drive out and the avid HHD apart to check. I’ll definitely try lido when i get home from work :) it may just need the correct format for it to work as expected. Mind you isnt this part of the fun of using the old gear as we’re so used to plug and play usb these days this old kit makes you work for it lol

The machine starts searching for drives at address 0 and works up, so it will boot from the internal no matter what unless the drive is not system folder-equipped or you have set it to boot from the external via software.

 

As for the drive, I assumed you were trying to rescue data. If you are not, just try and obliterate the thing with lido or the patched setup application. If there is a hardware issue it won’t work, and the. You can just toss the drive.

Hi LaPorto,

No not really i doubt there’s any data on it i  just wanted some extra storage in a vintage style (its an exact fit under the compact Mac) and as i have used a fair amount of the 1gb Internal drive within my SE/30, having the extra 2.4gb for software and games is what i was after. I saw this on ebay advertised as a vintage macintosh SCSI HHD so I wrongly presumed it would just work. Likely hood is it either doesn’t work or lacks a file system so yes i’ll attempt just to obliterate it as i have little to loose, it was only about $40 6-7 months ago when i came across it. Thanks for your help its much appreciated :)

When you say "via software," you're probably referring to the Mac SE and newer machines which use the Startup CDEV to set the boot device, and retain this setting in PRAM.

I say i’d like the classic hardware but reality is SCSI2SD is probably much more stable.

Didnt work unfortunately i get an arbitratry failure which then crashes the os is sats check connection and terminators. I think its worth pulling everything out and trying i different cable and using my zip drive as the terminator. Weekend job as it means ripping all the wires out. To be honest i think the drive is toast but I’ll give it one final go. :)

If the drive is dead, I would open it and look if the reading arm is stuck. Sometimes a little push with your finger moves the arm. I could get some drives back to life by opening the drive. Old drives have sometimes some rubber bumpers that have become soft and sticky with the years.
