Backing up 80MB HDD to ZIP

[NoTrueSpaceman]

Due to limited access to options, I've got an external SCSI ZIP100 connected to a Mac IIsi with the original 80MB HDD. It has a bunch of historical files from the original owner I'd like to preserve.

What software should I be using to back the drive up? I assume "just drag all the files over to copy them" isn't sufficient. I'm using the System 7.5.5 ZIP100 disk image available here, so that's what tools I have access to.

Thanks!

If you could fit a System with the Zip driver on a floppy, I would boot from the floppy and do exactly like you say. Just drag the everything over to the Zip drive.  Using another System ensures that nothing would be running (such as system extensions) that may have some copy protection on them. It could cut down the amount of problems you would have copying it all.

If that isn't feasible, I would drag and drop the items one folder at a time to the Zip drive, so if there is a problem file that doesn't want to be copied, you only have to look in one folder to find it.

Hope this helps,

Actually that is all you need to do.  Then you can make an image of the disk and read the files of the image in basilisk

Thanks folks! I got my backup made. Here's the full run down to help the next person who comes along.

My floppy literally shot smoke out the front a few weeks ago, so I don't have a floppy drive any more.

I ended up booting on a ZIP disk and copying it's system folder over alongside the one on the HDD. Then I blessed it using System Picker and rebooted onto the HDD. Then I  removed the IOmega drivers that had been in that system and rebooted.

Then I installed the latest IOmega drivers. And rebooted. Those kinda didn't work so I removed those as well (and rebooted), and I was able to use the ZIP Guest application to get access back to the ZIP drive.

I used the ZIP Tools to get information on the ZIP media I had to make sure it was good, then dragged the whole HDD icon onto the ZIP disk icon to make sure all the desktop aliases and everything were backed up.

And if you're wondering "why so much driver churn?" - I wanted to make sure I knew exactly what version had been used to make the backup in case that ever became an issue. The HDD was the one the machine came with and is essentially in an "unknown" state. It turns out the original system might have been 7.5.

I'll be booting my 486 Compaq with a parallel port ZIP drive into Linux so that I can make a raw image of the disk for future exploration in Basilisk.

There is a utility for the RaSCSI that I THINK allows it to directly clone a SCSI drive to an image. That might be an option for the future, if you don’t mind a little experimentation.

Disclaimer: you need a FULLSPEC board, which I think you have. Also, I’ve never tried this myself. Just seen the code out there.
