Cloning a SCSI disk

[robin-fo]

Hi,

I'm looking for program to make a full clone (as a raw disk image) of a harddrive. Yes, I know Disk Copy, but it appears that it can only make a image of a single partition. I want to clone every partition, including driver partitions etc... I sadly don't have any Mac with a SCSI connector which can run Mac OS X, because 'dd' would be the ideal solution for me.

I know that the FWB Toolkit can make images of a disk, but apparently only in a proprietary (??) format. I need either RAW or Mac OS X compatible.

What do you guys use to make images for RaSCSI/BlueSCSI etc.?

In general there weren't raw or full-disk imaging tools for vintage Macs, and while DC6 exists it's got somewhat low limits that were never lifted making it tougher to use for hard disk scale stuff. (it falls apart after you put about 4 gigs of stuff on it, if I remember.)

Are you looking for blank images to put on one of those devices or are you looking to image a current setup onto one, or something else

I've seen talk about using emulators to prep images for Ra/Blu/Arduino SCSI, so that may be a starting point.

Another possibility is to prep a blank image, boot your machine, then just copy everything over from the old disk to the new one. (That's how I did things when I migrated my 840's stock disk to a scsi2sd v5 recently.) (Basically just treat it as if it were 1995 and you just popped a new drive in.)

Thanks! DiskCopy 6.5 looks very promising! I didn't know that this was possible with the latest version. My other alternative would have been dd on A/UX!

For RaSCSI I create a blank disk using the RaSCSI instructions, attach it to a mac with a patched drive setup, format it, and then work with it in Basilisk. Honestly though you can just take any raw disk image that works in basilisk and use it with the RaSCSI, it's pretty nice TBH. I just got one to play recently, and while I'm not swapping out my SCSI2SD's just yet, it's pretty freaking nice and very feature rich. Working with multiple images on SCSI2SD is much more involved (though a member wrote a script here to help, it's still not as easy as RaSCSI which literally has a web interface at this point).

I'll have to look at 6.5, does it claim significantly more capability in some sense

If I remember right either 6.4 or 6.5 was only ever really released as a beta and the headlining feature was .DMG cross-compatibility.

I typically use 6.3.3 out of "that's what was on S7T" habit.

Apple made one for internal use. It was released on my A/UX reference archive set, and runs under System 6 and System 7.

It can image one SCSI device to another, bit for bit.

I can’t remember the name of it, and I’ve taken my archive set offline. I’ll try and see if I can easily find it and point you in the right direction if you can’t find anything that works.

Was that DASH or DART? If I remember correctly that was meant for floppy diskettes, not hard disks.

No. It wasn’t Dart.

This was a utility made internally at Apple, which the name escapes me at the moment. It had an icon of an angry cat, and it was used for cloning one SCSI drive to another using the SCSI ID.

I tried it out and I cloned a hard drive, partition table, drivers, and all.

Here's an image of it on my archive:

Cute - sounds like it may not exactly be what OP wants since it sounds like what they want is to make a file to transfer to a modern computer to then use with an emulator or one of the newer SCSI replacers, but that would (in addition to "just drag the files over") work to populate a new scsi replacer with the contents of your existing system.

 

[Cory5412]

Actually, here's a better way to put it:

That tool will probably work, but using that tool instead of just "booting the system and using Finder to copy all the stuff over" will introduce unnecessary and uncommon tooling, making the process more complicated than it had to be.

Since we aren't exactly in the game of "manufacturing computers in bulk for sale at retail" this tool is interesting but not something I think most people should add to their tool bag at this time.

Anyway, thank you for sharing! If you can scare up a picture of it running that would certainly be neat!

will the dd command in MachTen or MacRelix do what you want?

How about silverKeeper?

It works if OS 9.0.4 or above.

Thank you guys for this overwhelming amount of support and ideas. My main goal is to preserve a 100% identical* copy (as raw or dmg disk image) of my ancient Mac hard drives on a modern computer (mainly for preservation, but also for emulators and modern SCSI SD solutions).

Meanwhile, I was successfully using either DiskCopy 6.5 (thanks again, @Cory5412 ) and the A/UX dd command to do the job. They are exactly what I'm looking for. I'm also happy to report that the dd image worked instantly in my BlueSCSI.

*identical: Not just in terms of file contents, but also considering (hidden) partitions like the disk drivers, A/UX partitions etc..

the A/UX dd command to do the job

Didn't realise you had A/UX installed. In that case this is the best answer for raw images indeed.

In fact, I currently didn't! But as soon as I had the idea, it wasn't difficult to flash macintoshgarden's "AUX_3_1_1GB_Use_In_Shoebill" onto the BlueSCSI without having to mess around with a SCSI CD drive and the A/UX installer.

 

[cheesestraws]

That was a good plan then!
