I'm looking for a shortcut here...

Installing A/UX has been a real pain for me... I haven't been able to get it to work at all from an external CD-ROM... I've had to use a CD-ROM connected to the internal bus... its ugly, but it worked. I've done it 2 or 3 times. So now I have at least 2 booting A/UX machines.

Can I take a good working A/UX system on a scsi drive, stick it in, say, a G3 w/ scsi card & Tiger, and create a disk image of the A/UX disk so that I can image subsequent drives for another machine?

[Could it be done from OS 7, 8 or 9? or from NetBSD? Linux?]

What are the issues here (Filesystem/disk drivers/??)?

If this sounds plausable... what software would I use to create (and subesquently burn) the disk image (Toast TItanium?/Disk Utility?/??)?

You could probably copy the entire drive bit-by-bit using UNIX dd or using Disc Copy and making the image "from device" and just copying the drive or partitions. Writing it backto something to be useful would be the main issue.

image?

Would I be left with a mountable image?

I'm not even sure what filesystems are on a A/UX disc... must have a small Mac OS Standard partition for 7.1, I think...

NAME
dd -- convert and copy a file

SYNOPSIS
dd [operands ...]

DESCRIPTION
The dd utility copies the standard input to the standard output. Input
data is read and written in 512-byte blocks. If input reads are short,
input from multiple reads are aggregated to form the output block. When
finished, dd displays the number of complete and partial input and output
blocks and truncated input records to the standard error output.
----

so maybe if I stuck another scsi disk in... I could just image it directly?

If it is the same make and mo

If it is the same make and model of drive then you can probably just copy it right over through dd. If you just want to save an image of the drive you can direct dd to put the blocks into a file with some thing like:

dd if=/dev/sda of=/Users/me/Backups/AUX-image.img

Of course my example could point to any drive ( /dev/sdX ) or any file, and my use of .img was random. Smile

re-imaging?

same make and model drive is a prob... I have all different kinds...

but anyway...

then... to reconstitute the image back to another drive...?

What are my chances here that this is likely to work?
(appretiate your help... )

Block copying like this gener

Block copying like this generally copies the whole partition map and everything for the drive. So, if you copy a 500MB drive and try to put the block image on a 1GB you'd only see 500MB of the copy, as the partition map would only show the 500MB setup of the original drive. There are also other problems such as bad-blocks, etc. I've not done a copy like this from anything and tried to put it back. I have taken block copies and mounted them later to get data. So, if you do want the backups just for the data, it's pretty easy. To copy the drive gets into a bit of gray area that I've not done directly.
