Hello all:
I have a Seagate SCSI hard drive running in a Turbo slab that has scads of hours on it, (running 24/7 since 1993) and now making funny bearing noises.
I'd like to see if I can clone this drive to a newer, healthier SCSI drive. (1 or 2 Gb), but keep intact my docs and apps.
I've read the posts here on different techniques to do this, and they all sound way too complicated.
Is there a newer Linux tool or utility that could be used to make a bit for bit copy, and allow the new target drive to just boot up and work?
thanks in advance.

If the new drive is under 2gb, just use the disk utility to clone your existing drive.

Thanks. Are you talking about the NeXT BuildDisk app?
gregor
Yes, that's the one.
you can also use dd, very simple to use
BuilDisk.app only will give you a freshly installed operating system, NOT a clone. for cloning I use dd on OS X or Debian.
Thanks- I didn't think Build Disk would clone a disk, but wasn't sure and thought I'd defer to some experts.
I do have a Mac mini running OSX, but haven't figured out how to a attach 2 scsi drives to the thing yet to run the dd process.
Will keep trying.
thanks,
gregor

to my best knowledge, there's no reliable solution to connect SCSI drives to a Mac mini. I use OS X to copy images to/from the various CF-Cards I run in my cubes. if I need to connect SCSI drives I use debian running on an old COMPAQ Deskpro which is equipped with an ADAPTEC hostadapter.
Yep, thought so. I'll connect a SCSI drive in an external scsi case and use the unix dd command to try to get it done.
Thanks

Anyone have a step by step procedure on doing this? I have an internal SCSI drive that takes about 30 minutes of warming up before she boots my cube and have external SCSI drive I could connect to it.
would be nice to make a exact duplicate of this drive to boot from.

I know that to use the dd command, you have to establish the scsi id of both discs. I get this during the verbose mode boot up screen, where it gives the drive name and capacity, I.E. Seagate 31200N, Rev 86480, 2 G, sd0, and the second connected disc, Micropolis 2217, 1Gb, sd1.
Then once you have established the scsi id, enter the dd command:
dd if=/dev/rsd0a of=dev/rsd1a
where if= is the input source and
of= is the id the target (destination disk
I've read cautions that you CAN NOT screw this up, or will toast your source disc.
It is supposed to create a byte for byte copy of the source disc, including the boot sectors and any existing partitions
Will let you know how it ends....

There is a procedure posted that successfully clones a drive. Please read the thread below and read next chef's post. I have used it a few times and it has worked perfectly for me.

Glad to see others are still getting use out of that writeup. :D
