I recently upgraded from an old G5 iMac to one of the new iMacs.

I retrieved the HD from the old machine and have now mounted it in a new
enclosure. The connection is USB 2.

Today I upgraded my copy of Diskwarrior 4 to v 4.2 (and following
Alsoft's instructions burned a dew DW disk) which should work with
10.6.2. I tried it,but the OS on my old DW disk was 10.4.5 and after
about 30 minutes of a white screen and no noise from the disk drive I
shut down and started to think about what I could do to improve things.

My idea is to erase that older HD and install 10.6.2 on it so it could
be a start up disk and then load DW and other maintainence utilities.
That should make things a lot speedier.

Will this idea work or am I heading for trouble.

TIA

I don't think so... I have also the latest ver. of DW running on my
Leopard 10.5.8 as well as on the original 10.4.11 on my MacPro. If I
boot from the Tiger volume, I can check and repair the Leopard volume
and visa-versa if needed. I also have the DW on my external bootable
backup disk, and it also works just fine from there. The only difference
between your setoup and mine is that I only use external Firewire disks
instead of USB... But do note that booting and running the system from
an USB disk will definately be slower than running from a Firewire disk.

Cheers, Erik Richard

I have a real dislike for USB for sustained or hi-volume connections. FW
is way better, though I have no data to back that up.

Indeed FW is better - both FW400 and FW800! - FW400 is apprx. 40% faster
in 'real life' if you copy a folder containing many smaller files - fx.
images from an internal disk to an external image backup disk. And FW400
is apprx. 10-15% faster if you copy a single big file such as a .dmg or
.sit file. And FW800 is by near as fast as if copying the same
file/folder between two internal SATA II/300 harddisks.

I use only external FW disks and right now I have 6x FW400 + 2xFW800
disks and I copy and move lots of files all the time from and to
different disks.

A little example. - I have a highspeed USB pendrive using highspeed SD
cards, where I store a folder with all my homemade icons - apprx. 19.000
different icons in two types - a JPEG2 format icon and a PSD format
icon, so all in all this is apprx. 38.000 files in a single folder of a
size of apprx. 2,6gb. When I copy it to the USB pendrive it takes apprx.
1 hour and 40 mins. When I copy it to my external FW400 'archive' disk
the same folder only takes 14 mins. to copy. The same folder is also
saved into a Toast image and when I copy that image to the UsB pen, it
takes apprx. 6 mins, and to the FW400 archive disk just about 2:45 min..

Cheers, Erik Richard

Thanks for the info,but to get back to my original question, can I make
and use a disk utilities disk the way I proposed in my OP?

TIA
