Stopping a machine while imaging

[tatiang]

What is the best/safest way to stop a machine from imaging during the
imaging process? In the past, I manually shut down a computer and the hard
drive seemed to fail. I'd like to think it was coincidence, but it may not
have been since the hard drive was obviously spinning when I powered off.

I am definitely 100% guilty of cutting power half way through imaging - on purpose. I don't think it is "best practice" but I have not seen it hose a hard drive physically. Every time I have done it I can just reimage it. Now I have seen a failing HD have so low performance with disk I/O that it literally crawls when being imaged and I kill the power on it and it happens again. That is not really the imaging process that is the issue though, that is a failing HD with really poor disk I/O.

Hi,

Well ive powered off a mac many many times during imaging and when its crashed etc, the disk will be spinning and it is by no means good for th drive but shouldn't destroy it the first time. A computer should never be powered off by just killing the power, but hey we all do it, but a sudden cut of power is not good and over time can destroy a drive if done enough times. But theres plenty of other ways to destroy a drive. A HD has about a 3yr life span so should be considered a consumable part like a battery.

I've only started using Casper Imaging, but I've been able to simply force-quit Imaging and then shut it down since the machine is netbooted.

Yes, force-quitting works for me as well. It does leave the server volume

I have to do this.
