Time machine initialisation very slow

by fosterpapillon / December 29, 2012 3:29 PM PST

I've just bought a new iMac and I've moved my two external HDs from the old Mac to the new. I've designated a 1TB HD as my Time Machine disk and started a new back-up of 92 GB (excluding all external HDs, System files, etc). The HD is mains-powered and has a USB2 connection.

The back-up ran - it took 8 hours and then stalled for over two hours at the "Cleaning Up" stage, so I just restarted the Mac and erased the HD.

I've repeated the process and the message of time to go varies from 6 to 7 hours.

This never happened on the old Mac - a new back-up took only an hour or two.

Is something wrong?

Not necessarily,

the first backup usually takes forever and is best left to its own devices.

Just leave it running and you will probably find that it will, eventually, get itself sorted out.

I think it's died

I erased the HD and tried again - this time the estimated time was 19 hours. I quit and erased it yet again and now Disk Utility tells me that it's a 137 GB drive - somewhere, I've lost 860 GB!

A quick check yesterday showed that transfer of a 5 GB folder took about 5 times as long to the Time Machine HD as to the other external drive, so I think it's dead.

Thanks for the comments.

It's a possibility, but

try the initialization again, just for fits, grins and giggles.

No - I may try it on a PC and see if a Format there does any good but I'm not hopeful.

I partitioned my 2TB drive to make a new Time Machine - 200 GB backed up in 4 hours.
