Re: How long to initialize disk?

Rob:

You and I apparently got very different interpretations out of Phil's post. I 
think what he was saying was that his total time was approx 200 minutes for the 
series he went through and that your time *might* work out similar.

I think he was implying that if 1 drive takes 50 minutes, then 10 drives would 
also take 50 minutes. This would be because the actions take place in parallel. 
{I.e., "the number of disks (1,2 or 3) did not seem to make much difference".)

I wish I'd taken good notes during times I've installed or migrated drives; 
it's not an everyday thing for me. But I recall that a number of actions did 
happen concurrently. Formatting seems like an obvious parallel activity.

But... YMMV and ICBW.
