format series 1 drive before moving to series 2?

[Esteban]

I replaced the factory 80g drive in my series 2 D* with a 120g drive that was in a series 1 Dtivo I no longer use, using the WeakKnees interactive guide. All went well and capacity increased from 70 to 100 as reported in messages and setup. But I got to thinking, shouldn't it report 105 hours, i.e. 40g = 35, 80g = 70, 120 g = 105?

Should I have formatted (or clear and erase or whatever the Linnux term is) the replacement drive first, or does this automatically happen when restoring to it with mfs tools?

You didn't do anything wrong. Mfsrestore wipes disk clean and reformats on the fly. Hours can vary from different manufacturer to manufacturer on the same capacity drives so you get what you get.

Good to know. Thanks.
