I didn't give it an estimate no - If i were to would i estimate the
'uncompressed' capacity, in this case 100gig?

I'm loathed to stop it now as its been running since yesterday afternoon and
is currently

Estimated time to write 2 * 1024 Mbyte: 174 sec = 0 h 2 min
wrote 3167649 32Kb blocks in 9687 files in 27409 seconds (short write)
wrote 2930929 32Kb blocks in 17898 files......

so i think it might be nearly finished?
