Andrei,

Thank you very much for you kind reply and
both your messages.

Having said that, would it be possible to take
away on 72Gb drive (say Drive1 the second drive)
and shove in one of the two 146Gb ones ?

Shouldn't the array be rebuilt ?
Will it use the extra disk space though ?

Thanks,

spyros
