Since when did disks become one time use devices? None that I have are.
If its already full, you just tell the partitioner to use it all, problem
solved.

Sorry Brian, that is generally shorthand for "equivalent", aka the same
thing. IOW nothing precious on this disk, over write whats already
there.

Usually less than 4 megabytes of free space left at the end of the disk
with a used 4k per sector disk on the cable, but could be zero for a 512
byte per sector used disk since there is not normally an alignment
problem with the old 512 byte per sector formatting. I have 1Tb disks
that look alike at first glance. The 512 byte per sector pair is
heavier and a wee bit thicker because it likely has two platters in it,
while the 4k version pair is a bit lighter and thinner, I presume
because there is only one platter in those two disks.
The commodity drives I have coming will be, at 2Tb, 4096 bytes per
sector, and linux must align its writes with a Read-Modify-Write cycle
updating the whole 4k just to change one byte if things don't start on a
sector boundary. There's a pretty good speed penalty for doing that. A
disk that can write at 120+ megs a second when aligned can be turned
into a 20 megs a second slowpoke. if miss-aligned.
Ain't technology wonderful when it advances faster than ones legs can
walk? Before you know it, it will be Sir Arther C. Clarks definition of
magic. ;-)
Thanks Brian.
