Since when did disks become one time use devices? None that I have are.

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

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
