yes , i am sure the drive is ment for at least warm swap, i dont really need 
hot swap, i decided do to my accendital formating of important partitons i 
am
going to have a "warp swap" setup with my ftp box, ill swap the drive to my
new box to update it or when i need a iso to burn, otherwise my data archive 
will
remain on my ftp box, not on my dev box :) i just want warm swap so i dont 
have
to transfer 600 meg files, even on lan this takes..6-8 min, and i dont want 
any
important data, even a copy, on my dev box unless its being used in a 
current
project.anyway.....im sure the bay is ment for warm-hotswap, it was really 
cheap,
so if anyone knows of a quality ,reliable, tested warm-swap ide setup could
you please let me know.

also...i always umount before swap

thanks,
jd
