It seems the goflex can be formatted for the apple and be used without said app.
Why not do that?
As to the PC and MAC issue, deeply discussed so while NTFS will give ME THE BEST results I wonder if a public mac is up to date to use that.
FAT32 is an option but is not reliable for me.

Bought (and returned) a Seagate FreeAgent GoFlex Ultra-Portable External Hard Drive, 500GB, yesterday and tried to use it on a public Mac but couldn't because I didn't have the "admin" password to install the required compatibility software (and can't get one).
I need to buy an ext. storage device that can work with my WinXP PC and be written to on this public Mac running OS X. Please suggest a Brand and Model that will work for this, I am at a loss.
