Extremely slow passport elite, can't reformat- says it'll take 21hrs to remove just 5gb

My 500gb passprt elite started running incredibly slowly shortly after my itunes failed and I was told upon reinstallation that my library (stored on my passprt) was corrupt. Trying to add music to my library took ridiculously long- I only managed a few gigs in 12 hours. The disk fragmenter and windows checks will not work and I can’t reformat unless I remove all my files first- something which will takes weeks after being told it would take 21 hours to transfer 5 gigs to my computer. Oddly though, I can cut and paste files of several gigabytes from my computer to my passport with no problem at all. Occasionally windows explorer freezes when I open random folders.

Hey, I just bought a new Passport Elite and it does the same thing. It’s extrememly slow when using the SmartWare, but copies fast when I drag and drop.

Anybody know what to do?

Just drag and drop?
