No access to Memory Stick Duo

Hey guys
need a little help with my psp- memory stick;
i formatted it for my psp, plugged it in my card reader to copy files from my os and now i can't read/write or even see the memory stick duo on my desktop after i plugged it in.
just in the disk utility there's a entry but no possibilites to erase/restore or stuff (Mac OsX)

in windows when i tried formatting the stick it just says that it's protected
???


tryin' to reformat it with my psp hasn't worked either
then "Formatting Failure"

any help for me?

maybe you erase this file by accident, MEMSTIK.IND and that is why your memory card isn't working, i send you this file by e mail, so whats your e mail

thxalot
yeah i thought so, but the problem is, that i can't get access to the file so i can't copy stuff on the stick
so how should i get dhe memstick file on the sick?

If you have nothing to lose in the ms, or have your back up of your saved games, just have PSP format your stick.

so u own a mac!?

in any case, MAC will recognize your MS through PSP USB as a mounted drive.

also OS X will not let you write anything to NON-MAC formatted drives!!!!!

Just try to have it recognize as secondary volume.
and keep it in your psp.,

so u know when i try to mount my ms it just say, it doesn't mount it really
i can see it in the disk utility but trying to repair it failed
formatting through mac/ps/psp hasn't worked....
no way to get through
