Memory stick problem

[Seeth7]

Hi. I have a phat psp running firmware 3.90m33 and a 2gb sandisk msd. The problem is, it's not reading the msd, no matter what I do.
I insert the msd on the psp and it says it cannot be read and that I should format it, but I can't do it with the psp. I've also tried to format de msd with another psp and with a pc, but I had no luck.
I also tried to recover it with the pandora, but since it doesn't read msd's, it didn't work.
Help, please.

Looking into it, thanks.

EDIT: This tool seems to be for msd's, but i belive the problem is form the psp, since i've tried other msd's on it.
