4GB Micro SD I/O error...

Hello,

I recently flashed a new rom to my HTC Desire, and all was working well.

But, i had to partition my memory card into 3.

Partition 1 had to be FAT32
Partition 2 had to be ext3
and partition 3 had to be a linux swap-file

During the re-partioning the phone crashed and since then i have been unable to recover it.

I have tried the usual format it again, but windows refuses to accept that the micro sd is inserted.

More annoyingly i can put the micro sd card in my phone and format it from there, windows will then pick it up again but only if i plug my phone in and switch to mass storage, but as soon as i try to copy anything to or from the micro sd card, i get an error message saying I/O Error...

I have downloaded software to format the card, and it does, but then the same thing happens as above...

Is this it for my micro sd card??

Thanks.
Pegasis.
