I have 2 dead Transcend 8GB SDHC cards and have tried formatting them using a USB reader and a myriad of software tools in Windows, Mac, Linux, and also Maemo. Neither of them have been recoverable.

On one of the cards, I was enjoying using KDE when all of sudden it locked up and after a couple seconds my N800 rebooted. Once it got to the Boot Menu it did not show my cloned partition as being bootable and the card was not even seen by Maemo.

Just wanted to warn you that after spending hours trying to recover your card, it might not be worth the time trying. Transcend cards have a warranty, but I haven't gotten around to requesting replacements.
