Dang it. My brand new SDHC drive stopped working. Upon the first insertion, it auto mounted corrected in FC7, so I started copying my MP3s over. It hung after little while and I couldn't recover. After an hour or so, I pulled the drive out of the USB port.

Upon reinsertion, I get nothing. /dev/sde seems to be related to it, but the kernel won't let me open /dev/sde to re-partition, wipe it clean and start over, nothing. :(

Please help! BTW, I tried a WinXP machine too. It couldn't see anything to reformat or repartition either. Certainly there has to be some way to force linux to access the device to repair the damage?
