Hi, I hope someone can help me out of this one... I plugged my brand new WD Passport Drive [http://www.wdc.com/en/products/Products.asp?DriveID=364] on my F8 box, and it appeared just fine (I had done this before -- I had even reformatted the partition with NTFS with Windows XP). I wanted to remove the single 250G NTFS partition and create two smaller ones, and reformat them as ext3 and HFS for my girlfriend's MacBook. GParted identified the device just fine, and I had just deleted the original partition and created two smaller ones (110G and 120G), unformatted. When I hit the "apply changes" button, GParted told me it could not see the device anymore. Indeed, it couldn't be seen anywhere. The disk was not mounted anymore, and did not appear as a device on GNOME's nautilus. Here's what's on /var/log/messages, showing what was going on right before it all went to hell: Jan 19 12:19:37 localhost kernel: usb 2-3: new high speed USB device using ehci_hcd and address 2 Jan 19 12:19:37 localhost kernel: usb 2-3: configuration #1 chosen from 1 choice Jan 19 12:19:37 localhost kernel: Initializing USB Mass Storage driver...

Please, please, please, someone tells me this can be fixed ={ Any advice will be welcome. TIA Andre
