Thanks, this allowed my windows7 pc to see touchpad as usb device again.For anybody out there that needs the fix for getting the drive to recognize in windows, the way to resolve is below. This is to get past the mkfs.msdos message you receive about it being a mounted file system. You first have to unmount the device, run the command, mount and reboot.
Ensure the TP is in Developer Mode. Connect the TP to the computer using the usb cable but don't enter USB Mode on the TP. On your computer, Open Novaterm and enter the four commands below (on mine, I was able to open novaterm by going to C:\Program Files\Palm, Inc\Terminal\ and double clicking Novaterm.bat. If opening that way, you'll have to click File->Connect in the Novaterm window. A window will launch asking you to confirm the TP device. Just click OK.. If you've done it correctly, you should be at a command prompt showing root@Touchpadname: / #):It will take between 5-10 minutes for the TP to reboot, so don't panic at the longer reboot. You'll notice that the HP logo will start the standard brightening/dimming on the screen. When it comes back up, you will be able to enter USB mode on your TP and browse the drive using windows.umount /dev/mapper/store-media
