Now, one last question: what's the flag to format a FAT32 partition with
mkfs? I saw options for pretty much everything but that. I'm probably
just suffering from not having had my first cup of coffee... :)
I deal with this often, as its part of my job to produce bootable pen
drives and CF cards. I like using pungi and revisor to roll a product
specific distro, and using livecd tools for copying them to the pen drives.
Most of this is scripted for convenience, but all new drives go through
a process like this:
Stomp on the MBR:
cat /usr/lib/syslinux/mbr.bin >/dev/${disc}
That particular file is a generic GPL MBR. Its part of the syslinux rpm.
Run fdisk to delete all partitions and recreate just what is necessary
-- the script for that is kinda hard to read unless you are intimate
with fdisk, so I won't post it here to prevent confusion.
Be sure to tag the primary (assuming 1 here) partition as bootable.
Then to format:
mkfs -t vfat -F 32 -n "$name" /dev/${disc}1
Some vendors like to really mess with their thumb drives, requiring a
bad sector check during format. Add a -c to the above for that. It
takes a bit longer, but might help on a stubborn drive.
Good luck!
