TI/Linux gurus,
I've created two SD Boot cards with two different types of SDs (Generic 4GB & HP 8GB) for the first time with minor glitches. Rebuilding the same SDs for the 2nd time has been a nightmare.
Command:
$ sudo ${EZSDK}/bin/mksdboot.sh --device /dev/sdX --sdk ${EZSDK}
Where
sdX = sdc

If you created or changed a DOS partition, /dev/foo7, say, then use dd(1)
to zero the first 512 bytes: dd if=/dev/zero of=/dev/foo7 bs=512 count=1
(See fdisk(8).)
Formating /dev/sdc1 ...
/dev/sdc1: No such file or directory

The above error is similar to this issue as reported by another Linux user:
http://askubuntu.com/questions/124565/mkfs-vfat-unable-to-open-dev-sdg1-device-or-resource-busy
I had to use many disk tools (GPARTED, HDDLLF similar to fdisk) to reformat the SD card to FAT32 many tried before I could successfully rebuild the same SD Boot card.
Is there a simpler procedure?

ps. I've used different SD & MMC readers
