Oh, it was pretty quick. Once I got the hang of it, it was about a minute per drive. Unfortunately, you're supposed to reboot every time you flash one, but since I was just booting to the firmware update USB flash drive, that was very quick. If you had all of the 200 hard-drives just sitting there for you, you could do it in about half a day. If you wanted to be faster, I suppose you could have two machines going at once. Also, you're supposed to use an onboard SATA controller (just the basic type of one included in most motherboards today), since the FreeDOS version that Seagate uses doesn't have room for very many drivers.
