No official answers have come from Seagate yet as to how the drives can be fixed, if at all, without sending them in for warranty replacement. They have, however, pulled the SD1A firmware from their site while they investigate the cause of the problem. With the number of people suffering from bricked drives, you'd imagine that Seagate's QA would have caught such a glaring error. I personally have flashed several 7200.11 drives using the SD1A firmware with success, but those were all 1TB and larger drives.
Seagate has already stated that they will offer data recovery services for damaged drives. Is that enough, however? Will Seagate's reputation suffer from this incident?
