If after creating partitions with the OS Setup or DOS, you still have problems, there is something wrong with the drive itself. Get a replacement if its under warranty or just buy a new one. They're relatively cheap nowadays.

ps. Why haven't you asked Samsung about this? They should help, even if the drive is out of warranty.
