Some IDE USB adapter chipsets get the endian wrong for model name This fix identifies a endian swapped model name and corrects it. The function currently only includes Samsung but I'll add more IDE drive manufacturers as I come across them. This is peculiar to some USB IDE adapters. I've never seen this issue with SATA, ATA drives connected directly to the motherboard.
