RAW suggests there is no partition on the drive. Also, the fact that it has been marked Active may be the reason you can't format it.
If you can get by without recovering whatever data is on it I'd remove the Active flag and partitions, then repartition it and use the Quick Format option.
Or you could, as dsperber suggests, use Partition Wizard's partition recovery wizard.
Do remove the Active flag, though, as I'm convinced that's part of the problem.
Partition Wizard, as mentioned, is an excellent partitioning utility. Partition Wizard : Use the Bootable CD
