De-Raiding a Drive

I recently swapped out an old Seagate 160GB SATA drive from my RAID-0 array and installed it into an external SATA-USB2 enclosure. Now I can not format the drive in any application I can find (Partition Magic, Ghost, Seagate Tools), even a Low Level format just comes up with access errors. It seems the original RAID setup still on the drive is preventing formating access. I can create partitions but they simply show up as RAW or unformated partitions in Partiton Magic or the built-in Disk Management. I also can not plug it back into the RAID as nuking it there will also nuke the other good drive which needs to be connected to give access to the RAID BIOS utility. I've only got 2 SATA ports so I can only connect it via the USB cable or in a pre boot state without the RAID connected.

Any ideas how I can nuke this drive?
 
You can't separate RAID 0 drives without nuking both of them. You have to put them back together and de-RAID them.

RAID 0 stripes the data between the two drives, and neither can thus stand alone. Had you used RAID 1, it would be an easy separation as they are mirrored.

You need to rebuild it in RAID 0, then you have to nuke BOTH drives. This is a good example of why RAID 0 is a loser.

Have you tried completely nuking the separated drive with FDISK or low level format (the destructive type found on most OEM drive utilities)?

You may have to use a SATA to PATA adapter to use FDISK.
