I am trying to partition and format a 2 GB flash drive. I split it into two 1 GB drives (with HDM 2010) and one is active and bootable and contains my UBD4WIN install and the second partition I was going to use as storage for other files. However, HDM 2010 is having a problem formatting the unformatted partition, each time coming back with an "Invalid Partition ID" when rebooting to complete the process outside of Windows. I also tried formatting with Win Xp but it also is erroring out when attempting to format the remaining space. I am new to HDM, so I don't know any "tricks"! Thanks in advance!
