You'll have to go back and redo your partitions (which means reinstalling the OS if you don't have something such as Partition Magic). Be sure to stop the first one at the 137GB mark, and then make another one to pick up the slack. You can set up a simple software RAID configuration later to make it all appear as one partition to the OS or just leave it as two different partitions that show up as different drives. The choice is yours, but you have to do one or the other to reclaim that space.
My HD crashed and I bought a Western Digital 160 GB drive. Because I had an Upgrade version of Windows XP Home, I had to format and partition with ME and then upgrade. In the process, I had to limit the size of the formatting to 137 GB (I had to go FAT 32 while formatting, but converted this to NTFS when finished.
Is there a way to "reclaim" this lost storage?
