I recently installed Chromium OS (Hexxeh's vanilla build) on my 16 GB flash drive.
Later on, when I tried to format it, it was showing a total space of 1 GB. I tried deleting partitions in disk management, but I was only able to delete some of them. It was then showing free space of 16 MB.
For one partition, when I tried to format it, I got the following error:
An unexpected error has occurred. Check the System Event Log for more information on the error. Close the Disk Management console, then restart Disk Management or restart the computer.
The following images show the partitions that I cannot delete:
What can I do to reclaim the full space of my flash drive?
