I tried experimenting with the Google OS, on two flash media cards, a 2 Gb ScanDisk and a generic 4 Gb usb. The Google, or Chrome OS doesn’t work very well for me, so I formatted the two and left it at that. Now both devices only show @250 MB for either one. So, can I fix this? How? I am Googleing for an answer as well, but so far I keep bringing up how to install an ISO, nothing on how to get rid of it. Greatly appreciate any help, Thanks. ---

Just an update, I opened the disk management, and found that I evidently have a 1.6 gig partition, that is unallocated, and the 250 MB is the healthy primary, but the managers selections are all greyed out, so I can’t make a primary or secondary partition, and I can’t erase or expand the partition that is showing up. Any Ideas. Is there a different partition manager somewhere I could use?? ---

Sorry, Windows 7, I am trying to figure out how to use diskpart in the cmd window. currently having no luck. It seems I figured this out in dos once upon a time ago. If I am doing it right, then it must be different now. ---

32 bit or 64 bit. It’s easier to find programs for 32bit only. ---

Well, I think I figured out diskpart. I seem to have a healthy 2 GB primary partition on the disk now, I just have to remember how to do it one more time, if I could figure out where the heck my 4 GB usb just wandered off to. Thank you for the help though, I will check through the list and see if there is something a little easier to work with. ---

Start a CMD window as administrator. “diskpart.exe” “list disk” “select disk x” where x is the number of the flash disk “list partition” “select partition y” where y is the number of the partition you want to delete “delete partition override” “exit” ---

I actually used the clear command, and wound up with a completely unallocated disk, which I then reformatted with the disk manager, I gots all my bits, or bytes back on both disks now. Thanks for all the responses, just as an add on though, can anyone point me to a really good place to learn how to use the cmd console. Something that I can look up and peruse before I actually go and bother other people? Thanks ---
