Help please, I've ruined my ScanDisk Card

Factual Questions
1

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??

What OS are you running?

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.

6

64 bit. I figured if I was gonna upgrade I would do it all the way.

I’ll let you figure out which one you want to try. Good luck.

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

Commandwindows.com has a pretty comprehensive list of things. You can find details about individal commands many places online, and there are some books available.
