Can't get rid of the unallocated space in my flash drives...

post #1 of 6
Thread Starter 
So I've been fooling around with a couple of my flash drives to install some USB loading linux OS's. But for some reason, when I formatted, it took my 2 gig flash drives and turned it into a ~180 meg flash drive.. So I went into disk management, and it looks like the rest of the space on both is unallocated. Now, I can't figure out how to create one partition that is full sized... I can't extend the volume, or delete anything. I know there's a way to do it but I'm just having a brain fart.. Any help would be greatly appreciated.. Thanks!

you can manually repatition the flash drives in command prompt but you'll most likely loose anything you have in them..

so move anything that's important

directions when in command prompt (make sure to run as admin)

· type DiskPart, Enter key
· type List disk, Enter key
note the numeral of the disk you want to clean
for example purposes, I’ll be using the numeral 0
· type Select disk 0, Enter key
· type Detail disk, Enter key
this info will let you know if you selected correctly
· type Clean ALL, Enter key
your entire disk is being overwritten with zeros.
This can take a considerable amount of time
· type EXIT, Enter key (only after Clean is finished)
· type EXIT, Enter key (this gets you back where you were)

This, but do not do clean all, that's not necessary. If you just do clean, it will only wipe the partition map, which takes seconds, and then you will have 1 large chunk of unallocated space where you will be able to create a partition in disk management.

I tried your solution and i got that error

DiskPart has encountered an error: The media in the drive may have changed.
See the System Event Log for more information.

Please help
post #6 of 6
Have you tried using Diskpart to extend them? If so, what error does it give? Maybe try running chkdsk /f on each as well, if you pull the drive out and stick it back in does windows ask to repair them?

edit: just realized was an old thread, ma bad.
