Windows 7: Trouble formatting secondary drive.

I just placed an old hard drive into my computer to use as a slave. After I booted up on my current hard drive I went into disk manager and tried to format all the partitions. I formated one easily but the other won't seem to format. The option to format or delete volume are both greyed out.

I then tried to boot from my Windows 7 disk to format the drive that way but it said it could not format dymanic drives. I can't change the drive to basic without deleting the last simple volume.

I'm stumped on what I should to do to make this work. Any suggestions and/or help is greatly appreciated.



Thanks.

Use diskpart clean command - make sure you are pointing at the correct drive.

From an elevated command

diskpart

lis disk

sel disk #

clean

exi

make sure you use the correct disk number in place of # above.

I tried that as well. It said: Clean is not allowed on the disk containing the current boot, system, pagefile, crashdump or hibernation volume. I don't understand how that is so if I'm booted on the other hard drive.


EDIT: I managed to use the cmd clean prompt by running my cmd before actual boot. This allowed me to wipe my secondary drive even with all the other errors I was previously getting while trying to do it during windows.

Glad you got it working - thanks for the update.
