Title: Partitioning problem.
Post by: ElementCoder on February 17, 2013, 11:17:20 am

I want to shrink a volume on my HDD so I can create another partition. It took very long so I though it wasn't doing anything and shut it down. Apparently I should not have done that because now it says "Logical Disk Manager: Acces denied" everytime after a while when I attempt to shrink. Is there any way to fix this that doesn't involve reformatting? I can't afford to lose the data on this disk.

Ohhh yeah... you really shouldn't have shut it down mid-process.  How long was it taking?
What OS are you using, or is on the partition you're trying to shrink?

Assuming Windows: use the command line tool diskpart

Assuming Ubuntu: Launch disk manager from the command line with sudo

It was going for around 6 hours already. So I assumed it was hanging/not doing anything anymore.

use diskpart (must be run from an elevated (run as admin) command prompt)

gparted is the one Ubuntu uses. And you really shouldn't have done that. It takes a long time to do because data needs to be moved around in order to allow splitting the partition evenly into Used space and Unused space, so a new partition can actually be made without fragmenting the drive.

chkdsk /f (https://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/chkdsk.mspx)

Defragmenting isn't enough by itself. The whole files can still be in the part of the drive you want to split. The process just takes a long time.
