I need to increase my 20G vdi to 80G and it seems to not be working.

I have read the post at viewtopic.php?f=35&t=50661#

I am not using a fixed drive or snapshots as far as I know.

When I issue the vboxmanage on the command line as described, the vdi file doesn't change.

How do I do this?

Do you get an error message? Do you see a progress bar and 100%?
Did you see the second step in the link?

Yes I see a progress bar. It never populates. No error message. You issue the command, the progress bar shows for a second, then back to prompt. Certainly not long enough to increase from a 20G vdi to an 80G vdi.

Seems like second step is moot if the first step isn't completing. Regardless of the partition expansion in the second step, I should wind up with an 80G vdi file from step one, which as I stated, is not happening.

Unless there is some magic undocumented thing that I can find no reference to that the vdi file will only "grow" after step 2 is completed.

Can you please post the output of:

VBoxManage showhdinfo <uuid|filename>

as well as your exact command AND its output when you try to resize your HD with:

VBoxManage modifyhd <uuid|filename> --resize <###>

Resizing only involves rejigging the header and maybe moving a couple of blocks. It should be nearly instant.

It isn't comforting that you aren't using snapshots - as far as you know. The symptoms suggest that may not be correct. Best provide that info Socratis has asked for.
