VBoxManage throws an undescriptive error when trying to resize a VDI downwards

Bug: When trying to resize a VDI to a size smaller than its current size, VBoxManage throws the following error:

"Progress state: VBOX_E_NOT_SUPPORTED VBoxManage.exe: error: Resize medium operation for this format is not implemented yet!"

This error doesn't actually tell you the VDI is too big of a size for this operation. What's worse, trying to resize a fixed VDI or an actual unsupported file format throws the same error, so you have to guess.

How to reproduce:

Create a VDI

Run the command "VBoxManage modifyhd <nameofvdi> --resize <size>", where <size> is smaller than the size of the VDI and <nameofvdi> is the name of the VDI.


Change the error message to read "Resize medium operation for this VDI is too small a size!" or something to that sort.

I'm having the same problem with Windows guest 5.2.22

I'm not able to shrink the VDI file and i can't understand why.

I've looked at #9103 but in my case i already deleted all the snapshot. So i'm probably falling in a different case

Replying to palminha:

I'm not able to shrink the VDI file and i can't understand why.

Because if you read the description of the ticket, it is known that you cannot shrink a VDI. It's not supported. Only enlargement is supported.
