Changing Win10 Guest Drive letter triggers I/O Error

Reported by: peterg4000 Owned by:
Component: virtual disk Version: VirtualBox 5.0.20
Keywords: Cc:
Guest type: Windows Host type: Linux


I have a secondary virtual Hard disk in my Windows 10 guest under an Arch Linux Host.

The secondary drive comes up as E:\ in my guest, but I would like it to be D:\

With the Virtual CD-ROM drive disabled via VBox (Just to simplify things), in the Windows Guest I use the usual Windows 'Disk Management' tool to change the drive letter.

There is a standard Windows message about the danger of changing a letter, then when I click "Yes" Virtual Box instantly throws an I/O error.

Here is the contents from clicking 'Copy' in that VBox error window:

An error has occurred during virtual machine execution! The error details
are shown below. You may try to correct the error and resume the virtual
machine execution.

The I/O cache encountered an error while updating data in medium
"ahci-0-1" (rc=VERR_DISK_FULL). Make sure there is enough free space on
the disk and that the disk is working properly. Operation can be resumed

Severity: Non-Fatal Error

I will also attach full vbox log.

No, I do not have any full disks anywhere to be seen.

I have to virtually power-off the box to recover.

The drive is back on E:\ after restart.

Is this use-case expected to work under VBox? I can't see why not...

Well, the error message means that VirtualBox tried to write to the disk /HDD-WD1TB and got the error code that the disk is full. Did you check that this drive has enough free space?
