Use Physical disk

It doesn't matter whether the USB was a disk or flash. Same problem. Just because the Host FS chkdsks OK, doesn't mean that the FS insidewill. Entropy. If it's corrupted in a way that doing a chkdsk /f C: can't repair booting your VM from your XP media in recovery mode, then I think that you are out of luck. If you haven't got a backup then you may still be able to add a second new VDI and in recovery mode, use fdisk to partition it, format it and try to xcopy critical file from your corrupt FS onto this.

I am confused. I can browse the file system and see every file that was created when I installed XP. All the files seem fine. I can copy to the drive and use the drive on my local machine just fine. This same file system is considered corrupt by VBox. This is not a container for the file system, but the actual file system.

dmonder, what if you just create another vmdk descriptor for the drive? And a new virtual machine? Does VirtualBox still complain? What version are you using?

AAAAHH. I've just realised that I've missed a fundamental point. You've got a VMDK mapped raw partition and the raw partition file system is OK. This is not the VDI scenario as I was discussing. So the advice of aquarius is correct. Release the VMDK and delete it then recreate a new raw VMDK using the createrawvmdk as discussed in the User Guide.

Sorry for being thick.
