Re: I was asked once to resize a virtual machine image.
Poor design on Qemu's part. It should check if data is going to be lost as a result of the command and require a '-force' or something like that. At the very least be smart enough to know that no useful VM can be 160K in size.
Not that this excuses any admin from using a command he's obviously not familiar with without checking the man page first to be sure of what he's doing.
