I hadn't thought about low-level disk access from perl before. I'm familiar with the "everything is a file" nature of the /dev tree under Un*x, but haven't really done much with direct access.

The questions that come to my mind are whether you must/should do such accesses with the partition unmounted, and how you'd go about testing such modifications to sectors of an image which will be mounted as a filesystem. (And what filesystem(s) you're dealing with, out of curiosity.)
