They mean "attempt to access beyond end of device".
To put it another way: Something (probably some metadata on the disk, like
directory entry or control block) said "the inode you want is at this
position", the filesystem said "ok, accessing it now", the device driver
said "hey, that's not anywhere on the surface of this disk"
And well, it's likely to be caused by damaged meta-information (filesystem
structure data) on the disk.
I got it on my swap partitions once because of bad RAM chips, though.
