+1 for "mounting itself might write to the disk": I never thought about that (though it's logical in retrospect).

Actually you can mount ext3 without modifying it using options "ro,noload" (from Documentation/filesystems/ext3.txt in the Linux docs). The docs note, however, that this can lead to "various problems"...

@sleske Yet, I'm trying to mount an NTFS system, not an extended one ;)

@BlookPhilia: I'm fairly certain noload is specific to ext3. No idea if there's an equivalten for NTFS.

"Disks and partitions are only accessible by root unless you've explicitly changed this" Not entirely correct. With the capabilities system, a process can have access to raw I/O while still running as a standard user. However, with a standard kernel and base system, the only thing that can grant capabilities is processes run by root. In other words, only root has CAP_SETPCAP.
