comment What is the recommended way to empty a SSD?
If you are wondering the difference between blkdiscard and the hdparm command, it is answered here: "When you use blkdiscard, the SSD (assuming a SATA SSD) will receive an ATA TRIM command, whereas hdparm --security-erase will issue an ATA SECURITY ERASE UNIT command. What the drive then actually does is dependant on the implementation details of that particular SSD's firmware."

fstrim is mentioned in this blkdiscard post, you can also invoke it manually with sudo fstrim / (where / is a mountpoint of a filesystem that supports the discard option).

comment airmon-ng is not working?
Have you reviewed common documentation? I found at least two other AU questions about the airmon-ng suite, airmon-ng documentation and dozens of other sources. First, check whether your hardware and driver supports monitor mode. Second, post more helpful error messages.

comment Why is Rsync copying the same subset of (unchanged) files every time?
Aw, fix that destination filesystem then :D Perhaps the --fuzzy option will also help here since the file sizes are identical.

@NickTheSwede The -c option must obtain a checksum of a file so it has to read the full file rather than just look at the size and date. Perhaps you could combine it with the mtime/size comparison, have a look at the manual page. Are you really sure that the files are not modified? What happens if you run the command twice in a row?

comment Why is Rsync copying the same subset of (unchanged) files every time?
I encountered similar issues when syncing from my phone, or to an external disk. Is the filesystem always unmounted normally? If you remove the drive early, it is possible that not everything is written to disk. Oh, another possibility is hardware failure (bad sectors, bad RAM). By the way, you can use --exclude='**/.AppleDouble/' to ignore that directory.

comment Linux headers generics
menu.lst is GRUB 1, modern versions of Ubuntu use GRUB2. Try reinstalling your bootloader and it should pick up grub.cfg with the newer kernel.
