It's also much more convenient to run a tool straight from your OS rather than restarting into a custom bootable image, then back into your regular OS again.
On top of that SATA requires the support of hot plugging, so you could in fact connect the TivoHD drive to the computer without the need to shut down at all
GSmartControl is also available on PartedMagic, which is available as an .iso or as part of the UBCD .iso
Or at least it has been in the past, I haven't seen the very latest versions of either.
