Booting to Windows 7 has worked in the past. I don't know what changed.

When I select the Windows 7 menu item, I receive the errors:

no device
invalid signature 468CEF828CEF6ABF

Note that I've manually added the Win 7 option to GRUB, since GRUB has never been able to detect my Windows installation.

menuentry "Windows 7" {
  insmod ntfs
  set root='(hd0,1)'
  search --no-floppy --fs-uuid --set 468CEF828CEF6ABF
  chainloader +1
}

Help resolving this error (and possibly getting GRUB to properly detect Windows) would be great.

Boot Info Script (it's too big to paste here)

Is it capable of "containing"/preventing the exploitation of things such as this?

The tray icon for Truecrypt is out of place:

All my other icons are where they should be. How can I fix this?

I'm still learning the command line, and I'm having trouble piping a list of files into graphicsmagick for conversion to pdf:

find . -type f | sort | gm convert file.pdf

This gives the error: gm convert: Request did not return an image.

Can I do this without resorting to more complicated methods?

I would like to create mirrored partitions on a single disk to protect against bit rot. I understand this will not protect against hardware failure.

Seeing as ZFS is intended to work with drives, could there be any problems with using partitions instead?

I've been using the following command line to do recursive checksumming of directories. It seems to get the job done, but still being a newbie I've been wondering, are there any potential problems with doing it this way? Is it possible for this command to miss files or otherwise mess up?

find ./dir/ -type f -exec sha1sum {} \; > files.sha1

hud-service in system monitor is currently using 800 MB of memory. Is this normal? What is it for? Is there a way I can reduce it?
