TestDisk & PhotoRec: nice tools to recover lost partitions & files

TestDisk + PhotoRec is a nice toolset to recover lost disk partitions (or at least rescue some files from corrupted filesystems) in case of storage media failures, re-partitioning errors etc.
Works for disk images too.
More to say, it's a free & open source (GPL v2+) cross-platform (Linux, *BSD, Apple Mac OS X, Oracle / Sun Solaris, MS-DOS, MS Windows) software.

Presently, in Debian-based Linux distros, TestDisk & PhotoRec have been packaged into a single testdisk package, so you can install both tools at once:

# apt-get install testdisk

Acer Aspire 3810T (AS3810T): laptop LCD panel (screen) replacement compatibility list

Some of the Acer Aspire Timeline 3810T (AS3810T) laptops have specific LCD panels which often have backlight broken after some operation time (it's caused by a "flex strip"-type powerline bending breakup -- look at that blogpost for more info and pictures).

If your laptop is already out of warranty, you can buy a new LCD screen and replace it yourself.

• Acer 3810T laptop commonly uses a 13.3" LCD screen [1366 * 768 WXGA; 18-bit RGB (3 * 6 bits) -> 262144 (2¹⁸) colors] with LED backlight and 40-pin connector.
• Pay attention to the specific brackets it has, as some display variations will not fit.
• To prevent future problems, try to get a display with no such overbent "flex strips"; in this list, I've marked supposed "fragile flex" displays with a [bent flex] label.
• Anyway, better don't buy a display without checking the actual part numbers and product photos (and also datasheets, preferably).
