comment How do you find out a laptop screen panel manufacturer / model with Linux? (Samsung, LG, Chi Mei, etc)
Thanks fpmurphy, That log file did have a reference to the panel in there. Interestingly, a Windows program called HWINFO64 seems to give a much more detailed description of the monitor "AU Optronics [model number], etc" but the Linux Xorg.0.log file has "AUO". I wish I could find a similar program to HWINFO64 for Linux.. Still marking your answer as accepted since I can at least use it as a clue and it does indicate the brand. Thanks!

comment What makes a Partition Table valid?
Ken, thanks for your response. So according to this: en.wikipedia.org/wiki/Master_boot_record#Sector_layout The "Boot Signature" is 55h AAh in byte positions 510 and 511 (indexed starting at 0). So, what you've said makes sense to indicate whether there is valid boot code to execute. Your mention of the OS trying to interpret the partition table itself regardless of it making sense pretty much coincides with what I was guessing; I'm now on a quest to figure out what Linux specifically is keying off of to think my drive has partitions. Accepting your answer - thank you!

comment Can random data from a wipe or encryption of a full drive result in fake partitions appearing in the MBR?
Thomas, that's what I was thinking too... statistically unlikely --- except in my case it's happening quite consistently (at least 5 times in a row with different partitions arrangements showing up using certain tools). However, that seems to only be recognized by Linux (while watching /var/log/syslog) and Truecrypt. Other software such as partition management software doesn't seem to show the partitions, nor does the linux command "fdisk -l". Thanks for your input.

Interesting.. I'm trying to think how that could be interpreted by the OS as partitions. I did use a hex editor to analyze the first 512 bytes of the drive itself and there doesn't seem to be the proper signature in the last 2 bytes (bytes 511 and 512) of the MBR.. Possibly what you're referring to is the first 446 bytes of the MBR where you can store boot code, etc? If so, that shouldn't represent partitions. Bytes 447 through 510 store the partition table (16 bytes per entry for a total of 4 entries = 64 bytes). For all I can see, it's entirely random data.

I've also used Truecrypt for quite a long time, but encrypted partitions, and not a full drive. Only recently did I decide to encrypt the full device (no partitions at all). It just seems plausible in my mind that random data might be interpreted as a partition table --- but, if so, I would imagine every drive would have an equally likely chance of this occurring. Likewise, I would imagine everyone that wipes a drive would notice this odd occurrence as well..

Well, technically the flash drive shouldn't have a truly valid MBR either since I first wiped out all partitions on that drive too prior to encrypting it.
