Drive Stuff
Event hard-drives aren't safe from eggs.
Signature Byte
SigBytes identify the Boot Block. $4C4B signifies that you have a bootable Macintosh disk. "4C4B" translated in ASCII means "LK". This stands for Larry Kenyon who originally designed the Mac's File System.
Disk Type?
Your disk has a "type" to tell it what type of Mac disk it is. (Is it MFS, HFS, HFS+, and so on?)
Well they are only two bytes (characters) -- but you can cram a lot of meaning in a two letter acronym.
- An MFS volume is $D2D7 which is ASCII "RW" (Randy Wigginton).
- An HFS volume is $4244, which is ASCII "BD" (Big Disk).
Anyone know what HFS+ is defined as and what it might stand for? (I suspect it is still just the same as HFS).
Hard Drive Part Number
On some computers (mostly older Macs;it worked on a Centris 610), the Part Number for the internal drive is listed as "The HORROR Continues". You can find out if your computer says this by downloading the file "Slot Info". There is some suspicion that this may be a glitch in the program Slot Info.
