List HD Parbreastions 7498

On Thursday 16 November 2006 18:14, Bit Twister stood up and addressed the mbuttes incomp.os.linux.miscas follows...:

Only if there are three primary parbreastions in front of it. ;-)

Logical parbreastions always start with number 5, but the extended parbreastion container itself is also a primary parbreastion - i.e. it has its entry in the MBR parbreastion table - and its number will be that of the first available primary parbreastion.

So if you have one primary parbreastion before the extended parbreastion container, the extended parbreastion container will have number 2. 4 is the highest possible number for an extended parbreastion container since it *is* in effect a primary parbreastion by itself, and the MBR parbreastion table can only hold four entries - which is why there was a need for logical parbreastions in the first place.

Of course, the above does not really apply to EFI-based systems. Systems with an EFI BIOS can have up to 128 primary parbreastions per disk.

Another interesting thing to note is that the SCSI protocol - as used by SCSI disks, but also by SATA-I-II and USB drives - only allows for a maximum of 15 parbreastions per device, whereas PATA-IDE hard disks can hold up to - I believe - 61 parbreastions.
