More than 4 primary partitions? - Page 2

uhm... no

DRIVES are assigned letters... such as hda hdb hdc or sda sdb sdc partitions are always assigned numbers, logical partitions are always 5 and up and primary/extended partitions are always 1-4
Kinda meh now...

This.

Kinda wish they'd be named after their mount points though, I always forget which number is which, lol

hm... thought there was a way to do that...

WELL once you figure out which partition number it is you can always symlink it in the dev folder like /dev/windows > /dev/sda1

that way you can mount /dev/windows /mnt

drive letters will actually change if you put more drives in the system though so if you do that just pay attention if you change your set up
Kinda meh now...

You can do this dynamically with udev rules. You feed it some drive specific parameters (model number, manufacturer, etc) and it will create your specified symlink for you (you can do many other things too). Also depending on your kernel configuration /dev will be a ramdisk that gets recreated and populated during boot so links may not stick.

The easier way if you have Linux formatted drives is just to use partition labels. You can label ext2/3/4 partitions running
Code:
e2label /dev/sda1 name
Other filesystems including swap support labeling too using fs specific commands. Once labeled you can reference the partition as "/dev/disk/by-label/name" or "LABEL=name".

So there are some good ideas listed in this thread but they are all way to complex for the basic purpose of what you are trying to do. Just use LVM thats what it is for.

Here; a full guide on how to use it.

So much bad information in this thread...


1. Windows requires a primary, Linux doesn't.

2. Letters denote physical drives, numbers denote partitions. /dev/sd*1-sd*4 are primary partitions, and /dev/sd*5 is your first logical, so even if you only have 1 primary partition, the first logical partition will still be /dev/sd*5

Linux doesn't need a primary partition though.

The system needs one, but Linux doesn't.
