Ahhhh ... I think I get it (hardrive labeling)

Hi. I have the ASUS A7v133 that has 4 IDE connectors on the motherboard. After doing a 'dmesg' I think I now understand the labeling system.

My first IDE (ATA66)

------- Primary ---- hda
---- hdb

------- Secondary ---- hdc
---- hdd

My Second IDE (ATA100)

----- Primary ---- hde
---- hdf

----- Secondary ---- hdg
---- hdh

I have FOUR 'IDE' connectors on my mobo in pairs of two.
Each connector can have TWO devices on them.

Am I right in all this?

PS I thought hd stood for harddrive. I noticed it's also used as partition labeling. So hd is used for partition labeling AND device labeling?

thanks

Yep - but for IDE devices. SCSI uses a different naming convention.

You got it. Just remember that in Linux everything is considered to be a "file" -- even hardware. Thus your primary IDE master hard drive is identified to a device file called /dev/hda ... and so on.

EVERYTHING is a file
ls -lh /proc/kcore
your memory
