HDa vs HDb: Difference in Pin Settings & File System

[Shawnzyoo]

So I got into an argument with a buddy over the following:
I originally inserted a hard drive into my system and it was labeled hda, what i hadn't notice was that it was on the master pin setting
now when i switched the pin to the slave setting and rebooted it showed it as hdb
are the two related? or completely unrelated and just a coincedence?
how does the file system see the different pin selections (if it sees it at all)?
Thanks

There is nothing wrong there. This is a naming convention that linux uses to assign labels to IDE drives.

hda primary master
hdb primary slave
hdc secondary master
hdd secondary slave
