which file in /dev is my windows drive
 

hi
I m using dual OS in my system.
I want to mount windows directory in linux.
I know mount command is there.
But i don't know which file should be given as input?
I mean how would I know /dev/hda1 or (/dev/and which file) indicates C drive?

depending on what harddisk you installed your Windows:
Is it an IDE harddisk on IDE 1 Master it could be "/dev/hda1"
Is it an IDE harddisk on IDE 1 Slave it could be "dev/hdb1"
Is it a SATA harddisk it could be "/dev/sda1" or "/dev/sdb1"

Just try, and you will see what works, and what doesn't...

login as root (with environment)
run:
that'll list your partitions, from there you can work out which it is by filesystem type and size.

If you get errors try
or /dev/hdb etc.

that's for IDE, for SATA replace hd with sd
