Hi! 
I’ve downloaded QNX 6.2.1 and i have a question.
how are the partitions called? What is their nomenclature? How can I mount other partition?
I supposed that I can mount them, as in Linux, with:
mount /dev/name_partition /folder_where_i_want_mount_it
but i don’t know partition nomenclature in QNX. 
[for example if a partition in Linux is called hda1, in qnx what is its name?]
Please, help me!
bye
QNX partitions are type 77, 78 or 79 and QNX6 uses 79 by default for the installation. You can create and mount 77 or 78 for your data/home/other partition.
mount /dev/hd0t77 /home
do a “ls /dev” to find out what you have. and “df -k” to see .
Ok but now i’ve a problem:
I use qnx as live-cd and i want mount a linux partition with filesystem ext3 to /linux.
I do:
mount /dev/hd0t131 /linux
and the computer tells me:
mount: Can’t mount /linux (type qnx4)
mount: Possible reason: Corrupted file system detected
The same things happens with the second ext3 partition (hd0t131.1) and with the ntfs partition (hd0t7)
Why? Are ext3 and ntfs partitions unsupported?
you need to "mount -t type /dev/… " to specify the partition filesystem type. if you don’t, it will default to “qnx4” type and that’s why you got the error:
mount: Can’t mount /linux (type qnx4)
“type” could be nfs, cd (for iso9660), qnx4, dos, ext2, etc.
someone in Russia has been working on a ntfs driver, but the site is currently down:
domo.qnx.org.ru
“ext2” driver should be able to read “ext3” partitions (isn’t that what ext3 is advertised for?) . But to be safe, you should mount it readonly using the -r option to mount.
“use mount” command will give you more details.
I tried, as you have suggested:
mount -t ext2 /dev/hd0t131 /linux
and it works! 
Thank you!
