Dosfsys problem

When my OS is QNX 4.25 start then it drop drive a in dos folder. so i
can’t use Dosfsys then drop Dos partitions for use in QNX.
In /dev i have
hd1.0t6.1 and hd10t77
with hd10t77 is QNX partition so i use mount statement:
mount /dev/hd10t77 /hd2
it is OK
with hd1.0t6.1 is Dos partition so i use Dosfsys:
Dosfsys c=/dev/hd1.0t6.1
then it isn’t run and error is /dos exists. I try:
Dosfsys /dos1/c=/dev/hd1.0t6.1
then it isn’t run.
How do work with it ?

DosFsys has been deprecated, try Fatfsys instead.

This sounds like Dosfsys has already been started in your startup
(.sysinit), and you can’t start it twice (the “/dos” exists error).

You could remove it from the sysinit and start it by hand after
mounting your hd1 partitions, or move the mounting of the second
hd into the sysinit before Dosfsys.

Also consider replacing Dosfsys with Fatfsys (which supports FAT32).

Yuo can first run “Dosfsys -x”, then run Dosfsys
c=/dev/hd1.0t6.1.
