Hello, 
I'm new to the forum and I thought I posted this already but I don't see my post added to the list, so hopefully this is
 not a duplicate.  I'm desperately trying to just create a QNX partition on a hard drive but I always get "Corrupted 
file system detected".  I've installed the QNX SDP 6.5.0 on my x86 Advantech PCM-9389 onto the primary SATA hard drive 
via the SATA CDROM.  I replace the CDROM with a new SATA hard drive. Then observe the new drive is mounted on /dev/hd1. 
 Then I:
1) fdisk -z /dev/hd1 to zero the partition table and enter interactive mode.
2) I change partition 1 to type 79, start at cyl 0, end at 4799, set the partition bootable, save, quit.
3) mount -e /dev/hd1
4) fdisk /dev/hd1 show  this shows the drive as expected:
QNX type 79 start cyl 0 end 4799 size 37652 MB  * (bootable)
5) I restart the system via "shutdown" command expecting QNX to automatically detect the new drive and partition and 
mount it for me.
6) I see "mount: Can't mount /fs/hd1-qnx4 (type qnx4)"
             "mount: possible reason Corrupted file system detected"
I have also tried manually mounting  after step 4 via "mount -t qnx4 /dev/hd1t79 /fs/hd1" and I get the same error as in
 step 6.

Please help and my apologies if this is a duplicate post.  Thanks,
Eric Franz
