I am trying to install QNX 6.4.0 on PC 
PC is equipped with SATA hard disk. windows 7 installed in first 400 Gb of disk, next 100 GB un-allocated for QNX 
partition. 

1) After I select "Install to hard drive" option installer writes on screen: 
... 
Trying SATA ahci. Scanning for devices... 

Trying EIDE. Scanning for devices... 
... found 2 devices 

Detected USB. Scanning for devices... 

Trying SATA mvSATA. Scanning for devices... 

Hello there,

Started installation is interrupted with message on screen: 
"unable to access /dev/hd0t179 
Mounting filesystems... 
Partition installation aborted! 
Please remove the installation media, then reboot your machine" 

It is interesting that QNX file system is created on hard drive when I look at disk partitions using disk partition tool
 after reboot. 

I read a thread said a solution is enlarge the exsiting patition,but I don't understand what is this meaning?http://

Can anyone explain this solution or any other solutions?? 

Many thanks in advance!
