Hello
I'm new to qnx, just started using it for a project at work.
I want to partition and format a flash card.
I currently have the flash card connected to a USB flash read and have QNX 6.3 installed.
I terminal and do fdisk /dev/hd10
I get the window and i set it for type 77, and have the entire card formatted.
I then do fdisk /dev/hd10 show and it shows the disk is formated.
Once I do anything else, the card is not partitioned anymore.
Say if i take it out of the USB read or unplug the USB the card does not show it formated.
I started to wonder if I had bad flash so i put it into windows and let windows format it. I then took it back to qnx...and it shows there is a partiotion
I then use fdisk /dev/hd10 and set it up to be a QNX type 77...and it works.
I can change the partition to any kind of format and it will stick.
I would like to know how to do it all in QNX so i do not have to format in windows to by-pass this problem.
Thanks
Eric |

Thanks for your help.
Let me clearify this alittle more.
I would do fdisk /dev/hd10
I would set it up for type 77 and have the entire flash memory set for the partition
After fdisk is done Then I do fdisk /dev/hd10 query or fdisk /dev/hd10 show i get prompts back seeing that that there is a prtition
If I do ls /dev/hd* only hd10 shows not hd10t77
So I can not do dinit since there is only hd10 not hd10t77.
When I unplug the card from the read/or unplug the USB or turn off the pc.. and do fdisk /dev/hd10 show it shows there is no partition on the flash.
Only ways for me to get a QNX partiton on the flash is to bring the flash into windows and let windows format the disk. When I then bring the flash into QNX and run fdisk and change the format to QNX 77 the partition is saved and will show up as hd10t77. |

Hello Eric,
Most likely this problem is related to the specific device you are using.
I tried fdisk with the Imation iCON USB stick and everything works as expected.
USB flash devices don't necessarily have to have a partition table.
Try something like
dinit -hp /dev/hd10
mount /dev/hd10 /test
reboot and mount again.
Thanks,
Yuriy |
