I have a compact flash card plugged into a USB2 7-in-1 reader. The reader
works fine in windows, and I can even mount the drive under QNX 6.3 and see
the files on it.
However when I try to run fdisk, it freezes…
The CF shows up on /dev/hd2 (and /dev/hd2t77).
I do
fdisk /dev/hd2
or
fdisk /dev/hd2 info
and it simply freezes. (For a long time… hours… I’ve not seen it
unfreeze).
[update: fdisk by itself freezes, after about 1.5 hours fdisk info actually
returned, along with a “cylinderssectors/tracksheads” mismatch (501760 vs
499968…]
It doesn’t respond to CTRL-C, although the OS is fine ; I can get another
virtual terminal.
In 6.1 without USB support, we used to plug the CF cards into an IDE
adapter, and then we could fdisk them no probs.
I was hoping to avoid using that special purpose build rig and just use a
USB adapter on our normal QNX server;
is there anything special that I should do to partition a CF card hanging
off a USB adapter?
I’ve tried this on a Dell Precision 340 and also on a much older USB1
machine ; same symptoms in both cases.
