I have been running the same application on QNX4.25 in Compaq ML370 with two
SCSI harddisks (9.1GB each) with AHA 3940 SCSI controller. Recently I
encountered a weird condition where I could not write to any file in the
bootable disk after I have rebooted the system. And it remains the same even
I have rebooted it for several times. chkfsys also couldn’t run. Has anyone
experienced this before? Any suggestion what should I do to make the disk
Writable? Is there any option in QNX4.25 Fsys that I should use? The other
disk is OK. I have tried to move the harddisk to another ML370, but it
remains Read-Only.

There are two things that I can think of that could cause this: the
mount command was started with -r, or there is a jumper on the hard
drive itself to prevent writing. … or #3, the hard drive is defective.
Besides the suggestion to boot from floppy, if you can arrange for it to
be the second drive in a working machine you could mount it by hand and
run scsi_util on it to check for anomalies.
