As requested:
| Code: |
# grep 'sr0' /proc/diskstats
11 0 sr0 0 0 0 0 0 0 0 0 0 0 0

Keef, that output is as expected.
Dunno for now the real reason, have such output, too, often after the fd0 drive.
I thought that the kernel might have refreshed the /proc/diskstats file.
It happened always only the first time it had run, the second and later runs had no problems.
But wjaguar showed me a better use of the read buildin, and that seems to be robust:
Instead of
| Code: | while read line; do
echo $line
#do a lot of awk here to get third and second value
done</proc/diskstats |
the use of
| Code: | while read maj min drive rest; do
echo $maj $min $drive
#no need for awk anymore
done</proc/diskstats |
has not failed anytime for me now.
This is also faster without the need for awk.
Will change the script in post 1 now.

Current version:
| Code: | # probepart
/dev/sr0|none or not inserted|8589930496
/dev/sda1|ext2|100677169152
/dev/sda2|ext2|92249522176
/dev/sda3|ext3|114956513280
/dev/sda4|swap|12173414400
/dev/fd0|none or not inserted|32768
/dev/sdb1|ext3|32440246272
|
Pmount is showing the CF card correctly, and the optical drive is now being detected once a disc is inserted.

Update :
* Made it work in ash .
* Use of case instead of the many [ ] tests for the options.
* read shell builtin function instead of external cat.
* Changed logic to enable output also for -d/dev/sda ( whole single drive - was for -d/dev/sda1 partitions ) .

###INTRO
# Karl Reimer Godt, March-May 2013
# /sbin/probepart originally written by
#
# Barry Kauler www.puppylinux.com
# LGPL 2007 Puppy Linux www.puppylinux.com
#
# Different code for /sbin/probepart
# that is used by
# /sbin/pup_event_frontend_d
# ,
# /usr/sbin/pmount
# ,
# /usr/sbin/partview
# ,
# /usr/local/bin/drive_all
# and
# /usr/sbin/shutdownconfig
# and probably some more .
#
# May output fat as Fat[16|32] by disktype, not as vfat
# so take this into account if these scripts don't
# show your fat partitions.
# Also omitting the /root/.usb-drive-log-probepart file
# , the forcing of USB by
# dd if=/dev/$ONEUSBDRV of=/dev/null bs=512 count=1 >/dev/null 2>&1 #v3.97 faster.
# and unfortunately
# /usr/lib/mut/bin/guess_fstype
# since the developer jesse had not ported it to support ext4.
#
# Thanks very much to Keef for patience while testing and
# helping me detecting some wrong formatted code, confirmations
# and to keep pmount happier.
# Thanks muchly to wjaguar to remind/teach me to use the read command more effectively,
# which solved problems posted by Keef and also encountered by me, and did
# increase the speed reasonably.
# Also thanks to Ted Dog for reporting about network-block-devices (nbd.ko)
# and headfound for company.

PARAMETERS:
-V|--version : showing version information
-H|--help : show this usage information
-A|--all : show all disks noted in /proc/diskstats like ram|loop|mtd|md
##edit1: added following size formats:
-b : show size in bits (default)
-B : Bytes
-kb : 1000-kilo bits
-mb : 1000-mega bits
-gb : 1000-giga bits
-kib : 1024-kilo bits

-GB : 1000-giga Bytes
-KIB : 1024-kilo Bytes
-MIB : 1024-mega Bytes
-GIB : 1024-giga Bytes
-k : show sizes in kilobytes (KiB) #compat.
-m : show sizes in megabytes (MiB) #compat.
Without one of the above parameters it is the value found in
/sys/class/block/drive/size
; usually as blocksize=512 formatted to bits .
-d/dev/sdaX [/dev/sdb ..] : output only for given partitions/drives
