subject: Want to possibly lose your JFS volumes? Multiboot with W2KPSP4 [or X

Hi All ,
Posted to both os2user and ecomstation groups on Yahoo & also to 
os2genau{at}os2.org.au in view of the possible seriousness of the problem, 
so please excuse the multi-posting.

I have been getting cheesed-off at the problem with multi-booting 
OS/2-eCS with W2KProSP4 [could still be the same also with XP?].

Following a "not-as-attentive-as-I-should-have-been" multi-boot to 
W2KPSP4, and not aborting the process in time, W2KPSP4 now "recognises" 
all JFS drives as "FAT", even those >2GB, and tries very, very hard in 
the [now - on every boot] text-mode part of the boot process to "FIX" 
them with CHKDSK.

Definitely not a case to let it boot "unattended" there!  Even in 
"attended" mode you have to be very quick to stop it doing a CHKDSK on 
all those "FAT" volumes, as of course it's idea of
"fixing" them is 
definitely not a good idea!

I have posted an annotated screenshot of the W2KPSP4 interface showing 
the problem, plus another shot from LVMGUI showing the *real* volume 
name of the volume referenced below, on the files-area of the 
os2user{at}yahoogroups.com group.

Following this is a text reproduction of the Disk Management Tools 
display here on one system with a few JFS volumes.
Note that *all* of these volumes, bar one - see below, have had their 
driveletters "removed" in that same interface. This has always been a 
problem with W2KP, especially after any repartitioning/volume changes, 
but it now happens on *every* boot to it.

Most of the displayed partitions are in their physical order as seen by 
W2KPSP4, with "recgnised as valid" partitions [FAT & FAT32] at end of 
list. The exception is the [JFS]volume K, located on Disk #1, which 
somehow W2KPSP4 has allocated a "Volume" label of [HEX-string]
"21 0e e4 
cc 2e 46 18 c7 80 90 c4".

Doing a GU search of that JFS volume it's only found once, in Logical 
Sector Number 561, located on Cyl 0, Hd 9, Sector 58 at offset 0x0060, 
not where an expected volume label should turn up.

The "BOX-characters" in the screenshot replace the HEX values of 0e, cc, 
18, c7, c4 in above string.

There was *no* drive-letter attached to that volume under W2KPSP4, so 
impossible to remove same. It appears that this mutilation is what is 
now causing W2KPSP4 to "find" and identify all JFS-volumes as
"FAT" on 
bootup.

This disk is a "test-bed" so a lot of partitions have their 
volume-letters shuffled in the process, two partitions were badly 
affected [CRCs no longer reliably read in system area of partition] by 
power outage problems prior to buying a UPS for the system, and many 
have variable volume letters, as required.

Noting comments elsewhere about AirBOOT 1.03 no longer using 
Volume-labels, but only Partition names, I wonder whether Martin Kiewitz 
has encountered a similar problem?

* 512MB USB-FLASH drive was FAT, but now JFS too!

** W2K PRO SP4 tries [very, very hard - CAN'T BE LEFT UNATTENDED!]
in the text-mode part of the boot process to FIX these JFS drives
even though they have had their [WIN] drive-letters removed with the
Disk Management Tools in W2KP SP4!!!

Maybe JvW can come up with something in DFSee to fix this problem,
which makes the former IBM BM problem look like peanuts!!
