Problem seeing my created partitions
« on: April 07, 2007, 11:49:43 AM »
Have hooked up an external Lacie 50gig SCSI hd to my A3000 SCSI along with my trusty external scsi cd-rom
The problem is that after creating partitions on the 50gig hd with PFS3, PDS3, SFS and FFS the partitions aren't shown on the desktop after a reboot and I can't even format them with sfsformat or pfsformat using shell.
Running OS3.9 & BB2, have the latest WD scsi chip also

Here's some dumps from hdtoolbox

On the screen shown in the second picture, click on the Quantum 4GB drive and see what happens. If a requester pops up telling you that drives have been added or removed, let it save the changes.

and when you have fixed the issue, rise the dosbuffers from 80 to 400 (at least) for every SFS/PFS partitions.


I always use at least 500 buffers on my partitions, have plenty of RAM to waste on it  :-D

As a start you could give the partitions some meaningful names. For example these are mine: Workbench, Work, Text&Data, Programming, Games, Internet, Emulators, Music, Graphics, Pictures, Backup, Cache and CD-Images.

hehe, just wanted to salute my Lacie ext. SCSi disk now when everything works  :-D

I can disclose that two of the partitions will be called "Games"  ;-)

Thomas, what actually caused the partitions not to be shown?

Performance optimization. Each HDD has a flag "this is the last HDD" in its partition table. At boot time, when the SCSI driver reads the partition table of each drive and sees this flag, it does not continue to search for other HDDs. In your case (without the new HDD), the 4GB HDD had this flag set and thus the CD-ROM drive was not checked for partitions. This feature should decrease delays at boot time.

Now with the new HDD connected, the flag on the old HDD had to be reset so that the new HDD is found at boot time (now the new HDD has the flag set, it's done automatically by HDToolbox).

Bye,
Thomas


Ahh...thanks for clearing that up  :-)

It's great to know the "cause and effect", I'm a guy who can't sleep if I don't know the cause of things  :crazy:
