Hi Rev:
I have to correct myself. pdisk defines each sector block as 512
bytes, not 512K bytes. You can read more details here:

-8&oe=utf-8&client=firefox-a&rls=org.mozilla:en-US:official
The "base" is where the mount point for a sector begins; the length is
the amount of blocks in that sector.
Best wishes...

Hi Rev:
I think I mentioned elsewhere that Linux can only read hfs+ and
read/write hfs.
Refer to:

pdisk is tricky; you have to learn to think as it does where each
sector is 512K blocks. Also what it refers to as length is the where
the mount point begins from one sector to another. Also you have to
remember to convert from blocks to MGs and Gigs. Of course, the
computer can display this automatically, but you won't understand it
unless you comprehend the calculations behind the lablels (and why
those values are either correct or not). Indeed, understanding the
nuances better enables you to partition your drive more efficiently as
well. You can download the manual for YDL 4.0 and YDL 3.0/3.0.1 which
discusses a bit about it. Read as much as you can:

Unfortunately all any OS X or OS 9 (or any other Apple utility) can do
is erase and format the drive either in hfs or free format. pdisk and
another application -- called parted -- I believe -- can create the
ext3 file format Linux understands. pdisk can write over hfs or free
format. pdisk can read and write to hfs, but there is little
usefulness in that as most work will be done in Linux eventually.
In other words, no Apple utility can create or read ext3 file format
which Linux uses. You will just have to dive into Linux and "let go"
of Apple utilities. It can be done.... trust the Force, Rev. :)
Best wishes...

Thanks again, Derick.
The move to 4.0 went well on the iMac 233. Granted it took a
little bit of time with the speed of the processor and all. But all in
all, very smooth. Can't get the screen centered though, it's a little
too far left.
I tried to mount the usb drive like this after making the folder sam
mount /dev/sda1 hfsplus /mnt/sam
and
mount -t hfsplus /dev/sda1 /mnt/sam
neither worked. It said hfsplus was not supported by the kernel.
Also I tried pdisk. It seems like a nice app but I don't know about
block and length settings.
So I reformatted the using os x as Mac os extended (not journeled).
Hey just a thought but can use disk utility to format the drive to
something ydl will be able to mount? Also, I have a machine running
OS9, could I do something with Drive Setup?
Thanks

Hi rev:
Unfortunately moving up to YDL 4 will not be so simple with the
hardware you have. You will have to change your BootX settings
specifically for YDL 4; it may be best to follow the instructions
discussed here:
http://yellowdog-board.com/viewtopic.php?t=249
You can also go to to this link on Google for other topics related to
this problem:

THANK YOU so much for your help and time.
i tried:
tail -f /var/log/messages
and it seems my kernel doesn't support usb devices. So I'm
downloading
the iso's for ydl 4.0.
I'll try that and keep you informed on my progress.
Again thanks so much

Hi rev:
I'll assume you read and had no trouble understanding the previous
links I recommended to you. From there once your drive is mounted
all
you need to do is use pdisk to wipe out/erase your USB drive so
that
it
is formated for use as a LInux drive. That's it, of course you are
clear that you'll have to set mount points for the USB drive, a
name
and create a directory within /mnt using that same name. So let's
say
the name you choose is charles. Then:
# cd /mnt
# mkdir charles
From then on when you mount that drive you can do:
# mount /mnt/charles
and that should be it.
Best wishes...

Hi again and special thanks to Derick,
I'm running YDL 3.01 on my iMac 233 with kernel 2.4.22. I want to
an
external usb drive I have for more storage since the internal iMac
drive is only 4.3G. The drive has some things on it from os x
that I
know longer need. What do I have to do make this USB drive work
with
my linux box?
TIA and have a great day
Rob
