Guys,

-----------------------------------------------------------------
Background:

Pendrive #A has the same files as #B pendrive.
Both setup the same. Each should run the same.
#A runs MBR, grldr, menu.lst, menu_00.lst, etc., 3 times faster.
compared with #B.

Compared to several other pendrives,
#B runs the bootup routines at 1/3 speed.

My other Puppy Lucid 525 systems run 'grldr' , 'menu.lst', etc.,
with NO 'idlinux.sys' available.

#1 Problem: All pendrives should run the bootup routines at the same speed.

#2 Problem: Cannot delete this unused file, named 'ldlinux.sys'.
(spelled in caps is 'LDLINUX.SYS', so I know I spelled it right.)

-----------------------------------------------------------------

ls ((( shows file 'ldlinux.sys' ))
ls -al *.sys
-r--r--r-- 1 root root 32768 2011-12-09 19:24 ldlinux.sys

rm ldlinux.sys
rm: cannot remove 'ldlinux.sys': Operation not permitted

chmod 666 ldlinux.sys
chmod: changing permissions of 'ldlinux.sys': Operation not permitted

chown root:spot ldlinux.sys
chown: changing ownership of 'ldlinux.sys': Operation not permitted

That drive has had syslinux installed on it. To use it with grub and get rid of the syslinux stuff, then re-format the partition, then install grub and the distro files.

Hi,

Different makes and models of pendrives have different read speeds and especially different write speeds.

Here is an example using USB 2 for source and target and cloning identical data from my OCZ Rally formatted as ext 4 to my faster (and more expensive) Patriot XporterXT and to my slower (and less expensive) Transcend JF V60. All three pendrives are identical sizes.

12/01/12 from OCZ Rally to Xporter 6'04" 10.5 MB/s
12/01/12 from OCZ Rally to JF V60 17'01" 3854 KB/s

You may like to see if you can google any technical read and write speed specifications (or independent test results) for your pendrives.

My regards

Jasper,
Thanks.
These are two Cruzer 16G pendrives.
Bought at same time.
Just figured they would be the same speed.
Did not expect a 3-to-1 speed difference
on the exact same boot-up code.
( I run my main system from #A pendrive.
and #B pendrive was to be an exact duplicate "spare".)

I have been experimenting with artful bootup code.
At bootup,
1) only 'grub4dos' 'grldr' (v. Dec. 2011) is running 'menu.lst'
and loading a splash screen,
2) then calling a second 'menu_00.lst' with no new splash.


#A loads second 'menu_00.lst' in 3 seconds.
Same code is copied to #B.
#B loads second 'menu_00.lst' in 10 seconds.

I have other makes, and as you said, they can run at different speeds.

After I have played with this some more,
I will simply reformat the pendrive, and start over.
Don't expect that to make any difference, but I'll find out.

Guys,
Solved.
Fast boot was with a partition that started at 2048.
Slow boot was with a partition that started at 63.

I guess I "moved" the partion, don't know how yet,
as gParted is very specific about what is allowed or not.

This time, I ran gParted to format ext2,
and was given the start address as 2048.
gParted 'assigned' that start address.
Then I ran 'grub4dos' to install the MBR, nothing else.
Then I simply 'copy' the entire /mnt/home subdirectory
from #A pendrive onto #B pendrive.
Rebooted, switched pendrives in the USB ports
so that #B was in the priority boot slot,
and it ran at full speed.

#A pendrive runs the same speed as #B pendrive.

Thanks for the input.
Still don't know the exact 'why',
but I know how to avoid the problem in the future.

So that is when you gpart it to be ext2
what if one keep them as Fat16 or fat32
as they are when one buy them?

is that slower than ext2?

I am not adventures at all. I usually only use grub4dos
but Pussylinux had an instruction how one can
dd an image to the USB and that way easier get it going.
So I tested that one and I think it was isolinux boot
then I have a grub2 that rcrsn51 made for me.
Lance over at Pendrivelinux made some kind of limited
grub2 thing and rcrsn51 made a pussy variation of it.

I don't dare ask him but something about it can be either
Lance or rcrs51 or nooby doing something outside the
protocol because it fail to show a lot of entries.
So maybe it is me fooling too much with code.
I trust the other two knows enough to not set it up that way.
Sad but whom can I ask why it fails? I have asked in
Beginners but few cared about it.

So there is a lot of booters I have not tested like Plop nad
ext and many others.
