Drive Image 2002 Slower transfer rates

I have two computers running Drive Image 2002. The transfer Speeds
when making and image are dramatically different. My older computer
is actually faster than my newer one. How can this be? Here are the
spec's for both computers.

P3 450 slot one
768 mb ram
12 gig (5400) primary drive
40 gig (7200) slave
windows xp (not that it matters, i think)
transfer rate is 359mb per minute.

the other computer is...
amd xp1600
epox mobo (via chipset)
ibm deskstar (7200) 20 gig primary
ibm deskstar (7200) 40 gig slave
512 ram
transfer rate 195mb per minute!

this is a transfer that is set up in windows and reboots the computer
(in both computers) to caldera dos. I've done a bit of research and
have seen some fixes that entail altering a file on the floppy rescue
disks, but I never use those disks and was wondering if someone knew
what was happening here, and has an alternate fix. Actually any help
would be greatly appreciated.

Its always been a real problem with DI, that big variation in the thruput.

Try the /IDE=yes command line switch on the
slow PC, that can make a hell of a difference.

Make sure that DMA is enabled on both systems.

I'd try the floppy approach just to see if it fixes the problem.
It isnt hard to edit the virtual floppy so that it works with the
way you use it if it does fix the problem, its just easier to
test using the floppys because its easier to edit the command
line to add that /IDE=yes switch to see if it helps.

Woooooooooooooooooooooohooooooooooooooooooooooooooooo

1259mb per minute ......!!!! ;-)

Thanks for pushing me to try that Rod !!!

Now is there anyway to make that adjustment on the windows version ?
So when it reboots from windows to run, it does the same thing.

Thanks again.

Yeah, just edit the virtual floppy. The manual spells out how to
do that pretty clearly. You're really just editing that command
line in that virtual floppy in exactly the same way you did it with
a real floppy. You just have to open the virtual floppy to do that.

It doesn't work. Something resets the line on reboot. It just goes
back to the orignal command line minus my change ;-(

Then you arent editing the virtual floppy properly. You sure
you're actually saving the changes you make to the virtual floppy ?

Try editing the virtual floppy to add that command switch.
Reboot and check the virtual floppy again. Bet you find that
you didnt actually save the change you made to the virtual floppy.

I've just edited both files with DI5.01 & done an image. On My Asus
A7V266-E/XP1800+/512MB DDR, throughput has doubled to 699MB/min. Next
time Task Scheduler runs Quick Image, I'll check the throughput there as
well. So thanks for the tip Rod. This increase doesn't surprise me too
much 'cos my brother noted a 3 fold increase after changing his m/b
(without that switch).

Forgot to say that the PowerQuest site is so bad
that I usually use google to find appropriate stuff
on it. There's quite a bit of quite good documentation
there, just too hard to find except by using google.

The site 'designers' should be taken out the back and shot.

Yeah, that problem has been around with DI for years now.

Bit of an inditement that they havent fixed it really.

What exactly does this switch do? I was unable to find anything about

No probs, thats what these technical groups are all about.

Basically tells DI about how the hard drive can be used.
The basic stuff like UDMA4 etc reported elsewhere.

Yeah, I cant find anything either, even when using google.
google isnt that great when looking for something like that tho.

Its a switch that powerquest can suggest
if you complain about lousy thruput.

I meant /ide=yes

That obviously works.

Likely /ide=on does too, havent tried it.

Looks like /ide=on is the best to use, and that does
turn up powerquest documentation using google.

And http://www.powerquest.com/support/primus/id1709.cfm says

/IDE=ON
--------------
This switch tells the PowerQuest software
to use IDE instead of DMA transmission.

Try setting this switch to ON. (The default setting
for this switch is OFF (i.e., DMA transmission).)

Presumably they actually mean PIO, not IDE.

I'm a bit mystified with the naming as well. I would have thought DMA
mode would be faster than PIO & IDE. A minor point compared to the
doubling of throughput though.

Hi Rod. I'd like to try this on the real floppy to start with, but
where/how do I put this /IDE=yes switch? I have an XP1700+ (running at
1750) 512RAM and my throughput is about 195mb/m on 2 7200 drives UDMA4.
Does the switch go into the config.sys or what, and which floppy?
Thanks for your trouble.

Exit from Drive Image once it's runnning from the floppy, and then
type PQDI /IDE=ON. Or edit AUTOEXEC.BAT on the second floppy and add
/IDE=ON to the command line that starts PQDI.

That's OK, though I'm not Rod ;)
You edit the autoexec.bat file on disc 2. Just add a space then /IDE=yes
to the PQDI line at the bottom. (or /ide=on):
PQDI /ide=yes.

Yeah, I had the same reaction. Maybe its more complicated than that
when its the only app running and you want max thruput or something.

I was gunna do a bit more research on that yesterday
but got sidetracked on something else instead. May
get around to that today. Currently just going thru
whats accumulated in usenet overnight.

Rod Speed prematurely pulled the chain & typed:

Adding the longer set of switches to the 2nd VFD file has speeded up
scheduled imaging as well, though interesting not by so much. Perhaps
this ain't the case 'cos running from QuickImage reboots before any
average thruput is displayed & always seems to be more than the
real-time counter would suggest.

I'm yet to try restore to see if that speeds up as well. My brother
commented that PQ maybe reluctant to mention this switch 'cos it might
be less reliable. My max figure of 699MB/min is with all options off &
high compression (no slower than med comp) with the image being stored
on the same disc. I'll check the QuickImage to my 2nd drive but I don't
expect anything startling 'cos the speed was the same before adding the
switches writing to either.

I hope the =yes works, I've used =on!

Yeah, the powerquest documentation is pretty poor
on that switch but it looks like its IDE specific, basically
controlling the mode used with an IDE interface.

You'll find some similar comments in groups.google seaching on
the /IDE=on string. That what I started to look at yestereday.

It also has different effects with image creation
and restoration which isnt very surprising.

Yeah, thats the other variable, whats displayed
and real thruput measured separately with a
stopwatch and the total data volume.

There are some comments on the cdrom
drive disappearing if that is used etc.

I guess it could be less reliable in a data corruption
sense because the UDMA modes do have CRCs and
PIO modes dont, on the IDE physical layer protocol.

Yeah, not surprising that it varys with the physical
drive when its basically specifying the IDE mode to use
at the physical layer protocol level and drives vary there.

> I hope the =yes works, I've used =on!

I've not seen any evidence that it matters except when
searching using google. I bet its just testing for both
when its parsing the command line switches at run time.

No speed increase here with or without the switch and using either
=yes or =on ... but I'm doing high compression so maybe the cpu
crunching is the bottleneck ... getting around 700-750MB/min to a 2nd
drive ... 2.0GHz P4, 256MB RAM, 7200rpm drives

I don't use DI without compression so can't comment. ~700MB/min is what
mine has increased to! Someone I know was running with an Asus A7V333.
they changed some setting which is now forgotten & got a 3 fold increase
in performance. Some PCs seem to run DI at max speed anyway.
