Fujitsu ATA66 drives - how to switch them to ATA33

Anyone running ATA66 drives on a PC only able to handle ATA33 may find that the drive is actually running VERY slowly.

IBM has a DOS utility to fix this (IBM.com) and now, so, too do Fujitsu (details below). If you know about other makers having such utilities, please post new messages with details.

I couldn't locate the Fuji program on the main USA site, (or Europe/UK) but did find it easily on the Canadian site: http://www.fujitsu.ca/tech.htm

A bit more info, from the site

UDMA33 Utility (udma333.zip) 9KB in size

The UDMA33 utility is designed to change the status of MPD3xxxAT-UW/AW/EW drives from ATA66 to ATA33. Certain types of BIOS or motherboard, which cannot run a MPD3xxxAT drive at UDMA66, are not defaulting properly to UDMA33 as they should. Users with older systems who experience UDMA4 replies from their BIOS systems during boot up, should use this utility to set their drive to run at UDMA33. The files available here are in Pkzip format. The files should be unZIPed before installation.

Maxtor now has a utility to throttle back their UDMA 4 drives to UDMA 2 at

Thanks Neil! The file to download is called, 66UPDATE.EXE, and is only about 69KB in size.

Here's what the PDF about it says,

Document #: 21006 Rev. 00
Date: 8/26/99 1
Subject: Using the UDMAUPDT.EXE Utility

Summary: To describe potential symptoms that may arise when using UDMA/66 DiamondMax 6800 (and newer)hard drives on older UDMA/33 Motherboards with an older, Award BIOS.

Overview: Some older Ultra DMA 33 motherboards that use the Award (revision date 10/28/98 and older) BIOS have exhibited
compatibility issues with Maxtor DiamondMax 6800 (5,400 RPM), Ultra DMA/66 drives. This symptom has been identified on motherboards (using the Award BIOS) using (but NOT limited to) the following Chipsets:
Intel: 430TX, 440LX, 440BX.
VIA: 586A, 586B, 596, 686.
SiS: 5598, 5591, 5600, 530, 620.
ALi: 1543C, 1533A-J, 1543A1-F.

The symptom manifests itself as a system hang at boot. On some motherboards that use older versions of the Award BIOS, the system
does not properly check the UDMA setting returned by the drive. This results in the motherboard attempting to set itself up in Ultra DMA mode 4 - a mode that it does not support. These issues arise because of a bug in the system's BIOS, NOT a problem with the Maxtor hard drive. Award is aware of this problem and is working on a fix.

To eliminate this problem, Maxtor has developed the UDMAUPDT.EXE utility. This program is designed to change (update) the UDMA Mode that the drive reports to ANY UDMA Mode (0-4). This file can be downloaded from Maxtor’s Website at:
http://www.maxtor.com/library/main.html
It is contained in the file named 66UPDATE.EXE.

NOTE: 66UPDATE.EXE is a self-extracting file containing:
UDMAUPDT.EXE - Utility for Updating Maxtor UDMA/66 hard drives
UDMAUPDT.TXT - this file
Maxtor recommends that you copy 66UPDATE.EXE to a formatted, 3.5-inch floppy diskette. 66UPDATE.EXE must be extracted in
order to execute UDMAUPDT.EXE.

NOTE: This utility should ONLY be used if:
· There is a DiamondMax 6800 (or newer) hard drive physically installed in the system.
· The hard drive is attached to an IDE Interface port on the motherboard.
· The IDE interface that the drive is connected to does not support Ultra DMA 66.
If the interface DOES support Ultra DMA 66 and you are still experiencing problems, please contact Maxtor Technical Assistance.
PROCEDURE FOR USING UDMAUPDT.EXE:
1. Clean boot the system to an A: prompt.
2. Insert the diskette containing the UDMAUPDT.EXE.
3. From the A: prompt, type udmaupdt and press [Enter]. The following will be displayed:

Select Ultra DMA Mode Utility -- Version 1.4
USAGE:
COMMAND LINE INPUTS
/dma: DMA Mode ( 0, 1, 2, 3, 4)
0 - UDMA mode 0 = UDMA 16
1 - UDMA mode 1 = UDMA 25
2 - UDMA mode 2 = UDMA 33
3 - UDMA mode 3 = UDMA 50
4 - UDMA mode 4 = UDMA 66

EXAMPLE COMMAND LINE INPUTS
UDMAUPDT /dma:3

You will be returned to an A: prompt after the following is displayed.

4. From the A: prompt, type in udmaupdt /dma:x (where x is the UDMA mode you want to set the drive to) and press [Enter]. This will execute the UDMAUPDT.EXE program. Maxtor recommends that you select the HIGHEST DMA Mode that your system can
support. For example, if your system could only support DMA Mode 2, you would type:
udmaupdt /dma:2
5. Upon successful completion, the message "Ultra DMA Changed to Mode x in this Maxtor Drive" will be displayed.

That's it

Bob- I notice you filleted the PDF file a tad;

This bit is included--

"NOTE: Contact Maxtor Technical Assistance if you receive the
following message:

"Disk Drive Firmware Needs to be Updated""

Guess whose Hard Drive gave the above message? :-(
I'll post again when Maxtor Tech email me again with a solution.

Thanks Bob

I recently purchased an IBM 22Gb 7200RPM drive and noticed that I couldn't enable DMA in Windows98 control panel. It reported DMA mode 4 (UDMA 66) on boot up.

I downloaded the IBM utility and turned it to DMA mode 2 (UDMA 33), I could then enable DMA.

My read benchmark (as tested with the DV300 Miro expert) went up from 7Mb/sec to 17Mb/sec!!! I knew you would come in useful one day! Thanks again for the tip.

What if you have the original Promise Fastrack and wanted to use Ultra66 drives on it, can you use the software utility still? Thanks.

I've only used an earlier version of the IBM drive utility which would only let you change the drive's settings if the drive was set up as a master connected to the primary IDE channel.

If this is still the case, then it's still no big deal if you have a promise card to remove the promise, fit the drive, make any changes needed in the Bios and to boot from a DOS floppy and run the utility.

Having run it, shut down, pop the Promise back in, undo any changes to the Bios, connect up the drive to the Promise (which, I guess is what you want to do), and restart the PC.

Thanks for the reply. I am not sure however that the work around that you are suggesting will work since the drive will be connected directly to the Fastrack which doubles as my Ultra33 host adapter. Do you know of any Mother board shipping with Ultra66? Thanks.

Further to my post above, Maxtor emailed a firmware update, and I can now use their 66update.exe utility. Excellent prompt response from Maxtor tech support on 2 occasions now.

DJ, are you saying your existing motherboard doesn't have an EIDE connectors?

If it does, and surely, it must do, my suggestion will work - and, since you never boot up Windows, your original Win configuration stays unchanged and, in theory (and, I'm sure, in practise), you should be able to connect up the ATA33'd disk to the Promise card and have it work as though it had never been an ATA66.

As for changing the motherboard - well, there are lots of reasons to do this but, in my opinion, gaining ATA66 support is not one of them. You are very unlikely to see any difference in the drive in ATA33 and ATA66 modes.

There are some ATA66 motherboards out there - but not many - but I can't advise you further, because I don't know details.

Ok I think I get you now. The utility will actually change the drive itself to Ultra33 Mode, and the Fastrack will recognise it as an Ultra33 drive. What I was saying about the mother board was that it not equipped with Ultra33 so for me the Fastrack is not only for raid, but also for me to get Ultra33 performance. In any case I am satisfied that my Fastrack can still be used. Thanks alot for your help.

The version of the IBM utility I used scanned the EIDE bus and displayed all the devices it found i.e both master/slave on both primary/secondary EIDE busses.

As you select each device it tells you if it recognised it, and whether it can be DMA 66 enabled/disabled.

DJ - yup that's what I meant

keithmoore - I'm not at all sure, though, whether the IBM utility (or any other drive utility) would also scan the FastTrak and successfully change the drive, but that, of course, would be the obvious first thing to try.

Quantum have got these AT33/66 swap utitlities, too, and versions for different models of HDD can be downloaded from

http://www.quantum.com/support/csr/software/csr_software.htm

I had to go through an acceptance page, to reach the download page, so if this URL doesn't work, then start higher up,say at http://www.quantum.com/support or even http://www.quantum.com.
