Try a very short two connector only EIDE cable for the Maxtor alone and see
if UDMA mode works.  If that fixes UDMA mode then get a cable from
www.ultracable.com and reconnect both the Maxtor and Fireball.

Probably running DMA mode 2.

Wintune is useless as a disk benchmark.  Use Winbench98 and HDTach.

Right.

What is the read burst rate and CPU usage reported by HDTach?

Results of HDTach:

MAXTOR : Read burst: 12.6 mbps
                    Random access time 16.7 ms
                    CPU usage: 15.2 %

FIREBALL : : Read burst: 7.4 mbps
                        Random access time 17.1ms
                        CPU usage: 51.4 %

DMA mode 2.

Probably PIO4 or PIO 3.

Try the cabling experiment I previously suggested.

-------------------------------------------------------------------------
Problem solved !

Double cause:

1. The clock frequency should be 66MHz but was set to 75MHz. This prevented
the
Maxtor to use UDMA (this cable was not to long). After resetting the clock
to 66MHz and disabling the secondary controller, it worked fine with both
the BIOS and the DMA-checkbox in WIN98 enabled.

2. The EIDE-cable to the secondary controller was really to long. Rearrange
some
things in the computer let me use a shorter one: no problems anymore.

Nevertheless I will buy the special UDMA-cables, I believe it will be more
reliable.

New results of HDTach for the MAXTOR:
Read burst: 16.6 mbps
Random access time 23.7 ms
CPU usage: 17.1 %


Thanks !

That's still DMA mode 2.  So the problem still isn't solved.  It should be
>=25MB/sec. for UDMA mode.

Hi WIlly,

I have a simular problem. Read this message I sent about a week ago to
ASUS, but still no reply.

--start quote message ---
I just finished a long conversation with the tech support of Maxtor. A
few weeks ago I installed a Seagate MedialistPRO 9.1 GB 7200 rpm
UDMA/33 drive in my ASUS TX97-E system. I have tried both the 1.08
BIOS and latest beta BIOS and still keep having a performance problem.
I installed the drive under Windows 98 with BIOS Harddrive AUTO, mode
AUTO, UDMA Auto. I use the UDMA cable to connect the drive. It is
partitioned in 4 FAT 32 partitions.

Performance with DMA checked ON in Win 98 System settings gives a
performance of about 5.6 MB/s. DMA OFF makes it go up (!!!??) to 6.3.
The same problem is also happening with my new Maxtor 10 GB 7200 rpm
drive, same settings, same performance issue.

The Maxtor tech rep told me that this particular harddisk is the
industrie standard best at this moment and should at least give a
performance of 12 MB/s or more and performance with DMA ON should be
better than with DMA OFF. He told me, as there are no other causes in
my system, it *must* be a driver (win 98) and/or BIOS problem, because
with DMA on the performance decreases in stead of increasing. So it
looks like an incompatibility problem when DMA is turned on. He
suggested me to ask ASUS for a fixed driver or BIOS fix.

HD Tach results with DMA ON(!)

Read speed maximum 14,7 mb/s,  minimum 10,8 MB/s and average 13,2
MB/s. CPU 20,4 %
---end quote of message---

Curious to see if anybody can solve this?

Regards,
Reinier de Groot.

NB. if possible, please reply to my e-mail address.

Hey Ron, I have a long cable on my IBM deskstar UDMA drive, and this is what
I got on HD Tach:

Burst speed = 27.6 Mb/sec
Access time = 13.2 ms
CPU usage  = 4.5%

Do you think switching to the better cable at ultracable.com would give me
even better performance?

I reported that my problem was solved and I believe it is so.

BUT: I REPORTED THE WRONG TESTRESULTS:

I mistaked the value of read burst with the one of Random Access.
The results after solving the problem are:

                Random Access: 16.6 ms  (not 23.7)
                Read Burst: 23.7 mbps   (not16.6)

Thanks for the reactions,

Willy

The read burst is the most important figure regarding your issues??

Try a very short <=12" two connector only EIDE cable or a cable from
www.ultracable.com.   HDTach's read burst rate should be >=25MB/sec.

Nope.  You're optimal now.

Arghhh!  I want more speed! :)  Thanks Ron, I appreciate the help.

Get a Maxtor Plus 2500.

Hi Ron,

Burst mode shows 22 MB/s. CPU load 23%. Is this the performance to be
expected with my Maxtor 2500 UDMA/33 ? Any other suggestions?

Regards,
Reinier.

That's slightly low but probably ok.  Try a very short <=12" two connector
only EIDE cable and see if HDTach's read burst goes up or CPU usage goes
down.  If it improves then stick with the short cable or try a cable from
www.ultracable.com
