Do IBM HDD's have trouble with 112MHZ bus? Your input please....

[Sonoma]

Howdy-

I have a 6.4 GB IBM Deskstar 5 (DHEA-36480) UDMA HDD attached to my Abit BH6
Motherboard. My CPU is a Celeron 266 overclocked to 448 MHZ (4x112 MHZ).
I'm running Windows 98. BIOS is the latest FU revision.

The system is extremely stable and I'm very happy with the performance. I
only have one issue.....I can't enable DMA mode (in the WIN98 Device
Manager). When I have DMA mode enable, the HDD benchmarks significantly
better but when I try to run Norton SpeeDisk (with verify writes enabled) I
get error messages. The message says "Error Verifying Cluster". Once I
turned verify writes off and and ran Speed Disk anyway. Afterward my system
was unbootable!

Any suggestions??

Do IBM Drives just not like the 112 MHZ or what? If you think my drive is
the problem, what drive is recommended for use with the 112 MHZ bus.

I remember that I have seen a note about that 83 MHz (then PCI runs
41.5 MHz which is faster than 112/3=37 MHz) and bus master drivers
with the Deskstar will result in loosing the FAT ! If you overclock to
124x4, you will reach the same limit.

Another 'detuning' step you can take is to lower the PIO rating in CMOS setup
to 3 or even 2. A better strategy would be to buy a Celeron 300A, especially
since the recent drop in price. This will allow the PCI, IDE and AGP devices
to run at spec with the 100 mhz FSB, while still maintaining processor speed
at 450. Cheaper than a new HDD, too. BTW, the IBM Deskstar is a pretty nice
drive.

I have a couple of Deskstars which run fine on my P2 400 clocked to 448 Mhz.
However if I enable DMA in device manager my system files brcome corrupted
resulting in similar symptoms to those originally reported..

Running a Deskstar 8 4.3 gig at 448 (Cel266) with DMA enabled (Win98),
absolutely no problems with either FL or FU (I went back to FL after
ACPI behaviour proved unfriendly).

I have no ISA cards, all PCI/AGP.

Hello,

I have an 8.4gb IBM DHEA drive, basically what you have I guess, but
with more space. I doubt it's your 112Mhz setting that's causing the
trouble, but rather the speed of the PCI bus which the HDs rely on.
On my motherboard, running say 75Mhz bus speed increases PCI bus to
37Mhz, while 112Mhz bus speed increases PCI to 36Mhz. Anyhow, you
probably won't notice anything serious, -until- you defrag your
harddrive!

Don't DO this! I did this by mistake (I left my PC on overnight, and
Win98 defragged it), and my entire HD (that's 8gb, to summarize) got
turned into a real mess. I lost 4gb ;( Luckily, I had backup of most
of it, so no real loss.

I wonder how the future motherboards will deal with older HDs, if the
PCI bus will increase abovethe 33Mhz standard...

You shouldn't have any data corruption on a setting of 75 Mhz (if the hardware
can take it).

My AMD K6-2 266 O/C to 300 (4*75) has been running fine for the last two
months...
(defragging is done every night with Norton SpeedDisk)

Hard drives are quite sensitive, the are quite a bit analog remember.
Any way I got my udma hard drive in 83mhz fsb set at pio3 working fine. I
have only defraged it once because it's 6.4 gig and takes for frigging
ever(Hmmm task scheduler wonder what that does doh!!!!)

Actarus [VL] wrote in message <3642450...@videotron.ca>...

[DeeDe...@yahoo.com]

the problem isn't with the drive but with the IDE interface built into the
motherboard
you have cranked your pci bus up to 56Mhz (1/2 of bus setting on any setting not =
60,66, or 100 and not recommended) and the IDE controller on that motherboard is
actually a built in pci device witch it seems cant handle the truth so set it at
100 and enjoy the speed you can "safely" achieve. It might just be me but everyone
who overclocks seems to not want to accept the facts . When you push a system you
really need to be careful of the signs and warnings it throws you . You shouldn't
try just lowering the performance of one part of your system to gain a very slight
speed increse somewhere else. This whole business of lowering the pio mode of your
hard drive to keep a processor speed up slightly higher than the safe limit is
stupid. Your performance will suffer far more overall by lowering the transfer
rate between your hard drive and cpu than by knocking back the cpu setting one
notch. Enjoy the hard drive I have one myself and would laugh my ass off at anyone
who said to make it go slower so my allready fast cpu could be slightly faster
(have celeron 300a running at 100Mhz = 450 and can assure anyone that if it so
much as hiccups once it goes back to being 300) . Not to scare you as it seems to
be uncommon but had an AMD K-6 233 that I ran at 225 (75 Mhz bus speed) and that
thing burned out but before it did it gave absolutly no indication of failure
until it was allready toast (it started booting me back to the windows desktop
from graphic intensive applications) and then that was that even though the first
time it did it I clocked it back to 233 @ 66Mhz it would continue to eject me from
apps then I went to 166 to check and sure enough same thing then took out every
card and replaced video card with working one from other system and .... same
thing so anyone want to buy an AMD K-6 233 I'll sell it cheap? oh forgot other
check I did before you jump on this great deal my other machine was also an AMD
K-6 233 system so I swapped the cpus and the other machine wouldnt even boot up
while the glitchy one worked great.

just remember bad advice is still just bad or
.....and those are just some of the benifits of an all cheese diet. or

Interesting. I just built two systems with IBM HDDs. One is an 8.4G DHEA, the
other
a 6.4 DTTA. Both seemed to have zero problems at 112 MHz.

I'm running two IBMs (DeskStar 14GXP and 8.4) at 112MHz and have had no
problems (ABIT BX6).

It's interesting to see that people will overclock to 112 MHz bus speed to
gain performance, accpeting that they will not be able to do a defrag on
their drives. I bet that after a couple of weeks, a 112 MHz system with
highly fragmented drives, would be slower than a standard 100 MHz system with
clean defragged drives.

This looks like a load of bollocks to me. I am running a P2 400 at 112Mhz
with no problems whatsoever. I can defrag efficiently and speedily using
Norton 3 I have two IBM Deskstar drives one 10.1 Gb and one 6.4 Gb.

Most IBM hard disk can not support more 100 mhz OC.

I ORIGINATED THIS POST! HERE IS MY RESULT!

I ended up selling my IBM DHEA-36480 on eBay for $167.00 ( I paid $155.00
for it 3 months ago).
Since then I bought a Seagate ST36530A 7200 RPM UDMA drive and I can now use
WIN98 DMA mode with the 112MHZ bus speed. My system ROCKS and so does EBAY!

If you run at 450 (FSB 100MHz) then the drives are not overclocked.
That only happens at non standard FSB speeds (not 66 or 100) when the PCI
bus speed will be above spec.
