HELP!!! Bios Harddrive settings?? Which are better concerning Cyl/Heads/Sec and Transfer?

[coolVariable]

Today I bought a new HD for my Notebook: The IBM 30GB Harddrive IC25N030ATCS04
But now I have "problems" with my Bios:

When I select auto-detect Bios detects different settings for Cylinders/Heads/Sectors than those given by the manufacturer ... which should I use? Which are better?
IBM states the drive has 16383 Cyl / 16 Heads / 63 Sec but my Bios auto-detects something like 17??? Cyl / 15 Heads / 63 Sec ....... ?

I am also puzzled by the Bios Transfer Mode Settings:
For Transfer Mode it auto-detects FPIO4/DMA2 (highest) but for U-DMA transfer mode it only selects U-DMA Mode-2 (and Mode-3 and Mode-4 are available).
Usually higher is better but I was having problems using those two modes ... and in my opinion a new HD (bought today) should support the highest transfer modes, shouldn't it?
IBM states it supports 100MB/sec Ultra DMA Mode-5 as max. transfer rate .... but in my laptop it seeminly doesn't.

what laptop do you have? did you update your bios? sounds like a bios issue.

It's a no name brand laptop ... but it has the newest bios available for it ........

What about the cyl / heads / sec settings? Which is better?

If you go auto-detect, and plug it in and it WORKS, why in the hell would you think about changing it? notebook drives aren't exactly high performance, so you shouldnt be expecting blazing fast speeds anyway. Try both, one will work, one wont. Use the one that works.

But I would like to use my new HD to its fullest potential!
And BOTH cylinder / heads / sector settings WORK but WHICH ONE IS BETTER?
And don't tell me I just should use one f them cause it's working!
Everybody tries to make his/her PC the fastest possible!!!

Screaming at people wont help you here. Calm down.

Telling people to just use a setting regardless if it is good or not in a Computer-Forum isn't helpfull either!!!!

How about keeping to the topic and helping others instead of bossing them around and telling them how to behave?
