Timing issue?

[starf81]

Hello!

My main Amiga setup is an A1200 Rev.2B motherboard (not fixed) with a Blizzard 1260. Sometimes it crashes and reboots without any reasons. I think it can be the famous "timing issue" but... can I have a confirm? I mean, what are syntomps to identify the timing issue that affects Rev.1D4 and 2B (particular error codes or behaviours)?

Thanks in advance!
Alex

mine a1200 rev2b with bliz1260, never crash without a software issue. after 12 years of work (10 with 060 on) and varius configs of os, ram, hard disk and other extra hardware, i can be absolutly on this.

-edit-
cordiali saluti alla citta' eterna :-)

Thanks for your reply.

I'm afraid of that it could be a software issue since it happens just using the OS3.9. If I boot from a floppy disk, the A1200 is stable.

I don't know what is the cause, do you think I'd format and re-install the OS?

Thanks and... TANTI SALUTI ANCHE A TE!!!  :-D

I also had this problem when I use my 2 GB harddisk.

When you installing OS 3.9 you get a question about 4-way IDE adapter. Select this. After the installation you change the Maxfiletransfer in HDtoolbox to fffe0.

My problem also disappear when I use a Hitachi/IBM or Toshiba notebook HD. I only had problems with a Fujitsu HD.

Yes, I did it...

Well... I've just tried but it doesn't accept the new value.
By default, it is set as 0x0001FE00. I've changed and saved the new value but it shows always the default one.
Could you help me? It's the first time I do something like this... :-)

Yes, also my HD is Fujitsu... :-(

Thanks!

What happend without changing the Maxtransfer?

Does it run without crashes?

[starf81]

It crashes specially surfing into the HD, opening programs and/or moving files. Sometimes it shows errors for DH0.

So I think that your idea is right to solve the my issue... any idea to change that value?

[amiga1260]

Try this 0x0000FFFF or 0x0000FE00. This should work. Don't forget to change every partition.

Here is a manual about HDtoolbox:

A good tip here is if you are using your Amiga for web browsing, set aside a separate small partition exclusively for the Internet Web Pages Cache

Then if your Amiga crashes whilst surfing the Web, any checksum errors / validation issues will only be contained on the InternetCache: parition and wont affect important data on other partitions.

Your Amiga should also be faster at surfing webpages as this smaller hard cache partition wont suffer from fragmentation issues.

Are you confident the hard disk doesn't have any bad blocks/integrity problems and the 2.5" IDE cable is good quality.

another solution, if your problem has to do with hard disk, is to install sfs to the rdb and format the partitions with it. i mean, maybe it's an ffs problem...
