Okay, here's the story,,,
Bought a Amiga 1200 and everything appearred to work great. Had a CF instead of a hard drive. It was loaded with almost every games and utilities imaginable.
Well, things started turning sour when I couldn't format or prep another CF in the PCMCIA bay. Tried different cards and card readers but no go. It will read/write
CF's that are formatted on another A1200 I have. Thinking that this was a OS/install related problem I decided to make the machine new again, yeah right.
I removed the CF card and installed a 10Gig IBM TravelStar 2.5 HD. I then went about the process of doing the Partitioning/Install and updating. I tried to make 2
partitions, one WB and other DATA. Couldn't keep the partitions solid as on a reboot I get, "Not a DOS disk"... Tried just one 4gig partition and after a couple
of reboots it loses it's boot process and data. The drive was tested fine on laptop and external drive case. I'm thinking my 3.1 ROMS could be faulty as they don't
appear to be factory(They're hand-written). I have tried it nine ways to Sunday but no go on the PCMCIA CF problem or the new Hard Drive.
Anyone else have a clue as to fixing this Miggy? :confused:
A1200 HD40 with 10GIG IBM drive, 3.1 KS, 3.1 WB disks.
MTEC 1200/40 Accel with 4 gig (had it in and out for installs)

I usually made a system partition about 500megs big then split the rest into 2gig partitions. Thats what most people recommend. I usually didn't use very large harddrive with my miggies though.

Whats your MaxTransfer settings when setting up the CF card or the 10 gig hard drive?
Incorrect MaxTransfer can cause those kind of issues.

Do you have any trapdoor expansion?
The PCMCIA CF problem seems like you have the zorro space of that slot occupied by any non compatible expansion over 4 Mo of FAST RAM.
I believe that the 10GB hard drive partionning problem could be non related to that and caused by bad filesystem (FFS, SFS, ...), scsi.device version, NSDPatch non installed: yu should have a look with Check4GB (on aminet).

Pay attention to above statement and keep boot partition under 2gb.

This is always worth a read SFS guide (http://wiki.abime.net/amigaos_workbench/sfs).
BTW it took me 100 attempts to install OS3.9 properly on my CF HD using WinUAE......oh what a fun few days ;)

It sounds to me he is creating partitions outside the 4gb space and this is causing the problems, either keep all your partitions within the first 4gb of the drive, i.e DH0 500mb, DH1 1.4gb DH2 1.9gb or:
If you want to use the rest of the drive you need to get your head round 'large disk' support.

Well,
I have tried a few things on here but without much luck. The hard drive will not go past the 4 gig limit, with both SFS and IDEFIX onboard. I have tried several installs,
with MTEC 1230/28 installed/and without and have checked my MAXtransfers at 0x1fe00; no good. Can't hook up the drive to a PC (USB) and use WINUAE, keep getting,
Exception Processing Message, c00000a3 Parameters 75b6bf7c 4 75b6bf7c 75b6bf7c, whatever that is. Now I know why 80% of the people like Windows, but I am
not done with this Miggy yet. The CF issue is a pain, out of 4 cards, only 2 show up and are workable. All 4 cards do work in my other NTSC miggy. Couldn't prep or
format them in the bad machine; either getting card write protected/ or can't format cylinder 0. The PCMCIA slot appears to be good , with no bent pins. Where do
I set Maxtransfer for the CF??? I have spent 3 days on this thing and the wife would like her kitchen table back at some point.
Can someone give me a clue as to the order and process to do this step by step?
IE,
1 Use Install disk and partion hard drive 500Meg(DH0),1.6gig(DH1),1.7gig(DH2), set maxtransfer to 0x1fe00, save
2 Reboot and Format Partions
3 Install WB 3.1, completely
4 Install SFS then IDEfix (I can register that one,,,Amiga forever)
5 Load drivers for CF card, format CF
Enjoy Miggy
All help welcomed...
Thanks,

Ideas for troubleshooting, swap drive from working A1200 into the suspected bad A1200. If problems are still there,
motherboard issue. I could swap KS3.1 Roms to see if it's the same as the possible mentioned above. Working A1200
has a 40Gig drive but it's only using 8Gig of partition. How can I tell what drivers(SFS ,IDEFIX) are loaded; is there a
boot file?
I getting ready to buy a PAL motherboard if it doesn't work. Hey, was there a problem with the later revision of
motherboards? I know the 1D4's are the most sought after; will have to check and see what version it is....
Going bonkers on this thing as you can tell by my posts.. ;)
