@Doommaster

So what ?

I have bought about 15 HDs fror my Amigas in the past year (all from PC-people/shops),
and I only ever once used a low-level-format ....

..... and that was connecting an old 20mb MFM HD to an A2000 via the c't-OMTI-adaptor
and an Seagate ST11-controller (suitable for IBM-XT).
That was done using an
enourmos Amiga-Basic program,  but in the end I decided to get an 2088 and
to mount the HD via Janus .... :-o

But :
I never lowlevel-formated the SCSI-HD I had in the A2000 or A4000.

I never low-level-formated the IDE-HDs I had i^n the A2000,A1200,A400 nor the
once used for Amithlon or  now in the Pegasos.

To the orginal poster:
It seems that you had set the BOOT-PRI too high as the new HD seemed to be
regognized at 1st try (maybe not with full capacity).

Make sure that your WB-partition on the Quantum has the highest BOOT-PRI
(set in the HD_setup-utility) and it should boot.

6. Deny that you have ever announced it
7. Blame someone else

BEEEEEEEEP WRONG  :-P  :-o

Amiga-floppy-drives are fixed speed and just the same as the PC-ones on the
HW side (apart from the little flip-flop needed by external ones), I even once had
a drive from an Atari-ST connected to my A500  :oops:

The Amiga-HW just writes a shorter sync-gap, and thats whats keeping an PC
from reading Amiga-formated floppies.

Nope .....

Amiga-DD-floppies spin just like PC-ones (Ior how do you think my experment with the
Atari-floppy worked). Amiga-HD-floppies do spin at half the speed of PC-ones as
Paula isn't capable of doing the double amount of data it would get otherwise.

But this reduced speed is used throughout the whole disk, while the old
800k Mac-floppies used different speed for differnet cylinders. Mac-HD-floppies are
again HW-compatible to those used in PCs.

The floppy-controller in a PC has a fixed lenght for the sync-gap in it's HW (3bytes AFAIR),
while the Amiga uses only 2.
