50GB Hard drive size in amiga-fdisk

[Lance Tagliapietra]

Hello,

I'm trying to get a 50GB SCSI hard drive set up on my Amiga system under Debian.  The amiga-fdisk shows
the ~1,000,000 blocks of the drive, but comes up with a logical cylinders value which does not allow me
to use the entire drive space.

Thoughts?

I setup a 73GB drive some time ago using amiga-fdisk from sarge. I'm not
sure, however, if I initialised the RDB with HDToolBox before using fdisk.

If fdisk sets the size of the logical cylinders wrongly for your hard
drive, you can try to edit the number of heads/sectors/cylinders directly
with a hex-editor. The RDB is located in the first 1 or 2 blocks of the
drive.

Hello Rolf,

Thanks for letting me know that this is at least possible.  I believe
I'm using the etch-m68k version of amiga-fdisk:

Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed
|/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad)
||/ Name           Version        Description
+++-==============-==============-============================================
ii  amiga-fdisk    0.04-11        Partition editor for Amiga

I don't recall if I originally partitioned this drive on AmigaDos tools.
I do have a couple AmigaDos partions on it, though, which have mirrors
of my current AmigaDos partitions and I can boot off the drive.

Regards,

--Lance
