[Bug 666265] New: Kernel support for Amiga hard disk drive

However, I did make a disk image of the drive using the "dd" command, and successfully mounted that image under Amiga emulation (E-UAE).

From a quick look at your dump, it looks like your partition table may be corrupt.
Do you happen to have a the log from when the physical disk was attached? I expect it to say something about the checksum. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I remember I did try to change the offset, so that the RDSK letters were the first 4 bytes, but it didn't work. (not sure, but IIRC, I did use the "root" option of affs to do that.) Was this useless or did I mess with a wrong value, I don't know. I don't know however how to find the offset of, let's say, the first partition. I first thought too the partition table was corrupted, but it's not the case. Real Amiga filesystem has no trouble with it. UAE has no trouble to recognize the partitions either. I guess that partition table is just less usual and not properly identified by AFFS and the partition table support. I don't have any log from when the disk was installed, sorry. I can't test the physical disk anymore. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm afraid I'm going to have to ask you to pursue this using bugzilla.kernel.org. We definitely don't patch the Amiga partition table code and perhaps one of the maintainers of that code can help you. For now, I'm going to close this as WONTFIX. I just don't have the time to pursue it. If you find a solution with kernel.org, please re-open and we'll incorporate the patch. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
