A couple of weeks ago I privately bought Minix-ST. Using the manual I
could successfully install it on my Mega 2's 20 Mb Atari SH 204 drive,
in a way that it wasn't depending on floppy disks (MINIX.IMG
+ 1Mb hd3 + 8 Mb hd4). (By the way did you know that if you boot from hard
disk that way you cannot use your floppy disk drives anymore? To be able to
use floppies you have to boot from floppies).
A week ago I bought a Atari Megafile 60 and sold the SH 204. Then my problems
really started.
At my first attempt I successfuly put the contents of the USR, USER,
ACH1, ACK2, SRC1 and SRC2 disks files on /dev/hd3 under /usr.
I could access all files, nothing was wrong. But... suddenly with no apparent
cause minix thought /dev/hd3 an illegal file system and refused to mount it.
I noticed the boot block of the hard disk partition was zeroed by an unknown
cause, so I couldn't access it with any TOS hard disk utility as well.
The only I could think of was to make a backup of my TOS partitions,
reformat the hard disk, restore my TOS partitions, and try to make a minix
filesystem again. When I did that, I got error messages, and minix did'nt
even access the hard disk (the disk activity light didn't come on).
I tried /dev/hd4 instead of hd3 with the same result. Both partitions
can be accessed from TOS, so that rules out hardware errors.
A transcript of my session:
# mkfs /dev/hd4 15695
unrecoverable disk error on device 3/4, block 15694
Error: put_block couldn't write
Line 1 being processed when error detected
Unrecoverable disk error on device 3/4, block (and then came a block number)
- many repeats of above line with each time another block number -
My Megafile 60 consists of 4 partitions, with each 15700 clusters.
Is this a known problem? Has anyone experienced it? If so, is there a fix?
Thanks in advance,
Ryko Prins.

This *really* can't be true. I understand you have /dev/hd1 and /dev/hd2 for TOS and hd3, hd4 for MINIX. But, how do you load the RAM disk, or are you using a patched MINIX version that has its root filesystem on hard disk ?? My situation is this: SH205: (same for SH204) /dev/hd1 TOS 3 Mb /dev/hd2 MINIX 2 Mb / root filesystem /dev/hd3 MINIX 10 Mb /usr usr filesystem /dev/hd4 MINIX 5 Mb /tmp temporaries I don't use RAM disk. It's no problem to access /dev/fd0 and/or /dev/dd0. Don't you forget to mount them ??? Use the right type fd0 / dd0 ???? > I noticed the boot block of the hard disk partition was zeroed by an unknown > cause, so I couldn't access it with any TOS hard disk utility as well. Which is fully correct, compare it to the UNIX filesystem: block 0 - boot block block 1 - superblock etc Since this partition is surely not a boot device, the boot block is unused and therefore zeroed. Check the source of mkfs and you'll see. > The only I could think of was to make a backup of my TOS partitions, > reformat the hard disk, restore my TOS partitions, and try to make a minix > filesystem again.

Both partitions > can be accessed from TOS, so that rules out hardware errors. All special devices in /dev set up correctly ??? Hard disk partitioned correct using TOS utility ??? Correct sizes of partitions ???? Well, that's all I can come up with right now. I've experience with both SH204 and SH205. A colleague of me uses a Megafile 60 partially for MINIX.
