About two weeks ago I wrote about the problems with my new Megafile 60.
I can create a file system, but after some time it becomes corrupted:
from about a 100 blocks before the minix boot block to about 250 blocks
after were filled with hex FF's the last time I tried.
Luckily there was not yet data on the previous partition.
Two people gave a helping hand (thanks, guys - at least for trying to help)
and one of them suggested I maybe should look for a patch posted somewhere
at the end of last year which would fix a known problem with large file
systems (mine is 15K).
After two weeks of searching the December archives and the first January
archive I still haven't found the patch.
I don't dare to put Minix again on my hard disk because I am afraid that
next time it will really corrupt data on other partitions.
Therefore, I would like to ask if someone could please post me the patch
that fixes the problem with a hard disk with large partitions?
Thanks in advance,

A friend of mine had problems with a large (32K) partition on his Megafile 60; it wasn't the same problem (his system had problems mounting the partition), but here's the fix; you might want to try it: *** fs/const.h.orig Thu Nov 14 20:35:46 1988 --- fs/const.h Thu Jan 9 20:49:48 1989 *************** *** 1,7 **** /* Tables sizes */ #define NR_ZONE_NUMS 9 /* # zone numbers in an inode */ ! #define NR_BUFS 20 /* # blocks in the buffer cache */ ! #define NR_BUF_HASH 32 /* size of buf hash table; MUST BE POWER OF 2*/ #define NR_FDS 20 /* max file descriptors per process */ #define NR_FILPS 64 /* # slots in filp table */ #define I_MAP_SLOTS 4 /* max # of blocks in the inode bit map */ --- 1,7 ---- /* Tables sizes */ #define NR_ZONE_NUMS 9 /* # zone numbers in an inode */ ! #define NR_BUFS 40 /* # blocks in the buffer cache */ ! #define NR_BUF_HASH 64 /* size of buf hash table; MUST BE POWER OF 2*/ #define NR_FDS 20 /* max file descriptors per process */ #define NR_FILPS 64 /* # slots in filp table */ #define I_MAP_SLOTS 4 /* max # of blocks in the inode bit map */ ------- Eric R.
