The 40 mb hard disk has three partitions, with the first one assigned to DOS, the second for /usr and the third one for root. Last night, I tried to move Minix to a new 25-Mhz 386 system, with a 80 MB harddisk. From floppies, Minix (protected mode) runs fine. But when I try to do a mkfs /dev/hd2 30000 (for example) it immediately craps out with a message something like: put_block failed input line was line 1 Experimenting, I can do mkfs /dev/hd2 n, where "n" is a much smaller number. For example, mkfs /dev/hd2 1000 works fine. So it would appear that I'm running up against a number that is too large for someone (write? ) to handle. Anyone have any experience with this? I don't mind spending some time looking for the problem, but if someone else has already solved it, I sure would appreciate knowing about it. BTW, the disk is 9 heads, 1023 cylinders, 17 sectors per track, 512 bytes per sector. at_wini appears to work fine with it, using andy's suggested test of dd if=/dev/hd0 of=/dev/null count=1000. ====================================================================== John Nall Internet: nall@nu.cs.fsu.edu Computer Science Department Florida State University "Today, a Moon Moth -- tomorrow, a Sea Dragon Conquerer!!"
