Under 4.7-R and 5.1-R, I've found a file that won't copy to a floppy. In exploring a memory test available at: There are two distributions in question: 'Linux Memtest86 v3.0 Source and binary Package' 'Linux Memtest86 v2.9 Source and binary Package' Each of these distributions comes with a precompiled disk image called 'precomp.bin': % ls -ln memtest86-*/precomp.bin -rw------- 1 1001 1001 84480 Feb 28 2002 memtest86-2.9/precomp.bin -rwx--x--x 1 1001 1001 84420 May 21 2002 memtest86-3.0/precomp.bin When copying these to a floppy as root (using two different machines, and several floppes for testing:) # dd bs=8192 of=/dev/fd0 if=memtest86-2.9/precomp.bin 10+1 records in 10+1 records out 84480 bytes transferred in 3.775199 secs (22378 bytes/sec) # dd bs=8192 of=/dev/fd0 if=memtest86-3.0/precomp.bin dd: /dev/fd0: Invalid argument 10+1 records in 10+0 records out 81920 bytes transferred in 3.731600 secs (21953 bytes/sec) Got any quick clues, or should I just file a PR now?
