1542A People,
Thanks for responding :-)

I am enclosing my testblock program while I'm on line,
I'll answer you individually later,
I suggest those of you that would have to rebuild machines out of old cards,
might want to hold fire for now, & let those that have machines currently
running do a first test (to save you time).

Since my posting,
I have written & read a 190 meg image on sd3 using a system with a 1542B,
then I took it to the 1542A system, as sd1 ... it blew within a few K.

Someone asked about 1542 CF ... well they're newer than my 1542B,
which is also OK, so I guess one would not expect this problem there :-)

The test on a 1542A system is simple:
	make
	./testblock -v -l 10000000 /usr2/tmp/rubbish
(where /usr2/tmp must be on /dev/sd1 or 2 or 3, but not /dev/sd0 or /dev/wd*
& wait to see if you get something like:
	data mismatch at byte 40961 (0xa001), after 0 (0x0) previously checked ok.

begin 644 testblock.tgz
end
