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 -------- Julian -- Julian H.
