i quickly hacked dd to print out the block number of the error instead of the usual message.
kw# /usr/quanstro/5.ddx -conv noerror -if /dev/flash/flash -of /dev/null read: i/o error 0 read: i/o error 4 read: i/o error 8 [etc.] every 4th block errors to block 1532, except blocks 360 376, 896, 1280. also blocks 186368 and 186372 error. also, read errors are inconsistent: kw# dd -if /dev/flash/flash -count 1 -of /dev/null read: i/o error 0+0 records in 0+0 records out kw# dd -if /dev/flash/flash -count 1 -of /dev/null 1+0 records in 1+0 records out - erik
