I tried to do some searching, but only found some stuff in questions indicating a number of people seeing the same thing, but only one person suggesting anything and that didn't produce any different response. The error message still came up. Several posters sseem to report hangs while reading the CD during an install when the error appears. I burned a 7.1 i386 ISO and booted it to do an install, intending to wipe previous stuff and do a clean install. During the boot, I get acd0 FAILURE - READ_BIG MEDIUM ERROR asc=0x11 ascq=0x05 The message is repeated a couple of lines later with different numbers on the asc= and ascq= Someone suggested ignoring it. One responder suggested doing: 'enter the bootloader prompt (6) & type set hw.ata.atapi_dma=0 boot I have tried this, but gotten the same error messages. I am reluctant to wipe stuff and start trying to write new stuff if things are going to fail in the middle even though I have backups. I depend on this system for a lot of communication. Has this been reported - and I just haven't been effective on my search? Is there some resolution or work around that works? Thank you for any help you can give, ////jerry
