Adaptec sent me new bios's and microcode for 1740 ( I have 10 of them by the way, so it wasn't just one card problem) same problem, tho the new bios did fix some other problems, It did not fix the problem of moving a drive to another scsi controller, without the data being corrupted. Moving from 27/28/29 is fine tho. > > > > -- > Rod Grimes rgrimes@gndrsh.aac.dev.com > Accurate Automation Company Custom computers for FreeBSD >
