Hi, I have a little more information on the problem. Well, it doesn't appear to be a clear-cut problem with the drive. I took out the 3940UW and merged the two SCSI chains onto one and put them on a 2940UW. Then everything worked fine. I then yanked out the 2940 and put the 3940 back in (but all on one channel) and everything works fine there too. One thing I did notice. When I booted verbose with the devices split, Channel A didn't detect Autoterm correctly. It thought there were no devices connected: ahc0: <Adaptec 3940 Ultra SCSI host adapter rev 0x00 int a irq 16 on pci2.4.0 ahc0: Reading SEEPROM...done. internal50 cable not present internal68 cable not present brdctl == 0xec external cable not present eprom is present brdctl == 0xec low byte termination enabled, high byte termination enabled ahc0: aic7880 Wide Channel A, SCSI Id=7, 16/255 SCBs Resetting Channel A ahc0: Downloading Sequencer Program...ahc0: 421 instructions downloaded Done ahc0: Probing channel A Choosing drivers for scbus configured at 0 scbus0 at ahc0 bus 0 ahc0: target 0 using 16Bit transfers ahc0: target 0 synchronous at 20.0MHz, offset = 0x8 sd is configured at 0 sd0 at scbus0 target 0 lun 0 sd0: <MICROP 4345WS x43h> type 0 fixed SCSI 2 sd0: Direct-Access 4340MB (8890029 512 byte sectors) sd0: with 4811 cyls, 11 heads, and an avera When I put everything on Channel A, it detected termination correctly and seemed to be working fine. I should mention that forcing the termiantion setting made no difference as far as the system working. -- Keith Mitchell Head Administrator: acm.vt.edu Email: kmitch@weenix.guru.org PGP key available upon request http://weenix.guru.org/~kmitch Address and URL (c) 1997 Keith Mitchell - All Rights Reserved Unauthorized use or duplication prohibited
