Hello, I have a HP SureStore 5000 SCSI DAT drive on an Adaptec 2940 SCSI controller in a Pentium P166 system with an Intel motherboard. I sometimes need to transfer data from a SUN running 4.1.3U1 with a HP C1533A drive (aka Surestore 6000). I can write a 90m tape on the SUN, but when I try to read it on the PC it will read some of it and then start resetting the SCSI bus and eventually the whole process will hang and have to be killed. It always happens at the same place on the tape. The same tape will produce the same results on another system with a HP35480 drive (aka Surestore 4000 I think) running 2.1.5-RELEASE. The tape can be read back correctly on the SUN. My suspicions are that there is a problem reading long files from the tape as the file that I was having problems with was netscape at 5MB. The tape was written using tar. The error messages are reproduced here: Nov 11 20:53:28 tompc /kernel: ahc0: target 4, lun 0 (st0) timed out Nov 11 20:53:30 tompc /kernel: ahc0: target 4, lun 0 (st0) timed out Nov 11 20:53:30 tompc /kernel: st0(ahc0:4:0): UNIT ATTENTION asc:28,0 Nov 11 20:53:30 tompc /kernel: st0(ahc0:4:0): Not ready to ready transition, medium may have changed Nov 11 20:53:30 tompc /kernel: sd0(ahc0:0:0): UNIT ATTENTION info?:4020040 asc:29,0 Nov 11 20:53:30 tompc /kernel: sd0(ahc0:0:0): Power on, reset, or bus device reset occurred Nov 11 20:53:30 tompc /kernel: , retries:4 Any ideas would be welcomed. -- Tom. ---------------------------------------------------------------------------- Tom Crummey, EMAIL: tom@uces.bangor.ac.uk | /\ University of Wales, Bangor, | / \/\ Unit for Coastal and Estuarine Studies, | /\/ \ \ Ynys Faelog, Menai Bridge, TEL: +44 (0)1248 713808 |/ ======\=\ Gwynedd, LL59 5EY, U.K. FAX: +44 (0)1248 716729 | B A N G O R ----------------------------------------------------------------------------
