Message-ID: <kientzleDuB4x3.IHt@netcom.com> Organization: NETCOM On-line Communication Services (408 261-4700 guest) Date: Wed, 10 Jul 1996 03:12:39 GMT Lines: 32 Sender: kientzle@netcom21.netcom.com I'm trying to add a SCSI disk to my system, and ran into a perplexing problem. I've just installed an NCR 53C825 SCSI controller. The controller worked great under FreeBSD 2.1R, but the old surplus Seagate I was using with it sounded like a jet engine. (I had no problems partitioning, formatting, etc, the Seagate drive.) I'm trying to replace the Seagate with a new (much quieter) HP drive. The HP drive works just fine under DOS; at least I could partition, format, and copy files onto it with no problems. Under FreeBSD 2.1R, all is not so rosy. It probes just fine: > ncr0 <ncr 53c825 wide scsi> rev 2 int a irq 9 on pci0:18 > (ncr0:0:0): "HP C3725S 6039" type 0 fixed SCSI 2 > sd0(ncr0:0:0): Direct-Access > sd0(ncr0:0:0): FAST SCSI-2 100ns (10 Mb/sec) offset 8. > 2047MB (4194058 512 byte sectors) However, when I try to run `fdisk sd0' from FreeBSD, it fails claiming an I/O error or `device not configured', and the following perplexing message is dropped into the log file: > sd0(ncr0:0:0): ABORTED COMMAND asc:4e,0 Overlapped commands attempted Usually this is repeated several times. Any attempt to manipulate this drive (scsi, fdisk, disklabel, dd, etc.) meets a similar failure. Any clues? I'm going to start phoning mail-order companies to see if I can find a good 1.5-2gig drive within my price range, but if all else fails, I guess I'll break down and add another IDE drive. <sigh> - Tim Kientzle
