On boot I see the following on an IBM T30 laptop: Mounting root from ufs:/dev/ad0s1a WARNING: / was not properly dismounted ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 ad0: FAILURE - READ_MUL status=59<READY,DSC,DRQ,ERROR> error=40<UNCORRECTABLE> LBA=376639 panic: vrele: negative ref cnt syncing disks, buffers remaining... 9 9 9 9 9 9 9 9 9 9 \giving up on 9 buffers. And the same occurs on every reboot and the machine isn't usable anymore. I'd like to salvage the data that's in the hard disk. Any ideas on how ro recover data from the hard disk? The disk is only 4 months old. Thanks, Alan Evans
