I am writing this mailing list in a desperate attempt to find out how to restore my hdd with out loosing all the data on it. Recently I added two additional hard drives to my freebsd 4.2 system. Once I booted up my system and dl'ed some things with wget a bunch of errors occurred resulting in "kernel panic" and then system halt. When I rebooted I get and error and cannot boot freebsd error: Verifying DMI Pool Data ......... | int=00000000 err=00000000 efl=00010246 eip=00001b2c eax=00000002 ebx=00000002 ecx=00006564 edx=00000000 esi=00094cdc edi=000022bf ebp=00094cbc esp=00094ca4 cs=002b ds=0033 es=0033 fs=0033 gs=0033 gs=0033 ss=0033 cs:eip=f7 35 98 24 00 00 89 c7-89 f9 0f af 0d 9c 24 00 ss:esp=00 00 00 00 e0 4c 09 00-dc 4c 09 00 bf 22 00 00 BTX halted to try to fix this problem I installed a minimal install of fbsd on another hdd and ran fsck /dev/ad1a which said this: ** /dev/ad1a BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE /dev/ad1a: INCOMPLETE LABEL: type 4.2BSD fsize 0, frag 0, cpg 0, size 9809920 Although it doesn't really help I can still df -h it; df /dev/ad1a prints: Filesystem Size Used Avail Capacity Mounted on /dev/ad1a 4.5G 1.5G 2.7G 36% fdisk /dev/ad1a prints: *****Working on device /dev/ad1a ********* parameters extracted from in-core disklabel are: cylinders=621 heads=255 sectors/track=63 (16065 blks/cyl) parameters to be used for BIOS calclations are: cylinders=621 heads=255 sectors/track=63 (16065 blks/cyl) Media sector size is 512 Warning: BIOS sector numbering starts with sector 1 Information from DOS bootblock is: The data for partition 1 is: <UNUSED> The data for partition 2 is: <UNUSED> The data for partition 3 is: <UNUSED> The data for partition 4 is: sysid 165,(FreeBSD/NetBSD/386BSD) start 0, size 50000 (24 meg), flag 80 (active) beg: cyl 0/ head 0/ sector 1; end:cyl 1023/ head 255/ sector 63 Is the data on my hdd completely unrecoverable?
