fine for me.

Yesterday a major desaster happened: I stumbled across the power cable of my Dell Inspiron notebook. The notebook fell to the floor. FreeBSD was running at that time. Nothing seemed to got damaged, just a palm rest popped off.
Ah yes, the HD bay sprung off and in a moment of reflex I pushed it in again in the running system. After that I tried to mount the disk (which had not been mounted at that point of time). Anyway, trying to

SEARCH FOR ALTERNATE SUPER-BLOCK FAILED. YOU MUST USE THE

SUPER-BLOCK TO SUPPLY NEEDED INFORMATION; SEE fsck(8).

Any idea what I can do now?
I wrote a little program that opens /dev/ad2s1e
#include <stdio.h> #include <sys/param.h> #include <sys/stat.h> #include <sys/file.h> #include <sys/time.h> #include <sys/mount.h> #include <sys/resource.h> #include <sys/sysctl.h> #include <sys/disklabel.h>
#include <ufs/ufs/dinode.h>
#include <ufs/ufs/ufsmount.h>
#include <ufs/ffs/fs.h>
#include <fcntl.h> #include <ufs/ffs/fs.h> main(){ int fd; int k,i=0; int buf[512/(sizeof (int))]; if((fd=open("/dev/ad2s1e",O_RDONLY)) < 0) printf("error opening device\n"),exit(2); printf("opened device\n"); while(read(fd,buf,512)>0){ for(k=0;k<(512/(sizeof (int)));k++){ /*if(buf[k]==FS_UFS1_MAGIC) printf("UFS1 * %d\n",i),fflush(stdout); */ if(buf[k]==FS_UFS2_MAGIC) printf("UFS2 * %d\n",i),fflush(stdout); i++; } } }
I'm not sure whether my approach is correct. Anyway, the blocks I find with that method
aren't recognized as superblocks either.
