I ran fdisk
#fdisk /dev/rdsk/c0d0p0

here is the output of it
             Total disk size is 9729 cylinders
             Cylinder size is 16065 (512 byte) blocks
    Partition   Status    Type      Start   End   Length    %
    =========   ======    ========  =====   ===   ======   ===
	    1                 EXT LBA     1     329   329       3  
  1. Create a partition
  2. Specify the active partition
  3. Delete a partition
  4. Change between Solaris and Solaris2 Partition IDs
  5. Exit (update disk configuration and exit)
  6. Cancel (exit without updating disk configuration)
Enter Selection: 6



I believe the disk is healthy , if you have any further checks please give it to me

this is bad news... i don't know if you can rescue your solaris installation... if the fdisk information is missing, solaris can't work with the disk. so i hope you have a backup of your data!

No i don't have any backups at all , is there any way to recover the data

so this is really bad news... i don't know if you can create the fdisk partition new and access the data which should be still on the disk. i've never done something like that before. maybe one of the other guys has ideas about that.
if not, your data is lost and you need a new installation and maybe a new disk because the old might be the bad part in this...

Thanks for your efforts
i don't care for the disk the data is the most precious i'm looking for any suggestions from the guys out there

i tried to dd c0d0p0 and c0d0p1
#dd if=/dev/rdsk/c0d0p0 of=/dev/null bs=1024k
^C11553+0 records in
11553+0 records out

slices 2,3,4,5,6,7, don't work

There was some hope for you to recover your data before but I'm afraid you somewhat compromise them with such a questionable command.
You overwrote the first partition by the full disk first 11 MB.
Achenle suggested you to output the dd command to /dev/null. That was to check if the disk was readable. He never suggested to output anything to the disk itself, which is something you should never do when trying to recover data.

In my opinion your best bet now is a data recovery service. As you probably know data recovery can be very expensive. jilliagre, your math is off, 11553 records * 1024k = 11GB rather than 11MB.

Its too bad you have to learn the hard way how important backups are. Having important data with no backup is like owning a home with no insurance. You will rarely file an insurance claim, but you don't want to be the person whose house burned and has no insurance.
