recovery partition table from fdisk?

I have two disks on a sun blade 100. I just installed a solaris8 on the first disk. The installation was successful. But the problem is now I lost all data / partition on my second hard disk.

The possible reason could be:
1. I used default web start install. During the installation I didn't select the disk2. so I am not sure if solaris 8 will automatically erase the whole partition table on all disks in the system.
2. I did something like:
fdisk /dev/rdsk/c0t2d0s0 (the 2nd disk)
and answered 'yes' when it asked "type 'y' to accept the default partition. otherwise type 'n' to edit the partition table.

Now I guess 2 has caused the problem. and might have wiped out the partition table on the 2nd disk. Is there any way to recover it back? cuz the data are very important. I am a beginner in solaris. please offer your generous help here.

Thanks,
motor98

NAME
repartition - load a partition table SYNOPSIS
repartition device [partition-file] DESCRIPTION
Repartition uploads a new partition table for the partitions of device. The table is obtained from the first sector of partition-file if given, device otherwise. Device may refer to the whole drive or a primary partition, depending on whether you want to upload a partition or a subpartition table. The partitions will be truncated to fit within the enclosing device like the disk driver does, unless the numbers are coming from partition-file. EXAMPLES
repartition /dev/hd0 repartition /dev/hd4 /etc/hd4.table Reload the partition table of drive 0 setting /dev/hd[1-4], and the subpartition table of /dev/hd4 setting /dev/hd4[a-d] using a file. The latter may be useful if you need more than the 4 subpartitions a single Minix partition gives you. DIAGNOSTICS
The new table is printed on standard output. FILES
/dev/hd[0-9] SEE ALSO
hd(4), part(8). BUGS
The disk must be in use for the changes to stick. The partition table of an idle disk will be reloaded on the first open. AUTHOR
