Help : Can't open /dev/rdsk/c0t0d0s7

Question

Hello,
I have a Sun Blade 150, with SunOS 5.8.
And I had a problem with my disk, and now when I reboot it says:
/dev/dsk/c0t0d0s1: I/O error
The system is coming up. Please wait.
checking ufs filesystems
/dev/rdsk/c0t0d0s7: I/O error
Can't open /dev/rdsk/c0t0d0s7
/dev/rdsk/c0t0d0s7: CAN'T CHECK FILE SYSTEM.
/dev/rdsk/c0t0d0s7: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
WARNING - Unable to repair one or more filesystems.
Run fsck manually (fsck filesystem...).
Exit the shell when done to continue the boot process.
When I run FSCK I checks /dev/rdsk/c0t0d0s0 OK, and then say's Can't open /dev/rdsk/c0t0d0s7.
I don't have any backup of this, is there a way to fix this?
Thanks,
JS

Hello,
It first happened this: http://forum.java.sun.com/post!reply.jspa?messageID=9460392
Then I use the SunOS install CD to use format to get the label backup, and now the system boots-up, and shows that errors.
Its only missing the SWAP (c0t0d0s1 and c0t0d0s7).
/etc/tab:

/dev/dsk/c0t0d0s1 - - swap - no -

/dev/dsk/c0t0d0s7 /dev/rdsk/c0t0d0s7 /export/home ufs 2 yes logging
swap - /tmp tmpfs - yes -
