Need help in scripting to do repair in format tool of Solaris

Hi,

I posted my problem in Solaris forum, but I think, I am expecting a script, which should solve my purpose. I am not a scripting person, so need help here.

I am on Solaris 10, in failsafe mode. Manually I run format command and it takes me to options, I pick "repair" and enter, it waits for my input at "Enter absolute block number of defect:", here I need to give block number, which is 39594646. It asks for confirmation, I say Y and enter. It will take some time to repair and came back on "repair" prompt. I need to repeat same for block 39594646 to 585912500 so manual repairing is not possible. I need to say n also, if block is not defective.

Can somebody help me with this kind of script ?
Code:
# format c0t0d0
selecting c0t0d0
[disk formatted]


FORMAT MENU:
        disk       - select a disk
        type       - select (define) a disk type
        partition  - select (define) a partition table
        current    - describe the current disk
        format     - format and analyze the disk
        repair     - repair a defective sector
        label      - write label to the disk
        analyze    - surface analysis
        defect     - defect list management
        backup     - search for backup labels
        verify     - read and display labels
        save       - save new disk/partition definitions
        inquiry    - show vendor, product and revision
        volname    - set 8-character volume name
        !<cmd>     - execute <cmd>, then return
        quit
format>
format> repair
Enter absolute block number of defect: 39594665
Ready to repair defect, continue? y
Repairing hard error on block 39594665 (3167/11/290)...ok.

format> repair
Enter absolute block number of defect: 39594666
This block doesn't appear to be bad.  Repair it anyway? n
format>

NAME
addbadsec - map out defective disk blocks SYNOPSIS
addbadsec [-p] [ -a blkno [blkno...]] [-f filename] raw_device DESCRIPTION
addbadsec is used by the system administrator to map out bad disk blocks. Normally, these blocks are identified during surface analysis, but occasionally the disk subsystem reports unrecoverable data errors indicating a bad block. A block number reported in this way can be fed directly into addbadsec, and the block will be remapped. addbadsec will first attempt hardware remapping. This is supported on SCSI drives and takes place at the disk hardware level. If the target is an IDE drive, then software remapping is used. In order for software remapping to succeed, the partition must contain an alternate slice and there must be room in this slice to perform the mapping. It should be understood that bad blocks lead to data loss. Remapping a defective block does not repair a damaged file. If a bad block occurs to a disk-resident file system structure such as a superblock, the entire slice might have to be recovered from a backup. OPTIONS
The following options are supported: -a Adds the specified blocks to the hardware or software map. If more than one block number is specified, the entire list should be quoted and block numbers should be separated by white space. -f Adds the specified blocks to the hardware or software map. The bad blocks are listed, one per line, in the specified file. -p Causes addbadsec to print the current software map. The output shows the defective block and the assigned alternate. This option cannot be used to print the hardware map. OPERANDS
The following operand is supported: raw_device The address of the disk drive (see FILES). FILES
The raw device should be /dev/rdsk/c?[t?]d?p0. See disks(1M) for an explanation of SCSI and IDE device naming conventions. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Architecture |x86 | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ SEE ALSO
disks(1M), diskscan(1M), fdisk(1M), fmthard(1M), format(1M), attributes(5) NOTES
The format(1M) utility is available to format, label, analyze, and repair SCSI disks. This utility is included with the addbadsec, diskscan(1M), fdisk(1M), and fmthard(1M) commands available for x86. To format an IDE disk, use the DOS "format" utility; however, to label, analyze, or repair IDE disks on x86 systems, use the Solaris format(1M) utility. SunOS 5.10 24 Feb 1998 addbadsec(1M)
