BBCVT

The Bad Block Conversion program can be user to create a '.defects' file from
a textual representation of the paper copy of defects that accompany a disk
drive. To use the porgram, first create a file of the name mumble.raw_defects
where mumble is the HDA id that you desire the drive to be formatted as. 
In this file include all defects in the format:

cylinder,track,position,length

where: cylinder is the decimal cylinder number,
       track    is the decimal head or track number
       position is the decimal byte number position of the defect
       length   is the decimal bit length os the defect. ( use a length of
                   255 if the entire track is to be flagged defective ).
                   

       

After having created the file, invoke BBCVT from the CLI> promot by entering

    CLI> push BBCVT <return>
    
The program will prompt you for the HDA id and the type of drive you intend to 
use the '.defects' file with. The program will then display the geometry 
of the target drive and ask for confirmation. Then the program will create the
defect table and query the user for where to save the defect file. The defect
file will be named mumble.defects. You can use the CLI command create to enter
the file. If the file is large, you may experience the following error while 
entering the defect data:
    Abort : File system error
    Internal PAGE error FOOBAR
    From CLI
    Attempt to pop from level 0.
    
if so, use the size option with create to build a larger .raw_defects file
(see help for cli for more information).

a sample dialogue follows itis for a drive that will have a HDA id of
FOOBAR.

CLI> create/i/d foobar.raw_defects
)1,2,3,4
)500,3,4,5
))
CLI> push bbcvt
Enter HDA serial number as shown on HDA : foobar
Please enter the proper drive code from table:
   0 => Fujitsu 2351
   1 => Fujitsu 2361
   2 => Fujitsu 2333
   3 => Fujitsu 2344
   4 => Fujitsu 2372
Code : 4
This drive has 745 cylinders, 27 heads, 66 sectors
Is this information correct [Y] ?
Adding defect at cylinder => 1, track => 2, sector => 0
Adding defect at cylinder => 500, track => 3, sector => 0
Do you want to save this defect information on:
    0 => A tape
    1 => A DFS disk
Please enter 0 or 1: 1
CLI>

Remember you must enter ALL the defects known on the drive, this cannot be
user to flag specific error spots omn the disk.
