Preparing and Formatting an ESDI Hard Disk without COMPSURF
The utility ESDIDISK was developed to prepare ESDI hard disks for
NetWare file servers. Running ESDIDISK and the manufacturer's format
utility for ESDI hard disks substitutes for COMPSURF.
With ESDIDISK you can:
o Run a track zero test on the first 32 sectors of the disk.
Error information generated during succeeding tests is saved
in these sectors.
o Run a sequential surface test to locate additional defects
not in the hard disk manufacturer's defect list.
o Run a random read-write test to check the functional
integrity of the hard disk.
o Place the COMPSURF stamp on a successfully-tested hard disk
so that 286-based NetWare will access the disk.
o Add sectors flagged "bad" during format (but not spared out)
to the NetWare bad block table.
o Test the hard disk and verify that the disk channel is
functional.
COMPSURF should not be run on the disk before or after running
ESDIDISK. ESDIDISK is available on NetWire as ESDIDR.ZIP.
