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.
