WINCHESTER SUPPLEMENT
The VERIFY Utility
Some operating systems will display bad sectors that are de-
tected during normal operation. This prompt will allow you
to enter the sector addresses that your system has detected
and add those to the bad sector table. Note, however, that
particular sectors may be identified by the operating system
with a logical address within a partition and may not represent
the same real sector as identified by VERIFY. Both CPIM-85
and Z-DOS report the same address as identified by VERIFY
and not a logical address within the partition.
To enter a bad sector address, type the address number
and press the ~ g g ] k e y. The prompt will reappear,
allowing you to continue to enter additional bad sector
addresses.
To end entering bad sector addresses, press the Q> key
and then the g~ g g ] k ey. The system will start testing
the disk and will display:
Beginning verification...
When the test is finished, the display will add:
...completed
to the end of the verification message. If no bad sectors
were located, the system will display:
No bad sectors located.
and then return to Z-DOS and display its prompt.
If bad sectors were found, then the system will display:
Bad sectors located. Tables modified.
This message tells you that there were bad sectors lo-
cated on your Winchester disk. However, they have only
been flagged at this time and you may continue to access
them, though you will probably experience difficultie
when your programs attempt to use those sectors.
