    WINCHESTER DISK DRIVES A Winchester Disk Drive System, such as the one in your Z-100 Desktop Computer, is only one of a family of disk sys- tems generally called "hard disks." The disk itself is a carefully machined and polished non- magnetic metal platter that is coated with a magnetic material, similar to that used by floppy disks and audio and video tape.
  • Page 6 Page 5 WINCHESTER SUPPLEMENT Hardware Features The "read/write" head (which records and "reads" information to and from the surface of the disk) "floats" on a cushion of air above the disk as it turns. The distance between the head and the surface is so small that even a tiny smoke particle could cause irreparable damage to the disk.

    It is also possible that it may not have been prepared or partitioned, although this will normally be done before the Winchester ttCP/M-85is a registered trademark of Digital Research, Inc. ' Z-DOSis a trademark of Zenith Data Systems Corporation.

  • Page 10: The Utilities

    This utility should be used whenever you move your Desktop Computer, even a short distance. You should read pages 2.5 to 2.7 of the Z-100 Series User's Manual and then boot your Winchester Utilities disk as de- scribed in the "Power Up" section of this supplement. When you see the Z-DOS prompt on your screen, you are r eady to run PREP, PART, SHIP or VERIFY.

  • Page 11: The Prep Utility

    The surface of the Winchester disk must be initialized before you can use it in a system. This is similar to the FORMAT command and procedure discussed in the Z-100 Series User's Manual, except that typical operating system information (headers, labels, boot code and directories) for a specific sys- tem is not written onto the disk.

  • Page 12: Features Of Prep

    CAUTION: Using PREP will destroy all the files that may exist on your Winchester disk. Winchester disks supplied by Zenith Data Systems or Heath Company will normally have been prepared with PREP at the factory. If your disk has been pre- pared, you will need to use PREP only if you consistently encounter an unreasonable number of disk access errors.
  • Page 13 Then PREP displays messages as it operates on the disk. CAUTION: Using PREP will destroy all f i l e s on your Winchester disk. Winchester disks supplied by Zenith or Heath are normally prepared by PREP before they are shipped. Users of these disks will need to use PREP only if they are consistently encountering an unreasonable number of disk access errors.
  • Page 14 page 13 WINCHESTER SUPPLEMENT The PREP Utility If you press the g] key, the program will be halted and control of the Computer will be returned to Z-DOS. If you press the Q key, PREP will continue operation. To exit PREP, press the g] key. The Z-DOS system prompt will be displayed.

However, since the inner tracks have a smaller circumference, the bits are closer together and precompensation is requried to maintain ac- ceptable reliability.
  • Page 17 Page 16 WINCHESTER SUPPLEMENT The PREP Utility Now the disk will be tested seven times. Each test is known as a "pass." The seven passes of the test that are now per- formed are conducted to check the integrity of the disk's stor- age capacility.
  • Page 18 page 17 WINCHESTER SUPPLEMENT The PREP Utility During the test passes, PREP kept a record of any bad sec- tors. After the tests are finished and the superblocks have been written, PREP will write the bad sector table. As with the superblock, the table is recorded twice, each with a sepa- rate read/write head.

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.
  • Page 22 page 21 WINCHESTER SUPPLEMENT The VERIFY Utility You should now back up your Winchester disk with the BACKUP utility and then reformat your disk partitions using the appropriate operating system(s). This operation will "lock out" the bad sectors so that you may be assured of continued high performance from your Winchester sys- tem.

    Each has been assigned a disti nct name: CPM and Z-DOS. Both represent popular operating systems that are sold by ZDS for the Z-100. Therefore, you do not need to run PART before you can use your Winchester disk. If two equal partitions meet your needs, then proceed to the "Instal-...
