Region 8 Message headers
Region 10 Voice data
DEX tests each of the specified regions separately, starting with the lowest-numbered region through
the highest-numbered region. Up to six drives are tested.
When DEX finishes testing a region, it displays a status line:
REGION WW COMPLETE DISK #1: XXXXX DISK #2: XXXXX DISK #3: XXXXX
DISK #4: XXXXX DISK #5: XXXXX DISK #6: XXXXX
WW = Region tested.
XXXXX = Number of sectors on the disk had read errors.
All drives are listed on the status line, even if not installed. If not installed, zeros are displayed.
The form of the command is as follows:
@DEX x y
x = DISK This argument specifies which disk to test:
1
2
3
4
5
6
FF
Enter
If all disks are specified, but not all are actually installed, DEX tests only those
disks that are actually installed. If an invalid option is specified, DEX responds
with:
INVALID DISK NUMBER or DISK EXERCISE ABORTED
If none of the specified disks are actually installed, DEX responds with:
DRIVE NOT INSTALLED
y = REGION
This argument specifies which regions to test:
1
2
4
8
10
Enter
Voice drives have two types of regions, Critical sectors and Voice data. When
running DEX to test all regions for all system and voice drives (i.e., DEX FF),
invalid regions of the Voice drives are ignored, but the corresponding regions on
the system drives are exercised.
