The erase pattern value is the sector data value.
You can specify any value in hex.
Example, assuming you would like to write all 0's during the erase pattern chosen:
1. Open the disk erase script
2. Under [DISK] section, set the value as needed for Pattern
Example:
[DISK]
FirstDisk=1
LastDisk=8
Method=0
Pattern=0x00
BootLog=0
