write [media test-parameters]
The media argument writes to the device media by using various data
patterns. The patterns default to 0x39c39c39 for the first pass, 0xc6dec6de
for the second, and so on as shown in the last example. You must specify
transfer parameters that specify the media area to be written.
The following examples show the write media command:
