CF-ATA command description
9.21
Translate Sector command (87h)
This command allows the host a method of determining the exact number of times a user
sector has been erased and programmed. The controller responds with a 512-byte buffer of
information containing the desired cylinder, head and sector, including its logical address,
and the hot count, if available, for that sector. Table 72 defines the Translate Sector
command byte sequence. Table 73 represents the information in the buffer.
