Dear all,
On page 125 of ATA/ATAPI-6, clause 8.15.42 says that "if bit 2 of
word 82 is set to one, the Removable Media feature set is supported."
On page 127 of ATA/ATAPI-6, clause 8.15.43 says that "if bit 2 of
word 85 is set to one, the Removable Media feature set is supported."
The two bits in the IDENTIFY DEVICE response indicates the same thing.
In my recognition, the two bits have an OR relation because they do
not say "if the bit is clered to zero, the feature is not supported".
Even though they do not say " if the bit is cleared to zero, the
feature is not supported". I would like to know whether or not the
Removable Media feature set is supported if word82[2]=0 and word85[2]=1,
or vice versa?
Moreover, as the subject, Should or Shall word82[2] and word85[2]
have identical values in IDENTIFY DEVICE response?
The same duplication occurs for word83[13:0] and word86[13:0],
word83[1:0] and word86[1:0], word 84[5] and word86[5], and word84[1:0]
and word87[1:0].
Sincerly Yours,
Kepler
