Alphabetical list of options which are only intended for very special
situations and not for normal use:
.TP
.BI \--list_features
List the SCSI/MMC features which were obtained from the drive when it was
last acquired or re-assessed. Although this is better readable than the
raw reply to SCSI command GET CONFIGURATION, the MMC specification text
is still needed for interpreting it.
.br
The list consists of line groups of the form
.br
Code +/- : Name : Version,P/N
.br
Raw feature data bytes as hex numbers
.br
Parsed info as Name=Value pairs
.br
The headline is the only one which has no blank at its start.
Code is given as 16 bit hex number.
.br
"+" marks a currently offered feature. "-" marks those which may be offered
under different circumstances.
.br
Name is the feature name as listed in MMC specs.
.br
"P" marks persistent features. "N" marks non-persistent features.
.br
The Raw data can occupy more than one line. No "=" occurs in such lines.
If no raw data are present, one line with some blanks is listed instead.
.br
The Parsed info shows some extracted field values with names which resemble
the names used in the MMC description of the particular feature. Parsed info
lines contain at least one Name=Value pair. More than one line is possible.
If no parsed info is produced, one line with some blanks is listed instead.
.br
Example:
.br
0107 - : Real Time Streaming : 4,N
.br
1f 00 00 00
.br
RBCB=1 , SCS=1 , MP2A=1 , WSPD=1 , SW=1
.TP
.BI \--abort_handler
Establish default signal handling not to leave a drive in busy state
but rather to shut it down and to wait until it has ended the final operations.
