because the Map Entries are sorted on the ‘Original Location’ field, moving the unused<br />
and defective Map Entries to the end of the descriptor.<br />
Because of these considerations and in order to keep the rules as simple as possible, no<br />
extra exceptions for the CRC Length rule of the ST are introduced, but the default rule<br />
specified in 2.2.1.2 and 2.3.1.2 are adapted in order to cope with the 16 bits overflow<br />
case. An extra benefit is that also the theoretical cases (LVD, LVID and USD) are<br />
covered by this rule.<br />
Changes:<br />
In the table 5.1 Descriptor Lengths add a row with:<br />
Sparing Table<br />
no max<br />
In 2. Basic Restrictions & Requirements replace:<br />
Descriptor CRCs<br />
by:<br />
Descriptor CRCs<br />
CRCs shall be supported and calculated for all Descriptors<br />
except for the Space Bitmap Descriptor. There is a CRC length<br />
special case for the <strong>All</strong>ocation Extent Descriptor.<br />
CRCs shall be supported and calculated for all Descriptors.<br />
There are exception rules for the Descriptor CRC Length of the<br />
Space Bitmap Descriptor and the <strong>All</strong>ocation Extent Descriptor.<br />
In 2. Basic Restrictions & Requirements remove row:<br />
Space Bitmap<br />
Descriptor CRC not required.<br />
