#1 Burning Software

1. How to know if the disc is blank (no track or has one blank track )?

2.Can i get total space and free space (MB) of the disc?

3. If do a quik erase how to get the process progress ?

Thank you.

Q2:
Convert m__UCHAR__LastPossibleStartTime(Packed Array[ 1..4 ] Of Byte;) to unsigned long,
I'm sorry ,I still do not know how to Convert.

Q3.Which parameter point out the size of TOC?

TOC_INFORMATION = Packed Record
m__BOOLEAN__IsValid : Boolean;
m__BOOLEAN__IsDVD : Boolean;
m__USHORT__ProtectedDVDRegions : Word;
m__UCHAR__BusKeyForDiscKey : Packed Array[ 1..5 ] Of Byte;
m__UCHAR__NumberOfSessions : Byte;
m__UCHAR__NumberOfTracks : Byte;
m__UCHAR__NumberOfUnsortedEntries : Byte;
m__TOC_ENTRY : Packed Array[ 1..NUMBER_OF_TRACKS ] Of TOC_ENTRY;
m__FULL_TOC_ENTRY_RAW : Packed Array[ 1..NUMBER_OF_TRACKS ] Of FULL_TOC_ENTRY_RAW;
m__FULL_TOC_ENTRY_RAW__Unsorted : Packed Array[ 1..NUMBER_OF_TRACKS ] Of FULL_TOC_ENTRY_RAW;
End;

Q2; I have tested


(m__UCHAR__LastPossibleStartTime[4]<<24) +
(m__UCHAR__LastPossibleStartTime[3]<<16) +
(m__UCHAR__LastPossibleStartTime[2]<<8 +
(m__UCHAR__LastPossibleStartTime[1])


I got 0 from CD-R(full of data) and DVD-RW(blank) , i think if you add
a parameter in DISC_INFORMATION Struct to point out total size of disc
(CD/DVD) will be easier to use .

thank you.
