Reading corrupt disks - GrabRange

Linden · **Joined:** Tue Sep 09, 2008 9:53 am **Posts:** 23

I'm having size issues when creating FileTrees with StarBurn_ISO9660JolietFileTree_AddPascalStream on a CD-RW at 702M + a bit the disk burns is unreadable but I assume the TOC fails (same file will create an ISO image of 737,130,496bytes) a smaller selection (ISO image - 736,868,352bytes) works just fine.

so 2 questions

1) how do I check the FileTree to see it will fit (I'm attempting to count allocations but am left with a MAYBE factor of 256K - 512K)

2) how can I read these corrupted disks (or any corrupted disk with no toc) ie a RAWGrabRange -

Quote:

GrabRange: Getting TOC information...
GrabRange: StarBurn_CdvdBurnerGrabber_GetTOCInformation() failed, exception 8, status 0, text "CStarBurn_ScsiTransportASPI::ExecuteCDB(): Command failed"

TIA

It's a very bad idea to burn more data on the disc then disc can handle. You cannot read what was not actually written. Read-by-sector features will not help you here.

Yes I agree that it's a bad idea... Oops just realized I'm not check StarBurn_ISO9660JolietFileTree_GetSizeInUCHARs result after building tree ... so this is whats causing my problem - SORRY for that one

BUT

I'd still like to do RAW sector reads using SB ON any CD/DVD (ie "ISO Buster Lite") is there a " Read-by-sector feature" THAT WILL help here.

TIA

1)

))

2) Sure. Please take a look at

StarBurn_CdvdBurnerGrabber_ReadLB(...)

API call. It can manually read disc content. Cooked. Or do you really mean RAW 2448 CD sectors?

Currently using ver 7 .. ReadLB will not read a disk which was written to be TrackAtOnceFromFree (which fails because tree is to big) ... same code is fine with OK disk.

Will version 10 fix this issue of is there another API (BTW I'd prefer cooked but can cope with RAW)

TIA

You cannot read the disc you've failed to finalize. TOC and lead-out is not written. Nobody will help you.

Ummmm..... ISO Buster 2.4 reads it fine

Good for it. Try using manual read from StarBurn.

ReadLB doesn't work is there another "MANUAL" read API

NB
1) the .h file comments includes references to StarBurn_CdvdBurnerGrabber_Read and StarBurn_CdvdBurnerGrabber_Read10 do they exist
2) .pas file does not contain ReadCooked - it does seem to work however... is it depricated

What does it mean "does not work"? Can we have the log?

They were either removed or renamed or made privite.

Test Media is a CD that has been creating by SB_CdvdBurnerGrabber_TrackAtOnceFromTree where tree is larger than disk.

Test program is a revised version of the GrabGange sample - TOC read is removed - and GrabRange function swapped with ReadLB

getmem( LRBuffer, 8192 );
l__EXCEPTION_NUMBER := StarBurn_CdvdBurnerGrabber_ReadLB(
l__PVOID__CdvdBurnerGrabber,
PCHAR( @l__CHAR__ExceptionText[1] ),
sizeof( l__CHAR__ExceptionText ),
l__ULONG__Status,
@l__CDB_FAILURE_INFORMATION,
17,
LRBuffer,
8192 );

Using readCooked instead of ReadLB ie
l__EXCEPTION_NUMBER := StarBurn_CdvdBurnerGrabber_ReadCooked(
l__PVOID__CdvdBurnerGrabber,
PCHAR( @l__CHAR__ExceptionText[1] ),
sizeof( l__CHAR__ExceptionText ),
l__ULONG__Status,
@l__CDB_FAILURE_INFORMATION,
LRBuffer,
8192,
17,
2 );

Works fine with valid data in LRBuffer

I need complete StarBurn log zipped and sent to support@rocketdivision.com. Your one is incomplete and truncated thus I have no idea what to do with it.
