The expected, that's normal.

As workaround, you can download this file (you need the ecma program to unpack it, see the themabus' signature), dummy data which fills the 0,45000 gap. Then, copy /b dummy.bin+[your dump] [final file]. CDMage will be able to open the final file and scan for corruption, assuming that there are no audio tracks.

And if I were you, I would report this error to themabus, who developed the ice.exe app.

sarami has developed an alternative program which can process scrambled DC dumps:

http://forum.redump.org/topic/10483/discimagecreator/

For me, it's a promising program, due to D8 command support to rip and autodetect the offset correction to apply.

Could you verify if can dump the TOC+pregap without disc swapping as required for CDTool?

discimagecreator -ra h: 4 TOC+Pregap -5000 -76

Could you check if intelide.sys or pciide.sys is the driver loaded for your PATA controller?

Virtual CloneDrive and scrambled ccd/img/sub
Not fully supported. IsoBuster doesn't recognize any content of mounted into the virtual drive scrambled image, as a blank CD-R. Truman's CDTool can recognize the contents, but unfortunately there is no unscrambling on the fly.

Scrambled bin/cue image and Daemon Tools 3.47: No sucess.

[Disc]
TocEntries=4
Sessions=1
DataTracksScrambled=1
CDTextLength=0

I have burned a ccd/img/sub image (img file scrambled, 1 data track) successfully and the burned disc is fully readable. IsoBuster can open this image and shows its contents, too. Unfortunately, Daemon Tools doesn't support the scrambled ccd/img/sub image.

To dump CD based games with audio tracks I wouldn't suggest any modern drive. They usually lack of overreading capability.

Anyway as dumping drive, I would prefer any Lite-On drive, Mediatek based, rather a Hitachi-LG drive, Renesas chipset.

And I would consider the option of make external a decent internal drive, through a SATA+PATA to USB adapter.

You have to enter this range: -5000, 0. When the drive reachs -1000 LBA more or less will report a read error, but doesn't matter because TOC+pregap will be dumped.

-150,-76 range is not supported by Plextor drives.

To overread into lead-out an old Lite-On drive is better (without disc swapping I mean). My CRX220E1 and LH-20A1P can read both a maximum of 6749 sectors of lead-out (audio type). PX-W5224A only 100 sectors.

Of course, you can dump that range (main channel + subcode) to obtain a dump of a piece of lead-in (including the raw TOC stored in subcode) +  first pregap + a few of sectors of program area. As sample, I have dumped the -5000,0 range from my Alien Trilogy PC disc, drive used is a PX-W5224A:

Run the subdump program. This is the proper command line to dump the subcode from a LC disc: -mode 1 -fix 1 -rereadnums 25. -fix 2 could ruin the modified Q subcodes.

I have tested a few of drives. These are the results (disc tested is the european Battle Arena Toshinden):

Tool used is IsoBuster, except for the px716al-cdtoimgd8.bin dump. For this dump I have run cdtoimg j: scrambled.bin 24 and then unscramble -size=14874048 -offset=128 -output=PX716AL-CDtoIMGD8.bin scrambled.bin

The dump made by the GSA-4167B and DVR-107D has only a difference. The last sector of data track lacks of header field.

During the dumping process the PX-716AL drive (with ECC off unchecked) reported an error. I choosed replace user data with zeroes, and IsoBuster replaced the unreadable last sector with a fully zeroed mode 2 sector, but with sync and header.

The Sony drive (actually a Lite-On drive crossflashed to Sony firmware because Sony firmware enables overreading into lead-out) and HL GCE-8526B (both Mediatek based) can dump the data track without any workaround, just dump the proper range using IsoBuster.
