IsoPuzzle 1.7 beta - Recovery program for scratched damaged DVD Data-CD
Do not use earlier versions – lot of bugfixes!

You need a working ASPI layer on Your system!
This program has been tested with the newest version of WNASPI32.DLL of NERO AG (Version 2.0.1.74).

Unfortunately NERO has removed their page where you could download this DLL together with the legal notice  ...
Please note, that the file WNASPI32.DLL is copyrighted by NERO AG.
It has to be copied to the application folder and MUST NOT be copied to your system folders.
It MUST NOT be used by other burning software!
The file is still located here
ftp://ftp6.nero.com/wnaspi32.dll

In some cases FROG ASPI would be sufficient (not for Win9x).

Short Description:
The goal of this program is to recover as much as possible data of damaged, bad burned or scratched CDs or DVDs.
This version supports only data CDs and DVDs with sectorsize of 2048 byte - Audio CD, VCD and SVCD are not supported.

How it works:
All readable data is stored in an "ISO" image file which can be read by various software such as "Daemon Tools", "WinRar" (needs iso-plugin) and most burner software like "Nero Burning Rom" etc.
Please note, that image files greater 4GB need to reside on a NTFS disk!
Every succsessfully read sector is stored in the image file (*.ISO) and will be marked "good" in the corresponding "flag" file (*.FLG).
If a read error is encountered a dummy sector will be written which will remain marked "bad". In this case a random number of sectors are skipped for faster progress.
Reaching the end of the disk a retry loop will be entered until all sectors have been read or a selectable "Give Up Time" has been reached.
After selecting the "Source" drive and the "Destination" folder the copy process can be started by pressing "Start".
The suggested filenames are taken from the DVDs volume label.
The copy process can be interrupted at any time by pressing the "Pause" button and can be continued by pressing "Start" again.
This way You can try to complete Your image file even on different machines with different CD drives - often one drive can read some sectors which are unreadable for an other one.
For using different drives You can share the image file *.ISO (together with the flag file *.FLG) on a network drive or put it on a portable disk (USB).

Import function:
To avoid dealing with very large files You can use the "Import" function:
Assuming that You started on machine "A" and no more data comes from Your DVD.
.) Copy ONLY (!) the *.FLG file (e.g. via USB stick) to machine "B".
.) On "B" select "Destination" folder, where the *.FLG is located.
.) "Start" will create an "import file" *.IMP in the same folder. All readable sectors are now stored here.
.) After completion on "B" transfer the *.IMP to a location where it is accessible from machine "A".
.) On "A" it can be merged into the existing *.ISO image with "Import File"
Force Disksize - WARNING - Use with care!
.) Some DVD drives report slightly different size of the same DVD/CD.
 For ripping to an existing *.Iso/*Flg pair (or *.Imp/*.Flg) You can set the disk size to "Flagfile reported".
 (You can try "Estimated" to get out, which drive is wrong ...)
.) In some cases "empty disk" is reported although the disk is readable.
 Setting the size to "Estimated" would be the choice here.
 This function may be slow and unreliable.
Be careful and be sure You know what You are doing when using this function!!!
By changing the (drive reported) disk size You might accidentially destroy an existing image file - make sure the given filenames are correct!

Cylce Tray:
It your responsibility NOT to change the disk while the tray is open!

Allow Cooldown:
Pause times are extended up to half an hour for cooling down the drive in case of long failure time. The tray will be opened if "Cycle Tray" is enabled.
Pauses can be aborted immediately by unchecking "Allow Cooldown".

History:
1.7 Extended single sector reading, Delete flag & import file on success
     Import function reviewed, Pause time decisions improved
     Lot of Bugfixes (probably last sector missing due to aspi(?),
     crash on more than 8 drives, unmountable disk prevents give up,
     possibly corruped flagfile on ripping attempt to locked image)
1.6 Bugfix (possible disk mounting problems after cycling tray)
     Try single sector reading when failure time exceeds
1.5 Force disksize now possible regardless unreadable sector 0, 
     Extended pause time for drive cooling,
     Save some settings on exit,
     Bugfix (last sector missing)
1.4 Added options: Cycle tray on multiple errors, Select iso-filename,
     Force disksize (solves "different sectornumber" and "empty disk")
1.3 Progressbar & other cosmetics
1.2 Crash on missing host-adapter-0 fixed
1.1 A few bugs corrected
1.0 First release
