dvdcopy.exe  will recover data from damaged disc to hard disk. Each scan will create a log of the damaged sectors of each damaged file. Each subsequent scan will use this log to retry the bad sectors. Each scan will half the size of the sectors read to narrow down the bad sectors, causing the recovery time to double for each subsequent scan. Sectors that cannot be read will be filled with zeros.

Each read error will be displayed with the time used to read the bad sectors, percentage completed, elapsed time, estimated time to completion for current file, the error, the file name, location of bad sector and number of bad sectors.

On subsequent scans, the number of good sectors recovered is displayed in <KB recovered>. The time and energy required to complete the scan doubles for each subsequent scan.

Pressing any key will stop the scan. With the log files, DvdCopy can be run on different DVD drives to recover the maximal amount of good data from a damaged disc. Press ctrl-s to pause or resume the scan.

Copy the recovered files to another hard disk to defragment the files.
