Best Free CD Recovery Utility

Unfortunately it is still common to encounter partially or entirely unreadable CDs. The causes are many, ranging from simple scratches through to partially written sessions. Important data might not be accessible anymore, reason enough to look into tools that can help with the recovery.

An ounce of prevention is worth a pound of cure. Audit your data. CDCheck and IsoBuster will complement your existing IT security and operational integrity. These products deliver operational benefits beyond risk management; they reflect an understanding of both the risks in data and the benefits of auditing.

IsoBuster supports all CD / DVD / BD / HD DVD formats and all common file-systems. You can rescue lost files from a bad or trashed CD or DVD disc, save important documents, precious pictures, video from the family, and your only system backup. This utility allows you extract any usable information on the CD (or DVD) to your hard drive. It works by bypassing Windows and talking directly to the hardware. As an added bonus it can read old sessions, decode multiple image file formats, recover data from quick formatted DVDs, and a host of other useful data recovery features. You can use most of the functions in ISOBuster for free, but it will cost you $30 to enable some of the advanced functions such as support for BD and HD DVD file systems.

An alternative is CDCheck, which can scan most CDs in a few minutes to tell you if the data is OK - this way, you don't have to find out the hard way that there is a problem. Plus you can use the time it takes for a scan to complete as indicator of the CD or DVDs overall health - even though files may not be recorded as damaged, slower results normally indicate a CD that is on the way out (expect longer times if there are more files on the CD). If a CD or DVD is showing files with damage, or you can no longer read a file in a drive, CDCheck can be switched to recovery mode and makes a full sweep of the CD or DVD, recovering lost files along the way. When parts of a file can't be fully recovered, the program will still recover any salvageable fragments.

CDcheck and ISObuster are programs that fix errors after the fact.
DVDisaster is different in that it is a preventive program. DVDisaster is a freeware program available for recent versions of FreeBSD, GNU/Linux, Mac OS X (Darwin), NetBSD and Windows operating systems. It will scan your CD's and DVD's checking for read errors and tracking read speed. The program can also be used to create an error correction file from a good CD or DVD for data recovery. When a CD or DVD is damaged, or has started to deteriorate, some parts of the data may be unreadable. Using the error correction file previously made by DVDisaster, data on the CD or DVD may be recovered.
