Who suffers most?
Features:

exclusively by the software. It does not rely on Windows to provide or
interpret the data and so can work completely independent from
Windows' limitations.
Supports Direct CD compressed files.
Supports formatted CD-RW discs mounted in very old drives that do not
know the CD-RW fixed packet format yet.
Why Does a CD become unreadable?
Compact Disc, a digital medium, normally formed of a 12cm
polycarbonate substrate, a reflective metalized layer, and a protective
lacquer coating. If this layer or coating is removed the CD gets
unreadable.
When ToC (Table of Contents) is damaged.
When data is not written on CD completely and CD is taken out from CD
Writer.
How to secure data loss in CDs?
Don't fill up the CD completely; leave some space for Table of
Contents (TOC), as it is written after data is copied.
Protect your CD from humid environment.
Protect CD from scratches and miss handling.
Do not create more than 8 folders in deep i.e. folder in another folder, as
some programs would not be able to read the data too deep.
Try to use CD-R only as they are more dirt-cheap and reliable.
While creating a CD, try not to open any other window.
Make sure when CD is being created, computer should not go in sleep
mode.
Don't write any thing on top of CD surface using a sharp pen. Do
not "cut and paste" to write data on CD.

FREQUENTLY ASKED QUESTIONS
How does QUICK RECOVERY work?
QUICK RECOVERY is a data recovery software. It bypasses the operating system,
calculates the system parameters internally, and searches for data heuristically.
After a brief analysis QUICK RECOVERY shows the recoverable files/folders.
Why cannot QUICK RECOVERY recover 100% data from bad sector?
When bad sector occurs in the area where files are saved, that means the
magnetic layer on which data is saved is removed. That's why its impossible to
recover the data from bad sectors. But rest of the portion of the file lying on good
sectors will be saved using Quick Recovery. Depending upon the type/structure and
extend of recovered data file would be opened in the respective package.
Why cannot QUICK RECOVERY recover 100% data from cracked disks?
The cracked disks generally can not be rotated in the CD drive, so Quick Recovery
would not be able to access CD media. Hence recovery is not possible.
