Hi,

My computers Hard disk was crashed last month then i have taken all the backup of data from computer on CD/DVD And my laptop. and replaced the hard disk and reinstall the XP but now some of the CD/DVDs are not readable by XP, i mean now some CD/DVDs show nothing in it (like blank CD/DVD) even there is data and not shows any errors..

Please let me know if there any tool that may recover the data from them there is very important data.

Thanks
Rahul

can they be read on any other computer?
It might be the drive is acting up.

Get yourself a CD/DVD cleaning disk and run that through your CD/DVD.
