I had archived some data on a dvd about a year back. Now I find that the data could not be read completely. I had picked up the data from a Linux based CVS Repository and also from a Windows XP based system. How do we verify the data if they are correct? I give below 3 of them. More comments required.
- While copying the data into a DVD, we can use “Verify” option of the tool that is being used to transfer data. Ex. Nero Burner.
- A CRC can be generated for each file and compared after the data is transferred
- After the data transfer, the same can be copied back to an alternate location
- Since the files are in a compressed mode (.zip / .tar), they zip tool can check the files for any issues.
Is there any fool proof way to do this ?
