i used paragon backup recovery to backup my entire disk into 2 dvd disks.and checked the integrity of the archive on them .the result is ok.but when i tried to restore my entire disk from my backup on these 2 dvd disks,it failed.i got a error message"file i/o error".anybody knows why
There are 2 possible reasons: Restore can't read data from DVD or can't write data to your HDD. 1. Check your HDD health (if you can connect it to bootable system) via CHKDSK /r. It will mark bad sectors and show you in report if there are problems with your HDD. 2. Copy archives from DVDs to any external drive Create WinPE\Linux Recovery media Boot from Recovery media and manually find copied archives in Restore wizard.
well,i can not understand why restore can not read data from dvd.since i use the same dvd burner to check the integerity of the archive,and the result is ok.(that implys my computer can read data from the dvd disks properly)further more ,i did use linux based recovery media to boot from.and then i am sorry,i don't know what do u mean by "CHKDSK"?
Check disk or CHKDSK - is Windows utility IF you can connect or use your target HDD in Windows , you can use CHKDSK utility to check the drive. Run Windows command prompt and type : chkdsk X: /r where X: should be replaced with correct drive letter for all partitions on your target HDD one by one. If you can't check HDD in Windows, please try the second part.
