You can put files onto a blank disc by using a disc burning application,
such as
Dažreiz dators neieraksta datus pareizi, un tad nevarēs redzēt ierakstītās datnes, kad disks ievietots datorā.
In this case, try burning the disc again but use a lower burning speed, for example, 12x rather than 48x. Burning at slower speeds is more reliable.
