Here is a list of problem cases if you have access to the CD but there is no correct access to some or possibly all of the files/directories.
It is possible that you burned a Mixed Mode CD. Up to Nero 4.0.3.5, CD-Text can be activated for Mixed Mode CDs which however is ignored despite this.
As a general rule this error only occurs, if it is SCSI cabling error , or if the blank used is unsuitable (see Problematic blanks).
In contrast the problem only occurs if the CD Writer is damaged. This can sometimes be heard. If the burner is making funny noises, then a hardware problem is probably the cause. For CD-recorders such as Philips CDD2600, Philips CDD3610, HP4020, HP7100, HP7200 and compatible devices, porblems like this can be solved by replacing the spring (e.g. with the spring out of a ball-point pen)
In Windows NT up to SP§ some files on CDs can not be read. Please read the following article on this:
