Cdrom.sys refers to a driver file that is part of Microsoft Windows. As its names suggests, cdrom.sys basically helps support the “CD-ROM” or compact disc read-only-memory functionality of the computer. For computers with so-called CD-ROM drives, driver files like cdrom.sys are needed for the CD and related media to be played and read correctly and efficiently. Without the cdrom.sys file, users will encounter errors when opening media through the CD-ROM.
Many people encounter the cdrom.sys file during computer startup. As part of the Windows operating system, drivers like cdrom.sys will be activated to search for possible media inserted into the CD-ROM drive. There are times, though, that this part of the startup or boot-up process may stall the computer or some other applications. When this happens, an error pointing to the cdrom.sys file may occur.
There are also times when the error points to corruption in the cdrom.sys file. Sometimes users also encounter errors that label the cdrom.sys file as actually missing. When these errors occur, users may not be able to successfully open media in their CD ROM drive. Sometimes, the drive itself will not be displayed when trying to view the ‘My Computer’ option. These problems are simply due to the fact that the actual driver file for the CD ROM and related devices or applications is corrupt or deleted from the system. Whenever the operating system calls out the driver file to perform its function, cdrom.sys won’t be able to do so.
For cdrom.sys errors, users are often advised to check which program or application triggers them. If people are familiar with program installation or configuration, they may try to reinstall the program in question to address problems concerning the cdrom.sys file. If the startup process is the only concern, a simple reconfiguration in the boot setup may also do the trick. Otherwise, consultation with computer technicians may be necessary.
