This application is an alternative to Adaptec’s ASPI and to Elaborate Bytes’s ElyCDIO.
ASPI stands for Advanced SCSI Programming Interface.
This interface is necessary for ASPI drivers in order to communicate with ATAPI and SCSI devices because Windows software has been created without the capability of accessing these devices directly.
This software engine works as a device driver for Microsoft Windows and it ensures low-level access layer for CDs and DVDs. It is manufactured by VSO and it uses ASPI drivers to communicate with SCSI and ATAPI devices such as hard disks.
One of the applications of files contained in an ASPI layer is ripping audio CDs or burning CSs in systems that don’t have a SCSI adapter or device.
Patin-Couffin Access Layer is preferred by some users due to a series of advantages, compared to ASPI layers. Patin-Couffin Access Layer 37 is free and you know you can use it indefinitely; it is more reliable than its alternative; it has a mechanism which grants exclusive access to a given drive, ensuring a reliable read and write operation; it acts faster on drive; it supports hot plug and it can detect USB units and firewire hard drives.
All things considered, Patin-Couffin Access Layer is a reliable solution for accessing ATAPI and SCSI devices and enjoying the features of applications which remove CD and DVD protection, such as DVD43. It “weighs” less than 1 MB and it fits just perfectly in your system.
