“My Sony IDE drive is not being detected by the Windows® operating system.Connect the CD-RW drive to the secondary port as master. Make sure the jumper on the back of the drive is set accordingly. Obtain the latest bus-mastering drivers, and ensure that UDMA is turned off on the port the CD-RW is connected to.”
“Where do I get the latest drivers for my internal IDE Spressa CD-ReWritable drive?
Sony IDE Spressa CD-ReWritable drives use the standard drivers included in the Windows operating system. These Spressa drives do not require any additional drivers to be used to read CD's. The software that comes with the drives installs the necessary drivers for writing to CD.”
“Do I need a driver for my DVD-Rom?
Windows 95 & 98 have built in drivers for these devices, so an additional driver is not neccessary. However, if you received a branded kit (DDU220E/H, DDU220E/H2), there will be a Sony logo on the front plate and a DVD Decoder card made by Sigma Design. In this case there is an included driver disk that is labelled "Hollywood Plus Drivers disk" with versions 1.2, 1.3, 1.5, 1.6, etc. The drivers can also be downloaded from Sigma's website www.sigmadesigns.com.”
