The CD-RW that came with my Sont Vaio computer malfunctioned. Best Buy installed a new one since it was under warranty. The new one is an Ultraspeed Memorex. My Computer shows it as a CD-RW and it has a recorder tab. The device manager however shows it as a CD-ROM. Nero5 was installed with the new drive. If I enable the recorder tab, it tries to write but an error message comes up saying it can't complete. If I diable the recorder tab, I get a G drive not accessable, wrong command. Short of returning it to Best Buy who took a week andd a half to install it, does anybody know if there is a simpler solution. Thanks.
