In Fedora 11 machine and Window machine I am able to mount and able to see the contents of CD / DVD. But in Fedora 14 I am unable to see its contents. When I insert CD / DVD it displays following message on screen: " You Have Just Inserted a Blank CD Choose What application to launch --> Open CD /DVD creator --> Open Folder " When I choose "Open folder" It shows CD is blank But its not a blank CD . I am able to see its contents in another machine with Fedora 10 there. Its a dual boot machine ( fedora 14 / windows ) . Able to see the contents of CD in Windows I installed fedora 14 using DVD. dmesg output ---------------------- [22345.187115] ata2.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 frozen [22345.187125] sr 1:0:0:0: CDB: Xdread, Read track info: 52 01 00 00 00 01 00 00 08 00 [22345.187149] ata2.00: cmd a0/00:00:00:08:00/00:00:00:00:00/a0 tag 0 pio 16392 in [22345.187152] res 40/00:03:00:0c:00/00:00:00:00:00/a0 Emask 0x4 (timeout) [22345.187159] ata2.00: status: { DRDY } [22345.187171] ata2: hard resetting link [22345.491819] ata2: SATA link up 1.5 Gbps (SStatus 113 SControl 300) [22345.498409] ata2.00: ACPI cmd e3/00:1f:00:00:00:a0 (IDLE) succeeded [22345.498757] ata2.00: ACPI cmd e3/00:02:00:00:00:a0 (IDLE) succeeded [22345.507349] ata2.00: ACPI cmd e3/00:1f:00:00:00:a0 (IDLE) succeeded [22345.507566] ata2.00: ACPI cmd e3/00:02:00:00:00:a0 (IDLE) succeeded [22345.509124] ata2.00: configured for UDMA/66 [22345.509516] ata2: EH complete [22347.223371] sr 1:0:0:0: [sr0] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE [22347.223380] sr 1:0:0:0: [sr0] Sense Key : Illegal Request [current] [22347.223388] sr 1:0:0:0: [sr0] Add.
