I'm not sure what's going on. When I first upgraded from Ubuntu 8.04 to 8.10 I could see my ROKR z6 in memory card mode, but now I'm getting buffer i/o errors. Nautilus sees the cards (phone memory and sd card), but can't mount them. --- similar issue - could I have an old driver from the upgrade interfering somehow - seems to be in the kernel though??: http://markmail.org/message/v5vtqcuujzjjhilx?q=rokr+Buffer+I/O+error+on+device+sdd%2C+logical+block+0+&page=1&refer=v5vtqcuujzjjhilx --- Motorola ROKR z6 - connection set to "memory card" Ubuntu Intrepid 8.10 Linux eklutna 2.6.27-11-generic #1 SMP Fri Jan 23 13:58:13 UTC 2009 x86_64 GNU/Linux lsusb | grep Moto output: Bus 006 Device 006: ID 22b8:6426 Motorola PCS dmesg output: [ 95.608076] usb 6-2: new high speed USB device using ehci_hcd and address 6 [ 95.746411] usb 6-2: configuration #1 chosen from 1 choice [ 95.750468] scsi7 : SCSI emulation for USB Mass Storage devices [ 95.753063] usb-storage: device found at 6 [ 95.753068] usb-storage: waiting for device to settle before scanning [ 100.752721] usb-storage: device scan complete [ 100.752950] scsi 7:0:0:0: Direct-Access Motorola MSnc. 0101 PQ: 0 ANSI: 2 [ 100.753116] scsi 7:0:0:1: Direct-Access Motorola MSnc. 0101 PQ: 0 ANSI: 2 [ 100.764892] sd 7:0:0:0: [sdc] Attached SCSI removable disk [ 100.765227] sd 7:0:0:0: Attached scsi generic sg3 type 0 [ 100.767092] sd 7:0:0:1: [sdd] Attached SCSI removable disk [ 100.767305] sd 7:0:0:1: Attached scsi generic sg4 type 0 [ 105.382675] sd 7:0:0:0: [sdc] 3841910 512-byte hardware sectors (1967 MB) [ 105.383417] sd 7:0:0:1: [sdd] 128671 512-byte hardware sectors (66 MB) [ 105.384164] sd 7:0:0:0: [sdc] Write Protect is off [ 105.384172] sd 7:0:0:0: [sdc] Mode Sense: 03 00 00 00 [ 105.384178] sd 7:0:0:0: [sdc] Assuming drive cache: write through [ 105.384903] sd 7:0:0:1: [sdd] Write Protect is off [ 105.384911] sd 7:0:0:1: [sdd] Mode Sense: 03 00 00 00 [ 105.384917] sd 7:0:0:1: [sdd] Assuming drive cache: write through [ 105.387788] sd 7:0:0:0: [sdc] 3841910 512-byte hardware sectors (1967 MB) [ 105.388542] sd 7:0:0:1: [sdd] 128671 512-byte hardware sectors (66 MB) [ 105.389289] sd 7:0:0:0: [sdc] Write Protect is off [ 105.389296] sd 7:0:0:0: [sdc] Mode Sense: 03 00 00 00 [ 105.389301] sd 7:0:0:0: [sdc] Assuming drive cache: write through [ 105.389313] sdc:<5>sd 7:0:0:1: [sdd] Write Protect is off [ 105.390040] sd 7:0:0:1: [sdd] Mode Sense: 03 00 00 00 [ 105.390046] sd 7:0:0:1: [sdd] Assuming drive cache: write through [ 105.390056] sdd: [ 105.398606] [ 135.537104] usb 6-2: reset high speed USB device using ehci_hcd and address 6 [ 135.714980] sd 7:0:0:0: [sdc] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_RETRY [ 135.714996] end_request: I/O error, dev sdc, sector 3841664 [ 135.715009] Buffer I/O error on device sdc, logical block 1920832 [ 135.741628] sd 7:0:0:1: [sdd] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_RETRY [ 135.741647] end_request: I/O error, dev sdd, sector 0 [ 135.741660] Buffer I/O error on device sdd, logical block 0 [ 135.741671] Buffer I/O error on device sdd, logical block 1 [ 135.741678] Buffer I/O error on device sdd, logical block 2 [ 135.741685] Buffer I/O error on device sdd, logical block 3 [ 135.741692] Buffer I/O error on device sdd, logical block 4 [ 135.741699] Buffer I/O error on device sdd, logical block 5 [ 135.741705] Buffer I/O error on device sdd, logical block 6 [ 135.741712] Buffer I/O error on device sdd, logical block 7 [ 135.741727] Buffer I/O error on device sdd, logical block 8 [ 135.749937] sd 7:0:0:0: [sdc] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK,SUGGEST_RETRY [ 135.749951] end_request: I/O error, dev sdc, sector 3841666
