Hola, No consigo que un adapatador SATA a USB (cvusb-is) detecte un disco duro Seagate Barracuda 3000GB nuevo. Cuando hago lsusb si que me aparece el dispositivo: Bus 001 Device 000: ID 152d:2338 JMicron Technology Corp. / JMicron USA Technology Corp. JM20337 Hi-Speed USB to SATA & PATA Combo Bridge dmesg va soltando fragmentos como el siguiente (éste es el último): [21198.932025] usb 1-7: reset high-speed USB device number 15 using ehci_hcd [21199.155026] usb 1-7: reset high-speed USB device number 15 using ehci_hcd [21199.378019] usb 1-7: reset high-speed USB device number 15 using ehci_hcd [21199.601027] usb 1-7: reset high-speed USB device number 15 using ehci_hcd [21199.824024] usb 1-7: reset high-speed USB device number 15 using ehci_hcd [21200.047023] usb 1-7: reset high-speed USB device number 15 using ehci_hcd [21200.161537] sd 15:0:0:0: [sdf] Unhandled error code [21200.161543] sd 15:0:0:0: [sdf] [21200.161545] Result: hostbyte=DID_ERROR driverbyte=DRIVER_OK [21200.161548] sd 15:0:0:0: [sdf] CDB: [21200.161550] Read(10): 28 00 0f ff ff d8 00 00 08 00 [21200.161561] end_request: I/O error, dev sdf, sector 268435416 [21200.161565] Buffer I/O error on device sdf, logical block 33554427 fdisk -l Termina con este aviso: linux-z79f:~ # fdisk -l Disk /dev/sda: 320.1 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders, total 625142448 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00052d7e Device Boot Start End Blocks Id System /dev/sda1 2048 8386559 4192256 82 Linux swap / Solaris /dev/sda2 * 8386560 50331647 20972544 83 Linux /dev/sda3 50331648 415424511 182546432 83 Linux /dev/sda4 415424512 625141759 104858624 f W95 Ext'd (LBA) /dev/sda5 415426560 625121279 104847360 83 Linux WARNING: GPT (GUID Partition Table) detected on '/dev/sdf'!

Alguna idea? -- Josep M Solé
