He visto esas unidades. En una SuSE 10.1 me montó sin problemas ambas (la partición que se puede escribir y la otra de sólo lectura). Creo que está relacionado con el U3:
Mejor: http://en.wikipedia.org/wiki/U3 Coincide: Hardware U3 smart drives are traditional USB flash drives with a specific setup: * Disk Management shows two drives; one emulates a read-only CD drive -- an ISO 9660 partition with the autorun and LaunchPad, and the other drive has a traditional FAT partition that includes a hidden SYSTEM folder with your installed applications. * Optional: U3 Compliant Applications Preloaded Hardware manufacturers can get the hardware development kit by emailing licensing@u3.org. [3] Compatibility The U3 Launchpad and U3 Applications will only run on newer Microsoft Windows Operating Systems (Microsoft Windows 2000 with Service Pack 4+, Windows Server 2003, and Windows XP). U3 does not work with Windows Vista. U3 website knowledge base says Vista support will only be available after Vista's official launch. Data will continue to be accessible from any OS capable of reading from USB Mass Storage Devices, unless the U3 device is password protected [4]. "If the OS in question can normally see ordinary USB flash drives, then the U3 smart drive removable mass storage area (domain) should still be available for standard file system activities unless it is a private area protected by a password." Así que en principio, debe ser accesible a no ser que esté protegido con password, o sea otro problema. Por cierto, el otro día me vino un amigo con un disco duro en usb, formateado como ntfs. El problema parece venir de que el kernel no reconoce las particiones y aunque creaba el nodo /dev/sda no creaba el sda1 - y si yo lo creaba a mano tampoco funcionaba, decía algo como que tenía acceso de escritura pero no lectura (se me han perdido el log de los comandos que metí, se fueron hacia arriba demasiado con un ls grande). En cambio, el fdisk no tenía problemas en ver la partición. ¿Tendrá relación?
