Enviovos outras poucas dubidas. Estas corresponden ao USB Flash Memory Howto. Traduzoo porque teño problemas co meu pendrive (ou como queira que sexa como se lle chame en Galego) e este documento solucionoumas case todas (excepto como se recompila o kernel. Se alguen ao ler isto pensa en axudarme co kernel, que non me axude por agora porque non teño tempo nin para traducir e menos para amañar un problemiña). Como vin que hai bastante xente co mesmo problema ca min decidin traducilo. Este howto e relativamente novo (a primeira revision e de outubro do 2003) porque o problema tamen o e. A ultima version estable esta no LDP: tldp.org por se necesitades buscar o contexto. As dubidas estan segundo as atopei (a de enriba de todo e a primeira, e do fondo foi a ultima, polo de agora). Cheguei ata a paxina seis (incluida) da version HTML. A mais importante e a primeira porque aparece repetida unha chea de veces. Ata o howto se poderia chamar "Linux Memory Stick Howto":
memory stick explanation of the command options setting up a ext2 filesystem setting up a dual partition making a dual ext2/vfat system hotplugging and naming formalities feedback procedures for implementing USB Flash Memory devices making over-the-counter devices, pre-formatted for the MS Windows system, work on Linux formatting the device in the ext2 filesystem on a single partition and making it work The purpose of this is for situations where Linux + Linux and Linux + Windows are possible The procedures will not work if the write facility of the device is disabled (i.e. if the write protect switch is on). Neither has any attention been paid to adaptation of the procedures to other related operating systems. Use the camera's built-in menu system to do this reformatting for you. memory sticks or keychains keychain notebook computers an extension cable and a keychain. The latter provides a safe and with-it way of transporting the device. Over-the-counter memory sticks are usually formatted in vfat (msdos) The screen-like displays are precise copies of what appeared on my screen. The following support, relevant to this document, was compiled into the kernel. A modular approach may also be followed. Preliminary USB device filesystem (CONFIG_USB_DEVICEFS) In the lists above the entities in uppercase refer to the variable names to be found in the .config file in the upper level directory of the kernel source (/usr/src/linux/). The entities xxx.o refer to the modules created when a modular approach is followed. When there is no reference to a module, the option can only be hard-compiled into the kernel. Different kernel versions may have different indications of options when, for example, make menuconfig or make xconfig are run. Variables such as CONFIG_USB, which can be gleaned from the various help options, may be a more reliable indication. Very recent Linux distributions such as RedHat and SuSE probably have the appropriate kernel options compiled in. Under USB-support, options for a number of digital cameras are available. In this section we discuss in a very brief manner, The /proc filesystem serves as a window through which we can see the workings of a Linux setup. The objects of most interest for this document are the directories /proc/bus/usb/ and /proc/scsi/. These will be used to verify that the kernel had been set up properly for our purpose. SCSI disk devices are mapped to the /dev (devices) directory under /dev/sda , /dev/sdb , ... What will happen when both devices are present at boot-up, is not known. An overview of the partitions relevant to this document, the file /proc/partitions may be consulted. Under the Linux-2.6 series of kernels this problem may be very neatly resolved. as root, indicated by the hash The USB device filesystem. This dynamically generated filesystem should be mounted at /proc/bus/usb/ It is most versatile and sophisticated, carrying with it permissions (read-write-execute, who is permitted to do what), ownership (user, group, others), a timestamp (when last modified), etc. mount -t ext2 /dev/sda1 /mnt/memstick Mount in filetype ext2, device sda1 at mountpoint /mnt/memstick ls -l Make a complete list (modes, ownerships, etc.) mkdosfs -F 32 /dev/sda1 Create an ms-dos filesystem, FAT-size 32, on the partition /dev/sda1
