Ubuntu挂载U盘问题 复制代码 代码如下:flc@ubuntu:~$ sudo mount -t vfat -o iocharset=utf8 /dev/sdb1 /media/udisk mount: special device /dev/sdb1 does not exist flc@ubuntu:/$ sudo fdisk -l Disk /dev/sda: 32.2 GB, 32212254720 bytes 255 heads, 63 sectors/track, 3916 cylinders, total 62914560 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: 0x00082ba2 Device Boot Start End Blocks Id System /dev/sda1 * 2048 61868031 30932992 83 Linux /dev/sda2 61870078 62912511 521217 5 Extended /dev/sda5 61870080 62912511 521216 82 Linux swap / Solaris Disk /dev/sdb: 8011 MB, 8011120640 bytes 247 heads, 62 sectors/track, 1021 cylinders, total 15646720 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: 0x6f20736b This doesn't look like a partition table Probably you selected the wrong device. Device Boot Start End Blocks Id System /dev/sdb1 778135908 1919645538 570754815+ 72 Unknown /dev/sdb2 ? 168689522 2104717761 968014120 65 Novell Netware 386 /dev/sdb3 ? 1869881465 3805909656 968014096 79 Unknown /dev/sdb4 ? 2885681152 2885736650 27749+ d Unknown Partition table entries are not in disk order 老是说special device /dev/sdb1 does not exist，无比郁闷 我以为是前几天量产优盘，优盘的分区表搞出问题了。 又发现： 复制代码 代码如下:#fdisk /dev/sda 然后输入a，确定，再输入w，确定。 接着就可以mount了。 估计 复制代码 代码如下:Device Boot Start End Blocks Id System /dev/sdb1 778135908 1919645538 570754815+ 72 Unknown /dev/sdb2 ? 168689522 2104717761 968014120 65 Novell Netware 386 /dev/sdb3 ? 1869881465 3805909656 968014096 79 Unknown /dev/sdb4 ? 2885681152 2885736650 27749+ d Unknown 是有个?这个咚咚。。。。 量产优盘，优盘分区表问题大大的有了。我当时没备份分区表，把它量产成活动的，用来做启动盘，在windows下也没什么问题，就没想到它在linux很难识别该U盘。 如果大家想量产的话，建议先纪录量产前的u盘的信息，推荐用chip genius（查看vid、vid\\序列号之类）还有PowerQuest Partition Table Editor（查看修改分区表）还有Eisoo DiskGenius(磁盘管理修复) ，备份分区表和详细信息，否则想恢复的时候可能就很麻烦。 我装了autofs服务： 复制代码 代码如下:flc@ubuntu:~$ sudo apt-get install autofs flc@ubuntu:~$ sudo fdisk /dev/sdb Command (m for help): a Partition number (1-4): 1 Command (m for help): m Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only) Command (m for help): w The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks.
复制代码 代码如下:flc@ubuntu:~$ sudo mount -t vfat -o iocharset=utf8 /dev/sdb /media/udisk 分区不要1 ？，挂载成功！ 自动挂载windows分区 1.查看电脑中所有硬盘的分区情况。 复制代码 代码如下:sudo fdisk -l 此命令将输出类似如下的信息： 复制代码 代码如下:Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xf0b1ebb0</p> <p> Device Boot Start End Blocks Id System /dev/sda1 * 1 3825 30724281 7 HPFS/NTFS /dev/sda2 3826 60802 457661193 f W95 Ext'd (LBA) /dev/sda5 3826 16574 102406311 7 HPFS/NTFS /dev/sda6 16575 29323 102406311 7 HPFS/NTFS /dev/sda7 29324 54427 201647848+ 7 HPFS/NTFS /dev/sda8 54428 54552 999424 82 Linux swap / Solaris /dev/sda9 54552 60802 50199552 83 Linux 注：上述列表中/dev/sda1、/dev/sda5、/dev/sda6、/dev/sda7分别代表Windows中的C、D、E、F分区，并记下各分区的文件系统类型。 2.修改/etc/fstab配置文件。 复制代码 代码如下:sudo vi /etc/fstab 编辑此配置文件，最终其内容类似如下： 复制代码 代码如下:# /etc/fstab: static file system information. # # Use 'blkid -o value -s UUID' to print the universally unique identifier # for a device; this may be used with UUID= as a more robust way to name # devices that works even if disks are added and removed. See fstab(5). # # <file system> <mount point> <type> <options> <dump> <pass> proc /proc proc nodev,noexec,nosuid 0 0 # / was on /dev/sda7 during installation UUID=ac4326f1-50ad-457f-8e99-63174b97bc88 / ext4 errors=remount-ro 0 1 # swap was on /dev/sda6 during installation UUID=9026c543-3172-4d21-bce0-dbe595a1425d none swap sw 0 0 #auto mount windows fs /dev/sda1 /media/win-C ntfs nls=utf8,umask=000 0 0 /dev/sda5 /media/win-D ntfs nls=utf8,umask=000 0 0 /dev/sda6 /media/win-E ntfs nls=utf8,umask=000 0 0 /dev/sda7 /media/win-F ntfs nls=utf8,umask=000 0 0 注：末尾的5行是添加的内容。其中/dev/sda1一行代表C盘分区将自动挂载到/media/win-C目录下，文件系统为NTFS（如果步骤1中查看分区的文件系统为FAT32时，此处请写vfat），字符编码为utf8。umask表示文件目录的权限，此参数以及之后的2个参数都为0即可。以下几行以此类推。此处可以选择性的添加需要自动挂载的分区，不想挂载的分区不用书写。 3.重启电脑。 |
