Ubuntu掛載U盤問(wèn)題
在終端(非圖形界面)掛載U盤，遇到一系列問(wèn)題：
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

This doesn't look like a partition table
Probably you selected the wrong device.

Partition table entries are not in disk order
老是說(shuō)special device /dev/sdb1 does not exist，無(wú)比郁悶
我以為是前幾天量產(chǎn)優(yōu)盤，優(yōu)盤的分區(qū)表搞出問(wèn)題了。
又發(fā)現(xiàn)：
#fdisk /dev/sda
然后輸入a，確定，再輸入w，確定。
接著就可以mount了。
估計(jì)

是有個(gè)?這個(gè)咚咚。。。。
量產(chǎn)優(yōu)盤，優(yōu)盤分區(qū)表問(wèn)題大大的有了。我當(dāng)時(shí)沒(méi)備份分區(qū)表，把它量產(chǎn)成活動(dòng)的，用來(lái)做啟動(dòng)盤，在windows下也沒(méi)什么問(wèn)題，就沒(méi)想到它在linux很難識(shí)別該U盤。
如果大家想量產(chǎn)的話，建議先紀(jì)錄量產(chǎn)前的u盤的信息，推薦用chip genius（查看vid、vid\\序列號(hào)之類）還有PowerQuest Partition Table Editor（查看修改分區(qū)表）還有Eisoo DiskGenius(磁盤管理修復(fù)) ，備份分區(qū)表和詳細(xì)信息，否則想恢復(fù)的時(shí)候可能就很麻煩。
我裝了autofs服務(wù)：
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.
最后：
flc@ubuntu:~$ sudo mount -t vfat -o iocharset=utf8 /dev/sdb /media/udisk
分區(qū)不要1 ？，掛載成功！
自動(dòng)掛載windows分區(qū)
如果你的電腦裝了Windows/Ubuntu雙系統(tǒng)，你該有這樣的體會(huì)：當(dāng)?shù)卿沀buntu時(shí)，系統(tǒng)不會(huì)自動(dòng)掛載Windows下的各分區(qū)，只能手動(dòng)掛載。這難免有些麻煩，并在一定意義上違背了Ubuntu追求簡(jiǎn)潔的宗旨。本文將介紹如何解決這個(gè)問(wèn)題，以使在登錄Ubuntu的同時(shí)自動(dòng)掛載Windows分區(qū)。
1.查看電腦中所有硬盤的分區(qū)情況。
命令如下：
sudo fdisk -l
此命令將輸出類似如下的信息：
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分別代表Windows中的C、D、E、F分區(qū)，并記下各分區(qū)的文件系統(tǒng)類型。
2.修改/etc/fstab配置文件。
命令如下：
sudo vi /etc/fstab
編輯此配置文件，最終其內(nèi)容類似如下：
# /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行是添加的內(nèi)容。其中/dev/sda1一行代表C盤分區(qū)將自動(dòng)掛載到/media/win-C目錄下，文件系統(tǒng)為NTFS（如果步驟1中查看分區(qū)的文件系統(tǒng)為FAT32時(shí)，此處請(qǐng)寫vfat），字符編碼為utf8。umask表示文件目錄的權(quán)限，此參數(shù)以及之后的2個(gè)參數(shù)都為0即可。以下幾行以此類推。此處可以選擇性的添加需要自動(dòng)掛載的分區(qū)，不想掛載的分區(qū)不用書(shū)寫。
3.重啟電腦。
編輯、保存上述配置文件之后，請(qǐng)重啟電腦。你將會(huì)看到系統(tǒng)已成功掛載Windows各分區(qū)。
