Linux系統掛載FAT32的隨身碟

Linux系統掛載FAT32的隨身碟 Linux掛載隨身碟步驟如下 1：將隨身碟插入USB介面，檢查是否插好 2：用fdisk命令檢查分區和USB裝置資訊 [root@wgods ~]# fdisk -l Disk /dev/sda: 1000.2 GB, 1000204886016 bytes255 heads, 63 sectors/track, 121601 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System/dev/sda1 * 1 13 104391 83 Linux/dev/sda2 14 121601 976655610 8e Linux LVM Disk /dev/sdb: 4012 MB, 4012900352 bytes223 heads, 55 sectors/track, 639 cylindersUnits = cylinders of 12265 * 512 = 6279680 bytes Device Boot Start End Blocks Id System/dev/sdb1 * 56 640 3580928 c W95 FAT32 (LBA)Partition 1 has different physical/logical beginnings (non-Linux?):phys=(42, 17, 40) logical=(55, 23, 1)Partition 1 has different physical/logical endings:phys=(487, 222, 55) logical=(639, 6, 31) 通過上面資訊我們可以看出USB裝置是FAT32格式的，標識為/dev/sdb1 [root@wgods ~]# fdisk -l | grep FAT32/dev/sdb1 * 56 640 3580928 c W95 FAT32 (LBA) 3:在mnt目錄下先建立一個usb的目錄 [root@wgods ~]# cd /mnt/[root@wgods mnt]# mkdir usb 4：掛載隨身碟[root@wgods mnt]# mount -t vfat /dev/sdb1 /mnt/usb 掛載成功後，我們可以在/mount/usb下看到相關的內容。 5：卸載隨身碟 執行umount命令卸載隨身碟時，報如下錯誤“device is busy”，可以用參數l解決問題。當然你也可以用fuser命令解決問題。如下所示 [root@wgods ~]# umount /mnt/usbumount: /mnt/usb: device is busyumount: /mnt/usb: device is busy [root@wgods ~]# umount -f /mnt/usbumount2: Device or resource busyumount: /mnt/usb: device is busyumount2: Device or resource busyumount: /mnt/usb: device is busy [root@wgods ~]# umount -l /mnt/usb 問題解決 [root@wgods usb]# umount /mnt/usbumount: /mnt/usb: device is busyumount: /mnt/usb: device is busy[root@wgods usb]# fuser -m /mnt/usb/mnt/usb: 21123c 21158c 21180c 21182c 21223c[root@wgods usb]# ps -auxw | grep 21123Warning: bad syntax, perhaps a bogus '-'?
