Procedure如何在不运行 vold 的情况下在 USB 海量存储设备中修改分区和创建 PCFS 文件系统

以下步骤介绍如何删除现有分区，创建新分区，然后在 USB 设备中创建 PCFS 文件系统。执行此任务之前，请确保先备份所有数据。

  1. 成为超级用户。

  2. 启动 fdisk 实用程序。

    例如：


    # fdisk /dev/rdsk/c3t0d0p0

  3. 通过选择选项 3 来删除分区。

    例如：


          Total disk size is 29 cylinders

             Cylinder size is 2048 (512 byte) blocks



                                               Cylinders

      Partition   Status    Type          Start   End   Length    %

      =========   ======    ============  =====   ===   ======   ===

          1       Active    Solaris2          1    28      28     97



SELECT ONE OF THE FOLLOWING:

   1. Create a partition

   2. Specify the active partition

   3. Delete a partition

   4. Change between Solaris and Solaris2 Partition IDs

   5. Exit (update disk configuration and exit)

   6. Cancel (exit without updating disk configuration)

Enter Selection: 3

  4. 选择要删除的分区号。

    例如：


          Total disk size is 29 cylinders

             Cylinder size is 2048 (512 byte) blocks



                                               Cylinders

      Partition   Status    Type          Start   End   Length    %

      =========   ======    ============  =====   ===   ======   ===

          1       Active    Solaris2          1    28      28     97



SELECT ONE OF THE FOLLOWING:

   1. Create a partition

   2. Specify the active partition

   3. Delete a partition

   4. Change between Solaris and Solaris2 Partition IDs

   5. Exit (update disk configuration and exit)

   6. Cancel (exit without updating disk configuration)

Specify the partition number to delete (or enter 0 to exit): 1



Partition deleted.

  5. 创建分区。

    例如：


          Total disk size is 29 cylinders

             Cylinder size is 2048 (512 byte) blocks



                                               Cylinders

      Partition   Status    Type          Start   End   Length    %

      =========   ======    ============  =====   ===   ======   ===



WARNING: no partitions are defined!



SELECT ONE OF THE FOLLOWING:

   3. Delete a partition

   4. Change between Solaris and Solaris2 Partition IDs

   5. Exit (update disk configuration and exit)

   6. Cancel (exit without updating disk configuration)

Enter Selection: 1

  6. 选择 FAT32 分区类型。


          Total disk size is 29 cylinders

             Cylinder size is 2048 (512 byte) blocks



                                               Cylinders

      Partition   Status    Type          Start   End   Length    %
