Setting Location for External Drive using Volume ID
When working with external drives, it is important to identify them using a reliable and consistent method. Drive letters are not always reliable, as they can change depending on the order in which drives are connected to the system. A more reliable method of identifying external drives is by using their Volume ID.
What is a Volume ID?
A Volume ID is a unique identifier assigned to each volume (or partition) on a hard drive. It is a 128-bit number that is stored in the file system's metadata. Unlike drive letters, Volume IDs do not change, making them a reliable way to identify and refer to specific volumes.
Why Use a Volume ID to Set the Location of an External Drive?
Using a Volume ID to set the location of an external drive ensures that the correct drive is always used, even if the drive letter changes. This is especially important when performing script file operations on an external drive, as it eliminates the risk of accidentally performing those operations on the wrong drive.
How to Set the Location of an External Drive Using a Volume ID
To set the location of an external drive using its Volume ID, you can use the mountvol command in Windows or the mount command in Linux. The following sections show how to use these commands in more detail.
Using the mountvol Command in Windows
The mountvol command is a command-line utility in Windows that allows you to view and change the drive letters and Volume IDs of volumes on your system. To set the location of an external drive using its Volume ID, follow these steps:
- Connect the external drive to your system.
- Open a command prompt as an administrator.
- Type
mountvol[Volume ID][Drive Letter:]and press Enter. Replace[Volume ID]with the Volume ID of the external drive and[Drive Letter:]with the drive letter you want to assign to the external drive.
For example, if the Volume ID of the external drive is {346523ab-f26a-428c-a082-35e9315f394b} and you want to assign it the drive letter E:, you would type mountvol E: {346523ab-f26a-428c-a082-35e9315f394b} and press Enter.
Using the mount Command in Linux
The mount command is a command-line utility in Linux that allows you to mount file systems and set their mount points. To set the location of an external drive using its Volume ID, follow these steps:
- Connect the external drive to your system.
- Open a terminal window.
- Type
sudo blkidand press Enter. This will display a list of all the block devices on your system, including the external drive. Identify the external drive by its Volume ID. - Create a mount point for the external drive. For example, you can create a mount point at
/mnt/externalby typingsudo mkdir /mnt/externaland pressing Enter. - Type
sudo mount -U [Volume ID] [Mount Point]and press Enter. Replace[Volume ID]with the Volume ID of the external drive and[Mount Point]with the mount point you created in step 4.
For example, if the Volume ID of the external drive is /dev/sdb1 and you
