You can use SoftRAID to label a disk. This label is only displayed in SoftRAID, and can be helpful for identifying your disks. You can also use the “Blink Disk Light” or “Identify” feature to make sure you are selecting the correct disk.
You can even select multiple disks and add a label to all of them. If you have more than one multi-disk enclosure, this makes it easy to keep track of which enclosure contains each of your disks.
Once you’ve added a label to a disk, SoftRAID will remember the label and always display it for that disk. It will also display that label on any error dialog or warning message for that disk.
