4.2.2 Mount and Unmount Volumes
If the drives inside of each drive carrier are already formatted, you can begin using them right
away. When the RAX enclosure is properly connected and turned on, and each carrier is properly
installed, an icon representing the available data volume(s) will appear on the desktop. If any drive
inside of a carrier is unformatted, a message will appear on the desktop saying that that disk is
unreadable. Use Disk Utility to easily format it (see Section 4.2.1).
Unmount the volume before powering down the unit by dragging the volume’s icon to the
Trash
,
or by selecting the volume then pressing
C E
on your keyboard.
Disconnecting or powering off the RAX enclosure or ejecting a carrier while macOS is actively reading
or writing to the volume can result in data loss.
5 Frequently Asked Questions
Q: Does my 4-bay RAX unit support RAID?
A: The RAX425DC-XJ only supports JBOD functionality. However, the drives can be RAIDed in
software, or the RAX enclosure can be attached to a RAID host bus adapter (HBA) for hardware
RAID functionality.
Q: Will this product work with hard drives larger than 2.2TB?
A: Yes, assuming the rest of your configuration (e.g. OS, BIOS, host drivers) supports large volumes.
All modern secure operating systems and hardware support drives larger than 2.2 TB.
Q: Why is my hard drive experiencing data corruption?
A: Many things can cause data corruption on hard drives, whether they are inside your computer or
inside an external storage product. Malicious software, operating system bugs, failure to properly dis-
connect external devices, or no obvious reason at all. Data corruption or loss is therefore not covered
by warranty.
