Install and connect the mobile rack
Warning! Always handle storage devices with caution. Make sure that you’re properly
grounded by wearing an anti-static strap when you install any computer component.
If an anti-static strap isn’t available, touch a large, grounded metal surface for several
seconds to discharge any built-up static electricity.

rack and to the power supply.
• Connect the LP4 connector on the computer system to the LP4 power
connector on the mobile rack.
9. Connect the SATA data cable to the SATA data connector on the mobile rack and
to a SATA host port on the motherboard.
10. To congure a RAID mode, move the RAID setting switch to the RAID mode that
you want to congure.
11. Place the cover back onto your computer case.
12. Reconnect the power cable to the back of your computer.
13. Reconnect any devices or peripherals that were connected to your computer.

Computer or Computer with a drive letter assigned to it. If you install a brand-new
hard drive that doesn’t contain any data, you must prepare the hard drive for use.
Warning! When you complete the following steps, all of the data on your hard drive is
deleted. If your hard drive has data on it that you require, you should create a backup
le or use a dierent hard drive.

following:
• On your desktop, right-click My Computer and click Manage.
• On your desktop, right-click Computer and click Manage.

GPT isn’t compatible with earlier versions of operating systems. MBR is supported by
both earlier and later versions of operating systems.
4. Locate the disk that is labeled Unallocated. To conrm that the hard drive is the
correct one, check the drive capacity.
5. Right-click the section of the window that says Unallocated and click New
Partition.
6. Complete the on-screen instructions to initialize the hard drive in the format of your
choice.
When the hard drive is successfully installed, it appears under My Computer or
Computer with a drive letter assigned to it.
macOS
If you install a brand-new hard drive that doesn’t contain any data, you must prepare
the hard drive for use.
Warning! When you complete the following steps, you create a partition that uses the
entire hard drive space.
1. Do one of the following:
• In Spotlight, enter Disk Utility.
• Open Finder. Navigate to Applications and click Utilities. Open Disk Utility.
2. Select the hard drive and click the Partition tab.
3. Enter a name for the partition.

About RAID modes
The HSB225S3R support four RAID modes: RAID 0, RAID 1, Normal, and JBOD.
RAID mode Description
RAID 0 Stripe set
Splits data evenly across two or more drives
RAID 1 Mirror
Creates a redundant drive on the second drive for security
JBOD Allows you to access the drives as just a bunch of
independent disks.
Note: The motherboard or SATA host connector must
support the port multiplier to congure Normal raid mode.
SPAN Combines or concatenates two drives into one large
logical volume
Congure a RAID mode
Warning! When you congure a RAID mode, all of the data on your hard drive is
deleted. If your hard drive has data on it that you require, you should create a backup
le or use a dierent hard drive.
1. Disconnect the power to the mobile rack.
2. Move the RAID setting switch to the RAID mode that you want to congure.
3. Reconnect the power to the mobile rack.
Warning! Do not remove a hard drive from the mobile rack if the Activity/link LED
indicator is blinking red.
The time it takes to complete a RAID conguration will vary depending on which RAID
mode you selected and the size of the hard drives that you’re using.

Troubleshooting
I can’t access the data on my drive
If you’re using a RAID 0 or SPAN array and the process is interrupted or one or both of
the drives get disconnected, the array could become damaged and cause all of the
data on the drives to be inaccessible or lost. The Activity/link LED may be illuminated
blue and not indicate that an error has occurred is both drives are still operational
within normal parameters.
To resolve this issue, try the following to reset the array and reformat the hard drive:
1. Disconnect the power from the mobile rack.
2. Move the RAID setting switch to JBOD.
3. Reconnect the power to the mobile rack.
4. Do one of the following:
• Make sure that both hard drives are detected and formatted.
• If a port multiplier enabled SATA port or interface isn’t available, make sure
that you detect and format the hard drives one at a time.
5. Disconnect the power from the mobile rack.
6. Move the RAID setting switch to the RAID mode that you want to congure.
7. Reconnect the power to the mobile rack.
