Replacing a Hard Drive
It is simple to replace a drive in your WD Sentinel server. First, make sure to go to the WD
Store to purchase a compatible replacement drive. For a complete list of approved drive
models, search for Answer ID 9443 in the WD Knowledge Base at

The drives in the WD Sentinel server are “hot swappable.” This means that the
WD Sentinel server can remain powered on while you replace the drive. Once you replace
the drive, the WD Sentinel server automatically reconfigures the RAID. (See “Find compatible
hard drives” on page 37.)
