ADMINISTRATOR AND MAINTENANCE GUIDE
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 http://support.wd.com.
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 replaced,
complete the steps outlined in “Recovering from a Failed Drive” on page 48 to integrates the
new drive into the RAID array.
