Removing a Hard-Drive Carrier 
The installation and removal procedures for the 3.5-inch hard drive and the 
2.5-inch hard drive are similar. Following is an example showing the 
replacement procedure of a 3.5-inch hard drive. 
CAUTION: Many repairs may only be done by a certified service technician. You 
should only perform troubleshooting and simple repairs as authorized in your 
product documentation, or as directed by the online or telephone service and 
support team. Damage due to servicing that is not authorized by Dell is not 
covered by your warranty. Read and follow the safety instructions that came with 
the product. 
CAUTION: To maintain proper system cooling, all empty hard-drive bays must 
have drive blanks installed.
