Hard Drive NOTICE: Do not attempt to install a SAS hard drive in a 5.25-inch drive bay. These drive bays will only support a SATA hard drive, a CD/DVD drive, a floppy drive, or a Media Card Reader. NOTICE: If one SATA drive and any SAS drives are installed, the SATA drive must be the boot drive and should be installed in a 5.25-inch drive bay. NOTICE: It is recommended that you only use SAS cables purchased from Dell. Cables purchased elsewhere are not guaranteed to work with Dell computers. Drive numbering is marked upon the chassis beside the hard-drive bays. Removing a Hard Drive (Hard Drive Bays 1-4) CAUTION: Before you begin any of the procedures in this section, follow the safety instructions located in the Product Information Guide. CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before removing the cover.
