Hard drive
For more information on hard drives, see the 512e and 4Kn Disk Formats whitepaper and 4K Sector HDD FAQ document at Dell.com/
dssmanuals .
All hard drives are connected to the server board through the hard drive backplane. Hard drives are supplied in hot swappable hard drive
carriers that fit in the hard drive slots.
CAUTION: Before attempting to remove or install a hard drive while the system is running, see the documentation for the storage
controller card to ensure that the host adapter is configured correctly to support hot swappable hard drive removal and insertion.
CAUTION: Do not turn off or restart your system while the hard drive is being formatted. Doing so can cause a hard drive failure.
Use only hard drives that have been tested and approved for use with the hard drive backplane.
When you format a hard drive, allow enough time for the formatting to be complete. Be aware that high-capacity hard drives can take a
long time to format.
