Disk Management guidelines
When managing disks and volumes:
■
Read the online Disk Management Help found in the utility.
■
Do not alter the Operating System Disk labeled Primary OS C: and Secondary OS D:.
■
Use meaningful volume labels with the intended drive letter embedded in the volume
label, if possible. For example, volume F: might be named “Disk F:.” Volume labels often
serve as the only means of identification.
■
Record all volume labels and drive letters in case of system Quick Restore.
■
When managing basic disks, only the last partition on the disk can be extended unless the
disk is changed to dynamic.
■
Basic disks can be converted to dynamic without bringing the system offline or loss of
data, but the volume will be unavailable during the conversion.
■
Basic disks can contain up to four primary partitions (or three primary partitions and one
extended partition).
■
Format drives with a 16 K allocation size for best support of snapshots, performance, and
defragmentation.
■
NTFS formatted drives are recommended since they provide the greatest level of support
for snapshots, encryption, and compression.
■
Only basic disks can be formatted as FAT or FAT32.
Note:
The Data Volume is configured by default as a hardware RAID-5 based basic partition across
all four disks and is formatted as NFTS with a 16K allocation unit size.
