Formatting
The drive installed in the 722 is formatted at the factory as a single-partition FAT32 volume. If a drive
with multiple partitions is installed, the 722 will only “see” the primary partition. The 722 can only
address one partition.
As a matter of routine maintenance, periodic re-formatting of the 722 hard drive is recommended.
Formatting the hard drive rebuilds the FAT (file allocation table) and erases any audio or other data
files present on the medium. This reduces possibility of corruption and reduces the possibility of
fragmented audio files.
Be certain that all files on the 722 drive have been backed up to another media before formatting. Once
formatted, all data on the drive will be erased.
To format the 722 internal hard drive:
1.
Verify that all data on the hard drive has been copied or is no longer needed.
2.
Press the Menu key.
3.
Use the Rotary Switch to scroll to
In HDD: Erase / Format
.
4.
To verify that a non-recoverable format of the storage device is desired two keys must be pressed to
begin formatting. Press and hold down the play key to enable the check mark. Hit the tone key (check
mark) to begin formatting.

formatting
Formatting the 722 hard drive can take up to 30 seconds. When the format is completed, the 722
will create a fresh menu hierarchy, including the daily folder, if selected. Dynamic lists such as track
names, scene names, folder options, etc... will be saved.
Drive Type
The 722 ships with a 2.5-inch SATA interface, 5400 RPM hard drive. Sound Devices has chosen the
specific mechanism for maximum vibration and shock resistance. Most 2.5 inch drives conforming to
the SATA specification can be substituted for the factory hard drive.
Units with serial numbers below 471309092000 have a 2.5-inch ATA-5 interface, 5400 RPM hard drive.
Most 2.5 inch drives conforming to the ATA specification can be substituted for the factory hard drive.
When choosing a substitute hard drive, note that higher RPM hard drives draw more current, reduc-
ing battery run time. Higher speed drives may be used with the 722, however they will not signifi-
cantly improve performance. They will slightly increase transfer throughput with the penalty of
increased current draw and reduced battery run time. The 722 can address drives with capacities up
to 2 TB.
