v. 2.67 Features and specifications are subject to change. Visit www.sounddevices.com for the latest documentation.

File detail is shown at the right side of the display. The center divider points to the ﬁle selected for

information viewing. Information shown includes:

• ﬁle creation date, ﬁle archive bit status, checked means the ﬁle archive bit is set, clear means

the ﬁle archive bit is cleared

• ﬁle creation time, ﬁle size

• number of tracks, bit depth, sample rate

• The length (LEN) of the ﬁle

The ﬁle directories always exit to the main screen whether entered via the menus or the HDD key.

File Time and Date

Similar to a computer ﬁle system, all ﬁles recorded by the 722 are stamped with the time and date of

ﬁle generation. To ensure that accurate time-of-day and ﬁle generation dates are written for each ﬁle,

make certain that the time-of-day clock and calendar are accurately set.

1. Enter the TIM E/DAT E: Set menu.

2. Set the current time and date using the navigation below.

Once set, the time and date clock will be kept while the removable rechargeable battery is attached.

If it is removed the internal AA NiMH time-of-day battery maintains the date for up to 5 days.

File Size Maximum

The 722 data volumes (internal hard drive and CF) are formatted and write to FAT32 ﬁle structures.

This structure allows these drives to directly mount in a wide variety of computer platforms, includ-

ing Windows, Mac OS, and Linux. Using the FireWire connection both internal drives (internal hard

drive and CF) appear as external FAT32 volumes.

Windows XP has a limitation on FAT32 drive formatting; XP can format a FAT32 volume to a maximum

of 32 GB, however it can read FAT32 volumes as large as 2 TB.

FAT32 has a maximum ﬁle size limitation of 4 GB. While it is possible to have thousands of ﬁles on

the 722 medium(s), the largest any single ﬁle may be is 4 GB. The 722 automatically splits an au-

dio ﬁle before the 4 GB size is reached and begins writing to a new ﬁle. When joined in an editing

program, these ﬁles match seamlessly with no samples lost. The 722 has menu-selectable ﬁle size

maximums of 512 MB, 1 GB, 2 GB, and 4 GB. The factory default setting for maximum ﬁle size is 2

GB. Some applications will not properly import audio ﬁles above 2 GB. The 512 MB size allows the

user to break an audio program into CD-R sized ﬁles for backup to inexpensive CD-R medium.
