Formatting a hard disk drive
After installing a hard disk drive into the recorder, you must format the disk; otherwise you cannot
record or playback any data. Note that the following explanation assumes that the disk is
unformatted. If you want to know how to reformat a formatted disk, see the Reference manual.
1. Turn the power on.
The display will show the ROM version and time/date,
followed by [Initializing...] -> [Current IDE Drv] -> [(hard
disk model name)]. Then after [Unformat!] appears
momentarily, the recorder automatically accesses the Disk
Format menu in the SETUP mode and the following screen
appears.
2. Press the EXECUTE/YES key.
The model name of the currently installed hard disk
appears with a flashing [SURE?], asking whether or
not to format the installed hard disk. The model
name is shown in *** area in the example below.
Flashing
Be sure to connect the recorder to the power supply specified in the specification section of the Refer-
ence manual. Do not use an AC outlet of any other voltage.

Flashing 3. Press the EXECUTE/YES key again.
The display changes the screen for setting the sampling
frequency and quantization (default indication is [44.1kHz
24bit?]).
You can select a desired sampling frequency and quanti-
zation via the JOG dial from the following options;
[44.1kHz_24bit], [44.1kHz_16bit], [48kHz_16bit],
[48kHz_24bit], and [96k_24bit_8trk].
The following table may be helpful for you to make your
option.

A greater sampling frequency will reduce the available recording time/space after formatting. Under the same
sampling frequency setting, the greater quantization (bit number) reduces the available recording time.
The following table shows the "approximate available recording time" under each sampling frequency/quantiza-
tion. Depending on your medium, the available recording time may differ slightly. It will be a good idea to check
the available recording time. See “Checking the available recording time (REMAIN) on a formatted disk” on page 11.
Note that the available time values in the following table are based on a mono track recording.

Capacity
As shown in the table above, if you format the current drive at 96 kHz/24 bits, only eight real tracks are available,
even with the D1624. Also note that data recorded on the current drive of the D824 or D1624 which is formatted at
96 kHz/24 bits cannot save to an external DAT recorder or adat. See the Reference manual for details about the
save/load operations.
