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.

<CAUTION>

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.

1. Turn the power on. Flashing Flashing

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 E-IDE hard disk name will be displayed and, “SURE?” and “?” will flash.

3. Press the [EXECUTE/YES] key.

The display changes the screen for setting the sampling frequency and quantization (default indication is “44.1

kHz 24bit?”).

4. Select desired sampling frequency/quantization with the Jog dial (or [PREV] key/[NEXT] key).

For sampling frequency/quantization, other settings given in chart below can be selected in addition to the presently shown "44.1kHz 24bit."

At selecting the sampling frequency/quantization, be sure to refer to <Note> below.

The sampling frequency:

The sampling frequency and quantizing of the current drive (E-IDE hard disk) are setup dur- ing the formatting or reformatting process.

Consequently, all programs in the current drive will adhere to the sampling frequency used at formatting. You can change the format, how- ever, after compiling a program.

In other words, a variety of programs with dif- ferent sampling frequencies can be installed on the current drive. But alterable frequencies will be limited, depending on quantization at for- matting. For details, refer to page “23”.

Sampling frequency	44.1kHz		48kHz		88.2kHz	96kHz
Quantization	16 bits	24 bits	16 bits	24 bits	24 bits	24 bits
Number of available tracks	24 real tracks + 32 additional tracks				8 real tracks + 48 additional tracks

<Available recording time after formatting>

A greater sampling frequency will reduce the available recording time/space after formatting. Under the same sam- pling 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/quantization. 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	44.1kHz		48kHz		88.2kHz	96kHz
	16 bits	24 bits	16 bits	24 bits	24 bits	24 bits
10.0GB	Approx. 1888min.	Approx. 1258min.	Approx. 1735min.	Approx. 1156min.	Approx. 628min.	Approx. 577min.

<Note>

You cannot save audio data recorded in a 88.2kHz/24bit or 96kHz/24bit program using an adat digital signal. See the Reference manual for details about the save/load operations.
