Storage Medium

AutoPlay

The 744T can be set to play back all valid audio files in a directory. Files will play back in their order in the directory. Autoplay can be set with the following options:

Disabled – auto playback is off

Play all – all files in the directory will play, then stop when all files have been played

Repeat one – the selected file will play back, then continue until

Repeat all – all files in the directory will play in succession, then repeat until stopped by the user

Storage Medium – Internal Drive

The 744T’s internal hard disk drive is the 744T’s primary storage medium. The large capacity and fast data read/write speeds of hard drives are a perfect choice when long form, high data rate recording is performed. This is a good balance of speed, reliability, noise performance, and current draw. Higher speed drives may be used with the 744T, however they will not significantly improve performance. They will slightly increase transfer throughput with the penalty of increased current draw and reduced battery run time.

Formatting

The drive installed in the 744T is formatted at the factory as a single-partition FAT32 volume. If a drive with multiple partitions is installed, the 744T will only “see” the primary partion. The 744T can only address one partition.

As a matter of routine maintenance, periodic re-formatting of the 744T 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 directory corruption.

Be certain that all files on the 744T drive have been backed up to another media before formatting. Once formatted, all data on the drive will be erased.

To format the 744T internal hard drive:

1.Ensure that all data on the hard drive has been copied or is no longer needed.

2.Press the Menu key.

3.Use the Multi-Function Controller to scroll to InHDD:(Erase).

4.Press the controller button to begin formatting.

5.Press the controller once more to confirm the operation.

Formatting the 744T hard drive can take up to 30 seconds. When the format is completed, the 744T will create a fresh menu hierarchy, including the daily folder, if selected. Once you exit back to the main screen the 744T is ready for recording.

Drive Repair

Included in the software for the 744T is a basic drive repair utility. The utility is similar to Windows “Scandisk” and will check for file system integrity, recover lost cluster-chains, fix or recover damaged file allocation tables (FAT), and repair corrupted WAV files. This utility should be run after improper media removal, or in the event of a write error during recording.
