The 788T's drives are formatted with the FAT32 file system, which is limited to a maximum possible file size of 4 GB minus 1 byte. To work with the limitations of FAT32, the 788T "splits" the files into 4 GB (or smaller) files when continuously recording, based on the menu selected in the recorder.
When the 788T's "File: Max Size" is set in its menu to "4 GBytes" the file size exceeds the 4 GB limitation and results in a brief loss of audio between file splits. This is typically less than five seconds.
Sound Devices recommends that users set the 788T's file size limit to "4GB CF (3.6 GB)". This setting allows the files to split at 3.6 GB, without a loss of audio. When matched up in an editing environment, these multiple files will be sample-continuous.
Note - This bug was fixed in Firmware Rev. 3.00
