Dear Silverkettle,
You could take out your ide hardrive and mount it via an adapter to either a pc or mac.
Better still, buy a ide to CF adapter of ebay and then a CF card. You can replace the ide drive with this setup and then easily transfer files to your DAW.
There is a programme called AW extract for the PC or Aware for the Mac you can get it here
http://happyharry.net/yamaha/The AWExtract (AWX) application was developed to be a tool for extracting .wav files from Yamaha AW4416 and AW2816 backup files. All audio tracks, regions and sample data can be extracted from an AW4416 backup file. All formats are supported, 16-bit at 48kHz, 16-bit at 44.1kHz, 24-bit at 48kHz and 24-bit at 44.1kHz.
The benefits of using AWExtract over using the AW4416 built-in 'wave export' function are many. The major advantage is the ability to extract all tracks from a single CD, where the AW4416 only allows a single wave file (mono or stereo) on a CD using 'wave export'.
