Have you checked that...
You are not filling up your hard disk with	Ö
uncompressed digital audio. For example, one
minute of stereo sound recorded at a
resolution of 44 kHz will occupy about 10.5
MB.

How

Plug all devices into adjacent power outlets (outlets within 5 cm / 2 inches of each other), or use line filters

How

•Before recording, check that there is enough free space on your hard disk.

•Data compression can reduce the space required. The A-law and m-law hardware compression used by the audio interface enables the sampling of sound at a resolution of 16-bits, but it generates the same quantity of data as an 8-bit sample.
