In a message dated 03/19/2003 3:51:58, I had originally written: << My 2400 is a wonderful machine. I upgraded it a while back to 400MHz, 10GB HD and 80MB memory. but it is totally useless for recording audio. The hard drive does a recalibration every 60 seconds, which interrupts the audio stream briefly. As you can imagine, this sucks in a profound way. Any workarounds, or do I need to just not use this baby for audio? David Reaves >> Having not gotten any response from this very knowledgeable group, I meanwhile have tried a few more things myself. I have an external (PCMCIA card) hard drive that I hooked up to see if I could isolate the problem to the internal drive. Well, the audio interruption also happens when the audio is playing from an external. And you don't even want to know the performance with a USB external drive! So, I ask, nay plead, does anybody know what's up with this brief audio interruption every 60 seconds? Is it endemic to the 2400? :-( David Reaves unhappy camper
