How do you disable the hard drive maintanance check in OS3.5?

Since I installed my Cyberstorm PPC and a SCSI drive with OS 3.5. and a fresh install of the Video Toaster Flyer system. My A4000D is now booting off the SCSI drive and the only thing on the on board IDE is the CD rom. My Flyer drives are continuiously doing a "maintance check" it sound like the drives are resetting the heads every 5 seconds when the system is idol.
I have asked around and it seems that it may be that OS 3.5 does a maintanace check causing this. Is there a way to disable this or does anyone know what else may cause this?

It only started after I installed the Cyberstorm and the OS on the SCSI drive attached to the Cyberstorm. When I had the system installed on the IDE it did not do this. So its not the Flyer system that is causing this.

Possibly but not in this situation as it has only started doing this since I put in my Cyberstorm and installed OS 3.5 It did not do this before as I have had the same Toaster Flyer system setup for years.

The Flyer drives are in a seperate Tower with there own 400w power supply also in this tower is the Two 2 channel TBCs. I have had this setup for 4 years and only once I installed the Cyberstorm and a SCSI drive with OS 3.5 in my A4000D has this problem started. There is no interuption of reading video or recording when the "clocking" or "checking" of the drives (whatever its called) is hapening.

Hey, Thanks for all your help guys. I figured it out. The OS 3.5 thinks the flyer drives are part of the workbench even though they are accessable they are not to be used that way. I got a suggestion from someone on a Toastr flyer forum to move the icons that represent the Flyer drives out of the Dev. folder and into the Workbench startup. and that fixed the problem.
