Akai S900/950

Hello, first post here.  I'm fairly new to the S950.  I also have an S1100 that I've had for awhile and am much more comfortable on so I am not completely new to samplers.

So my problem is saving samples to disk.  I am able to save a template program with new name, keygroups, etc... but when I try to save samples, I hear the disk drive whirring normally for a few seconds and then "OOPS! Bad data from disk" appears.  I was able to save samples in the past until now.  I tried saving to both DD and HD disks.  I get the same result from both.

Is the drive failing?  I'm confused on this because I can save data, just not sample data.

For what it's worth my drive activity light on the S950 is "red" and on the S1100 it's "yellow".  Is that normal?  Anyone?  Bueller?....Bueller?

Thx!
