Hello,
There was an update provided that fixed the drop-out problem I think you are referring to. Here is the thread I posted to the FireStore forum. Also, when you do the update, make sure you do the System Reset (Utilities Menu) for the change to take effect.
Hope that helps.

FS-100 Update Now Available
Recently there have been reports from some FS-100 users of drop-outs during recordings. Unfortunately some units shipped from our production plant with an incorrect FireWire bridge chip configuration. Focus apologizes for this problem and inconvenience, and we assure you that these drop-outs are in no way related to drive performance or future reliability, but rather a simple software error which resulted in a buffer overrun.
We have corrected this problem and posted a software update here:
https://www.focusinfo.com/support/downloads.asp
We recommend that ALL FS-100 users load this updated software, as there is no harm in doing so even if your unit is set correctly. Please download the new software (follow the software update instructions on the READ ME enclosed in the zip file) and then do a System Reset (follow instructions on page 72 of the User Guide).
Best regards,
Focus Enhancements
