Has anyone had problems with their 343 stuttering when the drive space begins maxing-out? Randomly, and for 5-15 seconds at a time,the 343 just stops streaming all data - this affects file transfers, media streaming, and printing functions - everything freezes simultaneously and then suddenly continues where it left off. I'm running both Vista 32 and 64 bit on various computers. This happens over all wired and wireless connections. The 343 is running 4 WD 500 GB drives in Raid 5, at 82% full. Firmware v 1.02. I'm fairly certain it's not the router (DIR-855), as I just updated the firmware/played with settings with no results. Nothing else has really changed over the last few months, other than loading more and more data on the drives. Other than drive space, I've exhausted most other options - any thoughts are appreciated.
