OK then - let me rephrase the question.

Has anybody installed a HDD larger than 500G and experienced issues when reaching the 500G mark?

Sorry, cannot remember. It was one I had lying around - from MSY origonally. Either WD or Seagate.

I would have to take the cover off to find out.

I had used it in a 4 drive RAID 1 arrangement for about a year untill I did an upgrade to 4x1.5T RAID-Z

I installedm an internal 1T HDD and it formatted NP and worked fine untill recently. Once it got to about half full the playback started to become jerky, especially when recording at the same time.

Anybody have any ideas?

The court case still upheld that Nine owns the copyright to its EPG data, just that ICETV doesn't infringe that copyright. As such there's no onus on Nine to share its version with anyone. If you write a book you can insist that no one can publish it as long as you hold copyright. Regards Peter Gil...
