Thanks again for the help. The link to supported drives on the web site doesn't seem to work any more though, is there any 2TB drives that are known to work well? Have to admit I hadn't come across the AFT before, aor all modern 2TB drives AFT?
Both my two DNS-323 work fine with two 1TB drives and 1.09 but I'm always short of space on tehm lately hence the thought of installing larger drives if possible,
An alternative I guess would be to buy an updated product to the DNS-323, is there anything comporable that works well? All I use them for is to backup my PCs and laptopt to.
Thanks,
Phill.
