I am aware of the issues with DTS in MKVs, but I don't know which HDDs I can use with my 6606K/2.
I tried my 1TB external 2,5" and it didn't worked (tried it with power supply) --> It is shown "empty"
I tried 4GB USB Stick and it worked.
Is there any maximum partition size or anything?
On the TVs you can use every HDD. There is no Limit on the File Format or File Size and HDD Size.
(Supported Formats are FAT32 and NTFS)
The only thing is that you need to be aware of the Power. If you got a HDD which needs more power than usual (500mAh) you will get in trouble.
so i would say you should try another HDD or test this one on Different TV Sets (at retailer site).
