yes tried it, same result.. i have 2 old nas boxes.. both have no issues with any of my externals..

Are all your enclosures multiple disk enclosures?

Are you saying that if you use 2TB drives or less it works fine but if you use 3TB drives it doesn't?

products should work as advertised, i appreciate you trying to stick up for them, and if this was a new technology, I would be much more understanding.. But as I pointed out, all my ext boxes worth with much older nas boxes.. therefore, as someone who works in the computer field, I consider their public release of this product to be a beta.. just not acceptable to me.

They've ported the RAIDiator OS to run on ARM hardware and given it a new redesigned web-interface. A lot of work has gone into this. I would certainly disagree with comments suggesting it's a beta product. If it was a beta lots of different things wouldn't be working and several bugs.

Now with existing USB disks there's also some issues to deal with such as:
Does it still mount when connected to another device?
What filesystem is on the disk? If the filesystem is an unusual one that's not recognised it may fail to mount. Filesystems such as NTFS, FAT32 (4GB limit per file) and EXT3 are recommended.
Have you verified the disks are in good health?
Does your USB enclosure have it's own power supply? If not, are you able to try connecting via a USB hub with its own power supply?
