Cheap, possibly unreliable data grave

This plate provides cheap 4TB disk space, our board made very early again with a damaged file system (HFS +) on an iMac, both on a Lenovo laptop (Ubuntu) on USB 2.0 connected problems.
The Linux tool "badblocks" found errors on the disk, it was then replaced by hesitation Snogard against a "refurbished" plate. She's fine, but we use them hardly.

A plate can go every now broken, alone so I do not give two stars.

The plastic casing looks cheap and can only stand upright, also is not very stable and could easily tip over on its side. That may possibly an ongoing drive certainly not so much.
There are also no on / off switch, so must always unplug the appliance and be hineingefummelt again.

I would not buy this board, rather spend a little more for a higher quality housing.

Update April 2015:
The exchanged drive now makes trouble, he says the Mac is unable to repair the file system and it depends a read only with the note that they should quickly secure its data.
We do this now, on a newly acquired 4TB drive from WD. The Hitachi I look then again, but I no longer trust her, what do you start with such a plate yet?
Now just a star.
