## Questions & Answers

**Q: has anyone tried 4tb hard drives in this unit? it states it supports it**
A: Yes:  WD Red 4TB, Linux, Fedora 20, GPT partition table, USB3, Intel NUC, the whole capacity of the drive shows up, no problems.Here's the smart data from the drive:=== START OF INFORMATION SECTION ===Model Family:     Western Digital Red (AF)Device Model:     WDC WD40EFRX-68WT0N0Serial Number:    WD-XXXXXXXXXXXXXXXXXXXXXXLU WWN Device Id: 5 0014ee 25e8d978cFirmware Version: 80.00A80User Capacity:    4,000,787,030,016 bytes 4.00 TBSector Sizes:     512 bytes logical, 4096 bytes physicalRotation Rate:    5400 rpmDevice is:        In smartctl database for details use: -P showATA Version is:   ACS-2 (minor revision not indicated)SATA Version is:  SATA 3.0, 6.0 Gb/s (current: 3.0 Gb/s)Local Time is:    Sat Aug 30 12:38:41 2014 PDTSMART support is: Available - device has SMART capability.SMART support is: EnabledFYI, I used "hdparm -J" to set the idle3 timeout to 120 seconds.  It did not brick the drive and appeared to work; however, I will express the strong caveat that is a dangerous operation.#  hdparm -J /dev/sdddev/sdd: wdidle3      = 120 secs (or 13.2 secs for older drives)

**Q: Is there any way to make these units turn on after a power fail w/o pressing the button? I tried the 3 sync modes and regardless of what the attached server does it seems I have to manually press the power on button to get these to start responding after a power failure (USB-3).**
A: A comment to Abi and Phillip on chaining UPS units: I think the issue is total current draw, and usually if someone is adding another UPS, they plan to draw that much more current through the system, and that would indeed be bad. In general, it is good advice not to chain UPS or surge power strips, given how people normally just keeping plugging things in until all outlets are occupied. 

But... if Abi is disciplined and only plugs the one thing into that chained UPS that otherwise would occupy a plug on the first UPS, I'm not seeing the problem. Maybe Abi should tape over or toddler-plug the remaining outlets on the chained UPS as a reminder to avoid dangerous current draw situations? The total load on the first UPS then is almost unchanged (modulo the power overhead of the chained UPS itself), and if there is some reserve capacity on the first UPS, that shouldn't be a problem. Is there some other consideration I am missing here?

**Q: If I install 4 x 4TB drives on this unit and connect it to my computer, I see 4 new USB hdds in my PC or just one big drive?.**
A: If you just install the drives and power on, they will show up as separate drives.  If you're using eSata, you can setup a RAID configration. (I use 3-3tb drives in raid 5)  You can also use Windows Storage spaces to 'unite' the individual drives into one drive.  Raid is faster though.

**Q: has anyone tried putting a 2.5" 1 TB HDD in this thing? Do I have to use an 3.5" adapter or can I just plug in the 2.5" HDD?**
A: Note:  A Normal adapter/brace will not work that you would used for mounting a 2.5 in a PC case.  The connections for the power and data transfer are fixed solid to the board in the back of the case.  A normal adapter will leave the 2.5 drive well short of the connections and you will need to run cabled for the power and data, very very short cables.  Additionally, the metal plate that functions to hold the drives in place will not fit snugly with the 2.5 drive adapter meaning it will float around in there just a little to make some noise.  Due to these reasons I would suggest only using it for 3.5 drives as they fit perfectly in the drive bays.
