## Questions & Answers

**Q: How many RPM?**
A: I am 100% certain that the drive inside is 5400 RPM. The 4TB is a ASIN:B013HNYV8I WD Blue WD40EZRZ 5400rpm.See my review: https://www.amazon.com/review/R388G5P0ACHROS

**Q: I did not realize this has a a/c power cord. does it require a/c power to work or will the usb power it?**
A: I just setup my WD 10TB External Hard Drive yesterday as basically like a slave if you will and it works perfectly, lots of people will try to only connect it to the ac or some might try connecting to the 2.0 or 3.0 USP thinking more speed, the ac gives the speed better here, I have mine setup as an extra storage unit so don't want to see it near my Main hard drive in Devices, but it will set itself up a dozen times there also if you don't watch it close, so anyway I have the AC power cord plugged in that came with the External drive plus it is plugged into one of my USB slots if you will. I did have troubles with it trying to configure itself in my Windows 10 Desktop PC, and had to delete about a dozen extra bogus devices it named itself up as i.e. Ubee-DMS:10, then I formatted the 10TB storage unit, then unplugged from USB and restarted computer, then plugged back in the 10TB WD via usb into computer and PRESTO all worked as it was suppose to via the USB cables as a storage unit. When I Formatted the 10-TB WD AND IN DOING SO it Showed me it only had a capacity of 9.09TB and not the 10TB as the description showed I paid for, BUT 9TB or even 8TB would be just fine for me anyway.........

**Q: my house has 210-240v european sockets , will this fit with normal adapter or will it burn out because it from america?**
A: The Drives AFAIK are comfortable with 110v-240v. Im in Australia (240v) and seems to work fine. If you are concerned drop-in replacement adapters which have standard euro sockets (search mycartmax ebay) are about $8-10US, I would recommend a correct plug adapter anyway to avoid cheap international adapters. The price cannot be beaten (I study cryptography so go through a lot of drives) even adding in the cost of a replacement adapter the drive is a good buy.

**Q: ok, stupid question, if i unplug the power cord with my data still be saved?**
A: I think you are worried if you unplug the power cord is your data on the hard drive going to disappear permanently when you plug the power cord back?  If this is what you meant to ask yes the data will still be there if you saved the data and properly waited for it to write the data to the hard drive before unplugging the USB and power brick cable.  Do not turn off the power until either the data has been written or at least a minute has passed since any activity to the drive if you're really concerned.  The safest is to eject the USB drive from Windows and wait for it to say it is safe to unplug the device.  But since you can usually see the light flashing when it is reading or writing this will usually indicate it is safe to unplug.
