how to configurate G raid removable thunderbolt 3 using USB 3 on Windows 10?

G-Technology G-RAID & G-DOCK

Hi,

I would like to configure my new 16 Tb G raid removable thunderbolt 3 to be useable both on Win and Mac and be compatible with USB 3.

When I am trying to connect it using USB 3 and raid configuration utility from here:

https://support-en.g-technology.com/app/products/detailnew/p/89/~/g-raid-usb

It does not detect any G-tech storage Systems. When I tried using thunderbolt 3 utility on PC without thunderbolt 3, it didn’t find any drive either.

Problem is I don’t have a PC with thunderbolt 3 at the moment so would like to use G raid removable thunderbolt 3 with provided USB 3 cable.

Any suggestions how to configurate G raid removable thunderbolt 3 using USB 3 on Windows 10?

Thanks,

You only need the configurator if you wish to change the RAID.

The software you need is this one: G-RAID w/ TB3 Configurator for MAC or G-RAID w/ TB3 Configurator for Windows

After you have changed the RAID to RAID1 you can then initialize and format the drive as exFAT and it will work on both platforms.

Thanks for reply.

I formatted my 16 Tb G raid with thunderbolt 3 to ExFat using Win 10 (Raid 1).

Problem:
-macOS (Mojave, v10.14.3) does not mount it.

I tried mount in disk utility and terminal - here few lines:
ANNON-Pro:~ ANNON$ diskutil list

So the only error I get is:
“Error: -69767: …”

After lot of googling, it seems macOS X does not recognize large allocation unit sizes of exFAT, so it looks like I need to re-format with smaller allocation unit size, maybe under macOS X. The minimum seems to be 512k, default 2048k is maybe too big.

Does G-technology provide a drive to mount G raid formatted under Win 10 to ExFAT (default allocation unit size) to be mount with macOS X???

Thanks,

All of our units currently are MAC OS Extended (Journaled) out of the box. The default allocation size on exFAT is usually the only contention for perfect stability across both platforms.

Usually the exFAT from the Windows side runs quite smoothly. If it isn’t working in your situation then try doing the exFAT format on Mac and see if it works better for you.
