G-Raid & 2x G-Speed Studio XL no longer being recognized in Windows 10

Hi all,

For the last couple of years we have been very happy with the G-Raid Thunderbolt 2 and 2x G-Speed Studio XL’s running on our Windows PC’s. Only when switching from Windows 7 to Windows 10 our Thunderbolt 2 PCI’s (Asus ThunderboltEX2) were no longer being supported. After this we switched to Thunderbolt 3 PCI’s (Asus ThunderboltEX3) in combination with a Thunderbolt 2 to Thunderbolt 3 converter from Apple. Everything was back to normal.

The last weeks have been a mess however, as I have been struggling with reinstalling drivers/firmware, Windows updates, switching thunderbolt 2 cables, computers, opening up the pc’s to move around the Thunderbolt 3 PCI’s and cables on the motherboards (X99 Deluxe II and 2x X99 Deluxe 3.1) and also between the different pc’s. Sadly with no luck and we could really use some help.

Let me describe the situation:

Before the issue:
We power on the PC’s, both G-Speed Studio XL’s boot up at the same time and once we enter Windows we can access the drives. The G-Raid needs to boot up manually by pressing the power button and can then also be accessed in Windows.

We power on the PC’s, no G-Speed Studio XL boots up. When we press either of the Studio XL power buttons after accessing Windows they boot up briefly before shutting down again. Switching cables doesn’t help either. The G-Raid remains on but is only recognized when attaching the USB cable instead of the Thunderbolt 2 cables. When plugging the drives into my Macbook however, everything still works the way it should. But we have been working with the drives from Windows for years now.

Hopefully this is a well known issue with a simple fix. If anyone has the solution, or is experiencing problems similar to ours, please let us know.

Best regards,

We solved the issue. Read our fix in our other topic:
