As soon I start my G-Raid 2TB I’m able to use my iMac for around 4 Minutes and then…freezes completely…the G-Raid is not visible in Finder.
The G-Raid is attached via Firewire/Thunderbolt adapter to my iMac.
When I attache the drive to my MacBoook (same cable, adapter etc) it works perfectly.
If I use the G-Raid with USB on my iMac it works fine.
I’ve spoke with the Apple support and they told me it should be a problem of the drive. I’ve told them it could not be. Because my iMac has HighSierra 10.13.2 and the MacBook 10.13.1…I told them it’s a HighSierra Update problem…
Apple told me to contact the G-Technology Support…
There is nothing we can do on our end. The issue is likely due to the FireWire interface. Even with using an adapter. FireWire is a legacy interface to Apple. Using it over USB will be your only option on that computer from now on. You’d need to get a new drive with USB 3.0 or direct Thunderbolt so you don’t have to use adapters.
