Hard Drive Keeps Disconnecting

Hi there, I have a G- Technology 2 TB G- Drive mobile USB 3.1 Gen 1 External hard drive. I bought it last year. I have had nothing but trouble with it. It is constantly disconnecting from my Mac. It is plugged in with the USB cable, but the Mac thinks it keeps disconnecting. This makes it almost impossible to work with. I try to upload files and videos, and the constant disconnecting makes this very difficult. I have called the company and requested a replacement USB cable, and this hasn’t made any difference. The problem isn’t my Mac, because I have another hard drive I use with it and I have no problems at all.

The drive itself would need to be replaced. The disconnection is likely due to an issue with the interface board on the unit. You can generate an RMA for a replacement drive on our website here: RMA Creation

Okay thank you very much. I will return it for a replacement using that link. One question: should I send the usb cables with the drive when I send it back? Thank you.

You will get a replacement USB cable as part of the replacement accessories kit regardless. Won’t be necessary to include it.

I am having the same issue when trying to copy data to a different harddrive because the G-Technology Hard Drive is impossible to work with since the day I purchased it. All of the G-technology drives I have purchased are not good quality.

I have the same issue. On my PC (Win10 1909 build), drive keeps disconnecting during write operations (read seems to be fine).

But problem isn’t in the drive, and not in the cables, since it also works fine with my laptop (Win10 2004 build) with zero disconnects.

USB Power saving ofc off. Looks like some driver/OS issue. I’m using it so far as network drive via SMB to avoid disconnects, but it dramatically affects the speed.

Btw, can someone with this issue check what is the AHCI driver in their Device Manager under IDE ATA/ATAPI controller? I had Intel AHCI drivers installed (it’s was automatically installed with mobo drivers), replaced it with Microsoft default AHCI driver supplied with Windows (via update driver -> choose from this PC -> Microsoft AHCI driver) and so far so good. Tho now my USB mouse lags a bit when data is getting written too fast to the drive - but no errors in event log anymore and no disconnects. If someone able to confirm it with me, then it’s definitely drivers I/O conflict.
