"Thermaltake 5G Duet" keeps disconnecting on Mac OS X, with the latest Yosemite.
â€œDisk Not Ejected Properlyâ€ is usual message. It happens suddenly with no special reason.
I might copy something or do nothing at all. It may take 2 minutes, it may take 10 minutes till disconnection.
HDD are 3 Samsung drives from 2008. Working fine in the PC.
Drives ar NTFS, and Mac OS Extended (Journaled)
I have tried:
- unchecking â€œput drives in sleep when possibleâ€ in Energy saving
- downloaded some wierd JMicron firmware update utility, which did nothing and is disabled on start, no matter do I add additional drives or leave enclosure empty.
- tried different drives in different combinations.
- read lots of forums on the internet about the problem, which is not unique for me, no help.
I am an IT professional, so your answer may get as technical as it needs to be.
Also, what similar product you would recommend, which worked on Mac OS, because I am about give up on this one?
