The drive as a whole has worked before over USB-C as seen on the first attempt that led to a crash.Ĭould something have happened in that crash that meant it will no longer be seen over USB-C.The mac is detecting the enclosure over USB-C, just not the actual storage ("JMS583").The SSD, enclosure and format will work with my mac, as seen over USB-A.What I have gathered from my attempts is that… I unfortunately have no access to another USB-C laptop to check whether it's my laptop (I would not be surpised, Catalina and the MacbookPro 16" have been a real disappointment) and I would rather see if it can be solved without buying an additional enclosure/drive. I re-formatted it and successfully copied everything across. Eventually I connected it to my old Macbook Pro 13' via USB-C to USB-A and it appeared. I physically reset the drive in its enclosure, and it had no effect. I've tried repairing via terminal over USB-A and it's had no effect. All that would appear in System Information was the enclosure with the name 'JMS583'. If I connect to a USB-C port on the HyperDriveNet (USB-C to USB-C) it does not appear. However, the drive still refuses to appear on my new laptop over USB-C, it only appears when connected to a USB-A port on my HyperDriveNet (which then converts to USB-C). Eventually I connected it to my old Macbook Pro 13" via USB-C to USB-A and it appeared. I physically reset the drive in it's enclosure, and it had no effect. All that would appear in System Information was the enclosure with the name "JMS583". It was frozen for a while and eventually the entire Mac crashed.Īfter a restart, the new SSD (NVMe) would not appear, not in Disk Utility, Terminal or System Information. I cancelled the transfer, and the finder bar froze on "stopping". I began to do a straight copy from another SSD (Sata), both connected via USB-C, the transfer was working fine, then froze.

I recently bought a 2TB SSD hard drive, placed it in a USB 3.1 enclosure and formatted it to Mac OS Extended (Encrypted).
