I'm running MacOS Catalina 10.15.6. My Pegasus2 R4 drive was mounting fine for a while. Then it would eject if the system went to sleep. I updated the drivers and rebooted. Now it won't mount at all. I can't see it in the disk utility either.

When I go to my system information on the Thunderbolt device tree I get the following:

Pegasus2-R:

 

  Vendor Name: Promise Technology, Inc.

  Device Name: Pegasus2-R

  Vendor ID: 0x2

  Device ID: 0x9

  Device Revision: 0x3

  Speed: Up to 20 Gb/s x1

  Current Link Width: 0x2

  Port:

  Status: No device connected

  Link Status: 0x7

Anyone have any ideas?
