I have a Pegasus 2 R8 that I am trying to get data from.  It disconnects consistently and has very slow copying that eventually bombs out - randomly reboots the whole machine. 

 

  • Started with a Mac Mini M1 - had Sonoma as the OS - I was able to copy from it and write data to it without any problem.  I updated the OS to Sequoia and that is when the problems started. 
  • I updated the firmware to the most current. 
  • I installed the Mac Silicon driver
  • I uninstalled the Mac Silicon driver and installed the standard Dext Driver.  
  • I have gone back to the previous OS Sonoma and used the Promise Utility to make sure that the device or raid array didn't have any issues.  (unit passes all tests)
  • I bought an old mac mini (intel chip) with monterey on it thinking I can use the old driver - but no luck.  

Here is my question - what am I missing.  Is there a utility that can tell me what is wrong.  Can anybody advise?

 

Is the firmware causing the problem? Is there a firmware I should use for Monterey.  Or is there a specific version of Mac Os and firmware combo that is the perfect set.
