Hi ,
I have been using Promise Pegasus2 R6 on an iMac for 2 years. Recently I disconnected it from the iMac and connected it to my MacBookPro. Here came the problem. I can not write on it. I can only read. Then I downloaded utility application from this website and had it rebuild, but the problem still cannot be fixed. Then connected it back to the iMac which it used to connect. It still cannot be written. I am using El Capitan. And I am 100% sure that it is formatted as Mac OS Extended. I have also tried to repair the permission of it, but to avail. It cannot be reformatted because there is over 2T data saved on it.
Thank you very much for your help
Michael
