Mac owner using a Promise Technology 32TB Pegasus2 R8 Thunderbolt 2 RAID Storage Array (7200 rpm). Since 2015 it has worked flawlessly.
I'm currently using a 2023 Mac mini. M2, 24GB memory, OS 13.3.
Today I noticed the Promise was painfully slow... investigated further and it started giving me "Bad Sector found on physical disk" alerts and the external light on one drive turned amber. It would still show up in my Finder but if I selected the Promise I would just get the beach ball of death.
I decided to plug it into my old iMac and the Promise seems just fine there. Using the Promise utility it confirms that there was a bad sector on one of the disks, but I can still use it as normal, and all the external lights are blue (normal). I'm currently backing up the really important files.
Why do you think that it seems fine with my old Mac? Do I have to go through the hassle of replacing that one drive or is there something I can do to my Mac mini? If I need to replace the drive will any 4TB/7200 rpm drive do? For instance: https://www.amazon.com/gp/product/B099P9ZXVG/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1
Thoughts appreciated. Thanks.
