Beeping and not mounting

Postby matrixarchitect » April 17th, 2020, 8:11 am

Hi. I purchased a mediasonic enclosure (Mediasonic ProBox K32-SU3 3.5" SATA Hard Drive Enclosure - USB 3.0) from Amazon on 4/2015. Hard drive is a Seagate 2GB barricuda Green ST2000DL003. Running MacOS 10.14.6 Mojave on a 21.5 inch iMac from late 2013. I unplugged the iMac and put it away to paint the room its in. When I plugged it all back in the enclosure started to beep constantly and drive would not mount. It sounded like it had trouble spinning the drive. After a bit of turning on and off, it eventually mounted. Fast forward to today and the drive now just beeps and will not mount at all no matter what. Took drive out and put it into a thermaltake USB docking station and drive mounts. Seems to be an issue with the Mediasonic enclosure. Any help appreciated.

*Update - Tried a smaller laptop drive in the enclosure and that drive mounted just fine. Perplexed here.
