Been given a critical drive failure warning on our 16 TB Caldigit HD One RAID. Trouble is, the RAID Shield driver is no longer supported past OSX 10.9. The machine has been giving the three beep warning intermittently over the past year but now it is almost constant, and we've only found out that it was a drive integrity issue (...) Is there any other programme to figure out which driver has failed so we can replace it? Thank you.
If those are the original hard drives you should replace all the drives. When one fails, it's a very good indication that others will soon follow suit. And, with one drive dead on a RAID 5 enclosure and the others maybe ready to join it, your data is now extremely vulnerable - if you don't have a backup of everything on that RAID, you should do so immediately.
