I replaced a 500GB drive in my FW Drobo with a 1TB to add capacity. There were no issues before I pulled the drive apart from Drobo being quite full. However a while later I popped the drive into a USB caddy and it wouldn’t mount. I just tried it directly in my MacPro and Disk Utility doesn’t even see it.
Is this just a coincidence that the drive died after removing it from Drobo, or could the Drobo somehow be implicated in bricking the drive?
Any other way that I might ‘revive’ the drive so I can try reformatting it?
