I've also seen FireWire ports go horribly bad too. If the Mac drive reads fine, then get your data and get a new case.ģ) One final option not consuidered: If the case works, and the Mac HD works, your USB port may be dead on the mac - it happens. IF you cannot get the drive to work at that point you will obviously NOT need software to read it, and you will NOT need a new case because the external case was used for your Mac Drive anyway. It will come in handy for windows and mac recovery tasks. Failing that (iMac?), go for the external USB-to-IDE connector. If the case does not work, then the Drive may be OK!Ģ) Hook the problem drive to the mac's internals first! If ths Mac is a desktop machine, try hooking it up internally via IDE. If the spare HD works, then you've ruled out the case as benig the issue. As well check to see if the case hardware shows up in the System Profiler - usually in the USB section.
As one last try, you need to go into the Mac's Disk Utility, and see if the drive hardware is detected but the drive not mounted. If the new HD does not spin up and the drive is not detected then you could claim the case it at fault. Since most external hard drives are formatted for PCs, before the backup. Connect that case with the new HD to the mac in question. how to force mount an external hard drive mac This will load up OS X Recovery. Put a spare blank HD into the problem enclosure. MAKE SURE it's a truly an issue with the case before you go either route.
