IMac not detecting External Hard Drive thats been working!

August 4th, 2013

Hi, I have an iMac 21.5″
I bought another 1TB External Hard Drive for it as I was running out of space on my older External one…
Anyway, I got it, reformatted it to work on the iMac, everythings been good since I got it about a week/2 weeks ago…
I just turned the iMac on now and the External Hard Drive is not showing on the iMac, i’ve checked in Disk Utilities and it’s not showing there either,
i’ve gone into Finder – Preferences and made sure the External Hard Drive was ticked and so on…
I’ve unplugged it, both Power and USB, i’ve restarted the iMac but still nothing!
what can I do to get this working as I have alot of important files on it and im not sure why it just all of a sudden wont work when it hasn’t been moved and so on.

Answer #1
Do you have another computer to try it on?
Can you feel it spinning if you touch it?
Does the light turn on? (power led I mean)
FYI, An HDD can go bad any time, Even after two weeks, Keeping backup is very important, Most ppl don’t get this
however til it’s too late.
