2009 iMac not recognizing external hard drive. My 2009 Mac Pro died power supply. It was cheaper for me to buy an older iMac. I removed the hard drive from my Mac pro and put it into an enclosure to use as an external drive. However it’s not showing up on the desktop or in disk utilities. I don’t want to wipe the drive because of the information on it I wish to transfer that to the iMac any suggestions?
You should be able to see the drive with that setup, if both the drive and enclosure are working.
I would recheck the drive connection inside of the enclosure and then the external connections.
Then if that doesn't work, I would try another drive enclosure, a drive dock or a SATA to USB drive adapter.
What model # is the KuWfi enclosure and how are you connecting it to the 2009 iMac?
(WiFI, Ethernet, USB)
Then Enclosure is from KUWFI.
The power supply was diagnosed by a Mac repair shop. I don’t have a backup drive because I could never get a second drive to initialize on that computer. That said I think the problem may be that iMac has an earlier version of software than my hard drive so I am updating its software now. I hope that works
At this point, I can only think of more questions.
What external drive enclosure are you using?
You sure the power supply died and not the hard drive?
Do you have a second internal or external backup drive for the Mac Pro?
No model number for the case. It has a separate power supply and hooked up via USB. However my hard drive external is formatted with 10.11.6 the iMac updated to 10.11 I don’t know if it can go any further
Not sure what is going on I did us OS X update and it updated to 10.11. Then I did a Camera update and it showed up as 10.11.6 but my hard drive still isn’t showing up. I made sure the enclosure was a USB 2
Even the instructions were laughable. But I took it out of the enclosure as you suggested and just plugged it into the front and to hook it up. And it’s working after a fashion. This hard drive is dying and that’s one reason why I wanted to get it working. I’m currently using migration manager to transfer files etc. to the iMac. It’s been a long day with this machine and I really thank you
I was just looking at the system report and realize that instead of a 2009 iMac the person shipped me a mid 2007 iMac. So this discussion I guess isn’t relative any more
Thank you
You're welcome.
I sure wish I had more info, on the drive enclosure you have.
(there has to be a model # or serial # somewhere on it)
That is good news, your welcome.
