External Hard Drive Not Showing Up

Yay this totally worked thank you !!!

My problem is slightly different.
I can see my external Seagate drive on the desktop,
but only half of the files show up.
These are only the new files.
I know there are older pictures and videos on the disk.

It also says that it is still full of data.

What gives? I want to see my old pictures.

I have already verified and repaired the disk, but nothing seemed to be wrong.

Can you please specify what you mean by successfully "mounting" the external hard drive with these terminal commands?

I can see my ext.hard drive recognised on Disk Utility and also when I typed in these "mount" commands in terminal, it showed up.

But the final result I want to get is to browse my ext. hard drive in Finder so that I can back up my data.

Since I don't know much about Terminal, do you mean that I can achieve "that final result" simply by mounting the ext. hard drive in Terminal?

I can see my ext.hard drive recognised in Disk Utility but the "verify/repair the disk" button is not activated. I don't know why?

Also, unlike what SanCarlosDad explained, there is no indented gray drive name showing under the ext. hard drive in Disk Utility.

It seems like the only option activated in Disk Utility for my hard drive is to reformat it.

Could it be a key to explain my problem further? Anyone? Can you help me please?

FYI, I already tried to change the view options in Finder to show "hard disk" and "external drive" as well as "Devices."

I don't think my problem is related to the "viewing" dimension.

I'm not planning to simply format my hard disk either because this is my only back up drive unfortunately.

I am having similar problems and before I go ahead with something I want some feedback.

Having similar problem with an Old External (Details listed in Screenshot). One drive is grayed out, the other works fine. I want to attempt Picture2 since none of the other opinions listed in this thread have worked.

I want to know the repercussions of this act. I portioned the news drive space labeled 'Iomega Backup' on the drive (750 GB vs 500). And it is my understanding that DU will copy the non showing up 'Jeremy's Stuff' into Iomega Backup and then erase the contest of ST350082.

Anything I should know about this before moving ahead?

I tried all of the above, including shutting down mac and drive.

Finally, did it again, but this time I unplugged the power cord.

Waited 5 minutes, plugged it back in and rebooted and VIOLA.

Thank you!

Hi there,

I too have this problem. I upgraded to Yosemite to see if it might help but it didn't (I'm on a Macbook Pro). The drive (a WD passport essential) is showing up in Disk Utility but not in Devices...strangely I am still able to use it as I had a brain wave and searched for files I knew were on there and I could use them no problem.

I have done as suggested in the origonal post (using Script Editor) and did a Terminal bash (the ls -laeO@ /Volumes one) and the drive was on there...but it didn't work. I have also tried shutting down etc. Can anyone help?

thanks

A slight variation of this worked for me as well. Thank you for sharing your results.

Maybe you can help me too. I got this response

I had a problem where my external hard drive wasn't showing on the desktop or in disk utility.

- Tried it on a different mac, didn't show up in either desktop / disk utility.

- Other hard drives worked fine.

- Tried it with different cable, usb port, no go.

- Tried restarting, no go.

- Tried manually turning off computer, leaving off for awhile. Turn back on it works!

Weird, but happy about it.

hello,

I am having the same problem as it is not showing up on devices but it is showing up in disk utility.

I can not go any further as all the buttons in first aid are in grey and it will not let me mount.

Please help!

It worked for me too. Kind of same thing. The hdd was not showing up in finder but was showing up in the disk utility. So, i just kept it connected for some time and went to do my work. When I came back to my mac, I could see the hdd icon on my desktop. I could access it. I quickly copied my data and formatted it. Then I plugged it out and again back in to see if it shows up immediately and it did.

Now works pefrect.

I found if you go to disk utility and it is not appearing in the finder window, click crete a new image (once you make sure if it is formatted in the style Mac reads, Mac ... Journal Extended) and it should pop up

After all of the nonsense, application downloading, errors mounting and verifying/repairing...hours spent trying to restart my computer, redo my time machine backup, etc....all i had to do to make it work was to delete the finder plist file! After i did that, it seemed to actually make my computer run faster too. Before it was running some kernel task that wasn't anything significant but using 700% of my processor! So i wasn't able to do ANYTHING. Seems like this fixed not only the lack of drive usage, but also an even bigger issue.

We will see how long this lasts for. I cannot say for sure what created the issue to begin with, nor can i say for sure that this fixed it, but for now it is all clear!

😮
