External HD shows up in Disk Utility but not in Finder.

I can also see the HD in the drive's software, but I can't use it or access the data, since it's not in Finder. This is on my iMac (mid-2011)
When I plugged it in to a different Mac, I was able to see it in Finder.
Any suggestions are welcome--thank you!

It may just be hidden If you hover over the word Devices in the sidebar is there a show option?
You can try to go to it Finder > Go > Go to Folder > /Volumes/Volume Name (type first letter and tab)
Try Mounting it from Disk Utility
Maybe repair from disk utility
Try alternate USB ports or cables, try to connect through a hub.

Wd my book shows in disk utility but not in finder

can open the drive from within disk utility and a regular finder window will pop up. all data is intact. verify and repair show no issues. have checked finder preferences for showing external drives.

Do know the name of any file that is on the iso image? If so, do a Spotlight search on the file name and see if it show up. If it does, Command click on the result in the Spotlight list and see if the enclosing folder opens in Finder.

Hard Drive Reads in Disk Utility but not in Finder

I have a Seagate FreeAgent hard drive that is configured to NTFS. I use software to read and write to this on my macbook pro. I have plugged my hard drive into my macbook this morning and it will only read in Disk Utility, and not show up at all in Finder. I have plugged it into another macbook and have the same thing. Tried to do disk repair and it said it was repaired and operating normally, but still not opening in Finder. I also tried it on a Dell running XP and same thing, doesn't open as a folder but shows as operating normally in the XP's disk utility equivalent. I have tried finding an answer elsewhere but can't come up with anything. Besides taking it for data recovery, is there anything else I can do or try to fix without compromising the data?

You might get more help were you to post in something like the MacBook or OS X forum. This forum is for OS 9, an archived Apple Macintosh operating system.
That said, it sounds like your drive might be dead. When you say that you can see it in Disk Utility, you mean that it shows up in the column on the left? When you repair it, can you hear the drive spinning up?
Can you try making an image of the drive to see what happens?

Files show in Disk Utility, but NOT in Finder

Hi there, having trouble with my backup drive. It's a 1TB WD My Passport Ultra.
The drive mounts in Finder, but is extremely slow. In Disk Utility, the drive shows the correct disk space usage and number of files;
but in Finder it only shows the folders/files at the root level of the drive, and each has a size of zero bytes with no items:
What is happening? How can I access the data (it's obviously still there if DU shows the files) and (possibly) fix this?

Also, Finder displays the correct disk usage at the root level:

Drive visible in Disk Utility but not Finder. Why?

I have a PowerMac G4 (mirrored drive doors) with 4 hard drives installed. 3 of the drives are set-up in a striped RAID array and the other one is my boot drive with two partitions. One one partition, I have OS X 10.3 and I can see the RAID drive fine. On the other partition, I fresh installed 10.4 but the drive does not appear on the desktop. Strangly, I can see the drive in Disk Utility and it shows me the mount point. I can even unmount and remount it but it still does not show up in the Finder. I had 10.4 server installed prior to the fresh 10.4 (not server) install and that showed it fine. I tried to see the drive in Terminal but also does not appear. Why does my drive appear in Disk Utility but not the Finder?

BDAqua wrote:
Yes, it needs the path to the drive...
:-/ Yes, I got the command in completely with the path to the drive like it states in the other post. I have no idea why it didn't recognize the command as I'm not as familiar with UNIX/Linux commands as I'd like to be.
Anyways... I found the cause of the problem (incase it happens to anyone else). Here's what happened:
The ownership on the root of my RAID volume was set to be read/write for me (under my proper username) and no access for anyone else including Admin. When I installed a fresh OS, the default user was Admin (who had no access under the previous OS). If I would've taken the time to set-up my proper account (with the same owner name as my previous OS) then it would've been visible again but since I didn't see it under the default Admin account, I stopped there to troubleshoot. Another way to make it visible was just to change the access privileges from my previous OS to be read/write for other users (or at least Admin). I would think that checking the box for "Ignore ownership on this volume" would've remedied that but for whatever reason, it didn't.
Thank you for all your help. I did learn a little even if it wasn't the direct solution. Now if only I could get Disk Utility to restore my old image without giving me crazy errors... But that's another issue altogether. ;-D

I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out.

I have an external hard drive that shows up in disk utility but Verify and Restore are greyed out. I am trying to determine what is wrong with the drive.
I need the data on the drive and it won't show up in Disk Warrior. I have tried different Mac's and different USB cords only to find the same outcome. When selected in Disk Utility the information read as such...
Disk Description : WD Elements 1023 Media                      Total Capacity : 500.11 GB (500,105,740,288 Bytes)
Connection Bus : USB                                                               Write Status : Read/Write
Connection Type : External                                                     S.M.A.R.T. Status : Not Supported
USB Serial Number : 575837314135304D36373132        Partition Map Scheme : Unformatted
As the drive shows in Disk Utility there must be some life left in it surely. There is a possibilty that the physical connection between the USB cord and the external drive is damaged but since the drive shows up I believe it's unlikely... before I give it to the pro's is there anything else I can do to diagnose the issue?

Hello,
I have just experienced the same thing!
Although my external drive shows in Disk Utility, it does not show in Finder.
And the Verify/Repair buttons are also greyed out.
Also, although the drive is 2TB. DU shows it as having Total Capacity of only 4.14GB! (Which should be the Free Space).
I was wondering if you solved your problem, & if so, would you share your solution.
I´m afraid to Erase in case I lose all my Data on the drive.
Thanks in advance for your reply!

Hi, I have a freecom 1TB hard drive which was working fine until it froze. I pulled it out (mistake I now know) and now it doesn't mount. It shows up in Disk Utility but won't manually mount. When I try to repair it gives message 'failed on exit'. hel

You likely need to reformat the drive which will destroy all data and you need a backup to restore it. If no backup is present then a data retrieval service can be more expensive than DiskWarrior. There is software that can rescue the data but I can not vouch for it's effectiveness as I have always maintained backups. .

Lacie Hard Drive Appears In Disk Utility But Not Desktop

Hello,
My Lacie hard drive was working fine till yesterday. It will appear in the disk utility but not on the desktop? I'm using a G4 with mac os 10.3.9. I have tried disconnecting the power and rebooting to no avail.
Any help?
Thank you.

Welcome to the forum.
Have a look at the comments on THIS THREAD. Perhaps there's something there that will help.

External Hard Drive showing in Disk Utility - but not desktop.

A little background:
Yesterday, I moved my shelf where I have my modem, Airport Extreme, Airport Express and an external HD connected to the extreme to be a wireless HD for all users to access. Everything worked great - no problems whatsoever.
Problem: I have reconnected everything exactly as it was and reconfigured it as it was and now the external HD is having issues. When connected to the extreme, I can see it in the airport utility, but cannot gain access to it in that way. When I connect directly to my macbook, it is recognized by the disk utility, but does not appear on the desktop.
I don't know if this may have caused the problem, but I carelessly, unplugged the power bar for which all the above mentioned hardware plugs into when moving the shelf. Now, everything works as it did, except I can't get the express to show up once it is configured (but this isn't surprising as I had to fight with it the first time I configured it - not uncommon I am told), and the HD is no longer accessible via the network, or when directly connected to my macbook.
Help! According to the utilities, the data is still on the disk, I just can't access it in any way.

From the Disk Utility, select the drive and click on the Repair Disk(not Repair Permissions) button. If the Disk Utility finds a problem it can't fix, DiskWarrior or TechTool Pro will likely succeed.

External hard drive seen in Disk Utility, but will not mount.

My external hard drive has power and is spinning, but will not mount. It was fine yesterday. It shows up in Disk Utility and is verified and repaired. Tried the drive on 2 other macs with same result. Tried a new enclosure and that did not work. Tried all ports...usb and firewire. Any way to save my data?
I have screen shot of the partition info from Disk Utility for the hard drive included:

Hi Dominic,
If this is still not mounting, it may be worth trying a PRAM reset...

Mounted .iso file shows in Disk Utility, but inaccesible through finder

Hello.
I have an .iso file that used to mount flawlessly, but now when double clicked shows only in Disk Utility, while remaining inaccesible otherwise (finder hierarchy starting from computer should show all mounted drives, but this one is missing). Disk Utility doesn't find any errors. Is there any other way to find out what's wrong?
thanks

Do know the name of any file that is on the iso image? If so, do a Spotlight search on the file name and see if it show up. If it does, Command click on the result in the Spotlight list and see if the enclosing folder opens in Finder.

External HDD shows up on Macbook Pro but not on new iMac

I recently purchased a new 21.5" iMac and when setting it up, I utilized the Time Capsule backup from my Macbook Pro; everything seemingly went fine and my iMac was set up with all the data on the Time Capsule at the time (last update was a few months ago). Once everything was ready, I signed into the Mac App Store and downloaded the Yosemite upgrade (the iMac came with Mavericks). All the while, the Western Digital External HDD was not connected to the iMac.
Once everything was complete, the system rebooted and I was off and running with my new Mac.
The problem comes in when I tried to plug in the WD; everything lights up and it seems like the system is picking up the drive but then it just hangs there. It does not show up on the Desktop or the side panel in the Finder but it does show up in Disk Utility. When I verify the disk, it tells me that it is not mounted and when I try to mount it, it tells me that I cannot and to try to run First Aid on it. I have run a Repair disk and that made no difference.
The real head-scratcher is that the Macbook still picks it up without any issue but the new computer does not.
Can someone please help?
P.S.
The WD was never formatted for Mac since it worked on the Macbook right out of the box and now I have about 500+ GB worth of info on there that I would rather not lose.
Thank you.

It's something I can look into doing although I don't have a spare drive to copy all of that to and/or am not really looking into getting another HDD.
I am mostly wondering if anyone can provide an answer, or rather a reason, as to why it will legitimately work on one Mac (without any issue) and not on the other...especially if the new system has been set up using the information from the first one.

Hard drive visible in Disk Utility but not on desktop

I have an external hard drive, one of a RAID 1 mirrored pair which I have been connecting to my computer with FW800. I was having problems as was using one of them for a while, which solved them. When I hooked them both up to my computer, they showed up as two separate drives rather than one drive like before (since they were mirrored). Now the one I have been using does not appear on the desktop but I can see it in Disk Utility, but can't fix permissions with it or even verify it. I've tried connecting with USB instead of FW800 but that has no effect.

already checked, there is a problem with my computer or with the external hard drive. Now a new esata array is giving me problems so I am starting to think there is something wrong with the computer.

How do I access an external hard drive that shows up in Disk Utility but will not show up in finder or on my desktop?

I have an external hard drive that just stopped showing up one day. Is there a solution to this problem that allows me to secure the data on the drive before reformatting?

I'm having the same problem bpay14, but with a CalDigit VR2 6TB RAID0 external hard drive.
One day it was showing on my desktop, the other it wasn't. And I still didn't update my Mavericks to 10.9.3 (still with the 10.9.2).
It shows up in the disk utility, and I can even Verify the disk and Repair it (but I don't wanna start repairing
something that probably doesn't need to be repaired, so I haven't clicked the Repaid button, only the Verify button) and it says its working just fine.
But it doesn't show in the Finder or the desktop for that matter.
And even if I force disconnect the cable, I get the usual "this disk was not ejected properly" notification
presumingly the disk was mounted on the desktop and I forced eject by unppluging it...
I found a way to force open the disk, through Disk Utility that's by clicking with the right mouse button
on the disk icon, and chosing OPEN "CalDigit AFRICA 6TB"... (see picture 1)
But... after that, it open a Finder window showing all my internal and external drives, but that drive's
name is in washed grey, like if it was unmounted (see picture 2).
When selected, I can see everything and work normally on the harddrive, even opening FCPROX projects or Libraries, copying from it and writing documents into it... just normal... (see picture 3)
BUT IT DOES NOT SHOW IN THE DESKTOP...
that's my problem...
I even did a Command+i for Info on the hard drive. (see picture 4)
Can anyone shed some light on this issue?
I would be eternally grateful!
Thanks in advance!!!
Cheers!
