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?

:-/ 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

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.

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.

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?

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.

Hard drive disappears and Disk Utility is not finding it

I woke my computer up from sleep this morning, launched Final Cut Pro and it threw me an error. It said there was a permissions error for one of the volumes FCP was using, then my hard drive disappeared.
It does not show up in Disk Utility, nor does it appear in System Profiler.
I took the SATA drive out of my Mac Pro and tried to mount it using an external SATA to USB dock. It spins and sounds ok, but still won't mount.
Anything I can do to revive this drive?

all of this pretty clearly indicates that the drive is dead. get a new one.

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.

My Firewire drive isnt mounting - can be seen in the disk utility but not mounting.

I have an older MicroNet 500GB Harddrive that has always been picky about what cables it uses. I used it not that long ago to download a mass amout of files to transfer from one computer to another and it mounted no problem. My iMac is newer bought it last year and has the 800 FW port and the Mirconet has a 400 FW and 2 800 FW ports.
I have tried multiple cables 800 to 800, 400 to 800, etc. I can see the drive in my Disk Utility and have run the first aid protocols to no avail. It refuses to mount to my computers...
Any one have any advice before I spend $200-300 to extract the data at Best Buy.
Thanks so much for any advice.

Was the external hard drive connected to a Mac or PC, when you transferred the large amount of files to it? I'm wondering if it has a corrupted directory, and needs a third-party product like DiskWarrior (which is better than Disk First Aid) to straighten it out. It's possible that the FireWire bridge board in the external case is bad (which could explain its hypersensitivity to cables used). I wouldn't pay $200-$300 for data retrieval, before exhausting less expensive options, assuming that the drive's warranty has expired. Examine the case to see how it's held together - often the cover sleeve is secured to the rear plate with small screws that can be removed. Sometimes, one screw is covered with warranty-void tape, which can be peeled back/off. If it's a plastic case, you may run into problems. Some plastic cases have hidden snap latches, that require a special tool to release without breaking them. If you can remove the case's cover, you can access the bare drive. Remove its mounting screws (either on the side or bottom of the drive) and disconnect the data and power cables. With the drive removed, you can use an adapter like this one, which will adapt the IDE or SATA interface of the drive (whichever it has) for connection to a USB 2 port on your computer. This is a generic piece of hardware - you don't need to buy one marketed for use with Macs. If the drive doesn't have a mechanical and/or electronic problem, it should mount on the desktop.

External hard drive suddenly became "unreadable" and the disk utility offers not repair options. The drive is visible in disk utility but may not be mounted... any suggestions?

I have a WD My Passport 070A Media 2.0 TB external hard drive that has suddenly become unreadable on my laptop (MacBook Pro circa 2006 with 10.4.11) and I have tried on a MacBook Pro 2011 running 10.6.8 with the same results. I had tried opening disk utility to repair the drive, but on both machines the drive is visible in the left column, with no indentation below the drive. When I select the drive in the first aid portion the only options highlighted are info and eject... I was wondering if anyone had any suggestions to repair the drive. I am currently in Belize and am not home for 3 weeks yet. I'm hoping for a fix while I am down here, otherwise I may have to wait... I appreciate any assistance!

Hi Christina,
It's quite possible the AC PSU has given out, if It's only Bus powered as it appears, that's the worst idea ever & asking for eventual problems.
What Format is it?
Did you install any WD SW?
Your best bet is DiskWarrio...

But others that may work…

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.

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...

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:

2nd Hand iMac wont boot. Tried "repairing drive" in recoveryHD disk utility but doesn't fully pass through. HELP! :(

I have just purchased a second hand mac from Gumtree as Im eager to get into the beauty that is OS X.
But when I try and boot it will just stay at the apple logo with the spinning bar.
I booted into the recoveryHD with COMMAND+R and launched disk utility, I then proceeded to click "repair disk" on Macintosh HD.
It hangs for a while but then says "The volume Macintosh HD could not be verified completely" and then says ERROR:Disk utility cant repair this disk, backup as many of your files as possible, reformat the disk and restore your backed-up files.
I then tried to "re-install OS X Mavericks" but I need an apple ID with Mavericks purchased (please note I am on a windows machine and cant do this).
I've tried calling 133 622 but apparently their phones aren't on from 9am-9pm as stated (It's currently 7:30pm).
This is turning me off Macs as this sort of stuff should not just "happen" and due to apples "no windows support" views I cant actually do anything.

Mavericks is a free OS yes? If theres a way I can get it as a purchase on my Apple ID I can download and restore. I was just wondering whether there was a way to restore from the recoveryHD
And as for the no windows support, their OS X utilities image for USB is only available as a .dmg so I cant use that tool to recover from the recovery partition

My hardware RAID 1 only showing up in disk utility and not finder.

Last week I finally was able to take my early 2011 iMac in to have my Seagate 1TB hard drive replaced for the recall.
Late 2010 model iMac
OS X 10.6.8
OWC Mercury Elite Pro 4TB x 4TB Hardware RAID
When I took it in the RAID 1 was working just fine. When I finally got the iMac back and booted everything up the RAID 1 was getting the dialog box that read "The disk you inserted was not readable by this computer."
I have tried going into disk utility to see if I can verify the disk and then saw it is coming up as two different volumes... Along with those two different volumes, I can not go to click verify as it is greyed out.
I contacted OWC and they said they have never heard of this and had two solutions, to try a software like diskwarrior, or if that didnt work I can take the drives out and try another external dock to see if it is the RAID hardware.
If anyone has any ideas as to what could help with this situation that would be great as I was under the impression (and told by a number of other people) that having a RAID 1 as my backup was good and should not need anything else. I just want to be able to get all the data off then I will rebuild it or send it into OWC.
Thanks!!!!

So a fault in the Hardware Raid controller could make it not read properly? I am planning on having a good backup set up after this!
As for the screenshot, the original was not set up with the SoftRaid. When I got the computer back I installed that to see if that may pick it up and make it at least readable to save the data on it. The two in question are the highlighted 4TB drives, which befor also read as one drive as it was set up in the OWC enclosure as a hardware raid.
