WD External Hard Drive won't open due to insufficient access privileges

Hi all
So I'm getting this message"The folder "O-Drive" could not be opened because you do not have sufficient access privileges".
I received this drive from a client I'm doing audio work for and I've tried it on two different macs and have gotten the same message. Shows up on my desktop but not in the finder viewer and the disk utility can't access anything either. Any tips, ideas or solutions for this issue?
Thanks in advance,
joel

Iphoto from external hard drive won't open on another macbook

My iphoto wont open from my external hard drive on my other MacBook. It says: The photo library will need to be upgraded to work with this version of iphoto. Your photo library will not be readable by previous versions of iphoto after the upgrade.
1) Why do I need to upgrade?
2) Will I still be able to open this external HD on my old macbook?
When I click upgrade it says: there is a problem accessing one or more files in your iphoto library. Do you want iphoto to repair permissions for this library for you?
3) What does this mean?
4)Can I open this external hard drive iphoto library on a Dell laptop or will it always have to be on a Mac?
Thank you for your help!

You do not give enough information to give a total answer - but basically it sounds like you have two Macs with different version of iPhoto - newer version of iphoto have to upgrade the iPhoto library to use it and once they do older versions can not use it - that is the meaning of the warning
The photo library will need to be upgraded to work with this version of iphoto. Your photo library will not be readable by previous versions of iphoto after the upgrade.
Pretty clearly stated by the warning
so
1 - because you probably have a newer version of iPhoto on your "other MacBook"
2 - Probably not
3 - you have a permissions problem that needs to be repaired - often this is caused by having the iPhoto library on an improperly formatted drive - the iPhoto library must always be on a volume formatted Mac OS extended (journaled) - what format is the drive the iPhoto library is on?
4 - no - if the drive is properly formatted the Dell can not open it and if it can it has no idea what to do with it - the iPhoto library must be used by iphoto on a Mac - if you want to have your photo on a PC you have to export them to a drive the PC can read

Older iphoto on external hard drive won't open in Mavericks os

I have my iphoto on an external hard drive that I would open on two different computers. I recently upgraded my imac to Mavericks and now I can't open the library stored on the external HD; it's indetectible. When I click iphoto icon on the imac, the existing (internal hard drive) library opens. I *believe* before the upgrade I had to choose which library to open, but it was such an intuitive process I can't remember exactly what or if I had to do anything specific now. The library still functions fine on my macbook air, which is running iphoto 9.2.3.
Can I upgrade the iphoto on the external hard drive?? I've been reading tons of threads but haven't found a solution that sounds like it fits my issue. and of course i'm hesitant to just try anything as I don't want to lose all the photos (and I like how they're organized).
Thanks for any advice!

So can i update the library on the external HD so that it can be used with 9.5.1??
Probably - I'm still not totally clear on what you ahe, what you have done and what yu are doing
this statement is worrysome and more information is certainly needed
I recently upgraded my imac to Mavericks and now I can't open the library stored on the external HD; it's indetectible.
and
If I update the MBA to Mavericks with the EHD attached will the iphoto be updated to 9.5.1??
If you also update iPhtoo to version 9.5.1 on the MBA then both computers can access the 9.5.1 iPHoto library while the EHD is connected to them

External Hard Drive Won't Mount- Need to recover files

Hello Everyone,
I am hoping that one of you fine mac experts may be able to assist ~
Problem: External Seagate FreeAgent Desktop USB external hard drive
won't mount on desktop=ie: no access to my important files.. Please Help!
Details:
External seagate freeagent 500 GB Desktop USB HD ( only 2 months old)
(using for document / file backup-not as a startup disc)
on my Mac G3 350 MZ Blue & White Tower /768 ram/ running OSX 10.1.5 & OS9.2~
~
Problem: Started using the external 500 GB HD 2 months ago -with no problems-until this morning. Tried to double click to open it to access files
and got the "beach ball of death" and needed to restart.
My trusty G3 started up fine, however, the external HD was now
not showing up on the desktop as normal. I troubleshooted -by restarting,
trying different a/c plugs/ different USB ports , ran disk utility..called
seagate -not much help . Seagate said to try the HD on another mac-which I did-
a G5 tower- same problem.
~
The External hard drive will show up in disk utility, but is grayed out.
and when click "mount" same two messages keep showing:
message 1: "a disk attempting to mount as unknown has failed verification or has failed to
mount.please use disk utility to check the disk"
~
message 2- when unplugging and repluggin the usb in-and upon
restart:" you have inserted a disk containg no volumes that mac osx
can read to use unreadable volumes,click initialize to continue with the disk inserted ,click continue"
~
( I really need access to these files- and do not want to re-initialize the HD!!)
I ran Disk Utility /first aid "verify & repair , the following info came up:
Repairing disk "main backup 2007 ".
Checking HFS Plus volume.
Checking Extents Overflow file.
Checking Catalog file.
Invalid key length ( <<<IN RED )
Repair completed. "
~~
Though it said the repair was completed, the "invalid key length" issue
still comes up when re-running disk utility...Hard drive would still not
mount on desktop-even after restarting .
~~~~~
If there is a mac genius out there that can help?- it would be greatly
appreciated. I have tried to call seagate several times in the last several hours-
1st time-they disconnected me after being on hold 10 minutes-2nd call
I was put on hold for 40 minutes ..Finally spoke to someone ( they are not mac users or mac experts!)and he said I would need to send it to Seagate's Data Recovery-... for a fee of course!
~~~
At this point, I am hoping to just get the files and photos off
the hard drive- I heard about Disk Warrior-should I use that and if so
what version?
Thank you very much!

Will zapping the PRAM be of any use in getting the external to mount on the desktop?
Your external Hard drive is already recognized. But it cannot be mounted on the desktop due to its directory damage. You can certainly Zap the PRAM, and it will not hurt anything, but I am skeptical that it will change the situation.
Do you think the Disk Warrior 4.0 cd will even work on my G3 350MHZ running Mac OS 10.1.5?
If you boot from the CD and run it from the CD, absolutely yes. If you attempt to INSTALL it from a download or a CD, probably not.
Have you ever used Disc Warrior and is using it complicated?
I own and use Disk Warrior. You select the drive to be rebuilt, it builds a proposed new directory from the information and file fragments available.
When complete, it will provide a list of problems encountered, tell you what files have been placed in the "Rescued Items" folder, and allow you too look at your drive using the proposed new directory. Your only decision is whether the new directory seems to be an improvement over the old \[in your case, hopelessly corrupted] directory. You then tell it whether to replace the old directory with the proposed new directory, or to abandon its work and leave your Hard Drive unchanged.
Is there a good chance that the ext HD will still have my files on it- or do you think from what I've described that they are gone ?
From what you have described, your files are very likely to still be there. Sometimes in a situation like this, a handful of files cannot be recovered.
My other thought was to take the external HD there and have them try to recover the files.
Make sure you completely understand the costs involved. File recovery using a service like DriveSavers can run into many hundreds of dollars. They are prepared to disassemble your drive in a clean room and replace controller boards and read/write heads to achieve success. Your drive has serious, but not fatal, Directory damage. The Hardware, and most of your files, are likely just fine.

External hard drive won't mount, even after disk repair.

My Toshiba external hard drive won't mount on my MacBook Pro 10.8.5. I can see it in my disk repair, and when I repair, "the partition map appears to be ok." But I can't access the icon to be able to open the hard drive contents on my desktop. Help!

Hello maccynicwhoalwayshasmacs,
Thanks for the question. After reviewing your post, it sounds like trouble with an external HD mounting. I would recommend that you read this article, it may be able to help you resolve or isolate the issue.

After installing snow leopard my external hard drive won't show up on screen or backup

External hard drive won't unmount for disk utility.

Im not sure if this is the right topic area but I have a white macbook and my external hard drive won't unmount. I want to erase it via disk utility but it keeps telling me other programs are using it.

Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

My external hard drive will not open and only shows up in Disk Utilities. When I try yo repair it, it give me and error of invalid sibling link. How do I fix my external hard drive?

Invalid sibling link may not be fixable by Disk Utility. (Disk Utility is very conservative, and will not attempt repairs that might cause you to lose data.)
It is an indication of serious Directory damage.
that leaves
a) third-party Utilities that will take those risks, or
b) re-initializing the drive (which deletes all your data) and restoring from another backup source.
c) "Copying off whatever files you can salvage" has gone by, and you cannot copy anything off a drive that will not mount. You may be able to use "rescue" programs such as prosoft engineering Data Rescue to copy files to another drive, but that sounds a lot better than its reality. You may get many files, but not get ANY filenames.

External hard drive won't shut down after switch from OS10.5 to OS10.4.11

i recently chanded my OS from 10.5 to 10.4.11 (as a programme i want to use is not compatible with leopard), but since i have done this my external hard-drive won't shut down automatically when i shut down my mac. i have to switch it off at the plug instead.
can anyone suggest how i can get it to do this again?
i'm a little concerned that i'm damaging the external drive by turning it off manually all the time..
thanks

Some hard drives shut off with shutdown, some don't. Sometimes hard drives that did shut off with one system will not do the same with a different system. My hard drives which did shut off, prior to 10.5 now stay on.
This is not really a problem as all hard drives spin down after 10- 20 minutes when not in use, whether your computer is on or off. Leaving the drive on is fine, shutting it off manually is fine.

Do you also connect the external USB drive to the AC power as well while you use it ?
Sometimes USB external drive problems are resolved simply by plugging them into the mains power and trying again.

If I move the oldest 2/3 of my iPhoto library to an external hard drive, will I still be able to access those older photos? I assume that I will be able to select the source (internal hard drive or external hard drive)?

Yes, if you have a second library.
Here's one way to do what you want:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
Now you have two full versions of the Library.
3. On the Internal library, trash the Events you don't want there
Now you have a full copy of the Library on the External and a smaller subset on the Internal
Some Notes:
As a general rule: when deleting photos do them in batches of about 100 at a time. iPhoto can baulk at trashing large numbers at one go.
You can choose which Library to open: Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
You can keep the Library on the external updated with new imports using iPhoto Library Manager

If the drive can be accessed in local lan, then it can be accessed from internet assuming you have setup using one of the remote access methods.

External Hard Drive won't mount on desktop!

Hey, guys.
I ran into a problem this morning that I've never ran into before and I wasn't sure where to write it but I thought this is best.
Here it goes...
Last night I had a power surge and when I restarted my computer, my external hard drive did not mount on my desktop. I than proceeded with restarting my computer, I relinked all my connections and I cant seem to get it fixed. I have a lot of material on my external drive that I dont have backed up (I know, a stupid move) anyways, I dont want to lose that information. Also, when I open up disk utility, the icon for my external drive is there and the partition I made for my external drive shows up also but the title of my partition for my external hard drive is not in bolded font. I tried to click the button to mount my external drive cause the specs tell me that it is not mounted but when I press the mount button, it does nothing. I than tried clicking the unmount button and than restart my computer and still nothing.
What problem am I facing and how can it be fixed?
Thanks.

Dear Jason,
Gary's advised is, IMHO, a very sound one.
The only thing I can think of about your problem, given the information you have provided us, is to run Disk Warrior on your external HD.
In fact, DW is particularly indicated in events, like:
"...you should run DiskWarrior when you suspect that there is directory damage on one of your disks. Directory damage can result in the disk not mounting (not appearing on the desktop when the computer is started), missing files or folders, an inability to move or copy files, or crashes when files are used...".
You could actually buy your copy of DW Licence on-line and download it directly onto your internal HD, starting from this "Information you must read before you make your purchase" page. A hardware copy of the software you have so purchased, will follow by postal service (or currier, if so you choose), shortly.
Follow all the instructions you will find in the download to install the DW software onto your main internal HD and then run it on your external hard drive.
DW has saved my data several times and in similar situations as you are experiencing. IMHO, you should seriously give it a try and, even in the unfortunate event it does not manage to solve your problem, it is one of those Mac OSX utilities which ANY Mac power user MUST have handy at all times.
So, no matter what, my opinion is that it is always well-spent-money those used to purchase your copy of DW: in the long run, you won't regret it.
In the event that even DW is unable to retrive your precious data, my suggestion is to contact Micro Com data recovery. It's going to cost you some money, but if you make a leaving out of the data you've lost on your external hard drive, it's going to be worth it.
All the best.
Costa

My external Hard Drive won't transfer files to Mac HD and causes Finder to crash

My external Hard Drive (Western Digital 2TB hard drive in a ICYBOX 2-bay USB 2.0 HD Dock) won't transfer files to the Mac HD. The transfer box comes up but stays at the 'estimating time' stage and remains like that. No matter how big the file/group of files are (biggest I've tried was only 500-odd MB) it won't transfer and stays at the 'estimating time' stage. When I try and stop the transfer, the transfer box remains at the 'stopping' stage until I restart the iMac. I can access other programs during this 'stopping' stage, as long as it doesn't involve the External HD.
When I attempt to open files from the External HD in Photoshop CS4, both Photoshop and Finder stop responding and have I have to 'Force Quit'. However, upon force quitting finder, I loose all icons on the desktop until I restart the Mac via holding down the 'Power' button on the back.
Ive looked at a few forums already and done a couple things they suggested to similar topics.
- I excluded the Ext HD on the Spotlight>Privacy tab.
- I verified the Ext HD via System Utilities. Some errors came up but the Repair was successful and subsequent Verifications have returned as 'OK'.
- I tried the Mac Diagnostic tool as suggested by Apple, but when I press the 'D' key on start up nothing happens.
The annoying thing is that this problem came out of the blue, the Ext HD was working fine 3 days ago.
My system:
iMac 21.5inch, mid 2010
3.6GHz Intel Core i5
8GB 1333 MHz DDR3
OS X 10.9.5 (13F34)
The Ext HD:
Western Digital 2TB
Mac OS Extended (Journalised)
1.91TB available on the HD
Shares a 2 Bay ICYBOX dock with another 2TB WD HD
Connected to the iMac via USB 2.0 to a 4-port USB 2.0 hub
Any help suggestions would be greatly appreciated.
Cheers,
Tom

WD EHDs have an extremely high failure rate so don't be shocked if it is failing. However what you can do first is reset the SMC and PRAM first on the computer, do the SMC reset 2-3 times, sometimes the first try does not work. If this does not work then using another computer move the files to another EHD, this time buy a high quality HD, something like one of these

External Hard Drive Won't Mount in 10.2.8

Greetings,
I have a MacBook Pro running the latest version of Tiger. I have a Maxtor 300 GB external hard drive (Mac OS Extended [journaled] ) which I use with my MacBook to store music, video, other media, and backups. I connect that drive to my MacBook via FireWire, normally, but the drive can also do USB.
Since wireless connectivity is so nice, I thought it would be nice to be able to access that hard drive from anywhere in my apartment, without being tethered to the drive by a FireWire cable.
Enter my wife's iBook G3 and Mac OS 10.2.8.
She has this computer from her school where she teaches. It has a G3 processor running at 600 mhz with 128 mb of ram. Since she rarely uses the old machine, I wanted to use it to "serve" my external hard drive to my MacBook.
But when I connect the hard drive to the iBook via either USB or FireWire, it does not mount. I ran Disk Utility and the drive is visible in the pane on the left of the interface, but when I verify the disk I get lots of error messages that say, "Reserved fields in the catalog record have incorrect data."
I don't want to let the iBook repair the disk because I am afraid it my screw the whole thing up and I would lose all my data...not a good proposition.
So, my question: What is going on here? Is this drive simply not going to work with 10.2.8?
I wish I could upgrade the machine to Tiger, but it does not have the minimum system requirements!
Thank you very much for your help. I apologize if I missed something else in the forums that addressed this same issue.
Macbook Pro 2.0 Ghz Intel Core Duo 1 GB Ram 15.4" LCD Mac OS X (10.4.7)

All you need to upgrade the iBook for Tiger is another 128 MBs of RAM. It has both Firewire and USB ports. You do want to upgrade it for what you plan to do. The problem you may continue to have, however, may be due to the fact that the age of the computer is such the disk controller does not support hard drive volumes larger than 128 GBs, which is probably the reason the drive won't mount.
The reason you get DU errors is likely because the drive was formatted using the Intel Tiger version of DU, while you were using the Jaguar version. That's a definite no-no.
