Hard drives appear on desktop, but are inaccessible

Hi.
I recently bought a 17' macbook pro 2.6. I previously had a g4 with four hard drives in it, so I took a couple of them out and put them in external cases. I also have a few external hard drives that were always externals (never in the g4).
The problem I have is that I cannot access one of the formerly internal hard drives. It appears in disk utility and I verified it and there was a minor repair needed (I forget what), so I used the repair function and nothing has changed. The drive icon appears on the desktop, but not under "devices" in the finder window. When I double click on the drive on the desktop, any open finder windows disappear for a few seconds, then reappear, but the drive does not open.
The same thing happens about half of the time with another external drive that was always an external drive. The strange thing is that, even if I can't open the drive, iTunes can access the music files and library on that drive. These drives work fine on my wife's macbook (2.16, running 10.4).
And as if that weren't strange enough, about half of the times that I select "documents" from the "places" menu in the finder window, the same thing happens (finder windows disappear for a few seconds and the documents folder doesn't open), yet I can access my documents folder through my home folder.
The other drive I pulled from my g4 is currently my time machine drive and has no similar problems. Two other external drives also have no problems.
Does this ring any bells?
Thanks,
Bruce

rebuild the directory with Disk Warrior ... works wonders

My new external hard drive appears in Finder, but none of the files stored on it show up in recent documents (today/yesterday/past week).

what format is the external drive? How is it connected?
The drive must be formatted Mac OS extended (journaled) - if it is try Back up your iPhoto library, Depress and hold the option (alt) and command keys and launch iPhoto - from the resulting first aid window repair permissions and if necessary rebuild your database
Note that multiple libraries is not necessary and is generally a bad idea.

Neither hard drives appear on desktop or sidebar or in a save window

My G5 Quad has two hard drives. Tiger is on one and Leopard is on the other. Everything seems to be functioning properly but the drives don't show on the desktop, in the side bars, in the Finder>GO, or in save windows whether I have started up in Leopard or Tiger. They do show up in Disk Utility and I have verified both drives. They also show up in System preferences, Startup Disk. I've also checked that show hard drives is checked in the Finder Preferences. Somewhere I found a buunch of commands to type into Terminal to fix it, but I'm afraid of trying, doing something I don't understand and besides I can't find the article again. Any suggestions?

go to finder, hit command-, (that's "comma"), go to the General tab, select "Hard Drives" tick box under "show these items on the desktop". Try unchecking the box, then control clicking (right click) on finder in the dock and selecting "relaunch". Then check the box again. Then control click on the desktop and select "Clean Up".
Are you using multiple displays?
Go into Displays preferences and change the resolution of your screen to something else... it may be that the icon just got "off the screen" somehow.
For a finder window sidebar:
open a new finder window.
while holding down the command key, click on the "Title" of the folder you are currently viewing. For example if I'm looking at my "Home" folder, I would click where it gives my user name (while holding command of course). Select the item ALL the way at the BOTTOM of the list (it should read the name of your computer, possibly "Bilbo's PowerMac G5", or some such.
:You should see a list of all the drives, optical media, and network volumes on your computer. Drag the icon of the Hard Drives you want +in the+ sidebar *to the* sidebar from the main/viewing portion of the window.
Hope this is what you were asking for...

My external hard drive appears in bootcamp but not on my mac partition

This is intriguing. I own a macbook pro and run osx 10.6.8
I recently bought a new 1 tb hard drive and partitioned it. (300G for time machine and another for 700G for random things). It was working fine until I tried logging onto my bootcamp partition. I couldn't edit any files (due to the format of the drive), so I decided to relog back onto my mac parititon. Now the disk is grayed out in disk utility, under a different name and a different format type. I can read the files on my windows partition, but I cannot even access the drive on my mac partition. This drive is rather big, and I have no idea how I would even begin bcking it up... ( i don't have any other drives this large..)
Any ideas?
Thanks in advance!!

You wrote: "It's definitely formatted for windows...I have Disk Warrior, but it doesn't see my drive "DiskWarrior only works on disks in Mac OS formats, e.g. "Mac OS Extended" (aka HFS Plus or HFS+), "Mac OS Extended (Journaled)." It won't fix disks in MS-DOS/FAT32 format.
There are PC-specific disk utilities, akin to DiskWarrior for Mac, so if you have a PC as well, a PC disk utility might help repair the directory corruption if run from a PC.
External drives, whether they're formatted for PCs or Macs, can be subject to the same causes of directory corruption discussed in See my "Data corruption and loss: causes and avoidance" FAQ. Some of those causes have nothing to do with hardware failure and many are preventable.

USB Hard Drives Mount via AEBS but are Empty/Blank

I just came home with a new AIrport Extreme Base Station, bought so I could access my USB hard drives anywhere in the house. Before setting out this morning I read on the AEBS product page that you could connect multiple drives or printers using a USB hub, so was quite pleased.
I got it home, plugged in the hub, connected the ethernet, and connected to the AEBS from my MacBook Pro. I configured it to share my EPSON printer and the two USB hard drives I use. They all show in the Airport Utility. Configured security, updated, and mounted my drives. And they do mount, both of them show under "shared" in Finder.
The only problem is: They are both BLANK. There are no folders or files showing on them whatsoever. I panicked and plugged them straight into my MBP, hoping the AEBS hadn't formatted them or something, but the files were there and okay. I plugged them back into the hub... And nothing.
I see lots of threads having to do with people who cannot mount their drives, but that's not my problem. They MOUNT fine, they just don't have any files on them. Can anyone help? If not, the AEBS goes back to the store.

UPDATE: I managed to gain access to my files by switching (within the AEBS settings) from user-based sharing to a simple drive password. Once I did that I was able to browse and use my USB hard drives over the airport.
However, I would like to use the account-based system, so I'm modifying my question and adding another.
1) Why can't I see my files on USB drives connected to the AEBS when I'm using user-based security?
2) When I change users on my MacBook Pro, the other users cannot access the drives connected to the AEBS. I've got one password set now, using drive security (and I also tried it using the AEBS password for security), but it only works on my account. On other accounts, the user is informed that the password is invalid, even though I know I'm typing it correctly.
Basically I either need to get the AEBS to share my drives, with files, using user-based security or convince it to allow other users in when I have drive or base station password security for the drives.
Any help... Much appreciated!

Seagate USB drives appear on desktop but can't be read or ejected.

I have two different Seagate 1TB USB drives, both formatted as Mac OS Extended (Journaled) using Disk Utilities that work fine on my early 2013 MacBook Pro running Mavericks but cause various issues on my late 2013 Mac Pro (also running Mavericks). The drives will show up when connected to the Mac Pro, but when I try to view the contents of the drives, nothing appears and I cannot eject them. Sometimes, I end up with a spinning beach ball in the Finder. I have run the hardware test on my Mac Pro and no issues were detected. I have also Verified and Repaired the disks using Disk Utilities on my Macbook Pro and no issues were detected for those operations.
I'm figuring this must be some sort of driver issue, but I don't understand why the drives operate fine when connected to my Macbook Pro running Mavericks but not the Mac Pro running Mavericks. I didn't install any drivers on the Macbook Pro to get them to work, they just work.

>> also Verified and Repaired the disks using Disk Utilities on MacBook Pro
... and why would they need to be repaired on the nMP:?
It sounds like there is an issue with the port you use and assume you used the same cable.
Q: Does the case have its own power brick adapter or one of those cheaper and smaller bus powered?
Seagate does have a Thunderbolt docking station which is very nice and convenient, and of course will cost more than a USB3
Generally I recommend avoiding vendor's cases.
Seems like we need more information about the drives and case and interface etc.

Where can I buy a larger hard drive for my late 2008, 15" macbook pro? From reviewing questions and answers on the support community it would appear that having Apple remove the old and install the new hard drive is recommended. But how/where?

Welcome to Apple Support Communities
You can install the new hard disk yourself if you want to. You just need a 2'5" SATA II hard drive, which is compatible with your MacBook Pro. You can buy one at OWC > http://eshop.macsales.com/shop/hard-drives/2.5-Notebook/ You can filter hard drives by computer, so press a "Click to view all...", choose your computer in the sidebar and it will give you the compatible hard drives.
There are different brands for the MacBook Pro. The most recommended are HGST and Seagate, which have good reputation. A 7200 rpm hard drive will give you extra performance

Zap the PRAM and Reset the SMC, then try again. If the problem remains, update to 10.6.8 and repeat.

Can't move files from my external hard drive to the desktop?

Hi folks, for some reason I am unable to copy files (irrespective of type) from my usb 2 external hard drive to my desktop. This is only a recent thing. Up until a few days ago I was able to transfer files back and forth without problem. Now it is only possible to move unto the harddrive and not the other way around. The harddrive is formatted in Mac OS Extended (journaled). I have tried running disk utility to repair the disc on both external and internal drives, and it advises me that no repairs were necessary. I have also checked the info and read and write is permitted and none of the files are locked. When I attempt drag a file off the harddrive to the desktop the cursor turns into a stop sign (circle with line through it). If I attempt to copy and paste, the file copies and then will not paste as "paste" does not appear in the contextual menu. I have had some limited success by dragging files off the external hard drive to the trash and then dragging then back out of trash unto the desktop. But this only seems to work sometimes?
It would be great if someone could suggest a reason and solution for this. Thank you in advance.
Jono

Sure sounds like permissions are goofed up somewhere. You weren't really clear about exactly what you had checked. Since you can copy TO the drive let's assume things are OK there. How about your Desktop folder? Did you check it with GetInfo to make sure you are the owner and have read and write permissions to the Desktop folder? I have seen these get messed up before.

HT4897 My Aliases are still on my iMac desktop but are no longer on my iPhone. All operating systems are the current offerings.

I have i-OS8 on the phone and Yosemite in the Cloud and when I did this I still have the original 5 Aliases on the desktop, sending and receiving but I can no longer do it from the iPhone. What Happened?
I can get my main mail account to work on the apple ID account and as a test I tried adding a new alias and that worked but all my old ones are not working.
One of the old aliases was pretty important to me, what can I do??

The only answer I have is not a pleasant one. Your photos are gone. There may be computer services that might be able to retrieve photos from a formatted drive (and they might not be able to retrieve the photos from the formatted drive). These services are usually quite expensive.
PSE has low res thumbnails. You could blow them up in the Organizer to single image view, and then do a screen capture to save these low-quality photos. You would have to do this one by one.
In the future, making backups is a very important step. If your burner isn't working, you need to get it fixed, or you need to get an external hard drive for backups. You are one of a large number of people who have written here that your photos are gone ... and for anyone else reading this far, don't let this happen to you.

I would like to use time Machine to back up to a network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it

I currently have a mini server (OSX10.8.5, server 2.2.2) that I am using Time Machine to back up 4 external drives that are connected to the server via firewire 800. I would like to use Time Machine to back up to a windows network SMB drive. I can see the drive on my desktop but it will not show in the time machine window to be able to select it for use.
Can this be done
Thanks for any and all help

The supported targets for Time Machine backups are local (direct-connected) disks, and network targets include Time Capsule, a disk hanging off the current-generation AirPort (though not earlier AirPort devices), and OS X Server systems.
The Time Machine storage is based on the HFS+ file system, so I would not expect TM to work with SMB file services.
While there are hacks to allow Time Machine to access network drives, I would not consider those to be reliable. Skim the forum and the 'net for related details, and for previous discussions of setting this up and the related issues that can arise.
Remember to test the recovery with whatever you decide to use; whole point of backups is the ability to restore the data, after all.
If you want to learn more about Time Machine, Pondini is an excellent resource.

Highlighted Hard Drive Icons on Desktop no longer open when dragging/copyin

I noticed this yesterday and I have no idea how to fix it - hope someone here might have a quick fix.
When I attempt to move files into my folders from the desktop, I used to simply drag the files over the icon of the hard drive I wished to place it, and the icon would highlight, and then open, and I could navigate to the folder I wanted and drop them, and all the windows would close.
Now when I attempt to move files off the desktop in this way, the hard drive icon will highlight, but won't' open the window automatically as it used to.
I've done a permission repair and that didn't help it.
Anyone know how to fix this?
Respectfully submitted,
Len

Thank you for your response. That was exactly the problem. I have no idea how it became switched off, since I'm the only one that uses the computer, but no matter.
Thanks for the help!

Hard Drive Slow (Spinning ball) - but there's hope!

Hi people
I could really use help with this annoying problem. Iv read previous threads but my problem seems to be unique to me (as always!!!).
My MacBook:
MacBook Pro - mid-2009 I believe. A1268, with 2.53ghz processor.
So the problem:
MacBook Pro read and write slow, with constant rainbow ball when ever doing anything slightly intense. E.g. Unzipping files. Copying files. Using final cut. Download files.
It's almost like the hard drive speed is fine but it hangs every so often. For example if I'm unzipping a 700MB zip file, it'll quickly go from 0% to 15% then it'll freeze for 30 seconds or so (with beach ball) then resume from 15-50% and hang again.
What iv tried:
I cloned my HD to a working one iv nicked from my unused windows laptop. I swapped my MacBook pros harddrive with the new clone, and startde it up. But it STILL HANGGED! If anything it was worse.
The unique bit:
While my original HD was out, I attached it'll my MacBook Pro via a sata to usb caddy. I booted into this harddrive by restarting my macbook and holding option key. And voila! The MacBook runs smooth!
So now I don't understand what it could be. It can't be te harddrive as it runs fine when connected via usb. What else could it be?
Thanks in advance! Any suggestions welcome!

Hi Grant
I took the 2nd harddrive out and put it in the caddy and it was fine. So that has indeed narrowed it down to something internal, either the cable or the SATA port on the motherboard.
Iv been looking on ebay to find a harddrive cable, but there seems to be some listed with a extra part, some listed with the infared diode. Not sure which one to get. Both part numbers are the same. iFixit shows type 2.
Type 1
http://www.ebay.co.uk/itm/OEM-Macbook-Pro-15-A1286-HDD-Hard-Drive-Cable-821-0812 -A-821-0989-A-821-1198-A-/111042391045?pt=AU_Components&hash=item19daa46c05
Type 2
http://www.ebay.co.uk/itm/HDD-Cable-f-Macbook-Pro-unibody-15-A1286-hard-drive-82 1-0812-A-SATA-Interface-/110965222159?pt=LH_DefaultDomain_0&hash=item19d60aeb0f& autorefresh=true
Also, has anyone bought these cables from china? Comes with warranty. Or is it best to buy from iFixit?
Thanks

Renaming Windows Hard drive on Mac Desktop

I need help with this one....
I've successfully partitioned my hard drive with bootcamp, but when I open up my mac, it has saved the windows hard drive on my desktop as "Unknown"....how can I change it ??? (i would like to name it Windows HD)
I have tried twice by redoing the whole bootcamp partitioning setup, but I couldn't find anywhere where I would be able to change the name....
Thanks for the help!

Do it in Windows. Although I hadn't renamed mine until I read your post, I wanted to see HOW to do it, and the only way I was able to was within Windows itself. So just boot into windows and change it using the process required for windows os.
Once in windows, all you should have to do is highlight the drive in question, then right click on it, scroll down to "Rename" and call it what you want. Once you do that, when you boot into OS X it will changed there as well. Hope this helps.
