Moving iPhoto to external drive; have formatted external disk to Mac OS Extended (Journaled), moved the iPhoto library to external drive; when trying to change the library, the iPhoto file on new external is greyed out can't be selected.What went wrong?

Must have done something wrong..
1. formatted external disk to Mac OS Extended (Journaled) - required a partition, but that went fine. Entire new external disk was included in the partition formatted to Mac OS Extneded (journaled).
2. moved iPhoto library to new external disk
3. Holding Option key down, opened iPhoto
4. Choose library feature appeared, however when new library function option appeared and "choose library" selected, the iPhoto folder appearing in the new external drive was greyed out and not able to be selected. Therefore the default library remains the original iphoto library on the Mac.
I've moved the original iphoto library to the trash and then tried to start iPhoto. A message comes up that the iPhoto is in the trash and needs to be pulled out before iPhoto can start (clearly the new iphoto library on the external drive is not being seen.
Can anyone suggest where I went awry? Thanks!

Try trash the com.apple.iPhoto.plist file from the HD/Users/ Your Name / library / preferences folder.
(On 10.7 or later: Hold the option (or alt) key while clicking on the Go menu in Finder to access the User Library)
(Remember you'll need to reset your User options afterwards. These include minor settings like the window colour and so on. Note: If you've moved your library you'll need to point iPhoto at it again.)
What's the plist file?
For new users: Every application on your Mac has an accompanying plist file. It records certain User choices. For instance, in your favourite Word Processor it remembers your choice of Default Font, on your Web Browser is remembers things like your choice of Home Page. It even recalls what windows you had open last if your app allows you to pick up from where you left off last. The iPhoto plist file remembers things like the location of the Library, your choice of background colour, whether you are running a Referenced or Managed Library, what preferences you have for autosplitting events and so on. Trashing the plist file forces the app to generate a new one on the next launch, and this restores things to the Factory Defaults. Hence, if you've changed any of these things you'll need to reset them. If you haven't, then no bother. Trashing the plist file is Mac troubleshooting 101.
Then try select it again.

How to read data from PC format external disk, using Labview MAC

Hi folks,
For years I have not been able to read data files from a PC formatted (created) external disk, using Labview for Mac. More specifically:
- I have Labview 7.01 running on OS X 10.4.11 on a PowerBook G4
- I have a 500GB external USB/firewire disk that was formatted on a PC and has data files (custom format) that were created on the PC. I believe that C code actually creates the files, but Labview 7/PC opens the files and appends some info (I don't think the fact that C or Labview touches the files is actually relevant to this issue though).
- I can connect the 500 GB disk to my mac, and it will mount just fine and OS X can see all of the data files (and anything else on the disk).
- if I use my Labview app to open and read a data file it fails:
- open/create/replace.vi (with read-only access) shows a file dialog window that lets me navigate to any file on the external disk.
- but, the vi returns an error 7
- if I use OS X to copy the data file to my Mac disk, my Labview app works fine.
So, does anyone know if:
- I'm just doing something wrong in my Mac Labview app?
- Labview 7.x solves this problem?
- Labview 8/Mac solves this problem?
- OS X 10.5 solves this problem; with Labview 7 or 8; or does OS X 10.5 worsen the problem?
Thanks, in advance...

Hi kehander,
Thanks for the reply. I tried filling a constant path with the Mac-defined path to a data file on the USB disk (ie "DATA2:file1.dat"). This resulted in the same error message.
I then considered that maybe I was misinterpreting the LV error message, and that perhaps I was supposed to address the file using PC-notation (ie. "DATA2\file1.dat"), even though the app is running on a Mac. No joy with this, but I get a different error msg:
"Error 1430 occurred at Open File
Possible reason(s):
LabVIEW: The path is empty or relative. You must use an absolute path."
Can you share what your reasoning was for your suggestion... I'm not sure I understand why a constant path would produce different results?

How to connect an external disk to time capsule?

Hi,
I've just connected my new external disk 2TB to the time capsule device. However, it doesn't show in the disk tab in Airport express. Yes, of course the disk is on, it's hfs+journaled formatted and works fine when connected directly to my usb port on my MacBook Pro.
Any suggestion, please?
Thanks.

Unless this is a really new feature, Airport Express doesn't support external USB disks; only USB printers.
The Wireless-N Time Capsules and Airport Extremes support external USB disks.

How long to format external hard drive?

I'm planing to use a 750GB Western Digital myBook external drive as my backup drive for Time Machine. I am using Disk Utility to format the drive as a Mac OS External (Journaled) volume. The drive has been formating for nearly 10 hours now, which seems to be way too long. There is a message next to the progress bar which reads "newfs_hfs: /dev/rdisk2s1: partition size not a multiple of 4K." I thought I would close Disk Utility and retry, but I got a warning not to interrupt an operation in progress.
Should I force quit the Disk Utility, or should I wait it out a little longer? And, in layman's terms, what does the message mean?

Ok, I did a little research and discovered that WD drives have problems being formatted with Disk Utility. I downloaded and installed a program called MacDrive 7 (it has a 5 day free trial). It's a Windows program, so I booted into Windows and was able to format the WD myBook as a Mac OS volume. Took 40 seconds! Time Machine is backing up my system on the WD drive as I am typing this. Don't know if I'm allowed to post links, but a search of MacDrive will easily get you to the program. Hope this helps anyone else who has problems with the WD drives.

How to partition/format external drive?

Hi,
I bought a WD MyBook 320 GB external drive. It is by default formatted in fat32. However, fat32 has a ridiculous file size limitation! (<4GB)
I have 2 Macs, one windows and one linux boxes at home, one linux and one windows boxes at work. I want that all the machines has access to it. But maybe I can forget windows box. I need some advice, which one is better:
1. Format it as HFS+, forget windows, maybe I can use hfsutils for windows, and maybe I can access to it by this (is there anybody using hfsutils???)
2. Format 120 GB in HFS+, the rest fat32. I will use HFS partition just for full image of my mac's harddisks, and fat32 will be accessible to every computer.
Any suggestions?
Thanks...

You cannot format the drive with both Mac OS Extended and FAT32 partitions. If you need FAT32 you must format the entire drive FAT32. If you format the drive Mac OS Extended, then you will need software on the Window's PC that enables reading/writing Mac disks such as MacDrive.
To format the drive:
Extended Hard Drive Preparation
1. Open Disk Utility in the 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. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing (this does not apply to external drives.) Otherwise, click on the Partition tab in the DU main window.
3. Click on the Options button and select the GUID partition scheme then click on OK. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
If you prefer to format the entire drive as FAT32, then in Step 3 select the MBR partition scheme instead of GUID.
If you plan to use the external drive to backup your main hard drive then do that by cloning the main drive:
How to Clone Using Restore Option of Disk Utility
1. Select the destination drive on the Desktop and press COMMAND-I to open the Get Info window. At the bottom in the Ownership and Permissions section be sure the box labeled "Ignore Permissions on this Volume" is unchecked. Set Ownership and Permissions as follows: Owner=system with read/write; Group=admin with read/write; Other with read-only.
2. Open Disk Utility from the Utilities folder.
3. Select the backup or destination volume from the left side list.
4. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button.
5. Click on the Restore tab in the DU main window.
6. Select the backup or destination volume from the left side list and drag it to the Destination entry field.
7. Select the startup or source volume from the left side list and drag it to the Source entry field.
8. Double-check you got it right, then click on the Restore button.
For added precaution you can boot into safe mode before doing the clone.

How big of an external disk do I have to use to back up my mac mini using the time machine app?

I have a new Mac Mini, and I wanted to begin using time machine to back up my files. I tried to use an external hard drive that is used for our other machines (PCs) and it would not allow that hard drive to be used b/c it did not have a valid file structure. I did not know how to fix that, so I was going to buy another external hard drive to support backing up the Mac Mini with OSX10.8.1 and a 500GB hard drive. I saw somewhere that as lonmg as I had twice the RAM (4GB) it should be ok, but that seemed to be too small. I was considering buying a 500GB if necessary.
Does anyone know if I can use a small 8GB flash drive to support the backups or do I need a 500GB or similar external hard drive to backup the Mac Mini with time machine?
Thanks.

It is recommended that Time Machine has its Own Dedicated Hard Drive that is at least Twice the size of the Drive(s) you intend to Backup.

How can I format external hard drive for both Mac

Hi, I want to use my Seagate external Hard Drive 1 TB on both Mac & Windows. I go to know that FAT 32 supports both but it can not transfer more than 4 GB data at a time. Is there some better alternative? Please suggest.

As said above Use exFAT but do the formatting on a Windows PC as I have had problems of Windows seeing the drive when done on a Mac. Once done on a PC it was seen by both platforms.
Also if you are running XP on the PC you may need an update for XP to see and use exFAT drives. It may be included with XP SP3, i'm not sure, but Microsoft has an update for both XP SP2 and SP3 so that exFAT drives are usable.

How to password protect external disk

How to Format external drive previously formatted for NSLU2

Windows XP.
I've had two external hard drives connected to my NSLU2 for several years. Always worked properly. Nevery any problems accessing files from either drive. Now, I'd like to remove one external drive and no longer use it with the NSLU2 (Disk 1). I just want to use it as a "regular" external drive and connect it directly to my PC by USB. When I plug it into my PC, it is not visible in Windows Explorer. When I right click "My Computer" and select "Manage", I can see it in the "Disk Management" section, but there is no drive letter assigned to it. It has partitions. When I right click on any partition, the "Format" option is grayed out and cannot be selected. Also, the "Change Drive Letter..." option is grayed out and cannot be selected. How can I format this disk back to whatever it needs to be in order to use it as a regular external drive? NOTE: I do not need to keep any files on the drive. I've already transferred the files I need to another drive. Thanks!

Never mind. I figured it out. I downloaded a free utility for formatting large drives in FAT32. The utility ran a quick format in just a few seconds and then the drive became available in Windows Explorer where I can now perform a complete format or just use as-is.

Removing Password Protection From External Disk Attached to Time Capsule

I have an TV and when I try to watch a show it always says that "file format is not recognized." I am pretty sure it is because my computer gets disconnected from the external disk that all the media is on. This disk is attached to my time capsule. I wish I could make it so it would automatically reconnect with the disk after being disconnected, but I can't figure out how to make the external disk non password protected without making my network password protected also. Does that make sense? How do I make a disk so it is not password protected if it is on my password protected network? If my computer is on the network then I should be able to access discs without having to put in an additional password, no?

From the menu bar, select
 ▹ System Preferences ▹ Energy Saver ▹ Power Adapter
and uncheck the box labeled Put the hard disk(s) to sleep when possible, if it's checked.
If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Start up in Recovery mode and launch Disk Utility. Is the drive recognized?
Start up in Safe Mode and test.
Reset the NVRAM.
Reset the System Management Controller.
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.
