External hard disk can't able to format

i had bought 1TB toshiba hard disk which says support mac also .But when i connect to mac book pro its not supporting and even i can't able to format. while format am getting error like "unable to write to the last blocked device". please help

If the problem is getting the drive to mount, there's really only one application that I know of that you could even try (and I've no experience with it) - DiskWarrior. A data recovery specialist could cost in the $800-1000 range. DiskWarrior is only $100 but there's no guarantee that it will work. Others, I know, have had some success with it - others have not.
But it's the only thing that I know of that even might be worthwhile. I've tried Data Rescue 3 with great success on drives that are not damaged. DiskWarrior is advertised to work with even damaged drives.
Good luck,

If I put my I tunes library in my external hard disk can I still share it with all the accounts of my Mac?

If I put my I tunes library in my external hard disk can I still share it with all the accounts of my Mac?

Hello there, Gnorra.
The following Knowledge Base article reviews how to share your music in iTunes with multiple users on the same computer:
iTunes: How to share music between different user accounts on a single computer
http://support.apple.com/kb/ht1203
If you're using Mac OS X, follow these steps:
Quit iTunes.
Go to your iTunes Media folder. By default, it's in ~/Music/iTunes. (This folder may be named iTunes Music if you created your iTunes library in iTunes 9 or earlier.)
Note: "~" represents your Home folder. Other users on your computer can't access these locations.
Drag the iTunes Media folder to a public location. For example, you could move it to the Public folder in your Home folder (~/Public) or to a location outside your Home folder that other users can access (/Users/Shared).
Important: Don't move the iTunes folder, the iTunes library file, or the iTunes library.xml file.
Open iTunes.
Choose iTunes > Preferences.
Click Advanced.
Click the Change button.
In the window that opens, go to your iTunes Media folder.
Click Choose or Open.
Repeat these steps for each user that you want to share music with. If multiple users on your computer are storing music in the same public folder, duplicate song files may appear if a user imports music from a CD that another user already imported.
Thanks for reaching out to Apple Support Communities.

One other option you might want to consider is exFat.
Its supported on Mac and Windows, and even my TV!
Its got very large file (128PB) and volume size support.
Cheers.
Not again.
The OP wants this to use with a PS3, which does not support exFat. So that suggestion (while quite correct on its face) won't work.
Maybe this will help you.
Check what the File System type is. Do this by going to Start, Control Panel, Administrative Tools, Computer Management, Disk Manager. Select the external drive and read the "File System" type. The file system type must be FAT32 in order for the PlayStation to recognize it.
Split larger, high quality files into smaller files, if necessary. FAT32 has a limit of 3.9 Gigabytes per file, which means some high quality HD movies might have to be split into smaller files, and that makes it less than ideal for some HD content.

Problem with Lightroom 5: how to connect the app with my original pictures which are on a external hard disk and, once this resolved, how to create virtual pictures

A friend has installed Lightroom 5 on my MacBook air. he transferred all my picture that were on my IPhone an on Iphoto on Lightroom but without making virtual copies systematically. He put the original (real?) pictures on a external hard disk under Data_photos folder to allow more memory space on my Mac book Air. My problem now that when I connect the external hard disk with my computer the connexion does not happen automatically. it is like if Lightromm does not recognize the path to get connected to the original/real picture and therefore I cannot see pictures with all their potential and I cannot work on these. I am stuck! What should I do to 1) create this link? 2) create then virtual copies in order to be able to work on my computer without been obliged to connect my external hard disk to be able to use the application Lightroom. The friend who helped me disappeared! He is not in Japan and unable to help me.I hope you can help me. I have been looking for support to apple stores, photo shops, computer specialists but I have not found the expert capable to help me. I am leaving in Geneva. And believe that I should have some one with me physically to resolve a problem which I believe is not a serious one if one knows lghtroom an dinformatic basics... thank in advance to come back to me asap !!!!

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.

Not able to delete file from external hard disk

I connected my external hard disk to my macbook pro. But am not able to delete any file since it says the file cannot be deleted when I move it to trash. Could you let me know how to delete a file from the external hard disk?

How is your HDD formatted? NTFS? FAT?
Did you write files with rights? When you strike +I on any file, you can see its rights; if you're read-only, you may change your file's rights.

Want to use a Lacie External Hard Disk with Windows and Mac? Can I?...

Hi, I've just purchased a Lacie Extreme D2 external hard disk, I'm looking to use it to move film clips from my Mac G5 to my Sony Vaio laptop. I'll connect the Mac using Firewire 1 and the PC using USB 1.
I understand there is an issue with setting the compaitibility of the hard disk to either Mac or Windows format but I'm wondering if I can set it to both, so it's possible to transfer these files? The hard disk is Windows and Mac compatible but does it have to be partitioned a certain way?
Any help is much appreciated.
Thanks,
Alex

Format the drive as FAT or use the Mac format (HFS Extended) and install MacDrive on the PC.

HT201269 I am trying to save memory on my iPhone 4S/ ios6. Can I back up all photos to icloud and the external hard disk I normally use for photos? If I then delete photos from the iPhone do the get deleted on iCloud?

I am trying to save memory on my iPhone 4S/ ios6.
1) Can I back up all photos to icloud and the external hard disk I normally use for photos? If I then delete photos from the iPhone do the get deleted on iCloud?
2) Can I back up the newsstand to iCloud and save memory on the iPhone?
3) Can I back up the bookshelf to icloud and save memory on the iPhone?

1. What format is the external drive? It sounds like it's ina format that Macs can't write to. Is it a NAS or NTFS?
2. Easiest thing: just move your iPhoto Library to the external
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.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

Imposible continue the installation of Snow leopard 10.6 on a 1TB external hard disk, what can I do?

Imposible continue with the installation of Snow leopard 10.6 on a 1TB external hard disk. I did the same last year and I continued working but suddenly appeared the simbol with a folder and a question mark and I know this is a problem so I click in the format option to the hard disk and when I tried to install again Snow Leopard, 'cause I want to recover my backups with Time Machine, I couldn't continue because the installation didn't respond to the click in the Utilities option or to next step > continue . Please, What can I do? I'll wait for your answers. Thank you so much in advance.

Hello Melophage,
It is the original hard drive which should have been erased by the previous owner. The problem is, I cannot access it without any OS installed. Or maybe there is a bootable USB or DVD that can do it ?
Just an indication: when I boot without CD inserted in it, it shows a grey folder icon with a questionmark like this one:
Thank you for your help
PS: Yes, I am interested by the replacement pair of grey installation DVDs for my model. Where can I purchase this ?

I currently have a MAC Mini, which has 1 Firewire 800 port. I have a 1TB external hard disk that runs at Firewire 400. Can I insert another external hard drive that runs at Firewire 800?

Here's the deal. Currently running SL 10.6.8 on a MAC Mini. Planning for eventual upgrade to ML. Have a 1TB external hard drive partitioned into two volumes, one volume for Time Machine and one volume for SL which I periodically update using Superduper. Thus I always have a point-in-time bootable backup on the external hard drive.
The MAC Mini supports Firewire 800. However, booting from my current external hard disk is pretty slow, since it only supports Firewire 400. I am considering buying an Iomega MiniMax which supports Firewire 800. Then, I would use the MiniMax as my bootable backup volume, and relegate the older hard drive to Time Machine.
So, question #1 is, can I daisychain the new MiniMax between the MAC Mini and my existing external hard drive? My expectation is that the new Mini Max would run using Firewire 800 and that the existing hard drive would run at Firewire 400 speed as it does today. If it doesn't (e.g., daisychaining in the Firewire 400 external disk with the MiniMax Firewire 800 external disk ends up running the whole leg at 400), my resolution will be to run the existing hard disk off an available USB port and have just the MiniMax running at Firewire 800.
Why am I going to all this trouble? That's question #2. I don't trust upgrades; they always break something. When I upgraded from 10.5.x to 10.6.x, the web directories got renamed, and all of my web apps 403'd until I figured out what happened. Plus, I have accounts for other family members, and in order to ensure their ability to use the computer during my upgrade process, I need to have the ability to fall-back quickly to a known-stable version of OSX. So what I'm trying to do is insulate myself from problems by partitioning the MiniMax into two volumes, taking a Superduper image of my current installation on the Mac Mini to MiniMax external drive volume 1, then upgrading to ML on the MAC Mini, and take a SuperDuper image of that to MiniMax external drive volume 2. Then, if the upgrade results in problems I can't resolve immediately, I can simply reimage the MAC Mini from MiniMax volume 1. BUT ...
... I've read that the ML installation creates a "service and support" partition that is different than the startup disk. I'm concerned that I won't be able to reimage the hard disk in the MAC Mini once I upgrade it to ML because of the partitioning changes it introduces on the startup disk. Theoretically, I +should+ be able to use the disk utility on my SL system to repartition the disk in the MAC Mini prior to reimaging it from my backup, but I'm considering the possibility that the new partition may be of a type that the SL disk utility cannot identify, and might therefore be unable to delete or even detect. So I'm hoping someone else has been down this road and can advise me. Even at Firewire 800 speeds, booting from an external disk is still going to be slow, so I want to be able to restore my SL image to the MAC Mini hard disk.
A little background on me. I work for a major disaster recovery provider. I used to have a Mac PRO G5, which I got used, and the first thing I did with it was install a second hard disk, SuperDupe an image from the first disk to the second, and made sure I could boot from the second. THEN I started using and customizing the MAC. I really feel vulnerable with the MAC Mini, since it only has the single internal hard drive - sort of like going out in public dressed only in a long T-shirt. So my whole thing is, I ABSOLUTELY MUST BE ABLE TO PUT THINGS BACK THE WAY THEY WERE before I do the migration to ML.
Obsessive-cumpulsive? Yep. Anal? You got it. That's why I'm in the DR business.

You may have overloaded the port, following the instructions below it should reset:
+1. Shut down the computer.+
+2. Disconnect all devices and all other cables, except the keyboard and mouse cable(s).+
+3. Disconnect the computer from the power outlet and wait for 3 to 5 minutes.+
+4. Plug the computer back in and turn it on.+
+5. Reconnect the device(s) (one at a time if there is more than one) and test. Test with each port if you have more than one.+

How do i burn idvd projects in a dvd format to an external hard disk

I have an iDVD project but it is too big to burn to a dvd (11GB!) so I was wondering if I can save the proejct like a dvd onto my External Hard Disk. This is really urgent and important for a school project.
Thanks in advance.

iDVD does not care about file size (it compresses a movie file by about 4:1 o the standard mpeg2 format), only about length.
A standard DVD will hold up to 120 minutes of video, but this includes titles, transitions etc.
iDVD encoding settings:
http://docs.info.apple.com/article.html?path=iDVD/7.0/en/11417.html
Short version:
Best Performance is for videos of up to 60 minutes
Best Quality is for videos of up to 120 minutes
Professional Quality is also for up to 120 minutes but even higher quality (and takes much longer)
That was for single-layer DVDs. Double these numbers for dual-layer DVDs.
Professional Quality: The Professional Quality option uses advanced two-pass technology to encode your video (The first pass determines which parts of the movie can be given greater compresson without quality loss and which parts can’t. The second pass then encodes those different parts accordingly) , resulting in the best quality of video possible on your burned DVD. You can select this option regardless of your project’s duration (up to 2 hours of video for a single-layer disc and 4 hours for a double-layer disc). Because Professional Quality encoding is time-consuming (requiring about twice as much time to encode a project as the High Quality option, for example) choose it only if you are not concerned about the time taken.
In both cases the maximum length includes titles, transitions and effects etc. Allow about 15 minutes for these.
You can use the amount of video in your project as a rough determination of which method to choose. If your project has an hour or less of video (for a single-layer disc), choose Best Performance. If it has between 1 and 2 hours of video (for a single-layer disc), choose High Quality. If you want the best possible encoding quality for projects that are up to 2 hours (for a single-layer disc), choose Professional Quality. This option takes about twice as long as the High Quality option, so select it only if time is not an issue for you.
Use the Capacity meter in the Project Info window (choose Project > Project Info) to determine how many minutes of video your project contains.
NOTE: With the Best Performance setting, you can turn background encoding off by choosing Advanced > “Encode in Background.” The checkmark is removed to show it’s no longer selected. Turning off background encoding can help performance if your system seems sluggish.
And whilst checking these settings in iDVD Preferences, make sure that the settings for NTSC/PAL and DV/DV Widescreen are also what you want.

Can I store my Aperture library on an external Hard Disk?

I have a MacBook Pro with very few free space on its internal hard drive. My Aperture library is getting very heavy and i would like to move my Aperture library to an external HD. I know that you can keep files where they are and see them in your aperture library, but the thing i'm trying to do is to STORE AND OPEN MY APERTURE LIBRARY (.APLIBRARY FILE) FROM AN EXTERNAL HARD DISK. Is this possible?

It is possible to put the Aperture library on an external HD as long as the HD is formatted correctly see: Format external drives to Mac OS Extended before using with Aperture
However keep in mind that depending on the HD type and the way it is connected to your Mac performance may be an issue. For the best possible outcome the external drive should have a large cache, high RPM and be connected via firewire.
The other option to explore is to put the masters on an external drive and keep the library on the internal. This will give you relatively good performance using a standard USB drive.

How to format an external hard disk Mac Os Extended (Journaled)?

hello
I connect an external hard disk (2.5' IDE Western Digital Scorpio Blue, WD2500BEVE) via USB or FireWire to my Mac mini. The Disk Utility tool shows an external disk drive of 128 GB - but the disk has 250 GB. How can I format the external USB/Firewire-harddisk 250 GB "Mac OS Extended (Journaled)"?
I tried also to format the disk on a Windows PC (Windows XP). But I could not find a software to format "Mac OS Extended (Journaled)".
Any hints on this? Thanks in advance for any feedback!

As I use theses hard disks in a external hard disk case, I'm asking me whether my hard disk cases do not support more that 128 GB disk capacity. Is that realistic?
It is not only realistic but probably the reason your Mac cannot see more than 128 GB of the capacity of the drives mounted in them. It has nothing to do with the interface between the Mac & case (like Firewire) but instead with the controller in the case that connects the raw ATA drive to that interface. Older ATA standards used a 28 bit LBA (logical block address) scheme to access the disk. For 512 bytes per sector this works out to a maximum of 128 GB of addressable disk capacity. The ATA-6 standard, also called Ultra-ATA/100 or just ATA-100, increased the bits in the address space from 28 to 48, with a disk capacity limit of 2 petabytes.
ATA-6 was introduced in 2001, so any external drive case made before then for ATA drives will be forever limited to 128 G. Even now, some come with a controller that does not support the ATA-6 standard, & essentially none have all the hardware to support its full 48 bits of address capacity. However, since 2 PB (2000 terabyte) drives won't be available anytime soon, all you really need is a case that is ATA-6 or better compliant & supports enough address bits for the largest drive you intend ever to put in it.
Case makers don't usually make this information easily available but many now include a "bullet" spec about the maximum capacity their case supports, typically rounded off to simple numbers like 320 GB, 500 GB, or whatever. If you can't find this info, you can assume that the newer the case the more likely it is to support larger capacity drives, or just buy one with a good return policy & test it yourself with the largest raw drive you own.
