Help formatting external HD

Hiyall - Following problems with a previous HD, I realize belatedly I'm supposed to format these things optimally when they come out of the box.
When I go to Disk Utility I get cold feet!
I am running 10.5.7 with a 2.2G intel on a MacBook
I have a WD My Book Studio edition (yes I know, there have been problems...)
I gather from another that I want it GUID partitioned and in Mac OS Extended (Journaled) format.
Q: Is this correct?
Q: If I uncheck the install OS9 drivers, is that permanent? Do I care? Perhaps, right ... that is, if I have files that run on a program that only runs on OS 9, then I need to keep this checked, right?
Q: The partitioning is what comes later, right, with the indented volumes that appear ... so I don't worry about that when erasing at the top level?
Q: What does partitioning get me? Is it like a firewall for failure within the HD? So, say, would I make a few partitions and keep photos in one partition and work files in another??
TIA!

Is this correct?
Yes.
If I uncheck the install OS9 drivers, is that permanent?
Until the drive is erased again.
Do I care?
Since you'll be partitioning it as GUID which Mac OS 9 can't use anyway, no. Neither setting will affect Classic's ability to use the drive.
The partitioning is what comes later, right, with the indented volumes that appear ... so I don't worry about that when erasing at the top level?
No, you don't.
What does partitioning get me?
It reduces the chance that the whole drive will become unreadable due to a software issue, but doesn't protect against hardware failures. It also makes it possible for multiple Mac OS X versions and other OSes to be installed on the drive.

How is the current EHD formatted?

HT1338 I was backing up my MacBook with Time Machine on my new (correctly formatted) external hard drive. It was going fine when my 2 yo knocked the hard drive. Now TM said "failed" and the Mac refuses to recognize the external hard drive. Help please?

I was backing up my MacBook with Time Machine and using my new (correctly formatted) external hard drive. All was going well when my 2 yo knocked the disk leading to a "failure" by time machine (Latest Backup: Failed). Now the MacBook will not even recognize the hard drive. I have rebooted, tried all I can think of, but no acknowledgement of the drive. The drive itself makes noise and vibrates as if working, but nothing from the Mac. Please help or $100 down the drain... Thank you.

You may have already done these resets in the "tried all I can think of " portion of your post.....if not then here they are.....

Can I install my time machine back up onto a properly formatted external hard drive?

I have a MacBook Pro with a 750GB harddrive, with 500+ Gb of data on it. Just before I traverse to Europe, I did a TimeMachine back up.
I now want to give my Mac to a friend, and buy a AirMac when I get home. Even if I get the one with the largest drive it will not hold the full 500+'back up.
I have an 8 year old Mac Book pro at home as well. It will be a few months before I can buy the new AirMac. So my question is ....
Can I install my current backup on a properly formatted external hard drive, and will it then run like a computer --until I get my new AirMac?
Thanks for your help (and please don't be too tough on me for what may see to de a dumb question)

The Time Machine backup is not bootable
You will have to install Leopard first

FAT formatted external hard drive is not 'readable by this computer'

Hello support community
The problem: when I insert my 'FAT' formatted external hard drive (Samsung M3) into my mac book pro it comes up with the error message that says "the inserted disk is not readable by this computer" and I therefore cannot access the files.
The story (potential further details):
1. I had a problem with my mac where it took hours to load each time I turned it on, would only work when power was plugged in etc. so I had to reformat my mac hard drive (when I tried to veriify it said repair, that wouldn't work). So i'm starting with a recently reformatted, clean mac.
2. Before doing this I reformatted my external hard drive (whilst on windows machine) to FAT32 (so I can use on both windows and mac) so that I could back up my files.
3. I then transferred files from mac onto external hard drive and then also put them on a windows machine.
4. After reformatting mac hard drive when I then tried to transfer files back onto the mac I get the 'not readable' error.
The technical details:
Thank you very much indeed anyone who can help or can try and help
Cheers
Andy

Erase the drive and reformat using your Mac (Disk Utility)

Hey, can i clone my Macbook Pro internal hard drive and then paste it all onto a formated external hard drive, then make the Mac use the external as the primary hard drive?

hey, can i clone my Macbook Pro internal hard drive and then paste it all onto a formated external hard drive, then make the Mac use the external as the primary hard drive? please help for i only have around 618mb left out of 189GB!!!!!!!!!!!!!!!!

If what doesn't work?
If cloning your internal drive to the external drive is not successful, I expect CCC will tell you so. Assuming that doesn't happen, you will have a bootable replica of the internal drive on the external drive once CCC has finished.
You can then do any of several things:
1. Replace your internal drive with a much larger one (320GB or 500GB, or even larger), and clone the external drive's contents onto the new drive so you'll have all your data in one place. Note that if you do this, you'll also need to buy an external drive that's large enough to back the new internal drive up on.
2. Boot from the external drive as a temporary measure while you clear at least 30-40GB of data off the internal drive, allowing you to keep using it and saving small amounts of data to it. The external drive will then contain the only copies of the files you've deleted from the internal drive, so you'll need a seond external drive large enough to back both the other drives up on.
If you can't comfortably clear a minimum of 30GB off the internal drive, you really need a larger internal drive right now, and you shouldn't bother fooling around with the inadequate one you have — you'll just quickly overfill it again.
3. Replace the optical drive in your MBP with a large conventional hard drive, giving you two hard drives inside the machine. You will then need one or more external drives large enough to back up both of the internal drives.
If you sense a theme here — back up, back up, back up — you are correct. It's flat-out foolhardy to own or use a computer without maintaining complete, up-to-date backups of everything at all times.

NTFS formatted external hard disks?

does mountain lion supports writing on NTFS formatted external hard disks?

I'm getting immense slow-downs using Tuxera NTFS (latest release as of August 2012). I moved my home folder to an NTFS shared drive. Reading/writing to the cache while browsing in Safari is slow. Takes about 30 seconds for Finder to open my NTFS drive, takes about 1 minute to open an app and close the app. If I disable Tuxera NTFS and make my drive read-only, everything goes back to snappy performance (except for write-errors, since disabling Tuxera means I can't write to my home folder).
What shocks me the most is that if you visit the Tuxera community forum on their corporate website, none of their support representatives have helped their customers since the release of Tuxera NTFS for OS X Mountain Lion. It's as if the company realized they messed up, so they went silent.
I'm about to try the latest version of Paragon. I had it for OS X Lion, but it corrupted my entire drive after 2 months of use, which is why I tried to give Tuxera a shot. Here's to hoping Paragon has fixed their issues.

Can i use windows migration assistant to transfer files from my windows formatted external hard drive to my mac?

I have a windows formatted external hard drive and a macbook pro. I was wondering if i could use the windows migration assistant to transfer files from my external hard drive to the mac

No.
Just connect the drive to your Mac. The Mac can read most Windows formats (it cannot WRITE Windows New Technology File System (NTFS) formatted drives.

Transfer files from Mac formatted external drive to PC formatted drive

i need to transfer quicktime files (that were captured from video with FCP) to a PC formatted external drive (for editing them in after effects on a PC). the files can be transfered by burning them on a DVD, but that will take a very long time and waste many DVDs because i have 60 GB of material... can this be done (without having to purchase expensive software)?

thanx tom,
first of, i like that you made the link appear as one word. how did you do that? it's really cool!
i downloaded the program, but i'm not sure how to use it... reading the guide just made me more confused... if i understand correctly, it will automatically reformat ALL my files to NTFS-3G ones, which are not as stable... i'm a little scared to install it... though i may have totally misunderstood what it says. i see mostly black when i try to read these kind of things...
anyone out there have experience with this program?

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.

Paragon also has a program (suite) that will convert NTFS <=> HFS+ without data loss (but have backup never use something wo one!)
And Pargon has kept up with Lion while others have not or have stopped development and works best with PC drive cases with low overhead and fast reliable copy operation.
The demo is also fully functional for 30 days.

Itunes library is on a mac formatted external hdd: can windows recognize it

subject pretty much says it all. can windows recognize my mac formatted external hdd? i know when i had my ipod formatted to windows, the mac recognized it, but will the mac formatted drive allow windows to see it, play the music, and possibly move it to my ipod?
thanks!!!

Default, Windows will not recognize Mac formatted disks.
A number of applications can enable Windows to read them.
Take a look at this page: http://www.macwindows.com/disks2.html
I don't have experience with any of the apps. mentioned on that page, so I can't tell you how they perform.
Maybe posting in the iTunes for Windows forum will result in specific information.

Freely programmed search help with external mapping

Hi all.
I have a freely programmed search help to search for physical inventory items.
I map some data from the component where i use this search help to this search help via external mapping. This works fine.
But in the search help I want to be able to change the mapped data to perform a new serach. When I change the data and start the action to search again (in the serach help component) I still get the old field value from context so that the search returns the same result. When I close the search help afterwards the changes are suddenly visible in the using component. So my entered data are somehow transfered to the original context but not to the context of the used component.
Any ideas?
Thanks
Sascha

Hi Sascha,
I would suggest, that you do not work with the externally mapped attribute.
Try to copy the value to a "local" attribute in the searchhelp context while WDDOINIT of the component.
This is the attribute you should use for the search.
When you change the searchvalue, it is only changed in the comnponent.
To get the values back to the calling component you need to copy it back while you call the action submit or exit.
Hope this helps
Best regards, Matthias

Can't write to a Windows formatted external hard disk

I moved the Windows XP formatted external hard disc from the Windows machine to the Imac. I can read files on the hard disc, can write from the external to the Mac, and can work with the files once they are on the Mac. But I cannot write to the external. I lack permission, the error message says.
I talked with Apple via my AppleCare arrangement. They tell me I will have to reformat the disc for the Mac before I can write to it.
The problem with the recommendation is that that disc, 160 gb, is over three-quarters filled with backup files for the home network. I can't afford to lose them.
The puzzle is that the network sharing is uneven. So I'm led to think there is some problem with my setup. From the Mac, I can read and write to two Windows computers and the internal hard disc, the C drive, of the third. When the external hard disc was attached to that third computer, I was never able to see it from the Mac.
None of the Windows machines can see the Mac.
Any suggestions?

When you go over a network, the Mac doesn't have to worry about writing to the destination disk, it just sends the appropriate TCP/IP packets and lets the PC that is serving the disk worry about writing to the disk. When the disk is connected directly, then the Mac has to know all about writing to that file system.
It does seem to me that if Apple could read from the drive, they should be able to write to it, but apparently that was more complicated and they didn't implement it.
As for the windows boxen not being able to see the Mac... have you considered installing Bonjour for Windows onto the PCs? My wife has PCs and I have Macs, but we're all networked together. We were having some networking issues, trying to share printers. So I had her install Bonjour on one of her boxes. Suddenly, all our networking problems went away. She could see my printers, and all my drive shares.
So you might want to think about turning thinga around and serving off of the Mac.
