Large dmg onto FAT32-formatted external

I have a 7,7 GB dmg-file which i need to get onto my external drive. I have tons of stuff stored on the drive right now so i cannot reformat it to HFS+.
Is there a way to split the file into two or more pieces so that i can copy onto the drive? I´m looking for a way that´s faster, easier and more convenient that using .rar files which takes forever... Someones said that Disk Utility could make splitted dmg´s that i could copy it to, but i can´t find out how.

I have used the command line hdiutil that comes with the operating system. You can go to the Terminal and enter "man hdiutil" to see how to use it. For a situation such as yours, you would want to create 4 segments to stay under 2GB per segment. The Terminal command would look something like:
<pre style="font-family: 'Monaco', 'Courier New', Courier, monospace; overflow:auto; color: #000; background: #DDD; padding: 0.2em; font-size: 10px; width:400px"> hdiutil segment -o ~/Desktop/outputfilename -segmentCount 4 <path_to existing_image</pre>
You can get the path to the existing image by dragging and dropping the disk image on to the Terminal window. The complete path will automatically appear.

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?

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.

Disappeared: 48GB of files on fat32 formatted external drive

All of a sudden my files from my MB Air (OS X 10.7.2) on a 300 GB Maxtor external drive disappereed. The more info shows 48GB are used on the disc; the format is: MS-DOS (Fat32); and there is another partition for my PC docs, and it's fine. Help!

Ok, confirmed. It is NTFS and according to the permissions I can only read it. The frustrating thing is that it says:
    - Capacity: 74.53 GB
    - Available: 50.35 GB
    - Used: 24.18 GB on disk
and yet at the bottom of the file list it shows "0 items"
Now the dilemma. The harddrive on my Windows laptop is very small (30GB) so I cannot copy all of my pictures to it. I could hook the old harddrive and the new harddrive up to it at the same time and move them from old to new, however...
The new harddrive is supposed to only be for the Mac so my intention was to format it that way. Because I am not sure if/how I am going to need it to resolve this issue, the box hasn't even been opened...so the first question is long term would it be better to have the new harddrive MAC or FAT32 formatted?
I have been assuming that Mac formatting was the preferred route so I am still brainstorming on ways to get the files straight from the old harddrive to the Mac. Could it just be a matter of the files being hidden on the old harddrive? How do I unhide them?

My rMBP with Mountain Lion 10.8 won't recognise my USB3.0 MS-DOS (FAT32) format external HDD

Hi all, first post.
i'm having a big issue with my new rMBP (2.6ghz, 16GB, 512GB SSD) with Mountain Lion OS10.8 . One of the key features of this new laptop is its USB 3.0 'support'. But it doesn't seem to support it
I have a MS-DOS FAT32 formatted 1.5tb Seagate GoFlex HDD USB3.0. This drive is formatted correctly for mac support and has worked very well with my Macbook Pro 13 inch (mid-2009) for a year or more now. This drive has a lot of data on it I need to be able to access regularly. But it won't!
When I plug the drive in to the rMBP the lights on the drive turn on and the disk starts spinning, but OSX Mountain Lion doesn't even recognise it's there. No device appears in the side bar, disk utilities or similar, and no sound is made even when I 'unsafely' unplug itat on
What on earth is going on? USB 3.0 fail
Cheers

I am having a similar issue.
I have an external WD fat32 drive loaded with over a TB of PS3 video data (originally formatted and working well under snow leopard).
I bought a new macbook pro and found the drive inaccessible under Mountain Lion 10.8. (still works fine on my PC and PS3, I no longer have my snow leopard machine).
My research leads me to believe the problem is a bug in the new OS.
The disk utility can see the drive.
The disk utility Validater does report an error and advises I run the Repair tool.
The disk utilty Repair tool reports successful repair but the drive remains inaccessible to ML while still working fine with my PS3 and PC.
I HATE to say this, but I fear my workaround is to go back to using my PC until Apple fixes Mountain Lion.
I suppose I could buy another 2Tb drive, format it with ML and then use my PC to restore the data files. However, that would be an expensive and time consuming experiment with no assurance of success.
Even if it worked, I worry that the next OS update may render the disk unreadable again.
Anyway, best of luck bisherphotos.

File copy inconsistency to FAT32 formatted external USB

Since most recent update rollout I have problems copying files and folders to my external USB drives.
1. While attempting file copy OSX gives error message "File/Folder already present" and fails.
2. Not all the files in the folders are copied prompting further verification of each folder. Occasionally it requires 3-4 additional attempt to further copy all the files.
3. Files copied have their names destroyed and replaced with "~". When trying to rename the file/folder I get error message "Filename already taken", which is absolutely incorrect.
This is extremely worrying, since I have a large amount of photos from various sessions/events I have to retain, not to mention all my personal files.
If anybody experiences the same problem, please add to this thread by all means!
Yours Sincerely

This is not an OS X-specific issue, but rather a FAT32-specific issue.
Namely, this occurs when an error occurs in the FAT32 partition's file allocation table. Remember that FAT32 does not use long filenames for files, but rather uses the old DOS 8.3 (8 characters plus 3 character extension; in FAT32, these start with ~) filenames, and saves the long file names as extended file info in the table.
What you are seeing is a file allocation table where the short filename is already in used but the metadata about the long filename is lost (so the filesystem can't tell whether to replace the file, or create a new 8.3 name and map to it).
Before you use the disk any more, you need to repair the FAT32 filesystem and remove the affected files. I don't know how good Disk Utility is for that, but you can try it. You can also reformat the partition.
This sort of thing can happen if the disk is improperly unmounted (doesn't matter which operating system), or is connected at a time when the system is forced to shutdown without disconnecting the disk (e.g., holding the power button down or power outage). It can rarely happen to a bad sector on the disk.

Using a FAT32-formatted drive as backup disk with Time Machine

For strange and perverse reasons of my own, I'd like to use a FAT32-formatted external hard drive with Time Machine. Is this possible?

No, Time Machine needs a HFS+ formatted drive for its backup folder:
Mac OS Extended or Mac OS Extended Journaled.
_A solution_ if you still want to use the same drive for TM backup and for some Windows files:
Partition the drive before you start using it.
1) Format it (using Disk Utility) as Mac OS Extended
2) Make two partitions.
3) Now you can format Partition2 as FAT32, so you have then two different volumes with each its own format.

How can I put my recently purchased iTunes movies on to my thumb drive and WD My Passport external hard drive. My Mac keeps saying "can't be copy because it is too large for the volumes format

How can I put my recently purchased iTunes movies onto my thumb drive and WD my passport external hard drive.My Mac is saying that can't be copied because it is too large for volumes format

[file] is too large for the volumes format
That is usually an indication that the Volume was never Erased or Partitioned for GUID partition table and Mac OS, and is still in a Windows format.
Mac OS X Extended (journaled) has no such file-size limitations

Disk Utility won't let me format external drive to FAT32

Maybe this cannot be done or the answer is simple and I am missing it. I have a 1.5tb Maxtor drive hooked up via fw800. I want to have 120gb of this as Mac OS extended journaled to back up my internal drive via Time Machine. I want the other 1.38tb to be in FAT32 so I can share files between my windows and mac machines. I keep all of my external storage except for the backup partition in FAT32. I have never had an issue until I upgrades to Leopard and now when I click on the larger partition I only have the option for the 4 mac formats-- FAT32 is not available. I can format the entire 1.5tb to FAT32 but once I try and partition it only mac formats are available. I forgot to mention I just did the upgrade to 10.5.1 and the issue is still present.
How do I format the smaller partition as mac os extended journaled and the larger as FAT32? Any help is appreciated.
Thanks so much,
Patrick
PS. I did a search but did not find anything.

It may depend on the type of partition table scheme you are using (see bottom of page in disk utility for that says Apple Partition Map/APM, GUID Partition table/GPT or Master Boot Record/MBR partition map).
MS-Windows can read MBR scheme only (64 bit MS-Windows supports GPT, according to MS). If you have Apple Partition Map, your disk won't be usable on Windows. I suspect you have APM partition table and hence the disk utility is not giving the option for FAT32 format, since you can't use it under MS-Windows.
On the Mac side, all 3 schemes are readable (for bootability, you'll need APM on PPC Macs, GPT for Intel Macs). Time Machine doesn't need a bootable disk, but I'd suggest APM/GPT if you are using PPC/Intel macs respectively (but I'd think either will work for Time Machine, if you have a mix of Macs).
But here's the catch - Apple says Time Machine won't work with drives with MBR partition map (even though Macs are MBR-aware), so the issue for you is Time Machine's ability to use MBR drives. http://docs.info.apple.com/article.html?artnum=306932
I suspect unless you are on an Intel Macs (OS X) and use only 64 bit MS-Windows (using GPT)/Itanium, using the same disk for TM and FAT32 sharing between Mac and Win worlds is not possible. Not the desirable answer.
If you do want to experiment, make a temporary setup and try it out on both Mac side and Windows side first (on all your machines), before making a "production" system. You can select the DISK (first line on Disk Utility for that disk, not second line) and click on Options at the left bottom (it might have to be erased first) and then select the type of partition scheme. Note formats like HFS+/FAT32 are a level lower in the hierarchy than partition map/table.
Let us know what you find out/decide?

Can't format external drive as FAT32

I just bought a brand new 4TB Seagate external HDD with the notion that I would hook it up to the back of my Time Capsule. I will want this drive accessible for both Mac and PC. According to this page my only real option then is FAT32. Here's my problem. When I open Disk Utility and select my drive, and then the Erase tab, no option will work for erasing the disk. I get an error. If I select the volume (indented under the drive) and the Erase tab, I don't get FAT32 as an option. I have the "Mac OS Extended" and "exFAT" as my only options. I can format the drive successfully using either of these two. However, the Time Capsule only recognises it has been formatted as "Mac OS Extended" as expected. Can anyone tell me how I can use Disk Utility to format the drive as FAT32 format?

Ok, that worked.... kind of. When I selected the Partition tab and '1 Partition' it allowed me to format it as FAT32. I went and plugged it into the Time Capsule, and the drive shows up in the Airport Utility under the "Disks" tab. However, something still isn't kosher here. When I open a Finder window and click on my Time Capsule, I see the external drive. But the file I copied onto to it immediately after doing the format doesn't show up. It appears as though the drive is empty. Then after about 30 seconds I get an error message that my drive can't be found.
On a side note, I have formatted the drive as exFAT, but when I plug it into the Time Capsule, it does not recognize it all. Because the page I linked to in my original post did not specify exFAT that's why I wanted to try FAT32.

Can I get files from a Mac formatted External Hard Drive onto a PC

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

Unable to transfer large files from MB to External HDs

Hi,
This may be an unusual one. My 1st edition Macbook won't let me transfer large files to my external hard-drives, either by USB, Ethernet or wirelessly through my home wi-fi network.
I've started video editing so I'm importing DVcam tapes through firewire from the camera. A full DV tape translates to about 8-12gb I think.
Using iMovie and saving the import to my Freecom 3.5inch network harddrive vis USB or ethernet, it fails saying 'Unexpected error, error code 1309'.
When I try quicktime pro instead to import the tape to the external HD, I get 'Operation could not be completed, An attempt to add a resource to the file failed'. This happens too with my WD 2.5inch external drive.
However, there is no such problem when I import to the MB's internal harddrive. When I then try and shift the large file off the laptop to an external drive, via USB, ethernet of wirelessly, for editing and save keeping, it fails half way through.
I have the same problem when I try back-up my 17gb virtual windows machine I use with VMware fusion off the laptop to an external drive.
I am currently burning an 18gb iMovie project from the MB's internal HD, over 5 DVDs using Toast's disc-spanning and will reimport them to the external, which is really time consuming.
Also to note, Final Cut Express doesn't have these problems as it seems to break up what would be an 18gb movie file into several smaller files, which my MB is quiet happy to let go onto an external drive. However, the problem re-emerges on Final Cut Ex when I try and import a HDV tape. Possibly FCE isn't breaking them up into small enough pieces for my MB to handle?
Any ideas why this is happening and what I can do to fix it? Or does this mean a new laptop?

I'm a bit late to the party, but specifically there's a 4GB file size limit in the FAT32 format that is standard on many external hard drives. I've run across this problem before, and usually it copies over most of the file and then quits when it reaches the limit.

How do I copy an iPhoto library, which is on an external hard drive, onto a new external hard drive?

I'm running out of space on my external hard drive, so I was advised to buy one with triple the amount of space. So, I need to copy my current iphoto library, which is on an external hard drive, onto a new external hard drive. I thought I could just drag and drop it in, but that doesn't seem to be working.

Make sure the external drive is formatted MacOS Extended (Journaled) and then drag the iPhoto Library to that drive using the Finder.
Then double click the library in its new location to open it in iPhoto. Test it thoroughly, if it is working, before deleting the original library on the internal drive.
To check the format of the drive, see (it says Aperture, but the same applies to iPhoto): Format external drives to Mac OS Extended before using with Aperture

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.

Copying large video files to PC-external HD

I need to deliver a large Quicktime-file (5,87 Gb) edited in FCE to someone who will open it on his PC in Avid.
It seems to be complicated:
First problem is conversion - I need to convert my QT-file to a Windows Media file, right?
This can be done with a conversion programme, i.e. Microsoft Expression Encoder that I have installed on a PC laptop.
But how to move the 5,87 Gb file to the PC?
I have an external HD formatted FAT32, but that only takes files up to 4Gb max.
Is there really no way to copy a large mov.file on to an external hard drive that can be read by a PC?
Tog o around the problem, I have tried to make an avi.file by exporting from FCE with Quicktime conversion - but the quality is really bad.
Also making a smaller QT-file (that does not exceed 4 Gb limit on the HD) does not look good when compressed a second time in Expression to a Windows Media file.
So, what to do?
Can PC's read NFTS-formatted HD?? I guess not, I tried onc,e but maybe I didn't format it right.
Sorry for all these questions in one go - hopefully there's a way to work around this annoying problem...

For file transfer, here's what I suggest (sort of in order of recommendation):
Use a network connection. Both computers (your Mac & your friend's pc) on the same network; turn on file sharing on your Mac, log the pc on to your Mac and copy the file(s).
Use an FTP connection via the internet. You and your friend will both need an FTP client.
Use an NTFS formatted external hard drive. All modern pcs use NTFS (Windows 2000/XP/Vista/7). You will need a copy of NTFS for Mac (or similar utility) on your Mac to write to an NTFS formatted disk.
Use a Mac OS Extended formatted external hard drive. Your friend will need a copy of MacDrive (or similar utility) on his pc to read files from a Mac OS Extended formatted disk.
Burn your 5.87GB file to a dual-layer DVD disk. Use the Finder to copy the file to DVD media & burn the disk. Your Mac will need to be able to burn to dual-layer DVD media; and your friend's pc will need to have a DVD drive to read the disk.
