Want to partition a new External Hard drive for both pc and mac

Hello!
I am going to partition a new Seagate external hard drive for both my pc and mac. What format do I choose for the PC partition? MS-DOS (FAT), ExFAT, or Free Space.
Thank you!
Nikki

If I may suggest:
Drive Preparation
1. Open Disk Utility in your 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. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
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.) 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 can take up to several hours depending upon the drive size.
7. After formatting has completed select the main entry for the new drive (mfgr.'s ID) then click on the Partition tab in the DU main window. Click on the large partition rectangle then click on the Add [+] button. The partition should divide into two equal volumes. Resize as you prefer. Select the second or bottom volume to use on the PC. Set the format type to ExFat, then click on the Apply button. Wait for the two volumes to finish mounting on the Desktop.

External hard drive for both windows and mac

hello, all - just bought a western digital 500gb my book premium edition external hard drive. will be using for both pc and macbook, not necessarily to share files (though i may on occasion), but rather as a backup. been researching the discussion boards and concluded that i should use it as pre-formatted fat32. few questions...
1) if i do use to share files, from what i understand i will be able to read windows files with my mac but i can't read mac files with windows (unless i have macdrive installed). is this correct?
2) since mac can read/write to fat 32, is it necessary to partition the drives and keep the files separated? i talked to a "computer guy" earlier today and he said i should consider having two completely separate external hard drives as having files from two different operating systems on the same drive could cause major problems for both... i didn't really believe him.
3) i have seen different posts stating using fat32 format for mac limits file size to 4gb. another post said 32gb. which is right? i have os is 10.4.7 if that makes a difference.
thanks in advance for any insight.

2 - i don't mind partitioning at all. but he strongly suggested not even partitioning but using two completely separate hard drives. yeah, the 500gb was a bit overkill, so if i can use it for both as opposed to one and buying an additional, i'd rather.
2/3 - if i partition, is it best to divide it into ntfs and hfs+? or should i keep the pc portion fat32? if the mac portion is hfs+, can i store any size file? i have videos that are anywhere from 10-20gb, and i'd like to get them off my computer and into the external drive.
thanks.

Partitioning 1.2T External Hard Drive for Time Machine and PC backup?

We have a 1.2T Seagate external hard drive. I partitioned it so that I could use part of it for my Time Machine backups and want to be able to use the rest of it for the PCs in the house. I formatted the rest of the space using the Disc Utility and the MS-DOS option. Was this the wrong choice? I can't use the PC space on the hard drive on my PC. It says there are 0 bytes available.
Help?

no, that was the right choice. I don't know what's going on there. you just might need to reformat the whole drive. also check the partition scheme for the drive. it should be GUID. if it's not GUID repartition the drive with GUID partition scheme.

How can I use my external hard drive on both pc and mac, but also being able to use it to back up my mac data?

I want to be able to transfer some of my files from my laptop to my macbook, but not all of them. I have a NTFS external hard drive and I have heard about reformatting it so that it can read/write across both systems, but can I still use this hard drive to back up the data on my macbook? If I can, how should I go about reformatting the hard drive?

FORMAT TYPES
FAT32 (File Allocation Table)
Read/Write FAT32 from both native Windows and native Mac OS X.
Maximum file size: 4GB.
Maximum volume size: 2TB
You can use this format if you share the drive between Mac OS X and Windows computers and have no files larger than 4GB.
NTFS (Windows NT File System)
Read/Write NTFS from native Windows.
Read only NTFS from native Mac OS X
To Read/Write/Format NTFS from Mac OS X, here are some alternatives:
For Mac OS X 10.4 or later (32 or 64-bit), install Paragon (approx $20) (Best Choice for Lion)
Native NTFS support can be enabled in Snow Leopard and Lion, but is not advisable, due to instability.
AirPort Extreme (802.11n) and Time Capsule do not support NTFS
Maximum file size: 16 TB
Maximum volume size: 256TB
You can use this format if you routinely share a drive with multiple Windows systems.
HFS+ ((((MAC FORMAT)))) (Hierarchical File System, a.k.a. Mac OS Extended (Journaled) Don't use case-sensitive)
Read/Write HFS+ from native Mac OS X
Required for Time Machine or Carbon Copy Cloner or SuperDuper! backups of Mac internal hard drive.
To Read HFS+ (but not Write) from Windows, Install HFSExplorer
Maximum file size: 8EiB
Maximum volume size: 8EiB
You can use this format if you only use the drive with Mac OS X, or use it for backups of your Mac OS X internal drive, or if you only share it with one Windows PC (with MacDrive installed on the PC)
EXFAT (FAT64)
Supported in Mac OS X only in 10.6.5 or later.
Not all Windows versions support exFAT.
exFAT (Extended File Allocation Table)
AirPort Extreme (802.11n) and Time Capsule do not support exFAT
Maximum file size: 16 EiB
Maximum volume size: 64 ZiB
You can use this format if it is supported by all computers with which you intend to share the drive. See "disadvantages" for details.

Using Seagate External Hard Drive with both PC and Mac

So I bought this hard drive knowing that it can be used back and forth between Macs and PCs. I currently have a PC, but it's pretty old and I figure I will be getting a Mac after it dies. But currently I want to use it to get files from a Mac computer and when I connect it, it says "read only". How do I configure it to be able to transfer files with a Mac?

I want to buy a new external hard drive.

I want to buy a new external hard drive, I have an iMac now, I most likely will buy a mac pro this winter. I want to buy a hard drive that will be able to handle the highest quality video, AND work with my iMac now. Thanks

And finally:
Make SURE you format the drive as Mac OS Extended, journalling optional but recommended.

I bought a new external hard drive for backups, but time machine won't do a full back up. I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?

I think it is remembering backing up onto previous external hard drives, which I don't own anymore. How do I do a new full backup?
When I bought the new (used) iMac, I also bought an external hard drive for backups. It worked fine, but my husband stole it.
Then I bought a new external hard drive (Seagate) and it worked fine for three weeks, then died.
So I just got a new external hard drive, which was put together from an internal hard drive and a hard drive enclosure.
Time machine did the first backup today, and it should have taken 9 hours like it did on the previous first time full back up. Instead, it took 30 minutes. That can't be right. I want to start over and do a full backup to make sure everything gets onto my new external hard drive, but I can't figure out how to do that. Please help.

Triple-click anywhere in the line below to select it:
tmutil compare -E
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command will take at least a few minutes to run. Eventually some lines of output will appear below what you entered.
Each line that begins with a plus sign (“+”) represents a file that has been added to the source volume since the last snapshot was taken. These files have not been backed up yet.
Each line that begins with an exclamation point (“!”) represents a file that has changed on the source volume. These files have been backed up, but not in their present state.
Each line that begins with a minus sign (“-“) represents a file that has been removed from the source volume.
At the end of the output, you’ll get some lines like the following:
Added:
Removed:
Changed:
These lines show the total amount of data added, removed, or changed on the source(s) since the last snapshot.

HT4718 I want to install a new internal hard drive for my Macbook (13in, Late 2009) and restore to factory settings. However, I want to keep my Mac OS X Snow Leopard.

I want to install a new internal hard drive for my Macbook (13in, Late 2009) and restore to factory settings. However, I want to keep my Mac OS X Snow Leopard., which I downloaded from the app store. How can I restore computer with the updated OS?

What I did on our two computers was partition the hard drive so that both Snow Leopard and Mountain Lion can be used on the computers. This allowed me to be able to retain/use older applications and games on the Snow Leopard partition. This will allow you to do a clean install of Mountain Lion on the newly created partition. The Mountain Lion installer has a button that allows you to select another drive so you don't install it over Snow Leopard. I cleverly name one partition Snow Leopard and the other one Mountain Lion so I wouldn't confuse the two (I never claimed to be smart).
To partition, you need to have sufficient free hard drive space (I suggest 50 GB minimum). Boot off the Snow Leopard DVD or the disks that came with the computer and use Disk Utility to partition your hard drive into two partitions. If you plan to make Mountain Lion your primary OS, then you can reduce the size of the Snow Leopard partition so most of the free hard drive space is available for Mountain Lion. While booted off the disk, you can install Snow Leopard on the partition you want it on.
Restart and download Mountain Lion, remembering to select the correct partition before installing. I would make a copy of the installer and move it out of the Applications folder because the installer self destructs.
After getting all that sorted out, I found that while booted in Mountain Lion I could access the Snow Leopard partition. That allowed me to drag files and applications from Snow Leopard to Mountain Lion. Applications that won't work with Mountain Lion will be grayed out with a slash through them.

HT201250 new external hard drive for Time Machine backup suggestions?

Ok, I have 3 external hard drives; unfortunately I've used them on my PC and they are read only on my iMac. So, I need to buy a new external hard drive for Time Machine backup. I'm a little confused; can I buy any EHD and them format it so Mac can use it or are there special EHD's I need to purchase?
Anyone have a particular EHD that is working well for you? Thanks, Blue

Unless you need all three external drives for your PC, you can reformat in one of them in Mac OS Extended (Journaled) for use with Time Machine. However, since Time Machine backs up hourly, you'd need the external drive to be running constantly. That means ventilation of the drive becomes an issue since some, such as Seagate, can get very hot in their sealed enclosures. Some drive manufacturers try to get around this by spinning down the drive when not in use, but I've read complaints that that doesn't play well with a Mac. So whether you reuse one of your current externals or get a new one, it's a good idea to keep the drive's ventilation in mind.

New Computer and New External Hard Drive - why do folders and photos not show up?

I replaced my desktop with a new laptop and external hard drive. I transferred photos from the desktop to the external hard drive. Lightroom 2 only shows the mapped hard drive, but does not show any folders or photos. Can Lightroom be set up to house all the photos on an external hard drive rather than using space on the internal laptop hard drive? Do the photos and folders need to be imported again into LR2? The photos are available for viewing when you search folders, but they open up in Photoshop not LR2.
What should I do to configure imports to be housed on the external hard drive? Is this wise? I will not be able to hold all the photos on the laptop internal hard drive. Photos used to be JPEG and DNG from D700. I am starting to see NEF. Does this replace DNG? Besides RAW I also need to have JPEG for other family members to access photos on other computers connected to the network. I am watching a tutorial DVD and slowly picking up how this all works. Let me know if I am not using the correct terms.
Hardware: HP laptop w/64bit, Buffalo 1TB RAID hard drive.

Lot's of questions here. I'll do a few.
Yes Lightroom can work with images on external drives. As many drives as you want.
I assume from what you said in your original post that you have had lightroom installed on the old desktop and now wish to transfer your catalogue and all files to the external drive and work from that.
So what you would do would be to transfer the entire contents of the lightroom folder on your old computer, except for any images, to the same location on your new laptop. This would include the catalogue files and any folders containing previews. Then you would copy all your image files to the new external hard drive. When you open lightroom you can then select the catalogue you copied from the old computer and open it. In the the folder pane in the library module you can then right click on one of the folders and select "locate missing files". Then you just need to point light room to the new location of your images. You may or may not need to regenerate all your previews.
I store all my images on external hard drives and I even run the catalogue and previews from the same external drives. I have backups of all my images of course. I have light room make backups of the catalogue to the C drive on my laptop so that the original and the backup are stored in different locations.
NEF is the proprietary file system for raw images used on Nikon cameras. DNG is a universal raw file format developed by Adobe. You can convert your files from NEF to DNG on import, but as Lightroom can read both types of files it is not necessary. At this point in time if you are using lightroom you should get similar results from either type of file.
To store imports on the new external drive you can you tell light room to copy the files to the new drive or you can manually copy the files to the new location and have light room import From the current location.
Hope this helps

How do I format a new external Hard drive for Mac?

Simple question I know for many of you out there but I could do with some advice as I have never done this before. I would like to buy a new external hard drive to store my music and photos on. I will get one with firewire and usb2 connectivity.Could someone walk me through the steps needed to format and prepare a hard drive for use with my Macbook (if it is not already Mac formatted). Will any brand of hard drive work with Mac or are some better than others?

In addition to what Templeto Peck said, make sure that you select the formating to be OSX Extended.
As far as the best esternal drive, type into the "Search Discussion" box: Best external hard drive. This will bring you to several previouslly posted threads that discuss quite thoroughly your question. The following is extracted from one thread:
The best drives are those that use the Oxford 911 chipset. I like the Mercury Elite Pro drives from OWC, but there are plenty of others that use the same chipset.

I want to use my 1TB Seagate Hard drive for time machine and transferring files from Mac to PC.

For about a year I've been using my 1TB external hard drive for only time machine. To be honest, it wasn't until today that I tried to connect my hard drive to a PC and realize it isn't compatible. I read about partitioning the hard drive so that it can work both for time machine and transferring files between pc and mac. I'm not what you would call tech savvy, so I was wondering if I can get some advice on how to do this.
Thanks in advance.

To do it, you have to partition the hard disk, so you will have one partition for Time Machine and another one to store files and use them in a PC and Mac. To create the partition, follow these steps > http://pondini.org/OSX/DU3.html
In order to read and write in the external disk on the PC, you have to select "MS-DOS (FAT)" as "Format". If you choose any other option, the PC won't be able to read your external disk. Apart from that, note that you can't use files bigger than 4 GB with FAT. If you want to use the external disk with files bigger than 4 GB, you have to format your new partition in exFAT, and you have to do it on a PC

Any EASY, simple to use external hard drives that are PC and Mac interchangeable?

I have a new Mac Book Pro, running Mountain Lion. I am new to Mac; my old laptop is a Dell running Windows 7.
I would like to move over ALL my pictures and files from the Dell to an external hard drive (EHD) that is also Mac-compatible. I want all the pictures and documents SAVED and easily retrievable on the EHD, but probably don't really need *ALL* of them on the Mac.
Does anyone know of an EHD that will do this? One that is really super easy to use and won't need "reformatted". (I don't want to have to try to deal with that!)
I just want to put ALL my stuff from my Dell on an EHD, then move over SPECIFIC items from that EHD to my Mac.
Any advice? Recommendations? THANK YOU!

Bob,
I'm sorry, my message was unclear! No, I'm not looking to hook up two computers at one time to one EHD.
I'm just looking to be able to use one EHD, and go back and forth between it and the Mac or Dell, getting stuff off one, and putting stuff onto the other.
I have all my old Dell files and photos already on the EHD. I was afraid that once I formatted the EHD that those files from my Dell that were already there would somehow no longer be accessible to transfer to the Mac? But it sounds like this isn't so?
So, to clarify: I would like to continue to have access to the files on the EHD (from the Dell). Once I format the EHD, will those files still be accessible to me, to either leave "as is", or transfer to the Mac, now or later?
THANK YOU!
