Partitioning My External Hard Drive - need some help

Greetings,
Recently, i have bought an external hard drive, then enclosed it with a casing and connected it through firewire 800 on my iMac 20" 2.0Ghz late 2007 model. what i want is , on my external hard drive, i partitioned it into two, then one partition for my mac, and the other is for windows. wherein windows partition can also be read/write from my mac, and vice versa on my windows;
am looking for a suggestion on how to make the other partition, the windows partition to be read/write from my mac, and can also be read/write on my windows;
Really appreciate any help; thank you in advance.

New to daisy chaining my external hard drives need some guidence on this

I have 2; 3.5 inch 7200rpm 1TB hard drives, & bought some external enclosures with firewire ports for them.
what would the steps be to set them up?
some things I cannot seem to get a clear answer for even after Google searches is;
say I have drive A & drive B together, with drive A plugged into the firewire port on my mac & drive B plugged into drive A. If I only need to work with content on drive B, do I have to have drive A running as well? even if I do not need to work with it?
I notice in mac os that devices show up as no names, well if I need to eject my drives how can I tell which is which when they both show up with the same no name? I dont want to accidentally eject the wrong drives in the wrong order.
So to prevent something like this I would like to know if there is a way to get mac os to name each hard drive? say drive A would be called photos & drive B music. Is there a way to get windows to see them with these same names as well as in mac os?
another thing is I have windows xp pro installed through parallels on my mac & would like to work with my daisy chained drives in this as well.
what ever I do I dont want to screw up my drives, I have important data on them.

You can rename the drives to be just about anything you choose. That will help you to make sure that you are disconnecting the correct drive. As for the daisy chaining issue, I have found that even though the enclosures have the ports for this, I tend to see more issues with random disconnects. As near as I can tell, the Firewire port may not be providing sufficient power to drive two 7200 RPM drives at the same time. I personally prefer to use one drive on my FW800 port and a second on my FW400 port. Yes, one of the dries gets a lower bus speed, but for the increase in drive stability, it actually tends to perform slightly better overall since there are fewer drive disconnects under heavy load.
You reference Windows XP and Parallels. Parallels allow you to specify to connect a drive to the Mac OS side, or to the virtual environment running Windows. This is easily managed. If you are referring to Boot Camp, then yes, they will still work, as the Boot Camp drivers you should have installed would have installed drivers for the Firewire port. One other thing to keep in mind is that depending upon how the drives are formatted, you might have read-only access to the drives under one of the two OSes. You can buy/download drivers to give you full read/write access to HFS+ drives under Windows, and similarly for NTFS drives under Mac OS. Also, if you choose to connect the drives to a virtual Windows environment, then they will not be available to your Mac OS unless they are shared from the Windows side.

Hello, I need help to retrieve deleted information to partition an external hard drive. What should I do?

Hello, I need help to retrieve deleted information to partition an external hard drive. What should I do?

I'm not about the question, and giving you the right answer requires me to ask a few more questions.
Do you want to retrieve deleted information for future usage, or to completely delete a partition? The latter is straightforward: simply erase the partition. The former is more complicated: it's very difficult, even using available commercial software, to recover deleted information. If the data is important, you may want to contact a professional like DriveSavers. It won't be cheap.

HT201250 Do I need to partition my external hard drive if I'm using Time Machine and other storage?

I never used Time Machine before. I was storing select files on my external hard drive as well as using my libraries (IPhoto, ITune, IMovies) directly off of the external hard drive. That hard drive is giving me problems, so I bought a new one. I want to set up Time Machine on this one, but I also want to keep my active libraries on it. Do I need to partition the external hard drive?

You can partition the new drive, just don't make one of the partitons a TimeMachine drive, save a TM for a entire drive with more space than the boot drive as it saves "states" thus requires more room than most people expect.
I highly advise one drive to one drive for backups, and not placing too many backup eggs in one vulnerable hardware basket basically.
Drives are cheap, data is not. Hardware can fail just as often as software, so you need a multiple backup and storage stragedy to protect even against theft and fire.

What does it mean to "partition" the external hard drive? Is it something I want to do? How do I save files from another hard drive to the new one? I have to reformat the old one as it was not set up correctly. The drive I have is Seagate but not specifically for MAC, so I have to format it.. never have done this before. Don't know the jargon. I read that Time Machine will back up automatically but I want to take files from the old drive to the new one. Do I have to take them to the computer first and then to the new drive? I need more memory on my computer. It's way too cluttered and congested. HELP!

Whoa! Slow donw. TRhere's a lot here. I would suggest you buy a good book on computers in general or macs in particular, one is "OSX the missing manual".
What does it mean to "partition" the external hard drive?
It means you take one large drive and make it into more than one volume. This means that it might show up as 2,3 or 4 inde[pendenmt drives. Each one could have, for example, a different operating system on it. Its a good thing to do if you want to use a drive for several purposes
Is it something I want to do?
beats me, you didnt way what you're trying to accomplish. Sorta like sking "should i turn left?" Depends on where you want to go.
How do I save files from another hard drive to the new one?
See advice n book above. Copy them in finder. Copy them in unix. Use a backup or sync utility. No different from Windows in that respect.

Hook it up. Run disk utility. Partition 1 or more partions. GUID map. Format each partition Mac OS extended, Journaled. for more, read book, above. Seriously - we could give you more tips, but you really should learn enough to be comnfident.

I have no idea what you are asking.

What kind of memory and why? RTAM? Hard drive space? Explain. By the time you are done explaining, i suspect you will have ansered your own question.
Good luck,
Have you read the PDF manual for your cmputer?
Have you used a search engine to look for info, for example, in two seconds i got this from google and wikipedia:

Hi Everyone. I have an old Mac Book. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive?Pls.help.

Hi Everyone. I have an old Mac Book with software updated to 10.6.8. I have saved a ton of emails in my inbox 'On My Mac'. There are so many it is slowing down my computer. Where do I find the folder with all the emails so I can cut and paste them to an external hard drive? Pls.help. Tks.

Depending on which email client software you use
the files should be in 'your home folder' library, esp.
if you use Mail application.... ~/Library/Mail
Since you don't specify what mail application,
that would most be associated with the file.
I notice there are some items to the right of your post
where it says "more like this' so that may be worth a
look to see if similar issues were answered. Also, the
Help viewer in your system is a searchable database.
Seems that google also brings up fair information, too.
Do you have a complete bootable clone of your entire
Mac system on an externally enclosed hard disk drive?
Good luck & happy computing!

How can I partition an external hard drive with data in it? When I select the drive, the partition option is grayed out.

I am having a problem partitioning an external hard drive with data in it.
When I select the partition, everything is grayed out. I can't add a a partition for some reason. When I asked this question to other people, they told me to select my partition "io" to do it from there.
As you can see, I can't seem to partition it form there either. I ran the Verify Disk utility but the volume came out okay.
Any ideas as to what the problem would be?
Thanks!
Luis

Select the main hard drive entry (topmost one.) Click on the Partition tab. Shrink the existing partition by grabbing the sizing gadget in the bottom right corner and pushing up until you free up enough space for your second partition. Be sure you do not shrink to less than the space currently occupied by your files. Click on the Add[+] button to create a new partition in the free space. Click on the Apply button and wait until the partitioning is completed.

Partition of External Hard Drive

I am trying to partition an external hard drive into three partitions - one for the time machine backups, one for miscellaneous storage and one for storage of files that I can share with a PC. I was able to partition the drive successfully but all three partitions are in the Mac OS Extended (journaled) format. I understand that I need to change the format of the part I want to share with the PC into FAT but when I click on that drive, I don't have the option. I tried looking under the "erase" tab but the only options are: Mac OS Extended (journaled); Mac OS Extended; Mac OS Extended (case sensitive journaled) and Mac OS Extended (case sensitive). Now, if I look at the entire hard drive (not clicking on one of the partitions), the option is there. I could erase the entire thing using the MS DOS (FAT) option, but I don't want to do that. How can I format only one of the partitions in the MS DOS (FAT) format?

I think it's because of the drive's Partition Map Scheme. In Disk Utility, select the drive in the left side bar. Look at the bottom of the window, and find Partition Map Scheme. If it is Apple Partition Map, you will not be able to format it as MS-DOS (FAT).
The way to fix this is to go to the Partition tab. For Volume Scheme, select 3 Partitions (even if it already is 3 partitions). Click on the Options... button. In the window that opens, select either GUID Partition Table or Master Boot Record. GUID Partition Table would be best for use on the Mac, as long as the PC is OK with it (I'm not sure). Now, when you return to the Partition tab, you should be able to select MS-DOS (FAT) for one partition while keeping the others formatted for Mac.

My whole catalogue was nearly lost due to a failed external hard drive. Professional help recovered photos but I can't find my smart tags. Is it possible they were lost on failed drive?

Hi,
In order to recover the tags/albums, etc, you need to have the catalog db. Since currently you only have images, the organization done in the older catalog is probably lost.
Which version of PSE you have and is there any chance, that you have access to catalog location (default is : %programdata%\adobe\elements organizer\catalogs on Windows and ~/library/app support/adobe/organizer/catalogs on MAC) ?
Thanks

I have an IMAC and I'm running OSX 10.9.2. I'd like to store my Aperture /IMovie Libraries on an external hard drive. In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives. Is this possible? Can I set up a RAID 5 format for redundancy?

I'd like to store my Aperture /IMovie Libraries on an external hard drive.
That is fine and recommended.. use the fastest disk you can afford.. ie Thunderbolt>USB3>FW800>USB2.
In addition, I'd like to partition the external hard drive so that Time Machine can use it to both back up my IMac and the external library drives.
Let me be clear.. you want to partition the one disk.. use it for TM and move your files to the external disk.. and then backup to the same disk.. You can do it.. but that is not a backup.. that is an experiment in how long you can get away with running files and backups on the same disk before you lose everything.. like Russian Roulette.. pull the trigger enough times and laws of probability will do you in.
You must have backups on a different disk .. otherwise it is pointless.
Can I set up a RAID 5 format for redundancy?
No.. you can buy special USB and Thunderbolt external drives that support RAID..
BUT that is still not a backup.. let me show why.. you make a silly move and corrupt your file in aperture.. it is not that rare.
Raid will corrupt all copies of the files.. it is replicated across all disks.
Delete a photo it is deleted across all disks.. you have no recovery.
Alway, always consider RAID system one disk.. backup onto another disk.. and if the photos or movies are at all important to you.. ie your family .. make another copy and store in a relatives house.. There is no such thing as too much redundancy.

Snow Leopard's Startup Disk pref can’t see Yosemite volumes. So the only way to switch from Snow Leopard to Yosemite is to do what Niel mentioned. Doesn't matter whether it's connected by USB or Firewire, although performance via FW would be faster.
Are you saying that Yos/10.10, as a volume located in a mounted external drive won't appear as an option in Snow Leopard's Startup Disc, in Sys Prefs? I've never heard this one before. AFAIK any mounted volume, regardless of OS, should appear there. I would think that, if it appears in the Boot Picker/Startup Manager it would also appear and could be booted to from Snow's Startup Disk. I can't test this myself, since I don't have Yos. Is what you are saying documented somewhere?

Partitioning an external hard drive for Mac and PC

I want to partition an external hard drive (3TB) into 3 even partitions. I want to use one for PC storage, one for Mac storage and the last for Mac backup. Is this possible and how do I do it?

Drive Partition and Format
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. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply 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 Security 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. Re-partition the drive to create the three partitions. The one you wish to use on a PC you should format MSDOS (FAT).
When you connect the drive to your PC it should have no problem reading the partition set up for a PC. Now while on the PC you may wish to consider reformatting that partition using ExFAT (if supported on your PC.) This format is more compatible with both OS X and NTSF supporting long file names and other FAT filesystem irregularities.

How can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

Hello everyone, how can I partition my external hard drive supporting mac OS in one partition and windows OS in another?

OK. Start with:
1. Open Disk Utility in your Utilities folder.

How do I partition my external hard drive without losing data?

How do I partition my external hard drive without losing the data already on it? I've been using it with Time Machine on my old computer, but want to use it as a regular drag-and-drop type back up on my new computer. Is there any way to basically split the hard drive so I can still access the Time Machine backups on my old computer, but also be able to use it with my new mac? Thanks!

If you reformat the drive all data is lost.
The only way to save the data is to copy it somewhere else during the reformat.
Drag & drop will not backup things correctly.
I suggest you set up partition for each Mac and then point Time Machine to each of the partition for each of the Macs.
