What hard drives will allow me to boot from them on power PC and Intel?
I'm trying to get a setup together to make use of my old versions of OS X. I'm planning to partition a hard drive and install each version of OSX on its own separate partition and possibly OS 9 as well.
That part seems to be the easiest to figure out, but the hard part is finding a drive that would do both. I was considering a portable USB drive like this http://www.seagate.com/www/en-us/products/external/freeagent/freeagent_go/
But I'm not sure if it would boot to a Power PC machine.
This may be over simplifying it but PPC Macs won't boot from USB, just Firewire, hence the 'need Firewire' part of Niel's statement. PPCs also have to have their drives partitioned with Apple Partition Map in order to be bootable. Intels on the other hand will require you to use GUI partition map when installing an OS, but then that will make the drive unbootable on a PPC. Although Intels require you install to GUI, I believe if you have a drive with APM and then clone the Intel version of the OS to the APM drive it will actually work as a bootable drive for the Intel Mac. So the bottom line is, you'll need to have the drive partitioned with APM to make it bootable with the PPC, and you can slip an Intel version of the OS onto the drive too.
Note, by the way, that even though you may have OS9 on that drive it still won't work with your Intel Mac or any Mac that won't boot OS9 natively. Nor will the Intel Mac be able to use it as Classic, nor will it work as Classic with anything higher than Tiger.

What hard drive will work in my on a h81420t
what are the harddrives that works in my h81420t
For some reason, the product model specified returned 36 results on HP's support site. It looks like it may have one too many characters in it. What is the product number?
For the most part, just about any HDD should work in the system. I wouldn't necessarily recommend a 2TB or larger HDD as some older systems can't boot from a 2TB HDD (using one as a secondary drive wouldn't be an issue).

I'm concerned that my iMac, purchased 5 years ago, is about the crash and I can't back up my files and programs to an external hard drive via Time Machine because the computer freezes after only a couple hundred MB and gets nowhere near the required amount.
How can I save these files and programs if the computer hard drive fails or has to be replaced without the backup being able to be done? I need to do something quickly, but I'm not sure what I can or should be doing.Get an external hard drive, some good ones that I like are the OWC, http://www.macsales.com Mercury Elite Pro drives...they are very good and reasonably priced.
Get the drive, connect via USB or FireWire, then use Disk Utility to format the new drive as Mac OS X Extended (Journaled), and then use Disk Utility to Restore the current drive to the new drive. Restore actually clones the drive so you will have a bootable backup on the external drive.
After you have formatted and named the external drive, click Restore in the main Disk Utility window, drag the name of the old hard drive to the Source box, and drag the name of the new external drive to the Destination box. DU will make an exact clone of the internal drive on the external drive.
That clone will be a complete backup of the operating system and all of your data.
You can test it by restarting the iMac and hold the Option key. That will give you a grey screen showing all bootable drives. Just click the external drive, then click the upward pointing arrow under it and the iMac will boot from that drive. -
New hard drive in, not recognized when boot from DVD
Well, I installed my new Seagate ST3750640AS, 750 GB Baracuda and when I boot from the Tiger install DVD, there is no Hard Drive listed. What could have gone wrong. I have an early model G5 iMac.
Are you sure the cable is connected? Look at the [DIY|http://www.apple.com/support/manuals/imac> for replacing your drive and see if there's anything you may have missed.

I Mini with an i7 processor. I would like to use Boot Camp to install windows based CAD software on my MAC. Would it be better to use a plugin external hard drive to load my software on and if so what hard drive would you recommend?
Thank you for your quick response. I can then use a ZIP drive for data storage. I want to keep as much of my hard drive free of data as possible.

Time Machine will not let me restore from backups after June, 2013. I can see the files on the external hard drive but Time Machine skips all of them and goes back to June, 2013. Does anyone have any idea what the problem is?

telling me to buy a new router is NOT a solution.
And why not? Apple is selling these things like BigMacs. They can't make enough of them. You've been suffering since May because you refuse to get a decent router.
Can you imagine if a company that makes a refrigerator told me that I needed to upgrade my electrical system to rectify a problem with their device? What kind of response IS that?!?!
What if the problem with their device is that it requires a new-fangled "grounded" outlet and your circa 1890 house doesn't have grounded outlets. Would you refuse to purchase a $ 25 adapter on principle? -
my laptop will not boot up from the storage hard drive but if i remove it from the laptop and connect it as portable hard drive my laptop boot up normal?
Do you have a compatible OSX installed on this 'storage' HDD? If not, it will not boot your MBP.

I'm usually good at backing up my photos and documents, but the last 2 months of pictures and videos are on there and not backed up anywhere. I'm heartbroken.
"What are the odds that my hard drive will be salvageable?"
Very very good, it's all sealed and only a large electrical surge or dropping it while running could do some damage.
Take it and use a SATA to USB adapter you can get online for $12-$40 and hook it right up to the new Mac and use Setup Assistant or Migration Assistant to transfer files.
OR you can access the drive directly and on a PC with MacDrive installed.
However the Mac itself is likley a goner. -
I recently updated my 20-inch, Mid 2007 iMac with the latest OS 10.8.5 now my external hard drives will not show up. They show up when I boot them up on a machine running and earlier OS. Is there a fix for this?
Can you see them in Disk Utility?
If so, can you select and Mount them?
If not, disconnect them, reset the iMac's SMC and then reconnect them.
Intel-based Macs: Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
If you still can not see them, connect them back up to the iMac running the older OS, open Disk Utility and look to see how they are partitioned and formatted. -
External hard drive will not partition correctly
This is a somewhat long post, but the point is this: I have a new 1TB Fantom GreenDrive (attached via USB) which I cannot partition the way that I want to. I want to allocate 300G for a Time Machine backup partition and the remainder as a partition for everything else. For some reason, I'm only able to partition the drive so that it has two equal-size partitions. While this isn't terrible (the 300G figure was somewhat arbitrary), I'm curious to see if anyone knows what's going on here. As part of my tale, I list three "mysteries" that have really stumped me.
For at least a year now, I've had two external USB drives attached to my machine through a hub. One (a Fantom Titanium-II 500G drive) was for Time Machine, and the other (a LaCie 150G drive) was for other files. These drives were almost always connected to my machine, and they were almost always powered on. About three weeks ago, the Time Machine drive started unmounting, seemingly randomly, from the computer. When I tried to verify it in Disk Utility, it gave me an error, and the drive would again unmount. At the same time, I started having problems with the LaCie drive - when I plugged it in, the Mac gave me a message saying that the drive wasn't working properly and that I had to back up everything on it.
This all seemed too coincidental to me, and so is the first mystery of my saga. However, I saw the GreenDrive on sale and decided to pick one up, rather than trying to fix the two drives. When I connected the GreenDrive to the computer, it was formatted at NTSF. When I tried to format it as Mac OS Extended (Journaled), Disk Utility gave me an error.
If I booted the Mac into Windows, I could format the drive again as NTSF, and it would work fine. When I went back into the Mac side, it worked there, too (that is, I could read from it and write to it). Also, I could use Disk Utility to format the drive as MS-DOS (FAT). Of course, I needed to format the drive for the Mac so that it would work for Time Machine.
When I went into the Time Machine preference pane and selected the GreenDrive for Backup (which was still formatted as MS-DOS (FAT) at the time), and did the erasing from within Time Machine, I was able to get the drive formatted as one large Mac OS formatted partition. Why I was able to successfully format it from Time Machine, but not from Disk Utility (which I believe is what Time Machine uses for the erasing, anyway) is the second mystery.
So, now I had a 1TB hard drive set up a single partition. I still wanted to divide it in two. However, when I tried using Disk Utility to partition it the way I wanted, I got an error saying the partition failed. Just as a test, I tried partitioning as two equal-size partitions, and this worked. Why it would let me partition in this configuration, and not the way I wanted, is the third and final mystery.
In the end, I'm almost where I want to be. I had to spend a little bit of money, but I have more total storage space available, and it seems to be working fine. Also, I was able to format the LaCie drive, and it seems to be working well, so it wasn't a total loss. Still, any answers you guys can provide would be greatly appreciated.
<Edited by Moderator>Be sure your drive is initially partitioned into one single volume. Then format the volume for Mac OS Extended. Once that's done re-partition the drive into two volumes (if that's what you desire) then resize them as you want. How you do the resizing may be important. Usually the larger volume is the first or top volume. Select it by clicking on its rectangle in the sizing gadget. Then in the Size field enter the size you want. That should result in the first volume being resized to what you want and the second volume automatically resizes accordingly.
Here's how I suggest doing it:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder. If you need to reformat your startup volume, then you must boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger or Leopard.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Set the number of partitions from the drop down menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (only required for Intel Macs) 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. -
Mb pro running like garbage with 10.8.2 tried a reinstall of osx from recovery utility now the utility says my hard drive is ok but wont boot into it keeps booting me back into recovery tried restart option to select disk tried using the select startup disk from recovery, gives a message asking if i really want to boot to it and in that message is the only rime it shows a question mark on the drive dont know what to do cant find similar issue
Your rushing and not making much sense.
Your machine was running like garbage, so you tried to reinstall 10.8---did you do this or not?
Disk Utility says your drive is ok, that's good.
But when you boot it keeps booting Recovery HD, so perhaps the firmware has made a mistake, it can forget.
You held the option key down to boot into Startup Manager, why didn't you select OS X for the boot volume?
When you get into OS X you change the Startup Disk in System Preferences, that should take care of the Flashing Question mark issue.
attemtping to ireinstall osx from recovery partition bar is full on install screen, but im now at -6hours remaining
So now your reinstalling OS X like you set out to do before, it does take some time as it has to download from Apple's servers.
If your Internet connection is slow and/or Wifi is slow then it will take awhile.
So you should have the Flashing Question Mark and Reinstall Only OS X covered.
You should be able to boot the machine, but your performance issues may be something else and still remain.

Any steps or changes I need to do in order to partition my hard drive?
An error message keeps popping up saying "Couldn’t modify partition map because file system verification failed."Do what? Backup? This will get you started.
Basic Backup
Get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
Carbon Copy Cloner
Data Backup
Deja Vu
SuperDuper!
Synk Pro
Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files.
Although you can buy a complete external drive system, you can also put one together if you are so inclined. It's relatively easy and only requires a Phillips head screwdriver (typically.) You can purchase hard drives separately. This gives you an opportunity to shop for the best prices on a hard drive of your choice. Reliable brands include Seagate, Hitachi, Western Digital, Toshiba, and Fujitsu. You can find reviews and benchmarks on many drives at Storage Review.
Enclosures for FireWire and USB are readily available. You can find only FireWire enclosures, only USB enclosures, and enclosures that feature multiple ports. I would stress getting enclosures that use the Oxford chipsets especially for Firewire drives (911, 921, 922, for example.) You can find enclosures at places such as;
Cool Drives
OWC
WiebeTech
Firewire Direct
California Drives
NewEgg
All you need do is remove a case cover, mount the hard drive in the enclosure and connect the cables, then re-attach the case cover. Usually the only tool required is a small or medium Phillips screwdriver.
Once you have a backup then you will need to do the following:
Drive Preparation
1. Boot from your OS X Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, 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 or more. 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 Partition button and wait until the process has completed.
4. Quit DU when the process is completed to return to the installer. Install OS X on the first volume if you created more than one.
NOTE: Do not make more than one partition if you intend to use Boot Camp Assistant to create a Windows partition. -
HT4818 Boot from laptop's Windows Hard Drive in Mac Pro via Boot Camp
I have a work laptop that is on Windows 7. It's a work hard drive so I don't want to mess with it (particularly as it's encrypted). I basically want to use it on my Mac Pro rather than my piece of junk standard issue laptop when I'm working from home.
What I would like to do is pull the drive out, put it in my Mac Pro and boot from it using Boot Camp. Guidance I've seen so far talks about not being able to use an external drive but having to partition an internal drive. However, if I've got everything on a separate drive (i.e. my laptop's drive), will this work?
Thanks!Thanks for the quick (and no nonsense) response!

I use Time Machine to back up my entire computer with my external hard drive. I am getting a brand new iMac this month and was wondering what is the process of using this back up to restore my new computer exactly how my old computer was? I want to make sure I will still have various important files on my new computer, like my songs in iTunes, my photos in iPhoto, etc, etc. Thanks so much in advance!
Welcome to the Apple Support Communities
When you turn on the new iMac for the first time, Setup Assistant will ask you to restore a backup, so connect the external disk and follow steps to restore all your files to your new iMac. Your new Mac will have the same settings and programs as your old computer.
In other cases, I would recommend to restore the whole backup without using Migration Assistant or Setup Assistant, but a Late 2012 iMac uses a special OS X build, so the OS X version that you're using on your old Mac won't work on the new one.
