Installed leopard, now secondary internal drive repeatedly dismounts itself

After searching the discussions, I'm now resorting to posting for help for the first time in about a decade of owning macs.
I finally upgraded to leopard and now my secondary internal drive keeps dismounting (disappearing). I get the same error message that I'd get if an external drive had been disconnected without first dragging it to the trash. When I restart the drive reappears but then decided to unmount at some random time afterward.
I'm about to reset the SMU. I've already reset the PRAM and run Disk Warrior. S.M.A.R.T. status is verified on both my main and secondary drives. Disk Utility shows no problems. I've backed up all my files and am thinking I should just replace the drive. I'm worried that I'll just run into the same issue though and wind up spending money on a new drive that I don't need.
Any ideas?
Thanks!
James

I have the same problem randomly although I don't get an error message. One time it has unmounted after startup otherwise it fails to mount at startup. I had been leaving a CD in the machine at startup and wondered if this could be the reason. I started removing the CD prior to shutdown and the problem has pretty much gone away, but not completely.

Install Leopard on an External Drive on a Snow Leopard Mac Book Pro

Hi
I have a MBP 17/CTO 2.66GHz i7, which came installed with Snow Leopard.
I've used boot camp to install Windows 7.
I've attempted to install Leopard 10.5.4 on an external drive.
The steps I've taken:
1 - Connected my WD Passport on the Firewire Port
2 - Partitioned the drive. The first partition is 100GB, Mac OS/X Extended (journal) and I've selected the GUID Partition Scheme
3 - Inserted the Mac OS/X Leopard DVD, and followed the instructions to restart
4 - On restart I have three options. Mac OS, Windows and Install Mac OS\X
5 - I select Install Mac OS\X.
6 - The disc spins for a few moments and then the laptop freezes
Beware of the following issue:
1 - On restart more often than not, the DISC will spin and then the laptop will freeze.
2 - To overcome this, restarting pressing the ALT (option) Key.
3 - You should see your boot options. If you do not see "Install Mac OS\X", then eject and reinsert the disc.
The question maybe why would I want to have an Leopard Installation when I have Snow Leopard. The software I develop has thrown up a number of differences between Leopard and Snow Leopard, hence I need both OS's to support my software.
I mentioned this to the Apple Store before I purchased my machine. They put me through to a senior technician at Apple Care, who told me it would be possible to have the set up I am after; and to contact Apple Care if I ran into any difficulties.
After I received my laptop and ran into the problems I described above I contacted Apple Care, only to be told by a senior technician that it should be possible to install Leopard on an external drive, but Apple Care cannot provide any support or assistance.
I really do like the laptop and would much rather not return the laptop; but I really do need the setup described.
Anyway I have tried a number of different approaches:
1 - Having no partitions (so just the single partition)
2 - Trying all three Partition Schemes:
- GUILD Partition Table
- Apple Partition Map
- Master Boot Record
All resulting in the same problem.
I can confirm the external drive does appear as bootable in disc info.
My guess is one of the following is preventing the install:
1 - It is simply not possible to install an earlier version of Mac OS\X than 10.6 on the laptop I have, even if I tried to install on an external drive. This restriction is built into some hardware confirguration. So even if I wiped the internal hard drive or added a new partition to the internal hard drive, I would not be able to install 10.5.4. I say this may be a reason as the second technician told me the CPU has built into it a process which prevents installing older versions of Mac OS/X, but that it should NOT restrict installation on an external harddrive.
2 - When trying to install Mac OS/X, a search is carried out for an external drive which has the correct format. For some reason it may be that this search is not finding my external drive?
I'm a little stuck here and quite disapointed that the support promised by Apple Care for assistance in setting this up, is now not forth coming.
Any help or suggestions would be appreciated, as ideally I would prefer to keep and not return the laptop, it's a beautiful piece of machinery.
Cheers
Parmy

The mystery continues...
I have an older MBP (2.33 GHz Intel Core Duo) which came installed with Tiger. I can confirm I purchased a genuine copy of Leopard (10.5.4) from the Apple Store and it’s not an OEM version. I installed 10.5.4 without a hitch on my old MBP internal drive. It is the only OS installed on my old MBP.
Using my older MBP (which through software updates is now running 10.5.7), I managed to install 10.5.4 onto my external HD (WD My Passport Studio – 640GB FireWire 800).
However; on the final restart, the screen remained grey and 10.5.4 did not boot from the external drive.
I restarted the machine holding down the ALT (option) key, and only two options appeared, Macintosh HD and the Install DVD. I selected the Macintosh HD and opened System Preferences.
In System Preferences --> Startup Disk, I discovered the partition on my external HD which contains 10.5.4. I selected this partition and selected restart.
On restart my MBP displayed a grey screen, and the blue light on my hard drive flashed slowly. I left this for an hour, however; the OS did not start and the screen remained grey.
I then plugged my external HD into my new MBP which I started holding down the ALT key.
To my surprise I found 3 boot options (Macintosh HD, Windows and Leopard). Leopard being the partition on my external drive, which now has 10.5.4 installed.
I selected Leopard, but sadly after 30 minutes, the OS failed to boot.
Although this deviates slightly from this post, I fail to understand the problem here:
1 – Why can’t I boot 10.5.4 on an external drive, from my old MBP? Surely this is not because my old MBP is now running 10.5.7?
2 – Why can I see 10.5.4 as a boot option on my new MBP but not on my old MBP when I start the MBP holding down the ALT key?
I doubt there is a problem with my external drive, as it seems to read, write, etc... in all normal cases.
Whilst it definitely appears that I won’t be able to boot 10.5.4 on an external drive from my new MBP, I should be able to at least boot it from my old MBP, which would give me the option of installing Snow Leopard and Windows on the internal drive of my old MBP.
Apologies for keeping this post going, but I hope by getting to the bottom of this, it will help other Mac users as well.
I’ve run out of ideas of things to try, so I will give Apple Care another call in the morning, and will report back.
Any suggestions of other things I can try?
Cheers

Can I install Leopard on an external drive to run my computer?

Since it seems my hard drive has totally bit the dust, can I install Leopard on the external drive I use for Time Machine, and run my desktop from that drive? Could I run it from an external drive totally dedicated to Leopard? I am buying a new desktop soon, but I need info off of this machine. Can I plug in my Time Machine drive to my laptop and be able to use it without losing data?

Thanks so much.
Youa re welcome!
I figured I would have to use a second drive. At least when I get my new desktop I will have a drive for Time Machine for both desktop and laptop.
If you really plan to keep the laptop around after you get your desktop, I would recommend replacing its internal hard drive. While running your laptop off an external is possible, it should be considered a stopgap measure. i wouldn't do it on a permanent basis. For one, as you'll find out, it's quite a bit slower than when using the internal drive.

Install Leopard on a hard drive

Is it possible to install Leopard on any hard drive that is formatted to +Mac OS Extended (Journaled)+

No problem.
Insert DVD, boot holding down "C" key and when prompted select the appropriate HD.

Installing Leopard and new internal hard drive at same time, best plan?

Ok so basically the title explains what I need to do. I am currently travelling in Europe, and returning home to New York on Tuesday night. I have a new hitachi 250gb HD and will have Leopard waiting for me at home when I arrive, and will get right to doing this installation. I am writing on the discussion boards here because I am hoping the users here can give me their opinions on what is the best plan of action to do this whole install?
So what I was thinking was, I should remove the hard drive that's already inside, put it into an external enclosure. Then, put my new blank 250gb hard drive into the macbook pro, close up the computer, then put the Leopard OSX install disk, and do a completely fresh install of Leopard. Then, after installing (or during installing?) I should run the migration assistant program to get all my files and settings etc. transferred over to the new internal hard drive with Leopard on it, from the old hard drive that will be plugged in from an enclosure as an external drive.
Will this plan have any problems that I am not aware of? Is there a better process for doing this task? Any advice will be greatly appreciated! I am anxious to get my new hard drive into the computer because my 160gb is filling up, and dying so badly to use the new Leopard!!

You could also put the new disk in the external enclosure, partition it using disk utility. Then make a clone of your current hard disk to the new external one using the restore feature in disk utility. Boot from the external disk and Install Leopard as an upgrade keeping all your files and setting. check everything is all running how I should and swap drives over. That's another option for you.

Hi, I'm running my macbook from an external hard drive (Os yosemite) due to bad reinstall of mavericks. It was fine for a while then admin Password stopped working and i tried all ways to retrieve it. I want to install os back onto internal drive.

Due to a bad install of Mavericks, my macbook was just on a loop. I correctly formatted a new external drive and installed Yosemite there and was able to retrieve my files onto the external drive. So for a while I was able to run my mac from the os on the external drive and it was fine. I built up enough courage to clear the internal hard drive. or so i thought. It will no longer recognize my admin password and I can't gain access through my Apple store and iCloud password so I have effectively been locked out. i have tried all suggested ways to deal with that. I can't seem to install the os from my external drive on to the macbook internal drive. My dvd/cd player hasn't worked for a long time so I can't install a snow leopard disc and upgrade from there. I really need help here. thanks

Tried this just now, but it didn't work. I copied it to my internal drive, but if I then selected that file and told it to open in iTunes, it played the one on my external drive.
However, it was possible to play the copied movie in QuickTime Player. I wonder, though, would that approach work with a rented movie? The movie I was using was one I bought from iTunes.

Installing Leopard on an erased drive

I purchased an iMac on eBay. It came with the previous owner's stuff still on it (incl. Tiger). I wanted to do an erase/install of Leopard, and then transfer my files from my previous computer. In the midst of the erase, the power cord accidentally was pulled. When I restarted the computer, the drive was apparently erased, and the installer said that installing 10.5 required the presence of 10.4, which it couldn't find. I inserted the 10.4 install disc, to install that, but the computer won't boot up from that (or any) disc. Even when holding down the "C" key, I only get a gray screen with a folder/question mark icon.
Would appreciate any suggestions as to how to get Leopard installed on this erased drive!

the installer said that installing 10.5 required the presence of 10.4
So these are Leo upgrade disks and not a retail version of Leo?
It appears that your power cord mishap has resulted in an unconfigured HD that is undetectable. This can be an expensive proposition. Folks with Windows installation mishaps have endured the same results. I posted an unofficial solution from Jon Glazerman, which has proven successful for others and it should work for you as well.
Solution
Since the Mac will not boot the DVD, we'll create an Intel Mac-bootable external installer drive.
What You'll Need:
• A working Mac
• An external hard drive you are willing to format (Firewire only was tested)
• Apple's Disk Utility
• Mac OS X Install Disc 1
• An installed copy of NetRestore v3.3x (Freeware)
Procedure - on your working Mac
1. Insert Mac OS X Install Disc 1 into your DVD drive.
2. On your hard drive, open NetRestore Helper (see above section if missing)
3. Make sure the "Create Master Image" tab is highlighted.
4. At the Master Disk prompt, select Mac OS X Install Disc 1.
5. Select the "Read-only compressed" radio button.
6. You may check the boxes below to skip checksumming and post-processing at your discretion.
7. Click the lock icon in the lower-left corner of the NetRestore Helper window and supply your Username and Password. Once successful, you'll be able to click the Create Master Image button.
8. You'll be prompted to name and save your install disk image. The image creation process could take 10-40 minutes depending on your Mac's capabilities. After a successful image is made, you may close NetRestore.
9. Connect and turn on your external hard drive if not done already.
10. Open Disk Utility and select your external hard drive in the left column display. In the lower right, look for Partition Scheme. If this says "GUID Partition Table", skip to 15.
Important: To make this external drive bootable on an Intel Mac, we need to make sure it's the proper format. You are about to delete the contents of your external drive. You may wish to create a backup before proceeding.
11. Make certain your external hard drive is selected, and click on the "Partition" tab just below your button bar.
12. Name your external hard drive and select Mac OS Extended (Journaled) format.
13. Toward the bottom of the window, click the "Options..." button. Select "GUID Partition Table" and click OK.
14. Click the Partition button and confirm.
15. Select the Restore tab and drag the disk image you created with NetRestore onto it. Or you may click the Image... button to locate the image of your install disk.
16. Drag your external hard drive partition from the left column into the Destination field. You may optionally check the Erase Destination box and then click the Restore button.
Note: If you have still have the installer disk image open in another application (such as the Finder) you may receive an error from Disk Utility until this image is closed in all other applications.
After verification, you may close Disk Utility.
17. Using the Finder, check to make sure your external hard disk file layout resembles your Mac OS X Install Disc 1 DVD. Big discrepancies may indicate a problem in creating the image or restoring the image.
18. Dismount the external hard drive from your working Mac.
Procedure - on your Core 2 Duo Mac
19. Connect the external hard drive cable to the non-booting Core 2 Duo Mac. You'll want the Mac turned off for booting purposes. Turn on your external hard drive.
20. Turn on your Core 2 Duo Mac while holding the option key. The gray screen will be blank for several seconds, followed by an icon for your external hard drive. You should be able to click on this icon and begin the Mac OS X install process. It may not work on the first try, so you may need to power off the system and try again. Also try a USB keyboard and mouse instead of Bluetooth.
Note: If the Max OS X installer runs, but is having trouble identifying your internal hard drive, launch the Disk Utility first and format it using the GUID Partition Table before continuing.
At this point, your Mac should be able to read your second install disk from the DVD drive without issue.
I really hope this fix works for you and you can start enjoying your new Mac again. Again, there may be other methods (for example, booting the install DVD from an external firewire DVD drive) but whatever the case, good luck and thanks for reading.

How do I install leopard on an external drive

I have been unable to install snow leopard on my external drive, when I put the install disc in the drive on the iMAC, it shows up on the desktop, but i cannot get it to install on the external drive, the iMAC has Lion installed.

I'd like an answer to the original question, too. I have a brand new Intel iMac which came preloaded with Lion. I'd like to install Snow Leopard on an external hard drive for a variety of reasons. I would rather NOT erase the internal hard drive of the iMac, if possible. Of course, I get this same message that, "You cannot install Snow Leopard on this machine running Lion" more or less. Does anyone have a method of faking out the installer so it will install Snow Leopard onto an external hard drive even though the Mac is running Lion?

Install leopard on an external drive?

Hi I was wondering if I can do a clean install of leopard on a usb external drive.
I originally did an upgrade install on my imac, but would like to play around with a clean install on an external. And if the setup seems faster would like to migrate it back to my internal. Just wondering if this would be possible? Thanks

Yes you can I have a clone of my internal drive with leopard using carbon copy cloner and it is bootable

How to install windows on separate internal drive?

Hello,
I've been at this problem for a few days and need some help if anyone has a clue.
I have a late 2008 macbook pro 15". I've taken out my optical drive to install a SSD so that I can run both the existing internal drive and SSD as a DIY Fusion Drive. I'm in need of Windows now and tried to partition the existing fusion drive like I would normally do to install bootcamp. This doesn't seem to work. I then unfused the fusion drive back to two separate hard drives with the OS X Yosemite on the SSD and I want to install Windows on the existing Hard Drive. I've created a bootable Windows USB through the Bootcamp Assistance, but when it comes time to install the Windows install menu does not pop up. I would get a blank black screen which then I would have to restart and boot up into my OS X. In the OS X I can see that a bootcamp drive has been created, but it doesn't show up when I hold Option during the reboot.
If anyone knows what's going one, please let me know!
Thank you!

Rather easy enough to do. People install XP and Vista all the time on 2, 3rd or 4th drive in Mac Pro. I know Vista 64-bit on Mac Pro has best support for addressing RAM and drivers.

Installing LaCie DVD±RW Internal Drive with LightScribe 16x E-IDE with DL

Have just bought the LaCie DVD±RW Internal Drive with LightScribe 16x E-IDE with Double Layer for an incredible price if $44.99. Geeesh, why are they so cheap these days? I did researched this with LaCie customer/tech services and they indicated once the face plate is removed it will install easily into my PM G5 Dual 2.5GHz (Rev B model).
Has anyone else installed this and if so are there any issues to be aware of as part of the install process - oh, and did it work AOK ?
Thanks for any insights and/or feedback on this. I should be getting the LaCie burner next week sometime.

FYI...
OK - so I received my LaCie - LaCie DL DVD±RW Internal Drive with LightScribe E-IDE, with Double Layer today. I thought I'd post my install experience before it all faded into the murky past. ;-)) I do this in order to help myself and for others who may wander down this install path. There are a few minor gotchas that if known ahead of time will make the install easier and less thought provoking for having to make decisions on how best to proceed.
Let me say up front, the install was successful, Apple's DVD SuperDrive device design is superb in that it allows easy removal in a dimensionally constrained space and the new LaCie device is now fully operational. I've played a DVD movie, it's compatible with the .Mac Backup 3 program after loading LaCie's software and my PM G5 Dual 2.5GHz (Rev B) now recognizes the device as a DL DVD burner (Vendor Supported). I've yet to use the LightScribe Labeler software, although I've installed it all from the supplied discs and latest updates from LaCie Support web site at http://www.lacie.com/support/drivers and select DVD from the drop down menu selection. I'm very pleased with this LaCie device at this moment.
Here's the install process step by step
1. First power off and disconnect all external devices from the PM.
2. Get your wrist strap on and ground yourself to PM casing.
3. Lay PM on its side and remove metal side panel and remove clear plastic panel.
4. Rotate both plastic latches that hold the SuperDrive in place.
5. Disconnect the SuperDrive's flat wire ribbon from Motherboard - it has a convenient handle for pulling it straight up and off. Once disconnected, push it thru the opening to where the SuperDrive casing is located. This will be more obvious when you are actually doing this.
6. Open the SuperDrive's Alu door by pressing lightly on it and sliding it down.
7. With Alu door open use a finger nail to engage a portion of the SuperDrive's tray opening and push up and towards yourself and at same time with other hand pull up the rear most portion of the SuperDrive's casing. The drive should slowly slide away from its feet slots much like for the HDs. Slowly remove the SuperDrive and before it is fully out remove its power connector and then the flat wire ribbon from rear of SuperDrive. The SuperDrive can now be completely removed. Note that on my SuperDrive the flat wire ribbon was attached to SuperDrive's casing with a grey two-sided sticky pad. Remove the ribbon carefully from this and then remove the sticky gray pad and affix it to the same place on the LaCie device. Rememeber the wire ribbon's orientation as you will need to re-install this a little later.
8. Remove the 4 black screw feet from the SuperDrive's lower surface. You will need a torx screw driver and may have to begin by losening them with pliers. Take these and screw them into the same spots on the base of the LaCie device.
9. Remove the stainless steel face plate from the SuperDrive - ply up the end wraps and it will slide and pull off easily. Place this onto the LaCie device.
10. Put the SuperDrive aside as you're all done with it now,
11. Press the tray release button on the LaCie device and pull off its plastic face plate - comes of easily.
12. This next step is a bit tricky, a bit time consuming and some care is needed. The LaCie tray eject button needs to be removed (you will notice on Apple's SuperDrive it's also missing, and there's a good reason for this). Use a small screw driver and pry up the right side (looking straight at the front surface of the LaCie device) of the button. It will come up and rotate to left some. The button is held on by a small plastic C-shape tab. Rotate the button to left until it comes off. This button cannot be left attached as when the LaCie device is installed the PM's Alu door opening mechanism will contact and interfer with the button and engage and press it down. Obviously this will make the LaCie device (and of course the removed Apple SuperDrive) think the tray needs opening.
13. Leave the jumper on the LaCie device in its default "Master" location. This should be the right-most two-pin position looking at the rear of the LaCie device.
14. Almost there - attach power connector and flat wire ribbon to rear of LaCie device and press the flat wire ribbon onto the sticky grey pad and slide the LaCie device into its holding slots by aligning those black screw feet with the slots. You may need to guide the other end of the wire ribbon thru the lower opening to the motherboard. Once the LaCie is in place connect the wire ribbon to the motherboard.
14. Relatch the plastic levers to secure the LaCie device firmly in place.
15. All done - so replace the plastic and metal side panel, reconnects things up and power on the PM. Go straight to the ASP and make sure the LaCie device is recognized and all the info is being displayed correctly. It will show Burn Supprt of Yes (Unsupported). Don't worry, once you install the included LaCie software is will show "Yes (Vendor Supported)".
Total time taken was around 2 hrs as I had to pause several times trying to figure out how to remove the SuperDrive with care and without any instructions to go by.
My LaCie - LaCie DL DVD±RW Internal Drive with LightScribe E-IDE, with Double Layer cost me $45 from Buy.com and it does come with two disc blanks - a Verbatim LightScribe 1x-52x CD-R 700MB and a Verbatim 16x SL DVD+R.
I recorded all the gory details from the LaCie device before installing it. Here's that info.

Installing windows on second internal drive

I've just started taking a course in datamatics, and therefore I need to get my hands on a windows computer for class. I currently own a 13" 2011 Ultimo MacBook Pro
I have previously changed my old HDD with a SDD, for better performance and with great results. Instead of buying a new computer as resolution, i figured i can buy second SSD and a SSD-adapter to replace my super-/disc- drive(*). Basically i thought, that I could install the new SSD, and download Windows 8.1 from Microsoft's online store, and install that on the new SSD. But i am beginning to worry, if I am going to run into any complications with the installation of Windows. If I download windows on my "old" SSD, will it not be able to install on the new one? Or is Bootcamp just gonna consider the two SSD's as one, and not have a problem transferring the installation package between the two of them?
*The SSD-adaptor included an external superdrive-casing that ultimately turn my disc drive into an USB-device. check the link:
http://www.ebay.com/itm/221251367597?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m149 7.l2648

There are a few Macs which come with a second disk (SSD/HDD). These are Mac mini and MacPro. Bootcamp Assistant understand the configuration of the Mac and possible combinations. If you replace the Optical drive and use an Optibay adapter and an SSD instead, Bootcamp assistant will not use the second SSD to install windows, because for that specific Mac model, the original configuration is a single HDD/SSD, not two.
The second issue with this configuration is due to the SSD and SATA speed differences between the Optical drive and SSDs. SATA III SSDs do not work well in the Optibay. This causes a lot of pain during Bootcamp/Windows installation.
The only solution that works is by using an SSD/HDD in the main bay (without a second drive installed. Leave the optical drive in instead, because most Macs with an Optical drive require a DVD with few exceptions as documented in Boot Camp 5.1: Frequently asked questions - the ISO question) and then moving it to the Optibay, and installing a second SSD in the main bay. Please see Unable to Install Windows 8 on secondary Hard Disk for details.
I suggest leaving the original configuration intact, install Bootcamp, and then move the disk containing Bootcamp to Optibay. Please be aware that SATA speed issues should be addressed before an SSD is bought. There are few SSDs that can work with SATA I/2/3 (Samsung 840 Pro being one, but not the EVO line, which has its own firmware challenges).
In the case of Mac mini with Fusion drives (or two HDDs), Bootcamp will only address the second drive, and will not install properly on the SSD/first HDD. The workaround to use the SSD requires buying Winclone.
In the case of MacPro, the only drive which should be in the MacPro (Generation 1) is the designated drive, all other drives should be removed prior to Windows installation. Please see Re: How to install Windows 7 on extra Internal Disk.

Installing Leopard from USB flash drive

Basically i need to install Leopard from a USB flash drive on my Macbook, but i will sum up my issue: (I'm afraid i'm not a computer-"geek", so bear with me when i try to explain the issue :-))
My macbook hdd recently died on me, so put in a new, clean hdd. I now need to install Leopard on the new hdd from a DMG-file.
So, i have an 8GB USB flash drive and DMG-file of Leopard.
I formatted the USB flash drive to NTFS, and copied the 6+GB DMG-file onto the flash drive.
I tried booting from the flash drive by holding down the option key, but a blank screen shows up with a mouse pointer. There is no Flash drive or install icon to select.
Can anyone tell me, what i'm doing wrong?

Hi Dweepe;
On top of everything else the other posters pointed out, I would suggest that formatting the USB flash drive to NTFS is not doing you any favors either. NTFS is a propriety file system from Microsoft which the Mac can only read with special software install.
My suggestion is to replace your optical drive. A new one can probably be purchased for much less then the problems you are creating for yourself in your attempts to work around replacing it.

Installing Leopard on new hard drive

Want to replace HD on my dual 1.8 G5.
How do I go about starting, formatting and installing Leopard on a new blank drive.
My old drive is backed up on an external using TimeMachine.
After install I plan to pick and choose what to replace from TimeMachine.
Thanks for any help.

First:
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 dropdown 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 volume(s) mount on the Desktop.
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.
Quit DU and return to the installer. Have your TM backup drive already connected. When installing you will be provided the opportunity to restore an old system from a TM backup. I believe this will appear after completing the Setup Assistant.
If your old drive is still functional then you can put it in an external enclosure, boot from it and clone it to the new drive after the new drive has been prepped per the above.
