Disk format GPT and Apple Partition Map Upgrade questions

I was told that switching to the new computer with snow leopard that I would need to reformat my drives from my G5 to GPT (GUID Partition Table) from Apple Partition Map (APM) to get time machine to work (see http://discussions.apple.com/thread.jspa?threadID=2706634&tstart=0)
<<Intel Macs boot to either, but PPC Macs only boot to APM. Intel Mac software (OS) installer only want to install and update to GPT, so if you want to use existing drives to install OS X SL to, you will need to reformat the drive.>>
Disk utility is only giving me Mac OS Extended options, which I thought was my drive format already. So what do I do now? do I erase those drives or what? I'd rather not if I don't need to.

Hi-
The Erase window only offers the formatting scheme.
The Partition Tab offers the selection of GPT or APM partitioning scheme.
You don't have to partition beyond one partition if you don't want to.
Just make sure GPT is selected and the apply.

Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition

just bough OSX Mountain Lion, my laptop operating with v10.6.8. Can't install OSX Mountain Lion, on the disk selection screen i cant select the Macintosh HD to install OSX giving a message (This disk cannot be used to start up your computer).only have one disk to select and my partition map scheme is GUID partition table. 24.44gb disk available.

Verify your computer can run Mountain Lion:
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion - System Requirements
       Macs that can be upgraded to OS X Mountain Lion
         1. iMac (Mid 2007 or newer) - Model Identifier 7,1 or later
         2. MacBook (Late 2008 Aluminum, or Early 2009 or newer) - Model Identifier 5,1 or later
         3. MacBook Pro (Mid/Late 2007 or newer) - Model Identifier 3,1 or later
         4. MacBook Air (Late 2008 or newer) - Model Identifier 2,1 or later
         5. Mac mini (Early 2009 or newer) - Model Identifier 3,1 or later
         6. Mac Pro (Early 2008 or newer) - Model Identifier 3,1 or later
         7. Xserve (Early 2009) - Model Identifier 3,1 or later
To find the model identifier open System Profiler in the Utilities folder. It's displayed in the panel on the right.
Open Disk Utility and verify the drive is partitioned using GUID and formatted Mac OS Extended, Journaled. If it is then do this:
Repair the Hard Drive and Permissions
Boot from your Snow Leopard 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. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Now try installing Mountain Lion.

Can I keep my Lightroom 3 catalog on a PowerMac hard drive with Apple Partition Map

I want to keep my LR3 catalog on a HD in my Power Mac (Intel chip) that I had formatted and used to store my pre-LR3 photo folders on my G5 tower. The 1TB drive is half full, and was formatted as an Apple Partition Map. On swapping the drive into an empty bay in my Power Mac, I can open photos saved on the drive, although I can't seem to rename them. I created my brand new LR3 catalog on the drive as well, but haven't done anything other than import the LR3 catalog I had already created and exported from my MacBook. Other than the drive not being bootable on my Intel Power Mac, are there any risks to managing my LR3 catalog from this drive? Or should I only keep my LR3 catalog on a GUID partitioned drive?
This HD is not of course my startup drive, but only to be used to store my photos.

Oops, I should have used "Mac Pro" to describe my Intel machine, not "Power Mac"

Partitioned drive with "Apple Partition Map" but installer says that the disk is not bootable

and refuses to install 10.5 on it.
I have an external drive hooked up to an eMac. The plan is to install 10.5 on the drive, and then put the drive into a G4 powerbook.
I booted the eMac from the 10.5 retail install disk, partitioned the external drive into 1 partition, with the 'Apple Partition Map' option selected in the options. But when I go to try to install onto the disk, it has a red X and says that the computer can not boot off of the device so it refuses to install.
Can anybody tell me what step(s) I missed?

The choice I selected was "Mac OS extended (Journaled)" which I think is HFS+journaled -- or at least none of the other choices on the pull-down looked remotely correct.

GUID vs. Apple Partition Map

On my new Mac Pro the G-Raid3 will not mount in eSATA. It's fine in 800 Firewire. Out of the box it was set for Apple Partition Map and worked fine on my previous Intel Mac Pro on the same eSATA card.
Suddenly on the new MacPro it doesn't mount. G-Technology told me I have to repartition it as GUID. They said I have to select "Free Space" first and then proceed normally. (It's a 3-TB drive Raided internally.)
Now I checked a Time Machine backup disk I am using on my laptop. That also is Apple Partition. The laptop itself is GUID.
If we're going to keep up to date in an Intel world, is it wise to get all the drives into GUID format?
And what about Free Space? Should that be chosen every time? Why not just OS X Journaled?

Check on TimeMachine specs, I thought it req'd GPT(GUID).
GPT is a better 'modern' partition format and features.
I've never been much of a fan or in favor of multi-interface, handy for home users.
G-Tech's advice. The only way to change a drive to GPT from APM is
click on drive (not volume partition)
change from "current partition" to anything else, ie, "free space"
So that the OPTIONS.... will be available at the bottom.
Click OPTIONS
change to GUID and click APPLY
Change partitions to what you need. Mac OS Extended (journaling)
Click Apply.
Destroys any data.
Things that worked in older Mac Pro may need firmware or driver updates. So your controller might - and please include things like what controller you use.

GUID partition table/Apple Partition Map

Hello,
I just bought recently a Seagate FreeAgent Go for Mac and I'm planning on using it with Time Machine. My question is the following: since the Seagate is partitioned following the GUID partition table, and my mac's internal HD is partitioned according to the Apple Partition Map; would that affect in any way the backups?
Thx!

From http://developer.apple.com/documentation/Darwin/Reference/ManPages/man8/diskutil .8.html
the +APMFormat specifies that an Apple Partition Map scheme should be used. This is the traditional Apple partitioning scheme used to start up a PowerPC-based Macintosh computer, to use the disk as a non-startup disk with any Mac, or to create a multiplatform compatible startup disk+.

How to set up Apple Partition Map not to be a Master Boot Record

Hi.
In order to copy Leopard install disk to a flash drive I need format the 8 G Cruzer (on which the U3 was removed) to set up Apple Partition Map not to be a Master Boot Record to be bootable on my Quicksilver G4. I never used partitioning before, step by step please.
W.W.

Hi, motsteve -
Forget booting USB on any G4
USB booting is possible on all G4s and later models starting with the G4 (AGP) models, per -
Article #58430 - USB Info and Benefits of Dual-Channel USB
I think I read somewhere (couldn't find it just now) that the earlier versions of OSX are not USB bootable, so booting to USB on G4s might need to be by using OS 9.
I've never tried USB booting. However, I have made a bootable Zip100 disk for my G4/500 (AGP), using its internal Zip drive. Did it just to see if it would work - it does. There's a fair amount of room left over on the 100MB disk, too.
Intel-based machines are also USB bootable, per this article -

Disk Utility error "Mediakit reports partition map too small. 3TB

So I have a Mac Pro with a 3TB inside, but Snow Leopard won't recognize the whole 3TB. I can format it, but it only allows 801.23 GB. The remaining space is left as Free Space. When I try to resize the Volume, I get this:
I get this error: " Partition failed with an error." MediaKit reports partition (map) too small.
Can someone help me find a way to utilize the 3TB as it was intended to?

Anyways, i've made it work. My process was this:
Problem:
1. I put MacPro into Target Disk Mode to mount to my 2011 MacBook Pro. Disk Utility on MBP would only see 800GB.
Solution:
2. Booted the SL CD on the MacPro and ran Disk Utility from there. In the partitions tab, I chose 1 partition, and hit apply.
3. "could not unmount disk."
4. So I tried to partition it again, and it worked this time. 3TB Available.
5. I then booted the MacPro using an external HD with OSX on it to run CarbonCopyCloner to reimage my backup.
I hope this helps anyone else with the same problem.

How to low-level format entire drive, including partition map?

Hi everyone,
I have an OWC-supplied, 80 GB, ATA hard drive (OWC Neptune), which originally shipped in an external, FireWire 400 case. The drive stopped working; disassembly of the case led to the discovery of a burned trace on the Oxford bridge. While the bare drive itself has no manufacturer name, its label style and model number listed on the drive clearly show it to be a Maxtor 6Y080L0, 80 GB.
Having removed the drive and installed it into a test Power Mac G4, the physical drive is recognized by Disk Utility (albeit with no partitions, mounted or otherwise). The drive emits "normal" power and spin-up sounds, with no clicking or other sounds that might normally indicate a failed drive. However, Disk Utility is unable to actually partition the drive—when attempted, the "Creating Partition" progress bar advances to about 1/8 of the way across, then moves no further (even if many hours are allowed to pass). Console reveals nothing as to what is stopping the format.
Moving further, I attempted to blow away the partition map with pdisk, but encountered several read errors in the partition map itself. I even went so far as to attempt to "build" a partition map, one partition at a time, based on the settings I found on an identical drive that is functioning properly. Although this seemed semi-successful, attempting to write the partition table again resulted in a couple of errors.
pdisk: Unable to write block 8 (Input/output error)
pdisk: Unable to write block 9 (Input/output error)
pdisk: Unable to write block 10 (Input/output error)
pdisk: Unable to write block 11 (Input/output error)
While it's entirely possible that the blown component on the FireWire bridge might have also taken out the drive, I'm not a big believer in coincidence and my thought is that the trace blew during an access of the partition map, corrupting it to the point that only a low-level format of that portion of the drive can potentially salvage it. There is no data on the hard drive I am worried about losing, but I'm not one to easily say "die" and so I'd like to be able to restore this drive to functionality, if at all possible.
So after setting the table for you here, my questions are as follows:
1. Is there any way to low-level format an entire drive that does not have a readable partition map? In essence, effectively returning the drive to something resembling an out-of-box, unformatted state? CLI is fine, and I'm even open to trying to throw the thing in a PC box, install Yellow Dog Linux so as to have GUI access to pdisk, etc.
2. Does anyone have any other suggestions for me regarding this matter?
Thanks much for the time,
MBJ

Thanks to all for the suggestions. I'm about to give up on it, although I will try the PowerMax software recommended by Michael Black.
And The hatter: Don't let this burn you on Neptune drives—one of my client offices has been using about 20 of them for the past couple of years now, on a daily basis, for large-scale imaging projects, and the little drives have been real champs. We're even using them to dual-boot both Intel- and PPC-based systems, and they've just been outstanding. Methinks the component failure probably cascaded down to the drive, and while yes, it *****, such things happen in any batch of components and I'd buy another Neptune today if I had the need for yet another external.
As for Matt Broughton: S.M.A.R.T. shows no problems when the drive is connected directly to the ATA bus. But then again, I've only run into a few drives that S.M.A.R.T. has ever reliably reported on—it's still a black art, to be sure. The WikiPedia article on S.M.A.R.T. goes into more detail about its pervasive flakiness.
For now, the drive has begun to beep about once every 2 seconds at boot. This lasts for about 30 seconds, after which the drive continues to spin but no further beeping is heard. The drive no longer shows up in Disk Utility, even as an unmounted drive/volume. So, I'll probably try it in a PC w/PowerMax just to say that I did, but beyond that, it's probably ready for disassembly as an example drive.
80 GB—sniffle…
Thanks again to all for your suggestions!
Take care,
MBJ

Can't install on Apple Partition Map (PPC)

I have a powerbook G4, everytime I try to install, I get the error message:
+You cannot install Mac OS X on this volume. To enable installation on this volume open Disk Utility from the Utilities menu and repartition this disk as ‘GUID Partition Table’.+
But as I understand it, a ppc mac can't boot from GUID, so why is it asking me to do this?
on googling I came across this guide ( _http://northstarlabs.net/2007/11/04/leopard-firewire-target-mode-os-install/_ ) which sounds exactly like what I need, but I know little about using the terminal.
Am I doing something wrong?
Or Does anyone know any other ways to bypass the partition check?

There is part of your problem, when you put the macbook in target mode and then try to load from the mac mini, it uses the information from the mini to try the install. Here is what you need to do
Insert Leopard disk (Actual Leopard disk, not restore disk for mac mini) in the Mini, shut it down and then restart the Mini in target mode.
With the macbook off, and the Mini in target mode connect them together with Firewire cable. Start Macbook and immediately after chime press and hold alt/option key. This should bring up disk selection menu. Find the Leopard install disk, select it and click on the straight arrow. Leopard installation should start. Make sure when you get to the point of which harddrive to install to, Pick the macbooks harddrive (Since the mini is in target mode its harddisk will also show up in the list)
If you are unsuccessful with that method, there have been some known issues with the Leopard installation disk and you will need to contact Apple to get it replaced.

The Spindle and Apple at Start Up Question

Background: had to replace my hard drive. Transferred data from Time Machine. Had the internet plug in (to the USB Port) and the white plug (with green light on) in from the wall. Was not running on a battery. Finished, and shut down. Went to relaunched half hour later - just a gray screen, and about 30 seconds later, a pulsating image of the world. No spindle, no apple. Shut it down. Took out plugs. Relaunched without any attachments. Spindle and Apple as usual. Tried it again with plugs in. No spindle or Apple. Went into Systems Pref. Went to Start Up. The hard drive WAS NOT highlighted. I highlighted it. Question: is THAT the reason why there WAS NO spindle or Apple with the plugs in? I have not shut it down, as I need to work with my computer for the next several hours. If I've corrected the launch by highlighting the desktop hard drive in System Pref. will I see the spindle and Apple, with plugs in when I shut it down tonight, and Relaunch tomorrow?
Thank you for any response.

That should work. Here's a link that describes the flashing world a little:

Evidently your Mac was looking for a network to boot from instead of booting from your hard drive.
Good luck!

Visual Studio 2005/2008 and Crystal Reports versions/upgrade questions.

I've tried posting this question on the MSDN forums and gotten no response.
I've downloaded and installed VS 2008 Beta 2.   The versions on the Crystal Reports files included are 10.5.0.1806
I'm currently using VS 2005, with the included Crystal Reports. The versions on those files are 10.2.0.xxxx. I've created an desktop app (in VB) which stores it's data in a database and uses the CR 10 runtime merge modules to generate a report.
I was considering upgrading the Crystal Reports version to XI. I would like to allow customers to modify my delivered report with their own licensed copy of CR XI. I am not providing any functionality within my app to create or modify the delivered .rpt or use it outside my application.
Questions:
Do I need to update the runtime files to CR XI to support rpt files modified with CR XI? Current runtime files are being delivered with the CR 10 merge module.
I see a Crystal Reports for Visual Studio upgrade to CR XI.
Can I update the merge modules to CR XI and still use the CR for VS2005 for development?
Does it make any sense to update CR for VS 2005? Or to get the full CR XI Developer edition? My usage of CR functionality is very limited.
Would there be any benefit to waiting for the release of VS 2008?   How does that change the scenario?
How does Crystal Reports for Visual Studio fit in with the Crystal Reports Lifecycle? It's not mentioned on Business Objects End of Life Dates page . Crystal 10 has a Patch EOL of 31-Dec-07.   Does this apply to CR for VS 2005? Where does 10.5 fit in?
My main concern is allowing customers with CR XI to change the format of my delivered .rpt to run with my app. Adding their company name, logo, etc.   My testing show a CR XI report still works with my current app. But, going forward, what should I deliver and what do I need to use to continue development?

To use Reports designed in XI, you need to use XI or higher runtime, running them in older versions may work, but you may encounter unforeseen issues doing so.
If you are to use VS2005 for development you need to use XI Release 2 (11.5) runtime.
If you are going to use VS2008 for development you need to use Crystal Reports 2008 with Service Pack 0.
The support end of life for versions of Crystal Reports bundled with Visual Studio are linked to what Microsoft's lifecycle for the product is. Generally if there is a workaround for the issue that is simple enough, there will not be a patch created.
The changes you are expecting the customer to do can be accomplished with our RAS SDK which is available without using enterprise starting with Crystal Reports XIR2 SP2.

IPhone 6 and apple pay pre-sale question

When will Apple Pay be rolled out to the UK?
Will I be able to get rid of all my Loyalty cards and store them on Apple Pay?
I have absolutely loads of cards and they drive me mad.
Will I be able to put my Boots Advantage Card onto it and collect and spend points with an iPhone 6 at checkout in store? Will I be able to do likewise with the Nectar card, Morrisons Card, Shell Card, plus any other loyalty and discount cards as well as my debit and credit card?
On an iPhone can you only store MP3's or can you store and play other formats like wav and ogg vorbis?
Do you have to buy all your music through iTunes or can you add your own music including mix CDs etc? I have noticed in the past not all mixed music transitions flawlessly from one track to the next in MP3 format. One of the many faults with this lossy music format.
Thanks for help answering any of these questions. I have an aging android at the moment. May consider switching to Apple.
