Gpt protective partition

Background...
    The laptop died in the middle of writing an email. Power will not switch on from battery or from power suply. Removing the HDD and replacing it with another (or leaving it out) does nothing, it never gets to the POST. Conclusion by HP. Laptop motherboard is dead and need to send it in. OK, now to the issue I need to solve.
When I remove the hard drive and connect it to another laptop as an external drive (using a USB to SATA adapter) the drive shows up, but it shows as a "Healthy (GPT Protective Partition)" with no drive letter associated with it, so I cannot copy files to another PC. When I try to talk to HP about the problem, they say that they do not help with backups. WHen I try to tell them I don't need help with the backup, but with what I need to do so \i can see the data, they keep saying they do not help with backups.
    Does anyone know how I can correct the partition information whthout loosing all of the data on the drive?
    I also keep getting told that the drive is formatted for use on one computer and you cannot read the data from another computer. What?? I have never heard that before. Is there any truth to this info or are they just reading stuff from a script and are just confused?
Thanks for any help you may have.

[Solved] Can't see GPT disk partitions in Windows 7 (64-bit)

I just added 2 new disks and had them set up equally with GPT and equal partitions, to use the partitions as RAID1 in Arch, and the rest of the storage for Windows. It works as expected in Linux (I guess), but Windows shows them as uninitialized.
Can this be due to the fact that I created the GPT and partitions using fdisk? Caus' gdisk can't see any partitions either when I start it. If so, is there any way to convert it or do I need to redo everything?
The output of "fdisk -l" shows this:

Corrupted Storage Spaces Protective Partition

I am running Windows 8.1 pro build 9600
In addition to the boot and data drive, I had two internal 2TB drives set up to use all their available space as a mirrored Storage Space Protective Partition, which, before the problem below occurred, contained about 1600GB of -- you guessed it -- largely
un-backed-up data.
I thought that if one drive fails, the mirror will act as backup, while stupidly forgetting the possibility of file corruption or ransomeware.
So, while the computer was in 'sleep' mode overnight, there was a power cut, and when I tried to reboot, Windows automatic repair kicked in and said it could not fix the system. I managed to boot to command prompt, and diskpart reported both offending
1863GB GPT disks online, with no free space
MOUNTVOL reported that the offending volumes had *** NO MOUNT POINTS ***.
CHKDSK appears unable to work on an unmounted partition.
I could try EaseUS pro data recovery, but from previous experience this will take anything up to 3 or 4 full days, and will not repair the damaged mirror. However, I'm not sufficiently familiar with DISKPART to know if, for example, the RECOVER
option might be helpful, or if it might further mess up the file system, in which case a commercial data recovery like EaseUS may have more difficulty in sorting out the mess.
I'd be most grateful for some ideas about what to do next...

Thank you for your reply. Since my fist post, I have managed to start the PC from a duplicate boot partition set that I made after upgrading to 8.1.
Disk manager shows the disks as present, healthy, and marked as Storage pool.
However, all options are greyed out so I cannot assign a drive letter, and as before, MOUNTVOL reports
*** NO MOUNT POINTS ***.
The problem with the recovery apps I've tried so far is that after scanning either drive, they find the partition, but classify it as UNKNOWN. If I run the same apps on other disks they can recognise all the usual FAT, FAT32, NTFS, ext2, ext3, ext4 etc.,
but they don't seem to know about Storage Spaces Protective Partitions.
Do you know of some recovery app that understands this type of partition?
I know I can try getting the recovery app to read it as a RAW partition, but the problem there is that from previous experience I guess it will take 20 hours or so to run, and then not be able to build a useful directory tree.
There are probably 200,000 or so files on the partition, of which I only need to recover one folder in which there are about 400 files not otherwise backed up.

Can I use gpt to recreate/unerase a partition table? (Rebuild the GPT/GUID partition table?) I don't want to do FILE recovery.

(Yes, I've googled a bunch and read threads like this one already.)
Can I use gpt or some other app to recreate/unerase a partition table? That is, how can I rebuild a disk's GPT/GUID partition table?) I don't want to do FILE recovery.
What happened: Instead of erasing a single partition off a disk with many partitions, the entire partition table was erased (using Disk Utility, w/o deleting the underlying files). Somehow the "Erasing a disk deletes all data on all its partitions." warning message was missed.
I have a copy of the output of df, with the number of blocks in each partition, from just prior to the erasure, so I should be able to recreate the GPT/GUID partition table. Editing the GPT with a hex editor is not feasible. Simply recreating the partitions with Disk Utility will overwrite the key filesystem tables on each partition, and I don't want to do that, plus Disk Utility doesn't allow me to specify exact partition sizes anyway.
Surely there's an app for rebuilding the partition table (other than emacs' hexl-mode!) for recreating/unerasing a partition table when the partition sizes and orders are known? I've looked at the advertising for a bunch of recovery software and none of them clearly indicate that they will do what I want.
I guess I can try using gpt on a copy of the reformatted drive I've made with dd, and see what happens. But perhaps someone knows of a tool that should do what I need, or knows if gpt is that tool or not.
There are answers and tools that will do FILE recovery - search for files and recover the ones that aren't fragmented or deleted. As far as I can find, they just look for files on the disk, and don't pay much, if any attention to the filesystem info or directory heirarchy, which in this case is valuable. Of course I could send it in to DriveSavers, or the like. But none of that seems necessary, and the scavenging file recovery apps won't do the job well,
E.g. some are mentioned here:
I don't want to do FILE recovery.
Thanks for any help.
The links in this post are to pages describing the underlined term, e.g. the man pages for df and gpt.
dd output includes:

Aperture has the ability to work with files in their existing location. They are called "referenced masters." When you import images, you should select the "In their current location" in the "Store Files:" drop down box. Have a read of the documentation for full specifics. Unsure how you can resolve your duplication; might be some work but next time have a read of the manual first
Information for versions is stored in the Aperture database (library file). The masters can be inside the library file itself, or they can be somewhere else.

Can't use my old HDD after upgrading with new one,old is GPT protected

Hi everyone! First of all I would like to thank you in advance!
Recently I upgraded my old HDD on my MacBookPro. I made a clone of the old disk, installed the new one in the MBP and putted the old one in external enclosure. Now I'm trying to use the old disk with the enclosure, but it doesn't appear in Finder, it appears in Disk Tools, but I can not perform any actions on it. I tried to erase it, but with no success! The old disk is GPT protected and I don't know what to do. Tried to erase it with Windows and Linux with no success neither. I know the enclosure works because it recognize every other disk, but my old one is untouchable to my Mac OS! I'm looking for possible ideas on how to make my old HDD usable with the enclosure?

Can't really help with your Internet issues, but I can put you on the path to leaning more about Macs.
If you're a former Windows user, there many resources on Apple's web site to get yourself familiar with how Macs and OS X work.
Here ard a few areas to spend time with

For the video tutorials, in the video search box, just type in OS X. You'll get a list of OS X video tutorials to watch as you learn to use your iMac.
Start with the Anatomy of a Mac video first, Then the Finder Basics video second. After you have watched and put to use these two videos, you can watch any other OS X video you want in any order.
Here is a free eBook download of David Pogue's OS X Snow Leopard The Missing Manual here. While OS X 10.7 LIon and OS X 10.8 Mountain Lion work a bit differently than OS X 10.6 Snow Leopard, there are many things that still apply.

[SOLVED] How do I increase the size of an existing GPT ext4 partition?

I found some advice here
http://ubuntuforums.org/showthread.php?t=1389429
but I'm not sure whether the information is correct
1 Run parted on your device: parted /dev/sdX
2 Change display unit to sectors: unit s
3 Print current partition table and note the start sector for your partition: p
4 Delete your partition (won't delete the data or filesystem): rm <number>
5 Recreate the partition with the starting sector from above: mkpart primary <start> <end>
6 Exit parted: quit
7 Check the filesystem: sudo e2fsck -f /dev/sdXX
8 Resize filesystem: sudo resize2fs /dev/sdXX
I'd like to increase partition #2 from 200 Gig to 300 Gig using gnu parted.

From the wiki gparted topic:
GParted is a GTK+ frontend to GNU Parted and the official GNOME Partition Editor application.
I think gparted can do anything gnu parted can do. The warning about ext4 in the topic you linked is from 2009, and recommends using gparted with a version higher than 0.6.2-2. Gparted 0.14.0-1 is currently in the Arch repo, so I think it's probably safe.

I'm a little confused about gpt and partitioning

Note: following the youtube guide provided in the link
I'm trying to make a VM in VMware and when I run cfdisk I get option like sun, dos, gpt, and a 4th item. Now I've been able to successfully install Arch with dos before by disabling efi. But I am trying to get this up and running because I believe I have efi on my desktop motherboard and plan to install arch as dual boot setup with windows 7. So when I do cfdisk and follow it further, I don't know a) what type to make a drive, I know one has to be swap and I assume the other has to be "Linux Filesystem", and b) how to set a bootflag on a particular partition.
P.S. Was also reading on the arch wiki (link also provided) and I don't think I'm reading this correctly it's saying that if Windows is instaled on EFI then I cannot install Arch as GPT either? What if it's on seperate hard drives?

There's an "ef00" type (if you're going to use EFI) and an "ef02" type (if you're going to use MBR). These you should use instead of boot flags. If opting for EFI the esp needs to be FAT32 (the ef00 type) and is recommended to be mounted at /boot mountpoint. If opting for GPT+MBR grub will need a BIOS boot partition (ef02 type) which is ~2MiB. I assumed you want GPT (required for EFI).
Now regarding dual booting. Windows doesn't support GPT+MBR. So either go with GPT+EFI or MBR+BIOS.
Thank you, just to be sure the (I'm pretty sure I'm right, I'll make the /dev/sda2 (non-Swap partition) the EFI type since I want to recreate scenario of dual booting assuming I have EFI. I'll try it set to MBR later. Now to a question, On my last VM I believe I had it set to Linux Filesystem, it still works as far as booting goes. But I wonder why? I hadn't set bootflags, neither had I set it to EFI/MBR.

How do I mount a password protected partition?

2.5 GHz Intel Core i5 Mid-2012
Yosemite 10.10.1
Several weeks after installing Yosemite and suffering the frequent indignities of that wonderful update, now a partition disk on my laptop won't mount. It requests a password, and when I provide it and click ok nothing happens. The disk image doesn't mount on the desktop.
Interestingly, after typing in the password and clicking ok and not having it mount on the desktop, when I run disk utility it recognizes the partition and indicates it's already mounted. When I tell disk utility to unmount it I get the message "Unmount failed. The disk “Disk Image” could not be unmounted. Make sure that all applications and files are closed on this disk."
If I restart the computer and run disk utility, it indicates the disk is unmounted. I am appreciative of any support you can lend. I'm not a geek and I'm only vaguely aware of terminal, so have mercy in your responses, please

If it's a Numbers file, you will be prompted for the password when you attempt to open the document.
If it's an Excel file, you must arrange for it to be unlocked in Excel and resaved without locking before opening in Numbers.

MDT 2013 + create 5 recommended UEFI/GPT drive partitions

Hi
My end goal is to deploy a custom x86 image to a UEFI device (tablet) using a USB stick. It is likely that my .wim file will be >4GB, but for now, I'm just trying to get the process working with a standard OEM <4GB .wim file.
As per this post, I have performed steps under sections 5.1, 5.2 and 5.3 MANUALLY, by booting the tablet using a WINPE 5.0 USB and running
1) diskpart /s E:\CreatePartitions.txt
and
2) E:\ApplyImage E:\Images\ThinImage.wim
Q: Above worked perfectly and it's exactly what I'm looking for. How do I incorporate 1) + 2) into MDT, or do I simply attempt to replicate the code from 1) + 2) under "Format and Partition Disk" under PreInstall\New
Computer only step?
Any advice or pointers would be really appreciated.
Many thanks in advance.

Recovery images, that's a different story.
First option is to increase the size of the System partition to the desired size:
BdeDriveSize=5000
Otherwise, the best solution I've seen is to build the standard MDT partition configuration using the default MDT "Format and Partition" step. and *THEN* shrink the partition to the desired size. Yes Shrink.
The other option is to increase the size of partition 1 from
See Mike's post on WimBoot for the example script LTIApplyWim.wsf script that shows how shrinking works.

How to back up files from a MacBook to an XP PC

Hi
I am a non-professional but reasonably competent PC fixer for friends and family, within the MS Windows product set thus far.
A friend's son has dropped his MacBook and now has the '?' question mark on boot. He has taken it to an Apple Genius, who after a bit of failed feagling with recovery disks, has confirmed it is 99.9% likely to be the Hard Drive (particularly as there is occasionally clicking, likely from the actuator) and has been (a) quoted an astronomical figure to fix and (b) has asked me to have a look.
It's got a standard 2.5" SATA drive and I have a bit of kit to turn a drive removed from a PC / Lappie into an external USB drive, which I typically use first and foremost in my other 'bad HD' related repairs to retrieve any data not corrupted by bad disk sectors.
I've connected the SATA from the MacBook to an XP notebook and can see the drive in Control Panel / Computer Management / Disc Management as a 'Healthy (GPT Protective Partition)', but cannot view it via any Explorer based functions, i.e. I cannot get the data off of it.
New ground for me and Google not offering anything illuminating; I can't assign it a Drive Letter so what, if anything can I do via XP to retrieve and back up the data as an external drive, or do I need to plug it as an external USB into another Mac?
Many thanks in advance for any information / pointers anyone can provide.

Apple format is not readable by Windows (is by late Linux distros), unless you use an application like MacDrive. Even so, do not hasten to install it, because many Apple apps and formats get corrupt in Windows. Your friend has, in fact, 2 problems: 1. he has no backup of his data (very bad and frequent behavior) 2. his disk is dead (and now finds how bad is to not have a backup).
A good backup of mac data is done to another disk formatted as HFS+ (mac os extended journaled). If you still think backing up unto a Windows PC is the only solution, then you must first ARCHIVE (zip or dmg) data on a mac, transfer archive to a PC, after replacing disk and installing the new system, move data back and unarchive it.
As Allan Eckert already wrote, this is not something recommended, but I tried to expose why. Now, with a larger horizon, you may choose best method. Tell your friend that he/she must purchase two disks: one to replace the dead one, one to be used as an external backup disk in an enclosure. At least from now on, he/she can avoid such situations.
In fact, all PCs, macs or Windows PCs, should be now sold together with an external backup disk, having at least the capacity of the internal disk. This should become the current sell policy of ALL computer manufacturers.

You may need to use EasyBCD.
XP should be installed before Vista.
Which is likely way XP boots.

No longer have permissons to RAID drive

Hi. I was able to create a 1TB Raid and store all of my info. Now, however, I cannot access the drive. I can see the folders and files, but when I try to open them I get a "This operation could not be completed. Unexpected error occurred (error code -43)." Under sharing and permissons, I can only "read." There is no lock button to unlock and for me to change the permissons. I can also no longer add new files to the RAID drive.
Under the disc utitiliy it has it lised at RAID Set, online, but with a lock button under each slice.
Raid Set Name: StorageRAID
Volume Format Mac OS Extended (Journaled)
RAID Type: Mirrored RAID Set
Any help would be greatly appreciated.

By the way, I cannot view the RAID in my windows bootcamp either. I can see the drives under computer management, but they are listed as status "Healthy (GPT Protective Partition)."
They also say they have 100% free space, which should not be the case. OS X at least notices 200GB is used.

With Time Machine I have an external hard drive formatted with Mac

With Time Machine I have an external hard drive formatted with Mac. The record contained files windows. How to recover?
Serious mistake: to connect a Mac to an external drive with data (important!) Windows, the warning appears: "You want to use the disk for Time Machine?" Wrong button, so in 2-3 seconds, the disk is formatted. Now Mac "sees" the disc but empty, Windows does not see it under "My Computer" but in "Disk Management" is reported as "hard core", "healthy", "GPT protective partition" Is there a way to retrieve the files? Sorry for my English Thanks

I'm having a difficult time following, I understand English isn't your native language. You may have good luck with Google Translate.

Installed SSD in Mac Mini to split as bootcamp drive, why can't I format the original drive?

I just bought a Mac Mini. Before I even booted it up I installed a 256 GB SSD along side the stock 1 GB hard drive, and reinstalled Mac OS and Windows 8 on the new drive using bootcamp. Everything is working fine, but I'd like to reformat the stock drive as one big NTFS partition so I can use it as shared storage between the OSes.
When I view the drives in Apple's Disk Utility, it shows the following partitions:
256 GB SSD:
SSD - Mac OS Extended (Journaled) (A silly name for my new Mac OS partition)
Bootcamp - NTFS (A silly name for my Windows 8 partition)
1TB Apple HDD
Macintosh HD - Mac OS Extended (Journaled) (The original Mac OS install from the factory)
When I view the drives in Windows Disk Manager, it shows the following partitions:Disk 0 (1TB hard drive)
200 MB Healthy (EFI System Partition)
930 GB HFS Healthy (Primary Partition)
620 MB Healthy (Primary Partition)
Disk 1 (256 GB SSD)
200 MB Healthy (GPT Protective Partition)
(E:) 118 GB HFS Healthy (Primary Partition)
620 MB Healthy (Primary Partition)
BOOTCAMP (C:) 119 GB NTFS Healthy (System, Boot, Page File, Active, Crash Dump, Primary Parition)
When I try to erase the 1 TB drive in Apple's Disk Utility, it gives me an error saying "Disk Erase failed with the error: Couldn't unmount disk". Is my old drive still holding something important, like a master boot record or whatever the modern equivalent to that is? Should I use Windows to try to erase the 1 TB drive? I'm pretty confident I'm booting into the copy of Mac OS on the new SSD, because the bootcamp startup screen shows the OS partition on the old drive as well, and I'm selecting the new one. The EFI partition on the old drive seems suspicious to me, is bootcamp using this or something?

Bootcamp - NTFS (A silly name for my Windows 8 partition)
1TB Apple HDD
Macintosh HD - Mac OS Extended (Journaled) (The original Mac OS install from the factory)
When I view the drives in Windows Disk Manager, it shows the following partitions:Disk 0 (1TB hard drive)
200 MB Healthy (EFI System Partition)
930 GB HFS Healthy (Primary Partition)
620 MB Healthy (Primary Partition)
Disk 1 (256 GB SSD)
200 MB Healthy (GPT Protective Partition)
(E:) 118 GB HFS Healthy (Primary Partition)
620 MB Healthy (Primary Partition)
BOOTCAMP (C:) 119 GB NTFS Healthy (System, Boot, Page File, Active, Crash Dump, Primary Parition)
When I try to erase the 1 TB drive in Apple's Disk Utility, it gives me an error saying "Disk Erase failed with the error: Couldn't unmount disk". Is my old drive still holding something important, like a master boot record or whatever the modern equivalent to that is? Should I use Windows to try to erase the 1 TB drive? I'm pretty confident I'm booting into the copy of Mac OS on the new SSD, because the bootcamp startup screen shows the OS partition on the old drive as well, and I'm selecting the new one. The EFI partition on the old drive seems suspicious to me, is bootcamp using this or something?
