Should I format U disk at first or recover data at first?

first or recover data at first? I used Power Data Recovery
Format would damage metadata (file system information) so the only way to recover data would to be scan the whole disk and find binary files with signatures (headers) to get size of them. Doable if disk is not fragmented. There are tools capable of doing
what you want, see:
RecoverMyFiles
http://www.recovermyfiles.com/
(I'm not affilated with these guys)
So making long story short: try to get your data back BEFORE you'll wipe out file system information with a format.
Hope this helped :)

Formating second partition as GUID without deleting data on first?

hi!
I'm trying to "restore" the .dmg image of leopard on my external USB-drive. I managed to generate a second partition on my external drive (10GB) but could not format it to GUID (so that I can start up from it).
Question:
Is it really not possible to simply format the second partition as GUID while leaving the first partition completely untouched? The only option I could find deletes ALL data from the external disk which is clearly not what I intend to do.
Have I missed something? Are there alternatives to using the disk utility?
Thanks a lot!

AFAIK, the GUID or GPS applies to a complete disk not a partition.
Partitions are things like NTFS, HFS+ and so on. These can be different on disk, but I am quite sure that the APS or GPS applies to the low level structure of the drive and perhaps the boot area and applies to the entire drive.

Hard Disk Won't Boot - Recovering Data w/ Live CD

Hey guys,
I have a MacBook.
My operating system got corrupted. I can't boot into it. I also have a tiny Linux partition installed, which can boot totally fine (therefore, not a hardware problem).
I booted into a Linux Ubuntu 7.10 Live CD, and was able to see my hard disk partitions as accessible. I could navigate to the Ubuntu partition, and see the data there.
HERE'S THE THING:
I can also access my OS X partition, and see the data. The problem is that some of the folders I can open just fine, while others have a tiny red circle in the top-right of the icon. When I try to open those ones, it says that I don't have permission.
Is there a way around this?
I am trying to rescue my data before wiping the hard drive.
I have already tried repairing permissions with the original install disk, and it won't work. I have tried booting in FireWire target-disk-mode, and it won't work. I have tried using DiskWarrior, and it worked only enough to tell me it won't work.
The Apple support guy said to try this Linux Live CD. Any ideas?
Thanks in advance!

Hey dude,
Thanks again for the followup help.
I have done a million diagnostics, here is a short list:
Tried booting resetting PRAM - nothing.
Tried booting in Verbose mode, nothing
Single-user mode, nothing
Safe mode, nothing
Nothing will boot.
I have Ubuntu installed on a different partition which boots totally fine, so it's definitely not a hardware failure. Apple said this as well.
I boot into the install DVD, and run the Disk Utility FIrst Aid. It can't repair the disk, and gives me errors.
The hard drive is nearly full, so there's not 15GB free to do a Archive and Reinstall the OS.
Apple said that the OS is corrupt, and I have to recover the data and wipe and reinstall.
I tried booting in target disk mode, and the host computer can't find the target mac (I tested it with 3 different macs and the cable works and everything else works fine). Apple said this is probably due to the "headers and footers" of the partition being hard to read.
I tried DiskWarrior, and at first it DID find the disk and data, and it said IT COULD RECOVER IT. I did a hardware test and it was fine. I did the permission repair, and then it found all my data and allowed me to browse it before recovering it, but it also gave me errors. Then it said that it COULD NOT recover it. When I tried to run the recover, it said first to reboot. After rebooting, it said that it couldn't even find the Mac hard disk at all, let alone repair it.
Then after trying to boot again as normal, instead of simply staying at the permanent "boot up" screen, it goes to a gray screen with a black message that says "Please reboot your computer".
I am able to boot from an Ubuntu Live CD, and I can even see my Mac disk as accesible. I mount it and can browse SOME of the data, but other folders it says I don't have permission to access. Unfortunately, it's the locked ones that I need the data from.
I didn't put any extra locks on these folders in OS X than the other folders that I can access, so it's nothing like that.
Any ideas?

Problem in formatting ,scan disk i need to set cd rom as first boot device

hi,
For formatting ,scan disk i need to set cd rom as first boot device
But whenever i do it from manager and restart the machine It takes long to get back the console of the machine.
By the time machine boot's up, its from hard disk.
How would i avoid such situation?
Please advice....

hi
could you describe more precisely where are you?
do you mean BIOS boot settings? if yes, you choose CDROM as first, boot and your systems start from CD disk.
what operating system do you use?
what console do you mean?

How should I format and partition my two new hard drives in a 2010 MBP?

My good old mid-2010 13" MBP just lost its stock hard drive. I've decided to keep the laptop, set aside the defunct drive for future data recovery and pop two new drives in the computer along with a 8GB ram upgrade (two 4g ddr3 chips).
The two drives I'm working with now are a 256GB Crucial MX100 SSD (intended for my OS and startup) and an HGST 1TB Travelstar (for apps and storage) that I'm popping into the optical bay [via conversion tray].
I'm putting everything together myself then taking the build to tekserve (or the apple store? which should I go to for OS re-install and formatting help? ) to re-install my original OS (snow leopard) or mountain lion. i cant find my recovery disks and also can't download mountain lion on another comp. to boot my laptop build with.
Is it okay to just throw the drives in myself and let pros format them for me? I know i should be installing the OS myself but all of my workaround options are fleeting due to time constraints... gotta get my OG setup up and running.
Thanks everyone.

sageakash,
I have the same model MacBook Pro as you. If the 1 TB Travelstar HDD is a SATA III disk, then you might have trouble with it in the optical bay due to the connecting cable. To minimize problems, put a SATA II disk rather than a SATA III disk into the optical bay.
If you want your MacBook Pro’s original iLife apps to be installed on your new disks, then you’ll need to have Snow Leopard installed first, even if your target OS is Mountain Lion; they can’t be subsequently installed from the grey Applications Install DVD once a newer version of OS X is on your boot volume.
What is your concern with pros formatting your disks? What’s “OG”?

Format Startup Disk without Installion CD

Hey guys,
I'm currently out of town and don't have access to my Mac OS X installation disc and of course I've run into a bit of rough road recently which has lead to me needing to format my startup disk, zeroing out all data.
I partitioned my 500G Western Digital and made a fully bootable backup of my disk using SuperDuper!. I booted from the drive and it works completely fine "I'm using it now". I proceeded to open disk utility needing to format the internal disk with the zeroing out data security option. I set the format to Mac OS X (Journaled), gave it the same name as before, and clicked erase. It prompted me with an error stating "Cannot erase because the drive could not be unmounted". So I attempted to unmount the drive and it prompted me with another error stating "Could not unmount the drive because it is in use... please close all applications...etc., which didn't work".
After doing a bit of research I've read that to erase your hard drive you need to use your installation disc and follow the instructions, etc, etc.
Now, as previously stated I don't have access to my Leopard disc so that's not an option, at least for another 3 weeks, when I return home.
So my question is: Is it possible to format/erase your startup disk "My internal drive" without the use of your OS installation disc, and if so how would one go about doing it?
Thanks in advance.
Kind Regards,
Rich

Yes, that should work. It seems like some files are in use on your internal drive. I suggest you drag the icon for your internal drive into the trash to unmount it before you run Disk Utility to erase it. If you can't unmount it that way, try rebooting first. If that doesn't do it, try booting up in [safe mode|http://support.apple.com/kb/HT1455] by booting up while you hold down the shift key.

Format my disk- MacBook Pro

Hi! I upgrade my software to Lion so I don't have the CDs to format my disk..
What I should do? Should I use my snow leopard and then upgrade? or what I have to do?
I want to format all my macbook pro for the first time in 3 years. Is a :
MACBOOK PRO
15-inch, Mid 2010
Processor 2.66 GHz Intel Core i7
Memory 4 GB 1067 MHz DDR3
Software Mac OS X Lion 10.7.5

Why? There's no reason to reformat the HD. If you do it, you'll lose everything that's on it. The way to do with Lion is to boot into recovery mode (restart holding down the CMD+R keys), launch Disk Utility, and have at it.

Format Recovery Disks?

Just bought my first Toshiba computer - a Satellite A500-01W, Part # PSAR9C-01W002, and after selecting to install 64-bit Windows 7 OS, I was going to make up the recovery disks for the computer using Sony DVD-R 4.7 MB disks that I just purchased as well using the Toshiba Recovery Disk Creator software program when it occurred to me that I don't really know whether I must first format these disks in order to do this or whether the recovery disk software program does this? Additionally, if I must first format the disks, then in what format should this be, i.e. Fat32, NTSC? and what mode, i.e. Music, Video, Text? which I presume is done using the OS software and not the Toshiba software. Oh, and one other consideration - the Norton anti-virus 30-day trial program is on this computer and while not activated, I'm wondering if it might still be running something in the background that might interfere with recovery disk creation? Any info and comments appreciated.
RVS (Randy)
PS: It's amazing how a simple consideration like this doesn't appear anywhere from the Toshiba help manual, this forum (at least the 200 or so posts I read before tiring) and the internet itself (looked for 2 hours or so)

It isn't about knowing Toshiba computers specifically or Windows 7. It's about having some common sense and a modicom of general computer knowledge. People who have never owned a computer before have been able to figure out how to make the recovery disks based solely on the content in the user's guide. It isn't rocket scence and is explained extremely well in the useer's guide. If they were to put every eventuality that could possibley happen in the user's guide it would be so large you wouldn't be able to put it on the hard drive and it would literally takes months to read it. It's been my experience that anyone who has to be walked through something like this in such detail quite often don't have enough general computer knowledge or general reasoning skills to be able to do things like this. Autorun has been around since Windows 95 which was released 15 years ago. It's inconscevable that anyone who uses computers on a regular basis wouldn't understand how it works and what to do when it pops up a windows dialog box. Only someone who hasn't used a computer at all or has been using an old computer with Windows 3 or Dos wouldn't know about it.
As for taking it to a store to have them made, that wasn't what I stated. I said take it to "someone who is more technically savvy to have it done for you". It's fairly easy to find someone who will do it for your for little or nothing. I know a lot of teenagers are quite capable of doing it for you. Most people have a neighbor or relative that could easily do it.
If I offended you I appologize, but sometimes people need to accept their limitations instead of whining about being picked on or put down.
If you don't post your COMPLETE model number it's very difficult to assist you. Please try to post in complete sentences with punctuation, capitals, and correct spelling. Toshiba does NOT provide any direct support in these forums. All support is User to User in their spare time.

Dual Boot Windows 7 with preinstalled Windows 8 on GPT-formatted hard disk and UEFI BIOS.

In the BIOS for the storage dives Boot´ option I
selected the: only UEFI, I could also select the option ´first UEFI´ but it doesn´t
change the failure of installing Windows 7.<o:p></o:p>
Thanks, Sia

If I am reading your issue correctly. Windows 8 came pre-installed on a computer with a hard disk setup as a GPT with UEFI configured.
If this is the case then the outcome you are experiencing is correct.
Windows 7 does not inherently have the ability to install into a GPT disk from the base installation.
The Windows 7 DVD is designed to install using BIOS mode.
Also note that Windows 7 x86 does not support UEFI mode.

2) How to SMI Label/Format a disk while OS Installation in Solaris 11.1?
As we know that ZFS is the default filesystem in Solaris 11.
We have seen in the Oracle documentation that for rpool below are recommended:
- A disk that is intended for a ZFS root pool must be created with an SMI label, not an EFI label.
- Create root pools with slices by using the s* identifier.
- ZFS applies an EFI label when you create a storage pool with whole disks.
- In general, you should create a disk slice with the bulk of disk space in slice 0.
I have seen the solution that using format -e, we change the labelling but all the data will be lost, whats the way to apply a SMI Label/Format on a rpool disks while OS Installation itself.
Please provide me the steps to SMI Label a disk while installaing Solaris 11.1 OS.

Oracle recommends below things on rpool: (thats reason wanted to apply SMI Label)

Cannot Format Hard Disks for Re-installation

Hello, first post,
I have a computer that stopped working and showed the folder icon with a question mark when attempting to boot the machine. Since I was able to boot to internet recovery and things appeared normal aside from not being able to find the OS. I attempted to verify/repair the disk using Disk Utility. My disk was unable to format after multiple attempts. I took the HDD out of the machine and put it in a known working machine and was able to format it. After putting it back in the original machine, I found that it only detected 67GB of the 500GB HDD when the working machine detected all 500GB.
I bought a replacement HDD and I am not able to finish erasing/formatting the disk. On both disks, it never gets stuck in the middle of formatting in the same place. Sometimes it gets stuck unmounting the disk, sometimes while creating the new partition. I am using the GUID partition map. Any ideas about what could cause these issues? Could I have a different hardware problem that might be causing this issue? Any help would be greatly appreciated.

If you live near an Apple Store, make a Genius Bar appointment to have the computer tested. Supposedly there is no charge for testing.

Should I format an OS8 drive with journaling?

Hello,
I have two separate hard drives on my G3; one 250 GIG drive with OS10.4.6 Tiger and another smaller 12 GIG drive that I plan to install OS 8.6 onto. (The 250 GIG drive for Tiger is formatted with journaling.)
Now, I am about to format the 12 GIG drive for OS 8.6 and I am using OSX's Disk Utility to format this 12 GIG drive.
I will format the drive as HFS+. Does it matter whether or not I format this drive (the one for OS8) with journaling on or off?
I know that OS 8.6 will not use the journaling feature but I might decide later that I could store a few of my documents (created from OS X Tiger) on this drive when booted into Tiger from my Tiger startup drive. In this case, maybe it might be a good idea to have journaling on for this little 12 GIG drive. I am not sure.
Should I format it with journaling or not? If I do, am I risking some discompatibility issues with running OS8 on a journaled drive?
Or should I just play it safe and format the little 12 GIG drive with no journaling?
Thank you.

Thanks Jim,
I agree with you 100%. However I have another G3 (a beige G3) and it needs a good OS and so I will give my OS9 to this beige G3 - I only have one OS9 CD. And so I am going to reserve my OS9 operating system for my beige G3. OS 9 is an excellent OS - I agree. This beige G3 will make a nice workstation for someone in my family for word processing and internet surfing and maybe for some of my old OS9 video games.
Then on my main computer, a more powerful blue and white G3 (350 MHz), I am running Tiger 10.4.6 on the main 250 GIG drive. Its very nice and functions as my main OS. Then I have a little 12 GIG drive on this same blue and white G3 on which I am going to install OS 8.6 for my older apps.
All my old classic apps should run fine on 8.6. I don't need them very often but its nice to have them when I need them for old times sake.
In a few months I will probably be buying Adobe Creative Suite for my Tiger OS on my main computer (the blue and white). Then I will have no need to use my old classic apps - unless I find a file that needs to be opened in an old original classic application - but I doubt that will be necessary very often - but at least I will have that OS8.6 ready just in case.
Thanks again Jim.

My mac can't find the volume" Data" on Time Capsule. Also Ican't find with the disk utility program the hard disk in the Time Capule; so I can't format the disk again. What can I do?

My Mac can't find the volume " Data" on Time Capsule, Also I can't find with the disk-utility program the hard disk in the Time Capusule.
So I can't format the disk in the Time Capsule
Deconnevt and then connecting the power tp the Time Capsule gives also no solution.
What can I do?
Joe

I listed the commands.. that is how you manually mount the disk.. follow exactly the commands I gave you.
In finder use top menu, go, connect to server.
Type in the following.
AFP://TCname or AFP://TCIpaddress (obviously you replace with the actual name or the actual IP address).
If that fails..
try
SMB://TCname
Here is the screenshot.
tardis4 being the name of my TC.
It should then ask you for your credentials.
And it should remember them in the keychain and be able to then get TM to connect.

Should I format the Time Machine HD before using it on new i7?

I have been using the external HD on my G5. Now that I am moving to the new iMac 27", should I format the HD and start with a clean drive for the new Mac?
If so, does it make any difference if the HD is formatted on the Mac or a PC?
Thanks

Your choice -- that's optional, not necessary. If you don't, when you do your first backup, you'll get a prompt allowing you to either start new backups or continue using the old ones. See #B5 in the Time Machine - Troubleshooting *User Tip,* also at the top of the +Time Machine+ forum.
If so, does it make any difference if the HD is formatted on the Mac or a PC?
Yes. Do it on a Mac. See #5 in the FAQ Tip for details.
