Regain memory after erasing hard disk

I notice that my new 1TB drive has lost its memory from 1TB to 930GB even after full erase operation in disk utiity even after selectiong 7 zero erase option. What happen to the 70 GB memory? Can I get back the lost 70GB? If yes, how do I go about it?

I see you're on 10.5.8; you may be seeing an apparent anomaly caused by differences in the way HD sizes are advertised and how they're reported by DU.
The manufacturer designates the drive using decimal notation, so 1TB = 1,000 GB
Your system reports using the (correct) binary notation in which 1TB = 1,024 GB
So a 1TB drive will be seen by DU as approx 977 GB (actually, it should really be 909 GB but that's another story)
The anomaly is addressed in SL by Apple changing DU to report in decimal rather than binary.

Disk Utility shows incorrect free disk space after erasing hard disk

Hello.
A few days ago, I tried to re-install my Mac OS and both Snow Leopard and Lion got the same problem. Before the re-installation, I erased the hard disk of my MacBook (late 2009) and the SSD of my MacBook Air (late 2010) - but after erasing the disks, the disk utility continued to show more or less 5 GB of used disk capacity, although the disks should have been cleared entirely I think.
After installing Snow Leopard or Lion, Finder showed as much free space as I usually expected it would, but Disk Utility still stated 5-10 GB less. For example:
MacBook: Finder shows 17 GB free, Disk Utility 6 GB free
MacBook Air: Finder shows 26 GB free, Disk Utility 19 GB free
There are 2 problems:
1) I need the original disk capacity. Think everybody agrees with that wish.
2) More important: The MacBook should still get a Bootcamp partition (unfortunately, that's necessary for my university's software.. :s): With 17 GB free space, it would work - but 6 GB doesn't.
I would be very pleased if somebody could help me. I searched the web many times so far but didn't find any real solution.

The available disk space reported in finder is totally wrong.
Even if it accounts for the local snapshots. In my macbook air it shows 120 Available in finder which is just 1GB less than my SSD capacity.

After Erasing Hard Disk, Can't Eject Startup CD

Not entirely sure where this belongs on this forum, but I am preparing to sell my old PowerBook G4 17in and so did a 7-pass erasure. In order to do this, I had to boot from a start-up CD for the MacBook Air that I have. It won't let me install this operating system, (fair enough,) but it also doesn't give me a way to eject the CD, because the PowerBook can't start-up or run without the CD. Any thoughts? Can I somehow boot it from my current computer and then get it to eject the CD?
Thanks.

Restart with the trackpad or eject buttons pressed, or press Option, Command, O, and F simultaneously, and issue the following:
eject cd
mac-boot

tornado2003,
What you need to do is boot into Safe Mode. Then delete the VGA Drivers.
After that boot normally and install the latest nVidia ForceWare Drivers
Take Care,
Richard
i guess you missed that:

What will happen to my key if my hard disk is formatted, will the key work after my hard disk is formatted ?

I want to know that, will my synchronized computer key will work if I format my hard disk because when hard disk is formatted then the key code will be erased , though I have saved my key will it work after formatting hard disk . let me know .
let me also know that what will happen if I lose the key I had saved then how will I access my synchronized computer .

Hi!
Can you point to the information where it says that the information is backed up in our servers? If that's mentioned anywhere we need to clarify it.
The only reference I found is here: [[What is Firefox Sync?]] and it specifically says that the information is synched across devices through our servers. If that's misleading, let me know so we can rephrase it.
Regarding storing the key in your pen-drive or any other back up system: This is the best solution and it will work smoothly after you format your computer. The key doesn't change when you format your computer so you will have no issues after all.

Not solved with Blinking Folder with Question Mark after Erasing Hard Drive

Thanks for the reply, held command+R again and it is trying to pick up WiFi, but it's not picking up my network and won't accept the password even when I try to put it in manually. Any thoughts on that?
Me too had tried the command+R and failed to manually connect to my network. Can anyone help?

Well, it was solved. I shifted to other place and tried other WIFis. One of the WiFi had the 2002f problem and another was fine, so the reinstall worked smoothly eventually.
On the apple support page it says that Supported network configurations and protocols includs both WPA/WPA2, not matter what they are, but it might not be true.

Is there any way that I can get back my iPhoto? After having hard disk replaced (no backup) and the operating system has been updated to Lion (no disc) I am wondering if iPhoto can be reinstalled with my Leopard discs?

As Niel pointed out, yes. The disk probably will look like the MBP disk (4) in this screenshot;

Reinstall erased hard disk.

I did a re-install on my girlfriends G4 iBook running X10.9 because of system problems, and now when the software disk ask for what destination to install on there is not option. I can't believe it had me erase hard disk and then doesn't give me option to partition another or create. Any suggestions?

Hi, dosotyidiot, and welcome to Apple Discussions. The "system problems" you were attempting to remedy by reinstalling may actually have been caused by a failing hard drive that is now completely dead.
Start the iBook up from Disc 1 of your latest OS X installer set. When the Installer appears, open Disc Utility from the Installer menu (if it's a Panther installer) or the Utilities menu (if it's a Tiger installer). If the hard drive doesn't appear in the left pane of DU, replace it. If it does appear, select the line that shows its manufacturer and model number, and click the First Aid tab in DU's right pane. Is the S.M.A.R.T. status of the drive shown at the bottom of the DU window? If it's "Failing", replace the drive. If it's "Verified," erase the drive using the Write Zeroes option (this will take several hours if it's a large drive). When that's complete, assuming it finishes sucessfully, quit Disk Utility to return to the Installer and proceed with the OS installation. If the zero write process can't be completed, replace the drive.

How do I recover tunes from my iPod after a hard disk crash?

I've just received my PowerMac back after a hard disk crash and am having to reinstall all software etc.
My iPod obviously contains all the music I'd downloaded from the iTunes music store and all the CD's I'd loaded manually into iTunes.
I can't see any way of copying the tunes on my iPod back into my iTunes library...
Can anyone help?
I had to use a data recovery tool to recover data from my disk after the crash and it's going to be a really long job to sort out what's what...

You can't sync or drag your music back from an iPod to iTunes, the transfer of music is designed by default to be one way from iTunes to iPod. However there are a number of third party utilities that you can use to retrieve the files from your iPod, this is just a selection. Have a look at the web pages and documentation for these, they are generally quite straightforward. I use Senuti but check the others out and choose whichever you prefer.

After erasing hard drive they wanted my apple ID to download Mavericks, but I am selling my Macbook

Hello
I am selling my Macbook Pro and so I decided to delete everything and clean the hard drive but when I clicked on "Reinstall OS..." It wanted me to log in to my apple store to install the OS Mavericks.
Luckily after it was installed it asked for my Apple ID and iCloud information again to which I skipped because I didn't want any personal information on the Macbook.
However, I did put my apple ID information when I had to install the Mavericks. So my question is would they somehow have access to my apple ID?

The operating system that was originally installed can be transferred to a new owner, but you cannot sell Mavericks or anything else you purchased with your Apple ID.
To prepare it for sale you must follow these instructions.
Refer to What to do before selling or giving away your Mac
If you enabled FileVault, disable it in System Preferences > Security & Privacy.
"Deauthorize" your iTunes account. Same for Audible if you have one.
System Preferences > iCloud > de-select "Back to My Mac" and "Find my Mac".
Sign out of iCloud. Select "Delete from Mac" when it appears.
Next: Remove all your personal information by completely erasing the Mac's internal storage.
If your Mac shipped with a grey System Install DVD, start your Mac with that disc inserted in the optical drive while holding the c key to boot from it instead of its internal volume, which should be erased before selling it.
If your Mac did not ship with discs, boot OS X Internet Recovery:
using three fingers press and hold the following keys: ⌘(command), option, and R.
With a fourth finger press the power button to turn on the Mac.
Keep the other three fingers where they are until you see the "spinning globe" icon.
This method forces the Mac to download its originally installed OS from Apple's servers, which will not require an Apple ID to install.
Remove any Open Firmware password if you created one: select Firmware Password Utility from the Utilities menu and remove it.
Select Disk Utility from the Utilities menu.
Remove any partitions you may have created.
Select the Mac's hard disk icon, then select the "Erase" tab.
Select the "Security Options" button and erase the disk.
The more "securely" you erase the disk, the longer it will take.
The fastest method is sufficient since all but the most expensive techniques and equipment will be able to recover securely erased data.
When it finishes, quit Disk Utility.
Select Install Mac OS X from the Utilities menu.
An Apple ID will not be required. If a prompt for an Apple ID appears, return to Step 5.
Do not create any user accounts.
When it finishes, shut down the computer.
If you want to install the bundled apps that were included with your Mac, restart by using your Applications DVD if one was included, and install the bundled apps. Apps bundled with newer Macs that shipped without discs cannot be transferred. Its new owner must purchase them from the Mac App Store using his or her own Apple ID.
If the Mac is being sold to someone outside the family consider the following additional information:
System Install DVDs that came with your Mac should remain with it forever, and must be included with the sale.
Consider including your AppleCare certificate if you bought it, printed documentation, even the box if you still have it. AppleCare stays with the equipment and is transferable.
Execute a bill of sale showing the Mac's serial number.
Once no longer in your possession, remove the Mac from your devices in My Support Profile.

Kernel panic after new hard disk

Because my macbook is very old (early 206 model) and has not many free space left I decided to put some more RAM in it and a new hard disk. First I installed the RAM and that worked fine, so I did a full copy of my old hard disk to my new one, using disk utility. However, after putting my new disk into my macbook I fired it up but it gave me a message that I should restart my computer. On the background I saw that it was about a kernel panic. I don't know what to do because I can't reinstall OS X because my SuperDrive doesn't work.
Does anyone knows the answer?
-Sander

First, are you saying you cannot boot the computer from your external clone? If so, then your clone is unusable so you will need to use the OS X installer DVD to install OS X on the new drive.
If you cloned your old system to the new drive and cannot boot, then you may not have prepped the new drive properly as follows. This assumes you have booted from the external clone:
Extended Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID (for Intel Macs) or APM (for PPC Macs) then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
Once formatting has complete you can restore your clone:
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Erase tab in the DU main window. Set the format type to Mac OS Extended (journaled, if available) and click on the Erase button. This step can be skipped if the destination has already been freshly erased.
4. Click on the Restore tab in the DU main window.
5. Select the destination volume from the left side list and drag it to the Destination entry field.
6. Select the source volume from the left side list and drag it to the Source entry field.
7. Double-check you got it right, then click on the Restore button.
Destination means the new internal drive.
Source means the external clone drive.

After erasing hard drive and re-installing Lion, is there anyway i can tell if all my files are gone?

Hey guys.
Basically i have sold my iMac after buying a new Macbook Pro. I erased hard drive in disc utility then reinstalled Lion from disc.
When i turn on the iMac now it does the usual welcome video, then proceeds to try and set up the machine. Which i dont want to do as i have sold it and he will want to do that himself.
Dont personally know the guy ive sold it too so basically i want to know how i can check to see if my files have actually been deleted?
Just so all my personal information isnt accessed by someone else.
Thanks a lot

If you erased the disk, the data is gone. If you want to be sure, you can open Disk Utiility again and erase the disk using a special method (select the hard disk > Erase > Security Options) before installing Mac OS X

How can I get my music back into iTunes after erasing my disk?

I had to reinstall Windows XP, erasing everything on the hard disk. I had saved the music files with backup software, so I now have them back. But iTunes won't add them to my library. I tried importing songs from a new CD to see where iTunes put those files, and then copying an album folder into the same location. But Windows wouldn't copy the files inside the foder. Nearly all the songs were originally taken from CDs in my collection, and the songs are still on my iPod Nano.

Wow,
Wonder why XP won't let you copy files?, perhaps you used a different user name?
Or these are the old DRM versions of the songs? You should be able to log into your iTunes account and authorize the computer and iTunes should recognize the songs.
Well since you have the iPod Nano, you can head over to iLounge and ask them what current third party software works to move your iPod Nano music back to iTunes.
Hope that works out for you

Getting "replace hard disk error (#10008)" even after replacing hard disk

Hi!
My laptop- HP Pavillion dv 6502- is 4 years old.
Recently, the hard disk supposedly crashed as I was not able to get anything other than a blank screen. I checked with BIOS diagnostics, and it showed error #10008- Replace Hard disk.
So, I went to an hp service centre and got the hard disk replaced.
My earlier hard drive was a Seagate 160 gb momentus 5400.3 disk.
New one is the Seagate 250 gb disk.
The laptop was working properly the day the hard disk was replaced. BIOS diagnostic status for the disk was "Passed"
But, the very next day when i tried starting the system, I got a blank screen again. I again went to BIOS and ran the diagnostic test. I performed the test twice. It took a lot of time to finish- jumping from Reaching till '80% complete', then jumping back to '10% complete', then '90% complete', then '10% complete', and so on.. finally showing '100% complete' and status : #10008 - Replace hard disk - both the times.
Then, I had to go out of station and so, I didn't touch my laptop for 2 days. When i came back, the computer was working fine and the BIOS test status said "Passed" for the disk
What could be the problem due to which my problem wasn't starting earlier- even after replacement of disk? Is it possible that the disk was not the problem in the first place?

Hi!
Turned out the second new Hard disk was also not fine. I went back to the service centre and got the hard disk replaced again. This time the laptop has been working fine.

System seems slower after new hard disk installation.

Dear all:
After a recent hard disk crash that caused me to lose a lot of important professional and personal information I replaced my old defective hard disk (a Seagate Barracuda 1.0 TB internal SATA drive) with a new one (a Seagate Barracuda 1.5 TB internal SATA drive).
The issue I am now experiencing may or may not be related to the new drive but I wanted to post it here and have your opinions about it. It seems to me that since this new hard disk was installed that my system is slower than it was before. Something else I noticed is that iTunes seems to hang every once in a little while, freezing and a while later resuming its operation (as if it were frozen while trying to read the information from its library located on the new hard disk ???).
Since the capacity of the new disk has increased some 50% compared to the older one, could this be the issue ? Can the fact that the 1.5 TB hard disk are new technology be a reason why this is happening (some issues still not completely resolved) or could it be that the capacity being so much greater requires the drive to work harder at finding the data ?
In case the information is relevant the drive's speed is 7200 rpm but I couldn't find any information (including Seagate's own web site) about its seek time spec.
Something else I noticed is that since I've installed the two 1.5 TB internal drives the fans inside my G5 have become more noticeable, raising their speed to a noisy level every now and then depending on what I am doing with my computer. This didn't happened before when I had only one internal hard disk installed (my original purchase configuration) and when I had (2) internal 400 GB hard disks installed.
Any ideas ?
Thank you in advance.
Joseph Chamberlain

Turns out I used screws that were too long above the optical drive which blocked it...
