How to wipe hard drive and keep OS?

Hi everyone...
I have a Powerbook G4 12" that was loaned to me. I'd like to wipe the harddrive to "out of the box" condition and keep OS X. I do NOT have the original disks that came with the laptop.
Since I'm a noob to Mac, what's the best way to format and/or wipe the drive of all the previous users junk and start over without bricking the laptop (since I don't have the original cd's)??
Thanks in advance for any advice/suggestions!!
Jim

How To Wipe Hard Drive and Install Mavricks.

Hello,
So I want to erase my hard drive completely and install mavricks back on to it. From reading other articals some said that if your computer originaly came with Mountain Lion (mine did) that you DON'T need a install disk. So now im lost in the confusion. What I want to know is how to completely Erase The HD and istall Mountain Lion Again. The way Apple told me to do it was after I click erase on the HD (throught DU) a window would pop up and ask if I want to reinstall Mountain Lion. Is that true?
(One more questing aside from the topic is, can you install a OS from Flash Drive.)
Thanks

How do I backup my iPhoto Library to an external hard drive and keep my photos grouped by their events?

How can I backup my iPhoto Library to an external hard drive and keep my photos grouped by their events?

I have attempted to make sure my iPhoto library has been backed up on the external hard drive and that it is safe to delete some events from my internal hard drive
You need to think this through.
Time Machine is a back up application. It keeps a rolling back up of the data. It's called rolling because it means you can revert to the data you had on a specific date and time. But that's not eternal, and as time goes by, and your drive fills up, older backups are deleted. So if you delete Events on your Mac they will - eventually - also be deleted from the Time Machine back up.
If you wan tot archive data hendon't use Time Machine for that job. Here's how you might archive an iPhoto Library:
Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
Now you have two full versions of the Library.
3. On the Internal library, trash the Events you don't want there
Now you have a full copy of the Library on the External and a smaller subset on the Internal
Some Notes:
As a general rule: when deleting photos do them in batches of about 100 at a time. iPhoto can baulk at trashing large numbers at one go.
You can choose which Library to open: Hold down the option (or alt) key key and launch iPhoto. From the resulting menu select 'Choose Library'
You can keep the Library on the external updated with new imports using iPhoto Library Manager

how to wipe hard drive bc selling computer and want all passwords/personal info gone?

You need to boot the computer from another source, e.g. a CD or an external drive. Then run Disk Utility, select the drive you want cleaned up, and run Erase. Note the security options: "write zeroes" will erase the drive completely.

I am not much of a computer technician. I bought a time capsule thinking I could use this for an external hard drive and keep my MAC hard drive free. Was I mistaken? One I back everthing up on the TC, can I delete everything off of my MAC?

TC was designed to backup your Mac. The TC literature is pretty clear about this:
If your Mac's hard drive has a problem....it will sooner or later....you can use your backup on the TC to rebuild your Mac.
But.....if you move all of your data to the TC from your Mac....you only have one version of that data now, and it is on the TC.
Have you thought about what will happen when....not if....the TC has a problem? Since the only version of your important data was on the TC, and the TC has failed......you lose all of your data.....because you have no backup.
A much better plan would be to add a USB or FireWire hard drive and connect it directly to your Mac. Move the data on your Mac over to the hard drive.
Then, the TC will backup both your Mac and the hard drive. So, you have original data on on one drive and backups on another drive.
That would be a minimum backup plan. Most of us have more than one set of backups.

Ios upgrade stopped my external hard drives and keep changing my laptop keyboards

Latest ios upgrade stopped my computers from contacting and saving in my external hard drives and keeps changing my laptop keyboards everytime I turn it on. Please Apple solve this because I know that many people suffer from this. If you do not I will stop my almost 30 year old use of Apples.

iOS has nothing to do with devices connected to your computer. It also has nothing to do with your keyboard. What have you done and when?

How can I wipe hard drive and do a clean install of Mavericks?

I have a 2012 MacBook Pro that is terrible sluggish, probably from upgrades and semi-deleted Symantec software. I want to wipe the hard drive and do a clean install of Mavericks. I have all files backed up, and can reinstall software.
I think there is a way to do this with Disc Utility? But don't know how. Advice welcome

If you have Yosemite installed and want to reinstall it, do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Reformat the drive using Disk Utility/Erase Mac OS Extended (Journaled), then click the Option button and select GUID. Then re-install the OS.

When you reboot, use Setup Assistant to restore your data.

How to replace hard drive and transfer everything over?

I've looked everywhere but am unable to find a definitive guide on how to do this.
Currently I have an early 2011 MBP that came with Snow Leopard and upgraded to Lion later. It has an HDD and I want to replace it with an SSD and transfer everything over to the SSD. Considering Lion created a Recovery partition (and there is also an EFI partition), I'm confused on how to do this the best way to basically copy my current hard drive to the new SSD.
The best I've figured out is to connect the SSD with a SATA-USB cable, use the Lion Recovery Disk Assistant ( http://support.apple.com/kb/dl1433 ) to create a Recovery partition on the new SSD, then, booting into Recovery, install Lion on the new SSD, and then use Migration Assistant to transfer all my files over.
Is there a simpler or better-explained way to basically copy my current hard drive over to a new SSD and then remove the HDD and use the SSD?

How to replace or upgrade a drive in a laptop
Step One: Repair the Hard Drive and Permissions
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, Leopard or Snow Leopard.) 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.
Step Two: Remove the old drive and install the new drive. Place the old drive in an external USB enclosure. You can buy one at OWC who is also a good vendor for drives.
Step Three: Boot from the external drive. Restart the computer and after the chime press and hold down the OPTION key until the boot manager appears. Select the icon for the external drive then click on the downward pointing arrow button.
Step Four: New Hard Drive Preparation
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your new 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. 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.
Step Five: Clone the old drive to the new drive
1. Open Disk Utility from the Utilities folder.
2. Select the destination volume from the left side list.
3. Click on the Restore tab in the DU main window.
4. Check the box labeled Erase destination.
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 old external drive.
Step Six: Open the Startup Disk preferences and select the new internal volume. Click on the Restart button. You should boot from the new drive. Eject the external drive and disconnect it from the computer.

Run itunes off external hard drive and keep settings

I have an imac which has my consolidated music library on it. I also have a macbook which i use while traveling. My itunes is about 130 gigs, which is fine on my imac, but too big for my macbook. in the past what i have done is just put everything on my 80 gig ipod, and then do the manual setting in itunes so that, if i get new music while traveling, i can put it on the ipod. anyway, that ipod was stolen and now i have a nano. So what i want to do is somehow copy my itunes from my imac onto an external hard drive, and then run itunes off that from my macbook. the point being to have my whole music collection there. The problem is that i cant seem to keep all my ratings, play counts and settings and stuff, the macbook doesnt recognize the setting file when its on the hard drive. Is there a way to do this? I tried changing the iTunes music folder location to the folder on the hard drive, but that did not make the songs appear in itunes on the macbook.
In addition, what id like to be able to do is, when i come back, copy the itunes from the external back onto my imac with all the new ratings, play counts, and music.

Can I partition a hard drive and keep files on separate partition?

That is, can I partition a hard drive and have the system software on one drive, and everything else on the other? That is, have the system software on one drive, and on the other have pictures, music, documents, and all other files other than the system software? Thanks. David

Hi GK1951, and a warm welcome to the forums!
Great question, as a matter of fact it does... or would, but the Devil is in the Details as they say.
IME, OSX works best with 100+GB free disk space, so if that partition scheme cuts that down then you'll lose speed, but ony a few would notice the diff until you get down to 30 GB free space.
I can't say much, but my VM at the moment is 143.55 GB, I've been told that isn't a real number, but hey, it means something!
But there are so many factors affecting this that really, the only rule that seems to hold is Give OSX as much HD Free Space as you can & it'll be happy.
I imagine on the MacPro you could say use the outer Partition of several Disks... one for the OS, one for VM, one for APPs, etc. and gain the most!
Maybe these will help...
iMac/24"/2.4 GHz/4GB RAM/320 GB SATA drive, You can see that Cached values account for more than the Zone on the HD really.

Wipe Hard Drive and complete reinstall

It looks like I have a nasty little virus on my computer and instead of trying to clean it off I feel much better blowing everything away, reformatting the hard drive, and reinstalling windows 7. Is there anything special I need to know before I embark on this quest? I looked through the box and I don't see any installation discs or anything to aid me through the process or the reinstallation of the drivers. There are a lot of Toshiba drivers that I never used so I probably don't need many of them.
My laptop is a Satellite C655D-5057.

Jerry,
thank you so much for the quick response. There are a lot of different options to choose from, but I'm curious if there is one that will be the best option for me system? I think restoring to factory out-of-box specs would be great, but I worry about the issue not being eliminated. However I'm also wondering if reformatting my hard drive is too aggressive. This is our main computer so if I error on a side I want it to be the most conservative in nature.
Regards,
Scott

About to sell my macbook, how to wipe hard drive clean

I'm about to sell my macbook (I've upgraded) , how would I wipe the hard drive, the whole computer for that matter, clean of all websites I've visited, passwords etc?
Anything else you can suggest? Like clear all bookmarks,and in Safari pull down menu, I guess 'reset safari' and 'empty cache' too, etc?
And in Accounts under System preferences can I change the name? I see I can change the password, sorry I'm not too computer proficient...I hate to miss something.
Thanks all

Here's what you need to do:
1. Re-install Mac OS (don't choose an option that keeps the old files, wipe it clean!)
2. After re-installing, open Disk Utility, and run the Erase Free Space utility on your newly formatted drive. This will ensure that your old files can't be recovered.
If you want your personal data off of your Macbook, simply doing step one will NOT be enough!!! Erasing and deleting are two different things. (Step one deletes, step 2 erases.)
Also, what chipperz posted should work.

Replacing two full external hard drives and keeping Lightroom 5 happy. Help please!

I use two external hard drives for storing photos and Lightroom backups - I do not have any photos stored on my Mac. As a result, they are almost full (25000 images) and I need to replace them with two higher capacity devices. I don't really know how to do this and still keep Lightroom 5 'onside'. I guess that I'd have to sync my drives one at a time with the new ones using Chronosync. Then, I'm also guessing that if I name the new drives exactly as I named the old ones, then Lightroom would carry on accessing the images as if nothing had changed. Am I correct with this assumption? If anyone out there has a better solution for me then I'd be very grateful for the advice. Thank you.

I don't blame you..
Definitely get things working with the new drives before re-formating (or deleting files from) the old drives. And make a copy of your catalog too. That way your vulrnerable parts are covered .
But Lightroom was designed to be able to withstand drive name changes on Mac, or drive letter changes in Windows..., so the odds are in your favor .
Cheers,
Rob

Add WAV folders to library from external hard drive and keep them organized

My PC died, so I removed the second hard drive containing my iTunes library - which is all in WAV and Apple Lossless formats - and installed it in an external drive case. I want to keep that library stored on the external drive but add it to the iTunes library on the new PC (which is a laptop and doesn't have enough drive space). I used the iTunes "Add Folder to Library" command, and added the top level folder ("My Music"). I have iTunes set to NOT copy files when adding to the library, but it is set to keep iTunes Music Folder organized.
iTunes added all of the songs, but only organized (kept the artist, album and other metadata) the Apple Lossless songs. All the WAV files have song titles, but no artist or album information. There are too many songs to manually add that information (about 2500). Is there a way to add and keep that information, or automate the tagging process? I know that WAV files don't have ID3 tags, but I hoped that since there were organized in iTunes by the old PC that all the information would transfer through some miracle.
One more piece of information: I do not have the iTunes data files (preference files? - the files that keep track of playlists, ratings, etc.) that are stored on the C: drive of the old PC.

You can elect to have the files left where they are when you import. See
in the import pane.
However having said that Aperture will not be happy having the original files stored voulme that is formatted FAT.
Also how is the windows formatted drive connected to the Mac? Direct or over the network?
If its a network drive you'll have additional problems. If it is directly connected to the Mac why not just format it for the Mac?
