Software :: OSX Reinstallation - Necessary To Erase Entire Drive?
Apr 30, 2008
It looks like I have to reinstall my OS. Does anyone know if you 'must' erase your drive when reinstalling OSX? I don't even know if my drive is there still but want to know in case I can save all of my data that has not been backed up.

The Western Digital hard drive inside of my MacBook has been loud lately, so I requested that they send me a new one. I received the new one, and I need to send them my old one within 30 days. Now, I'm faced with the dilemma of erasing the hard drive so my information won't be in the hands of someone else. So, what is the best way that I can erase the entire drive before sending it over to Western Digital?

I have an old iBook that I just want to completely wipe clean and install windows XP on (I know...blaspheme). Before people start questioning why I would do such a thing...it's only because I need the laptop for DJing in which I have an external sound card that only works with Windows. The main problem is that the CD drive doesn't work so I am uncertain how to go about erasing my hard drive and installing XP via USB.

I am looking to copy one hard drive, partitions and all, to another drive, while maintaining the boot integrity of all bootable partitions.
Here's what I have:
Two 320GB HDD's, one that I am booting from, and one to copy to. It has two partitions - one containing OSX, and one containing my Boot Camped Windows 7 Ultimate install.
How can I copy the entire drive to another drive, block by block?

I've been having problems booting into my OSX partition. At the time it started I wasn't using my Macbook Pro (Late 2009) very often so whenever I needed I just booted up into my BOOTCAMP partition. Anyways, I decided to finally stop being lazy and do a clean install. There's nothing on either partition of the same hard drive that I want. I put together a bootable USB drive and boot from it. From here I go to the Disk Utility and try to erase the entire drive. It gives me this error: URL....
Now, that's not a screenshot from my mac but its the exact same error. Anyways, I've tried to find something on point but I just can't. Some posts have stated that the hard drive is broken, but if that's the case why can I start up the BOOTCAMP partition of the exact same drive flawlessly? I can even manipulate files on the OSX partition from Windows 7.Â

I have a 2 year old external HD (Samsung HD753LJ), which has 3 partitions. One for my TM backups, the other with just straight data and a FAT partition for WIn compatibility.
This evening while reading some files off the non-TM partition, I noticed the drive 'ticking' and then got a read error.
I ran up Drive Genius-2 and it found 3 bad sectors. I'm not too worried about the file as I can replace it, however I was unable to find a way to repair the sectors without destroying the entire drive's contents.
My questions are as follows:
How can I do a non-destructive sector repair without losing the entire drive?
If yes, can anybody tell me what software I should use?
Should I be replacing the drive even if only 3 sectors have gone bad?

I have an iMac (2009 acquired) 3.06GHZ - Mac OSX 10.6.8 - 4GB mem.
I am experience CD/DVD drive problem with some CDs with photos: The drive starts accessing the disk
but at some point (say, midway through a 300 pic cd) seems to stop recognizing the presence of photos on the disk.
At that point, Preview cannot access such "unrecognized" photos and Icon vew does not show such "unrecognixed" photos. It is as if the drive is not able to explore the entire disk.
Same seems to happen when I write to a blank DVD disk: some material ends up not being written to disk.Â

I have a hard drive with bad blocks. I backup the data and various other part of the drive to the cloud. However, I want to make a backup of the entire disk but want to be able to access all the data individually as I want to transfer the data onto a new HD and the applications/fonts etc onto an SSD. Also, is it advisable to literally copy the contents of the Applications folder across to the new SSD drive or should they really be re-installed one by one (yikes!)?

Reading on the microsoft support pages it says you need to boot from the startup disk to do the system re-install, but I can't seem to do this. I tried to just leave the disk in, then restart in windows, but it just spit the disk out. Then I tried leaving the disk in and holding down the option key and clicking on the startup disk, then all I got was the blank windows screen with the line in the corner. how to do the reinstall?

y question is : should I try to reinstall the entire operating system on to the g drive and boot from and use that as the main drive, or should I just learn how to configure all my programs to save to the g-drive. I have tons of dvds with video and data on them because I ran out of space long ago and so I am finally going to have some space so I am excited about having the g drive.I ask these questions because I have read in the past that the internal mac mini drives actually slow down the system, however I dont know if this is still true, I know the bus speed is faster etc in the new ones

I know how to fix this problem, I was just wondering if anyone knows WHY it happens.
I have a network drive that I use on my iMac and every time it's nearly full, my WHOLE machine becomes unusably slow. I mean, even opening a finder window can take up to a minute. Just deleting a couple of files off the network drive will fix the problem. Unfortunately, it can take up to an hour just to delete a file because everything is so slow, including the actually deleting of the file.
I don't have an system files on the drive, just a bunch of video files and personal documents.
I was just curious why the network drive being slow would impact the whole system? It just seems weird to me.

Currently I am running Windows 7 Ultimate (400GB) and OSX 10.6(100GB). I mainly use windows 7 (don't ask why). Anyways I am wondering how I can create a bootable backup of my entire drive (both partitions) form my windows side. Also the software should be able to handle incremental backups, so that the backup don't forever and ruin the backup drive. I have tried a few different pieces of "cloning" software but they don't seem to handle the GPT partition (the efi partition?) very well. I don't know much about partitions. My goal is to create a fast (incremental) bootable backup so if I plug my backup drive in and hold option down four (2 windows and 2 osx) bootable partitions should appear. If that is not possible switching the hard dives is also an option.

I was trying to do some tasks in Windows 7 in VMWare fusion and it was a little laggy, so I shut down the VM and restarted my mac. It took a little longer to restart than I'm used to, but when it came back on 99% of my main hard drive is now gone. All my bookmarks in safari, user accounts, most preferences are still here but all files are gone. How could this have happened and is there any way it can be reverted without a time machine back up? It's a mid 2010 21" iMac i3 8GB ram with Lion installed all newest updates have been done prior to this happening. I don't even know what to do, so much has been lost.

iMac, Mac OS X (10.7.3)

I just had to re install mac os x 10 but after I did I was not able to log in as it seems that my user details have been erased. So I started up from the cd rom again and navigated to the password utility there I tried to change my password but the only user option was system administrator (root) nothing else!.

Every time I back up to my external drive Time Machine automatically backs up the whole hard drive which is very time consuming. This happens every time I back up. It's supposed to only add new files, not do the whole thing. Haven't changed user name or any of the things mentioned in other discussions that will cause this. Does some setting need to be changed?

I have a 500 GB external drive that uses FireWire. Recently Time Machine started deleting several backups to make room for new ones. It now says the oldest backup is May 4th, 2012. I thought this sounded like a problem. When I looked into the details, my iMac now thinks my hard drive has 400GB instead of 500GB.Â

Recently I bought 2 identical WD Scorpio Blue 1TB hard drives for my macbook pro 13 inch 2010. My aim is to replace the internal hard drive with one of the two I just purchased and use it as my system drive with Lion, Windows and Data partitions. And for the other hard drive I want to use it as a full disk back up for the internal drive (now 1TB hard drive). After I was done with setting up both windows and mac and data transfer, when I booedt into the recovery partition from the internal drive to clone the drive to the external drive, the disk utility gave me this error (Could not validate source - error 254). I also tried using Carbon Copy Cloner but it only could clone partitions, not the entire drive. Yesterday I downloaded a copy of Clonezilla. It worked fine until it had to clone an exFAT partition (my data partition). The exFAT partition appeared as 'RAW' partition in clonezilla. As a result, the whole partition appeared to be full and clonezilla had to copy every single blocks of data in that partition and the estimated time remaining was about 30 hours. So clonezilla is out too. Just want to ask if there is any program/application (bootable or not) which allows can do a full disk clone to an external hard drive.

I recently tried to install a back-up copy of Leopard onto a USB hard drive, as a precautionary measure if my drive ever did die. I had partitioned my drive into 3. One for the Leopard Boot (Mac OS Extended Journaled), one for Apps (Mac OS Extended Journaled) and one for files (FAT 32).
The installation pooped out on me, probably due to the amount of free space available.
Earlier this week, I decided to reformat the drive into 1 partition. Unfortunately I ran into a spot of bother....

I just want to know, is it OK to erase the whole internal drive (not 'Macintosh HD' partition) and install a clean Lion? Will all the partitions be lost after erasing the drive? And when a new Lion is installed, will it automatically create two partitions: "Macintosh HD" and "Recovery HD"?

So I currently have a late 2008 MacBook Pro. I may be getting a new iMac for Christmas. My question is, is there a way to basically transfer all of my files/programs/etc. to the new Mac without having to reinstall everything? The iMac will become my primary computer, and the MBP will become kind of a sitting on the couch/travel computer. This is the first time I will be upgrading Macs, as the MBP was my first non-PC computer.
The MBP is running Snow Leopard already.

I am going to be selling my trusty 12" PowerBook G4 to a friend soon, and putting the money I get from that towards a last revision 15" PowerBook G4. After I transfer my data from the 12" to the 15", I want to completely and securely erase my hard drive. The thing is, I don't know how to do this! I've never formatted/erased a hard drive before.
