OS X :: New Erase And Zero Out Sectors Option In SL?
Sep 10, 2009
did anyone else notice that if you boot the SL disc from the DVD and go into disk utility, there is an option to Erase and Zero out sectors?
I'm just wondering if this solves the performance degradation issue of SSD's over time. Has anyone tried it and benchmarked the results before/after?
In theory it seems like it would work (albeit at the penalty of losing all data on the SSD).

I have tried numerous times to restart the PC with the Leopard disc in my DVD drive and it comes up, after I press C upon reboot, but no matter what I try I cannot get the erase and install option to ever show up.

with the new macbook pros, when I follow these steps I dont see an "erase & install" option anywhere. When it says select the destination, only my harddrive appears. When I double clicked on it, an option box came up but nothing said "erase and install". Am I missing something: How to 'Erase and Install' on Macintosh computer that came with Mac OS X v10.6 Snow Leopard and later Part One: Installing the operating system
1. Power on the computer.
2. Insert the Mac OS X Install DVD into the optical drive.
3. Restart your computer.
4. Hold down the Option key while the computer starts up.
5. Select the OS X Install DVD and click the arrow underneath it to boot to the install DVD.
6. When the Mac OS X Leopard Installer screen appears, click Continue.
7. When the license agreement appears, click Agree.
8. Select the destination and click Options.
9. Select Erase and Install and click OK. The arrow on the destination changes to a green and a note on the bottom of the screen indicates you have chosen to erase the volume you selected
10. Click Continue. An Install Summary screen appears.
11. Click Install. A status bar appears on the bottom of the screen while Mac OS X installs.
12. An Additional Information screen appears, advising you that you operating system has been installed. This screen advises you that the bundled applications have not yet been installed. Click Continue.
13. An Install Succeeded screen appears. Click Restart.

Is there a way to check my hard disk for bad sectors? I dropped my MacBook off a 2nd floor balcony onto grass and I don't want to get a nasty surprise sometime in the future when it tries to write to a bad sector.
Please don't say fsck because there's nothing wrong with the file system because I dropped it when it was off.

I use Paragon NTFS to access a firewire/USB2 1TB drive. I recently noticed that some files on it, videos', won't copy to another drive. Using ViSTA and Firewire(Boot Camped) the Vista OS says the disk is unreadable, but the Mac OSX(10.5) just hangs after so many seconds. I've identified 9 large video files I really want back, what do you guys suggest for file recovery? I have Vista Ultimate 64bit and OSX 10.5

does fsck or fsck_hfs scan a hard drive for physical errors also or is it only for the file system layer?

I want to upgrade one of the two 500GB HDD I currently have in my MBP 5,3 with a 1TB one. Given that I had good experience with WD, I am looking at their offerings. While their standard WD10TEVT is hardly available around here and if it's much more expensive (for what ever reason), I am interested in the WD10TPVT. Now that HDD has the new Advanced Formatting with 4k sectors which seems to be only a problem for WinXP. But could any Mac user share its experience with that HDD? Is it gonna work the same with Time Machine, backups, file transfer between disks or can issues occur when files are exchanged/transferred between disks with different sector sizes? Only want to upgrade one of my HDDs for now, so is there any preferable setup (in terms of which HDD to have the OS and which the files)?

I upgraded my MBP internal hard drive to a Samsung 1TB and it crashed for the 2nd time (will never buy another Samsung). So this time, I purchased a WD and migrated my system to the new drive sucessfully. I just wanted to see if anyone knew if the migrate function simply copies files or if it copys sectors of the hard drive. Basically I just want to know if Mac Migrate will copy the crap from the Samsung drive that might cause my new WD to act up - or if that's possible?

MacBook Pro, Mac OS X (10.6.8)

I want to start afresh on my HD, i.e. reinstall from original disks and use Disk Utility to secure erase (via Erase & Install).I've read articles about pros and cons + how to do it. So I think I know how to do everything.However, from my reading I gather that Zero Erase is a single pass random erase whereas 7 Pass is secure erase (and there is a 3 Pass secure erase option nowadays)?That got me wondering - does 7 Pass secure erase make 7 x single passes over the entire disk?If it does, then when the blue bar has extended a bit over a third of the way across the progress monitor (that little bar that indicates time left) it should have made 3 passes, which would be equivalent to 3 pass secure erase?Is that an option?Is it possible to stop part way through an erase (which is part of E & I)? My original disks 1 and 2 have OS X 10.4, with OS X 10.5 included as complimentary 3rd disk (because OS X 10.5 was just released at that time).I gather I need to erase with disk 1, then install disks 1 + 2, then install OS X 10.5.

I ran my usual check on the mac drive via "Verify Disk" option. It came up with "needs repair"...etc., and told me to repair it. I did a command r during boot so I could do a repair, and the software told me "your mac drive seems to be ok"??? Some kind of glitch, or need I worry about it at all?

I just followed this link here [URL] to install my SSD and I foolishly did the Zero Erase. After searching through macrumors, it seems that I have killed my drive. Is there any form of redemption? Corsair F60 on a brand new MBP 15inch

I've had my iMac since early 2008 (2.8GHz, 4GB RAM, nice NVidia card) and it has ran great until recently. Things seem slow, and take a bit too long to open. Even worse is that its performance is inconsistent. Sometimes iTunes can take 6-8 seconds to load, and sometime 30 or more. I had concluded that this is due to my hard drive being almost full (320 gigs). However, I erased about 50GB of info, and it still performs about the same.
The bump to Snow Leopard helped a bit, but the performance still isn't near where I'd like it to be. I also just installed 4GB of RAM. So a new idea is to just completely erase everything and start over. I have a time machine backup of all of my info, and I would selectively add old information to the newly formatted drive (things like movies, photos, apps). However I have two problems in doing a full erase (or whatever the technical term is).
What happens to preferences and the such? I have my iPad and iPod touch synced to my iMac and I don't know how that would affect them after I tried to sync them after the erase. Also, if I load all of my photos back into iPhoto, will events and albums need to be reconfigured? What happens to my Windows Vista partition? I have a 30GB partition for Vista, and what would happen to it? Would OS X be smart enough to not touch it?

I have a 2009 MacPro. SSD has the boot and apps from the 2nd Optical Drive. Original 1x4TB drives are in Raid 0 and have all the data (home folder etc). They also have the original OSX and apps which are no longer in use since everything boots off the SSD.
I want to erase the 4 raid drives (disconnect raid all together) (data all backed up to a drobo). Use first 3 drives as new storage and the 4th as bootcamp.
however, when I try to erase the raid data drives, it says it can't unmount the disk (yes, have no apps running other than disk utility from the SSD apps)

I need to repair my hard drive but the Disk Utility won't work.
I found out that I can insert the disk it came with and install the OSX and then run disk utility and do the repair.[I think it's called doing a clean install]
So I insert my disk and try and install the OSX and it's telling me I need to erase everything on my computer and then I can install it because there's a newer version on OSX on it.
[My MBP is 2 years old so I think I have Leopard or Snow Leopard]
Is there any way I do it without having to erase everything?
If I do end up having to erase everything would it be possible to put it all on my Seagate, that currently is holding stuff from my PC? How do I do that?

I have a 2007 Blackbook with Snow Leopard installed. I tried to install Bootcamp but it said that I had to do an erase + reinstall first. I booted my mac up from the OS X disc, got past the language menu, then got a pop up stating "MAC OS X Cannot Be Installed." I can't click on Disk Utility or anything else on the menu bar. How else can I erase my HD?

I am having trouble erasing DVD+RW discs. When I insert a used disc and try to erase it in Disk Utility, the process seems to complete almost immediately, ending with OS X asking me if I want to mount the inserted blank disc in Finder. However, if I eject the disc and put it back in, everything is still on there. (detail: When erasing, there is usually a short interval where a striped progress bar is shown, after which a "normal" progress bar is slowly filled as the disc is erased. However, for me only the striped progress bar is shown--the "normal" progress bar is skipped--and then OS X says erasing is done.) If instead of ejecting the disc I choose to go ahead and burn something as if Disk Utility has actually erased the disc, I get a laser power calibration error.

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 have a huge external drive. I just deleted some things that I don't want anymore. But I still have a lot of stuff I want on the drive so I can't format it and move on. I have to keep a lot of files on there.
How can I erase and zero out the free space that is left when I deleted those files?

I recently purchased a MacBook Pro. I previously owned a MacBook and have a bunch of personal info and preferences on it. I used migration assistant about a month ago. It worked pretty well but some of my apps weren't there or weren't functioning well. My new MBP seems like it is unorganized. I want to erase my HDD (just install OSX again, right?) and start fresh. Is there another way to transfer my info over to my new MBP? Maybe pick and choose EXACTLY what I want transfered... I don't think migration assistant gave me an option to select individual apps.

I seemed to have had a keylogger or virus on my MAC. I had to reformat it. I used google, I am relatively new to MACs, and the method I used was inserting the disk 1 while holding down the option key. It is reformatting as I type this. My question, does it completely erase everything? I know with PCs, a simple reformat like this does not always remove all the problems.

Every time I try to erase music from my USB Key or Phone.
You can see that the music or files have been erased, but it doesnt free up and space. When you pop the USB Key into the stereo or play music on the phone, all the files are there.
I have to go through the Disk Utility option to erase stuff, but this erases everything. When you erase on the PC, everything is fine.
