I'm about to sell my desktop, how can I make sure that all my personal information is removed beforehand?

I have a Mac os x and am about to sell it to update. I want to be sure that all my personal information, photographs, music, bank info etc is totally deleted and unrecoverable. How can I clean my hard drive ?

Simply erasing and reinstalling is not adequate. As others have suggested, you should use Disk Utility to do a secure erase before reinstalling. You also need to do some other things, like making sure to deauthorize the machine in iTunes and include the original Mac OS X install disk that shipped with the machine. For all the details, see:

BTW, people should not be pushing you to mark an answer as correct. When you determine that an answer is correct, you should mark it as such, but only when you decide.

I will sell my touch. how can i make sure that i dont lose any data but the buyer does not access my info.

i will sell my touch and get the new one. how can i transfer my apps and ID to the new one and erase my info from the old one?
thanks!

Yes. If you do it through the settings on the iPod and have an older iPod, make sure the iPod is charging either via a computer or wall charger. It can takes hours to erase an older iPod.

I have changed the email signature on my iPhone, when composing a new email the signature is there, however when I am replying to an email it is not, how can I make sure that the signature is at the end of every email I send?

Yes I know what you mean about it cluttering the thread and for personal emails it is better without the signature. However this relates to sending business emails from an iPhone so I need the signature present on every email.
I can't find anything in Settings so I was hoping someone may have some knowledge/information/experience regarding this problem.

How can I make sure that in RAM our sql server is not facing any mermory crunch issue?

The SQL server process always show RAM is highly used while its a default behaviour of sql server.

The best way to make sure you are not facing memory pressure is to use perfmon counters and monitor various memory counters
For SQL Server 2005 - 2008 r2 use below counters
SQLServer:Buffer Manager--Buffer Cache hit ratio(BCHR): IIf your BCHR is high 90 to 100 Then it points to fact that You don't have memory pressure. Keep in mind that suppose somebody runs a query which request large amount of pages in that
case momentarily BCHR might come down to 60 or 70 may be less but that does not means it is a memory pressure it means your query requires large memory and will take it. After that query completes you will see BCHR risiing again
SQLServer:Buffer Manager--Page Life Expectancy(PLE): PLE shows for how long page remain in buffer pool. The longer it stays the better it is. Its common misconception to take 300 as a baseline for PLE. But it is not,I read it from
Jonathan Kehayias book( troubleshooting SQL Server) that this value was baseline when SQL Server was of 2000 version and max RAM one could see was from 4-6 G. Now with 200G or RAM coming into picture this value is not correct. He also gave the formula( tentative)
how to calculate it. Take the base counter value of 300 presented by most resources, and then determine a multiple of this value based on the configured buffer cache size, which is the 'max server memory' sp_ configure option in SQL Server, divided by 4 GB.
So, for a server with 32 GB allocated to the buffer pool, the PLE value should be at least (32/4)*300 = 2400. So far this has done good to me so I would recommend you to use it.
SQLServer:Buffer Manager--CheckpointPages/sec: Checkpoint pages /sec counter is important to know about memory pressure because if buffer cache is low then lots of new pages needs to be brought into and flushed out from buffer pool,
due to load checkpoint's work will increase and will start flushing out dirty pages very frequently. If this counter is high then your SQL Server buffer pool is not able to cope up with requests coming and we need to increase it by increasing buffer pool memory
or by increasing physical RAM and then making adequate changes in Buffer pool size. Technically this value should be low if you are looking at line graph in perfmon this value should always touch base for stable system.
SQLServer:Buffer Manager--Freepages: This value should not be less you always want to see high value for it.
SQLServer:Memory Manager--Memory Grants Pending: If you see
memory grants pending in buffer pool your server is facing SQL Server memory crunch and increasing memory would be a good idea. For memory grants please read this article:
SQLServer:memory Manager--Target Server Memory: This is amount of memory SQL Server is trying to acquire.
SQLServer:memory Manager--Total Server memory This is current memory SQL Server has acquired.
8. Free List Stalls/sec – Number of requests per second that had to wait for a free page
9. Free Pages – Total number of pages on all free lists (free lists track all of the pages in the buffer pool that are not currently allocate to a data page, and are therefore available for usage immediately)
NOTE: If you have NUMA system don't use PLE to monitor memory condition it wont give correct value
From 2012 Onwards
Memory management has become easy from 2012 onwards as
Max server memory also allocated memory for requests which require memory >8KB
SQLServer:Memory Manager:Free Memory (KB)
SQLServer:Memory Manager:Target Server Memory (KB)
SQLServer:Memory Manager:Total Server Memory (KB)
For NUMA system its also wort monitoring each node.
Object - SQLServer:Memory Node:Total Node Memory
(KB)
Object - SQLServer:Memory Node:Target Node Memory
(KB)
Object - SQLServer:Memory Node:Free Node Memory
(KB)
Ideally if target server memory is less than or equal to total server memory there wont be memory pressure if target is > total it does not always means its memory pressure
BCHR would also give you good idea about memory pressure
If memory grants pending is frequently non zero there is memory pressure

I HAVE TO INSTALL A PRODUCT CALLED "KUDANI AIR " . FAILURE TO DO SO IS BASED ON ADOBE AIR , SO I AM TOLD . HOW CAN I MAKE SURE THAT IS THE CASE ?? HOW CAN I SOLVE THE PROBLEM IF THIS IS THE CASE ??

if you try to install an app that depends on adobe air, you should be prompted to download and install adobe air (unless it's already installed).
you can download and install directly so you're not prompted by that app, Adobe - Adobe AIR

I purchased three albums last week and only two of them were charged. How can I make sure that the third album gets charged in a timely fashion?

Well, thanks for feeling with me, patkosanke ... AND for your wise advice.
I did followed your advice immediately and erased all the service number as well as S/Ns.
Can you, however, give me any "direct number" through which I can get hold of someone and request for what you're suggesting?
I believe I had talked with the person by the name of "Charlie" (I think... I hope I'm correct...) when I was having the same problem with the last device. He was very kind and helpful, though I ended up getting the device that brought the same problem.
Charlie told me that if I had any more problems I should call him. But I forgot to take down his direct number.
Or maybe I should call the main office and ask for him. But my memory is questionable as to his name, and besides I don't even know his last name either. There could be more than one "Charlies" in Palm.
So, if you could somehow email me some direct number (other than the one that keeps on hooking me up with those people in the overseas who are answering the phone only to sympathize with & apologize to me but can only issue a false hope with the SRO#. More than once I was given the promise that the supervisor would call me back within an hour or two but I ended up calling back after I had been left hanging in the air all night long.) where I can talk to someone like I did with Charlie last time who can truly carry out the promise, I would truly appreciate it, patkosanke. ^^
Thanks

Thanks for your prompt response... will changing my password also stop the authomatic download of my new applications and music from downloading to the stolen phone?

If I am playing a song from my phone on speakers, how can I make sure that there are no interruptions like calls or notifications? My students are performing and it would be terrible if there was to be an interruption.

You could turn on Do Not Disturb. This would block all notifications and incoming calls.
Or just turn you're phone's Airplane Mode on if you're not streaming the music

HT1349 we both have the same Iphone, how can we make sure that we both have different account on the same network?

my partner and i have the same models of Iphone. how can we make sure that when she logs on to our home network, it recognises her phone and doesn't down load to my phone?

Did you try to rename one of them? iTunes: How to rename your device
iTunes remembers the settings for each phone when you sync, even if both phones are called "My iPhone".
So make sure to set it up like you want to, after that iTunes will do the rest.

How can I make sure that icloud deleted my stolen device

I got my iphone stolen about 2 weeks ago, and proceeded to send a deletion request next time the iphone was connected to wi-fi.
I forgot about the subject until yesterday when, while browsing through my pictures, I came up to a picture I didn't take... In fact, the picture was taken no where near my home town... So it must be the thief that took the picture and when the iphone conected to wi-fi, and beacuse the photo streaming option, I could see it on my new iphone.
So reading about the remote deletion option of the icloud, I read that the way to confirm that the device has been deleted is because you receive an e-mail confirming the deletion. However, I never got this e-mail... and before this, when I logged into iCloud, I used to be able to see the stolen Iphone, but now I cannot see the stolen device.
Please, can anyone tell me how to be sure of the deletion??? how long does it take to remotely delete the iphone?? Does the iphone have to be connected to wi-fi during the whole deletion process???
I'm very worried, because they obviously have access to all my information!!!
Thanks for the help!!

How can I make sure that Iphone does not remove IMAP emails?

Emails that I get first on my iPhone are not on my other computer later. Is there some setting to make sure things are not removed?

Check to see if the account is set up correctly. Al roaminggnome said, this is not how IMAP behaves. Unless...
If it is set up as IMAP, when you delete a message on the phone, it will delete it from the mail store on the server, meaning it will not download to other devices. That's the way IMAP is supposed to behave.

How can I make sure that a downloaded file goes to the left of the desktop

Hi all,
This may be a stupid question but I havent found the answer after much searching. Basically I like to have my dock on the right. And because of that, I life to have all the icons on my dekstop on the left. No problem so far. I managed to move the HD icons by making aliases and unticking the keep arranged option. So now all my desktop icons are on the left exactly where I want them to be. However when I download a file, that file shows up on the right of the desktop! I would really like it to just fall in line with the other icons, i.e. on the left.
You may think im being picky but the thing is, I download a lot of files, and what ends up happening is I get a column of files on the right, very close to the dock (so close in fact that their names are hidden by it). So it is quite annoying.
I would appreciate any help.

Hi kakeez,
If I were you, I'd create a folder named "Recent Downloads", place it on the left on my desktop, and set my browser's preferences to
"*Save downloaded files to:*" this folder.
Note that you can also play with the Finder's View Options (command+J) so that size of the icons combined with label position (bottom or right) make it look good and handy with the dock on the right.
That's what I do myself. I use icon size 40 and text size 11pt, with the label on the right.
With the "Snap to Grid" option checked, it all fits beautifully with my Dock on the right of my screen.
Tip:
One of the known factors of slowing down Mac OS X, is to have a lot of icons (no matter which) on the desktop.
So if you don't care about a beautiful wallpaper, free of cluttering icons all over it,
at least consider this slowing down aspect:
~ it is much better to create folders within the Documents, Pictures, Movies folders, or also at the top level of Macintosh HD or each User's,
and organize your work that way, so you can keep as few icons as possible on the Desktop.

How can I make sure that there is absolutely NO sharing of my library over any network (including whatever wifi I connect to) ?

- I don't want my library to ever be available to anybody.
- I want to be sure it doesn't automatically switch back to being available after some update or whatever
- I would like to know a few things about how often my library was available in the past, considering that I've only just figured out that it was.
Specifically, I'd like to know - was it available to other people connecting through the same wifi even when I had the application closed?
Thank you, potential question answerers.

It would help if you provided more information. I add hundreds of files to my library each year with 12+ years iTunes use. One duplicate per year = something you are doing is causing this. Realize if you drag a file from your anywhere on your computer except the iTunes media folder to iTunes, iTunes puts a copy of the file into the correct media library folder and adds the track to the library file database you see in the iTunes window. If you drag the file to iTunes again it will do it all again = duplicate.

I'm about to sell my desktop, how can I make sure that all my personal information is removed beforehand?
