How to check my hard disk's speed (RPM)

What system utility or command would I use to check the official RPM of the hard disk (i.e. to see if it is 5,400 or 7,200 RPM)?
Thanks,
Alex

There's no direct way to read this out on your MBP.
Go to System Profiler (Apple menu > About this Mac > More Info button, click on Serial-ATA in the list on the left, you will see Model: with a model number to the right of it. Select that model number and paste it into Google to get your info.
Hope this helps...

How to upgrade the hard disk of the nomad jukebox

I read the FAQ of nomad on nomadness.net, I wanna know how to upgrade the hard disk of old nomad jukebox with a bigger one?
I also read a artical on tom's hardware about this,
http://www7.tomshardware.com/mobile/20000/mp3-3.html
but he gave a link
http://www.kuren.org/jukebox
that is not available. He mentioned that it need to clone the fist 65536 sectors from the old disk to the new one, but I have not the old hard disk( I bought a second hand nomad jukebox without the original hard disk). How should I do?
Does someone have the image file of the fist 65536 sectors from the old disk?
Thank you!

That was the old method before Creative published their Bootcode Flasher software.
Follow the instructions here:
http://www.nomadness.net/modules.php...ticle&artid=24
All files mentioned are available somewhere on Nomadness. Also check out the sticky thread in their JB section of the forum as it lists what hard dri'ves will work in a JB and which ones won't. I hope you haven't already bought your upgrade hard dri've.
I used the above method without any problems and now have a 20GB JB.

HT1338 how to format my hard disk

how to format my hard disk ....my mac book came with no cds

You do this either with a Mountain Lion install disc or drive, which you have to make yourself, or from the Recovery System. For the Recovery System, you reboot while holding down command-R. This boots from a (hidden) recovery partition that is on your hard drive; then you access Disk Utility and do your formatting that way. The Recovery system can do a new install of Mountain Lion from the internet from apple once you have reformatted your drive. Or you can make a ML installer disk from the installer files that you download for future reference.
Here's a page about Recovery mode: OS X: About OS X Recovery
and here's how to make your own ML installer disk: How to Burn OS X Mountain Lion to a DVD or USB Flash Drive..
BTW, you could have figured out all this yourself with a google search.

How to increase RAM & Hard Disk a form at run time can use?

Question: How to increase RAM & Hard Disk a form at run time can use?
Explanation:
I have a problem with a form at run-time. I guess this is due to shortage of RAM/Hard Disk. I want to increase these things so that the form can use more RAM/Hard Disk and it does not crash/cancel. The reason is that when I change/toggle TOOL --> Preferences --> Runtime, Buffer Records and Array Processing parameters, the problem is rectifies intermittantly. That is there is no fix combination of above-mentioned parameters to rectify the problem. After lot of attempts, it gets resolved but only temporarily. Next time I have to modify the form, I get the same problem.
Please help.

I am still waiting for an answer to the above question.
May be Oracle Corp. or anyabody, please guide.

My HP Pavilion dv7 posted the following message:smart check failed - hard disk 1

php pavilion dv7
windows 7
hard disk 1 failed smart check

SMART is a feature in the hard drive, read by the BIOS of the computer, that is constantly measuring the drive's performance against a number of normal parameters, like the time it takes to move data from one place on the drive to another, and how many times data has to be moved around because there are bad places on the drive that will not hold data. If the drive's measurements go outside the normal range it is a sign the drive is failing and that gets reported to you, the end user, in a SMART error message. Kind of like a "check engine" light. It is a nice way of saying it is time to back up the data and buy a new hard drive.

HT1331 How to connect external hard disk to airport time capsule and use it throughmy ipad ?

I Have connected an external usb hard disk to airport time capsule. pleasea help me to configure it from my ipad and use it from my ipad.

You need the disk formatted HFS+ on a Mac.. you cannot format disks from the airport utility and there is no hard disk utility of course on ipad.
Once you set it to share.. then you need to load a file app to the ipad as it has no ability to natively handle files.. check out filebrowser as a standard one.. but there are several available.

How to make the hard disk visible in a new admin account?

I created a new admin account, in order (hopefully) to solve some problems that I've been having with SPSS21 for Mac. But when I log on as a new admin account, my hard disk no longer appears on the desktop. It (and all the folders and files in it) are still accessible by clicking on the hard disk in the path bar in a folder, but it's annoying not to have the icon on the hard disk. I don't know why the icon for the hard disk does not appear on the desktop. Does anyone know why, and how to make it appear? Thanks.

Oh, my god! I'm so embarrassed that I couldn't figure this out myself, after being a devoted Mac user for three decades! It's so obvious! Thank you so much!

How can I erase hard disk if SuperDrive is broken (OS 10.6.8)?

I have an old MacBook running OS 10.6.8 which I want to recycle, but its internal SuperDrive doesn't work, so I can't use the install disk to do it. I tried plugging in Apple's external USB SuperDrive which I bought when I upgraded to a MacBook Pro which has no internal SuperDrive, but the external SuperDrive doesn't accept the disc; it's as if the old MacBook doesn't recognize the external drive. I'm thus at a loss as to how to proceed to wipe the hard disk. Any suggestions?
Thanks,
Scott

The newer version Apple USB Superdrive does not support use with older Mac products
that have a built-in optical drive; so that avenue is not a direct method. Other brands of
relatively inexpensive DVD+CD R/W USB drives can be used with system DVDs to boot
most later Intel-based Macs using the Apple DVD system media discs.
There also has been topic discussions in various locations online about methods to
use a firmware change to newer Apple USB Superdrive, that may work with older Macs
that have built-in optical drives, those which may have failed to function.
The change to the USB external Apple superdrive may void its warranty. I noticed a repair
page at iFixit.com showing how to swap the actual drive out of the Superdrive, and in the
added comments, someone had posted a suggested (but not recommended) method of
modifying the Apple USB Superdrive's ability to work with older unsupported Macs.
https://www.ifixit.com/Device/Apple_USB_SuperDrive (4 comment/questions, not definitive)
https://www.ifixit.com/Answers/View/23023/Can+I+use+the+AirSuperDrive+as+an+Exte rnal+Drive+the+Mac+laptops
So perhaps the idea may work, or it may not. Other less costly third-party somewhat
more disposable DVD RW USB player/recorders that can work & boot Macs have
been discussed in the ASC discussions. Several brands, a few links to online sites
that had them listed. Usually for under $50.
Good luck & happy computing!

How can I create hard disk space without emptying the Trash?

I moved everything in my Pictures folder into Trash, not realising the folder also had the iPhoto library.
So now all my photos have gone from iPhoto, though they are still in the Trash folder, which has not been emptied.
I have attempted to restore in two ways:
1) Through Time Machine (which has most but not all of the iPhoto library backed up, and
2) By dragging the iPhoto library from Trash into Pictures.
In both cases the restore action fails because during the process I get the message that the start up disk is running out of space.
One way to create space would be to empty the Trash, but I can't do that because I would lose the photos not backed up on Time Machine.
I was not aware of any space problems previously, so I wonder if something I have done in this process has filled up my hard disk? But in any case, the immediate problem remains - how to create space (which will hopefully allow me to restore the photo library), without clearing out the Trash folder.
Thanks for reading this, and any advice will be much appreciated.

The following comments are really off topic because unfortunately they come too late to help you in your particular case. They may even amount to venting.
The way iPhoto hides your photos in packages that are not readily accessible in the Finder—because you have to Control-Click and open the package to show its contents first—is the main reason I immediately delete iPhoto from my hard drive whenever it gets installed by an OS installation or upgrade. I hate the "Libraries" paradigm in Apple's Apperture and in Adobe's Lightroom.
I much prefer the Adobe Bridge paradigm which is totally transparent and instantly reflected in the Finder, just as any changes you make in the Finder is instantly reflected in Bridge.
After years of trying, I've given up trying to find somene's ear at Apple to let them know how unacceptable iPhoto is (on so many levels).
Similarly, I have disabled Time Machine on my Leopard boot drive, preferring to rely on SuperDuper, although my main working boot drive is a Tiger volume. Because of their intrusiveness, I've also permanently disabled Spotblight and the Dashboard on all my OS installs.

•I have just bought a Toshiba external hard disk to back up all my work from my macbook and its not working! I have checked the hard disk

its not working: (sorry for being so ambiguous), the computer recognises it, it comes up on my desktop, when i open it and try and drag a file across, it is unable to go into the drive, there is just a symbol indicating 'no' (i've read the instructions from Tosheba and there is no help). I have not partitioned the drive using the GUID partition scheme - i dont know what this means?!
