Erase MacBook Pro hard disk. How? "Erase Disk" is grayed out.

I want to use Disk Utility to erase my HDD on MacBook Pro. BUT the Erase disk is greyed out. I checked user account and unlocked the padlock for my Admin account. What next please?

Remember to press the 'C' key to boot on the Snow Leopard disk (or set the boot disk from Preferences -> Startup disk)...
Also, if you want to install the OS on an external Hard Disk, format it GUI (check the help for instructions).

Well then when you erased your hard drive, your erased the Recovery partition, also.
Use Internet Recovery to either restore from your Time Machine backup or reinstall the OS if you don't have a TM Backup.
It will install the OS that shipped on that Mac. You can then upgrade via the App Store.

My MacBook Pro Hard Drive recently gave me the gray folder with the question mark of death. Even as

My MacBook Pro Hard Drive recently gave me the gray folder with the question mark of death. Even as a Mac Newbie/Novice, I successfully installed a new hard drive and the OS (10.6.8) software from my installation discs. I have, however, lost the ability to play video using the spacebar and I have no idea on the steps necessary to correct this seemingly simple technical blip. .Here's my system overview:Model Name: MacBook Pro Model Identifier: MacBookPro6,2 Processor Name: Intel Core i5 Processor Speed: 2.4 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache (per core): 256 KB L3 Cache: 3 MB Memory: 4 GB Processor Interconnect Speed: 4.8 GT/s.
I am using the Premiere Pro CS5 NLE (with the 5.0.4 updates), and I have tried to reinstall the software (which is actually the Production Premium package) several times, but I still cannot use the spacebar (or any method) to play any of my imported videos.
PLEASE HELP in any way you can!
Prior to having to replace my hard drive, my software was working just fine. No problems at all. But now, it seems that I can't get it to play whatever type of file I import.
Again, I am a newbie to the Mac, so any and all correctional/repair assistance needs to be expalined as if I were a child : )
I would hate to try to revert to considering the sophmoric Final Cut Pro X editing software package, but I've got to do something to be able to get back to my editing activities.

@FatMac the internet recovery doesnt work. It goes into recovery mode and then when i try to reinstall it cant find a disk to install it to. So what would be a good choice to take now?
Recovery Mode presents you with, among other things, Disk Utility. When you open that, if the internal shows up at all, first try to "Repair DIsk." If that doesn't work but if the "Media" line is present, try to format and partition it with a GUID partition table (understand that you will be erasing the contents of your internal). Then try to reinstall the OS. If that doesn't work, and since your Retina MBP didn't come with a DVD drive or DVDs, you'll need to try a hardware test using these instructions from Apple (short version: shut down, press the power button and hold down the "D" key). If none of those things work, let's hope you either have AppleCare or your warranty has some life left because the SSD in your rMBP is proprietary and expensive. You'll need to bring it to an Apple Genius for evaluation.

I accidentally quit my CC on my Macbook pro and now the cloud icon is grayed out and every time I hover over it with the mouse I get the spinning beach ball of death on the icon. I have no idea how to open it because when I use spotlight search to open it

I accidentally quit my CC on my Macbook pro and now the cloud icon is grayed out and every time I hover over it with the mouse I get the spinning beach ball of death on the icon. I have no idea how to open it because when I use spotlight search to open it it gives me a message saying "Creative Cloud is not open anymore" help!

Since you didn't include any pertinent info such as the Mac model and OS version you are running, here is some general information:
Mac OS X: Gray screen appears during startup
Depending on which OS yours came with originally - and which OS you are now running - you would either need your original install disks - you can call Apple for replacements by giving them your serial number. Or you may be able to reinstall the OS by using recovery (again, depends on which model/which OS).

How can i format my MacBook Pro hard disk and recover my data from time capsule?

Hello,
My MacBook Pro is running slow, more and more. Everything started with the "upgrade" to Lion.
Can I re-format my hard disk and recover from Time Capsule only the data and applications I really need (including Snow Leopard as OS, maybe)?
Thanks

The problem is that it is a Western Digital 3.5 inch internal hard drive housed inside a hard drive caddy. So the only way to connect it to my computer is through a dock.

HT4718 I tried merging the empty space on my Macbook Pro Hard disk but it says that there is a problem with my disk and i need to reformat it. What should i do to keep my applications and software + files?

Hi All,
I was given a macbook pro with parallel windows, and later windows was remove but hard disk space is greyed out and could not be merge and when i run a 'verify disk' it told me to reformat my OS. The nearest service centre is real far away from me and i hope to solve this on my own. I need to keep my applications and files, how do i do so? As some of these applications was given by my company. I need help on keeping my files and reformating.
Thanks in advance.

Get an external drive and make a clone of your internal, erase the internal, set it for 1 partition (OSX Journaled) and restore the clone.

Can I upgrade MacBook Pro hard disk drive next year?

Hi there! I'm new to the Apple Support Communities!
I am going to buy a new 13" MacBook Pro, 2.5GHz. I am going to buy the base model, with a 500GB 5400 RPM hard disk drive. Right now, I can't afford a 256GB solid-state drive, but I'll have enough for one by later next year. So, I will have done some stuff on my Mac by the time I can upgrade it. I know how to install the drive itself, but how do I transfer my information?
Here are the issues:
1) I don't know how I would make it so I could boot from an external USB.
2) And I don't know how to get all my personal information from one drive to the other.
For "2", I think I could back up my Mac to a hard drive with Time Machine, and then restore from a backup. But Time Machine couldn't back up the whole OS, right? And what would the procedure be anyway? Just turn it on when I'm done the upgrade?
If someone who has done this before could provide step-by-step instructions, I would really appreciate it!
Thanks,

Yes you can replace the hard drive at any time. Purchase a replacement drive from any store you like - newegg or mcetech are good stores (among many others) - and when you purchase the new drive, also purchase a drive enclosure. Then download a program called "super duper" and follow the instructions to use that software. When your drive arrives, put the new drive in the enclosure, plug it in to your computer and run "super duper" with the option to "make the drive bootable" and let it finish. What it's doing is copying your drive onto the new drive. Once the copy is finished, you can shut down your computer, remove the drive, install the new one, and put the original drive into the enclosure. Now you have an external hard drive that is repurposed instead of throwing it away. Keep that drive intact for a few weeks without erasing or adding data to be sure you are happy with the new drive and how it performs. After that, use the drive to store files, backup the internal, transfer stuff, whatever.

Replacing MacBook Pro hard disk

Hi to all. I found on the web tutorials about replacing hard-disk on the MacBook but nothing about MacBook Pro! Is this operation very difficult or much more difficult that on the MacBook? Anyone is able to indicate me haw to do or a tutorial? I would like to replace my 80GB with a 160GB HD.
Thank you to all of you!

sorry I can't offer any direct advice. but I think the reason why it's easier and there is user info on how to swap out the drives in the macbook is because they are the first apple notebook to have a drive designed to be replaceable by the user, AFAIK. it's ironic, but the macbook pro is not designed with a user-swapabble drive, so that's prob why you're having trouble finding a guide to do it. also be aware that opening the machine voids your warranty. that said, I have heard of people that took their MBP in to a computer service place to have the drive replaced, so if you don't find out how to do it yourself, you could try taking it somewhere. btw, my grandmother came from varese..

My macbook pro hard disk showing S.M.A.R.T failure, but the partitions inside are okay

My macbook pro had been facing booting problems intitially. Getting stuck at Apple logo and showing a progress bar. On reaching end of the progress bar, the system shutsdown. I'm able to log in to Recovery HD/Single user login mode. Backed up all data to an external drive. Then cloned the Macintosh HD image to one partition. The cloned image is also showing the same problems - Cannot Verify/Repair. After backing up data, I've erased the Macintosh HD partition, which is blank now and has no errors. But the parent node (disk0) is showing S.M.A.R.T failure.
A week back, I was having problems with Google Chrome and Safari getting stuck and not responding issues repeatedly.
Welcoming expert opinions to get thru this.
Thank you.
Regards
Naveen

It's nothing like that. You have suggested very good steps for all my queries in fact.
But I'm a bit reluctant to accept that the HDD has failed physically. Even if the SMART error shows reallocated sector count problem, this could again be Hard and Soft error i suppose. Since the data is not critical to me, I want to experiment other ways before disposing.
Also, as of now I'm able to use my Laptop as it used to be before. It could very well fail shortly.
99% threads suggest to throw away the HDD at the earliest. And so, there is nothing wrong in believing you.
Hope you get me.
Still I have one question to you. If I erase the whole internal drive using erasedisk command in terminal, would I be able to boot in from the external usb installation which I have. I wanted to know if some data required for boot menu and all will get erased as well.
Thanks
Naveen

Any way to stop new MacBook Pro hard disk from making loud noise??

I received a brand new MacBook Pro today, and I thought everything was fine. However, when I went to use it in a very quiet room late at night, I noticed an almost unbearable noise coming from the right side of the trackpad. From reading previous discussions, I realize that it is likely the hard disk which is making the noise, and a design flaw makes the noise seem louder.
For other people who have the same problem, is there anything that can be done to make the noise go away?

You can return it for a replacement within 14 days of purchase.

Macbook Pro hard disk has gone

I got the spinning beachball on my MacBook Pro 15" Intel Core2 unibody 2009 OS X 10.6 and then crash.
I zapped PRAM and did Disk Utiliy from Install disk but no hard disk to be seen.
I took out HD and put it in external USB drive, it works perfectly (I can even boot and great, no data loss)
I tried brand new HD inside the Macbook and this can't be seen either.
Help!

Likely something major unless you're lucky and it's a cable (do they have those in MBPs?) If it's out of warranty and you're comfortable poking around inside of computers you could investigate, otherwise take it to somebody who does know computers.

MacBook Pro hard disk noise, froze and wont boot

I was using my MacBook Pro and it froze at the same time I could hear the hard drive cracking. The following are guesses because of the sounds I was hearing: While the hard disk made cracking noises, it would stop spining. Then it started to spin again and another crack would stop the spining.
I held down the power button to shut down and now it wont boot. I can hear the same type of noises I described before.
Thanks for the help

Based on your comments, your HDD is dead. Get a new one, larger and faster if can afford it and swap in your MBP. You will have to reinstall your OS and I hope you have a back up of your data.
Caio.

Macbook Pro Hard disk Makes an annoying sound (buzz) while working but functions properly.

I've got this Macbook Pro 13 inch 2.4 Intel core i5 processor. After about a year the hard disk without any reason started to make an annoying sound (buzzing) while working that sometimes quiets down but when I move the laptop it starts all over again !! Also when I put it down on a side like on my bed while I'm lying on the bed it makes the same sound !! Like when I move the laptop I can hear the buzzing sound changing !! The hard disk functions pretty well though!! What's the problem? I tried Verifying and Reparing the Disk as my father suggested and that helped a bit but after like 10 minutes it's starts again. Any ideas? Have you guys ever seen such a thing before? What should I do?

I have the same issue you're having.
When it first happened (soon after I bought my late 2013 15" MBP), eventually my motherboard and Retina display crashed and needed to be replaced. Now after a couple of months being repaired, I started getting the same clicking sounds opening web browsers or apps, etc. I'm worried its the same thing with the motherboard and or retina display starting to fail again.
Im going to have it checked out however like you said, It's hard to replicate on the spot.
Please LMK if you have any updates on the cause and I'll do the same.
Thanks!

MacBook Pro hard disk upgrade shows question mark folder

I recently bought a 1TB hard disk for my teenaged daughter's MacBook Pro.
I formatted it, used Carbon Copy Cloner to clone the existing drive. I even made sure to create the recovery partition.
I restarted while holding the option key and chose the new drive. It booted fine so I checked in System Preferences to make sure it was selected as the boot device.
I opened the case and swapped the drives. Put it back together and restarted only to see the question mark folder!
I tried booting while holding the option key and now I get the choose a network prompt.
I am desperate and hate the thought of disappointing my daughter. It used to be that I was her hero who could fix anything now I'm the guy who asks too many questions and doesn't put enough money on her debit card. Granted she busts her butt getting awesome grades and I was upgrading her drive so she could continue her video yearbook for her school. So I shouldn't complain but it would be great to be her hero again.
BTW, I am not a newbie to the tech world but I don't do nearly as much in the Apple arena as I do in the PC world. Then again I've been a senior tech in the industry sine before IBM had a PC. In fact, my first real work was on a 6502 processor that used the same machine code as the Rage of the day, the Apple ][. All that to say I usually can find my way around a problem but this one has me stumped.
I appreciate any assistance offered.
Thanks,
Thom

I tried to reboot with the option, command P. And R keys pressed. I heard the ding several times it still showed the question mark! I also tried the shift option and it only displayed the network selection. Also I tried to press C so I could boot from USB and it didn't work either.
If I cannot get this to work I fear my only other choice is to use a FireWire enclosure. This isn't a good option as my daughter does mostly movie work and iMovie has this terrible "feature" that forces all movies to be stored in one place. It sure would be handy if it allowed movie projects to set the storage location individually. I suppose I could simply move all the movies to the drive and try to find a way to point all iMovie projects to the external drive.
Unfortunately, my daughter is one of those Mac users who isn't savvy enough to use anything but the default settings. Heck I've tried to explain to her that she ought to get rid of the big files once she has done her work. That's why her drive is always full.
