I erased my mac os x hard drive and tried installed lion again without knowing that I have to use my apple account, and I have forgotten my details for it.

So I held down option and the power button and erased my hard drive to set it back to factory settings for school and I did not know that I needed my apple details to install lion again, and I dont know the username and password for it because I never really used the apple app. I created another apple account but it says I cannot use that account on it.. Please help, what can I do?

Command R (no option)
From what I learned from testing with a number of people, you do need to invoke IR in certain circumstances.
Command + R will reinstall the currently installed OS version. Apple ID verification is needed.
Command + Option + R will reinstall the originally installed OS version IF that was Lion or ML and the drive is erased first. (This is the option that needs to be used by sellers needing to wipe the drive and reinstall the original OS version before selling the machine; it will also work with a newly installed HD or other problems requiring a fresh install). Apple ID verification is not needed.
IR would appear to be helpful here since the OP is unable to use his Apple ID?

Internal iMac hard drive keeps trying to power down without my consent

How do you stop an internal hard drive from shutting down when you didn't ask it to?
Background:
I use Missing Sync for Palm to sync my Palm handheld with my iMac. My Palm has a SD card slot it in and the sync software came with a program that allows me to mount the
SD card as an external drive on my iMac. From there, I can add podcasts, music or whatever I want directly to the card. I have used this software since March with no problems.
Also, when you put my computer to sleep or shut it down, there is a click and then the internal hard drive shuts down.
Last night, I activated the program to mount the SD card to my iMac and instead of it mounting, the iMac's internal hard drive started trying to shut down.
I have used this program many, many times to mount the SD card to my iMac with absolutely no problem. It was weird this time because I kept hearing that clicking noise. The computer became extremely sluggish. To me, it appeared that the internal hard drive was trying to shut down. After about 4-5 clicks, it succeeded and the computer froze.
Since that time, shortly after you turn the iMac on, you hear that clicking noise trying to power down the hard drive. Sometimes, it just takes a few clicks and the hard drive shuts off. Sometimes the computer will boot all the way up, I can log in and launch a program before it shuts off and the computer freezes. While I can't check the drive with First Aid or Diskwarrior because it shuts off before I can scan it, I assume the data and the drive are ok because I have been able to successfully boot from it and log into my account but shortly after I log in, the hard drive shuts down and the computer is stuck.
Any ideas? Any help would be wonderful!

You are right. It is failing. I took my Mac into the Apple Store and talked with a genius. Although the hard drive would not do what it had at home (typical when you're trying to get something diagnosed) I shut it down so he could hear the noise I do.
Sure enough, he said the noise I heard was the drive read head hitting its start position. When a hard drive shuts down, the drive head moves out of the way since the "hard disk" is actually a thin floppy magnetic disc. The noise I kept hearing was indeed the drive trying to shut down.
Fortunately, I did make a clone of my internal drive to that external drive 6 months ago so I was (eventually) able to copy over all the important files, update the external clone and boot off of it.
Sure enough, tonight, I opened Disk Utility and it said in plain red letters that the drive had reported a hardware failure and should be replaced.
Since my iMac is Summer 2001, the Mac Genius said they no longer carry parts for it so he gave me the name of a local place that would be glad to fix it up. I called them and luck would have it that they were completely out of the internal drives used by my model iMac. So I have to check next week to see if they have received more in yet.
The good news is I can get a slightly larger interal hard drive since I was down to 10GB of a 60GB factory drive. So far, I hear I can go as high as 160GB but the RPM must be lower since my iMac has no fans.
Thanks for your help! As much as I didn't want to believe it, you hit the problem right on.

Where has the hard drive gone after installing lion?, where has the hard drive gone after installing lion?

I'm looking in finder but can no longer see the hard drive. Where has it gone to?

If I understand correctly, you can edit what is shown in the side bar within the "Finder Preferences".
under the "sidebar" tab tick the boxes of the things you want to be shown in the side bar of Finder.
under the "General" tab tick the boxes of the things you want to be shown on the desktop.
Hope this is what you are after and this helps.

Just had to put a new hard drive in my Macbook. How do I "backload" my Ipod tunes into Itunes on the new hard drive I had installed?

I just had to put a new hard drive in my Macbook. How do I "backload" my Ipod tunes back into Itunes on the new hard drive I had installed?

Somebody told me that as soon as I connect the Ipod to the computer, Itunes will will wipe it clean and install what is in the Itunes library (which is nothing) and that I would need some sort of software to accomplish this. Does it matter that the tunes on the Ipod were all uploaded from cd's and not purchased?

Wipe out Internal Mac Book Pro hard drive

I need help on how to wipe out my internal Mac Book Pro hard drive. I used the Mac Office demo and now the demos are no longer usable. How can I wipe out the mac book pro hard drive? Should I contact my Apple Care service center for assistance, since I am paying for that service and they can walk me through the process? I want to clear out to what it was like when I first got the lappy. Help, anyone? Thanks in advance.

Extended Hard Drive Preparation
1. Boot from your OS X Installer Disk. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Installer menu (Utilities menu for Tiger.)
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. Otherwise, click on the Partition tab in the DU main window.
3. Set the number of partitions from the dropdown menu (use 1 partition unless you wish to make more.) Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Partition button and wait until the volume(s) mount on the Desktop.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled, if supported.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process will take 30 minutes to an hour or more depending upon the drive size.
Steps 4-6 are optional but should be used on a drive that has never been formatted before, if the format type is not Mac OS Extended, if the partition scheme has been changed, or if a different operating system (not OS X) has been installed on the drive.
After formatting has completed quit DU and return to the installer. Proceed with the OS X installation. Once OS X has been installed and is running you can then run the installer for the pre-bundled software.

Transfer data from mac to external hard drive

I am new to macs and am a bit lost.
I have a made up external hard drive (internal hard drive in a case) - TOSHIBA MK8025GAS Media. It is connected to the mac via USB.
I have been using it to transfer data from my pc to mac. The mac sees it and i can copy things from the hard drive to mac without problems. What i cannot do is to transfer from the mac onto the hard drive.
I pulled up the mac info of the hard drive and its both writable and ejectable (Has two partitions). In the partitions the info states that the owners aren't enabled, cannot turn owners off and cannot be formatted. Also the S.M.A.R.T. status is not supported. Not usre what all this means!
Can anyone tell me how to set it up to be able to transfer files to the hard drive from the mac and if it is possible to still transfer from windows to the hard drive?
Thank you in advance.

Thank you for the info.
A friend also told me that i could erase the hard drive using the disk utility in ms dos format. I have tried this and then could also partition it afterwards.
At the moment this seems to be working in both Mac and PC.
One thing i have noticed is when i try to transfer disk images (over 4Gb), near the end i get an 'unexpected error occured' (error code 1309).
From the internet:
error -1309 fileBoundsErr: file's EOF offset mark or size is too big
Whatever this means?

Restart your MBP holding the trackpad down and hopefully the disk will be ejected. Then try to return it and get a refund or put it in the trash. There is nothing that software does for your MBP that you cannot do yourself or with free software.
If can get your MBP started, delete all traces of the offending software. Worst case is that you may have to erase the HDD and reload the OS and your user data. I trust that you have a backup (minus MacTuneUp).
Courcoul has given you his opinion in a very succinct manner, and as you might surmise, I agree with him.
Ciao.

Help!!!! Will Time Machine Erase Everything on my portable hard drive?

This is my first time using Time Machine. I purchased a 500 gb portable hard drive (Western Digital) which is mac compatible. When I got it, it I loaded all of my files from my pc onto the hard drive. I have transferred some of the files (mostly pictures and documents) to my MacBook hard drive. When I connected my portable hard drive and opened up Time Machine, I located the Western Digital drive fine but it said it needed to be reformatted and that it will erase all of the files on the hard drive. I think there are some files on it that are necessary to run the hard drive so I'm nervous about deleting them. Can I delete them and still have the hard drive run properly? Should I just transfer all of the remaining files to my laptop and then use the Time Machine program? I want to be able to periodically back up all of my files on the portable hard drive.

TM only works with drives formatted for Mac machines. Your drive does not qualify, since your PC can see it. This is why you are being asked to reformat it.
You can partition it and use part for your FAT32 Windows files and the rest as HFS+ for TM, but, IMO, you would be better with a separate FAT32 drive for your Windows files and have one drive dedicated, not necessarily to just TM, but to HFS+.
My TM drive has a Tiger bootable clone on it in a separate partition, but it's all HFS+

How can I erase deleted items from the hard drive?

How can I erase deleted files from the hard drive? Will my machine run faster?

If you've already deleted the files and emptied the Trash they are already, in effect, erased. At least the disk space they occupied is now available.
To be able to offer help we need more information about which Mac you have, which OS you are running, how much RAM you have installed, how much hard disk space you have available, etc.
Go to the Apple Menu>About this Mac - copy and paste the contents of the report here (deleting the serial number of your machine). Once we have that info, I'm sure someone will have some suggestions.

How many hard drives can i install in my mac pro

How do you transfer music from an external hard drive into iTunes on a mac, but not write the music into the mac's internal hard drive?

I am trying to load an external library with about 700 gigs of music into iTunes on my mac, but of course my mac's inter hard drive is much less than that. Is there a way I can load the music onto iTunes without importing it into my computer? I use this hard drive for DJing so it is plugged in the majority of the time. I have iTunes 12.0.1.26 on a 2011 13" MacBook Pro.

Do you use both the internal and external drives for storing music or just the external drive? If both, hold down the option key while dragging media to iTunes to get it to leave the media where it is and add the track location information to iTunes. A better solution would be to relocate the entire iTunes library to the external drive and run it all from one place. This will also make it easier to make backups of the library as you should since you are using this in a professional capacity and your livelihood depends upon it. We can provide advice on how to do this once we know more about your setup (is there an existing library already, and where?)

HT1751 unable to copy iTunes folder from mac to external hard drive, says hard drive can't be modified

when attempting to copy itunes folder to external hard drive, response is unable to copy file, hard drive can't be modified. What does that mean and how to I use external HD to transfer itunes library to new PC?

The drive is probably formated as NTFS, and your Mac doesn't have an NTFS write driver installed. Why not transfer the folder over your network?

My mac air says hard drive full and 90% is full of 'other' which I cant work out what 'other' is as i Have transferred most to my external hard drive

My mac air says hard drive full and 90% is full of 'other' which I cant work out what 'other' is as i Have transferred most to my external hard drive.
Do you know how I can tell how large each file is taking up and what my 'other' category could be?
thanks

Initial easy steps to gain disk space:
- Delete all files in the Downloads folder.
Empty the Trash.
- Start iPhoto.
Empty its trash.
Restart.
Backup:
Run a Time Machine (or other) backup since you are about to delete and move files and you may need to recover from any inadvertent mistakes or decisions. You will need one external hard drive for your Time Machine (or other) backup and a second if you plan to offload some files. (See suggestions for where to purchase hard drives at the end of this message.)

Methodology to protect your data. Backups vs. Archives. Long-term data protection:
https://discussions.apple.com/docs/DOC-6031
Deleting files:
Then use the free application OmniDiskSweeper http://www.omnigroup.com/more to explore your volume in descending order by size so you can attack the problem from the top down, deleting the largest unwanted files first. Delete with caution and do not delete any system files. Remember to empty the trash after trashing the files.
Additional reference on freeing disk space:
http://pondini.org/OSX/DiskSpace.html
Offloading files:
Consider moving some of the no-often-used large files or directories to an external disk. Use ODS again to find them. This will be at least your second hard drive. Your first one(s) is/are for your Time Machine (or other) backup(s). Do not offload files onto a Time Machine disk.
Format the second drive as Mac OS Extended (journaled). Using OWS to find large files/folders and copy them from the system drive to the external hard drive and delete them from your internal drive.
Then  > System Preferences > Time Machine > Options… > Remove the offload HD name from the exclusions list.
Now both your system disk and your external offload disk will be backed up onto your Time Machine disk.

Basics of File Recovery
Files in Trash
If you simply put files in the Trash you can restore them by opening the Trash (left-click on the Trash icon) and drag the files from the Trash to your Desktop or other desired location. OS X also provides a short-cut to undo the last item moved to the Trash -press COMMAND-Z.
If you empty the Trash the files are gone. If a program does an immediate delete rather than moving files to the Trash, then the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When files are deleted only the directory entries, not the files themselves, is modified. The space occupied by the files has been returned to the system as available for storage, but the files are still on the drive. Writing to the drive will then eventually overwrite the space once occupied by the deleted files in which case the files are lost permanently. Also if you save a file over an existing file of the same name, then the old file is overwritten and cannot be recovered.
General File Recovery
If you stop using the drive it's possible to recover deleted files that have not been overwritten by using recovery software such as Data Rescue II, File Salvage or TechTool Pro. Each of the preceding come on bootable CDs to enable usage without risk of writing more data to the hard drive. Two free alternatives are Disk Drill and TestDisk. Look for them and demos at MacUpdate or CNET Downloads.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.
Also visit The XLab FAQs and read the FAQ on Data Recovery.
