HP ENVY initial RAID setup deleted, accidentally wiped hard drive?

I was trying to see if I could find an option to change my new laptop's SATA controller to AHCI, but I should've checked more thoroughly online before attempting anything new in the BIOS. It seems that these laptops are automatically in AHCI?
My laptop had a 1TB SSHD and a 24GB flash Hard Drive Acceleration Cache configured in RAID 0. With my minimal knowledge of RAID, IDE, and AHCI, I thought that removing the RAID configuration would give me an option to change the hard drive controller to AHCI. Without thinking, I "deleted" the RAID volume, and I think I may have completely wiped my new hard drive and OS, including the recovery partition.
When I startup the laptop, I get the "boot device not found 3f0" error, and f11 does not work to try to go into the recovery mode. The hard drive test still passes both items. I've just now ordered USB recovery media from HP, but I'm not sure if there's anything else I can do?
I don't exactly know how the Hard Drive Acceleration Cache works, but my main question is why would a single SSHD be setup in RAID 0 from the factory, and if there's a good reason, how do I set it up again after reinstalling the OS from the USB media?
After screwing up my OS, I've played around in the BIOS to re-setup the RAID0, but I'm not sure I have it right. I remember the strip size was set to 128kb, but I have no idea what the "Capacity(MB)" used to be or what I should set it to when I create the new RAID?
Any help would be appreciated. Thanks.

Hi, Ryan:
Everything you read was correct about SSD's and TRIM only being supported for drives in AHCI mode until the advent of the Intel Series 7 Chipset.
Now, RAID mode is just as good for that purpose if your desktop or notebook PC has an Intel Series 7 or newer chipset and has the latest version of the Intel RST software.
TRIM was not working on your desktop PC until you changed the BIOS setting to AHCI.
The W8 product key is now encrypted in the BIOS in a further attempt by Micro$oft to combat software piracy, and the illegal use of OEM product keys on other PC's.
In the meantime, while you wait for your recovery disks to arrive, you can download this plain W8 x64 OEM ISO file and use that to reinstall W8 on your PC and you can experiment with configuring it to work properly.
This file will work with the product key in your BIOS.

Use this tool to make the file bootable onto a 4 GB flash drive or DVD.

I accidentally made my hard drive an image of Mac OS X 10.6.3

I accidentally made my hard drive an image of Mac OS X 10.6.3, and I cant erase the hard drive anymore. Please tell me there is a way to be able to erase the image on the hard drive and put it back to the original settings?

Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install Mac OS X 10.6.8 Update Combo v1.1.
You will have to restore your deleted files from a backup. If you don't have a backup, then they are lost.

Will my files i saved using time machine still exist if i delete from my computers hard drive?

I recently had a problem with my computer. I bought an external hard drive and used time machine to back up my 15in mac book pro before sending in for repair.
I have gotten my computer back and needed to delete files from the hard drive on the computer ( close to capacity). Was I safe to do so knowing that everything is saved on my external?
My concern is that if I plug in the external hard drive it will now see those files have been deleted from my computer and delete from the external as well.
-David

Just wanted to add to this conversation - Time Machine will keep copies of your files for some time. It is a backup system, after all. Deleting the files from your main hard drive will not cause Time Machine to go and delete them from your backups.
However, eventually, Time Machine is likely to run out of space on your hard drive, and it then does some cleaning up so it can continue working. A file that is not on your hard drive will not exist on your Time Machine backup forever. Eventually it will be deleted to make room for more recent backups. I can't predict how long this will take, but if you have bought a 1TB or so drive for your Time Machine backups, I would suggest that you might be able to keep some months of backups online - after that, old files that you no longer have on your Macbook Pro will be cleaned away.
So Glenn is spot on - if you want an archive copy of those files, you should make a separate backup - Time Machine does not keep your files forever!
Hope that helps.

ITunes Doesn't Delete Movies From External Hard Drive

I have all of my iTunes media on an external hard drive. However, when I just tried to delete a movie (from within iTunes), it removed the movie from iTunes, but the actual mpeg file is still on my external hard drive. Is there something I'm doing wrong, or am I going to have to manually delete content from external hard drive? Thanks.

When you delete an item from your iTunes library, iTunes will give you the option to delete the file too, but *only for items that are located in your iTunes Media folder.* So, assuming your iTunes Media folder is on your local drive, what you are seeing is the correct behavior.
The best procedure in this case is to right-click the track in iTunes, choose Show in Finder, and delete the file within Finder. Then go back to iTunes and delete the track from the library.

ITunes Match deleted songs from my hard drive. I had to re-rip them. How can I stop this from happening?

iTunes Match deleted songs from my hard drive. How can I prevent this from happening if I try it again?

iTunes Match can in no way be considered a backup service, this is due to the inexact nature of the 'matching process' (see https://discussions.apple.com/docs/DOC-4112, for more detail).
Loss of files from a Disk is certainly possible through media failure. However, the extent of iTunes Match capacity is solely to influence the content of the cloud. Perhaps there was a coincident, or pre-existing, failure of the disk which was simply exposed by the iTunes Match interrogation of the disk content.
There are certainly other services which depending upon your goal may work well. For example, Google Play with gBeats IOS App works very well. My use of Match is to synchronise across several computers and to drive Apple TV and an IOS device - other IOS devices still use sync for specific music and are complimented by gBeats for access to the full library when local mobile signal strength is high.
The strong advice to always start with a secure backup remains but if your primary concern is iTunes Match interfering with physical disk content you can relax - it simply does not have this ability. (Apology to Sherlock, further investigation required).

DELETING FILES PERMAMNENTLY FROM HARD DRIVE AND PASSWORD PROTECTING

DOES ANYONE KNOW HOW TO PERMANENTLY DELETE FILES FROM THE HARD DRIVE? ALSO, WHAT ARE THE STEPS TO ADD A PASSWORD TO A FOLDER?
THANKS!

#1) Please check your caps lock key which seems to be on and many perceive as shouting your questions.
#2) Use secure empty trash when you want secure deleting.
#3) There isn't a folder password feature. There's a utility which will let you hide folders with a password, but that is easily circumvented. Then there's making password protected, encrypted image files. The second is very secure but it isn't a folder, it appears as a new volume on your desktop.

Restoring deleted photos from lightroom hard drive

If my photos were deleted from my lightroom hard drive, what is the best method to re-import or restore my "back up photos" back into my drive and original catalog?

I think it would depend on your catalog back ups and how the photos were deleted and how many.
If you have a back-up of the catalog before the files were deleted and it was your entire photographic catalog which was large is size , then you can do as DJ suggested. It would probably be the fastest way. After the photos are restored to their original location, you may have to go to File>Import from another catalog, and then choose the folder location of your backups and select the most recent.
If you are speaking of just a few photos, or maybe just one folder, you can simply restore the files on your PC or MAC, and re-import using Add.
Hope that helps.

Can't clear deleted events from my hard drive

I guess I'm pretty new at this. I deleted a few events by hitting the delete key but my hard drive is still nearly full. I can't find them now under events or rejected clips or in my movie folder at all. I guess I need to learn how to delete them properly. But how do I now find those (now seemingly hidden) files and delete the properly?

It's not that. My trash can is empty and re-emptying it doesn't help. The files are apparently hidden from my sight so I don't know how to select them and delete. I tried to do a word search for the title, but that also brings nothing. I had 44 gigs free before this new movie event and now I have only 5 gigs free. So it's got to be somewhere.

If the Mac came w/system DVDs, you will need to obtain them prior to selling.
You can get replacement System Install & Restore CD/DVDs from Apple's Customer Support - in the US, (800) 767-2775 - for a nominal S&H fee. You'll need to have the model and/or serial number of your Mac available.
If you're not in the US, you may need to go through the regional Apple Store that serves your location to find the contact number. Here's a list of links to all of those - http://store.apple.com/Catalog/US/Images/intlstoreroutingpage.html Another resource: International Support Phone #s.

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.

RAID 1 setup on Main MacBook Pro Hard Drive Behavior!

Hello...
I have:
-MacBookPro - OS X 10.6.4 - with 1-TB 2.5" Hard Drive.
-A 1-TB 3.5" External USB Drive.
-Master Hard Drive booting and working fine.
-USB Hard Drive is attached and formatted with no problems.
My intention:
-I have the will to use RAID-1 as a solution to mirror the master Hard Drive (the only Hard Drive in any Mac Book Pro!) to the 1-TB USB Hard Drive.
-I read that I can do that using the MacBook Pro Recovery CD. This is with using the RAID tab in the Disk Utility.(No problem so far).
Question/Doubt:
-It is a Laptop Computer, and I take it with me everywhere; normally, I would disconnect the computer from the USB hard drive when I am on the move.
-I would use the computer at work or anywhere else; so, data would be accessed, modified, added, or even deleted!
-Now, if I connect the computer back to the USB Hard Drive, what will happen?
-How would the two RAID-ed hard drives behave?
-Would the Laptop recognize the Laptop Hard Drive as a master/source and the USB Hard Drive as the destination?
-How would the RAID-1 setup treat "rebuilding" for the two drives?
-What would be copied to the Destination drive? all data? changes?
-Lastly, remarks and suggestions are appreciated.
Thank you...
Ahmad

I understand what you want to do. You want a raid 1 so you don't have to keep running backups. That is understood. But, disconnecting one drive will not work. What you should do, is get rid of your superdrive and install an identical 1TB drive in its place, then run both internal drives as a raid 1. Then your problem is solved. You will have a permanent backup of everything you do, as you do it on your laptop no matter where you are.
Another solution you could use is have only your system software and programs on your internal hard drive then use an external raid for all of your important stuff. But you will not be able to access your files on the go unless you copy them to your laptops internal drive, Then any changes to files while you are out will not be protected until you hook back up at home.

How to Restore Data Deleted from Time Capsule Hard Drive

This question is more about the time capsule in general as opposed to a specific time machine issue.
I'm using my time capsule as an external hard drive that I can access wirelessly and I have accidentally deleted a folder. It didn't go into the trash can on the computer I used to delete the file from my TC, it just disappeared. I have data recovery software (Data Rescue III) but it is unable to locate the TC since it is not a plugged in device. I've tried connecting my computer to the TC via wireless, ethernet, and usb but Data Rescue still won't detect the TC.
How can I get the files back? Is there a way to restore files deleted from the TC when it's being used as a hard drive (not as a time machine for backups)?
THANKS!!!

There is only one USB port on the back of the Time Capsule, and AFAICT from reading Apple's documentation, the only uses for that port are to connect an external hard drive or printer. You could try connecting that port to your Mac directly via USB cable, but nothing I can find indicates it would work, and you would be solely responsible if it somehow damaged either device (which may or may not even be a possible side effect).
Unfortunately, if connecting the Mac to the Time Capsule via USB does not work, you're probably out of luck. Unless you are willing to crack open the Time Capsule, remove the hard drive and put it in an external enclosure so you can access it with Data Rescue, your data will remain lost. Note for the future that you absolutely *should not ever* keep original, un-backed-up data on a backup drive. It's poor organization and dangerous to boot.

How do i retrieve deleted data from external hard drive

I accidentally erased all my data from my external hard drive. Data included pictures, documents and movies. They are so important to me! Is there any possiblity for me to retrieve the files?!

So you deleted all the files and then emptied the trash already with them in there? Are they backed up anywhere for you to restore from?
There are 3rd party data recovery programs you can buy to try and restore the data, the success of the program recovering everything is not 100% and the program's success is decreased if you continued to write to the hard drive (by adding content) after the mass purge.
I've used Prosoft Data Rescue 3 with success in the past - http://www.prosofteng.com/products/data_rescue.php
You can find it for as low as $75 on the 'net if you shop around. To put it into perspective, data recovery service will run you (potentially) 7-10x more.

Oh no! I deleted everything on my hard drive! Help!!

So I have a new question.
(My previous post was about a pdf reader which I was successfully able to install on my laptop by splitting it among floppy disks.)
I somehow (?) accidentally deleted everything on my PowerBook's 2400c Hard Drive, except for the system folder in like 3 seconds.
Does anyone know how I could get it back?
My operating system is OS 8.1. Absolutely all of my applications/documents are wiped out, but the computer still works fine. It also only takes floppies, and I can't connect to the internet.
What happened was I was deleting a single file, but then when I emptied the trash, it started counting down and ultimately deleted -800 files. When it asked me if I was sure I wanted to delete the desktop folder etc., I finally realized something was wrong and tried to hit "stop" but by that time it was already too late.
I have made very sure not to write any files onto my hard drive.
Thanks!!
ps. if it is totally hopeless that's good to know too

IF you desktop is missing you can try to rebuild the desktop:
