HP Protecttools - Disk Encryption - How do I recover a hardrive that no longer boots
I have an HP Laptop that has the HP Protecttools Disk encryption enabled, but will not boot. I need to pull information off of the drive for the employee who owns the laptop and I am unable to becasue of the encryption. I know you can use the key that is generated during the encryption process to unencrypt the drive at the first login screen, however because the drive is not booting I do not get that screen. Is there any utility I can run from a CD/DVD to unencrypt the drive from a command line using the encryption key?
Hello Charon. I understand you need to decrypt a drive for a computer that cannot boot.
What problem is causing the drive to be unable to boot?
Which notebook are you working with? Please use this document to locate the product number and use that to identify the notebook.
Since HP Protect Tool is generally used in an Enterprise environment you may also want to post your question to HP's Business Boards. Here is a direct link.
I hope you have a great day!

How do I recover a directory that I accidentally emptied in the trash?
How do I recover a directory that I accidentally emptied in the trash?
Restore it from your backups. If you don't have backups now you have a really good reason to start keeping a backup. Visit The XLab FAQs and read the FAQ on backup and restore. You may also find my FAQ on maintenance helpful.
Basics of File Recovery
If you empty the Trash the files are gone. Recovery is possible but you must not allow any additional writes to the hard drive - shut it down. When you delete files you erase only the directory entries, not the files themselves. However, the space occupied by the files has been returned to the system as available for storage. 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.
If you stop using the drive it's possible to recover deleted files that have not been overwritten with 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.
The longer the hard drive remains in use and data are written to it, the greater the risk your deleted files will be overwritten.

Kappy's Personal Suggestions for OS X Maintenance
For disk repairs use Disk Utility. For situations DU cannot handle the best third-party utilities are: Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.0 is now Intel Mac compatible. TechTool Pro provides additional repair options including file repair and recovery, system diagnostics, and disk defragmentation. TechTool Pro 4.5.2 is Intel Mac compatible; Drive Genius is similar to TechTool Pro in terms of the various repair services provided. The current version, 1.5.1, is Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep.
OS X automatically defrags files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems.
I would also recommend downloading the shareware utility TinkerTool System that you can use for periodic maintenance such as removing old logfiles and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the commandline.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand. I also recommend booting into safe mode before doing system software updates.
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.

On CS5, how can I recover jpeg images that were Batch Renamed prior to removal from my flashcard?
On CS5, how can you recover JPEG images that were accidentally Batch Renamed prior to removal from a flash card? Is it a total lose or can they be saved somehow?
If they were renamed on the flash card that is a poor practice. If renamed in Bridge the old names can be recovered it you have checked "preserve original name in XMP". If not you are out of luck. But you still have the images correct?

How do I recover a folder that was accidently put in trash and deleted?
If you don't have Time Machine enabled on your Mac you'll need to use a file recovery applicaiton like SubrosaSoft FileSalvage. FileSalvage had a demo mode to let you know what it can find and recover before you have to purchase it. However, it won't be able to recover the folder, only the files in the folder.
Other possible file recovery applications can be found at MacUpdate.com by searching there for "file recovery".

How can I recovered a form that I delete by mistake?
I nee someone help, How can I recovered a form that I create and later on I deleted by mistake? Thank you in advance for your prompt answer
Hi;
I am sorry to say that there isn't any method to recover a deleted form. There is a confirmation dialog saying that this is a permanent deletion to ensure that is what you want to do, once you've confirmed the form is really deleted and not recoverable.
Thanks,

How can I recover a iMessage that was deleted and if not is there a way apple can send me email of all my iMessages in past month
Hi Toniann,
If you have a recent iCloud backup that was done when that message was on the devcie, you can restore from that backup.
No, Apple does not keep your messages, no do they have access to them. That would be a serious invasion of privacy, don't you think?

I have a PowerMac G4 running ProTools that no longer boots up. All I get is a file folder on the screen with a flashing question mark in it. Ran the Utility disk and all systems passed. Any ideas?
You need to use the computer's install disks to repair the hard drive or install a new OS.

I can upload photos and smaller size videos but when a video is 24 minutes long for instance, it doesn't upload at all from my iPhone to the PC. How do I upload these videos that are longer in length?
Are you using any software to import videos? Did you tried Picasa or you just open your iPhone from My Computer?

I have tried all sugestions for how to charge my ipad 2 that no longer charges, and nothing seems to work, can anyone offer any new advise?
While both the iPhone and the iPad use an Apple dock cable for charging, the iPad wants a 1100 mA charger, and the iPhone charger's a 500 mA charger. USB ports on newer Apple computers can switch into 1100 mA mode, but your average computer is going to put out no more than 500 mA and, possibly, quite less (for example, an un-powered USB hub will only put out 100 mA or so, and an iPad won't charge off that). The iPad will say "not charging" if it is trickle-charging (receiving less than 1000 mA of power).
If the problem persists when using the 1100 mA iPad charger, you need to take it to an Apple store and have it serviced or replaced. Bring the iPad charger that you received with the iPad as it may be that the charger is defective and not putting out 1100 mA.
If the problem is that it charges slow because it's being connected to iPhone chargers or PCs or older Macs, then it's not a problem with the iPad. It's charging, it just takes a long time because you are using an under-powered charger. -

This morning I ave unknowingly synced my iPhone to my wife's iPhone's data in iTunes. Now all HER information is on my is on my phone and all of my information has been overwritten. How do I recover my data and overwrite her data. My latest backup to iCloud was yesterday. I have not backed up my phone today and have turned off the auto back up feature, hoping I can still retreive yesterday's data. Can anyone help?
Welcome to the Apple community.
You will need to restore your phone and when prompted use the backup that you made yesterday.
Before you do so, you may wish to change your wife's iCloud login details, otherwise you may find that you then overwrite her data. She should have her own iCloud account to avoid this. -
