Is It Possible to Retrieve Deleted Text Messages From an iPhone?

Everyone loves to text, and these days it is easier than ever with smartphones that are touch screen, have auto correct (which, frankly, can be annoying at times), and even some third-party apps that allow you to text for free. As with anything, popularity and frequent use comes with a price - problems.

How many times have you deleted a text message that is full of information that you need back? Do you think that text message is gone forever? In some cases, that may hold true, but there is a good chance that you can get some or all of the information back.

Take an Apple iPhone, for example. Much like a computer, when information is deleted it is not truly erased. When you delete a text message from an iPhone, it is actually still there. However, it is now being held in the unallocated portion of the physical memory. The bad news is that anything that is in the unallocated portion of the memory is subject to being overwritten. Thus, consider the biggest factors that affect the retrieval of iPhone text messages are available free memory and usage.

Is It Possible to Retrieve Deleted Text Messages From an iPhone?

For example, if you have a 16GB iPhone and it has 15.8GB of music, photos, text messages, and apps on it, chances are unallocated memory is going to be overwritten quickly. Along the same lines, if the iPhone user is texting constantly (like my teenager who sends and receives in excess of five thousand text messages per month), the risk of the deleted text messages being overwritten increases. Another thing to keep in mind is that there is no rhyme or reason as to the way an iPhone writes data to the physical memory. It doesn't care if the data is old or new, it just writes it to whatever portion of the unallocated memory is easiest to write to at the time. Thus, when recovering deleted information, you may get back all of the message, but you may also get back only part of it.

Some say that your cell provider can give you access to all of your incoming and outgoing text messages. Although it is true that some cell carriers maintain the content of all incoming and outgoing text messages, I have found it to be the case that they will not just give them to you. Most need a court order as the only reason they retain this information is for law enforcement authorities investigation purposes.

Search the internet. There is a plethora of knowledge out there by doing a simple Google search. There are forums dedicated to the subject, and many "techies" roam these forums and post great information. Some call for your iPhone to be "jailbroken", which I don't recommend, but if your iPhone is jailbroken, you may just find the information you need.

If you don't want to do or feel comfortable doing the forensic work on your iPhone yourself, there is recovery software on the market. One of the most important things you can do before purchasing any type of recovery software is to know your iOS version. Make sure that the software you get is compatible with your iOS version, and it is also best to make sure that the software comes with free updates. This is because Apple releases iOS versions fairly regularly, and if your recovery software doesn't come with updates, it will soon be outdated. You never know when you will need to use it again!

Beware of SIM card recovery software when dealing with iPhone! AT&T iPhones uses the SIM card for GSM (cellular network) service only. They do not save text messages to the SIM card.

Accidents can happen to anyone. If you have inadvertently deleted text messages that you need and are looking for information on how to retrieve iPhone deleted text messages, there are plenty of options that may help you get them back.

How Data Is Stored On A Hard Drive

When a file is saved on a computer, the data is stored on the hard disk platter's magnetic coating. This magnetic coating on the platters is the 'glue' that keeps your data. Any damage to that magnetic coating means that there is data loss as each piece of missing coating contains data. So a platter missing a little bit of that coating has a better chance of a successful data recovery as opposed to a platter that has had massive amounts of that magnetic coating removed or destroyed.

Hard Drive Failure Parts

Typical hard disk components that fail include:

How Data Is Stored On A Hard Drive

Platters Hard disk platters, or spindle, is rotated by an electric motor. The speed of this rotation is measured in rotations per minute (RPM) and the higher the performance of the hard drive...the higher the RPM is which increases the reading and writing of data to the platters. Any surface contact to the platters can cause serious damage to the magnetic strip the contains the data. This includes dust, finger prints, water, and most important of all, the heads of the hard drive. Platter damage is the most serious type of damage to cause hard drive failure.

Heads (Head Crash) When the hard disk is not actively in use, the heads are parked until the hard drive needs to read or write data again. It is when this head moves outside the super thin cushion of air between platters that causes the head to crash and touches the hard disk platter.

Firmware Firmware is the program instructions located on the chips on the Printed Circuit Board (PCB). Each firmware revision is specific to its hard drive type and each hard drive can go through dozens of firmware revisions to increase that particular manufacturer's disk drive's performance. The older the hard drive, the more difficult it could be to find a working firmware for that specific hard disk model.

Printed Circuit Board (PCB) The PCB of the hard drive is the electronics of the hard disk that manages and operates the hard drive. If a PCB becomes damaged it is often replaced with an identical PCB with the same firmware on the original hard drive. Typically PCB damage is from water or fire, but there are other reasons why a PCB would fail. And many times a failed PCB affect other aspects like firmware or heads.

Types of Hard Drive Failure

Generally speaking, when a disk drive fails it is due to one of the following causes:

Media Failure Otherwise known as a head crash (as described above), the heads of the hard drive have physically touched and damaged the magnetic coating on the platters.

Mechanical Failure Generally speaking, any electronic failure to the hard drive falls in this category. Fire, water, electrical damage to the hard disk would require 'parts' replacement.

PCB Failure As described above, PCB failure falls in the mechanical failure type and typically can be 'swapped out' for an identical PCB for that specific hard drive type. Along with the correct firmware for that disk drive, a PCB replacement can be a difficult type of hard drive repair if the hard drive is an older model.

Logical Drive Failure This type of hard drive failure is usually the least damaging to the data. This type of error usually means that the operating system of the computer (or utilities) can see the drive, has marked it as unallocated space, but because the computer's MFT is corrupted or damaged, can't read the data. Hard drive failure of this type is not that destructive and the chances of a complete successful data recovery are high.

Types of Non-Mechanical Hard Drive Failure

Other causes for data loss and why data recovery would be required could include the following:

Natural Disasters Extreme weather conditions that are out of our control can make a bad day even worse. Whether the computer was submerged in water due to a flood, scorched by fire or in the proximity of a lightning strike, there is still a chance to recover data from the hard drive.

The Human Factor Accidentally deleting files, formatting the wrong hard drive, and attempting to upgrade you operating system only to have it fail are common issues that come up. Also, as careful as most people are with their laptops, a small drop from the couch to the floor or down a flight of stairs, is the type of forceful jarring to the disk drive that could cause serious damage to the hard drive platters.

Viruses E-mail typically are the way most viruses are spread from computer to computer. Also, visiting questionable websites that have scripts, malware or spyware waiting to comprise your system and put your data at risk. It is recommended to run the most recent anti-virus software to protect your data from this sort of data loss and to reduce the need to require data recovery service.

So how do you protect yourself from losing your data? Back it up! However, should you still require data recovery services, be sure to use a company that specializes in hard drive data recovery.

How Do You Reformat a USB Flash Drive?

USB flash drives have become really handy in storing different files of various sizes including, backups, personal documents, music, pictures, portable applications and more. Flash drives turned out to be so convenient that people start pouring in files of any kind without sorting them. Because of these habits, flash drives end up getting real messy quickly and it becomes difficult to figure out how to clear up disk space to accommodate more files.

Deleting unnecessary files is a good solution, but can be tough to do when files aren't properly organized. If you want to clear up disk space the fastest way possible, the best problem solver to this is by formatting your USB flash drive directly. The advantages of doing this is that your flash drive is wiped completely clean, removing all files regardless of their attributes (including hidden files). Here are the basic steps in reformatting your USB flash drive:

Backup your data

How Do You Reformat a USB Flash Drive?

Formatting your USB flash disk doesn't leave any files behind so make sure you copy your most important files to a temporary location. If you plan to put these files back after formatting, organize the folder structure so you can better manage your disk next time you have disk space issues.

Reformatting your drive in Windows

Open up your "My Computer" (or "Computer" in Vista) from the Start Menu and look for the drive that has a "Removable Disk" icon. This is usually assigned to the last drive letter and may show multiple drives if multiple devices are plugged in. Right-click on the device you wish to format and select "Format".

A dialog should open up showing several options; leave all the options alone unless you want to change the volume label. You can leave the "Quick Format" option unchecked to make sure everything is deleted without errors and doesn't take too much time to begin with. Click the "Start" button on the dialog and wait for the device to fully format. You should end up with a clean flash disk that is ready to accept more files.

Reformatting your drive in Mac OS X

Mac OS X users can format a flash disk by loading the "Disk Utility" program located in the Utilities folder that is inside the Applications folder. Your flash drive should be in the list showing a white drive icon. Click that icon and select the "Erase" tab on the main window. Select the "MS-DOS (FAT)" option if you wish to make the drive compatible with Windows operating systems and give it a volume name. The format will begin when you click the "Erase" button below.

Formatting is a rather easy task so next time you feel the need of freeing up disk space or removing a nasty virus, you can format the device without nagging your techie friends and relatives in doing it for you. Just keep in mind that it is close to impossible to recover the data that you erased while formatting unless you have decent recovery tools so always double check your drive before you begin formatting.

How to Fix Windows Server 2008 Boot Loader

If the boot loader to your Windows Server 2008 machine gets corrupted or deleted for whatever reason, it really is a painstaking process to get it fixed. The boot loader to my machine got deleted somehow while I was resizing partitions. After scouring the web, I could not find anything on rebuilding the boot loader for Windows Server 2008. All I could find were instructions to restore a Windows Vista boot loader but luckily, the process for Server 2008 is similar.

Due to the lack of recovery tools on the Server 2008 installation CD, the boot loader must be rebuilt manually.

For this guide, I'm going to assume your installation has a drive letter of C:.

How to Fix Windows Server 2008 Boot Loader

Insert the Server 2008 installation CD into your DVD-ROM. Restart your computer and boot from the CD.

Choose to repair your computer, then open the command prompt.

At the command prompt, use the following commands:

c:

cd boot

bootsect /nt60 c: /force /mbr

bootrec /rebuildbcd

After using the "bootrec /rebuldbcd" command, you will be prompted to accept a Windows installation. Accept the installation, then wait for the process to finish. Once it's done, reboot your comptuer and you should have a boot loader ready to go.

If you do not have a "boot" folder in the system C: drive, then copy the "boot" folder form the Windows installation CD to the C: drive. Use the following command which assumes E: is your DVD-ROM

mkdir c:boot

copy e:boot* c:boot

Afterwards, just use the boot restore commands to rebuild the bootloader.

SD Card Recovery - How to Undelete SD Card Files Easily

An SD card is a secure device or disk, similar to the SIM card in a cell phone. It looks very similar to a SIM card, but it is much smaller. The SD card in a digital camera or iPod or other multimedia device allows you to take photos, video, download music and ringtones, and other media matters and files to your computer. You can save a certain amount of data on your SD card, and when it is full, you can download the data onto your PC, to publish to the web or just save those family pictures to your hard drive or to a writeable CD.

On any media device with an SD card(memory card), there is an option to preview all the files and decide which to keep, and which to delete. Sometimes files downloaded from the Internet can be corrupted or contain viruses, so you get file that doesn't work properly. It won't play that hot new song you downloaded, or it won't show all the video you took of your cousin's last drunken escapade into the neighbor's pond. This is extremely frustrating. You paid for that song. You are dying to blackmail your cousin with that video. (You had to stay sober all night to catch him skinny-dipping in the neighbor's pond!) When you accidentally delete a file you wanted to save, or the file was corrupted for some reason, what do you do? How are you supposed to fix the problem and undelete SD Card files?

Relax, don't panic. There is a way to undelete everything on your SD card. You can download Memory card (SD Card) recovery software for this in a few places on the web, but your best bet is to pay for software specifically meant for the platform or operating system on your PC. The recovery software will open a Wizard-style interface when you open the program, and allow you to preview all the files you wanted to keep, restore all the ones you want to restore. You can even restore files and uncorrupted files already on the hard drive of your PC. Undelete SD Card files so your music will play, recovering the blackmail video of your cousin in the neighbor's pond, uncorrupting files you already have on your hard drive, and fixing any of your other storage cards and memory cards, including XD cards, USB drives, etc.

SD Card Recovery - How to Undelete SD Card Files Easily

You can recover any lost files you want, undelete any memory card files you want and save them to your computer or to a writable CD. Recovered files work as well as if they had never been accidentally deleted or corrupted in any way, even those that were corrupted by a virus. Don't despair; you can get all your media files and document files back onto your computer or disk for easy access with the right software!
