Photo recovery on Mac operating systems

For many years when attempting photo recovery Mac users were forced to borrow time on a PC so as to scan secure digital and other camera memory cards for deleted files. These files would then need to be converted to a universal format such as a JPEG before they could be installed on to the Mac for viewing. A problem with this system beyond the obvious inconvenience was that it still did not make possible scanning of one’s Mac internal computer hard disk drive for stored and transfer convention and RAW camera files.

With the implementation of Mac OS X photo recovery tools aimed precisely at Mac users were developed. Among these is the Remo Recover Mac program. Downloaded onto and operated directly from the Mac platform this powerful and robust digital photo recovery utility will recognize any and all digital image files on both your Mac Computer and any powerful device such as a camera memory card connected to it.

Repairing an email inbox corrupted by virus attack

One of the most popular ways for a virus or other malware to spread is by means of e-mail. However, because most virus attacks are sent via a PC and not a server application, viruses must find a way to attach themselves to your e-mail sending system. When using Microsoft Outlook this is done by corrupting the Outlook inbox and the database for it which is known as the PST file.

Corrupted PST repair can be accomplished in many ways but the basic technique is to use a mirror file. A mirror file is simply a clean non-corrupted representation of your Microsoft Outlook PST database. One can either extract the core information from their corrupted Outlook file system and install it into the clean new PST file or one can use the newer file as a basis and rewrite the header instructions on your PST file. These are the two PST repair methods most in use.

File recovery on reformatted hard drives

Eventually if you use a computer long enough you will have to deal with a hard drive crash. The basic solution for repair of a hard disk drive that has suffered a logic crash to is to reload your Windows operating system. However doing this formats your hard drive and formatting your hard drive deletes all of the files stored on it. This leaves you two options. The first is to use a data recovery program connected to this hard drive by means of a second computer and direct that computer’s operating system to copy from your crashed hard drive all of the files.

The second option is to go ahead and reload your operating system knowing that it will reformat that drive. Data recovery after reformat of hard drives is very possible. To recover data from formatted drive partitions you will need a file recovery program that treats those formatted drive areas as if it were deleted files. Most of the better data recovery utilities perform in this manner.

The possibility of web-based email recovery

Very often I am asked how one recovers accidentally deleted emails that were originally placed on a web based e-mail service. If you rely upon the free email services such as AOL or Gmail and accidentally delete messages, those messages will be temporarily stored in a trash bin. As long as the time allowed for recovery has not expired you can simply enter that trash bin and as you would with your Windows recycle bin restore any recently deleted messages.

Unfortunately when I am asked this people are trying to recover a message they deleted months beforehand. This is an impossibility and for this reason anyone who sends and receives a great quantity of emails should use a localized e-mail client such as Microsoft Outlook or Outlook Express. There are programs available that will help you to recover accidentally deleted emails on any PC based e-mail client. In fact using these programs one can recover deleted emails even if the entire folder has been discarded.

Recovery of partition data after formatting

How is one to restore their computer to operation if the operating system files have become corrupted and the computer’s internal hard disk drive will not allow the PC to boot? There are two options available. The first, which is the most preferable, is to connect that hard drive up to a second PC as a slave unit and use the operating system on that PC to access all stored files. These files are then copied to a safe external location. However if one also needs to recover from that hard drive damaged or deleted files the process of accessing the data on the crashed hard drive must be undertaken using a powerful data recovery program. These programs are designed for the task of reconstructing deleted files.

The second option which is somewhat unique is to reload your Windows operating system on to your PC prior to file recovery. This process will reformat your computer’s internal hard drive and subsequently delete all data. You will then need to recover formatted data using a similar powerful third party data recovery utility. This should be noted that one attempts to recover formatted partition information in this manner the percentage of recoverable files is far less than when attempting recovery prior to reloading the operating system.

Clearing up the confusion of recycle bin recovery types

Recycle bin recovery is often confused with the process required to reinstate the Windows recycle bin icon when it has been accidentally deleted from your computer’s desktop. To do this all one need do is right click the mouse on the desktop and follow a series of defaults. Most recycle bin recovery refers to the need to recover files from emptied recycle bin storage. This is the number one cause of accidental file deletion when working with a computer.

Very often we think we will no longer need a file or application and drag it over to our Windows recycle bin. So long as we do not empty the bin we always have the ability to open it and restore any file it contains. But once the bin has been emptied those files are permanently deleted. Fortunately there are programs for recycle bin recovery designed to help anyone regardless of their level of computer expertise to locate files that have been emptied from the recycle bin prematurely.

Photo recovery for complex proprietary digital image files

Digital photo recovery presents a unique situation different than most simple file recovery problems. The reasons for this are two-fold. First, recovery of lost image files usually takes place in two different locations, these are the hard drive of your computer and whatever storage media being used on your digital camera. Second, digital photo files are stored in both conventional image file types such as jpegs and proprietary file types as created by the camera manufacturer.

For example Canon Digital SLRs store their files onto the attached high density secure digital card in the unique Canon format. There are two of these, .crw and .cr2. Your digital photo rescue tool must be expressly designed for Canon file recovery. It must be able to recognize these proprietary file types and reconstruct them. Most general purpose data recovery tools are not designed to recognize unique file types. While they may be able to find common image files, rarely are these programs capable of Canon file recovery.

Recovering files lost in a damaged Outlook inbox

Very often people who use the Microsoft Outlook e-mail client wake up to discover that either emails are missing from their folders or that their Microsoft Outlook inbox is no longer allowing entry of mail. The most common reason for this problem is that the Microsoft Outlook database known as a PST file has become damaged or corrupted. Because this storage location, the PST file, is actually a type of database most corruption to it occurs in the form of damage to the file creation tables.

In terms of a simple explanation consider these tables as headers to the stored data. In order to repair Outlook inbox damage and return your application to functionality you’ll need a program to recover Outlook PST information. Microsoft Outlook repair software accomplishes this by scanning your Outlook PST file and comparing it to a known valid application. The program then replaces the corrupted components restoring your Outlook client to operation.

Using the proper tool to recover your Mac information

Would you attempt to drive a nail by using a screwdriver? This is a valid comparison of what people attempt to do when they try to recover Mac files using a program designed for Windows. Many companies that produce Windows data recovery software try to sell the public on the idea that their programs will also suffice to recover Mac data. This is true on one very small level.

Theoretically if one were to download a Mac recovery program that uses Windows as a platform onto a Windows PC and connect that PC to a Mac it might be able to recognize a few files and recover them. But actual Mac recovery is a far more complicated process. The difficulties involved in recovery of Mac files are much more complicated than can be explained in a simple article. The main point to understand is that unless a software utility specifically loads on to a Mac computer and from that Mac can either connect to your hard drive or access connected devices is not a true Mac recovery program.

Restore files lost from SD memory cards

The base SD card was developed in 1999 and was limited in size to 64 MB. That size would hardly be of value today. SD cards quickly grew in capacity to 256 MB and 512 MB. At the later stage they began to find great favor in use with digital photography. As cameras upped their pixel count SD cards grew to match so that a standard of around 100 digital photographs stored was maintained.

The standard today for SD cards has grown to 4GB. Beyond that number the cards are actually referred to as SDHCs. When attempting to restore lost data from SD card media one merely treats that device as one would any external digital media that is connected to their PC or Mac. To undelete pictures from SD card media simply connect the card to your PC by means of a built in slot or a card reader. You will then need to download a Remo Software photo recovery program and direct that program to read the drive containing the SD card.
