PC Data Rescue

Accountancy software company Intuit has created a waiting list for users affected by a flawed update to its QuickBooks Pro application.

The update erased QuickBooks data from the hard drives of many users last weekend, Intuit acknowledged. It affected the Mac OS X QuickBooks software, versions 2006 and 2007.

Users reported that applying the automatic updater sometimes deleted their Desktop folders, which could result in the loss of gigabytes of data. The data loss occurred after the updater displayed various fallacious error messages, such as warnings about there being insufficient disk space or a lack of network connection, according to several posts Dec. 15 and 16 on Intuit and Apple support forums.

“A percentage of user files had been shoved into the Trash, while others were marked as deleted when they shouldn’t have been,” said Drew Janssen, owner of DriveRescue, a Baltimore-area data recovery service. “It’s worse than we first thought.

The phone’s been ringing pretty steadily since Monday morning, from all over the country. Something in the updater process in the QuickBooks update was deleting the Desktop and some other files.”

The main reason for this problem seems to be the working process of the OS X which does not place the deleted files in the Trash. This might have caused some users to put the files back in their respective folders. So, these files are invisible to the user and the computer is signaled that these files are available for overwriting.

The company suggests that the users who are affected by this bug should stop all the work. Also, the QuickBooks updater requires users to type in the administrative password for the computer.

Although this is one of the strengths of QuickBooks in protecting the users against viruses, this acted as a drawback as the administrative password allowed the updater to do whatever it wanted to do.

Hard disk is a permanent storage device for storing electronic data on a magnetic surface. Hard disk was invented by Reynold Johnson which was capable of storing five million characters. Now-a-days hard disk capacity has increased tremendously with storage capacity of 1 Terabytes. As storage capacity has increased so chances of losing such a huge amount of data form the hard disk.

Hard disk failure can when there is a break down of the hard drive (termed as physical failure of the hard disk) and data stored on the disk cannot be accessed. There are various kind of failure which our hard disk suffer the most common is Head Crash.

Head of the drive is an important component which is used to read and write the information from the hard disk. Head just moves over platter only at a distance of micrometer. Any sort of collision results in severe data loss. If we try to do the recovery by our own can result in further damage of the data.

There are numerous factors which causes hard disk failure. The most common are power surges, voltage fluctuations, electronic malfunction, physical shock, wear and tear, corrosion, exposure to high magnetic waves, sharp impact, high temperature exposure etc

Hard disk failure is increasing higher, as to increase the speed or read/write operation we are rotating the hard drive with great speed. If any thing goes wrong with the normal operation of hard disk causes severe damage.

There are several techniques used by data recovery experts to recover the data from the failed hard disk. It is done by moving the hard disk to working system. Hard disk is open to replace the parts like head of the drive, arm and chips and sometimes change of platter is also done to make it working such that data recovery can be done on failed hard disk.

Apart from the physical failure of the drive, if our hard disk has suffered a logical crash then in this case data recovery software is helpful. Logical crash can be termed as inability to access the data from hard drive or data lost due to accidental format, viruses or software malfunction or even sabotage.

In case of recovery of data from severely damaged hard disk you should consult data Recovery Company for saving your important data which is trapped inside the failed hard disk.

Data recovery is the process of salvaging data from damaged, failed, corrupted or inaccessible primary storage media when it cannot be accessed normally. Often the data are being salvaged from storage media formats such as hard disk drive, storage tapes, CDs, DVDs, RAID, and other electronics.

This can be due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system. Although there is some confusion as to the term, data recovery can also be the process of retrieving and securing deleted information from a storage media for forensic purposes or spying.

A wide variety of failures can cause physical damage to storage media. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer any of several mechanical failures, such as head crashes and failed motors; tapes can simply break.

Physical damage always causes at least some data loss, and in many cases the logical structures of the file system are damaged as well. This causes logical damage that must be dealt with before any files can be salvaged from the failed media.

Most physical damage cannot be repaired by end users. For example, opening a hard disk in a normal environment can allow dust to settle on the surface, causing further damage to the platters and complicating the recovery process.

Furthermore, end users generally do not have the hardware or technical expertise required to make these repairs; therefore, costly data recovery companies are consulted to salvage the data. These firms often use Class 100 cleanroom facilities to protect the media while repairs are being made.

Hi There,

I’m Richard and the webmaster/developer of PC Data Rescue. Me and my fellow staff hope to give you any information you are after on any data/file rescue and recovery. As we all know it can be a nightmare when you lose important data and cannot get it back.

We shall be writing interesting articles each week, reviewing the best products for data recovery and writing helpful ideas in this blog.

So check back regularly and you will find all the info you need on data recovery.

Thanks,
