A STOP error occurs when your hard drive suffers fatal errors such as hardware defects, incompatible drivers, unsupported software or services, missing or damaged system files etc. They bring operating system to a halt and hence place your data at risk. In such situations, your recent data backup can help restoring the lost files, unless it is not invalid or incomplete. But, if you find any issues with it, Hard Drive Recovery solutions can extract the lost data.

Consider a situation, you start your computer and receive one of the following error messages:

“STOP 0x0000007A”

Or

“KERNEL_DATA_INPAGE_ERROR”

It generally occurs in Windows 2000 based systems. The error message describes four parameters: lock type held (1, 2, 3 or PTE (Page Table Entry), Input/Output status code, current process and virtual address that is unreadable into memory.

Cause

STOP 0x7A error occurs when system requests for a page of kernel data from paging file on hard disk, but fails to read into memory. It can happen due to the following reasons:

Bad sector in paging file

Virus infected hard drive

Hard disk controller issues

Failing RAM

Hardware defect

Solution

To solve the above STOP error, you need to follow these methods:

If I/O status code is 0xC000009C or 0xC000016A, then it indicates bad sectors. Try restarting the hard disk. Doing so will run the Autocheck that can identify bad sectors or alternatively, you can run chkdsk. If bad sectors are logical, reformatting the hard disk will remove them. You can restore lost data from an updated backup. If such backup is not available or invalid, you need to usehard drive recovery software .

Scan your hard disk using an updated and powerful antivirus application, if virus infection is the issue.

If I/O status code is C0000185, you should check disk cables

Consult Hard Drive Recovery services, if hard disk cotroller is causing the problem

You need to run hardware diagnostics to determine RAM failure issues

Hardware diagnostics also identify other hardware concerns

Hard Drive Recovery Software are the special applications that use advanced scanning algorithms to recover data from logically crashed drives. However, disk recovery service is manual assistance provided by data recovery solution providers to extract lost information from physically crashed drives.

Redundancy, or the "R" of RAID has made many IT Administrators assume that RAID data recovery is just not a necessary service. And why not? After all, over the past 20 years, RAID storage platforms have been the preferred selection of corporate environments, rightly seen to be the best the data storage industry has to offer. Ultra-important applications such as high-end database servers including SQL and Oracle and communication tools such as Exchange have all made use of the platform, which provide high speed access to data with a redundancy factor that makes backing up almost seem unnecessary.

The true danger of the RAID platform lies in its illusion of robustness, however. Thus far, it is definitely the best, and most configurable solution the data storage industry has to offer. Meanwhile, look at the essential building blocks of the RAID server and what do you see? Effectively, a RAID platform is simply a clutch of hard drives linked to each other - with each hard drive merely a mechanical device, different although at its core still the same kind of structure as a hard disk from 20 years ago. As of this writing, there is no serious non-mechanical hard drive available (solid state drives make the attempt, of course, but remain very susceptible to wear, trading one form of engineering fault for another), which means - surprise, surprise - RAID servers are destined to fail.

So what then is a prepared administrator to do? Planning is always the best idea, obviously, and is not as difficult as it may seem. Consider these ideas when planning for RAID array breakdown:

Build An Inventory - If you are in control of your organization's IT assets, or have responsibility over some of them, ensure you understand exactly what lies within your duties. This means all assets, from simple user PCs to major mainframe systems. Don't get caught by surprise when RAID or hard drive failure rears its ugly head.

Gathering The Details On Your Assets - Once you've made a list of what Information Technology solutions you're responsible for, it is your duty to create a knowledgebase that will be there for you in the event of disaster. To begin, analyze your list of systems, and prioritize the crucial ones, such as machines that use mission-critical applications such as Exchange servers or Oracle databases. Set about gathering all critical manuals, manufacturer support site details (including that for RAID controller cards and specialized components), and high-quality technology forums. Better to find and catalog this knowledgebase now, as opposed to when you're in a wild panic.

Who You Gonna Call? - So an all-out RAID failure has just occurred. I guess you have a fully qualified 24 hour RAID repair vendor already in your Rolodex (do people still use those?), so you can easily give them a call and begin the process of getting the hardware to them. Not the case? It should be. In fact, why not take the time out right now to build yourself a shortlist. Investigate not only data recovery companies, but those that specialize in RAID repair, or better yet, one day turnaround RAID recovery. Call the technicians today, and simulate what a disaster might be like. How does the shop handle it?

When it comes to the overall safety of your systems (and your job), there's no such thing as "being too proactive". Being cool under pressure is paramount in a case where RAID data recovery is your only choice, and will ensure that your emergency is more a bump in the road than a critical catastrophe.

For all the background users, whether from the technician scene or general, hard drives are always the counterparts for the data storage. No hard drive means your system is not more than a metal box containing wires and circuits. There would be no E-mailing system, operating system use or World Wide Web without computers.

Here the importance and usage of hard drives tell how dumb the technical world would appear without the hard drives. Therefore the hard drive crash is one of the biggest problems for all those dealing with it. The reason for crash can count from the harsh hardware problem to the logical errors due to corrupt system files and threatening viruses.

The owner of the system is not always to blame. The hard drive consists of many magnetic disks, which have the ability to spin at the rapid speed, each surface having the hovered head to access and collect the data. If the motor sits back, saying no to spin the shaft connected to platters or the head fails to function, the hard drive will crash. This would need manual hard drive recovery procedures to apply.

The other way, where data loss can halt your way is the file removal from the hard drive. The system files may get corrupted, the operating system may get damaged, the user may delete any file, formatting of the hard drive may be faced; spyware or adware may delete the data and so many. These cases require the according logical hard drive recovery through software.

Well, the little alertness would let you know the difference between the mechanical and software problems i.e. which has affected your hard drive. This is necessary as the hard disk recovery procedures are typically based on these examinations only.

The system is not booting up at all, try attaching it to some other system. If it functions there, means you have no argument with the hardware. This can be easily cured through the hard drive recovery software as this could be the system software glitch or virus of some sort. However, attaching it to the system shows the same malfunction implies that only the hard disk recovery service can do.

The differences between these  hard drive recovery solutions can be listed with respect to prices, functionality, hard disk recovery mechanism, and working, cases addressed, and others. Basically, the high ending products and services would help and not with the cheap ratings.

Stellar Information Systems Limited offers you the most efficiently working hard drive recovery tools. Through the scanning ability of data recovery software and clean surroundings of Class 100 Clean Rooms, you can benefit the best hard disk recovery of the industry.

The hard drive recovery software will do a perfect scan which is available for different operating systems and under the data recovery service; you would get the apt treatment to the hard drive.

When you try to access data from your computer hard drive, you may encounter certain error messages and the drive is displayed as RAW. In such situations, your important files and data can not be accessed from the drive.

When your hard drive is shown as RAW, it might show you the following symptoms:

'Invalid media type reading drive.' Error message

'Sector not found' error message while accessing any file.

'Disk is not formatted. Do you want to format it now?'

File names contains strange characters.

In such situations, you need to opt for RAW Hard Drive Recovery. You can effectively achieve that with Hard Drive Recovery software that are specifically designed to meet recovery requirements of different users.

These software are capable of extracting your lost, missing or inaccessible hard drive partitions/volumes and complete data. Hard Drive Recovery software are generally easy to use and enable you to have ‘Do It Yourself’ data recovery.

You shoud only select hard drive recovery software that offers RAW Hard Drive Recovery support. RAW data recovery is used on hard drive file system’s logical structure corruption that causes serious issues (even post correction like index correction by chkdsk) or when logical structure gets overwritten. The RAW recovery process is carried out as the critical file system information about each file as name, type, size, number of clusters (for large files), location and more. In case of corrupted directory structures and missing file information, it is impossible to recover the original file and folder names as they are not available. So, the regular tools for data recovery do not work in this situation.

The scan method used by RAW data recovery incorporates sequential reading of all sectors on the drive using file signature search algorithm. Almost all file types have unique file header and at times footer signatures. It provides the great option of extracting the confined data that lies within the file header and footer.

Hard Disk Recovery software offered by Stellar Information Systems Limited are the best solutions for all your data loss problems. These software allow you to get your precious data back by carrying out RAW Hard Drive Recovery in few simple steps. With commanding scanning abilities, you would get incredible results with these software. You can get Stellar’s Hard Drive Recovery software for Windows, Mac OS, Linux, UNIX, BSD and Novell Netware operating systems.
