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.

Stellar Information Systems Limited offers industry’s best hard drive recovery solutions and services. It offers Stellar Phoenix Windows Data Recovery, which is a robust data recovery application. The software supports Windows Vista, XP, 2003 and 2000. Stellar’s data recovery service is provided under controlled lab environment of Class-100 Clean Rooms.

Simpson Raid is a freelancer for Stellar which offers data recovery software and file recovery programs for different OS and file system.

If your computer does not have a data recovery disk, then you will face problems once you lose a file that you desperately need to recover. Such disks guard your computer from drivers, system components, drives, and application troubles. One can differentiate two types, one where operating system files can be recovered and another where data files are stored.

The key of course is to back up your system. Once you do so, recovering data such as emails, text files, or anything else you can think of is very easy. Any old rewritable CD where data or any other recent saved files can be written and re-written on it again and again is suitable for this job.

Of course, there is another kind of data recovery disk saves things such as deleted partitions or even corrupted files. Such a disk will most likely contain data recovery, disk image, password resetting, partition management, system utilities, data erasure as well as network access tools.

Anyone can buy a data recovery disk varying on the kind of recovery that can be made. Most disks have certain specializations. You can set them to recover images only, or e-mails only or anything from your hard drive. You can even recover data from any removable disk.

The operating system disc (usually drive C) can also be used to recover data. One just needs to boot from there then you run any of the following depending on what kind of recovery you want to do. These run commands are either fdisk, chkdsk, or testdk. Just press F12 when the operating system is starting as you turn the PC on. You could also boot from a CD or your disk. That will enable you to get inside and fix the kinks out.

There are however, some special circumstances when data recovery is no longer possible. And this is funny because there are those who think that banging or dropping the computer, or even heating it can fix it. Of course most of the time, this just makes the problem worse.

Of course, a computer that has been hit or fallen will have physical damage. During this kind of circumstances, your hard drive might just be damaged. Then you will never be able to get back that lost data. The most you can try to do is to pay the guys from crime scene investigations to have a look at your data. But that is of course highly unlikely.

Therefore, as a warning, one should never do anything silly as physically banging on the PC if you are only looking for attention. Simply use disk to back up your data most of the time as well as other tools for recovering data. Remember though that some day, your pc will go bust. This is why one must be ready by backing up or having a data recovery disk.

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.
