Hard Disk Initializing ? Error and Recovery

As the technology advances, computers are getting much faster by the day. As compared to early computer systems, modern systems boot so fast that they attempt to auto-detect the hard drive. Before the hard drive is ready, operating system starts. In such situations, if hard drive is failing, problems might go undetected. If system BIOS is taking sufficient time to initialize the hard drive, probable issues could be related to hard drive or mere BIOS settings. In some of the critical situations, you might need to replace the hard drive and restore lost data from backup. But when backup raises corruption or unavailability issues, it necessitates the use of Hard Disk Recovery solutions.

You might receive the below mentioned error message while attempting to start your system:

“Hard Disk Initializing; Please wait a moment...”

If you encounter this message, but the boot process proceeds as normal, you need not to correct or perform any task. But if system hangs after this error message occurs, hard disk needs to be troubleshot.

To solve hard disk issues, you should consider these recommendations:

You need to check if hard disk is detectable by controller. Use BIOS auto-detect feature. If hard disk is not auto-detected, it could be hardware issue. However, if BIOS can detect the hard disk using auto-detect feature, the issue could be that hard disk is not partitioned and formatted (It generally occurs with a brand new hard disk). You should partition and format the hard disk in such cases. Try to boot the hard disk using bootable disk and run chkdsk to check and repair file system inconsistencies. If chkdsk cannot correct it, reformat the hard disk and restore from backup. Use Data Recovery applications if backup fails to restore. If hard disk doesn’t boot up, check for jumper settings and hard disk cables. If this is not the issue, consult Hard Disk Recovery technicians for recovering lost data (if backup gives errors or is absent). They provide disk recovery services, in which a failed hard disk is analyzed and intermediately repaired for extracting lost data.

It provides read-only and comprehensive recovery applications for operating systems including Windows, Linux, Novell, Macintosh and UNIX. Also, it offers confidential Hard Disk Recovery service, facilitated by Class 100 Clean Rooms, high-tech tools and techniques and developed inventory.

Really? You Don’t Need A Website Disaster And Recovery Program? Why?

If you answered YES to that, you're dead wrong my friend. Let me prove it to you by giving you real true-to-life examples.

Recently, I asked this question to one lady webmaster named Dorothy and she said quite simply,

"Well, why should I do that? My webhost said that they guarantee 99.9% of the time, my website will be OK. Besides, I don't know how to do it if that's technical stuff. So why should I care?"

That is the mindset of many people like her who really believed that the 99 % uptime guarantees found on the promises page of their webhosts is already their website insurance.

First of, what's a "Disaster and Recovery Program"?

It's all about a business owner's plan of actions, systems and procedures that ensures business continuity when disruptions and disasters arise in the normal course of business.

Every major corporations and businesses worldwide have this on their yearly agenda as part of their risk management assessment. It's also known as the "Business Continuity Program" in the corporate world.

I know your online business and your websites are important to you. So why then should it not apply to your online business as well?

You know that many times, disaster strikes us when we least expect it. Sometimes it even happens when you have a major product launch or a full-blown advertising campaign when, all of a sudden, your websites went down and boom, all your efforts and investments went down the drain as well.

If hackers happen to pick your site for fun and notoriety, managed to break in to deface it or release worms, Trojan horses, DDOS attack bots and the likes that damage your websites as a result, what will you do after?

What about fires in the datacenter where your server is located or maybe a hard disk failure on your web hosting server? There are even cases of errors in technical configurations, substandard server hardwares, overcrowded hosting servers, technical incompetence of support staff and other problems your host wouldn't tell you about.

These disasters have ruined too many online businesses in the past. And my websites are not spared as well. Believe me when I tell you that it happened to my websites many times even on my own dedicated server! It only shows that disasters do happen and even your webhost sometimes cannot do anything about it.

Website hacking and defacing, viruses and worms, server crashes, server hardware failures, datacenter fires, network failures, electrical faults, technical support errors, long recurring service downtimes and other website disasters can immediately put you out of business. And that's just one of the effects. Not to mention loss of face, loss of opportunities and loss of time.

Why?

Because downtime is just not acceptable these days. Your customers and visitors can't wait all the time for you to be back online. If they can't find you, they can't buy from or trade with you and going to the competition is easy as a click of a mouse. Your advertising and promotional campaigns are put to waste because of your dead websites. Lots of money are lost in recovery and restoration as well as in lost opportunities that you will surely miss out.

That's why we all need to make the planning for disaster and recovery a high priority item in our online business especially if you are seriously making a lot of money from it.

By the way, I'm not scaring you at all. But think about it for a moment. Imagine a situation wherein you and your websites are in total chaos, you don't know what to do because you don't have a website backup, you don't have a restoration plan and you don't really know who to run to or talk to about it.

You see, each webmaster should have a comprehensive plan of action. Your disaster and recovery program should not only target your webpages (html, images, photos, audios, zips and other files). You should know that there are other website components that you need to take care of too.

For example, many websites nowadays have MYSQL databases installed to store and manage their customers, sales, products, files and visitors data among other things. MYSQL is free to use so many people naturally are using it for their website scripts. There is a good chance that you are using or have used it too, right?

So when disaster strikes, not only are your webpages at risk, your precious MYSQL databases are also at risk. Most of the time, webmasters have local backups of the webpages, files and scripts on their hard drive which can be easily restored. But MYSQL databases need a special backup procedure for you to extract it straight from your website control panel. You can't easily create it and upload it like your html, pdfs and zip files. Your web hosting server creates and grows these databases for you real time. So if you're not technically inclined to know this as a webmaster, you might disregard it and face the risk of loss in the future. Yet losing your business data is like losing your business continuity. Once it's lost, you'll find it hard to recover.

Another website component is your website scripts. They need a disaster and recovery plan too. Say for example you purchased a PHP script that has an auto-install auto-update feature from the seller. Most often than not, you have no copy of this script on your local harddrive (since the seller might have installed it for you for free) much more the version updates that are automatically applied to your website each time the seller releases a new one.

If you fail to backup your whole PHP script configuration, then it will be very hard for you to restore this script to its last state. Imagine getting back to version 1 or older version of your scripts. You'll end up paying the seller or a top programmer lots of money to restore this for you if you're even lucky enough to have the script from the seller again for free. If not, you have to pay for it again.

Crazy eh?

What a waste of money just because you don't have a disaster and recovery plan. Not only that. You will lose face, customers or visitors, momentum, opportunities and most of all, time to recover and restore everything to its last working condition.

You sure wouldn't want to go back to where you started, would you?

So here are five (5) simple steps you can easily do to setup your own Disaster and Recovery Program for your online businesses:

1. First, REALIZE that your websites and all the other components are always at RISK. If you still believe your webhost that nothing can happen to your website no matter what, you won't be able to know until you've lost everything. I know this and I speak by experience. If you can sleep at night well knowing that as a webmaster, you're in control, then it really pays to do it yourself. If you're still not convinced, answer this question: "Would you really put on some stranger's hands the fate of your online business?" Remember that, most of the time, you've never even met or talk to your webhost.

2. Second, BACKUP ALL your website files, scripts and databases on your local hard drive, another remote server or another offsite media. This means you'll download, store and update these files from time to time. You have to do this patiently on schedule (better once a week or best daily if you have high traffic database-driven websites). You will use these backup files to restore your website to its latest state when disaster strikes. Usually, web hosting control panels like Cpanel, Plesk, Ensim and Webmin have a backup and restore facility page where you can do this. Please check your control panel manual for details.

3. Third, LEARN how TO recover and RESTORE your websites to its latest state. Since your online business is important, you must be able to quickly recover from any disaster. A quick restoration plan should be in place and rehearsed during the "good times" so that when "bad times" come, you're well prepared for it. Remember, if you know how to build your websites, you must also know how to rebuild it too. This is needed not only during disasters but also if you're transferring to another web host or web server.

4. Fourth, COLLABORATE, if you're not a programmer or technically knowledgeable about websites, scripts and MYSQL databases, with someone who has that knowledge. When disaster strikes, you should be able to quickly pull someone who can do the technical stuff for you if you don't know how. My suggestion is to get someone from Elance.com or Scriptlance.com. Since these sites are working on a project bidding system, you'll get better service at lesser price. There are risks involved here also but that's another matter. What's important is for you to know the places where to get help when you need it.

5. And lastly, STICK WITH YOUR PLAN and do it DILIGENTLY. You can never tell when problems will occur so you have to be ready all the time. And this can only be achieved by being serious to the above four (4) steps.

Remember, this disaster and recovery plan is your own insurance for your online business. You don't have to pay someone to do it for you. You can do this if you'll just realize that your online business is always at risk and it's important that it continue so that you will benefit from it in the long term.

As you become triumphant over any online disasters you will be facing, you will know how good it is to be in total control.

And that, my friend, is a great feeling.

‘Values in super block disagree with…’ BSD Error and Recovery

The UFS Superblock contains the basic configuration and size information of file system. UFS1 Superblock is located at sector 16 of the hard disk with 2,048 bytes allocated to it. UFS2 super block is found to be little simpler and removes many unused fields. It is located at sector 128 of the hard disk. A BSD system cannot boot if its super block is corrupted. In such cases, you might come across errors which suggest you running fsck manually. The command looks for alternative super block to repair the corrupted volume and hence to allow the system to boot. But if the command fails to repair the volume, your data will remain inaccessible. To recover this lost data, you need to use BSD Data Recovery software that can extract the lost data.

For an instance, consider that you use a BSD based computer system. When you boot the system, you observe that the auto file system check process and you come across the similar error message:

“/dev/da0s1a: BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH

THOSE IN FIRST ALTERNATE

/dev/da0s1a: UNEXPECTED INCONSISTENCY: RUN fsck MANUALLY”

After this, the auto file system check process fails and the boot process halts. You experience that the system is put in single user mode. This issue might occur both in UFS1 or UFS2 file system.

Cause

The prime cause of this error to occur is that the super block is corrupted. This could occur due to any of the following possible reasons:

Unexpected system shutdown You are using UFS1 file system and have installed FreeBSD 5.x and FreeBSD 4.x on the same system. The issue might occur if you try to mount 4.x partition under 5.x because they possess different super block format

Solution

To solve the existing issue, run the following commands:

/sbin/fsck -y /dev/da0s1a /sbin/fsck -p

If the commands run successfully, you will be able to boot into the system. But if it doesn't, you need to either use your backup or scan the disk using a powerful BSD Recovery utility to recover the data. BSD Data Recovery product employ advanced algorithms to locate and recover lost data after any logical crash case.

Stellar Phoenix BSD- Data Recovery is a powerful utility that recovers and restores lost data from UFS1 and UFS2 file system. It is a comprehensive BSD Recovery product that is supportive to FreeBSD, OpenBSD and NetBSD variants. It is an easy-to-use tool embedded with advanced options.

HDD Recovery Tools

This is a situation that every tech support person has faced or will face at least once: a failed hard drive.In this particular case, a user was getting errors like "disk 0 error" and "invalid drive specification."

Here were the other facts in the case:

• The data wasn't backed up.

• The problem came out of nowhere.

• The user had accessed Setup and tried to manually enter the settings for the drive type when"Auto" didn't work.

• There was no startup disk made by this machine.

Repair a drive like that one—even if only long enough to copy its data before you throw the drive in the garbage—is a tough challenge.Compared to buy a new drive,the price of Data Recovery nowadays is still a very expensive option.

While the Freeze it, Hit it, and Drop it options are still experimented with by some, the current size and sensitivity of the newer larger hard drives makes these options extremely risky and definitely NOT recommended for hard drives with a capacity that’s greater than 60GB. And even then some of the operation suggested here should be approached with caution.Getting it wrong by trying to save some money will only end up costing you more if you then decide to pass on your hard drive to a data recovery company...

There are, broadly speaking three classes of data recovery, Logical, Electronic, and Physical.

• Logical

Where the FAT, NTFS or other file structure has been corrupted either by accident

or on purpose or individual filed or folders have gone missing. The hard drive has

not suffered damage to the components of the hard drive itself.

• Electronic

Component failure on the PCB (the circuit board on the bottom of the hard drive)

in the motor or internally.

• Physical

Internal damage to the hard drive, damaged platters, head crashes, damage to

the motor, or head rack signal amplifier. You need a clean room and plenty of

experience to have any chance of a successful outcome here.

Logical recoveries are becoming an affordable option for those people who are familiar with the risks involved with data recovery. Software tools that are now available for this task vary greatly in their capability, complexity and cost.Careful research should be done before any work is done on the damaged hard drive. If you

are able, get another hard drive and experiment. Format it, Fdisk it, delete files and partitions and learn how the data recovery software operates under these various conditions.

Before to start work on your own or your clients hard drive back it up, the backup mantra is one that you all should be familiar with by now! There are tools available to backup (or image) a hard drive that has been fdisked!! Use them. Ghost software is not suitable for this task,then perform your recovery attempts on the image not the original.

For the Electronic damaged,you must need some extra hdd repair tools to exchange the PCB or Head or other components,as far as we know,nowadays one tool called HD HPE Pro produced by SalvationDATA can do the excellent job of exchanging drive's components.Many data recovery companies now using this tool,also nowadays there are many faked tools in the market which price is lower than SalvationDATA,but with bad quality.

As for the Physical problems of the drives,if the situation happened in several years ago,then even the best professional data recovery company will say that they have no choice.But nowadays,the hdd recovery tools grows at a quick rapid speed,there are many tools can do this job now,among them the most famous tools are produced by ACE and SalvationDATA,but it is said that the Data Compass of SalvationDATA is much powerful,which can also support the Raid data recovery,which ACE doesn't has.

So nowadays whether your hdd has logical or electronic or physical damaged,you are no need to worry about your data,because there is always solutions here to find your data back.
