Windows Hard disk Failure and Recovery

Windows is one of the most popular operating system and it is widely used by computers and servers due to its convenience and good performance. Hard drive is hardware placed on all computers storing data and installing program and Windows. When hard disk gets damaged, the result is losing important data or even system. Hard disk problem happens to all computers without any foreshadow and there are a great number of causes of HDD failure such as virus attack, bad sector, sudden power failure, etc.

All HDD problems can be divided into two groups: physical failure and logical failure. This post will explains both and their differences.

Hard drive physical failure

Hard drive contains many mechanical parts which easily get damaged after violently crash or dropping to grand. It has been mentioned just now, sudden power failure may cause severe problem. It’s well known that traditional hard drive writes and read data by way of heads moving forth and back above rotating platters. Normal process of system shut down sends signal to hard disk and heads will withdraw. But sudden power outage forces heads to withdraw from stack of moving platters, which is very likely cause bad sectors and do harm to head and data.

Solution of such HDD failure differs from the importance of missing files. Some users seek hard drive recovery solutions while some want get HDD repaired. However, in fact, neither of them is easy to realize, as certain damage is irreversible and even specialized machines can’t handle it.

Logical hard drive failure

As it suggests literarily, errors or problem happened on logical level. An easy example, hard drive partition becomes inaccessible or corrupted because of file system error. Reasons of file system error are many, which can be virus infection, unplug drive improperly or partition table damage. Windows hard drive failure brings about data loss, as corrupted partition or drive can’t be opened.

It’s easy to fix such issues. Formatting is able to make an inaccessible partition normal again and chkdsk command helps fix file system error. One point should be noted is that Windows data recovery must be done prior to formatting or any other repairing actions; otherwise recovery result will be affected, as files might be damaged.

Hard drive failure repair and data recovery

The most common hard drive damage is bad sector. To some extent, bad sector also can be further divided into two types: logical and physical bad sectors. The former can be fixed by some software, and yet physical bad sector requires professional machines. However, there are still many bad sectors can’t be repaired. Besides, once heads within the hard drive go wrong, it is not workable to get it repaired.

HDD failure won’t be repaired on its own and lost files won’t be recovered automatically either. Thus third party tool or service is needed, for instance hard drive recovery software Eassos Recovery is capable of retrieving missing files from damaged HDD. There are many online and local HDD repairing shops aiming to fix physical problems.

Protect Your Data (Encrypt Your Files)

Medical records, tax documents and other files with personal information are often stored on personal computers. If you don’t encrypt files that include personal information, you risk making yourself an easy target for cybercriminals. Encrypted folders, which are referred to as vaults, can lock down your information, so it’s unavailable to anyone without your password.

Encrypt-Stick is the most advanced portable security application available on the market today. Encrypt-Stick software converts your USB flash drive into a personal vault and the key to access and secure your private files. Encrypt-Stick requires a serial numbered USB flash drive to run. It gives you the ability to create unlimited invisible encrypted vaults on an unlimited number of computers, removable hard drives or networked drives. If a vault is burned to a DVD/CD you can securely access it using the original USB used to create the vault. Encrypt-Stick provides you with the highest level of protection from identity theft, hackers, phishers and will never leave a footprint on the host computer.

With a USB drive in your pocket you can carry around personal notes, in-process documents from work, or even top secret military communications. But a hole in that pocket could quickly become a major security leak. Encrypt Stick 5.0 ($39.99 direct) equips any USB drive with a secure encrypted vault for safe data transport. It can also serve as the key for any number of local vaults on home or work PCs, and it has a secure browser and password manager built in.

Note – Once you’ve activated your software on a particular USB drive you can’t move it to another drive. Before you install Encrypt Stick, you’ll want to select a high- quality USB drive with as much storage capacity as you anticipate you’ll ever need. Conveniently, you can install the Mac and Windows versions of the software on the same USB drive and access your protected files from either platform. Once you’ve downloaded Encrpt Stick (or using an installation CD/DVD) your ready to create an encrypted vault.

Creating An Encrypted Vault

The setup wizard walks you through the steps necessary to install and activate Encrypt Stick on your USB drive. During this process you’ll create a strong master password, something that you’ll remember but that nobody would guess. The password-entry box has a built-in password strength meter to help you make a good choice.

Your home system probably doesn’t have a malicious keylogger running, but if you’re worried you can enter that strong password using Encrypt Stick’s virtual keyboard. For added security against monitoring software the virtual keyboard scrambles the location of the characters.

Encrypt Stick uses your password, along with device-specific information, to generate a unique 512-bit (polymorphic) encryption key. That means your files are protected by two-factor authentication: something you have (the USB key), and something you know (the password). Gaining access to protected data requires both.

The wizard includes a recommended optional step that makes a local backup of the decryption key. That way if you lose the USB drive containing Encrypt Stick, you can still recover encrypted files stored on your computer. Files on the lost drive itself are gone, of course, but at least nobody else will be able to read them.

Vaults for File Protection

On initialization, Encrypt Stick creates an encrypted folder right on the USB drive. When you’ve entered the master password, you can freely move files into and out of this folder or launch and edit the files. Outside of the Encrypt Stick interface nothing is visible except encrypted filenames and encrypted data.

You can also create any number of vaults on any PC or Mac to protect local files on that system. Encrypt Stick acts as a key to open these locked vaults. The product’s main window displays available vaults in its upper portion and offers a view of the unencrypted main file system in its lower portion.

To encrypt one or more files you simply drag them onto a vault. When you copy files into a vault, Encrypt Stick offers to securely erase the originals. The help videos call this “military wipe,” implying a connection with the DoD standard for overwriting files before deletion. Basically, it erases the data and writes over it 7 times for the minimum DoD standard.I It also definitely bypass’ the Recycle Bin, which is sufficient to foil casual recovery of secure files.

For additional security you can set Encrypt Stick to automatically lock after a period of inactivity (10 minutes by default) and require a periodic change of the main password (every 30 days by default). This is near military grade encryption (in a commercial usb casing).

Private Browser

Encrypt Stick includes a built-in private browser. When you’re browsing from a “foreign” computer your favorites, history, cached files, and all other browsing traces remain on the device. Once you unplug the device nothing remains on the host computer.

The private browser doesn’t have every possible feature, but it does support tabbed browsing, and it can handle Flash and other popular content types. I was mildly annoyed to find that Ctrl+Enter in the address bar doesn’t complete an address by adding “www.” and “.com”, but I didn’t find any page that it couldn’t display. I verified that no trace of surfing with the private browser remains behind on a host system.

Encrypt Stick lacks the ability to take private browsing to another level with the option to browse using a fully encrypted secure session. This is what Intel Operators use when they are connected through a compromised network in a shady Internet café (the bad guys won’t be able to sniff out private data from your network packets).

Limited Password Management

Encrypt Stick also includes a password management system linked to its private browser. You can store any number of passwords and group them in a hierarchy of categories, but you’ll do all the work yourself—copying and pasting URLs from your browser and manually entering username and password data (with an option to use the virtual keyboard for passwords).

If you’re setting up a new online account, you can use Encrypt Stick to generate a strong password. However, there’s no provision to adjust the password generator to match a site’s password policies. Key Safe’s password generator lets you set the length and choose which character types to use. It even includes an option to create passwords like “purrPler0ks” that are easy to remember because you can pronounce them.

Full-powered password managers automatically capture login data as you log in to a site manually using a supported browser. I was surprised to find that Encrypt Stick doesn’t offer this level of automation, given that it has total control over the browser.

Key Safe also lacks most features of full-featured password managers, but it does at least have the ability to automatically launch IE, navigate to a saved page, and fill in the login credentials. With Encrypt Stick you must click a link to open the URL in the private browser, then right-click the username and password fields individually to paste in the saved credentials. For some sites this right-click process didn’t work; for others the “fill in” menu choices didn’t appear.

You can import existing passwords from a .CSV file, but it’s not easy. To make use of a similar feature in Key Safe I simply took a file exported from LastPass and rearranged the data columns to the order expected by the import facility. Key Safe can also import directly from several other data types.

Getting my LastPass data into a form that Encrypt Stick would accept took half an hour of manual editing. I did succeed in the end, but only after requesting a sample of the correct format from ENC Security Systems’ tech support.

Why didn’t I just export a sample and study that to learn the format? The export to .CSV feature doesn’t work. It produces a file, but the file is filled with gibberish. After some experimentation I determined that the “gibberish” is actually an encrypted copy of the password data, not the promised .CSV file. The password management feature could definitely use some work.

I also checked the help system to see if it would explain the import process. Or rather, I tried. There is in fact no help system, just a link to the product’s online FAQ. To get help for anything that is not covered in the FAQ you have to e-mail tech support.

Eradicating The Kinks

Encrypt Stick offers a good implementation of file protection by encryption. It uses two-factor authentication, and it can protect portable files on the device itself as well as local files on any number of other computers. The onboard private browser lets you surf the Web on a foreign PC without any risk of leaving private data behind.

The password management doesn’t seem as polished as the rest of the product. It looks good, but it lacks the automation that would make it actually useful. And its import/export system doesn’t work quite right. If you’re looking for a portable password manager, look elsewhere. Still, if you need encryption-based protection for local files and portable files, with private browsing as a bonus, Encrypt Stick can be quite useful.

Pros

Turns any USB drive into secure portable storage. Can create local encrypted folders with two -factor authentication. Private browser allows surfing on foreign PCs leaving no traces behind. Includes password management. Virtual keyboard for safe password entry. Generates strong passwords. Version 4.2 is freeware.

Cons

Password manager requires manual entry of all data. Limited ability to automatically open Web sites using saved credentials. Password import/export facility not working correctly. Can’t configure password generator to match specific password policies.

In Conclusion

Encrypt Stick 5.0 turns any USB drive into secure portable storage for your important files. It also serves as the key to unlock local encrypted folders. An onboard private browser lets you surf without leaving traces. Its weak point is the password manager, which doesn’t seem quite finished. It’s all good though… I have it on my USB stick
