Hard Drive Crash

DATARECOVERYUNION.COM07 mins

Hard Drive Crash Sometimes a hard drive may experience failure or sudden crash without any warning, but many times there are warning signs that will let you know when to take action. Changes in performance, intermittent failures, or unexpected blue screens are major signs that the hard drive may be dying out permanently. The most obvious warning sign with a hard drive is unusual clicking, grinding, or scraping noises.

In practice, the term hard drive crash often refers to both mechanical or electrical failue and logical failure. The case of mechanical / electrical hard drive crash is the worst, it requires professional help of data recovery service, recovery programs won’t help.

Hard Drive Crash Signs

If your PC is experiencing any of the following signs of impeding doom then you must run (not walk) and grab CDs to burn backups of all your essential data.

Sign 1 – You hear high-pitched whining, loud clicking or grinding noises coming from the drive
A normally operating drive will make a smooth “whirling” sound as is spins up or down. But if a drive has a grinding or clicking sounds (the Read/Write heads scraping too close to the magnetic platters), then your drive is sick and is on the way out.

Sign 2 – You see the infamous “Blue Screen of Death“, repeatedly
BSODs (Blue Screens of Death) are actually called “Stop” errors and they only appear when your Windows system is experiencing severe software or hardware issues. Often BSODs can cured with a careful “Repair Install” of the Windows operating system or by removal of a bad device driver. But if these software fast fixes don’t seem stick, then your hard drive is usually on its last legs

Sign 3 – Your computer keeps re-booting on its own
I admit, I have only seen this problem a few times in my 18+ year career and in all instances it was due to hardware issues. Once it was a dust covered motherboard, and another time an overheating processor. But all the other times it was due to bad drives.

Sign 4 – Your system keeps having frequent freezes or hang ups
You are working along just fine, and then suddenly everything comes to a halt. The program freezes up on you. Your mouse and keyboard seem to stop responding. The only solution is to reboot.

Sign 5 – Error message: hard drive is not formatted
This a fun message that you will get when you start up your machine. You maybe able to restart and get it to boot into Windows a few more times but this error is “fur-sure” sign that you drive is very close to death. And by the way don’t try to format the drive! You will lose all your data.

Sign 6 – Error message: boot drive or device not found or drive cannot be accessed
This is another favorite of mine. You can check the CD/DVD trays or the floppy drive to make sure no stray disks are stuck inside. You can also check the BIOS to make sure the system is booting from the hard drive first. If all these tests are no-good, then the drive is a goner.

Sign 7 – Errors: Operating system not found or Missing Operating System
This is a bad one. Even the Microsoft technical support knowledgebase has only got a few causes for this error message. Basically your PC can no longer detect the hard drive or the drive is too severely damaged to read (DOA).

What to do if your drive has any of these signs?

1) First, listen up, if possible, BACKUP YOUR FILES NOW!
2) Create a boot disk and run Windows Scandisk and set it to automatically fix errors. If it finds more than a few bad sectors then see the point above
3) If possible download and use a hard drive diagnostic program. All the major hard drive manufacturers have free utilities on their websites.

WARNING:

You should never open the cover of a failed hard disk drive in attempt to repair, salvage or recover data. Today’s hard disk drives tolerances are very tight and the materials used inside are so technologically advanced that even the smallest speck of dust, contaminants or even gaseous can disrupt the delicate balance of the drives ecosystem. Any such disruption not only destroys the drive but all the data contained on it.

SD Memory Cards

DATARECOVERYUNION.COM08 mins

SD Memory CardThe SD memory cards known as the “Secure Digital” first began as miniature cards. Afterwards the new and advanced form of the SD memory card SDIO “Secure Digital Input/output” was introduced into the market. The SDA “Secure Digital Association” included new features and technology to the SD memory cards. The SDA included new varieties of card functions. These new card functions included wireless “Local Area Network LAN” devices, cell phones, GPS receiver, digital video camera etc. The memory card readers that were used in the Secure Digital devices connected to the Universal Serial Bus (USB). The Windows Operating System detects and manages the SD (Secure Digital) memory cards through the driver called the (USB) Universal Serial Bus mass storage. The (SD) Secure Digital host controllers are supported by the Operating System. The Operating System connects the host controller SD to the Peripheral Component Interconnect (PCI) bus. When the SD-host controller is detected by the operating system, the “SD Secure Digital bus driver” is loaded by the operating system OS. When the SD card is inserted by the user, the windows Operating system loads two drivers the “Storage mini-port” and the “SD Secure Digital Storage Class”. These two drivers are loaded on top of “Bus driver” by the Windows Operating System. On the other hand if the SD memory card of a different function like the wireless Local Area Network (LAN) or the Global Positioning System is inserted by the user, then the Windows Operating System loads the driver that is supplied by the vendor. It is necessary that both the vendor supplied and the native drivers in the (SD) Secure Digital stack communicate with “Secure Digital Bus”. The device drivers call the routines to communication with the “Secure Digital Bus”. These routines are called in the static “Secure Digital Bus library”. When the SD Secure Digital drivers compile, it is necessary that they link to the “Secure Digital SD Bus library”. There are some limitations for the SD device drivers. The “Host Controller Register” is not directly accessible by the Secure Digital device drivers.

The SD device drivers call the routines of “Secure Digital Library”. Then the Secure Digital Library forwards the Secure Digital commands to “Host Controller”. Music can be stored in the Flash Memory card and it is most advantageous than storing it in the Hard drives.  The SD flash memory cards consume less power and are more portable. The SD flash cards also have resistance to shocks. The SD card facilities its users and they can easily record the data to their personal liking like music, pictures. The users can easily carry and move the data with ease and comfort. The SD memory card has the technology to fulfill the requirements of the future networked society. The tiny SD memory card provides many advantages to their users. These memory cards are highly compatible and they can link to different digital equipments. Because of the compatibility of the SD memory cards, their usage is more likely to expand even more in the future. The SD card has now become a standard of memory cards that are used for digital connectivity. In the near by future, the SD cards will be universally accessible to more wide array of Multimedia data. The size of the SD memory card is approximately 24mm x 32mm x 2.1mm. The design of the SD card is very compact and slim. Therefore, they are easy to handle and the user can easily transfer the data.

The devices that are compatible with SD card can play video clips & music with the help of “decoder software”. The DVD & CD players use “drive mechanism” while the SD memory cards do not require “drive mechanism” to play the video clips. So, this gives the product designers more freedom and they can be more creative and innovative. The other popular form of the SD memory card is the miniSD memory card. The size of the mini-SD card is approximately 20mm x 21.5mm x 1.4mm. The miniSD card is smaller in size than the SD card.

The SD memory cards have different recording capacitates, their capacity reaches up to 8GB. The large capacity helps to store the High quality videos. The demand for high capacity SD cards with fast data transfer speed has increased because of the increased digital content range. The SD cards also have the technology of “Copyright Protection”. This “Copyright Protection” technology enables new distribution system. This provides safety and security to the illegal copying of the data.The SD card has built in technology called the Key Revocation. The SD memory card has “Control Circuit”, which allows to read & write the after the detection of the external devices. The data is written and read within the “protection area” of the card. The authentication among the digital devices has to be enabled so that the SD card could be accessed.
