The hard drive of your computer, be it the desktop or laptop, whether running on Windows or Mac operating system, is the main data storage device that saves all the data generated during the long course of its usage. If we see the evolution of hard drives, the technology has evolved remarkably. From the disk drive technology to the modern day SSD (Solid State Drive) technology, hard drives have changed a lot. We see the hybrid drives as well, where the mix of the two (HDD + SDD) is also possible. Many new makes/models of hard drives have appeared in the market and many brands have emerged. However, for common users, the basic purpose to save data; their valuable files, folders, songs, videos, photos, databases, accounting details and so on, is going on.

We have some of the world’s best hard drive makers, such as Western Digital, Maxtor, Seagate, Quantum, FUJITSU, Apple, TOSHIBA, IBM, SONY, SAMSUNG, and hp. These hard drive manufacturers innovate their own technologies what we call as the interface of these devices, such as IDE, SATA, SCSI, SAS, eSATA.

Whatever be the interface, make or model, or manufacturer of your hard drive, the most important aspect is the safety and security of your data lying in the hard drive.

‘Hard drive may fail at any moment and your data is lost.’ This is a hard, but obvious fact. Unless you take precautionary measures, such as up to date data backup, you are sure to lose them all without any warning.

However, the good thing is that Stellar Data Recovery is here for your rescue. The Stellar Phoenix range of Windows and Mac hard drive recovery software can recover all your lost and deleted data and bring you back to normalcy.

Data Saving Mechanism in Your Computer

What makes a computer run is the operating system installed on its hard drive. In the world of computers, users love two of the biggest names, Windows and Macintosh. These two operating systems have dominated the world of computing for past few decades.

Whether Windows or Mac, data storage mechanism in both of them is almost the same; the only difference lies in the file system that the individual OS create. Windows OS creates NTFS, NTFS5, FAT12, FAT16, FAT32, and VFAT file systems, while Mac creates HFS, HFS+, HFSX and HFS Wrapper.

When the OS gets installed, file system enables creating physical partitions (drives) in the hard disk, where we save our valuable data. The file system also creates and maintains a registry entry of all the data. This helps in opening a file, making changes to the file. Even when we delete a file, the registry entry is generated. In all such cases of logical cases of files or folder (or data in any form) deletion, the OS maintains the records. Hard drive recovery software make use of this information to recover the lost or deleted files and folders.

Let us see how data loss due to logical cases occurs.

Logical cases of Data Loss

The logical cases of data loss occur due to software related issues. In this case, the hard drive is in perfect working condition. May be there is issue in the file, or the application, or in the operating system, and hence the data is in an inaccessible state. Mentioned below are some of the reasons of logical data loss.

Accidental Deletion – This is the most common case of data loss. Many times, unintentionally or intentionally, we delete data from the computer, just to realize few moments later that the data we deleted was of utmost importance.

Formatting of the Hard Drive – When we format the hard drive, the operating system gets reinstalled to a completely new state. The file system also gets freshly installed. This erases all the data, which was there earlier.

Lost Partition – Formatting an individual partition also makes it to lose and hence, the data within it. This is also a case of logical data loss. Many times, due to users’ mistake, we lose such a partition.

Operating System Crash – At times, due to corruptions in the operating system itself, it stops functioning the way it should be. In such a case, you can no longer get access to the system and the data. This we call is a state of unbootability.

Virus Infection – Viruses, trojan horses, malwares etc. are the biggest threats to the smooth running of your computer. Unless very strong and effective antivirus measures are in place, they attack your computer and destroy the file system, eat up data, consume valuable memory space and cause huge data loss. This is a deadly case of logical data loss. The ultimate resolution left is to go for a clean operating system reinstallation, which ultimately ends with further data loss.

Recover Files from Logically Failed Hard Drive

Stellar Phoenix Windows Data Recovery and Mac Data Recovery can recover all PERMANENTLY deleted data from your PC or Mac. Available separately for the Windows and Mac OS, these software smartly handle all the cases of logical data loss including deletion, data loss due to hard drive formatting, OS reinstallation, partition loss, and virus infection.

The software use scan engine that fetch the lost information with excellent recovery algorithm and get back all the lost and deleted data, be it your files, folders, memorable photos, videos, songs, database files, accounting details, and others.

You may wish to check the software for a try. On the other hand, maybe, you or some of your family or friend is experiencing data loss. Here are the Free Demo versions of the hard drive recovery software. Download and scan your PC or Mac with the free demo version of the Stellar hard drive recovery software and see all files and folders you can recover with. The software enables smart preview option right within the software after the scanning of the selected volume or the entire drive is over.

What if, It is not a Logical Case of Data Loss?

In case you hear continuous clicking or grinding sound, your fear is affirmative. This is not positive sign. The hard drive is an electro-mechanical device that contains parts like aluminum disks, read/write head, spindle motor, which rotate at very high speed. Such noise indicates that there is internal mechanical failure to the hard drive and it may die soon or may fail to work at any instant. In such a case, it even fails to respond to boot up or power on. Technically, this is a case of physical data loss, as the data recovery can only be possible through invasive procedures. It requires CLASS 100 Clean Room and experienced data hard disk recovery experts.

If you hear clicking or grinding noise from the hard drive, prepare to take complete backup of your data to a new hard drive at the earliest. Once the hard drive gets physically damaged, physical recovery is the only way out. It is suggested that do not attempt to open the hard drive of your own.

Stellar Data Recovery has been offering hard drive recovery services for physical data loss in its CLASS 100 Clean Room environment under expert hands.

 

Hard Drive Interface Details

 IDE (Intelligent Drive Electronics   or Integrated Drive Electronics)

Western Digital first developed IDE or the Integrated Drive Electronics in association with Control Data Corporation and Compaq Computer, which appeared in Compaq PCs way back in 1986. This technology enabled the integration of the drive controller into the hard drive, while earlier there was separate controller connected to the motherboard.

 

 SATA (Serial Advanced   Technology Attachment)

SATA is the computer bus interface used to connect host bus adapters to such as hard disk drives and optical disk drives. SATA communicates through a very high speed serial cable over two pairs of conductors.

 

  SCSI (Small Computer   System Interface)

Most commonly used for hard disks and tape drives, SCSI interface standard connects and transfers data between computers and other peripheral device.

 

   SAS (Serial attached SCSI)

SAS is a point-to-point serial protocol that came as a replacement to the older Parallel SCSI. SAS moves data to and from hard drives and tape drives. They offer backward compatibility with SATA as well.

 

   eSATA (Power over   eSATA,   Power eSATA, eSATA/USB Combo,              eSATA USB Hybrid Port)

eSATA is a combination connection mostly for external storage devices, which is designed to work with both SATA and USB.
