Hard drive crash can lead to loss of data stored in the hard drive. Hard drive failure, or crash can happen either due to physical errors or due to logical errors. Mechanical / electrical failures occur due to wear and tear of the moving components / electrical components of the hard drive (especially the motor / spindle and read/write head), hardware failure, faulty handling such as dropping the device, operating the device in extremely humid or overheated rooms can lead to failure of the hard drive. If the hard drive is not being detected in the BIOS when you try to boot, you can infer the reason for non-booting to be physical failure. Cranking noise while attempting to boot the device is another indication of physical failure.
Logical reasons such as hard drive corruption, using incompatible utilities, software malfunction, virus or improper shut down can result in hard drive failure. However, in the case of hard drive failure due to logical errors the hard drive will be detected in the BIOS.
Technically, you can recover data from a dead hard drive irrespective of the cause. You can recover data lost due to logical reasons using data recovery software. Data recovery services are available to recover data lost due to physical failures. The following scenario will help you familiarize with the data recovery process from a dead hard drive.
I am not able to access the data stored in my Maxtor hard drive. Though it is being detected in the BIOS, I am not able to access it. I have been using this hard drive for the last two years and have stored all my data in this machine. The file system is NTFS and the operating system is Windows XP. Is it possible to recover the lost data from dead hard drive?
Do not worry. You can recover data from dead hard drive using Remo Recover Windows. This software with the most advanced scanning algorithm traces and recovers lost data from failed or dead hard drive quickly.
However, if you try to reboot the system further, this could lead to overwriting of the lost data.
Hence for best recovery results:
Windows Data Recovery software is capable of retrieving data lost from hard drives, external hard drives, IDE/AT, SATA/SCSI hard drives, flash drives and from all types of memory cards. The software supports recovery of data from hard drives by popular brands including Seagate, Western Digital, Maxtor, Toshiba, Samsung, Hitachi and many more.
Windows Data Recovery Software is capable of recovering data from Windows Vista, Windows XP and Windows 7. The software is read-only and does not damage your hard drive. Handy features such as disk imaging, disk cloning and disk cloning helps in recovery data from hard drives with bad sectors and in quick recovery of deleted files. For recovering data from FAT file system you can use FAT Data Recovery.
