In life we will encounter many problems of data recovery, data recovery can be based on different types of faults can be divided into: hard soft failure, hard disk physical failure.In the data recovery when there are a lot of knowledge we should all master.
Hard drive data recovery
Soft fault:
File Recovery: The main partition is wrong, wrong format, system recovery disk error recovery system, accidentally deleted files, partition error cloning, partition table (MBR) loss, boot sector information (BOOT) loss, virus damage, hacker attacks andmalicious programs, information is lost Raid disk array server, and suddenly power-down, memory overflow, software conflicts, forced shut down or crash and so on.
File Recovery:
Office series document damage, Microsoft SQL, Oracle, Sybase, Foxbase / pro database file corruption, etc.,
Pictures and other files corrupted Zip, MPEG, asf, RM files and MS Outlook, Exchange e-mail, and so recover
Password Recovery:
Windows 2000, Windows XP and other operating operating system password recovery
zip, rar, Word, Excel, Access, pdf password recovery and other documents and so on.
Hard fault:
(1), fault forms:
A. CMOS do not recognize
B. often a "Kacha Kacha" the head impact
C. motor does not turn, no sound after power
D. read-write head dislocation caused by incorrect data
(2), hard disk hardware failure Category:
A, plate body failure: (Class 100 clean work required in the work environment)
Head burned, the aging head, head chip damage, disk injury
Head offset, disc scratches, magnetic distortion; servo information is lost (also called firmware information), etc.
B, the circuit board fault:
Damage the circuit board, chip burnout, needle break (the most simple direct replacement of the same type or same series of circuit board)
U U disk data recovery disk, USB, XD card, SD card, CF Card, MEMORY STICK,, SM card, MMC card, MP3, MP4, memory stick, digital camera, DV, micro hard drives, CD-ROMs, floppy disks and otherstorage devices.Hard drives, removable disks, flash drives, SD cards, CF cards and other data medium damage or circuit board failure, head offset, disc scratches, etc., using open body replacement, loading, positioning and other methods of data recovery.
Unix data recovery platform based on Solaris SPARC data recovery platform based on Solaris INTEL data recovery, restore SCO OPERNSERVER data, HP-UNIX data recovery, IBM-AIX data recovery.
Linux Data Recovery Linux operating system for data backup is an important Linux system administrator duties and responsibilities.The traditional method of data backup Linux servers a lot, but also a variety of backup methods.Common Linux data recovery backup only the data compression through TAR command to copy the disk to the other regions.There are safer approach is to double automatic backup, not to all the data stored in a computer, or if this computer's hard disk for physical damage, then all data will be gone.Double backup so data security is a commercial server, the basic requirements.
