Partition refers to logical division of hard disk and mass storage space into independent parts. Partitioning hard disk drive is useful for installing more than one operating system on computer system. For example – User can reserve one partition for LINUX and other for Windows.
In Microsoft DOS (Disk Operating System) each partition of partitioned disk behaves as separate disk drive. Partitioning computer system hard disk drive can improve disk efficiency because the NTFS (New Technology File System) system used by Windows operating systems automatically assigns cluster size based on the disk size (larger the disk, larger the cluster).
The recognition of partition by system entirely depends on the partition table and boot sector of partition. If partition table or boot sector of partition is destroyed by virus or deleted accidentally, user will not see the partition.
The data recovery software provides partition recovery from NTFS and NTFS5 file systems. Files can be easily recovered from deleted partition, lost partition, missing partition.
A virus is a program that reproduces its own code by attaching itself to other executable files either COM or EXE in such a way that the virus code is executed when the attacked executable file is executed.
Viruses attack on files in following ways:
More recently, scripts written for Internet Web sites and/or included in E-mail can also be executed and infected.
Viruses can attach the files by adding to the end of a file, inserting to middle of file or places the pointer to distinct location on the disk where virus is found.
The working behavior of all viruses is quite similar; first they infect the file and then attack the data. Some of malicious codes are also available in Trojan Horses, worms, and logic bombs that destruct the data.
Viruses that can infect a number of different portions of OS and file system of computer include:
Viruses’ category on the basis of how they infect are as follows:
The media recovery software recovers and restores all files deleted, removed, erased and lost due to virus attack with ease.
(c)OS Installation Error
Operating system encounters an error message during installation like:
Some common error messages may be displayed on Computer startup are:
NTFS Data recovery software recovers all the lost and deleted data from hard disk drive with ease.
(d)Logical bad sector HDD
The computer’s hard disk drive bad sector can not be used due to permanent damage. Logical bad sectors can be detected by disk utility software such as CHKDSK or SCANDISK on Microsoft systems or using bad blocks in UNIX OS. Once the sector has been marked unusable it can not used by OS at later stage.
Logical bad sector hard disk drives can not be used in future and data also gets damaged and corrupted. NTFS Data Recovery Software provides solution to recover and retrieve data back from logically bad sector affected storage media with ease.
