Methods Of Disk Striping In Microsoft Windows

Microsoft Windows NT-based operating systems create a hard drive file system

, known as stripe set. It is created by dividing the data into blocks and then spreading them in fixed order through all hard drive in RAID array. By adding information and data to all the partitions in set at same rate, disk striping provides best performance of all the Windows disk management strategies. Disk striping helps you to recover your data if any of the disk fails in array. But if more than one drives fail, data become unrecoverable and you need to opt for hard drive recovery solutions to get your mission-critical and valuable data back.

Server versions of Microsoft Windows operating system (including Windows Server 2000 and Windows Server 2003) enable you to set fault tolerance hard drive striping with parity that stores both stripped data and parity information on different disks of RAID array for redundancy. The disk striping can be done either with parity of without parity:

Striping with parity

You can create the stripe set with parity on minimum 3 and maximum 32 drives. A single stripe on stripe set with the parity could be located on every physical disk. Total amount of hard drive space used for storing the parity information is equal to size of a partition in set. Nevertheless of the number disks used in stripe set with the parity, data is retrievable only if a single disk is lost. Such cases need Hard Drive Recovery to be handled.

The FTDISK.SYS (Fault Tolerance Driver) makes loss of a disk partition in stripe set with the parity invisible, you could write and read data from a set with lost information as when it was healthy. But stripe set does not remain fault tolerant. Loss of any of the remaining hard drive partitions would cause data to be unrecoverable in stripe set.

Striping without parity

This process does not provide fault tolerance; if any of disk in stripe is damaged or bad, whole disk stripe would be lost. The stripe set could be created on minimum 2 and maximum 32 disks. A single stripe on stripe set could be located on every physical disk. It provides excellent performance of all the Microsoft Windows disk management strategies.

In such situations, data loss require Hard Drive Data Recovery to be sorted out. The recovery is best possible using advanced and powerful third-party applications, known as hard drive recovery software . They work in most of the data loss situations and retrieve all types of lost files, documents and other data.

Stellar Phoenix Windows Data Recovery is the most advanced and powerful tool for assured recovery. It recovers data from FAT32, VFAT, NTFS and NTFS5 file system partitions. The software is compatible with Microsoft Windows 7, Vista, 2003, XP and 2000.
