Basic disks can be upgraded to dynamic disks; however, when this is done the disk cannot easily be downgraded to a basic disk again. To perform a downgrade, data on the dynamic disk must first be backed up onto some other storage device. Second, the dynamic disk must be re-formatted as a basic disk (erasing all data).
A basic data partition can be formatted with any file system, although most commonly BDPs are formatted with the NTFS, exFAT, or FAT32 file systems. To programmatically determine which file system a BDP contains, Microsoft specifies that one should inspect the BIOS Parameter Block that is contained in the BDP's Volume Boot Record .
When a disk fails, erased data is rebuilt using all the operational disks in the array, the bandwidth of which is greater than that of the fewer disks of a conventional RAID group. Furthermore, if an additional disk fault occurs during a rebuild, the number of impacted tracks requiring repair is markedly less than the previous failure and less ...
In the adjacent diagram, data are concatenated from the end of disk 0 (block A63) to the beginning of disk 1 (block A64); end of disk 1 (block A91) to the beginning of disk 2 (block A92). If RAID 0 were used, then disk 0 and disk 2 would be truncated to 28 blocks, the size of the smallest disk in the array (disk 1) for a total size of 84 blocks.
Ranish Partition Manager is a freeware hard disk partition editor, disk cloning utility, and boot manager, that gives a high level of control for creating multi-boot systems. [1] [2] It is available on the freeware live CD SystemRescueCD and the Ultimate Boot CD (not the Windows version). It runs under MS-DOS, PC DOS, DR-DOS, or FreeDOS.
In computer data storage, a volume or logical drive is a single accessible storage area with a single file system, typically (though not necessarily) resident on a single partition of a hard disk. Although a volume might be different from a physical disk drive, it can still be accessed with an operating system's logical interface.
