Which disk can be removed and replaced with another disk?
If failures are starting to occur on a disk, but the disk has not yet failed completely, you can replace the disk. This involves detaching the failed or failing disk from its disk group, followed by replacing the failed or failing disk with a new one.
Why are hard drives also referred to as fixed drives?
The word “fixed” is used because the drives are internal or in an enclosure that’s not easily removed. Unlike a fixed disk, a removable disk such as a floppy diskette or compact disc are both easily inserted and removed from the computer. A fixed disk may also refer to the disk platter inside of a hard drive.
How to establish a striped volume in Windows?
Both disks are dynamic disks and have at least 1 gigabyte (GB) of free unallocated space on each disk for a total volume of 2 GB. In the lower-right pane of the Disk Management tool, right-click the free, unallocated volume space on either disk, and then click Create Volume. After the Create Volume Wizard starts, click Next.
How big of a disk can a striped volume take?
Capacity: The striped volume can take the whole disk or as little as 50 megabytes (MB) for each disk. Unallocated space: Any disks that you want to upgrade to a dynamic disk must contain at least 1 MB of free space at the end of the disk for the upgrade to succeed.
How does a striped volume ( RAID 0 ) work?
Summary. A striped volume (RAID 0) combines areas of free space from multiple hard disks (anywhere from 2 to 32) into one logical volume. Data that is written to a striped volume is interleaved to all disks at the same time instead of sequentially. Therefore, disk performance is the fastest on a RAID 0 volume as compared to any other type
Can a striped volume hold a boot partition?
A striped volume can’t hold the system or boot partition of a Windows Server 2003-based system. You can’t extend or mirror striped volumes. There’s no fault tolerance on a striped volume. This means that if one of the disks becomes damaged or no longer functions properly, the whole volume is lost.
