Computer Drives and Storage

Using Redundant Array of Independent Disks technology can improve the performance of your storage, offering both speed and reliability benefits. Monitoring the speed of your RAID setup is important, enabling you to see whether your storage is underperforming and helping you to identify when it is time for an upgrade. RAID speeds are measured using benchmarking software, which test how long it takes the RAID array to perform a series of tasks.

A computer can block your ability to create new folders within Windows File Explorer because the user account does not have permission to write to a specific drive or folder location. File corruption, a virus or malware may have damaged vital Windows files that control the "Create New Folder" functionality as well. You can restore your ability to create new folders by granting the user account the correct permissions or by fixing the damaged Windows files.

Mac computers include a disk-transfer feature, called Target Disk Mode, that turns your computer into an external FireWire drive. This setting is only compatible with FireWire, so you may need to purchase an adapter if your PC doesn't have a FireWire port. When connected to a Macbook Pro in Target Disk Mode, Windows recognizes the external drive but requires additional software to read the HFS+ partition and exchange files. Disk-reading software opens your Mac drive in a browser window from which you can copy files to your PC.

A physical disk signature is a unique hexadecimal identification string of characters assigned to a computer storage device. The term "physical disk" refers to a hard drive. A computer or computer-like device can use the physical disk signature to tell different storage devices apart and recognize storage devices that have been attached to the system previously. If a computer has two storage devices with matching physical disk signatures or a storage device with an altered physical disk signature, it may encounter problems.

The Small Computer Serial Interface once formed the principal connection protocol used in Apple's Macintosh computers and on drive arrays. SCSI remains a viable choice for some specialized storage implementations, but it lacks the drive capacities, inexpensive pricing, simple connectivity and wide acceptance to make it competitive with SATA on a broad scale. SCSI drives require special attention to their preparation, cabling and formatting to assure proper function when you put them in service.
