A DASD, or Direct Access Storage Disk, is a type of storage device that is connected directly to a user’s computer rather than being connected to the network. Because many types of storage device connect directly to a user’s computer, the term “DASD” may apply to a variety of different devices; however, a DASD is …
PATA is an abbreviation for Parallel Advanced Technology Attachment. It is a regular interface that is used within PCs to connect all kinds of storage devices like hard disks, CD or DVD drives and solid state disks to the motherboard. The PATA interface connector is made up of thirty four pins and is connected to …
USB flash drives provide users with an enormous level of satisfaction and accessibility due to their massive storage capacities, low cost, and small size. USB flash drives serve an important role in our society and have a precedence over other means of data transportation. Where as computers used to have floppy disk drives as well …
Secure Digital (SD) memory cards are very simple to format. There are 3 main options to format the SD cards to the format needed. To successfully format an SD card, the write protection lock on the side of the card must be in the “unlock” position. SD mini and micro SD cards must be used …
Mirroring is the automated process of writing data to two drives simultaneously. Mirroring is used to provide redundancy, backup, multiple concurrent accesses and uninterrupted accessibility. If one drive fails, the redundant drive will continue to store the data and provide access to it. The failed drive can then be replaced and the drive set can …
eSATA stands for External Serial Advanced Technology Attachment. It is meant to be an external interface for SATA technologies. SATA or Serial ATA (Advanced Technology Attachment) is the next generation of drive interfaces, its predecessor being the Parallel ATA (PATA). PATA Anyone who has opened up their computer must have noticed the flat, 40-wire parallel …
SCSI (Small Computer System Interface) is a set of ANSI standards for connecting devices to computer systems. The vast majority of SCSI devices are data storage devices. Standard SCSI is a parallel technology, but many serial SCSI variants exist, including FireWire and Fibre Channel. SCSI is generally considered a higher-end alternative to IDE (Integrated Drive …
The MBR is the Master Boot Record. The MBR is a small program which runs whenever a computer boots up. The MBR is stored in the first sector of the boot disk. The boot disk may be a hard drive, a floppy drive, or even a CD or DVD drive. The Task of the MBR …
File and disk fragmentation usually causes problems in large networked companies where many people simultaneously save, retrieve and delete their work on a company’s servers. In an ideal scenario, people will be ‘lining up’ to use the company’s servers, allowing data management (especially storage and retrieval) to proceed in an orderly, logical, and sequential manner. …
ATAPI, Advanced Technology Attachment with Packet Interface is the standard interface (type of connection) used to connect hard drives, CD-ROM drives and other components like RAM, motherboard inside the CPUs of personal computers. It is the standard developed by Western Digital and maintained by the International Committee for Information Technology Standards (also known as the …
