Data Storage Devices

Data storage devices are any piece of computer hardware used to record some sort of information. Questions about storage devices and the media on which they record information belong here.

What is hard format and soft format?

  1. hard sector formatting - sectors are separated and identified by physical notches or holes in the media that are detected optically, a counter register counts the pulses from the sensor and the number in this hardware register identifies the sector being read or written.
  2. soft sector formatting - sectors are separated and identified by coded address fields recorded on the media during formatting, as these address fields are created by the formatting software the sectors can be placed in any order (not just sequential as hard sector formatting does) around the tracks or skewed from track to track that might improve access time on a given system.
Both systems usually have a single physical notch or hole in the media used to identify the beginning of track. On a hard sector formatting system the pulse from this resets the counter register to zero. On a soft sector formatting system this pulse may or may not be used, depending on system requirements (e.g. on floppy disks when the drive could accept either single or double sided disks this hole was in different positions and was detected by a different sensor for each type of disk).

What is regular storage?

Regular storage refers to standard methods of storing data, files, or items in a way that allows for easy access and retrieval. This can include physical storage solutions like filing cabinets or shelves, as well as digital storage options such as hard drives and cloud services. Regular storage is typically characterized by its straightforward organization and accessibility, making it suitable for everyday use. It contrasts with specialized or archival storage, which may have specific requirements or purposes.

When is Auxiliary storage used?

Auxiliary storage is used for storing data that is not actively in use by the CPU but needs to be retained for future access. It is typically employed for long-term storage solutions, such as hard drives, SSDs, and external storage devices. Auxiliary storage allows for larger data capacity compared to primary storage (like RAM) and is essential for data backup, archiving, and running applications that require significant space. This type of storage is crucial for managing large datasets and ensuring data persistence beyond temporary computing sessions.

Can you play a dvd-rw on A tv?

Recordable and rewritable format (like CD-RW) promoted by Pioneer, Sharp, and Sony. Discs are playable in most DVD players, provided it is recorded in the straight Video Mode and finalized. In addition, the DVD-RW format also has the ability to perform Chase Play, which is similar to Time Slip used in the DVD-RAM format (refer to the explanation for the DVD-RAM format). However, this function is available only in what is referred to as VR mode. DVD-RW recordings made in VR mode may not be as compatible with other DVD players.

What materials are used to make floppy discs?

Floppy disks generally had the following makeup:

- A thin, plastic disk that went practically all the way to the edge of whatever casing held the disk.

- A center hole made of firmer material than the disk itself that was used to move the disk in a circle as data was written to and read. Earlier designs were plastic, while later designs were metal.

- A thin coating of iron oxide on the inner plastic disk, on one or both sides (single density or double density), which "permanently" holds a magnetic charge if a strong magnet is placed near it.

- A rigid plastic outer shell to protect the flexible inner plastic disk (the reason they were called "floppy disks").

- On later models, there was a spring loaded metal sheath over the disk's main opening, which helped prevent dust buildup.

- Also on later models, a cotton-like substance was included in the disk's interior on both sides to help remove dust as the disk was spun.

- A small plastic tab (a sliding switch) was available on some floppies; when set to a particular position, the disk's drive controller would refuse to write data to the disk, making it "read only."

So, basically, a few bits of metal, a few bits of plastic, coated with some more metal, and a bit of cotton for good measure.

What is storage temperature of FFP?

Fresh Frozen Plasma (FFP) should be stored at a temperature of -18°C (0°F) or lower to maintain its quality and efficacy. It can be kept in a freezer for up to one year. If stored at -30°C (-22°F) or lower, its shelf life may be extended beyond one year. Proper temperature monitoring is essential to ensure the plasma remains viable for transfusion.

Why should storage areas be free from clutter?

Storage areas should be free of clutter, so it is easier to find things. Removing clutter will also keep belongings clean and ensure that bugs and mice are not in the belongings.

Can you capitalize storage on machinery?

If you're refering to a new asset that has not yet been placed into use, all costs incurred to bring a fixed asset into a condition for use should be capitalized as part of the asset's total cost. If you're refering to idle machinery that is no longer in use, then storage expenses should be expensed.

Give the disadvantages and advantages for RAM?

Advantages of using RAM include being able to do more work better than waiting for everything to move from desktop to hard disk and then back again. Disadvantages are mainly to do with how often you have saved your work. If the computer stops before you have saved any work then all is lost

What is the reliablity of Storage Post?

Storage post is a very reliable and great storage company. They offer good security for low prices, and you can get good rates on storing your goods for a short term.

What are some examples of the saying the medium is the message?

I'm not sure that this is the kind of phrase that you find an opportunity to use in everyday conversation so much as it is a philosophical concept that has a very specific meaning. To learn more about it you might want to check Wikipedia's page on the book "The Medium is the Massage" (

What are the basic components and elements of input output memory storage deviceS?

Any device for storing data must have certain components. A way of getting information into the device is usually done through the network the device is connected to. The same arrangement gets information out as well. The storage is done in memory such as Random Access Memory that can 'remember' the information even if electricity is not there.

What is the function of the storage device?

They hold stuff until you need it later. Computer storage devices are machines that read stored data from storage media such as CDs.
