How the working of floppy disk drive differ from hard disk drive?

Does DNA store its information more efficiently or less efficiently than a computer?

The data storage density is much higher in DNA than in any electronic or magnetic memory available on computers today.

For example every human cell contains 6,469.66 million basepairs (1.617415 GB) in the DNA inside its nucleus. This is similar to one RAM module on a modern computer.

Remove the write protection or use another disk?

There are several possibilities:

  • Check if there is a physical write protect switch on the side of the flash drive. If there is set it to the opposite position it is in now.
  • Your operating system may be set to prevent writing to USB drives. Google how to change this setting for the appropriate operating system.
  • Your flash drive needs a low level format. Check with your manufacturer's web site for details.
  • Your drive is toast and should be replaced.

What does the disk optimization process do?

Ø Disk optimization process collects file fragments and puts them back together. Whenever the files are changed and saved for frequent times, they become fragmented and the volume is filled with different parts of a single file stored in different locations on a volume, here the optimization process collects all those fragmented files into a single one sunil khadka aicl college

Why does the fan on your mac book makes a semi loud clicking or mooing noise when you try and play a DVD or CD?

Without seeing the machine in person, its impossible for me to tell, but if its only doing this when you play DVDs or CDs then its probably the DVD drive that's making the noise.

Optical drives spin at very high speeds when theyre reading & writing, if the disk or the moving parts of the drive are out of balance, it can make the drive vibrate & it can be quite noisy.

Note that it is not uncommon for cheaper media (like stuff you find in the $5 bin at walmart) to do this, but if all discs are doing this, youll need to replace your DVD drive.

If that's the case, contact apple & see if theyre willing to do a warranty replacement, the worst they can do is say no.

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.
