When data is written to storage devices, the process involves several key steps:

1. Data Request: The computer receives a command to save data, typically from a user or an application.
2. Data Conversion: The data is converted into a binary format (0s and 1s) that the storage device can understand.
3. Controller Interaction: The storage device’s controller, which acts as a manager, organizes and oversees the data transfer process.
4. Seek Operation: The storage device locates the specific position where the data will be written.
   • Hard Drives: The read/write head moves to the correct location on the spinning disk platter.
   • Solid-State Drives (SSDs): Electrical circuits identify the precise memory cells for data storage.
5. Writing Data:
   • Hard Drives: Data is written by magnetizing specific areas on the disk platter.
   • SSDs: Data is written by changing the electrical charge in memory cells.
6. Error Checking: The device verifies that the data has been written correctly to prevent corruption.
7. Confirmation: The device sends an acknowledgment to the computer, confirming successful data storage.
8. File System Update: The file system updates its records to reflect the new data’s location and metadata.

This sequence ensures data is accurately stored and easily retrievable from the device.
