Study Notes
- Some computer issues with storage drives may be caused by overheating or overloading the power supply.
- If new hardware has been added, check if the power supply can handle the additional voltage requirements.
- Hardware diagnostics can be run by the drive manufacturer to check for any internal errors.
- During startup, various messages may appear indicating issues with drive recognition or boot devices.
- Operating system not found messages may indicate that the drive has been physically disconnected or that the operating system is corrupt.
- Checking the physical configuration of the storage drive, such as properly attaching cables to the motherboard, is the first step in troubleshooting.
- The BIOS maintains a list of priorities for boot devices. If an operating system is not found, the BIOS moves on to the next one in line.
- USB interfaces may cause boot issues if a USB drive is left connected and set as a priority in the BIOS.
- Data and power cables should be checked if a new storage drive is not recognized.
- Trying different SATA interfaces may help identify which one is operational.
- Hard drives are mechanical systems and will eventually fail. Constant backups are necessary to prevent data loss.
- SSDs can also fail and may only allow data to be read but not written.
- RAID arrays are used to combine drives and maintain data availability.
- The text mentions a RAID exception detected and offers the option of starting the Dell configuration utility to investigate.
- The text mentions RAID types, such as RAID 0, RAID 1, RAID 5, and RAID 10, each with different requirements and levels of redundancy.
- A RAID array requires multiple drives, and a single drive failure can result in different levels of data loss depending on the RAID type used.
