5.3 - Troubleshooting Storage Devices Flashcards
What does a ‘cannot read from the source disk’ message indicate?
A problem reading or writing information to the storage drive, potentially a failed drive.
What is the ‘click of death’ in hard drives?
A loud clicking noise indicating the drive may be failing or already failed.
What should you do first when troubleshooting storage problems?
Make a backup of all critical data on the drive.
What might you check if the storage drive is failing or performing slowly?
Check for loose or damaged cables and system overheating.
What can cause a system to not boot and show ‘boot device not found’?
Incorrect BIOS boot order, disconnected cables, or a malfunctioning drive.
What to do if the system displays ‘operating system not found’?
Check physical cable connections and BIOS boot sequence.
What to check if a new storage drive isn’t recognized?
Ensure proper physical installation and try different SATA interfaces.
What is RAID and what does it do?
RAID stands for Redundant Array of Independent Disks, used to combine drives to maintain uptime and availability of data.
What is RAID 0 and its risk?
RAID 0 requires two or more drives; a single drive failure results in data loss.
What is RAID 1 and its benefit?
RAID 1 requires at least two drives; the array continues to work as long as one drive is operational.
What is RAID 5 and its requirement?
RAID 5 requires three or more drives; all but one drive must be operational.
What is RAID 10?
RAID 10 (RAID 1+0) requires four or more drives and can lose all but one drive from each mirror set.
What does SMART stand for?
Self-Monitoring, Analysis, and Reporting Technology.
What does SMART information provide?
Details on drive health and performance metrics such as spin-up time and error rates.
What is IOPS and why is it important?
Input/Output Operations Per Second; a measure of drive performance in reading and writing data.
