Trouble Shooting Storage Devices Flashcards
What does “cannot read from source disk” denote?
a serious read/write failure. its an error that occurs when a computer or software program is encountering difficulties when trying to access or read data from a specific disk or storage device.
what can cause the “cannot read from source disk” error?
disk or file corruption, permission issues, disk drive failure, file system errors, data transfer issues, insufficient disk space, hardware malfunction, disk encryption
what steps can you take with the “cannot read from disk” error?
- check the physical connections of the storage device.
- Run risk diagnostic and repair tools
- Ensure you have the necessary permissions to access the disk.
- Make sure there is sufficent disk space
- If applicable, decrypt the disk or file
what is the click of death?
a term for the distinctive clicking sound that emanates from a malfunctioning or failing HDD.
what should you do when you hear the click of death?
immediately back up all data. replace harddrive and use professional recovery service to recover data.
what is SMART?
Self Monitoring Analysis and Reporting Technology. a feature on most modern hard drives and can provide early warnings of potential issues, allowing users to back up their data before a catastrophic failure occurs.
what does the error “drive not recognized mean?”
typically indicates that a computer device is unable to detect or identify a connected storage drive.
what can cause the error “drive not recognized”
- physical connection issues
- drive power issues
- driver problems
- drive letter conflict
- file system or partition issues
- drive failure
- BIOS/UEFI setting
- External drive enclosure / adapter issues
what does the error “operating system not found” mean?
this appears when a computer or device is unable to locate a valid operating system to boot. It ususally occurs during the startup process.
what causes the “operating system not found” error?
- corrupted or missing boot file
- misconfigured BIOS/UEFI
- Disconnected or faulty harddrive
- corrupted operating system
- bootloader issues
- removed or replaced hardrive
- external drive media connected
how do you resolve the error “operating system not found”
- check the BIOS/UEFI settings
- Inspect hardware connections
- Repair or reinstall Operating System
- remove any external media
- Data recovery
- remove the SATA or M.2 drive to see if it works in another system
what is RAID?
Redundant Array of Independant Disks. a technology used in data storage to improve performance, reliability and redundancy by combining multiple physical disk drives into a single logical unit.
what parts of the computer system are used when retrieving or storing data?
memory access, communication across the bus, spinning drive access, writing or reading the data to a storage device
what is spinning drive access?
refers to the process by which data is read from or written to a traditional mechanical hard disk.
what is one way to measure the overall performance of a storage device?
by measuring the IOPS (input/output per second). IOPS is a metric used to measure the performance and speed of storage devices such as HDDs and SSD.
