14. Troubleshooting Disk Performance
It’s not always the disk itself...
Network not disks?
Background processes?
RAID cache tuning?
Low disk space?
Protocol / software problem?
Drive / controller firmware?
Paging?
Malware / faulty process?

Troubleshoot storage and volume availability problems
What two options does Windows have for making a volume available? Mapping to a drive letter or mounting the volume within a folder.
A user reports that they cannot access a shared volume mounted on a Windows server. What should you do? Use the Disk Management utility to investigate the status of the volume.
True or false? The Disk Management tool lets you see which volumes are low on free space. True - free space and utilization is shown in the top panel.
What Windows utility would you use to identify bad sectors? Check Disk (chkdsk /r)
If you have created a partition on a removable drive in Linux, what command would you use to make it available as a volume? The mount command.
With what type of disk or interface would "Improper termination" be an issue? Parallel SCSI.
What command could you use to verify the partition structure of a disk in Linux? fdisk.
What are the two main risks from cache failure on a RAID controller? Slow performance and data corruption.
