Chapter5 Flashcards
What do you need to keep in mind when purchasing a SATA hard drive?
STA standards for the drive and motherboard need to match
What to consider when selecting a hard drive?
- Technology
- Form factor
- Capacity
- Data transfer rate as determined by the drive interface
- The spindle speed for magnetic drives
What are the two SATA power connectors?
1.Choose only one power connector to be used
2. Never install two power cords to the drive at the same time
What are the steps to install a SATA drive
Step 1: Backup important data to other media and verify that you can access the data on that Media
Step 2: How is your system configured?
Is everything working properly?
Step 3: Read all installation instructions first. Visualize all the steps in the installation . Protect against ESD and avoid working on carpet
Step 4: Shut down the computer,unplug it ,and press the power button to drain residual power. Decide which bay will hold the drive. Slide the drive in the bay and secure it (use two screws on both sides). Use the correct motherboard SATA connector. Connect a 15 pin SATA or 4 pin molex power connector from the power supply to the drive . Check all connections and power up the system. Verify that the drive is recognized correctly using BIOS/UEFI setup.
How to install a drive in a removable Bay?
-Unplug the cage fan from its power source. -Turn the handle on each locking device counterclockwise to remove it.
- Slide the bay into the front and out of the case - Insert the hard drive in the bay and use two screws on each side to anchor the drive in the bay .
- Slide the Bay in back into the case
- Reinstall the locking pins.
- Plug in the cage fan power cord
How to install an m.2 SSD card
- Measure the length of the card and decide which screw hole for the m.2 slot the card requires
- Slide the card straight into the slot, but not from an upward angle.
- Install the one screw in the standoff to secure the card to the motherboard .
- Start the system go into the BIOS/UEFI setup, and make sure the m.2 card is recognized by the system.
General steps to replace a hard drive
-Power down the system; remove peripherals; and remove the battery pack
-Remove a screw that holds the drive cover in place.
- Remove the plastic cover from the drive and lift and remove the hard drive.
- Insert the new drive in the bay ,replaced the cover and screw ,then power up the system. - BIOS/UEFI should recognize the new drive and search for an OS
- If drive is new, boot from the windows setup or recovery DVD or USB flash drive and install the OS.
What is RAID
A technology that configures two or more drives to work together as an array of drives
Why use RAID
- Improve performance by writing data to two or more hard so a single drivers not excessively used
-To improve fault tolerance by writing to copies of it ,each to a different hard drive.
Types of RAID
- Spanning: uses two hard drives to hold a single Windows volume .
When one drive is full, data is written to the second drive - RAID 0 : writes to physical disks evenly across all disks so that no one disk receives all activity
- RAID 1: duplicates data on one drive to another drive and is used for fault tolerance.
- RAID 5: stripes data across drives and uses parity checking and data is not duplicated
- RAID 10: is a combination of RAID 1 and RAID 0 and takes at least 4 disks and data is mirrored across pairs disks
How to implement hardware RAID
‘Hardware RAID can be set up by using a RAID-enabled motherboard that is managed in BIOS/UEFI setup or a RAID controller card.
- For best RAID performance all hard drives in any array should be identical in brand, size ,speed and other features
- If Windows is to be installed on a hard drive must be implemented before Windows is installed.
General directions to install a RAID 5 array using three matching SATA drives
-Install the drives in the computer case and connect each drive to motherboard
- Boot the system and enter BIOS/UEFI setup to verify the drives are recognized ,select the option to configure SATA and select RAID.
- When the system reboots, enter BIOS/UEFI ,on the Advanced page ,select Intel Rapid storage technology and then select Create RAID Volume. - Under RAID level, select RAID 5( parity )and strip size value
- Enter size of the volume
- Select Create volume to complete the RAID configuration
Troubleshooting hard drives
Problems caused by hard drives
-Hard drive subsystem
- File system on the drive
- Files required by windows when it begins with load
Overall performance of the system depends on the following
Individual performance of the processor, motherboard ,memory and hard drive
What to use to diagnose hard drive performance
Hard drive speed test utility program such as DISKSPD
You can also use the windows different and optimization tool optimize a hard drive
