Hard Disk Problems
The hard disk drive does not work or is not recognizable -
If you had just performed a hard disk upgrade, make sure the hard
drive connector is not loose and the hard disk drive is also correctly
seated. Remove it and reinsert it firmly, and restart your PC.
The new HDD may need to be partitioned and reformatted. O/S and
drivers will need to be re-installed as well.
Check the hard disk indicator LED. When you access a file, the LED
lamp should light up momentarily.
The new HDD may be defective or is not compatible.
If your computer has been subjected to static electricity or physical
shock, you may have damaged the disk drive.
The hard drive is making abnormal whining noises -
You should back up your files as soon as possible.
Make sure the source of noise is indeed from the hard drive and not
the fan or other devices.
The hard disk drive has reached its capacity -
Run Disk Cleanup utility in Windows. [Start > All Programs >
Accessories > System Tools > Disk Cleanup] The system will prompt
you for what to do.
Archive files or programs that you had no longer used by moving them
to an alternative storage medium (floppy disk, optical record-able
disk, etc.) or uninstall programs that no longer use.
Many browsers store files in the hard drive as a cache to speed up the
performance. Check the program’s Online Help for instructions on
decreasing the cache size or on removing temporary Internet files.
Empty the Recycle Bin to create more disk space. When you delete
files, Windows saves them to the Recycle Bin.
The hard disk takes longer to read a file -
If you have been using the drive for a period, the files may be
fragmented. Go to [Start > Programs > Accessories > System Tools >
Disk Defragmenter] to perform a disk defragmentation. This operation
may take a while.
Interrupt requests or problems with other hardware devices may have
occupied the CPU and therefore slows down the system
performance.
The files are corrupted -
Run the Error-checking utility in Windows to check the HDD. Double-
click My Computer. Right-click C: and select Properties. Click Check
Now in Error-checking in Tools.
