Check the specifications that came with your computer to confirm that this optical drive is capable of reading this type of CD or DVD. 4. If the CD/DVD cannot be read, replace it with a known good CD/DVD such as one that was shipped with the computer. 5. If the known good CD cannot be read, visually check the operating side of the CD/DVD for defects. Problem: The capacity of the hard disk, as indicated by the system, is less than the nominal capacity. Troubleshooting and problem resolution: For computers equipped with the OneKey Recovery feature, the system recovery feature needs to occupy some hard disk space. This may account for the apparent hard disk capacity deficit. Further Technical Explanation: The nominal capacity of the hard disk is expressed in the decimal system as 1000 bytes. But the actual hard disk capacity is expressed in the binary system as 1024 bytes (For example, the nominal capacity 1G is 1000M, while the actual capacity 1G is 1024M). The capacity of the hard disk shown in Windows can be calculated according to the calculations in the following example: The nominal capacity of the hard disk is 40G, while its actual capacity should be: 40 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 37G. If the Service partition of 3G - 3 x 1000 x 1000 x 1000/(1024 x 1024 x 1024) = 2. 79G is subtracted, the capacity of the hard disk shown in the system can be obtained. The capacity of the hard disk as calculated using this method may be slightly different from the actual capacity due to the rounding of totals. Special considerations for troubleshooting Windows Record the following information as it may be useful later when troubleshooting system problems: The drivers for this computer model only support the Windows 8. 1 system.
