If necessary, reinsert the CD-ROM into the drive. • Check to make sure that the inserted CD-ROM is recognized by the CD-ROM drive. For example, a CDROM drive will not recognize a DVD-ROM. Insert one of the CD-ROMs from your computer package to confirm if the CD-ROM drive can read this CD-ROM. • Check to make sure that the inserted CD-ROM does not have any defects. If defects are found, remove the CD-ROM and insert one of the CD-ROMs from your computer package to confirm if the CD-ROM drive can read this CD-ROM. 2.The hard disk capacity that is shown in the system is smaller than the marked capacity. The OneKey Recovery function occupies some room in the hard disk, which is not visible in the operation system and some partition tools such as FDISK. So it is normal that the hard disk you can use is smaller than the marked capacity. The marked capacity of hard disk takes 1,000 as the calculation unit, while the actual capacity takes 1,024. For instance, the marked capacity of 1G equals 1,000M, while the actual capacity of 1G equals 1,024M. You can take the following example to calculate the actual capacity that is shown in Windows.
