Sony PCG-R505DC - Manual (Page 136)

Saving to your hard disk drive
In order to improve the performance of your computer's DVgate motion software, the hard disk drive on your computer
has been formatted with two partitions, C and D. The C partition holds 40 percent and the D partition holds 60 percent of
the entire drive capacity. DVgate software saves files to the D partition. This prevents large video capture from consuming
the available space on your C partition. To maintain optimum performance of DVgate, you should defragment or format the
D partition regularly.
To defragment a partition
1. Back up all files you want to save.
2. From the Start menu on the Windows ® taskbar, point to All Programs, Accessories, System Tools, and then
click Disk Defragmenter. The Disk Defragmenter dialog box appears.
3. Select the drive you want to defragment from the list, and click Defragment. See the Windows ® operating system
Help guide for more information on defragmenting.
