Q: Can I use hard drive compression software? It is not recommended to use hard drive compression software when CD-ReWriter is installed. CD-R and CD-RW writing program may check free space to estimate needed space. However, due to the hard drive compression software's compression ratio may vary from time to time. The actual free space available may not be enough for disc copying. Q: To maintain optimal writing performance Regularly run disc de-fragmentation and scanning programs on your hard drive (please refer to your Windows manual for detailed information). Doing this improves the access time to the hard drive, and thus ensures writing in higher performance. Finally, these are only GENERAL rules and not necessary to apply to any combination of CD-ROM drives, HDD and motherboards. A few trials on different configurations before recording are recommended. Also, try out different CD-R media before you proceed to make volumes duplication as you may figure out which brand of CD-R media originates smoother recording and easier access. As long as you find the best CD recording way, stick to it. Have a nice recording time. User's Manual E-13
