Before writing or rewriting 
Please observe the following points when you write or rewrite the data. 
■  We recommend the following manufacturers of CDR and CDRW 
media. Media quality can affect write or rewrite success rates. 
CDR:  TAIYOYUDEN CO., LTD. 
MITSUBISHI CHEMICAL CORPORATION 
RICOH Co., Ltd. 
Hitachi Maxell Ltd. 
CDRW:  MITSUBISHI CHEMICAL CORPORATION 
RICOH Co., Ltd. 
TOSHIBA has confirmed the operation of CDR and CDRW media of 
the manufacturers above. Operation of other media cannot be 
guaranteed. 
■  CDRW can generally be rewritten about 1,000 times. However, the 
actual number of rewrites is affected by the quality of the media and 
the way it is used. 
■  Be sure to connect the universal AC adaptor when you write or 
rewrite. 
■  Be sure to close all other software programs except the writing 
software. 
■  Do not run software such as a screen saver which can put a heavy 
load on the CPU. 
■  Operate the computer at full power. Do not use powersaving 
features. 
■  Do not write while virus check software is running. Wait for it to finish, 
then disable virus detection programs including any software that 
checks files automatically in the background. 
■  Do not use hard disk utilities, including those intended to enhance 
HDD access speed. They may cause unstable operation and damage 
data. 
■  Write from the computer's HDD to the CD. Do not try to write from 
shared devices such as a LAN server or any other network device.
