[. . . ] This mode allows for the most control of the recording process for audio CDs because the gap between tracks can be set and the maximum capacity of the CD can be utilized. Multisession (MiS) - A CD writing process where data is added incrementally to a CD in more than one recording session. This mode uses TAO, allowing you to add data during several sessions. With this mode, though, every time a session is added, nearly 15MB of information is used to create data about the session. Packet Writing (PW) - A CD writing process that is very useful for data backup, but cannot be used to write audio CDs. Buffer underrun* is impossible in this mode, because the data is written in "packets" of a few KBs. Session at Once (SAO) - A CD writing process which is similar to DAO, where all of the information is written in one session, but SAO allows for the ability to begin another session and record at a later time. This mode allows for greater control of the recording process than MiS, PW or TAO, and more disc space can be utilized because there is no need for gaps between tracks. Track at Once (TAO)- A CD writing process where data is added one track at a time, and the data can be added at a later time. The CD being written to, though, can only be read in the CD rewritable drive that is recording it until the disc is finalized (meaning that no more data can be added). There is also a gap of 2 seconds added between tracks, which will be heard as noise in some audio players. Tech Note: *Buffer Underrun - The recording of a CD is a system-intensive application, and the rewritable drive needs a constant stream of data. A buffer underrun occurs when the stream of data to the rewritable drive is not fast enough to keep the rewritable drive's buffer full, causing the an error in the recording process. If this problem occurs often, turn down the recording speed and consult section 4. 1. 3 Data Transfers. LaCie Slim Combo CD-RW Drive User's Manual Helpful Information page 16 4. Advice For Optimizing USB 2. 0 Connections The following technical information relates to your LaCie CD-RW Drive and gives some practical advice: 4. 1. 1 What is USB 2. 0? The new USB 2. 0 standard provides higher bandwidth for high-speed peripherals such as external hard drives, high-speed scanners and CD-RW drives. USB 2. 0 delivers transfer rates up to 480Mb/s, while conveniently maintaining backward compatibility with USB 1. 1 devices. USB 2. 0 can still be used to connect lower-speed USB 1. 1 ports and devices like digital cameras, scanners, modems, keyboards, mice, joysticks and printers. In the USB 2. 0 system, existing USB peripherals do not have to be upgraded, and lower-speed devices will not require additional performance, instead operating as USB 1. 1 devices. USB 2. 0 Logo USB 1. 1 Logo USB Cables and Connectors Your LaCie drive is shipped with a USB 2. 0-certified USB cable, to ensure maximum data transfer performance when connected to a USB 2. 0 port. The cable will also work when connected to a USB 1. 1 port, but drive performance will be limited to USB 1. 1 transfer rates. There are also different types of USB connections, such as the mini-cable and device end. Make sure that you have the correct type of connection on computer. [. . . ] If you buy a hub, make sure that it supports per-port switching. This function prevents the entire chain of peripherals from freezing up if one of them is not working properly or is down. Important Note: Avoid using USB connectors found on certain peripherals such as keyboards. These are passive (or pass-through) connectors that lead to power loss and unstable operation. [. . . ]
