Sony MZ-M200 Hi-MD Music Transfer Version 1 for Mac (User Manual) Operating Instructions Manual page 65

Symptom
You cannot transfer audio data
from your computer that will fill
up the remaining recording time
on the disc.
The disc size displayed on the
computer is not the same as the
disc size printed on the disc.
You cannot operate the recorder.
The lid does not open.
While recording
Symptom
The remaining recording time
appears as "R 00:00" and recording
cannot be done, even though 2.0
MB of free space is displayed.
The recorder always creates a new
group when recording.
The first few seconds of a track
cannot be recorded.
A new group cannot be created.
Case and/or corrective action
 Due to the limitations of the system, the audio data is recorded
in several-second steps. Therefore, when you record many short
tracks, the total recording time increases but does not tally with
the remaining recording time.
 The difference is due to the use of the binary system to indicate
the disc size on the computer and the decimal system to express
the disc size on the disc (  page 30) and other recording media.
 You cannot operate the recorder while the recorder is connected to
the computer.
 It happens if you disconnect the USB cable in the middle of a data
transfer, recording, or editing operation on the computer, but while
the rechargeable battery is missing from the recorder or is drained.
Reconnect the USB cable or insert a fully charged rechargeable
battery into the recorder, and then press  · CANCEL.
Case and/or corrective action
 This is a system limitation. 2.0 MB is the capacity of the reserve
domain.
 The group recording ("Group REC") is set to "On". (You cannot
overwrite tracks.) Set the group recording setting to "Off" ( 
page 51).
 If you start recording before the operation mode appears and the
operation lamp disappears in the display, data will not be recorded
to the first few seconds of the first track. Wait until the operation
mode appears and the operation lamp disappears before you start
recording.
 This occurs due to the MiniDisc system limitation (MD mode
only). When the total number of characters used on a disc (for
track names, artist names, album names, group names and disc
name) is more than about 1,700, it becomes impossible to create a
new group.
