The player reserves a small portion of storage for its internal software, and manufacturers label capacity using decimal units while computers use binary units, causing the discrepancy.
Remove the battery, then re‑insert it and power the device on again, or check that the battery has sufficient charge.
Early versions of Windows 2000 may have this issue; installing the Windows 2000 patch from the supplied CD resolves it.
If the "high‑quality" recording mode is selected, the file is saved as WAV; the "long‑time" recording mode saves files in ACT format.
