Great thread. This is the only place that explains the musical tones eminating from my 120gb maxtor drive. No boot because the drive gave a boot error.
Fortunately after taking the cover off and restarting the computer three or four times to locate the source of the sound, the drive started and the computer ran normally. Sounds stopped when the drive operated.
Thanks for the effort to document the problem.
Time to contact Maxtor tech support (no mention of the problem on their site)
