Anyone else experienced this? When the drive is in stand-by (blue light) it keeps small, but audible high-pitch whine or buzz, which stops as soon as the drive starts up. It’s quite annoying because i sleep in the same room and i can eliminate all other sound by turning the devices off. I would like to know if anyone else has noticed this and is it a “feature” or is my unit faulty. I live in Europe (230v/50hz) and I dont know if it has any meaning but i think it’s worth mentioning because of the difference in electricity distribution model.
Mine makes a short high pitched buzzing sound whenever it wakes up from sleep. Otherwise it’s very silent. I think mine is the spin-up sound but maybe it’s coming from the power adapter. None of my internal or external drives make a sound like that when they spin-up.
It would be nice to know what is the official reply on this. Also, I think you should try to observe your unit carefully because the noise is very, very quiet but nevertheless really annoying, I can hear it while im working at my desk, on my left side I have only my Macbook pro running and it is quiet.
I would contact our support group and talk to them about this. This is not normal. I have mine on my desk next to me and can barely hear it even if I put my ear up to the device.
What about the short (1 sec) high pitch buzzing sound I am getting whenever the unit wakes up from sleep? Is that normal? Otherwise the unit is very quiet both idling and under load. Thanks,
