Hi there,
my WD Passbook is making this strange noise lately. Its still working but im afraid it won’t be for long anymore. I’ve changed the connected Mac/PC and the USB wire. WD Drive Utilities says everything is fine.
Any ideas?
a beeping sound usually indicates the hard drive is not getting enough power.
my WD Passports will starting beeping if i plug too many of them into a Non Powered USB Hub (plugging them into a Powered USB Hub and they stop beeping)
Have you got any other portable USB Hard drives you can test to see if it’s a power issue and if they do the same ?
I’m not sure what to advise except … backup your data NOW in case it does fail (which it probably will if there’s a problem.)
Thanks for the advice,
I’ve came across this before that’s why I’ve tried all USB ports on my MacBook und my PC (front an back) - still the same issue. I’ll try an powered USB port, if I find one
