It seems the 1.5 ac adaptor has ceased working to my wdbaau001hbk-01 hdd that I use to download programmes from my tv. I have a spare adaptor that is 1.0a and wondering if I can use it or any suggestions welcome please.🤔

Whats the output voltage on both adapters? You could give it a go if it's similar, but my guess is 1a might not have enough guts to start the hdd spinning.

You could give it a try but you may fry the power adapter as it does need the 18w / 1.5a according to the specs. Perhaps if you don't let it run for hours you will be fine, but don't let it run unattended.

I wouldn't go smaller, you might end up with funky things happening, could even get some data loss.

You need to look at:
Output type (AC / DC) - MUST be the same.
Output voltage (V) - MUST be the same.
Output current (A / I) - Should be the same or more than the old one.
Plug polarity( _-(o-_ ) - MUST be the same.

Any of the above items can result in destruction of your device if they are wrong.

A proper adapter will current limit and should be fine except the drive will not work, but there are many DC adapters out there which will cook up instead.

And its impossible to tell without putting a load on it and seeing what happens. I have some mid price range USB chargers that are rated to 2.4 + 1 amps - so 3.4 in total but you can pull 8 amps from either socket on them before they finally drop the voltage down. They then let out the magic smoke after about 4 mins.

Thanks guys, I get the feeling it's the HDD after all. Plugged in the other adaptor and not even a glimmer of light. It's a pretty old unit and probably past it's by date.

(Bit like me really.......82 and told I'm in the current vulnerable zone!! 😂😂)

Take care and stay safe.......

Don't shoot me for this but don't these devices (and the specifications) usually have a generous safety margin built in? I would think you could probably get away with it but of course it depends on the quality of the 1 amp adapter.

If it was me I would give it a go otherwise i would cut off the wall ward and hard wire the lead into my computer 12V rail.

You could potentially remove the HDD and put it in the computer (assuming you have spare power and sata for it)

from memory, those WD enclosures are a bit of a pain to get into though.

Some models have a different drive interface to make this difficult. Made to work only with specific enclosure. Depends on model.
