After having used the memory stick on a Mac and ejecting it, it does not show up at all. I have tried multiple PCs, USB slots and tha Mac it was on before but nothing happens, not even an error message.

Also, I've checked the Disk Management and it's not there either. Is there any way to fix it?

Unfortunately, that may be the case.

So many products are being made with low end components as a means to reduce costs. Any there is little or no quality control, testing, and so forth to provide any QA.

One thing you might do is get a magnifying glass and examine the metal USB plug. Look for any signs of physical damage or maybe some debris inside.

Could also try using a USB M-F extenstion cable between the memory stick and computer. Just a different port might tweak the connection enough to restore connectivity. And you can always sort of gently twist and bend the memory stick while on the end of the extension. Could reveal some connectivity problem.

Warm up the stick by setting in the sun. Some expansion might...

Do you happen to know how the memory stick originally formatted?

That said, something may have gone astray with the ejection process and the memory stick is corrupted.

May or may not be a recoverable situation with respect to any data on the memory stick.

Take a look at the following link:

http://www.howtogeek.com/252111/how-to-read-a-mac-formatted-drive-on-a-windows-pc/

There are other similar articles etc. available on various websites. Do some additional research and reading with respect to the joint use of memory sticks between Macs and Windows.

Right now the memory stick is "useless". Ideally you will find some method to recover the data - if that is a concern.

Next will be to at least get the memory stick functional by reformatting it. Will lose any remaining data but the stick will, hopefully, at least be useable again.

Thank you for your reply,

I'm not entirely sure but I think it must've been FAT32.

The memory stick is primarily used on Windows PCs but has been used frequently on Macs before without issue.

I've tried using the HFSExplorer as mentioned in the article, but that couldn't find it either, unfortunately. It's almost as if the USB is not plugged in at all.

The files themselves are more important than the memory stick, but from what I can find I'm not sure if they can be recovered. It might be as you said and the stick has just failed.

If it is an ejection issue then it just goes to show it doesn't matter how careful you are with them, they can still break!

Warm up the stick by setting in the sun. Some expansion might temporarily revive it.

And there are a number of online videos showing how to take apart a USB memory stick.

For example: https://www.youtube.com/watch?v=9-J6yTqrr9s

Probably nothing repairable but you have nothing to lose.

I'll try those methods and see if anything helps, not expecting much though.

Luckily I found a fairly recent back up for most of the files anyway, still frustrating and as you say, seems like there was very little QA involved in the design process.

Thanks for your advice!
