M1 Mac freezes when transferring data to Kingston DataTraveler Max

For some reason it seems to have fixed itself. I'm quite baffled.

I've been keeping on trying: Copying files until the transfer stalls. Rebooting de computer. Reformatting the flashdrive. And repeating. Each time using a different drive name, to keep things interesting.

And with my last attempt, it just kept going. As I was watching the transfers go by. Once in a while it would freeze for a second or so. But that's quite normal.

On another note: while typing this message, a reply came in from Kingston. They have no knowledge of this being a problem. And suggest me getting in contact with Apple (through a provided link), as it must be an issue on that end. And evidently the solution must come from that end.

To conclude, as the bulk of my data is now on the drive. I don't foresee any issues when doing an incremental update of the files.

Thanks to everyone who made effort in helping getting this drive operational.

Hello,

first of all: thank you for this extensive and easy-to-follow reply.

As a rule I format any drive I buy. I've even done so a second time in my trials. As a conquence, the suggestion steps only fixed minor issues.

As to continue my investigation I now have formatted the drive to exFAT in stead of Mac OS Journaled. But alas this made things even worse. I was no able to copy anything.

Now I've tried formatting the container (to Mac OS Journaled) in stead of just the volume. By resetting the volume once again, I was once more able to transfer about 10-12 gigs before the phenomenon reappeared.

It feels like there's a buffer somewhere on the Mac that fills up and then freezes the transfer once it needs to offload onto the device.

with kind regards

Hello,

at the moment the manufacturer is requesting additional information. When I do get a reply, I will keep this discussion updated.

As to copying smaller set of files. I have been successful in copying some files. They appear when checking with my other Mac.

Problem is that there is a lot of margin when the 'freeze' occurs. I've seen stalling at 100 MB but at 10,90 GB as well. Which makes it hard to decide how big the chunk of files should be, to transfer successfully.

Also very unpractical to use this drive as an external backup for about 300 GB of files.

Yes,

i've erased the drive at the highest level. It was Apple-Partition schemed before. As per your request I've changed it to GUID-partition.

Unfortunately this has not solved the issue.
