I occasionally have my usb-c ssd drop out spontaneously when I connect it to my Mac. it drops out randomly, very often during copying, sometimes in the middle of copying.
how can I solve this problem? any ideas?
MacBook Pro (M1, 2020)
What model of SSD do you have? What file system is the disk formatted in? For Mac, it's optimal to use APFS instead of exFAT/FAT32. Can you check the SMART status of this SSD?
Direct connection to USB or through a dock? Have you tried connecting to another port? What is the SSD temperature during copying?
exFAT has been shown to be an issue. If not using for a Windows PC then be sure to format APFS
It's not the cable, I've tried different ones. The SSD is an M2 NVME that I put into a case with a USB-C connection. I tried another case and had the same issue. With the same case but a different SSD, there are no problems. I'm pretty sure the issue is with the SSD itself.
Are you sure it isn't the enclosure. I have a new Samsung T7 shield which is great and really fast. But it has one fatal flaw. The USB port is very loose. Even the slightest movement will cause the port to lose connection.
Try another cable. If the SSD is in your own enclosure that also could be an issue with connection integrity. If so try another enclosure.
I use exFAT, SMART is ok
Format to APFS and test.
