New mac corrupting external hard drives and USBs
Hi,
So last week I finally got my brand new mac mini M2! However, I've had quite a few issues with external hard drives and usbs with it since.
The first issue occured on Friday where I had my external hard drive plugged in, it was working perfectly then it just ejected itself and would not show up anymore. I tried it across my macbook air, my old windows and PC and my mum's windows PC and it just wouldn't show up. Being less than a year old, I took it back as it must have been faulty and got a new hard drive. It showed up fine on my mac and I formatted it on my mac so it could go between mac and windows without issue. Backed up my windows pc (again) and when I plugged it back into my mac, it would not mount, no idea why, the formatting hadn't changed. I thought reformatting it would sort the issue but nothing seemed to get it to mount again. Gave up with this hard drive and returned it.
The problem has then come that I've transferred some files to my usb (that works across both mac and windows) from my new mac and then the files are showing up as corrupt on my mum's windows PC. Tried with her external (pre-formatted with exfat), it ran fine on my mac but then started showing up with errors on her windows PC.
What is going on, why is this happening? I'm now worried that something is very wrong with my mac and has corrupted my mum's external hard drive which is only a couple of months old.
