I have a mugful of SanDisk fit USB drives (4 to 64 GB sizes, multiple of each) with no problem on the hoard…
However, recently I bought three 128GB UltraFit from Amazon to find ALL of them:
1) They get extremely hot on R/W on Max OS X10.
2) They get ‘ejected’ or disconnected by Mac OS X 10 after a few minutes of use.
What’s SanDisk view or policy on the defective products?
