Drive is only 11% full (320GB version). It’s formatted NTFS. I’ve only used it on a Mac.
I’m wondering if it’s possible for these to overheat? It felt very hot when it started malfunctioning (supposed to work up to 95F, but don’t think it was THAT hot). However, other saved projects continue to work.
I successfully transferred about 15 min prior to the start of the problem.
