@sifyfanI have never used ntfs, and I never will use it. FAT32 is sufficient for my needs. And yes, I would never rely on any hardisk, whether it be internal or external or flash drive. @blr_pgood explanation...but its logical...I guess logical for software people hehehe 😀 Also I did not have to go for a replacement, it works fine. You wrote about backing up to a drive under warranty...but what if that drive fails anyway and the company cannot recover your data 😉
