When this drive was in exFAT, it was 931,5 GB. After formatting to ext4 it’s only 915,8 GB, which are almost 20 GB lost. The way I formatted was sudo mkfs -t ext4 /dev/sda1. I know bytes can be counted deceitfully by manufacturers but this isn’t the case as the drive was 1 TB as opposed to the shown 931 GB, so there has been size loss.
The folder is completely empty and shows no file or folder at all. I don’t know about drives or what can cause it, but last time this happened was to some USB drive I burned an ISO on, which I haven’t to this big drive.
EDIT: This has nothing to do with reserved space. I mean the MAXIMUM listed space is still inferior. I forgot to clarify that I’ve already modified the reserved space and there is still size loss.
What you say matches what I’ve seen, I formatted again to FAT32 and it shown 931,5. And then reformatted to ext4 and marked 915,8.
But, why? I already expected this when I bought the drive, from 1 TB to 931. What I don’t understand is why AGAIN to 915. In theory makers count GB in units of 1000, so when converted to 1024 I expect the loss, that should be it. What made it to be counted differently two times? Does ext4 has some count form I’m not aware of?
