If HDD formatting was started and then interrupted, will I know about it?

Question

Hard disks

It may be that there was some kind of program or someone started the formatting process and was immediately interrupted, but the HDD remained readable, that is, the next time it is accessed, it will not require formatting. Or is this not possible? And if the formatting was interrupted, will the system ask you to format the HDD? OS Windows 10

Answer 1

At the beginning of the disk is the boot sector (MBR or GPT). At the beginning of each logical partition is a description of the partition. Formatting affects one of these descriptors (namely, creates it from scratch), so even if you immediately stop the process, the disk will be seen as cleared or damaged (and will ask you to format it)
The program can corrupt data on the disk by writing random data to a random disk block, but it's not formatting

Answer 2

formally, you can press the button and immediately cancel. In this case, nothing will happen.
In fact, you can press the button and nothing will happen, because there are not enough rights, for example. Or a warning will pop up and formatting will be canceled. In these cases, you won't know anything.
But if the formatting was physically started and then canceled, then there will be mess in the data. It will be impossible not to notice.

Answer 3

Well, if it’s fast there for a few seconds, you usually won’t even have time to cancel if it’s full, then it will ask you to format
