I have synced whole geth into computer in --fast mode. However, it had to be stopped at one point today. Using the already downloaded data, can I pass the download phase and resume from where it is left?

If not, can I use the already downloaded data to speed up the sync?

As far as I know the current GoEthereum versions support snap sync by default. This is resumeable operation. You do not need to give extra command line parameters like --fast anymore to activate it.

Snap sync

My node synced under 8 hours using the default parameters.

More information about snap sync and its speed.
