With the dmesg command I noticed that the disks are mounted at different times for each boot. Ubuntu 20.04 dual-boot Windows.
Fast boot:
$ dmesg ...[ 5.870528] EDAC amd64: F15h detected (node 0).[ 6.490309] EXT4-fs (sdd2): mounted filesystem with ordered data mode. Opts: (null).

(sdd2) (sdb2) (sdc1) are mounted quickly.
Slow boot:
$ dmesg...[ 8.596732] usbcore: registered new interface driver snd-usb-audio[ 12.256446] EXT4-fs (sdc1): mounted filesystem with ordered data mode. Opts: (null).

Maybe I did something wrong in the /etc/fstab?

Is there a way to always mount the disks at the same time as in fast boot?
Thank you guys :)
