waitusb for usb hard disk ?

[P5music]

hi
I had to use waitusb=10 boot option using a pendrive tdk 4Gb.
I would like to know if waitusb=10 is necessary for usb hard disks too.
thanks in advance

Try it and find optimum value.

is it likely to be the same for pendrive and hard drive according to your experience?
is there a trick for the usb device to be recognized with some low-level parameters from the previous boot?

Hard drives tend to spin up slower than flash ones.

For a very rudimentary measure, boot with "debug base norestore pause" and without waitusb. Start counting on the "press enter" prompt until the usb messages arrive, add 2-3s to be safe.

when waitusb is called the hard disk has already spinned up because it is the linux system that awaits to recognize the drive or pen, according to my understanding of the boot process.
so my goal is to make tinycore read some boot parameter so it does not wait because it already knows what it has to know.
the installation will start just on one computer.
