Hello,
I'd like to read raw sectors (blocks) from removable devices (such as USB drives) from Linux and/or Windows. Is there any possibility to use FPC with that?
Thank you very much,
Mihai

Under linux, I suppose you can simply open the file device. /dev/sgN, under windows, I don't know.
In each case, FPC does not offer a platform independent low-level hardware access... The naming schemes for devices are wildly different on these platforms...
Michael.

On Linux you can read the device like a normal file.
On Windows there is probably a API function to do this. Do some googling to find it.
And then use {$ifdef Win32} and other conditional compiles to ensure it compiles across all platforms.
There is some explanation on how to use the conditional compiles here:
