TestDeviceAccess() does not display the sector count

[gnogni]

The function TestDeviceAccess() used in FDISK does not display the sector count correctly with Nextor versions 2.1.2 and 2.1.3.
Instead of showing the number, the letter "u" appears, likely a leftover from the %u notation used for printing the value.
Previously, Nextor 2.1.1 worked correctly with the same driver. The test was conducted on OCM.

I recall seeing this as well.

/*
    Bug:
    - Using "%u" formats an unsigned int (16-bit).
    - "sectorNumber" is an unsigned long (typically 32-bit).
    
    Solution:
    - Use "%lu" to correctly format an unsigned long.
*/

sprintf(buffer, "%lu", sectorNumber);
sprintf(buffer + strlen(errorMessageHeader), "%lu", sectorNumber);
