Grubutil FAT can give wrong available space on FAT32 partitions >= 4GB.
Total space is correctly calculated, but available space is sometimes wrong. Looking at function 'FAT info' number of free clusters is correct, sectors per cluster too.
In following case multiplication of number of free clusters and sectors per cluster is wrong, 'FAT mkfile' refuses to create a file. I observed same problem with 'FAT copy' earlier. Used is 8GB FAT32 device (hd1,0):
BTW output of 'FAT info' is compared with grub4dos script FATINFO.G4B (unpublished). This script directly reads-out all values from disk. So everything is fine, except result of multiplication in cases like these.
To me it seems the problem has something to do with free space >= 4GB. Maybe somehow with 64-bit values not fully 'good' in the multiplication, or while using the result of the multiplication?
