Nothing to worry about, what is happening here is that your drive has a
host protected area and the drive fails to switch to that size (so you
only get the 36GB, not 40). You just lose a little capacity, that is all.
It could be a Linux error, actually. The above command is the 48-bit lba
variant of the SET_MAX command that can be used for this purpose, it
probably wanted to use 0xf9 instead. Maybe your drive advertises lba48
support but doesn't have it. It is a small drive, so it doesn't
necessarily support it. You can try changing
drivers/ide/ide-disk.c:idedisk_check_hpa() ala this pseudo patch:
- int lba48 = idedisk_supports_lba48(drive->id);
+ int lba48 = 0;
and compile + reboot that kernel.
