Public bug reported:
Binary package hint: parted
Please correct the "msftres" flag bug in libparted by deleting the
following code from (parted-source-dir)/libparted/labels/gpt.c :-
if (strncmp (fs_type->name, "fat", 3) == 0
|| strcmp (fs_type->name, "ntfs") == 0) {
gpt_part_data->type = PARTITION_MSFT_RESERVED_GUID;
return 1;
}
The "Microsoft Reserved" Partition in GPT is needed only for conversion
from a basic disk to dynamic disk in Windows. Otherwise it is not at all
needed and according to Microsoft, any FAT(16,32 etc..) or NTFS
partition(s) should be "Basic Data Partition" if they have to be
accessible in Windows and Mac (Linux allows access even to a msftres
partition).
Think of it like the 128 MB gap between partitions imposed by Mac OS X's
Disk Utility in GPT disk for future usage which cannot be anticipated at
present. Microsoft creates this partition for any future usage similar
to the 128 MB gap.
The above mentioned code in libparted assumes that any FAT or NTFS
partition must be marked as Microsoft Reserved (the same way any HFS
partition must be marked Apple_HFS), but this is not correct.
This bug can be corrected by either deleting the above lines or by
modifying them as follows :-
if (strncmp (fs_type->name, "fat", 3) == 0
|| strcmp (fs_type->name, "ntfs") == 0) {
gpt_part_data->type = PARTITION_BASIC_DATA_GUID;
return 1;
}
