Mozna by to obsah mohl poskytnout obycejny klasicky fdisk - kdez to teda
je ta MBR
# fdisk -p /dev/da0
# /dev/da0
g c0 h64 s32
p 1 0x0c 35008 62551872
Tomuhle nejak moc nerozumim.
Netusite nekdo, jestli tohle jde nejak vyresit?
Napriklad zakazat kontrolu integrity
sysctl kern.geom.part.check_integrity=0 (nebo do loader.conf)
i kdyz to bych asi nenazval vyresenim jako spis zignorovanim problemu.
Bohuzel se to i tak porad tvari, ze to ma velikost jednoho sektoru:
# sysctl kern.geom.part.check_integrity=0
kern.geom.part.check_integrity: 1 -> 0
# diskinfo -v da0
da0
512 # sectorsize
512 # mediasize in bytes (512B)
1 # mediasize in sectors
0 # stripesize
0 # stripeoffset
0 # Cylinders according to firmware.
64 # Heads according to firmware.
32 # Sectors according to firmware.
AA33JJ7ZJFJG8N3C9RM7 # Disk ident.

Nahlednutim do
sys/geom/part/g_part.c:g_part_check_integrity()
je totiz videt, ze test neprojde jen kdyz je partition opravdu vadna.
Tim se mysli, ze nejaka partition konci driv nez zacina, konci az za
koncem fyzickeho media, jednotlive partition se prekryvaji a podobne
nepristojnosti.
Bootni to ve verbose rezimu, melo by ti to pri te prilezitosti rict co
konkretne se mu nezda ...
Zkusim jeste ten verbose rezim a pak pripadne zkusim celou slavnou
flashku zazalohovat a nejak prerozdelit / preformatovat na nejakem jinem
pocitaci / systemu, ktery to dovoli.
