Dear util-linux maintainer, i used a partitioning backup product of http://www.acronis.de/products/trueimage/ This software creates an extra partition named "ACRONIS Secure Zone " with the Recovery program and/or boot selector. After some examination i found out that the partition contains a standard FAT32 file system with a special initial program loader in boot sector, which tries to load Acronis loader F11.SYS or BOOTWIZ.SYS in older versions) To avoid that an user or a virus can compromise the restore software the partition is hidden by adding 0xb0=176 to partition number. So an FAT32 LBA (0x0c=12) gets number 0xbc=188. Maybe also partition with ids 01, 04, 06, 07, 0b, 0c, 0e are hidden in this way. See List of partition identifiers for PCs at http://www.win.tue.nl/~aeb/partitions/partition_types-1.html Unfortunately the software fdisk (util-linux-ng 2.13-rc2 and util-linux-ng-2.14-rc3 and util-linux-2.26) can not classify that partition. I send for the fdisk program my 2 patches so that fdisk recognize the Acronis partitions. pt-mbr-acronis.diff --- util-linux-2.26/include/pt-mbr.h.old 2015-02-10 10:49:46.000000000 +0100 +++ util-linux-2.26/include/pt-mbr.h 2015-03-25 19:30:49.000000000 +0100 @@ -150,2 +150,3 @@ MBR_BOOTWIZARD_HIDDEN_PARTITION = 0xbb, + MBR_ACRONIS_FAT32LBA_PARTITION = 0xbc, /* Acronis Secure Zone with ipl for loader F11.SYS */ MBR_SOLARIS_BOOT_PARTITION = 0xbe, pt-mbr-partnames-acronis.diff --- util-linux-2.26/include/pt-mbr-partnames.h.old 2015-02-10 10:49:46.000000000 +0100 +++ util-linux-2.26/include/pt-mbr-partnames.h 2015-03-25 19:18:53.000000000 +0100 @@ -73,2 +73,6 @@ {0xbb, N_("Boot Wizard hidden")}, + {0xbc, N_("Acronis FAT32 LBA")},/* hidden (+0xb0) FAT32 LBA with + ipl for Acronis loader F11.SYS + by Acronis partition backup software + is called Acronis Secure Zone */ {0xbe, N_("Solaris boot")}, Signed-off-by: Jörg Jenderek <joerg.jen.der.ek@xxxxxxx> Sorry that i do this way, but i have no knowledge about git toys.
