5 to read the disk's partition table when compiled with the latest popt
6 (commit 740, which is pre-release as I type; presumably version 1.19 and
9 - Updated guid.cc to deal with minor change in libuuid.
11 - Fixed potential NULL derefernce bug in sgdisk. Thanks to Damian Kurek
14 - The partition number of "0" can now be used to reference newly-created
15 partitions when the --largest-new=0 option to sgdisk is used. Thanks to
18 - Make explicit casts in gptcurses.cc to eliminate compiler warnings about
19 mis-matched types in printw() statements.
21 - Minor code cleanup based on valgrind analysis.
23 - In previous versions, GPT fdisk accepted only integer values for partition
30 - Changes to optimize disk handling, particularly on Windows, courtesy of
33 - Added numerous new partition type codes from Discoverable Partitions
35 (https://uapi-group.org/specifications/specs/discoverable_partitions_specification/).

46 when changing a partition's name with sgdisk (-c/--change-name).
48 - Added support for aligning partitions' end points, as well as their start
51 by the new '-I' option in sgdisk. See the programs' respective man pages
56 - Added check for too-small disks (most likely to be an issue when trying
57 to use a too-small disk image); program now aborts if this happens.
59 - Added the ability to build sgdisk and cgdisk for Windows.

75 - Consolidated Makefiles for Linux, FreeBSD, Solaris, macOS, and Windows
76 (32- and 64-bit). The old OS-specific Makefiles remain in case the new
81 -----------------
83 - Fixed double byte swap operation on writes of partition name data on
84 big-endian systems; this is in addition to the double byte swap fix on
88 - Added feature to gdisk and sgdisk to enable swapping the byte order of
91 -b/--byte-swap-name in sgdisk. This seems advanced/obscure enough that I
95 - Added type code for the Barebox boot loader (0xbb00;
96 4778ED65-BF42-45FA-9C5B-287A1DC4AAB1).
98 - Trivial code cleanup.
101 ------------------
103 - Fixed bug that caused spurious warnings about the partition table
107 - Added ARM64 as an architecture for the Mac builds of gdisk and fixparts.
109 "universal" x86-64/ARM64 binaries, so they will run natively on the new M1
111 for x86-64, because they rely on libraries that are not easily built in
114 - Fixed double byte swap operation on partition label data on big-endian
117 - Added three new type codes:
118 - 0x0701 - Microsoft Storage Replica
119 - 0x0702 - ArcaOS Type 1
120 - 0x8401 - Storage Performance Development Kit (SPDK) block device
123 ------------------
125 - Fixed bug that could cause segfault if GPT header claimed partition
127 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-0256
129 - Fixed bug that could cause a crash if a badly-formatted MBR disk was
131 https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-0308
133 - Renamed the partition type "Freedesktop $BOOT" to "XBOOTLDR partition".

165 - It's now possible to quit out of partition type name searches by typing
168 - When changing a partition type code, the default is now the current
169 type code, not a platform-specific type code.
171 - The UEFI GPT fdisk project
179 - Apple no longer supports building i386 or "fat" binaries in XCode (or if
181 macOS binaries are now x86-64 only. Similarly, building now seems to
183 also re-built my Mac build environment and tweaked Makefile.mac
187 -----------------
189 - Added some explicit copy constructors and made some other tweaks to avoid
192 - The macOS binary for sgdisk is now a pure 64-bit build; I'm no longer
193 supporting 32-bit builds of sgdisk. The gdisk and cgdisk binaries remain
194 "fat" 32-/64-bit builds. The reason for dropping the 32-bit support from
195 sgdisk is that I've re-built my macOS development system, and I had
197 libraries upon which sgdisk relies. 32-bit support for the other binaries
200 - Added search feature to partition type list functions ("L" on main menu of
205 descriptions. Note that the search/filter is case-sensitive. If <Enter> is
208 - Change to Makefile.mac to use standard libncurses rather than a 3rd-party
211 - Minor bug fix in alignment of internal data structures.
213 - Minor bug fix in handling of damaged disks. Also, GPT fdisk now reports

217 - Added type code for Apple APFS (7C3457EF-0000-11AA-AA11-00306543ECAC,
220 - Added type code for Atari TOS basic data (0xa200,
221 734E5AFE-F61A-11E6-BC64-92361F002671).
223 - Added type codes for Linux dm-crypt (0x8308,
224 7FFEC5C9-2D00-49B7-8941-3EA10A5586B7) and LUKS (0x8309,
225 CA7D7CCB-63ED-4C53-861C-1742536059CC) partitions.
227 - Added 18 Ceph partition type codes.
229 - Added 52 (yes, 52!) Android partition type codes.
231 - Changed "Creating new GPT entries" message to read "Creating new
233 using sgdisk with a non-destructive option, like "-p".
236 ------------------
238 - Fixed a major bug that caused invalid partition tables to be generated
239 when creating a new partition table (that is, partitioning a blank disk or
243 ------------------
245 - On Linux, the p/-p/--print command now shows the disk's model name, as
249 when accessing disk image files, even on Linux.
251 - GPT fdisk can now report both the physical and logical sector sizes of
258 - Addition of new verification checks, mostly (but not exclusively) related
259 to the new j/-j/--move-main-table option.
261 - Added new option: 'j' on the experts' menu in gdisk;
262 '-j/--move-main-table={sector}' in sgdisk. This option enables relocating
264 else on the disk. The main reason I know of to do this is if the disk is
265 to be used with a system-on-chip (SoC) computer, some of which require the
271 - Updated man pages with new recommendations for ESP and BIOS Boot Partition
274 - Added four type codes (AF06 through AF09) for Apple SoftRAID (Status,
277 - Added two type codes for the Open Network Install Environment (ONIE):
278 0xe100 (7412F7D5-A156-4B13-81DC-867174929325) and 0xe101
279 (D4E6E2CD-4469-46F3-B5CB-1BFF57AFC149).
281 - Added thirteen type codes for Android partitions (0xa000 through
284 - Added type code for QNX6 (aka QNX Power-Safe) filesystem: 0xb300, for
285 CEF5A9AD-73BC-4601-89F3-CDEEEEE321A1.
287 - Removed stray debug message ("REALLY setting name!") from sgdisk,
288 when setting new name via -c option.
291 -------------------
293 - Created uninstall-fixparts and uninstall-gdisk scripts for OS X. As the
297 - Fixed bug that caused -N/--largest-new option to sgdisk to fail when
300 - Fixed bug that caused input glitches in EFI version of gdisk.
302 - Fixed bug that caused sgdisk to not return an appropriate error code
305 - Fixed bug that caused cgdisk's "Info" display to under-report the
308 - OS X 10.11 includes new security features that prevent GPT fdisk from
311 into the normal system. You can re-enable the security features by
314 this feature when gdisk detects that it can't write to the disk under OS
318 - I've updated the OS X installation location from the Unix-standard
324 - I've updated my OS X environment to OS X 10.11 and LLVM 7.0.0. This has
328 systems.) The OS X binaries are now "fat" (32- and 64-bit) versions,
330 32-bit support, in which case the binaries will now work.
332 - Changed the default name of 0xab00 partitions from "Apple boot" to
338 - Changed the OpenBSD type codes (0xa600 and 0xa601): 0xa600 is now
339 824CC7A0-36A8-11E3-890A-952519AD3F61 (OpenBSD disklabel) and 0xa601 is
340 now gone. Previously, 0xa600 was 516E7CB4-6ECF-11D6-8FF8-00022D09712B, a
342 824CC7A0-36A8-11E3-890A-952519AD3F61. OpenBSD is now officially
343 supporting 824CC7A0-36A8-11E3-890A-952519AD3F61 as a disklabel type,
345 non-disklabel type codes at the moment.
347 - Added GUID 0311FC50-01CA-4725-AD77-9ADBB20ACE98 (0xbc00) for
350 - Fixed bug that caused random crashes on ppc64el systems (and perhaps

355 - Added GUID 69DAD710-2CE4-4E3C-B16C-21A1D49ABED3 (0x8307) for 32-bit ARM
360 - Edited man pages to clarify that default alignment is to 1MiB boundaries;
361 this translates to 2048 sectors on disks with 512-byte sectors, but it
364 - Changed behavior of -z/--zap and -Z/--zap-all options to sgdisk so that
365 if a subsequent command causes changes, they'll be written to disk.
366 Previously, doing something like "sgdisk --zap-all --clear /dev/sdd"
367 would wipe the disk but not create a partition table; to create a blank
368 table you'd need to do "sgdisk --zap-all --clear --mbrtogpt /dev/sdd",
369 which is a bit odd and counter-intuitive, to the point of arguably being
373 ------------------
375 - I'm now building a binary package of gdisk_x64.efi, using the UEFI GPT
378 - Added partition type for OpenBSD data
379 (824CC7A0-36A8-11E3-890A-952519AD3F61/0xa601). Also mapped 0xa600 to the
380 FreeBSD disklabel type code (516E7CB4-6ECF-11D6-8FF8-00022D09712B). I'm
384 - Added partition type for Windows Storage Spaces
385 (E75CAF8F-F680-4CEE-AFA3-B001E56EFC2D/0x4202)
387 - Added -O/--print-mbr option to sgdisk, enabling easier display of MBR
390 - Updated warning message: "EBR describes a logical partition" now reads
393 - Altered warning displayed when run from Windows on non-GPT disk, because
394 Windows on UEFI-based systems is becoming more common.

420 ------------------
422 - Added feature to sgdisk's -A/--attributes, -c/--change-name,
423 -t/--typecode, and -u/--partition-guid commands: If a -n/--new option
426 them to use the newly-created partition. For instance, "sgdisk -n
427 0:0:+550M -t 0:EF00 /dev/sda" creates a new partition with a type code of
428 EF00. (Previous versions would ignore the "-t 0:EF00" option.)
430 - Fixed bug that caused incorrect partition number to be displayed by
431 sgdisk in error messages when the user specified a non-existent partition
434 - Fixed new (in 0.8.9) bug that caused a failure to create more than one
437 - Fixed bug that caused gdisk and sgdisk to create hybridized partitions
450 ------------------
452 - Removed dependency on libicu for UTF-16 support.
454 - Fixed spurious "0xEE partition doesn't start on sector 1" warning in
457 - Added GPT regeneration command to GPT-destruction options ('z' in gdisk,
458 -z and -Z options to sgdisk). This is done to avoid wiping out data
459 mid-disk that might not be backup GPT data structures, which could
462 - Added check for an oversized 0xEE protective partition. The program now
463 auto-repairs this condition on loading if the GPT data seem otherwise
468 - If the GPT data seem to be damaged in some way or if the disk seems to
469 be a hybrid MBR and if the MBR partition(s) don't fit on the disk, the
470 verify (v) function now warns of this condition, and writing the disk if
473 - Added new type codes (3000, 7412F7D5-A156-4B13-81DC-867174929325 and

477 - Added new type ccde (ED01, BFBFAFE7-A34F-448A-9A5B-6213EB736C22), for
478 Lenovo's ESP-like partition.
481 -------------------
483 - Fixed bug that could cause segfault when passing an invalid partition
484 number to sgdisk's -i/--info command.
486 - Added new type code: 933AC7E1-2EB4-4F13-B844-0E14E2AEF915, or gdisk code
488 versions of systemd to permit /home to be auto-mounted; see
489 http://www.freedesktop.org/software/systemd/man/systemd-gpt-auto-generator.html
492 - Added new type code: 9E1A2D38-C612-4316-AA26-8B49521E5A8B, or gdisk code
495 - The number of partition type codes has grown large enough that it fills

502 on sector 1: Previously, a disk with multiple 0xEE partitions would
506 - Fixed hybrid MBR creation on disks larger than 2TiB: Previously, if one
510 - Added check for an active/bootable 0xEE protective partition to the
513 VirtualBox's EFI) to ignore the disk.
516 -----------------
518 - Modified Mac version so that it can work on /dev/rdisk* devices as well
519 as /dev/disk* devices. The result is that, when using the /dev/rdisk*
520 devices, the partition table can sometimes be re-read without removing
521 the disk or rebooting.
523 - Added "-a" option to cgdisk to use a ">" symbol to the left of the
526 - Modified "converting MBR to GPT" message to clarify that the conversion
528 "gdisk -l" operation will change an MBR disk to a GPT disk without
531 - Added partition type code for freedesktop.org's proposed $BOOT partition
532 (bc13c2ff-59e6-4262-a352-b275fd6f7172; GPT fdisk type code EA00)
534 - Adjusted alignment code when using -n or -N in sgdisk to keep the
542 - Fixed small bugs in gdisk_test.sh script.
544 - Removed stray debug message that would appear when reading MBR disks.
546 - Added partition type code for Intel Rapid Start partition (GUID
547 D3BFE2DE-3DAF-11DF-BA40-E3A556D89593, code 8400), used by systems that
549 http://blog.adios.tw/2012/10/funtoo-linux-and-intel-rapid-start.html or
552 - Added partition type code for Haiku BFS (GUID
553 42465331-3BA3-10F1-802A-4861696B7521; code EB00).

587 failed, although everything else worked. (I suspect anti-virus software
590 - Added type codes for Midnight BSD (0xA580 - 0xA585). I used these codes
596 ------------------
598 - REALLY fixed Ctrl+D problems! Now gdisk terminates upon receiving a
599 Ctrl+D. In all previous versions, it could lock itself into a CPU-hogging
605 ------------------
607 - Fixed compilation problem on GCC 4.7.
609 - Improved handling of Ctrl+D on some systems.
611 - Added disk's name to message stating that a disk write was successful.
613 - Fixed bug that caused creation of >2TiB partitions on 32-bit systems to
617 ------------------
619 - Adjusted the code to support a number of partitions that's not a multiple
627 - Fixed bugs relating to the handling of empty partitions; Solaris's ZFS
629 handling properly. (Specifically, they sometimes have non-zero end
632 - Fixed a bug that caused an infinite loop of input prompts if the user
635 - Changed gdisk's first-sector input operation to specify a sector number
639 disk (as well as in some other situations).
642 ------------------
644 - Fixed bug that could cause FixParts to keep a partition's assignment
651 - Added code to detect infinite loops of logical partitions when reading
655 - Fixed bug in partition overlap detection in MBR code.
657 - Changed GPT reading code to use the size encoded in GPT headers to
659 restriction that the size be equal to or less than the disk's sector

665 with over-512-byte sector sizes if the header sector is padded with
668 - Fixed bug in new (as of 0.8.0) check that main and backup partition
669 tables are identical on big-endian (PowerPC, etc.) hardware.
672 ------------------
674 - Added new return option for sgdisk: 8, which means that a replication
675 operation (-R or --replicate) failed. Note that other operations on
678 - Added gdisk_test.sh shell script, contributed by Guillaume Delacour.
682 - Enable sgdisk's -l (--load-backup) and -o (--clear) options to work
684 though, so if you suspect a disk may be bad and want to use one of these
688 - Added check for mis-matched primary and backup partition tables.
691 - Added Apple Core Storage partition type code (hex code AF05, GUID
692 53746F72-6167-11AA-AA11-00306543ECAC).
694 - Added cgdisk program to the family. This program is a rough workalike
696 man page or http://www.rodsbooks.com/gdisk/cgdisk-walkthrough.html for
699 - Fixed bug that caused CHS end point for protective MBR to be set to
700 0xfeffff rather than the spec-mandated 0xffffff on disks over ~8GB. This
705 ------------------
707 - The Windows version now (finally!) generates proper GUIDs rather than a
709 when converting a disk from MBR format (but, oddly, not when creating a
712 - Added a warning when an MBR partition is discarded because it's too
713 big for the disk.
715 - Changed warning to Windows users about the dangers of converting to GPT
718 - Fixed bug that caused bogus "3" values to pad the ends of partition names
719 on some disks (particularly those created by Microsoft's disk
722 - Made compilation without Unicode support possible (see README file)
724 - Made default filesystem type code OS-dependent (based on the compilation
727 - Added new Linux-only filesystem partition type GUID code,
728 0FC63DAF-8483-4772-8E79-3D69D8477DE4 (8300 entry code). Also changed name
729 of the EBD0A0A2-B9E5-4433-87C0-68B6B72699C7 (0700 entry code) to
732 - Fixed a bug that caused an incorrect code to be set for active/bootable
735 - Enable entry of hex codes that begin with "0x" for both GPT and MBR
738 - Fixed bug that caused the boot loader code to be lost when creating a
741 - Fixed bug in sector input code that could produce improper values
745 ------------------
747 - Added support for proper UTF-16LE partition names rather than the
756 - Added check to fixparts to keep it from operating on devices that
760 - Fixed bug that caused the protective MBR to not be written when
763 - Fixed bug that caused second protective MBR partition, when created
767 - Integrated a number of code cleanups contributed by Florian Zumbiehl.
770 ------------------
772 - Fixed bug that caused some types of logical partitions to be misread.
774 - Created FixParts program, to fix problems on MBR-partitioned disks.
778 - Completely redid the GPT-to-MBR code, used both for converting to MBR
781 - Fixed a bug that caused gdisk to "forget" some partitions if there were
784 - Improved CHS value creation on small (<~8GB) disks for protective MBR
785 and when creating hybrid MBRs or converting to MBR format. Linux-only,
786 for the moment; other platforms still produce bad CHS values on sub-~8GB
789 - Enhanced disk replication features ('u' on the experts' menu in gdisk; -R
790 or --replicate in sgdisk). It's now possible to replicate the partition
791 table from a larger to a smaller disk, so long as all the partitions fit
792 on the smaller disk. In sgdisk, the secondary GPT data are moved
793 automatically if disk sizes don't match. In gdisk, the secondary GPT data
794 are moved automatically if the target disk is smaller than the source
795 disk; if the target disk is larger than the source disk, the user is
798 - Fixed --load-backup (-l) option to sgdisk, which was broken.
800 - Changed largest drive that's not given a minimum 4 KiB alignment even
801 when smaller alignment is detected on the disk to 300 GB.
803 - Fixed bug that prevented aborting a partition table backup ('u' on the

934 sgdisk). This option randomizes the disk's GUID and all partitions'
935 GUIDs. Intended for use after cloning a disk with a utility that copies
936 the GUIDs intact (such as a raw dd copy) if you want each disk copy to

1005 - More alignment changes: GPT fdisk now attempts to determine the alignment
1009 the drive might be a WD Advanced Format unit that requires an 8-sector
1010 (or larger power-of-2) alignment value for best performance. The
1011 2048-sector default provides better alignment in some RAID

1097 protective MBR is generated (when doing an MBR-to-GPT conversion, when
1100 the existing MBR disk signature in most cases, but this resulted in
1101 values of 0x00000000 whenever an empty disk was partitioned, and often in
1105 - Added transpose ('t' on experts' menu in gdisk; or -r or --transpose in
1106 sgdisk) command to enable fine-tuning partition order without doing a
1109 - Added code to clear the MBR boot loader when doing an MBR-to-GPT

1196 - Compiles using MinGW (http://www.mingw.org) to create a Windows binary.
1198 - Moved all disk I/O functions to the new DiskIO class. This helps with the
1199 Windows port; it uses diskio-windows.cc for Windows-specific code,
1200 diskio-unix.cc for the Linux, FreeBSD, and OS X code, and diskio.cc for
1201 cross-platform disk I/O code.

1330 image files have 512-byte sectors.
1332 - Added verification prompt to 'o' main-menu option to avoid accidental
1335 - The "destroy GPT data structures" option ('z' on the experts' menu) now
1338 - Added an extra warning to the "destroy GPT data structures" option if an APM

1359 size. For instance, "-200M" creates a partition that ends 200MiB before
1362 - You can now specify the start point of a partition by using a plus or
1364 the start (+) or end (-) of free space. This is exactly the same as the
1368 - Deleting a partition now checks for a matching hybrid MBR partition, and
1371 If no non-0xEE partitions are left, a fresh protective MBR is generated.

1411 the big-endian support while developing 0.4.0.
1413 - Tweaked the disk type identification code to warn users to re-sync their
1416 - Tweaked MBR-reading code to ignore 0xEE (EFI GPT) partitions. This will
