Tipo de partição

O tipo de partição (ou ID de partição) em uma entrada de partição na tabela de partições dentro de um registro mestre de inicialização (MBR) é um valor de byte destinado a especificar o sistema de arquivos que a partição contém e/ou para sinalizar métodos de acesso especial usados para acessar essas partições (por exemplo, mapeamentos CHS especiais, acesso LBA, geometrias lógicas mapeadas, acesso a driver especial, partições ocultas, sistemas de arquivos seguros ou criptografados, etc.).

Visão geral

As listas de tipos de partições atribuídos a serem usados ​​na tabela de partições no MBR foram originalmente mantidas internamente pela IBM e pela Microsoft. Quando o mercado de sistemas operacionais de PC e ferramentas de disco cresceu e se libertou, outros fornecedores também precisavam atribuir tipos de partição especiais a seus produtos. Como a Microsoft não documentou todos os tipos de partição já designados por eles nem desejava manter as atribuições estrangeiras, os terceiros começaram a atribuir tipos de partição em seu próprio nome de uma maneira quase sem coordenação de tentativa e erro. Isso levou a várias atribuições duplas conflitivas, às vezes causando sérios problemas de compatibilidade entre determinados produtos.[1]

Diversos especialistas do setor, incluindo Hale Landis, Ralf Brown, Matthias Paul e Andries E. Brouwer nos anos 90 começaram a pesquisar tipos de partições e publicaram (e depois sincronizaram) listas de tipos de partições para ajudar a documentar o padrão de facto da indústria e, assim, reduzir o risco de novos conflitos. Alguns deles também ajudaram ativamente a manter software que manipula partições para trabalhar com as listas atualizadas, indicaram conflitos, criaram métodos adicionais de detecção e soluções para fornecedores ou também coordenaram novas atribuições de tipos de partições não-conflitivas.

Embora não seja oficialmente mantido,[1] novas atribuições devem ser coordenadas, em particular quaisquer novas atribuições de tipo de partição temporáriaa para projetos locais ou experimentais podem utilizar o tipo 7Fh para evitar conflitos com tipos já atribuídos. Este tipo foi especialmente reservado para uso individual como parte da iniciativa do Padrão de Partição de Desenvolvimento de SO Alternativo (AODPS, Alternative OS Development Partition Standard) desde 2002.[2]

Cabe ao gerenciador de inicialização ou ao kernel de um sistema operacional interpretar o valor. Portanto, a tabela especifica quais sistemas operacionais ou produtos relacionados ao disco introduziram um ID e qual sistema de arquivos ou tipo de partição especial eles mapearam para ele. As partições com tipos de partição desconhecidos para o software devem ser tratadas como espaços de armazenamento em disco reservados, porém ocupados, que não devem ser tratados pelo software, exceto pelos gerenciadores de partição.

Lista de IDs de partição

Esta é uma lista de conhecidos tipos de partições do registro mestre de inicialização em computadores compatíveis com o IBM PC:

Notas

  1. MS-DOS/PC DOS 2.0-3.1 cannot cope with hard disk partitions outside the first 32 MB of the disk. Therefore, FAT12 and FAT16 volumes in primary partitions physically residing outside this area must not use partition IDs 01h and 04h, even if they were otherwise small enough to be recognized by these DOS versions. In order to hide these volumes from these DOS issues 06h can be used instead. DOS distinguishes FAT types by their number of clusters, not by their partition ID, therefore, this does not cause any problems for DOS 3.31 and higher except for a possibly wrong file system type display in FDISK.
  2. QNX partition IDs 07h, 08h, 09h, 4Dh (77), 4Eh (78), 4Fh (79), as well as B1h (177), B2h (178) and B3h (179).
  3. Known partition IDs for logical sectored FATs include: 08h (Commodore MS-DOS 3.x), 11h (Leading Edge MS-DOS 3.x), 14h (AST MS-DOS 3.x), 24h (NEC MS-DOS 3.30), 56h (AT&T MS-DOS 3.x), E5h (Tandy MS-DOS), F2h (Sperry IT MS-DOS 3.x, Unisys MS-DOS 3.3 also used by Digital Research DOS Plus 2.1). While non-standard and sub-optimal these FAT variants are perfectly valid according to the specifications of the file system itself, although default issues of MS-DOS / PC DOS 3.x were not able to cope with them. Most of these vendor specific FAT12 and FAT16 variants can be mounted by more flexible file system implementations in operating systems such as DR-DOS simply by changing the partition ID to one of the recognized types. Also, if they no longer need to be recognized by their original operating systems, existing partitions can be "converted" into FAT12 and FAT16 volumes compliant with versions of MS-DOS/PC DOS like 5.0-6.3, which do not support logical sector sizes different from 512 bytes, by switching to a BPB with 32-bit entry for the number of sectors, as introduced since DOS 3.31, keeping the cluster size and reducing the logical sector size in the BPB down to 512 bytes, while at the same time increasing the counts of logical sectors per cluster, reserved logical sectors, total logical sectors, and logical sectors per FAT by the same factor.
  4. Used by OS/2 Boot Manager: 0Ah, 11h, 14h, 15h, 16h, 17h, 1Bh, 1Ch, 1Eh, 1Fh.
  5. HP Volume Expansion is a variant of SpeedStor and uses partition IDs 21h, A1h, A3h, A4h, A6h, B1h, B3h, B4h, and B6h.
  6. Used by Free FDISK of FreeDOS: 8Dh, 90h, 91h, 92h, 97h, 98h, 9Ah, 9Bh.
  7. Apple Mac OS X uses partition IDs A8h, ABh, and AFh.
  8. Versions of DR DOS 6.0 and higher use several of these partition IDs for secured FAT partitions with single-user security: C0h, C1h, C4h, C5h, C6h, CBh, CCh, CEh, CFh.
  9. Versions of IMS REAL/32 use partition IDs C0h and D0h for multi-user security.
  10. Versions of Multiuser DOS use these partition IDs for secured FAT partitions with multi-user security: D0h, D1h, D4h, D5h, D6h.
  11. Was suggested in now-superseded T13 EDD 4 proposal e09127r1 Arquivado em 19 de agosto de 2017, no Wayback Machine. (2009). The successor e09127r3 Arquivado em 1 de maio de 2018, no Wayback Machine. (2010) now recommends to use a normal partition type (the one that a legacy OS would see) instead of this special value.
