However in your case since the partition type appears to be listed already as 83 and the partition is reported as being HPFS/NTFS, I think I'd be inclined to delete the partition(s) all together and start over with a clean slate. The good news is you can use fdisk to change the partitions type through the t function: t change a partition's system idĪfter successfully doing this your partitions should looks something like this: Device Boot Start End Blocks Id System So to resolve your issue you'll need to change the partition type to 83 if it's a bare partition being formatted as EXT4, or 8e if it's an LVM partition. I should mention here that tools such as fdisk are "dumb" in the sense that they'll generally let you do whatever you want whether it makes sense to do so or not. So in your case you've mixed a partition type and a filesystem that generally don't go together. These are the filesystems that most are more familiar with when dealing with EXT3/4, etc. The second aspect to this is the formatting of the space within the partition itself (the filesystem). So in your case the partition is identified as being of type 17. ħ HPFS/NTFS/exFAT 4d QNX4.x 88 Linux plaintext de Dell UtilityĨ AIX 4e QNX4.x 2nd part 8e Linux LVM df BootItĩ AIX bootable 4f QNX4.x 3rd part 93 Amoeba e1 DOS accessĪ OS/2 Boot Manag 50 OnTrack DM 94 Amoeba BBT e3 DOS R/Oī W95 FAT32 51 OnTrack DM6 Aux 9f BSD/OS e4 SpeedStorĬ W95 FAT32 (LBA) 52 CP/M a0 IBM Thinkpad hi eb BeOS fsĮ W95 FAT16 (LBA) 53 OnTrack DM6 Aux a5 FreeBSD ee GPTį W95 Ext'd (LBA) 54 OnTrackDM6 a6 OpenBSD ef EFI (FAT-12/16/ġ0 OPUS 55 EZ-Drive a7 NeXTSTEP f0 Linux/PA-RISC bġ1 Hidden FAT12 56 Golden Bow a8 Darwin UFS f1 SpeedStorġ2 Compaq diagnost 5c Priam Edisk a9 NetBSD f4 SpeedStorġ4 Hidden FAT16 <3 61 SpeedStor ab Darwin boot f2 DOS secondaryġ6 Hidden FAT16 63 GNU HURD or Sys af HFS / HFS+ fb VMware VMFSġ7 Hidden HPFS/NTF 64 Novell Netware b7 BSDI fs fc VMware VMKCOREġ8 AST SmartSleep 65 Novell Netware b8 BSDI swap fd Linux raid autoġb Hidden W95 FAT3 70 DiskSecure Mult bb Boot Wizard hid fe LANstepġc Hidden W95 FAT3 75 PC/IX be Solaris boot ff BBT The valid partition types for MBR: Command (m for help): lĠ Empty 24 NEC DOS 81 Minix / old Lin bf Solarisġ FAT12 27 Hidden NTFS Win 82 Linux swap / So c1 DRDOS/sec (FAT-Ģ XENIX root 39 Plan 9 83 Linux c4 DRDOS/sec (FAT-ģ XENIX usr 3c PartitionMagic 84 OS/2 hidden C: c6 DRDOS/sec (FAT-Ĥ FAT16 <32M 40 Venix 80286 85 Linux extended c7 Syrinxĥ Extended 41 PPC PReP Boot 86 NTFS volume set da Non-FS dataĦ FAT16 42 SFS 87 NTFS volume set db CP/M / CTOS /. If you take a look at the structure of an MBR you'll notice that there is a section allotted for defining a partitions "type". Both of these lay down a "structure" on the disk.
CHDSK is verifying indexes (stage 2 of 5).
CHKDSK is verifying files (stage 1 of 5). The first is the act of laying down a partition table scheme on the disk using typically either MBR (Master Boot Record) or GPT (GUID Partitioning Table) formats. checking file system on F: the type of the file system is NTFS. When setting up a disk or partition there are 2 aspects to doing this.
