Extended Partitions not found on Easus Partition Management
How am I supposed to get more than 4 partitons?
Extended Partitions not found on Easus Partition Management I must be confused, but I've created 3 primary partitions on the new harddrive, and when I wanted to make an extended partition, Easus PM (dl'd only a week ago) only had two choices, Primary and Logical. I fell for it and made a logical partition and then couldnt understand why I coudln't subdivide it. I'd forgotten the word extended, but I remember it now. I deleted the logical partition and tried to make an extended one, but that wasn't a choice!! My gosh it's not mentioned in the Help for Win Disk Management either. How am I supposed to get more than 4 partitons? |

How am I supposed to get more than 4 partitons? Picture confirming the strange design of that tool. http://www.partition-tool.com/images...to-logical.gif Notice, in the example, the three green ones on the right are Logical. And the person making the example, is converting partition I: to logical. That will require re-dimensioning the Extended, and putting the Logical inside it. The new logical I: , fits neatly on the left hand side of the Extended envelope. That's why they picked I: for their example, because it makes sense as a candidate for being logical. If they had clicked C: and selected "Convert to logical", as you know, there is only a maximum of one Extended per disk. So that request would have been denied. Paul |

| How am I supposed to get more than 4 partitons?
| Extended Partitions not found on Easus Partition Management | I've never seen a disk management program like that. Usually Extended is an explicit option. Extended is an empty Primary that can hold any number of Logical partitions. It looks like Easus is hiding the details in an attempt to simplify. It then fills the Extended with the first Logical you make, which makes no sense. There's no point in have an Extended if it just holds 1 Logical. The only option I can think of is to then resize your Logical and put another Logical next to it. |

How am I supposed to get more than 4 partitons? For MBR HDD, the root partition table is limited to 4 entries. Entries can either be Primary or Extended. The Primary partition is the partition that directly contains a file system. An Extended partition is merely a container for one Primary and one Extended partition - where the child Extended partition may contain another Primary and Extended partitions (just like its parent Extended partition). In a partition table (MBR/EMBR), there can be only one Extended partition and it doesn't need to be the last entry. A logical partition is a Primary partition listed in a partition table of an Extended partition (EMBR), so a logical partition requires an Extended partition as its container. IOTW, an Extended partition's data is one or more Primary/Extended partitions. A layout of a HDD with more than 4 partitions (that contains a file system) would be like this. HDD MBR: Partition1=Primary=FAT32 Partition2=Primary=Ext4 Partition3=Primary=NTFS Partition4=Extended (EMBR): Partition5=Primary=HFS+ Partition6=Extended (EMBR): Partition7=Primary=JFS Total: Partition table entries = 7 Volume partitions = 5 In Easus, creating a logical partition means that an Extended partition will be automatically created when necessary. This is just to simply things so that you don't have to create the mandatory Extended partition manually. And yes. The software documentation doesn't tell everything you need to know. Not every partition manager softwares do. |

| The Primary partition is the partition that directly contains a file

An Extended counts as a Primary. It does not hold a Primary. It holds Logical by definition. There's no need to get into complicated details. *There can be 4 Primaries. One of those can be Extended. Extended can hold any number of Logical, each with any kind of formatting. Some OSs must be installed to a Primary partition.* That's pretty much the whole story. Micky just needs to know that Easus is not being clear and that his Logical partition is necessarily contained in an Extended. |

How am I supposed to get more than 4 partitons? Extended Partitions not found on Easus Partition Management With MBR (Master Boot Record), you can only have 4 *physical* partitions on a device (disk). That's it! The partition type can be primary or extended. There can can 1 to 4 primary partitions. There can be a maximum of 1 extended partition per device. The MBR only has 4 records for physical partitions. That is why there is a limit of 4 physical partitions of whatever type when using an MBR. The physical partitions (primary and extended) are tracked or defined by the 4 partition records within the partition table within the MBR. Logical drives are tracked or defined by structures defined *within* an extended partition. If you have 4 physical partitions already defined in the MBR, you reached the maximum number of partition records available in its partition table. Are all those physical partitions of the primary type? If so, you have no extended partitions within which you can define logical drives. If one of them is an extended partition type then you can define logical drives within that extended partition. For more information, read: https://en.wikipedia.org/wiki/Extended_boot_record https://en.wikipedia.org/wiki/Disk_p...nded_partition I must be confused, but I've created 3 primary partitions on the new harddrive, and when I wanted to make an extended partition, Easus PM (dl'd only a week ago) only had two choices, Primary and Logical. It is helping you too much. An extended partition with no logical drives defined with it is wasting disk space. An extended partition is a superstructure to encompass the definition of logical drives within that partition. There is no point in creating an extended partition unless you ALSO create a logical drive within it. So the tool is eliminating asking you to create an extended partition and then asking you to create a logical drive within the extended partition. Instead it just asks if you want to create a logical drive and, if so, then it will create the extended partition, if missing, and add the logical drive's definition within the extended partition. If you elect to create a logical drive, either an extended partition must already exist or one must be created. The logical drive resides within an extended partition. I fell for it and made a logical partition and then couldnt understand why I coudln't subdivide it. I'd forgotten the word extended, but I remember it now. I deleted the logical partition and tried to make an extended one, but that wasn't a choice!! There can only be 1 extended partition on a disk when using MBR. So if there is already a physical partition of the extended partition type then you cannot create another one. You would have to delete the extended partition to create a new one. If you define the logical drive to consume all of the space inside the extended partition then you have no more room to define more logical drives inside that partition. With physical partitions, you cannot assign more space to them altogether than the physical space available on the disk. With logical drives, you cannot assign more space to them altogether than the physical size of the extended partition. As I recall (but I did not check), only primary partitions can be marked "active" so the BIOS knows which one to use its boot sector to load an OS. The active-flagged primary partition boots the OS (well, at least the the boot loader for the OS). MBR ..---------------------------------. | Primary partition #1 | |---------------------------------| | Primary partition #2 [optional] | |---------------------------------| | Primary partition #3 [optional] | |---------------------------------| | Extended partition | | .-----------------------------. | | | Logical drive #1 | | | |-----------------------------| | | | Logical drive #2 [optional] | | | |-----------------------------| | | : : | | : : | | |-----------------------------| | | | last logical drive | | | '-----------------------------' | '---------------------------------' My gosh it's not mentioned in the Help for Win Disk Management either.

If you want more *logical drives* within an extended partition than you either have to make them smaller to make free space WITHIN the extended partition for a new logical drive or you have to enlarge the extended partition (perhaps by shrinking the other physical partitions) so there is room inside of it for a new logical drive. So just what partition *types* are currently defined on your disk? How many of them are primary partitions? Is one of them an extended partition type? |

Actually I think that's the one I just noticed on the Hiren's disk. I know it started with Mini. This has more options than I have tried and works really well. I made what is supposed to be a clone of the active partition. There should have been a boot menu but there isn't. But for testing, I was going to make the new partition active and see if it boots. Then came the warning that I might never be able to boot the disk again. That seems rather alarmist since it's not Never, and they could have pointed out booting from another source and changing which part. is active. But it scared me enough to go check that Hirens had something good on it. It probably has 3 or 4 but this one was a windows program, with a GUI. and probably easier to use. |

From this answer and all the others, I'm convinced of that now. It's nice to be simple, but if they had put one short entry in their help file (and they have a standard help file) under Extended. To simplify things, we have eliminated the need to create extended partitions. Just make logical ones and we'll fill in the rest. That would have helped. It then fills the Extended with the first Logical you make, which makes no sense. There's no point in have an Extended if it just holds 1 Logical.

How am I supposed to get more than 4 partitons? I appreciate your detailed very helpful post, but I have to take issue with this one point, at least semantically. You can't when using MBR. There are only 4 partition records in which you can define 1 to 4 physical partitions (primary or 1 extended). If You're not counting logical partitions as partitions. You call them logical drives but I've seen them called partitions. It reminds me of the question Abe Lincoln used to ask. How many legs does a horse have if you call its tail a leg? you want more *logical drives* within an extended partition than you either have to make them smaller to make free space WITHIN the extended partition for a new logical drive or you have to enlarge the extended partition (perhaps by shrinking the other physical partitions) so there is room inside of it for a new logical drive. So just what partition *types* are currently defined on your disk? How many of them are primary partitions? Is one of them an extended partition type? Four. Calling it a leg doesn't make it a leg. But a leg is more well defined than a partition. So I let Easus do it, and it seems to be fine, and I went into Windows Computer Management and before I had looked at actions or something and didn't notice that at the bottom there was a legend that included dark green for extended partition. And indeed, my 3 little partitions together are so marked. Thanks and thanks all of you. |

Earlier today, I cloned the C partition to the D using XXClone and I just checked and it boots just fine, except that there is no boot menu yet. But if I change the active partition, D boots just find (but with different wallpaper, an XXClone option so you can keep track of which partition you are using.) So things are going well. Again, thank you all for your help. |

You're not counting logical partitions as partitions. You call them logical drives but I've seen them called partitions. The physical partitions are the only *partitions* on the disks. That's because they are the only objects that can be defined in the *partition* records in the *partition* table. The structures defined within an extended partition are not partitions. They are drives or perhaps also called volumes. They are NOT partitions within the extended partition. [There are] Four [partitions]. Then you cannot create another partition. You have used up all 4 *partition* records in the *partition* table within the MBR. From your other reply, you have the maximum of 4 physical partitions so all 4 partition records are consumed in the MBR: 3 primary and 1 extended. Within the extended partition, you have 4 logical drive structures defined. Whether all of the extended partition's space got consumed by the 3 logical drive structures within it is yet unknown. To create yet another logical drive means: - There is unused (unallocated) space inside the extended partition that you can use to create another logical drive. - You will have to resize the logical drives inside the extended partition to free up some space so there is then unallocated space inside the extended partition to create another logical drive within it. - You enlarge the extended partition to give it unallocated space inside of it to which you can assign a logical drive. If the 4 physical partitions (3 primary, 1 extended) have consumed all spaced on the disk then you will have to shrink one, or more, of the primary partitions so you can enlarge the extended partition. Because EPM gave you the choice of creating another logical drive inside the extended partition, you have some unallocated space inside the extended partition. Whether it is enough space depends on what purpose you intend for the new logical drive. So I let Easus do it, ... Since you want to get into "semantics", the tool from Easeus is actually called Partition MASTER [Pro], not Partition Management [Pro]. http://www.easeus.com/partition-manager/epm-free.html http://www.easeus.com/partition-manager/epm-pro.html You didn't bother to mention if you are using the freeware or payware version. |
