What Does Repartition Hard Drive Windows 10 Do?
Repartitionahard drive inWindows10 referstoreallocate orreassignharddrive space to hard drive
partitions.Itwill change the harddisklayoutwith the numberof partitionsandlocationof
partitions.Repartitioningwill alsochange the specificationsof involvedpartitionincludingpartition
size,label,driveletter,partitiontype (primaryorlogical),filesystem(NTFS,FAT32,etc.),aswell as
clustersize,etc.
Why Need to Repartition Hard Drive in Windows 10?
Usually,whenyoubuya computereithernew orold,itwill come withharddrive(s) that hasalready
partitionedbyitsmanufacturerorformerowner.Youmay be not satisfiedwiththe diskstorage
space arrangementandfindthe arrangementisunreasonable,especiallyforthe second-hand
machine.Evenforthe grand-newcomputer,afterseveral yearsof usage,youmaybe boredwithits
disklayout.So,youneedtorepartitionthe harddrives.
Or, afterusingthe harddrive foryears,youmay encounter low diskspace problems (usuallyhappens
to systempartitionC) whichmeansthe targetpartitionisrunningoutof storage space.If there isa

How to Repartition Hard Drive Windows 10 with Disk Management?
Whenit comesto hard drive management,formostusers,theywill thinkabout WindowsDisk
Management.Itis the systembuilt-intool formanagingharddisksconnectedtothe operating
system(OS) andtheirpartitions.
Firstof all,youshouldfindandlaunchDMon your computerinorderto make use of it.Right-click
on ThisPC (inWindows10) and selectManage;inthe pop-upwindow,chooseDiskManagement.
Or, search“diskmanagement”inthe Taskbar;in the searchresultlist,click“Create and formathard
diskpartitions”toopenDM. Or, use “Windows+ X” keysto triggerthe usermenu,andselectDisk
Managementinthe options.
Alt=Windows10 DiskManagement
Right-clickona commonpartitioninthe DiskManagement.Inthe drop-downmenu,youcansee the
actionsyoucan carry out withthe helpof DM, withthe highlightonesfeasible for the current
partition.Asyoucan see inthe belowscreenshot,the featuresavailable are:
 Open – Openthe partitionanddisplayitscontentsinWindows Explorer.
 Explore – Openthe partitionanddisplayitscontentsinWindowsExplorer.
 Mark PartitionasActive – Setcurrentpartitionstatusas active.Itis usuallyforsystem-
relatedpartitionsfromwhichyouwanttoboot.

3.  Change Drive LetterandPaths – Change the drive letterof the currentpartition.Youcan
alsoadd a drive letterorpath forthe currentvolume,ordelete the currentpartition’sdrive
letter(will cause itscontainedprograms notrunning).
 Format – Format currentpartitionof itsvolume label,file system, andallocationunitsize
(blocksize).
 ExtendVolume –Extendcurrentpartitiontoenlarge itssize withunallocatedspace right
nextto it.
 ShrinkVolume –Shrink the currentpartitiontodecrease itssize andspare out some
unallocatedfree space.
 AddMirror – Adda mirrorto the current partitiontoprovide dataredundancyby
maintainingmultiple copiesof apartition’sdataon differentdisks.
 Delete Volume –Delete currentpartitionandthe dataon it.
 Properties –Showthe propertyparametersof the currentpartition.

Whenwe talkabout repartitionharddrive Windows10,usually,we refertoextendsmallpartitions
like systempartition,shrinklarge datapartitions,delete unwantedpartition,create anew partition,
etc.

4. Delete Partition with Disk Management
Deletingapartitionwill alsodelete all the datastoredonit.Before starting,youare recommended
to back up importantfiles ontargetpartitionandsave the copyon anotherplace,betteronanother
hard diskdrive,oran external harddrive,USBflashdrive,etc.
For deletinganexistingpartitioninDiskManagement,youshouldright-clickonthe partitionyoudo
not needanymore andselect Delete Volume.Readthe warningandclick Yes.
Create Partition Within Disk Management
In DM, you are onlyable to create partitionsfromthe unallocatedspace.Youcan’tcreate a partition
fromthe free space withinanalreadyexistingpartition.If there isn’tany unallocatedspace onthe
hard drive,youcan’tcreate a partitionunlessyoudeleteone orall existingpartitionstomake some
unallocatedspace accordingtothe guide inthe above.
Suppose there isalreadysome unallocatedspace,youcancreate a partitiononit. Just follow the
guidance below:
1. Right-clickonthe unallocatedspace andchoose NewSimple Volume orotherkindsof volumes
youlike if yourconditionsupports.
Alt=Create NewPartition
 New Simple Volume –Create anew partitionthatonlylocatesonone physical drive.
 New SpannedVolume–Create a new dynamicvolume thatlocatesonat least2 physical
disks. Suchkindof volumeshasnofaulttolerance.

5.  New StripedVolume–Create a new dynamicvolume thatlocates onat least2 physical disks
and all physical drivesprovide the same amountof storage space.Suchkindof volumes
improve readandwrite speed,buttheydon’thave faulttolerance.
 New MirroredVolume –Create 2 identical dynamicvolumesthatlocate on2 physical drives
respectively.Whenyouwrite dataintothe mirroredvolume,itactuallywritesthe same data
intothe two identical volumessimultaneously.So,the availablespace of a mirroredvolume
isactuallyhalf of its size.When eitherof the 2 identical volumesfails,the otherone can
worknormally.So,the mirroredvolume isfault-tolerant.
 New RAID-5Volume –Create a new dynamicvolume basedon atleast3 dynamichard
drives.A RAID-5volume hasfaulttolerance andfastread& write speed.
2. Read the notificationandclick Next.
3. Specifyvolume size andclick Next.
Alt=SpecifyVolume Size
4. Assigna drive letterorpath.

6. Alt=AssignDrive Letteror Path
5. Format the newpartitionwithitsfile system, allocationunitsize,aswell as a volume label.
Alt= FormatNewPartition

7. 6. Read the notificationandclick Finish.Finally,youcansee the new partitioninyourDisk

That is all aboutcreatinga newpartitionforrepartitionharddrive Windows10.
Shrink Partition by Disk Management
Usually,usersneedtoshrinkalarge partitionwithmuchfree space to getsome unallocatedspace.
Then,theymake use of the unallocatedspace tocreate a new partition.
1. Right-clickonsource partitionandselectShrinkVolume.
2. In the pop-upwindow,specifyhowmuchspace toshrinkout.
Note:You can’tshrinka partition beyond thepointwhereany unmovablefilesare located.

8. Alt=SpecifyShrinkSpace
3. ClickShrink and youcan see the result.
Alt=SuccessfullyShrinkVolume

9. Extend Partition Through Disk Management
Justas mentionedinthe above,youcanonlyextendapartitionwithunallocatedspace rightbehind
it.If there isno suchunallocatedspace,youcancreate some bydeletingthe existingpartition
behind.
How aboutshrinkingone partitionforsome unallocatedspace?No,itdoesn’thelp!The shrinking
out space islocatedrightbehind itsoriginal partition;youcannotuse itto extendotherpartitions
insteadof the original one (thatismeaningless). So,the onlywayforcreatingunallocatedspace for
extendingone partitionistodeletethe partitionthatisrightbehind.
Tip: You should firstly movethe dataon the partition thatyou are going to delete to anotherplace
beforedeletion.
Suppose there isalready unallocatedspace rightbehind the targetpartition,justfollow the below
stepsto extendthe targetvolume.
1. Right-clickontargetpartitionandchoose ExtendVolume.
2. Read the notificationandclick Next.
3. Selectfromwhichdiskto take free space from, andhow muchfree space you’dlike totake.
Alt=SelectDiskswithAvailable Free Space
4. Read the notificationandclick Finish.Finally,youcansee the targetpartitionisextended.

Wizardcan recoverlostdataand partitionsonthe hard disk, testdiskreadand write speed under
setsituations,analyze harddrive space andlistfolders/filesbasedontheirsizes,merge/split
partitions,move apartitiontonewlocation,partition/disksurface test,andsoon.
To use PartitionWizard,youshouldfirstof all downloadandinstall itonyourcomputer,betternot
on the hard drive youplanto repartition.If there isonlyone harddiskinyourmachine,youcan try

(extend),or, byinputtingasize number.Or,youcan justkeepthe defaultspace allocationof
assigningthe same space toboth partitions.

12. Alt=SpecifyNewPartitionSize
Step 3. Previewthe changesin the diskpartitionlayout.If youare satisfiedwithit,click Applyinthe
lowerlefttosave the changes.Fromthe PendingOperationslist,you can figure outthat splitting

Tip: You can also extend a partition with an existing partition by merging themtogether.The data on
bothpartitionswill also be merged into thenew partition.
