My laptop is kinda old.15da0411tu Intel Core i3 8th Gen 8130U - 4 GB ram /1 TB HDD/Windows 10 HomeI tried checking the disk management, but there was no option showing unallocated space . Can I recover the lost space?is there any way? Please help me.

W7 Hard drive partition issue

to get rid of that 100 meg windows partition that setup creates for you on a new install on a blank hdd:

- press shift+f10 when on the partition management screen in setup <-- this opens a command prompt
- diskpart <-- start the windows command line partition management tool
- list disk <--- list the installed hdds in this computer for the next step
- select disk 0 <- might have to replace 0 with the number of the correct disk
- clean <-- this will erase all data on the disk you selected one step up- dont use the wrong disk!
- create partition primary <- creates a primary partition taking up all space on the drive, adjust the command if necessary
- exit, exit to exit diskpart and the command prompt
- click refresh in partition manager and select your newly created partition and install to that

 

Hard disk spaced reduced after partitioning !!

hello all ,
i recently bought a 1T 64MB WD Green Cavier hard disk drive .
the problem is when i went for partitioning only 950G out of 1024G was useable! (no problem cuz i myself found out that 10% percent of all hdds space are not useable . )
but the catch is ,when i partitioned the drive with 250,200,200, 310 as partitions size
they again got reduced to 245,196,196,293 !(when i logged on to me windows) so why ? i mean the hard disk is reduced from 1 terabyte to 950 gig , so then what is the other 20Gigabyte for ?
with the current situation i can only use 930 gigabyte of my 1024 gigabyte hard drive ! and this means 94 gigabyte of space lost!! and thats crazy!*Bang Head :banghead:
how can i fix this problem ?
by the way i am using windows xp sp3
thank you in advance
