[SOLVED] External HDD shows incorrect capacity

[ma001uk]

Hi, I have external HDD Samsung HM160HC SATA in a closure. I connect it to PC using USB port. Somehow I have formatted it to 32Gb . I have tried to format to get full capacity of 160Gb without success. I have deleted partitions, created new partitions in HTFS but still capacity does not change. I have EASEUS partition master free which I have been using.
I have looked online for tools but nothing seems to help me.
Thank you.

You have to delete the volume, not just the partitions.
Reformat as NTFS.

Can you show us your partitions with DMDE?

I have it connected to another laptop. How do i delete the volume.

 

[ma001uk]

I have installed DMDE and running it. Table for the external HDD disk says... logic.disk , ntfs ... 33.8gb ... BCF .. first sector 0 last sector 66027086.
I am not sure how to show table to you ?

 

[ma001uk]

ps .. only one partition on the drive.

In Disk Management.

It was probably somehow just formatted to FAT32.

I have deleted volume .. still shows free space as 31.5GB. It says disk 1 , basic, online in disk management.

Right click .. menu shows new simple volume , delete partition as options.

How do I create partition and format to 160GB.

 

[USAFRet]

DELETE Partition

Then, what right click options does it give?

 

[ma001uk]

I have deleted partition. Options on right click now are .. new simple volume, properties.

 

[USAFRet]

New Simple Volume
Then it should give you the option to Format. Select NTFS
Then, give it a drive letter.

 

[ma001uk]

Selected new simple volume, Specify Volume size shows max disc space 32.25Gb. simple vol size same. no NTFS option here.

 

[USAFRet]

I should have just said this from the beginning.

cmd or powershell:

Diskpart

list disk
select disk * (where * is the actual drive you want to work with)
clean all
create partition
format NTFS
assign letter=d (or whatever drive letter you want. Not A or B, please)

 

[ma001uk]

hi.. clean all running at present. Taking lot of time. I will let you know if successful . Bye for now and thanks for help.

Hi .. I have tried as suggested in powershell using DISKPART.

No luck. Still shows 31GB when I have formatted in NTFS. I set primary single partition.

I downloaded testdisk to check structure of disk.

It shows CHS as 4111, 140 , 61 . This equates to 32gb.
Size in sector is shown as 66050048.

Do I need to change CHS settings to get full capacity. I am new to this and dont want to do something that totally messes up the disk.

What total capacity is reported by CrystalDiskInfo?

BTW, DMDE reports the total capacity on the first line at the top of the window. Individual partition capacities are reported next to each partition/volume.

 

[ma001uk]

I have downloaded crystaldisk and installed. Does not recognize the disk connected to USB. Only show info on internal disk.

DMDE shows primary partition, NTFS(07), 33.8gb, Indicators EBCF, first sector 2048, last sector 66052095.

What is BTW ?

 

[fzabkar]

BTW = by the way

It's a hangover from my Usenet days. Sorry.

I'm trying to determine whether your drive's capacity has somehow been reduced via a HPA (Host Protected Area). The DMDE information that you have reported is the info for a particular partition. We want the info for the entire drive.

For example …

In the Partitions window we see "Drive 0 - 932GiB", first sector = 0, last sector = 1953525167. That's the entire drive.

Further down, we see the individual partitions, eg Basic data partition, first sector = 2048, last sector = 1023999.

Do you understand now?

Hi
I have looked at partitions in DMDE . It show one partition only.
It says on lines :
line 1 - Drive 1 - 31.5GiB USB , Primary F. system MBR , size 31.5GiB ,
indicator T , first sector 0, last sector 66 055 243
line 2 - partition Primary, f. System NTFS (07), size 31.5GiB, indicators
EBCF, first sector 2048, last sector 66 052 095

No other partitions.

It looks like the drive has been truncated with a HPA.

I would remove the drive from its enclosure, attach it to a SATA port in your computer, and restore its full, native capacity with a tool such as HDAT2 (DOS), MHDD or SeaTools. There is also the HDD Capacity Restore Tool.
