D drive partition on ACER Nitro not working and unable to format

rheanna

Can anyone help i bought an acer laptop and the c drive and programes work great but the storage part 'D Drive' says it canot be used as it needs formatting. It gives you an option to format but when i have tried to format it it doesn't work. so i now have a very expensive laptop that i can't put my stuff on as the D drive is 913GB and not useable. Any suggestions?

Thanks.

Are you doing this in Disk Management? Control Panal/Administrative tools/Computer Management/Disk Management

Does it say it's a (D) 913GB NTFS  (Healthy Primary Partition)?

C drive is NTFS, but the d drive says RAW. it says its healthy primary partition but I can't use it. It asks for formatting to be able to use but won't format when I try. Thanks.

Note the sizes of all the drives.

Open a command prompt as Administrator.

Type diskpart

 Then type list disk     find the drive. Be absolutely sure it's the correct drive

type select disk * (the number of the drive)

Type clean

type create partition primary

type format fs=ntfs quick

Type exit   

again type exit

Thanks, I got as far as Diskpart clean and got this message

Diskpart has encountered an error: The request could not be performed because of an I/O device error.

Download and run Malwarebytes https://www.malwarebytes.org/mwb-download/

After it's done, Open a command prompt as Administrator.

Run chkdsk c: /r   Then try diskpart. 

If it still gives you an error boot into safe mode and run diskpart.
