When you connected the USB drive to PC and used Diskpart to check information about the disk, you were able to correctly select the USB drive. But when you type detail disk in Diskpart, there is an error message stating: there are no volumes.
Why is this happening? And why is the volume not showing up in Diskpart? Well, you need to make sure that your external drive connected to the computer is recognized by it. If the external storage device is not recognized by the system, then you cannot use it to perform any operation. That is why when you type detail disk in Diskpart, you get the error message: ‘Diskpart list volume there are no volumes’. Windows can recognize the usual FAT, NTFS file systems. If you create a volume with any other file system and try to check the detail disk information in Diskpart, then you would get a Diskpart error.
So how to fix Diskpart is missing volume error?
To fix the error, you need to format the drive with FAT32 or NTFS. This is the only way by which you can fix the error message. But make sure to backup data before formatting the drive. Else you end up losing important files present in the external storage device. There are also many tools available online which help to change the file system of the external hard drive and format it to NTFS or FAT32.
So once you get the partition with FAT32 or NTFS, the error message will get fixed. Now you can check the detail information of the disk, and continue with any operation. Suppose you have not backed up files and ended up losing data after format operation, then you can make use of Partition Recovery tool to restore your data.
Also, if you have accidentally deleted a partition, or it is lost, you can restore it efficiently. Moreover, you can recover deleted volume, lost volume, data from hard drive after the crash, files from the RAW or inaccessible partition, and so on. In just a short span of time, all your data will be recovered in few simple steps.
