    An "unallocated" hard drive means that it does not have a recognized file system on it - e.g. a Window FAT or NTFS partition.

    Presumably you had a partition (a drive letter) full of data an now the partition has disappeared and you want to get the data back? (if this is not the case and you just have a blank drive, then all you need to do is use Windows Disk Management to create a new partition and then format it).

    There are tools online that will try and "fix" an unallocated drive. Be warned! These tools write to the drive and try and fix the problem - if they don't work, writing to the problem drive can make subsequent data recovery attempts more difficult.

    The best methodology is to have the problem unallocated drive connected to a computer as the secondary drive. Download Recover My Files from Data Recovery Software to Undelete Files; Disk recovery; Recover Deleted Files and run a "Recover Drive" search on the drive letter in automatic mode (there is a video in the first sticky post of this forum which will show you and example of a drive recovery).

    Once you have located all the files, if they preview in the search results screen and you are happy that you have found them, then purchase a key and save the files to another drive. Make sure you don't write any new data to the problem drive until you are sure that you have all the files that you need saved.

    Once you are confident that you have saved your important data and have tested the files to make sure they open ok, then you can format the unallocated disk, create a new partition, format it and copy the files back.

    Good luck.
