    if you mean, the drive appears  as normal, but you try and alter its LABEL and it wont let you, then its probably a security issue and only mounted with READ only attributes. This could also be a drive FAULT. 

    If this is a different PC altogether then your USERname which your FORMATTED the drive with, applied its security credentials to whatever folders you created at the time. 

     If this different OS which must have different USERnames is then used it could cause such issues. If the drive were formatted FAT32 instead which has no security credentials because its not NTFS then it should work in anything.

    You might fool it by creating a USERname EXACTLY the same as when it was formatted, and logging on as that user to access it from W7.

    You could dabble with CHANGE OWNERSHIP to everyone on the pc it works in.

    If what you did was REVERT a windows 10 PC back to W7 because you didnt like W10 then try the USERname mod.

    If you formatted it for other OS's so its not NTFS or FAT32 then W7 might be able to mount the drive as READ ONLY for that reason.

    So NOT all Filing Systems(NTFS/FAT32/ExFAT etc) are supported by windows but some might be for read only.

    Check in Disk Management what the pc thinks it has in there as far as Filing Systems go.

    Chances are the drive requires a driver not loaded in Windows 7 which is loaded automatically in Windows 10.  I would also check the original machine this was configured on as to what format the drive partitions may be formatted.

    likely cause is a partition type not supported by Win 7
