df supllied with CYGWIN B20.1

[colin]

Dear Sir/Madam,

Hello, the df.exe supllied with CYGWINB20.1 doesn't work for
multiple disks. For example:

"df //a " fails by reporting wrongly the details for c:

df.exe seems to only give c: details and never otehr partitions.
Does df.exe work for FAT16, FAT32 and NTFS??? It seems to work for
FAT16 and NTFS but haven't checked FAT32 yet., Bye
