But I forgot to change its partition Id from "b"(W95 FAT32) to "7"(HPFS/NTFS) in "fdisk". After copied the data return into this partition, I booted into Windows and did a disk scanning and repairing on this partition and no error or warning reported.

*shrug*,  I would imagine it is either working, or not working.   but
I am fairly confident that if it is working now, it will not break in
the future due to the partition ID.  Windows can take care of itself.

although I suppose having it as a 0x0b instead of a 0x07 could cause
more strain to the magnetic media...  possibly shortening it's
lifespan by 0.27 seconds.
