I formatted it using MSWindows.  Then checked with sfdisk and fdisk and the 
same errors (of "partition 1 extends past end of disk" and physical/logical 
endings mismatch) came up.

Running parted shows no problems what-so-ever:
====================================
Model: Ut163 USB2FlashStorage (scsi)
Disk /dev/sda: 1011MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      32.3kB  1011MB  1011MB  primary  fat16        boot
====================================

Perhaps parted is more compatible with the MSDOS ways of interpreting disk 
geometry?
