are loop/msdos drivers writable?

With the write blocksize, I can read a dosemu virtual hard disk
with loop... But when I try to write a file I got:
pr 9 22:37:22 compaq kernel: Adding Swap: 36252k swap-space
Apr 10 01:37:43 compaq kernel: attempt to access beyond end of device
Apr 10 01:37:43 compaq kernel: 07:00: rw=0, want=222, limit=221

Apr 10 01:37:43 compaq kernel: attempt to access beyond end of device
syslog line 5789/6012 96%

and I paniced badly and then had to hard boot.

Possibly the virtual hard disk is not necessarily full size...
