#28 UDF and DVDRAM


I compiled my kernel (2.4.22) with UDF support (as
module) and with write support to use my DVDRAM device.

I mounted DVDRAM unit with
mount -t udf /dev/sdc1 /dvdram

and I obtain the followinf messages (from dmesg):

UDF-fs DEBUG lowlevel.c:57:udf_get_last_session: XA

UDF-fs INFO UDF 0.9.6-rw (2002/03/11) Mounting volume
'RAMUDF20', timestamp 2003/10/21 22:11 (103c)

When I write a new file ("prova.txt")I obtain:

udf: unknown compression code (254) stri=my test(1).txt
UDF-fs DEBUG unicode.c:414:udf_get_filename: Failed in
udf_get_filename: sname = my test(1).txt

where "my test(1).txt" is a filename written under
Windows (DVDRAM disc is formatted under Windows with
UDF 2.0).

The file "prova.txt" is correctly written under Linux
but I can't see the file written under Windows: the
problem is in special characters presents in filename,
as spaces and/or ()?

Thanks in advance
