Hi everybody,

i have a problem with an external firewire hard disk. The problem is a
"Delayed Write Failure" when i try to read some kind of file (DV AVI
most of the time).

The root cause of the problem is explained at
http://www.bustrace.com/products/delayedwrite.htm.

On this page there is also a little test tool that is able to
reproduce the problem. The solution is to write a filter driver that
prevents IO larger than 128Kb to reach the drive.

Is there anyone able to write a filter driver like the one described
in the link and post it to the community?


thank you.
 
Hi, I have EXACTLY the same problem. I am capturing from DV camcoder t
an external enclosure, who is also connected via firewire withou
problems (using DVIO utility). Writting to the device is OK. When I tr
to read the files I encountered the problem described by you and th
external device is disconnected. I received firmware upgrade util, bu
it is the same version like I have it on the external enclosur
(Genesys GL711FW). So, nothing to do with it. I am thinking to lowe
the UDMA factor on the HDD or to change the cable inside the box. Th
first it could be more realistic, since the writting proccess is OK
Please give a sign if you will find a solution.

Hi, this is the same chipset of my enclosure. I already tried to
change the internal cable and the problem is still present. I also
changed the firewire cable with a better cable and no luck. How can
you change the UDMA factor of the HD ? Can you send me the firmware
upgrade utility ?
