Hi,

There are 3 questions followed by an explanation.

1) Is there a "nicer" way to enable udma/66+ speeds on the net5501 rather than 
hacking the ata driver?
2) Is the 80-wire simply broken on the net5501 or isn't udma/66+ speeds 
supported?
3) since it doesn't work "out of the box"; I have to ask if it is considered 
safe to run a SATA disk at udma/100.


In my current setup I have had to hack the driver source to always report 
80-wire in order to get ata speeds above udma/33.

Hardware:
  - net5501
  - SATA Harddisk
  - WinTV PVR-500

Software:
  - GNU/Linux (Debian)


Without the hack I get:
"limited to UDMA/33 due to 40-wire cable" and read performance at 28MB/s 
(hdparm) which is a tad too slow for my purpose.

With the hack I get:
udma/100 (max. supported) and read performance at 57MB/s (hdparm)
 From the testing I have done (a days worth) udma/100 seams pretty stable.
