in fact it seems that it depends on when you bought the sharp recorder. Until 2004, it was possible to change the harddisk because some people manage to do that. But since 2005, I think the sharp compagny changed the system and it's now impossible to do it.
If I find a sharp receiver which was built before 2005 , I can try to exchange the harddisk...
I was going to ask how to change the DVD writer, ok I still will if anyone knows just for info / reference, but the important thing here is I've just resurrected mine by using a standard cd head cleaner (cd with little brushes on).
It stopped recording ages ago, and now it records again. It is fussy about disks though.
I've also just ordered a second dvd HD recorder (JVC DR-MH30) cheap from ebay, but that's a different story, for another room and it still needs to be analogue as digital freeview reception here is rubbish.
No mate i havent got it for my dv hr300H, notice the H ,
i did do quite a bit of looking on the sharp.de site i managed to download the manual for the uk version (mine 300H)
i also looked at the software but its for the 300 S only .
I currently have the version 00000105 dated 04/01/28
so i reckon there should be some software available somewhere.
Mine by the way has been an excellent unit from new the only glitches ive had is:
occasionally wont move from pause play etc it freezes , i have to stop playing and start play agin
and on 1 occasion i had to remove all recordings though i didnt want to as it would not do anything.
PLEASE ANYONE IF YOU KNOW OF SOFTWARE ETC FOR THE 300H LET US KNOW
Thanks
