Unbelievably slow transfer rate to iRiver media player

BigGeoff · 04-07-2010, 12:25 PM

I recently purchased an iRiver P7 media player which I am using with Rhythmbox under Ubuntu 9.04. The transfer speed when uploading files to the player is phenomenally slow - the first 50 or so MB reported virtually instantly then the speed immediately drops to about 12-15KB/sec yes KB/sec so a 3-400MB video file takes hours to transfer to the player. This happens with the internal memory and the added memory (SD card) too, althoufg it is faster ror the SD card. No other devices have ever behaved like this on this system (and I have used 2 different Creative players, a different iRiver player and numerous memory sticks). The computer is dual booting with windows (for once that was useful) and under windows it doesn't happen, the speed is as expected so it isn't the hardware. I don't want to have to resort to damned windoze just for this.

dmesg after plugging in the player shows it identifying both the internal storage and the added SD card but I don't understand the rest of it:

This last message gets repeated lots of times, and during transfers it seems to be issued continuously and I suppose this is why the system is so slow because it is always retrying loads of times before a success.

Could someone please dig me out of this? I have found a number of similar threads including one or two on the ubuntu forum but no real solution.

Thanks

Does this work with other computers (and/or operating systems)?

Just trying to figure out whether this is a problem with the computer or the iRiver.

BigGeoff · 04-16-2010, 01:31 PM

Yes Skykooler it works fine with several PCs at work (windows) and it even works with this computer if I boot into Vista (I forgot to mention this is a Dell XPS710) but obviously I don't want to boot into windows - it's only on there so the wife can run some rather specialist apps for work. So that really rules out the hardware.

I also noted that in fact when you copy to the SD card as opposed to the built in flash, although it is slow, it is considerably faster, in fact almost usable. Almost. But that doesn't solve the real problem and wastes 16GB of flash.
