Sansa e280 - partial usb connection, and freeze problems

[stew71]

Hi. I have a 8GB Sansa e280 (V1) with a 16GB card. Have run Rockbox on it for a couple of years with no problems at all. Quite recently I upgraded from 3.3 (I think) to 3.6. Initially it was fine - connected and played as usual - but a few days ago when I tried to connect to two different PCs (one XP and one Vista), I had major problems which have continued. These are:

- the device was either not picked up at all, or
- device was found, and drive letters assigned, but without any capacity and with 'unknown' file systems
- Rockbox plays ok, but freezes when I try to access any applications (I was trying to run the desktidy function when I discovered this, but it's freezing on all apps). (NB: This happened after the USB problems surfaced, so perhaps my repeated attempts to get it recognised by a PC has led to some kind of disc curruption?)
- similarly, it froze when I tried to access the build version (RB info > version) - hangup message was 'scanning disk'

The usb problem happens with both RB and the original firmware, and whether I select MSC, MTP and whether the HID is selected either 'yes' or 'no'.

I'm pretty gutted as, although it plays fine, obviously I can't use it fully nor load any different music to it. And as it was working perfectly well until a few days ago, I'm surprised that it seems to have had such a major breakdown! (Could it even be a simple cable fault?)

Any suggestions or advice will be very welcome.

Yes, filesystem corruption could easily cause this, and might well be caused by unstable connections

- similarly, it froze when I tried to access the build version (RB info > version) - hangup message was 'scanning disk'

This also points to filesystem corruption

A faulty cable is a possible (and likely) reason, yes.

OK, thanks - I'll get a new one and try it again. Presumably I'll most likely need to format it once the connection is good?
