This is a very common problem on teh hp rx1955. There is a HUGE THREAD at the official hp support forums dealing with this. HP says they will release an update "anytime now" for the device.
The is NOT a problem w/ teh HP hx2495, and i'd assume the same goes for the hx2795.
So on HP's line of WM5, only the rx1955 is affected.
However, both devices have the WiFi stays on/battery drain issue.

that's the thread i was talking about.
When I contacted HP Support, they gave me the number to their Engineering team and I've been in talks with Jon HasACrazyLastName (lol).
Anyway, the SD Card problem DOES NOT EXIST IF YOU DO NOT CREATE AN ACTIVE SYNC PARTNERSHIP! I tested this for him by hard resetting and not sync/connecting to the computer, and I no longer experienced the issue. I have not simply tried deleting the partner ship, so i don't knwo if that'll work.
The only issue the hx2000 line of WM5 devices is the battery drain problem. There is no can't turn on device problem and there is no "disappearing" sd/cf problem, just the battery drain issue that I think is apperant in all WM5 devices. But who knows.
