Hey Guys,
i found a good solution in a german board, which works just fine on each unit.
1.) You need to install a Registry Editor. If you got not the "resco explorer" you can take a freeware tool, like the
Tascal RegEdit.
2.) Go to" HKEY_LOCAL_MACHINE\System\StorageManager" and change the value of "PNPUNloadDelay" from 1500 to 4096. Now you just have to softreset your unit and everything will work fine ...
I have tried this on 3 units, and all 3 dont have any problems in this.
Description: This key says WM5 how often the SD-Driver has to reload the SD-Card, if the unit is in stand-by mode. From now on this is not 1500, but 4096ms. As you know this issue just appears with sd cards plugged in.
i hope that it will fix your problems, too.
