I just read your problems.
It seems to me that your harddisk is broken.
I've a GO910 too and never discovered this problem, but sometimes I discover a read error on the disk, I'm wondering when mine will stop.
I think normaly the GO190 start from an eprom or rom (bootloader) and then want to read something from disk, but if there's no disk ...................
You see no disk with Home either with Explorer, this problem has to be solved first, normaly the GO190 is seen as an external disk.
When connected with the cradle charge only will take place when DC is connected to the cradle, otherwise the GO910 will only work with enough power in the battery.
I must somehere have a manual how to open the GO190, I think it must be somewhere at this forum too.
In case you need it, don't hesitate, just send me an e-mail at email@example.com
