Thanks Ken. Yes I agree with getting the problem fixed under warranty.
Having discovered the Diagnostics menu you pointed out, and being technical in nature, I have been working through the menu.
A few observations:
1. The key press responses tend to be sluggish!
2. Test 4 - SD Card passes test 4.1. Test 4.2 seems to need some external program. Where can I get that from?
3. Test 6 wants a file copied. usb.bin Any idea where I can get this from?
4. Test 12 I would LOVE to do - Whole USB Test. Again I think it needs external software. Any idea where I can get that from?
5. Test 14 is simple memory check. 14.1 test SD RAM. This passed. 14.2 tests NOR flash checksum. This passed too. 14.3 tests NAND Flash checksum. This has two: mtd3 passed, but mtd4 FAILED (has a X). then it just sits there and doesn't respond to ANY keys (even the green LED is off) and I have to press RESET to get out.
Is there something that this indicates?
Would re-flashing something sort any of this out?
If I could sort this out WITHOUT having to pay Fed-Ex a fortune to ship to and fro between the US and South Africa, I would be glad to try it!!!
One more observation: After performing the Restore to Factory Defaults, yes, my mtd6 was formatted, thus erasing my Internal Memory. So I booted the Jetbook, and the went to the "charging" screen (the USB cable was connected during bootup) but DID mount (only) the Internal Memory. (The SD Card was blanked by me last night.) In this state I copied my backed up contents of that drive to the Jetbook's Internal Memory in one drag and drop operation. No errors. I did an "Eject" and the data flushed to the Jetbook.
So I tried to format the SD Card - the 16GB - (from my Linux PC, with the SD Card in the Jetbook). I mean, if it can write 50MB to the Internal Memory OK, then surely it should manage a few kilobytes for the FAT table during a format. But alas:

So sadly the Reset didn't work for the SD Card. BTW, the SD Card is formatted WITHOUT a partition table - i.e. the whole device is formatted. I have tried writing a partition table to it and formatting that, but it had made no difference.
Again, thanks for the input.
