Regev – You can reset the time remaining calculations on your Paperwhite as follows:
1) Open up any book
2) Search for ;ReadingTimeReset
– include the leading semicolon, and note that it is case sensitive and there are no spaces
3) You will get 0 search results
4) Hit the back button/icon.
Your books will now show “learning reading speed”. After a bit of reading your speed, and thus time remaining, will be recalculated.
I had the same issue and found this fix on a blog:
I came across the following error message when activating Windows 8 Enterprise x64 RTM en-gb, downloaded from MSDN:
“Error 0x8007007B The File name, directory name, or volume label syntax is incorrect.”
Using the key provided to you (MSDN etc.) you will need to run the following in an elevated command prompt –
if you are new to Windows 8, click Start –> type “cmd” –> right-click on a command prompt and select “Run as administrator” in the bottom of the page:
Next type the following commands:
slmgr.vbs /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
The first command will update the key.
The second command will activate Windows.
Replace the “XXXX” bits with your Windows 8 Key (you do need to enter the dashes and you don’t need to surround it with double quotes).
Although didn’t with me as drivers were already installed.
I made sure USB debugging was on. And that MTP was on. Still nothing. So set MTP to Charging, wait for Windows to do the drive thing again. Then set back to MTP. Drivers do their thing again and there are the folders. Finally.
