I have never had a problem before using these drives with Windows 7. I have now managed to format three thumb drives with no problem. I was pressed for time before and probably did not do it correctly. They are both working OK now.
It is interesting that with ISO to USB I get the "Invalid data type for NoDriveTypeAutoRun and the program hangs. With the Windows 7 USB/DVD Download Tool I get the "selected file is not an ISO file. Select a valid ISO file and try again." I get this with both ISO files, 32 and 64 bit.
The 64 bit file is larger than the 32 bit file but in Explorer they show as 2,024,842 KB for 32 bit and 1,412,484 KB for the 64 bit. To me this seems to indicate that the 64 bit did not fully download? If the computer goes into power saving mode while the download is in progress, will this affect the download?
Is there any way to check the integrity of these files?
