Well, I got my 3 Clickfree 1TB C2 Drives the other day and plugged the first one into my wife's old XP Professional PC, and it appeared to fire right up like it was going to start the backup, but then stopped, and another window overlayed the original one asking if I wanted to perform a software update...
But of course I do, so I hit the OK button, and it very quickly downloaded the software to her PC to install, but then failed during the update. (Bummer...)
That was all she wrote. The Drive could be recognized on that machine and others, but would never begin the Automatic Backup.
Being the technical type, I searched the Clickfree Web Site for a software download to run it again manually, but could not find one anywhere.
Fortunately, the online Chat Box on the Clickfree Web Site was handy, so I used it to get in touch with a Tech that quickly evaluated the problem, and emailed me a link to download the latest software.
I followed the instructions in the email to the letter which included logging into their host server and downloading the software (about 40 Mbytes.)
Once I executed the file, the update began to run and it successfully updated the drive.
After the update completes, the instructions tell you to
(1) "Shutdown and Power Off the PC Normally"
(2) Unplug the Clickfree Drive from the PC
(3) Reboot the PC and let it go through all of its normal Startup routine to come up fully
(4) Plug In and Connect the Clickfree C2 Drive.
Once connected, after about 60 seconds, the Clickfree Backup Screen popped up and she started the backup just fine.
This was an old PC with only USB 1.1 ports on it, and it backed up just fine, albeit very slowly as expected. It backed up about 60,000 files (about 50Gbytes), but took about 18 hours to do it, so very painful time wise, however the best part was that there was virtually NO LOAD on the Single 1.6Ghz AMD CPU during the whole process, so you could just continue doing other stuff without any interruptions which was a Plus.
Just to let you know, I had performed the software update of this device while it was connected to another PC with USB 2.0 ports, and someday if I get another PC, I'll have to be sure to get 3.0 ports to take full advantage of the full speed capabilities of this 1 TB Clickfree C2 drive.
I'm guessing I'll have to update the other two drives I purchased as well, but since I have the software downloaded already, it should be a pretty easy fix if the online update fails.
I'm a happy camper with my little drive and recommend it highly.
Now off to the bank's safe deposit box with my backup drive until next month when I'll retrieve it and update the existing backup.
Here in Florida, with Hurricanes and all, I like to keep multiple backup copies of our family pictures, etc just in case....
Good luck with yours!
