I recently did my un-regular-regular check with the Diagnostictool on my FAP 750 and it told me a diagnostic code, so I called the service and they said, its better to send in.
Of course it's not that easy to backup the backup but well I had to because it contains important backups from different client pc's So I bought a new FAP 750, so I copied the old contents to the new disk this night.
And now I deleted all the **bleep** on the old one, low-level-formatted it, and rechecked with the diagnostic tools
AND GUESS WHAT?!?!?!
The OLD drive is now fully working again and the NEW drive has now a diagnostic code
and I did recheck that the serials are not the same so I didnt accidently check the wrong one
So either the Diagnostic tool doesnt work with a FAP 750 when full to the limit or something is seriously broken.
EDIT: So i cleared now some data from the new drive, and no code anymore on both drives But I noticed that if I only plug the new drive in the Bootup is faster because it gets recognized faster With the old one it takes always a few seconds more the Booup as the Detection takes ages. Maybe I should send it in? I don't have a diagnostic code anymore but oh well Maybe they can find something?
