I have tried various cases, and here are the results:
I have Seagate Expansion 1TB External Hard Drive that i bought few years ago, and Seagate Backup Plus 3TB External Hard Drive that i bought recently. I'll just call them "Exp" and "BP" for short.
On Exp, Analyze is fully functional. No problem.
On BP, I tried analyzing the existing 1.5 TB volume; it failed.
I created a new volume of 100 GB; analyze failed.
My laptop is 500 GB with about 100 GB free space, and analyze has no problem. (I bought the laptop in Feb 2011)
All of the devices tested were NTFS, and under Windows 7 Home Premium x64. Some drives had some files and folders, other volumes were completely free space.
Bottom line is that this new external hard drive, and probably other newly sold hard drives, are having issues with Defraggler. (Maybe other way around) As you may have noticed, for BP, no matter how big or small the volume/partition was, analyze failed all the time. The only issue i can guess that would cause this problem is USB 3.0 driver, but my laptop didn't have USB 3.0 available back then, so this may be an issue rising from USB 2.0 backward compatibility, or whatever the new driver that comes with new hard drives is not compatible with Windows 7, Windows 8, Defraggler, or whatever else.
It's been about a month since last time i posted, and this topic has been on for quite a time, and yet no prompt response has been given. From a Piriform fan, it's very disappointing.
