I know this drive is defective but I am running these tests to submit them to Seagate so they have an understanding of what has happened to this drive. It is a model ST31000528s.
I had been using it in a case for the purpose of backing my photo's off my notebook taken by my digital camera.
I moved 1,200 miles and made a number of stops along the way and taken hundreds of non replaceable picture's which were on this drive.
When I settled in our new place I went to copy them to my desktop computer & 4 other backup USB drives this drive showed that the directory names were all there but they were all empty. As in all GONE!
I performed all the standard MS tests and nothing was found wrong. I Tried one last trick and that was to turn the drive off and then back on. POOF There they were. All the files returned. I quickly as I could I copied them off that dive. I didn't lose one picture. What luck.
Then turned the drive off, waited a few minutes and then turned it back on an all the files were gone again.
All the directory names were still there. But no files in any directory.
So I reformatted the drive. Not the quick one. The standard format. It took 12 hours.
I ran MS diags again and again no problems showed up.
OK at this point I tried to copy some file's to the drive. I selected a t least 5 gigs worth of pictures.
6 hours later it finished. The directories were there. That's a good start. A little slow.
But every directory was blank. Not one single file was copied after 6 hours!
It's not my computer because I copied all the pictures to all the other 4 usb drives I use as backup.
And two of them are Seagate dives.
I am running SeaTools. The short DST was short and reported no errors.
The long DST has been running for hours already with nothing being reported back.
The test status shows almost half finished after many hours.
This drive see's very little use. It is only used as a backup drive. The only time it is turned on is when I copy my file's off my computer to my 5 usb drives for safety sake.
I also have the usb drives plugged into their own UPS separate from the computers UPS.
I have a Nikon DSLR and lenses & flash's and accessories and this drive is safely transported in in one of my many very well over padded camera bag's. Just in case someone thinks maybe it was banged around some while we moved.
Any ideas as to why this would happen?

It finished the long test and reported no error's.
Yesterday after I tried to copy about 10 gig's worth of data all that showed up were the directory names.
No files were in the directories. Today after running seatools which reported no error's, the FILES have mysteriously appeared.Not all of them. A lot of them. Just not all.
So I then copied some more directories in series.
C:\(dir)(dir)files to the Q:\ directory of the drive in question and they copied over.
Except they somehow wound up in the wrong directory a few directories in.
But it was shown that it was placed in a path statement of directories that aren't even on this crazy drive.
I have been servicing computer's for over 30 year's and have never seen anything like this.
This drive has very little hours on it. 386.
2 other USB Seagate drives have 8383 & 1202 hour's.
My HP computer's C drive has 12,351.
Any ideas Seaagate?

Ok, lets damage limit for now.
Get this http://www.powerdatarecovery.com/
Scan and recover, they should show up ok
Once you have the files format the drive, if you have the encrption version of Seagate Manager pull that off to the C drive before or you will lose the encryption function.
This is what I think may have happened, the software has locked the files away with the encryption even if you haven't or have mistakenly set it up to do so, assuming you have that version.
I know it's not an unlock solution, but it's the quickest and easiest way I know to get the data and start fresh which will also remove whatever did it in the first place, if this doesn't work, call back.

I have already copied off the files I needed yesterday by turning the drive off and then turning it back on.
After I had them safely on my other 4 backup drives I reformated the drive. Not that quick format, the regular format. Took about 12 hours.
Reread my first two postings it cover's everything I have done.
This is one strange drive.

Geoff please understand I do this to help out, I'm not an employee, and I sometimes only get to scan the posts, I thought you had a drive that had locked you out of your files.
Looking "quickly" again, the reason it happened was probably a connection problem, this can range from a USB port that doesn't supply enough power to the cable end being worn, as they have appeared again this is what I think has happened, in future do like I do, plug the cable into the rear MB port and hook in at the drive end, constant in and out at the usb end wears the connector and the port until you lose the 100% connection the drive requires. hth.
See there I go again, I thought it was a freeagent, but it's an external case? I would suspect this also, they aren't what you could call quality, cheap board inside with an equally cheap switch.

Too tired and have to go, try this Geoff, take it out and hook it up as a slave, do tests then put it back in and test again, compare tests and you should find the drive performs way better not wrapped up in insulating plastic, hth.

I didn't realize this was a volunteer position. So this is what I am going to do.
Give up. It's not worth it. My computer already has a drive in the second position.
It's a small capacity Seagate and for me to go through all that work, disconnecting so many wires to
get inside the pc box and risk upsetting what's working isn't worth it.
If it is a bad external case they cost close enough to a new 1tb USB drive on sale.
Now comes the big question. After reading this forum & forums at other drive manufactures
it seems these manufactures have only one goal. How do we make it cheaper.
I read a while back that Maxtor sold standard drives for PC's and a line of drives at a much higher price that were supposed to be of superior quality for mission critical application's.
Can you or anybody who reads this recommend a company that is more geared towards producing a
higher quality drive instead of a cheaper and cheaper and cheaper drive until their like what we're stuck with lately.
Thanks for your help.

It's two wires Geoff, hardly effort is it to see if it's the drive or the enclosure causing it, you don't even have to full install it, support the drive on a suitable box and work it outside of the case.
Without aiming at you, I get fed up with constant posts blaming the Seagate product when there is the slightest problem, whatever the problem is the HDD always gets the blame, it's a knee jerk reaction because 2 years ago there was a FW goof, not in your case, but how do we know it's not MB capacitors leaking or if the drive has been using a 50w Marconi original PSU or if everything is seated fully, we just don't know, all we can do is suggest and post the most common trip up's, and believe me bad data cables and connecting boards are prime candidates to make a good drive into a bad one.
Now do yourself a favour and ditch the enclosure, they're nothing but trouble, get a dock where you can simply drop the drive in and 2/3rds of it sits out in the open instead of cooking itself.
