Please read this, I know what is wrong....

I have the same problem with file saves and a ticket they have not responded. Not sure they have a clue concerning the cause. I worked by myself to try and solve it.

There is a "Bundle" and a "Preset" save error problem. If you save the file into the proper bundle or preset folder all seems to be fine BUT when you try and reload the file "data corruption error" and all presets lost and changed to "new tone". Your data is NOT lost!! Please read the following on how to get around the bug.

Been there and done that, still no reponse from Line 6, I can only assume it is a major software flaw someone would like to ignore or perhaps hope the teenagers will never use the feature to find it does not work.

UPSIDE;

Your files are still intact, do not delete them! IT IS NOT THE POD it is a software problem!!! A new unit will not fix it.

Go find the file outside the editor software and open it, the editor will come up with the presets you saved, you can resend them back into the unit. DO NOT open the editor first and try and load up the 'bundle" or "preset" file IT WILL NOT WORK!

Open the file by locating the POD folder where they are stored, something like  C:user/-name-/documents/line6/hdpod/

A.) To keep the POD from sending all its bad content into the editor, open the editor first before you plug in the USB. It will ask you to bring in the POD data, say NO.

B.) Select the preset file you opened by itself and resend it back into the POD.

C.) File save for presets suffers no problems, be sure and save each preset as you design it into the basic POD directory folder. Whenever I edit a preset I "send" it back into the POD memory.

D.) Make sure you have all your presets saved in the basic folder to resend them back into the POD as each software update will replace everything back to factory.

E.) The Bundle and Preset files are still intact just find them and open them without using the main editor software page. A new editor window will open containing your data.

Unfortunately, I dont have a solution to your problem, but I experienced it a few days ago and made it out ....though there were a few after-effects so to speak....

I created a topic here http://line6.com/support/thread/85066?tstart=0  to explain what happened to my HD and happened upon your post just after that.

I'm glad (if I may say so) to see I'm not the only one experiencing this sort of thing and hope Line6 will solve the problem speedily.

not going to solve the problem, but whatever,... been 2 weeks already since you posted your question and marked it as such ....and no one from Line6's even posted anything to try and help you....speaks volume about the relevance of this board and its staff.

Does anyone know if they even read or take into account the tweak and fixes we put forth to fix the unit, or are we wasting our time?

I complained to LINE 6 that not saying anything in regard to issues or improvement suggestions is not going well for them. They never mention, "hey we are working on this or plan to do this or add that on the next update". If I wait 6mos in a blind vaccum hoping they fix some minor things and come to find out they were never planning to do so. That will end my use of Line 6 equipment and the end of decent reviews regarding them. If they wish to appeal and market to teenage level players then they will never be taken seriously by advanced players. Does not matter of the unit has so much more capability than the average dufus understands is in there, those of use who need it and use it will be the ones to defend the unit to purists who hate modeling. 

I need that bloody Pitch Glide controller editor param to be intervals not percentage and if that does not happen or at least I get a comment that it is being worked on, that new Whammy pedal is looking better all the time. My Wampler compressor and others have already nulled many of the internal effect models. Now it is down to some of the modulations, delays and reverbs holding my attention. Line 6 needs to tell us what is going on and what is planned. The acute lack of respect and caring is what loses long term customers, you know the ones of us that have played for decades who buy large amounts of gear. Most of the purists on the web sites hate Line 6 model attempts. I get the best out of them and quite like the amp models but I need my effects and good ones. Something is not right with the effects loop as well, just not transparent to what you run into it. It needs to be improved as well.

If they do not wish or do not plan to fix various things or plan some new amp models, would it kill them to mention something???? Really bad PR and customer apeasement.
