[DATA EXPUNGED?]: Corrupt Groups?
« on: March 22, 2010, 07:34:10 am »
So, for some godforsaken reason, my calculator is being a data whore.
When I extract ANY of my groups, I always end up with a program with no data. (16 bytes)
When I delete it, it RAM clears me.
I hope I didn't lose my files.

Any ideas on why this may happen?

Mhmm this is interesting. I think the only way to fix it is to try sending the groups on the computer or another calc, archive everything if applicable then try ungrouping and see what happens. if your groups are fine, then your calc needs a fresh memory reset (RAM and Archive), or maybe even an OS reinstall. If you reach the point where you have to reinstall the OS, then attempt making new groups afterward, and they can't ungroup fine, or if your current groups ungroup fine on other calcs and not yours, then I am afraid your calc might be bricked x.x

Try using Brandon Wilson's group tool to only ungroup what you need, and to group it to ROM.  Then, reset your RAM.  Delete the old group and re-group it all.  That's what I do with a corrupt group.

Oh wait forgot about that one, that could maybe work too.

Btw, does CelticIII has group/ungroup support? Maybe that could be another option

Yeah, I think that Celtic III has support for groups.

Celtic III does *not* handle corrupted groups. A poor workaround: don't index the grouped items; just start extracting them item by item, checking each item after each extraction for its integrity. Once you've found the corrupt entry, clear your RAM then ungroup what you were able to successful extract. Back that up and then try to look for other methods of recovering that data. I'm sorry, but I can't think of any other way to deal with something like that.

I've had this happen to me a couple of times before. Thankfully, I've had other backups I could fall back on.

Sorry to hear this. Best of luck to you.

Group corrupting is too much common. :( Bad TI.
GroupTool is quite useful. The only problem is it can be slow seeing large groups.

Yes it does. It opens all the programs and I don't remember if lets you edit other kind of variables.

I found something:

It's also been reported that in large enough groups, the calculator may change a bit in the data when ungrouping — in practice, this might result in an error when running the newly-ungrouped program. To be on the safe side, you should check that a group "works" before deleting the original files. It's also possible that splitting the large group in two (if this is feasible) will fix the issue.
I had this happen on OS 1.12 through 1.14. Mana Force came out with a slightly corrupted program once ungrouped in earlier versions once, causing me to have to re-release the game. However, I did not know this still happened in newer OS versions (given TIBD started in 2006, by then most people were probably using 1.18 or later)

On a related note: have you also been plagued by those ERR:VERSION errors in programs and groups? I think I must have fixed those version bytes a kajillion times at school for people who couldn't transfer their favorite game to their friend. ('Where's Matthias gone? URGENT!!' Gaahhh...)

I haven't got a clue how those version bytes got changed, though. Anyone?

Yeah I got those a lot. Very annoying, and back then I lost many game progress due to this. When I grouped stuff to backup, I always created two groups, in case.

Fortunately this bug went away in OS 1.18

Oh... Then it must somehow have reappeared in OS 2.43 and 2.40. I've seen the problems there as well. Maybe 1.18 was an exception in the series.

I also heard people talking about BAD ADDRESS too. What I think is that 1.18 fixed it on 83+ calcs (and fixed the ability to group archived files on 83+SE), but these bugs were either not fully fixed for 84+ calcs or re-appeared later.

(Is it me or does sometimes TI reminds me of both Microsoft and Jester Interactive when it comes to software bugs?)

I don't remember having those errors.

But most of the groups are made on my calc or from recent downloads...

If you don't mind spending a few hours with your calculator, I would advise getting Brandon Wilson's flavour of CalcUtil (the one that supports Flash editing) and trying to manually fix your groups.  However, be careful what you do with the Flash, cause you can seriously screw up your calculator if you aren't careful.
