Hey, my TI 89 is not archiving my 32778 large file, it says could not archive: memory, but when i look at how much free flash rom I have it is 192750, which is a lot more than the file big is, so why can't it archive it?

EDIT: I'm having another issue: With this one asm prog it is giving me error mem even thought it used to work when I had less free ram than I have right now. Could it be that the os thinks that my memory is lower?
Should I reset all?

Reset all and check the OS and send the newest one (even if you already have it on the calc)

Trust me, it's probably the best solution

I am getting now sooner the error mem with flash

I just read that flash could wear out, is it wearing out on my 89 (i bought it used)

* Sorunome hopes that not, i don't wanne restart playing links awakening

You need to do a factory reset, then... I believe that's how you reset flash page rewrites

How do you factory reset the calc?

The flash chip is unlikely to be worn out. The TI-89 AMS operating system is smarter than the TI-83+ EOS. It avoid unnecessary un/archiving. It's more likely to be a corruption issue, but I sadly can't really help you with fixing that. The TI-89 platform doesn't have (to my knowledge) a program like MicrOS that could be used to identify and fix the corrupted data.

What about just rebooting the calculator (2nd + LEFT + RIGHT + ON), after transferring all important data (since you cannot archive it), assuming the calculator's OS state is not corrupted enough for transfers not to work ?

Resetting all memory and transferring the OS anew might be a bit of a heavy-handed hammer for something that might well be solved by a reboot

And indeed, the Flash chip is extremely unlikely to be worn out.

I think it takes like 200000-10000000 rewrites before wearing out, right?

Lionel Debroux · « **Reply #8 on:** March 07, 2013, 01:37:58 am »

A bit less than that, good Flash memory chips are often rated for ~100K erase cycles for a given sector.
For a general sector, even with 3 daily erase + rewrite cycles (very heavy usage), reaching 100K cycles takes 30000+ days, i.e. more than three quarters of a century.
The single garbage collection sector gets more erase + rewrite cycles than the others do, but even then, the calculator will break in all kinds of other ways before the Flash memory wears out

DJ Omnimaga · « **Reply #9 on:** March 07, 2013, 01:53:51 am »

Indeed. I think the only way it could happen faster is if someone decided to waste his calc, replace batteries with a power adapter then let an archive sector rewriting program run non-stop until the flash (or something else in the calc) dies.

Or maybe defective flash? (Like what was suspected with Drummist's 83+)

Don't reset it. You might just have to garbage collect archive.

Lionel Debroux · « **Reply #11 on:** March 07, 2013, 03:32:30 am »

Garbage collection is supposed to occur automatically when needed.

pimathbrainiac · « **Reply #12 on:** March 07, 2013, 09:55:20 am »

You can still force a garbage collect on the 89 (I think it might require a 3rd party program, but I can't check if you can do it without 3rd party software...)

On an unrelated note: 500th post!!! (only 12 more until a nice round number...)

Sure, by using the EM_GC() ROM_CALL, through an ASM program or Exec string. But that's very seldom necessary, as GC occurs when needed

Sorunome · « **Reply #14 on:** March 07, 2013, 07:29:22 pm »

I think that GC didn't occur when needed as I did the os thing before all of your other posts and that bug is now a lot sooner already (and yes, linking is still working)
I'll try 2nd+left+right+on next

EDIT: that didn't fix it

* Sorunome gets a program to manually garbage collect

EDIT2: Nope, the one i tried isn't fixing it
