Flash Savior
Posted by Eric on 26 April 2001, 18:25 GMT

From the depths of France comes yet another interesting idea for the TI-89 and TI-92+: an aptly-named Flash Savior! If you're an astute one, you might guess that this program saves deleted files from your FLASH ROM. Yup. By running this program you can now recover programs that were lost due to erasure or calculator crashes. Perhaps this will help encourage use of the FLASH memory...in any case, a nice achievement by Julien Monville and Thibaut Barthélemy. Thanks to tinews.net for the heads-up.

Doesn't the current AMS software also do that after a crash? Mine's been pretty stable after I stopped playing games on it and it's been so long since it crashed I can't quite remember.

Did'nt you read TI documentation ? :)
When an archived file is erased, he is infact only marked by suppression, so you may recover all the archived files you deleted since the last garbage collection.
It's also quite explained, but of course in our good old deep french ;)
It must work just like AU3 as well (this "Archive Utility 3"'s option was not included in new AMS 2.0X)

This isn't a new idea. Archive Utility 3.0 had this feature (although it was very buggy). On that note, if anyone still has Archive Utility 2.0 I'd be VERY happy. If you have it, email it to me. I'd love to go back to AMS 1.0 where the teachers can't erase all my memory :)

Have you a TI89 ?
I tried many times to go back to AMS 1.00, but never succesful, even if there was no problem with going back to AMS 1.05 or older... (???)
Maybe with tibreceiver ?
Nevertheless, 2.05 seems to be stable as well. :)

TIB receiver does not work with AMS versions. HW2 calcs can NOT go back to AMS 1.00, they can only go back to AMS 1.05.

There is also a program like this for 83+ MirageOS called Archive Recover. It's small and works pretty nicely too, although most of the time TIOS recovers archived data after a crash.

no mem reset?

How will AMS 1.0 not keep stuff from being erased?

This program (not surprisingly) doesn't work with AMS 2.05. Unfortunately, I somehow lost ALL my memory yesterday when I used TiLP 4.17 to transfer the Euchre game to my calculator. 17 days worth of programming was lost, and that's a LOT of work for me (about 20-30 programs). Needless to say I was displeased that my AMS version was incompatible... but life goes on, I suppose.

This prog doesn't work for me. BTW how possibly can you recover deleted files? Or they aren't actually deleted?

Flash memory has a limited number of writes. Any given block of memory may only be written to about 100,000 times. In order to keep this from being a problem, systems using Flash store files sequentially. Any deleted file is simply marked as deleted. Once the entire user space is filled, the system will go back and reorganize the flash memory ("garbage collection"). At this point, all deleted files will be removed and the free space will be grouped together. So, if you unmark the file, it can be used again instead of being deleted.

More than likely than not, however, you will either wear out or replace your calculator long before you've written to FLASH 100,000 times.

Hi !

Sorry for that :(
Normaly, FlashSavior is supposed to work on all AMS...(I have currently AMS 2.05, and it works fine...)
But FlashSavior is an assembly program, and it's the first public version, so it's surely not bugfree :(

I'm not sure to understand what hapened to you. Could you be more precise ?
In fact, I don't undersand what TiLP can have done in this problem...

In any case, if you haven't performed a garbage collection since the crash (and if your files were in Archive Memory),
DUMP YOUR ROM WITH THE WIZARD OF VTI, and send it to me by e-mail (asm_dev@voonoo.net).
I will try to recover your files anyway, but don't hope to much ;)
(just lord_nightrose, not the others if there are any, I won't have the time for fifty persons)


Thibaut and I will do an update soon, with litle bug correction, and we will make an English readme in tis version :)

have a nice day :)
Julien MONVILLE


P.S.
don't forget that you must launch FlashSavior a first time to make a backup named FlashBak!

Flash Savior doesn't work

Flash Savior crashes my HW2 AMS v1.05 calc whenever I try to run it...what's wrong?

Get AMS 2.0x and itll work fine. 1.05 dosent use flash rom.

Re: Re: Flash Savior doesn't work

Oh yeah, I forgot about that, probably cause I used to have 2.0x on my old calc (the one that got lost). Thanx!

good point Derek... seeing how all AMS versions are on TI-89s with Flash memory built-in. Of COURSE 1.05 uses Flash.

Doi...

Hey great program!! Finally something like this that can work on ams 2.0x. I found a bug though. I have a hw1 2.03 calc and when flashsavior gets to folder main, it crashes. If you need it, I'll send a list of the programs in the main folder. Its not the first file, because I tried moving it.
