USB flash drive, AVI corrupted files...

(I don't know if this's the correct forum)

Recently I dragged some AVI files (recorded by me) from my SD card to my USB flash memory. I did this in a PC. Then, I mounted the flash memory on my Mac and saved the files on my hard disk. But QT couldn't open any .AVI files because they got corrupted while transferring them (argh!).

Anyone knows of a realiable flash drive recovery or corrupted files repair software for Mac? I really need these files soon...

Excuse my poor English

Thanks

MacBook, Mac OS X (10.4.11)

Data Rescue should recover the files from the flash drive. Might also be worth seeing if the avi files work with VLC.

I am not on a Mac right now to confirm all this but some files do not play directly in Quicktime, and AVI might be one of those. Try downloading VLC which is a free player that will play many kinds of files. Alternatively there is a support package called Perian that expands the playback features of Quicktime.

Well, I'm not quite sure what kind of cards am I using. The SD card is a common one, one of those you use for digital cameras. It's a 2GB SanDisk, quite new. The flash drive is an 8GB Data Traveler...
And, yes - the AVIs are quite big (biggest one is around 700MB, and they're about 5 or 6 with 500MB)

Anyway, I'm totally sure the files are extremely corrupted because I didn't save them on a HD... I've tried in VLC, DivX... They simply wont open the files (I mean, I don't get soundless blank screens or other kind of synthom you usually read in AVI help threads). I even went to my university's media lab and one of the teachers told me that I did wrong when I transferred the files directly from the SD card to the flash drive, without saving them on a hard disk first.

The camera isn't the cause of the problems, because yesterday I've made new videos with it and I emptyed the SD card directly to my own Mac with no problems on those AVIs at all.

In addition to all this, the flash drive presented life signs at the media lab's iMac -- the archive containing the AVI files turned unrecognizable (had that icon like a black card with green "exec" letters); when we opened it on a Windows, a lot of archives appeared and their names were in constant change.

Worst of all is that I've already format the SD card twice ^_^" (I didn't know the AVIs were corrupted - I just thought I needed QT Pro). All my hopes are relying on the flash drive.

Today I've tried recovering the flash drive's files with Data Rescue and StellarPhoenix software (all of them very limited demos) but it was all useless.

Sorry for the word labyrinth; thanks for your help..

Don't worry, the files did not corrupt!!! 🙂

Sometimes, when I record an AVI file, it works on Windows Media Player and not on QuickTime.

You need to convert the AVI to an MP4 using either Videora iPod Converter (Windows) or iSquint (Mac) and then it should be playable.

Doing this has saved my butt many times 🙂 I suggest using Videora on the PC because sometimes iSquint screws up and I've never had a problem using Videora.
