#77 "Unhandled exception" for large dump

[AntumDeluge]

I was trying to save a dump of a USB drive of around 3.2GB. Everytime I did so wxHexEditor would crash with an "Unhandled exception" dialog and I would be forced to abort.

I decided to get an idea of at what size the error occurs. I was able to successfully dump 1,000,000 sectors (512,000,000 bytes). The crash happened on my next attempt when I tried to dump 10,000,000 sectors (5,120,000,000 bytes). So somewhere between those two values wxHexEditor is having trouble.

I wonder if it has anything to do with memory available on my system.

Windows Vista 64-bit, 4GB RAM, Intel Core2-Duo T6400 2.0GHz.

Hi Antum,
wxHexEditor doesn't use system ram for storing information. So it's not related with if there is no programming error ( some function leaks memory ). So your 4GB of RAM is enough for anything. But you can watch program memory usage with task manager.

I cannot estimate what the issue is. I also cannot verify this due not usable flash disk around here with. (I think I need to buy 8GB Flash USB or SD card.)

But it might be related with multi-threaded read/write function for accelerating read/write from SSD drives.

Do you use "Devices -> Device Image Tools -> Backup" for dumping or use selection and SaveAs Dump function?

I test it under Linux for dumping 1.7GB partition multiple of times and there is no error. Also uses 45MB while copying. Cannot test it under Windows right now.
