I've just updated my client to the latest version (Home Edition v3.0.1026.7) and have been experiencing sporadic cases where my uploaded files appear to have been corrupted.
I am running Windows XP, SP3 and have been using SmartFTP for the exact same transfer operations for more than a year. My transfer involves connecting to a corporate LAN via a VPN (via CheckPoin VPN-1 SecureClient). I then FTP a set of folders each of which contains multiple files to a server on the corporate network. Typically, I just select all of the folders and transfer them, allowing SmartFTP to determine whether they have changed and therefore whether they need to be uploaded or not. The folders contain a mix of file types, some of which are ASCII text files and some of which are binarys (graphics, FrameMaker source files and PDFs).
Last night, I transferred the files and the transfer claimed to complete normally. Today, I was informed that someone received an error when attempting to access a file. I connected to the VPN and used SmartFTP to download a copy of the file to my local drive. When I attempted to access the file, I also received an error that the file was corrupted (it was a PDF file). I then tried to upload the original file to the same file location. SmartFTP's transfer queue showed that the file went through pre-transfer but no actual copy was done, suggesting the files were believed to be identical. I then did a local binary file compare of the corrupted file and the original source file on my local drive which I had just tried to upload - they had a difference in content.
I deleted the remote file and transferred it again using SmartFTP, from scratch. The transfer proceeded normally. Once complete, I download that file back to my local drive and verified that it was now intact and correct.
I then downloaded all of the remaining files I had transferred the previous night and found that almost all of them were corrupted. The exceptions appeared to be new files I had copied - any files which had previously existed and which I expected to have been replaced seemed to have been corrupted.
I remove all of the remote files and re-uploaded them. Then I downloaded them to a local drive area and verified they were now intact and correct.
Since the problem is sporadic, and the most recent transfers all worked correctly, I have not included any logs here. If the problem recurs, I will attempt to capture the logs and post them, but I am hoping there may be enough info here for you to offer some suggestions or insights. Please feel free to contact me if there is any further data I may be able to provide which may be of help to your analysis of this problem.
