How can I verify my download?

With 10+ 200MB files with *.01-10 for example
How can I check to see which one is corrupt if it says ‘Broken’ in 7-zip?
Rapidshare does not show md5’s for any links unless an uploader exports details… :/
EDIT: It says broken during extraction of the 10+ part file
Answer #1
Get winrar, split the download and then test the archive. Once it’s uploaded, it’s the downloaders problem.
Answer #2
You can’t really, if there is not a SFV file. You can just try to extract with WINRAR, and see at what point it tells you there is an error. Extract one by one the files, make a new folder and put 01 there first and start extracting, then add 02 when needed and so on, and st some point it will tell you there is an error and you should know which file it was.
Answer #3
WinRAR helps you identify the faulty files. Anyway, you can always check the size of the first 9 files. They should be the same in size. The faulty ones will have a lesser size than others. Download those again in order to able to extract files. If you still cannot extract then redownload the last one (.10) and try again.
