Bizarre directory delete behaviour on SSD drive

Question

Directory c:\\test has 50 or so files in it, no subdirectories.

    If IO.Directory.Exists(\"C:\\test\") Then
        IO.Directory.Delete(\"C:\\test\", True)

I've had problems with this before, but this is not specific to SSD drives. You would be far better off doing a move then delete:

if(Directory.Exists(dirpath))
{
    string temppath = dirpath + ".deleted";
    Directory.Move(dirpath, temppath);
    Directory.Delete(temppath, true);
}
Directory.Create(dirpath);

The other way to deal with it is to loop until complete:

if(Directory.Exists(dirpath))
{
    Directory.Delete(dirpath, true);
    int limit = 100;
    while(Directory.Exists(dirpath) && limit-- > 0)
        Thread.Sleep(0);
}
Directory.Create(dirpath);
