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)         


        

Answer 1

I suspect that you've found a race condition in NTFS that was previously not exposed since drives didn't exist that were fast enough to hit it. I don't think that TRIM has anything to do with it (though I reserve the right to be wrong!)

Either way, the proper way to handle this is to put the code in a Retry loop:

int retries = 3;
while(true) {
    try {
        doTheOperation();
        break;
    } catch (Exception ex) {
        retries--;
        if (retries == 0) {
            throw;
        }

        Thread.Sleep(100);
        continue;
    }        
}
