I don't have a job. I have many time. Let's me click Stop, Right click and Force Re-check. I love to click them many times. nothing to do in life. Greate feature! please don't add auto hash check. eventhought the options it waste your time to implyment.

why won't that be changed? seems to be an easy (optional) option.

my virus-scanner (Symantec AV Corporate 10.1.6.6000) saw, wrongfully, one of the downloaded rar parts as an Bloodhound.Exploit.158 virus. the download was at 70% at that time.

therefor my download wasn't valid anymore at the end, but utorrent didn't mention anything about it.

ofcourse i got an crc error while unpacking, but a auto re-check could have prevented this.

or not?

Nope auto re-check would NOT have prevented this.

Because µtorrent hash-checks every piece as soon as it has it complete. Doing a full hash-check afterwards is double work. If the torrent seems damaged afterwards that means a program edited the file(s) AFTER they were written to disk. If a packet is damaged between the sender and µtorrent it will report a 'piece failed hash-check' or something in the logger and re-download it.

If there is a program editing files while u are still downloading u should disable this program (while running µtorrent). The program in question could (and probably will) also edit the files after you have completed the torrent in µtorrent so hash-checking on Completion won't help. Hash-checking a download once it's finished 'might' indicate there is a problem but it won't solve it and if u are suspicious you can always force a hash-check. Making it default is a waste of time, CPU and other PC resources for the 99,999% of the people who do not suffer from these problems.

hi Lord Alderaan, that sounds like a pretty fair explanation!

but making it default isn't what i asked, just make it optional, so you have the choice.

turn this (advanced) option off by default, but if turned on do a recheck afterwards

It is precisely for those reasons that auto hash check exists. :(

Sending out corrupt pieces (even if corrupt by only 1 bit out of 4 MegaBYTES) costs downloaders extra bandwidth...and cost other seeders more upload bandwidth as well -- and even some download bandwidth.
