Does uTorrent not hashcheck the file once it's done?

[Viper007Bond]

I've now had multiple torrents download bad where a piece or two is wrong. It shows as complete, but WinRAR says it's not. So, I stop it in uTorrent, force a recheck, and a couple pieces show as not downloaded right. I then have to start it back up and uTorrent will redownload these pieces.

How can I stop this from happening?

[DreadWingKnight]

It hashchecks pieces as they download.

Check your hardware (RAM, Hard drive) for damage.

I haven't done either recently, but memtest86+ reports no errors and I doubt my HD has any either, but I can check.

And only 2 of 54 torrents have had issues (3 pieces total outta a whole hella a lot), so it's not the end of the world.

In some users' cases, it's been bad IDE cables.

[Viper007Bond]

My hard drives are all SATA.

[Saribro]

A bad SATA-cable then .

[Viper007Bond]

Well I doubt it. I mean, 3 pieces outta 40 gigs downloaded since I installed uTorrent a couple weeks back? It'd happen more often I'd think if it was bad cable.

[Firon]

Not necessarily.

But then again, could be bad sectors.

It just happened again on a new 4.3GB torrent (a piece failed and only showed up after a forced recheck). :|

If it can happen to me, it can happen to someone else. Perhaps a forced check after the torrent is complete would be a good idea? I mean, ensuring that a torrent downloaded correctly is really, really important. Say perhaps a program modified the torrent's files while uTorrent was closed or something (I dunno, just trying to come up with an example where a torrent download could go bad)? I realize that pieces are checked once they are completed so that if bad data was sent, the piece can be snatched again, but I still think at least having the option to do a final check would be a good idea. I mean heck, would it be hard to add it as an advanced option? I wouldn't think so.

But anyway, I just queued a disk check for the next reboot (which I'll probably do in a few days). We'll see then if that's my culprit.

[Firon]

I think I put such an option on the todo.

Viper007Bond @:

Try look in "Preferences" then "Disk Cache" and try turn off "Advanced Cache Settings" in uTorrent.

I got the exact same problem and more often with the new version (1.6) then the previous (1.5)

Not that Firon isn't right about cables, ram and etc. but turning off the Advanced Cache Settings did help with almost every download

Firon @:

What exactly is the benefit with caching disks read and write ?

[Firon]

Not killing your HDD with a lot of very small writes thus overloading the thing?

[Viper007Bond]

I'm sorry, but I'll be leaving those on. I want to save my hard drive, not wear it out.

I think I put such an option on the todo.

Oooo, awesome.

[Viper007Bond]

Hmm, Check Disk reported no problems...

[Firon]

Tried SpinRite?

[Viper007Bond]

I highly doubt it's my drive (it's only a year or two old) and it's a good drive (Seagate 400GB SATA). Not to mention that I don't wanna spend a good 24 hours scanning my disk.

Oh well, I'll just deal with it until the planned feature comes along.

I encounter this issue a lot, and I have encountered it on three different HD's. It would be very nice to have a feature that allowed force recheck upon completion of a torrent.
