What is a hashfail on bittorrent?

Answer 1

Each torrent has a unique fingerprint called an info hash.

Among other information, the info hash has specific information about the content associated with the torrent.

As each "bit" of the content is downloaded, it is checked against the info hash to ensure it matches.

A "hashfail" is when content you have received through the torrent does not match the info hash's information on the content.

It is normal for a small amount of hashfails on a bittorrent transfer as the bits of the content being transferred sometimes get corrupted during the transfer.

These corrupted bits that fail the hash check are discarded and the bittorrent client looks for uncorrupted bits to replace them.

The hash check ensures that the final download will be uncorrupted.

Answer 2

A hashfail is a bit of data that BitTorrent or Utorrent doesn't want.

Basically, it's the urine from uTorrent.

There's nothing to worry about - however, too many hashfails and a disk image could not be mounted because of the error message: no mountable file systems.

Once I got 11 hashfails while trying to download football manager 2010 torrent. It threatened to take a week to complete -but great YouTube tutorials showed me how to speed it up.

Answer 3

uTorrent is a bittorrent client. Using a torrent or magnet link, uTorrent will download content from other users active on the torrent or magnet.

The content is distributed in small bits. When all the bits are received, you will have an exact copy of the original content.

Each torrent or magnet has specific content associated with it. This content is defined by an Info Hash. Every bit that is received by your client is checked against this Info Hash. If it does not match, then it is discarded. This is called a "hashfail".

it is normal to have some hashfails as content can be corrupted during transfer. This should only be a small percentage of the overall content.

The hashfail is part of the process that ensures your completed download will be an exact copy of the original.
