[kid41212003]

I downloading this file [DB_L-E]_Tsubasa_Chronicle_Season_1_1-26, 4.36GB and when it's reach 97%, windows crash and reset, after reset utorrent checked the file and some of the file It's downloaded completed missing some peices of it, like the movies file at 100% it roll back 90 or even 60%, and It crashed 2 times and I lost like 12%.

Utorrent say It's downloaded 5.14Gb and the file only 4.36Gb and even the file not yet finish.

And I'm using Norton Internet Serurity and I need to update my virus definittions everytime the windows crash. Look like the virus file are gone too.

Sorry for my english, can someone plz help me?

EDIT: I'm defragment my disk, It's say no BAD SECTOR.

I'm alway play games so NO WAY, RAM BAD

Windows XP SP2

EDIT2: First Force Re-check, 83.4% ->92.1%

Sencond Re-check, 92.1% -> 96%

Third Re-Check, 96% -> 92.2%

Fourth Re-Check, 92.2% -> 94.6%

I downloaded alot file more than 4Gb, never have this problem b4.

EDIT3: While checking, the % checked goes up and down like download speed =__=.

stop force rechecking!

Everytime you start this, you loose all the unfinished pieces that are curretnly downloading.

See the pieces tab.

if there are, lets say, 20 pieces open a 4MB each and you force a recheck these 80 MB are lost.

And having downloaded more than the file is, is "normal" (hashfails, double recieved and discarded data and the force rechecks)

The file still downloading, even it's all finished, I watched them all =___=, something WRONG here.

Defragmenting doesn't tell you about bad sectors, chkdsk does, or HDTune. Playing games all the time doesn't necessarily guarantee that your RAM isn't defective -- run a scan on that too. Ew @ NIS. Uninstall it and get a better antivirus, like Kaspersky.

Check your RAM with memtest86+ for 12-24 hours. CHeck your drive with SpinRite too.

[kid41212003]

How to use SpinRite, I downloaded it, but dont know how to use. >.>

Either you create a bootable disc and run that, or install it on the drive (lol at least that's what I see from the screenshot).

[kid41212003]

It's won't boots, so I can't ran the programs, any others HDD check?

[Firon]

It should boot if you do it properly. Make sure you didn't just copy the file onto the disk, RUN it first and follow the instructions. If you choose the ISO method, burn it as an image with your CD burner app, not as a file.
