Hello all

This has started to happen recently.

Every time I download a large RAR (more than 700 MB), it won't extract properly, and will say there's been a CRC error of sorts. What does that mean?

This has been happening to every large file I download, from multiple sources! I really hope somebody can help me.

Thanks in advance.

You should run the .rar file (along with any associated .par, .par2 files) through a utility like QuickPar to check and recover errors:

Thanks for the reply, but this seems like a way to fix the already broken file. I was hoping to find a way to prevent them from getting broken, since this is something that is happening on my PC only. Other people have downloaded the same files, and they didn't get corrupted or gotten CRC errors.

Many times the source of the errors is due to the data transmission of the file. So you need to make sure that your internet connection is clear...

Call your provider to have them check for noise or signal degradation...

Isn't there a way to check it myself?

Last time I called them I spent 30 minutes trying to make them understand what I wanted (DNS problems). They insisted it was my browser (simply because it wasn't IE). They're untrained as hell.

You can check your speed at various sites (just Google "ISP speed test"), but (and I'm assuming you have broadband) without special equipment, there's little you can do beyond the basics (line filters, phone jacks, pings, etc.)
