Hash check results in less than 100%. Hard drive going bad?

Set file properties to read only, then rehash and download the missing parts, windows is changing the properties every now and then especially with the ratings and all on windows media player.

ahhhhhhh that, actually, check MWP if its configured to update your file, if does, disable it, might fix your problem, well most of them.

I had a similar problem a long time ago, and then it was a problem with the main memory.
I suggest that you run http://www.memtest86.com/ or something similar to check.

Ahhh, the mysteries of hashing. I still remember my 4 hash-failed files. I keep a hash record of everything, CRC32 for video in filenames and SHA1 for music in a FVA. I have a "main" drive and a "backup" one with the exact same files.

Not so long ago I decided to hash everything from my "backup" HDD. Out of 7500 files (~1.2 TB), 4 MKVs failed hash. The HDD seemed fine (no SMART probs or anything), and everything else in the PC was fine. I checked the files on the "main" HDD only to see it was the same 4 bad ones. No wonder, I was dumb enough when I switched my old, "main" 1.5TB with the new 2TB HDD, to copy everything from the "storage" drive and not from the disk being replaced. So both drives would have the content from a "same source". Should the backup had been corrupted and the main remained safe, the "good" files would have been saved. But in what I did if the "backup" was bad, the "main" would carry the bad files.

Lol, long story short. Whenever the files got bad, or I copied the wrong CRC32 in the files from start, I have no idea. I still have the 4 bad files that seem to be ok. I have to watch them to see how they play (I muxed them myself, and 3 of them are not available anymore to DL again).

That was my only case of bad hashes. I continued on the same system, same OS, drives, everything and never had a fail again. If I do a hash now I'll get the same results. Anyone else had bad hashes out of the blue?

Mwa, don't think your HDD is dieing. If it did, you probably would have gotten a device I/O-error.

If you really think your HDD is about to die, use a diagnostic tool on your HDD. They actually work (although I have no idea how they work).
I guess somewhat new BIOS version already include such tools, or you can download one from the following links:
I haven't checked all these links, just copy-paste from HP support forum which I came across when my HDD died. The Seagate link works, but you can only use it on Seagate disks of course XD
