[solved] Download management tool - failed crc checks => broken hardware?

Hi,

M/B: MSI - Z97 GAMING 7 (MS-7916)
CPU: Intel® Core™ i5-4690K CPU @ 3.50GHz
HVM: Enabled
IOMMU: Enabled
Cache: 256 kB, 1024 kB, 6144 kB
Memory: 16 GB (max. installable capacity 32 GB)
OS: Unraid 6.5.3
HDDs: (5+1)*Iron Wolf 4 TB (Storage)
SSD: 950 PRO 512GB NVMe (Cache Drive)
 

 

I'm currently debugging my system. So I use the Jdownloader Docker to Download Stuff. A while ago I noticed that 40-50% of files I download fail at crc checks. Most (>99%) of them are split into multiple parts - like 5-10 .rar archives.

 

To Debug I did the follwoing:

  • Disabling the CRC Check to try to force a unzip => resulting in a corrupt file while extracting.
  • tuned on "download again" if-CRC-check-fails-option to workaround this issue => resulting in infinite loops
  • delete and setup docker again w/ deleting all concerning files in appdata to determine if it is something i messed up in configs => no difference
  • switched to a different docker (there are only 2 on the Com. Apps Store) because maybe some weired update hickup => no difference
  • asked a friend: does this happen to you with <same-files>? to determine if files are corrupt => Answer no
  • started the Windows App, download <same-files> to determine if it is my ISP => no issue
  • Checked SMART of SSD => seems fine
  • Extended Check of HDDs => still running

 

So what I think out of the questions are currently

  • ISP
  • broken Docker(s)
  • broken original files on the hoster

 

So right now I'm figuring out how to debug my Hardware. All Downloads go to Cache Drive (nvme SSD/ 950 PRO 512GB) first and will be moved at 11 pm to HDD. So naturally, I removed the Cache Drive from the Download Share. Also no change. So right now I'm figuring out if it is a coincidence that HDDs (6x Iron Wolfs (4TB) that all fail. The SMART report of my SSD seems to be fine. The extended Test is still running on all HDDs.

 

Is there something else I can check? I want to narrow down the issue and possibly solve it.

If not using ECC RAM run memtest.

I have had jD failing to extract perfectly good archives all the time. Have you tried extracting manually in a Windows envi with the latest version of WinRAR?

Yes, tried this also but I got an error like "corrupted file" or cannot find foo-bar.

ordered new ddr3 ram. Unfortunately, the CPU doesn't support ECC RAM, so I have to play the lottery again. when I do an upgrade next year I will also take a focus on ECC RAM.
