You mean the hard drive has no problem? I can use it as normal, after I replace the old PSU ?

I had bought a new PSU, It's on the way.

My power supply has two output cables that support SATA, I connected three hard drives in parallel to each A total of 6 hard drives I don't have GPU device. I'm not sure you can find this PSU in your country , The following picture is the property of the PSU:

I also suspected the problem of the power supply, but the theoretical power of my power supply is 400w, which should be enough for six hard drives. This problem caused me to lose dozens of G of important data lenas-diagnostics-20230605-0316.zip

As a non-native English speaker, looking at SMART reports makes me dizzy, and I would really appreciate any help in analyzing the cause of the problem. One extra problem, when my hard drive is doing parity check, the speed of one of the hard drives suddenly decreases with a 'dada' sound. After a period of time, this hard disk will be disabled. Even if this hard drive is a new hard drive just bought

Disk 4 is suddenly disabled, I'm not sure why, the following text files are SMART reports, in two hours. TOSHIBA_HDWD120_Y62RKWPIS-20230605-0128 disk3 (sdb).txtTOSHIBA_HDWD130_40FU176AS-20230605-0236.txt

Now I‘m using UFS to recover files as much as I can. I can't revert parity disk as latest parity result? what is the logic of update parity result ?

Really 😭😭😭😭😭

Today I found that one of my hard drives lost the operating system, then I formatted the hard drive, and restarted unraid during the formatting process. When I restarted, this hard disk returned to normal, but the content stored on your side changed from hundreds G to 30G. Can I roll back my parity disk to restore this part of the lost content? I once had correct parity results
