My drives aren't all detected when I start the array after moving to a new machine (new but same board). 

 

I took out the drives into a hard drive toaster and all of them boot normal and are detected on my normal laptop.

 

I've provided diagnostics and an image of what the array looks like (apologies for quality). Would anyone be able to help me figure out what's going on? I have a backup of most of the data. 

 

Any input is greatly appreciated.

Check to see if they are being detected in the board BIOS.

Thanks for your help. I checked and only see 4 of the HDD drives. I have a total of 6. 

 

I got this from some old logs I had:

WDC_WD20PURZ-85GU6Y0_WD-WCC4M5UN4636 (sdh) 512 3907029168
WDC_WD100EMAZ-00WJTA0_1EGKSV7Z (sde) 512 19532873728
ST1000LM024_HN-M101MBB_S30CJ9DDC00672 (sdb) 512 1953525167
WDC_WD80EFAX-68KNBN0_VAHX169L (sdf) 512 15628053168
WDC_WD100EMAZ-00WJTA0_1EGAB99N (sdc) 512 19532873728

 

Here is a list of each drive's model numbers:

WD120EDAZ-11F3RAO

WD80EFZX-68UW8N0

WD100EMAZ-OOWJTAO

WD100EMAZ-00WJTAO

WD80EFAX-68KNBN0

ST8000VN004 [I was planning to use this IronWolf811d8eb460b23ddd79546314200bb51b55b28f3b.rtfd to replace either WD80EFAX-68KNBN0 or WD80EFZX-68UW8N0, can't remember which was having temp issues].

 

 

If the disks are not detected in the BIOS they also won't be detected by Unraid, swap both cables from a non working disk and see if it's detected.

I tried that and was able to narrow the problem to two of the drives. 

 

WD100EMAZ-OOWJTAO

WD120EDAZ-11F3RAO

 

When I put them back in the drive toaster, they're still detected on my laptop, but not in BIOS when I put them in the board, even after swapping the sata data cables around.

Could be 3.3v SATA issue:

 

 

OH RIGHT! I've heard of this issue but never experienced it. I'll review and report back.

It was in fact the 3.3v issue. I'm surprised it happened since I did not change anything other than re-buying the same motherboard. I followed the instructions in the video below to resolve it (using the tape). Everything now detects. Thank you!
