hi,

 

i'm running the latest beta with one parity drive. After the last parity check i had some read errors on one of my disk.

Since i could not figure out what the problem was i checked the SATA cables and after that i run again an parity check.

during this parity check i got more read error on other disk ending up that 3 of my 5 disk are now missing 

 

is all the data lost?

 

please help

Go to tools > diagnostics, attach zip.

 

Screenshot of main page can also help.

something really strange is going on.

i restarted the system twice and now i had "only" one disk showing as emulated.

 

I'm getting a bit worried.

 

any suggestions for the next steps?

Disk2 missing but SMART OK. Other disks look OK too. Does disk2 have a red X?

Yes it had. Right now I'm rebuilding it on the same HD, not sure if that's a good idea but I have right now no other HD around.

Should be OK to rebuild to that disk but you may have some issues with hardware other than your disks that caused the problem in the first place. Anything you can tell us about that?

It started with the last parity check where I had a couple of read errors from disk 1. Never had that bevor.  What I did is I changed the SATA port on the MB (asRock C2750).

Then I started a new parity check, during the same disk 2 and 4 had massive read errors about 32000. I tried to stop the array and the result was both disks got missing and even disk  1. I then connected disk 2 back to the original SATA port and restarted the system. All disks came back. Only disk 2 was in an emulated mode.
