@prahal I have tried from ssh "smartctl -d sat -i /dev/sdc" and "smartctl -d sat -i /dev/sdd", the first has take 50 seconds, the second has take 1 minute. However with -d sat option it's more faster than the week ago but run "smartctl -d sat -i /dev/sda" it's take just 1 seconds. It's normal that time or not?

hi, thakk You for the answer, but my old monitor have a DVI connection and not VGA connection... so the adapter that I have is from HDMI side box and dvi side monitor. adapter is DVI-D type, so side hardware doesn't to be compatibility issue. As written by @MattWestB seems that it's due to video mode, but I don't know if there is and how add this patch Hi, I was thinking that @jock and @fabiobassa doesn't know for the existing of your nand driver. If You don't want that is made an armbian image with your driver no problem.

Dear to all, I have a Helios64 unit with 2 hdd (both WD60EFRX). I have bought also an external enclousure UGREEN 5 Bay Hard Drive Enclosure ( https://eu.ugreen.com/collections/hard-drive-enclosures/products/ugreen-5-bay-hard-drive-enclosure-5-x-18tb-raid-array-hard-disk-docking-station ) and 2 WD140EDGZ and these 2 hdd are mounted inside UGREEN enclousure because I want format and test it (when all will work fine I'll exchange a WD60EFRX with a WD140EDGZ so the drives inside the enclousure will have a backup scope). The enclousure is powered by external adapter, the system image installed is the Armbian 22.02.1 with Linux kernel 5.15.93-rockchip 64 and openmediavault 6.6.0-2 (Shaitan). If I have the enclousure turned off and from open media vault access to smart drive section (storage -> S.M.A.R.T. -> device section), the smart information (related to the 2 WD60EFRX) are showed in about 4-5 seconds but if I turn on the enclousure with the 2 device WD140EDGZ , the smart drive section is showed after 4 minutes. Sometimes the section isn't showed but it's showed an error message "Http failure response for http://192.168.1.44/rpc.php: 504 Gateway Time-out". I'm sure that this problem occur also with the transfer of files (hoping that doesn't occur wrong data information transfer with damaged files also) and I have already googled for this issue on the web but I haven't found nothing that help me to solve the issue. I attach here the 2 dmesg output that I have take from 2 distinct session with putty dmesg of first session dmesg of second session my question is: the problem it's related from standard drivers inside the image, from the kernel or it's necessary take manufacturer driver source and compile it? How can I solve this issue? Hope that somebody help me Best regards

@all ilmich has told me that he have made a port driver of NAND in his libreelec build. The driver is available here https://github.com/ilmich/LibreELEC.tv/tree/libreelec-10.0/projects/Rockchip/devices/RK322x/patches/linux/default . If somebody is interested, he can try to make an image armbian with kernel 5.10. I have forgot another issue with armbian legacy image: the board doesn't work on my old monitor 1280*1024. The monitor plug was of dvi type and I have used an adapter hdmi-dvi... Can be this the cause?
