description:
ever since bought above bay , 4tb hdd (previously 1.5tb in own enclosure) have run error 30mins after drives connected.

can see it's being used seedbox deluge running, being used nfs share.

have tried different usb ports, power adapters , tried different raspberry pi problem persisted.

never had problem before new bay. bay works fine in pc. both drives formatted ext4.

things connected device usb cable bay, power cable , ethernet cable.

have spent several hours trying other suggestions of fixes (things changing max sector size) i'm still inclined believe must sort of power or incompatibility issue.

halp.

thanks

i'm looking way roaming = 0 in lan, can't figure how it... i'm looking in hostpd.conf , here 802.11r / iapp etc... has managed roaming = 0 system? got lan multiple wired pi ap running in bridge mode eth0 , wlan0. separated ssid, , time change 1 other long. please advice me, thanks. br i have not tried setting pi access point wireless admin , note seem saying each pi has separate ssid. mean device needs learn every pi's ssids , not roam new pi until connection previous 1 gets bad, @ point device re authenticate next pi, causing drop , reconnect, not roam. wireless roaming want use extended service set (ess) , have each pi using exact same ssid, client doesn't need reauth or , can associate same ssid different pi. of course want make sure each pi set different wireless channel don't interfere each other. sorry can't offer more point in right direction. raspberrypi
