Moving Secondary Internal HDD from 14.04 to 18.04

I recently installed 18.04 onto a new machine and I wanted to move an old 4TB secondary internal HHD to it. I removed the drive from the old computer (after powering it down) and placed it in an external enclosure I had lying around. After plugging it into the new 18.04 box though the drive is not recognized.

sudo blkid 

returns

/dev/sdb: PTTYPE="PMBR" 

And when firing up gparted I’m confronted with this:

Invalid argument during seek for read on /dev/sdb 

also

sudo hdparm -N /dev/sdb 

returns

max sectors   = 7814037168/12631728(18446744072933654192?), HPA setting seems invalid (buggy kernel device driver?) 

I know the drive was formatted as ext4 on the old 14.04 box using gparted and was mounted using fstab in /Server. I’m not sure where to go from here. I figured it would be simple to move this non-system drive used for media from one computer to another. I have the data backed up but would prefer not to have to go through recovery unless absolutely necessary.

tablets getting disconnected automatically from hotspot in ubuntu 14.04

Used hostpad for creating hotspot. Below is the configuration for hostapd:

interface=wlan1
driver=nl80211
ssid=”Kolibri”
hw_mode=g
channel=1
macaddr_acl=0
auth_algs=1
ignore_broadcast_ssid=0

Please suggest a configuration so that hotspot can connect 60 tablets. Your help is appreciated.
