Ubuntu: /dev/sdb1 is apparently in use by the system; will not make a filesystem here
Solution 1
The mdadm --zero-superblock
looks like it failed because you weren't root.
However this may not be enough, isw_raid_member
is probably due to the disk previously being used as an Intel software RAID device. If it still fails, try:
dmraid -rE /dev/sdb
You may need to install the dmraid
package first.
Reboot after this and see if you now can use the disk.
Solution 2
sudo dd if=/dev/urandom of=/dev/sdb bs=1M status=progress
This command will delete the metadata and digital signatures which is even caused by Intel VROC (virtual raid on CPU), but takes more time depending on the size of hard disk.

I get this error when I try to format
dev/sdb1
:$ mkfs.ext4 -L data /dev/sdb1 mke2fs 1.42.13 (17-May-2015) /dev/sdb1 is apparently in use by the system; will not make a filesystem here!
where
/dev/sdb
has a partition that I have created withecho 'type=83' | sudo sfdisk /dev/sdb
:$ fsdisk -l Disk /dev/sdb: 1.8 TiB, 2000398934016 bytes, 3907029168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0x1507c58d Device Boot Start End Sectors Size Id Type /dev/sdb1 2048 3907029167 3907027120 1.8T 83 Linux
and

Conversely, if I try to mount this disk I get a
isw_raid_member
error:$ mount /dev/sdb /mnt/Data mount: unknown filesystem type 'isw_raid_member'
So I found
md127
:# cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md127 : inactive sdb[0](S) 1105 blocks super external:imsm unused devices: <none>
and then stopped it:
mdadm --manage --stop /dev/md127 mdadm: stopped /dev/md127 # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] unused devices: <none>
I then tried again to mount:
# mount /dev/sdb /mnt/Data mount: unknown filesystem type 'isw_raid_member'
if I try to wipe the superblock of the disk:
$ mdadm --zero-superblock /dev/sdb mdmon: /dev/sdb is not attached to Intel(R) RAID controller. mdmon: /dev/sdb is not attached to Intel(R) RAID controller.
When I try
testdisk
this is what I getDisk /dev/sdb - 2000 GB / 1863 GiB - ST2000DM001-1CH164 CHS 243201 255 63 - sector size=512 No ext2, JFS, Reiser, cramfs or XFS marker 1 P Linux 0 32 33 243201 80 63 3907027120 1 P Linux 0 32 33 243201 80 63 3907027120 No partition is bootable
Is it possible that this disk has been marked by another RAID like Intel Rapid Storage RAID or similar?

loretoparisi over 4 yearsyou were right! I did after
sudo -i
and update the reply here getting now:mdmon: /dev/sdb is not attached to Intel(R) RAID controller.
