I'm trying to wipe an IOSafe external drive, and I'm running into a major problem. When I run
dd to wipe the full disk (
/dev/sdb) it errors out at the 1.8 GB mark (it's a 2 TB disk), saying no space left on device.
sudo dd if=/dev/zero of=/dev/sdb bs=4M status=progress
When I go to wipe
/dev/sdb1 (the partition, that oddly enough shouldn't even exist, because I wiped the partition table), it will wipe that.ea
Any idea what's going on and what to do about it?
fdisk -l /dev/sdb:
Disk /dev/sdb: 1.7 GiB, 1770082304 bytes, 3457192 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x1f7d3f72
As requested, the output of ls -l /dev/sdb*
$ ls -l /dev/sdb* -rw-r--r-- 1 root root 1770082304 Oct 27 07:17 /dev/sdb brw-rw---- 1 root disk 8, 17 Oct 27 07:18 /dev/sdb1
Now that I see that output, does the 'b' in the sdb1 line denote a block device?
