Ext. USB SSD: can't change partition type from "ntfs" to "ext4"
by kaza from LinuxQuestions.org on (#58FW8)
Hello!
I'm trying to connect an external SSD (USB) to one of our LINUX servers
to be visible (and accessible).
It came with a "ntfs" partition. At first I thought it's no problem
to "mount" it as "ntfs" type is among the known types. But I've got
an error:
mount: unknown filesystem type 'ntfs'
So I decided to remove the "ntfs" partision and to create a LINUX partition
instead.
Here's how the disk is visible:
Code:lsusb
Bus 002 Device 005: ID 1058:1078 Western Digital Technologies, Inc. Elements Portable (WDBUZG)
lsscsi
[10:0:0:0] disk WD Elements 1078 1065 /dev/sdcI've run "fdisk /dev/sdc", deleted the partition, created new GPT
partition table, added a partition, here's how "fdisk" sees it:
Code:
fdisk /dev/sdc
WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

sdc1 ntfs Elements F474B7AA74B76DCCI attempted to disconnect the SSD and re-connect it (thought that maybe some
cached information remains somewhere) but nothing changed: "fdisk" sees the

What am I doing wrong?
TIA,
