I have installed a 2nd SATA 500Gb hard drive in my existing Fedora 19 computer.  How do I get the OS of recognize and use this new HD?
Thank You all for any help

[Keith]

Hi Emp53 - and welcome to the Forum.

Once the new HDD is attached, it should appear listed in your file manager. 
I am not familiar with Fedora but if it works anything like Ubuntu, you can also check with the following command:

Code Select Expand

df | grep "/dev/sd"This should list drives sda1 and sdb1

By the way; is the new HDD external or internal?

It is internal installed on the SATA3 connector on the motherboard.  Seagate New in box.

[emp1953]

The results of that ls | grep command only show sda1.  nothing else.

[emp1953]

Under activities there is a "disks" utility that is a gui representation of whats in the system.  This utility shows two 500Gb seagate hard drives,  the first one listed as the master boot record and is the one that I assume I boot from and contains my Fedora OS.  its device Id is /dev/sda1 and shows a mounting location
The second device Id is /dev/sdb  this does not show a mounting location.   If it is /dev/sdb then do I simply need to mount the device, if so, where should I mount it?

By the way the HD box does not say whether it is formatted.

[Keith]

1. First of all, please copy and paste the output from the df command that you entered so that we can see what's happening.

2.

I presume you mean the box it came in.  But it will be formatted.

This looks good.
Now please execute my suggestion:

Code Select Expand

df | grep "/dev/sd" and post the output here. It's best to copy the output and paste it here, rather than just typing it. 

[emp1953]

[email protected] ~]# df | grep "/dev/sd"
/dev/sda1                               487652    103222    354734  23% /boot

[Keith]

That's interesting:  fdisk recognises the new disk but df doesn't. 
I don't have any ideas at present, but will have a think.  Perhaps another Member can help.

[emp1953]

Does it need to be mounted?

[Keith]

It does indeed.
First of all, try

Code Select Expand

mount | grep "/dev/sd"to check if it's mounted somewhere unexpected.

[SeZo]

It looks to me that dev/sdb is not partitioned:

Disk /dev/sdb: 500.1 GB, 500107862016 bytes, 976773168 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

Missing the partition data

[Keith]

The fdisk -l command doesn't list partitions, I think.  It didn't list your sda partitions.
Please execute

Code Select Expand

mount | grep "/dev/sd"and report the full result.
