Hard Drive not recognized

Post by Polar Bear » Sun Jul 20, 2014 3:59 pm

Yes.... I'm a total newb to Linux. After years of saying "I'm fed up with YOU KNOW WHO, i finally installed Linux on my PC. What a treat, or so I thought. I downloaded, Burned a DVD and installed Linux Mint 17 Mate 64-bit. Yeaaa... it's different, but the basic use of the Linux window is similar. the question I have is this morning when i logged in, my second hard drive was not showing up on my computer. When I re-booted I was asked for the password and was notified that it mounted. But nothing appears on "Computer", "File system" or "Devices". Any insight would be appreciated.

Look in /media/yourname/

Also try opening a terminal and entering

Code: Select all

findmnt
or simply

Code: Select all

mount
Good luck :wink:

Thanks WharfRat. I ran findmnt and mount... I don't understand output. I don't see anything that pertains to either of my drives.
Nothing shown in media/yourname/.

Unless you explicitly mount the disk's partition it will not show with mount or findmnt. However if you opened it in the file manager then it will show.

Can you paste back the output of

Code: Select all

sudo blkid
and

Code: Select all

mount
to have a look at what you're working with :?:

Why do you think you have two hard drives? Was it because you saw two of them when using windows? How large was each "drive"? Maybe instead you had one drive that was divided into two partitions to which hard drive letters were assigned?

I have two physical hard drives; a Samsung SSD 840 EVO 500GB is used for OS and programs. The second hard drive is a Western Digital 1TB used for files only.

Polar Bear,

I think I have to tell you some bad news. You don't have a second hard drive and I don't think you ever did. If in windows the disk manager showed a D: then it was a partition on your single hard drive. It's a mistake other users have made.

For a quick explanation, linux looks at block devices much differently, Your first hard drive will be a device called /dev/sda as you can see with the output of blkid and mount. The first partition, which windows depicts as C:, will be /dev/sda1 in linux. Subsequent partitions on the drive would be /dev/sda2, /dev/sda3 etc. Linux's sda2 would be the D: in windows. The second physical hard drive would be /dev/sdb.

Also you chose the encrypted installation which utilizes the logical volume manager and uses the entire disk. If you did have another disk it would not have been touched and you would see /deb/sdb partitions sb1 etc.

I hope you didn't have anything important on that partition or, if you did, you have a backup of it :(

Well then, what I just answered is totally incorrect if you do have two physical drives.

Was the second drive partitioned and formatted :?: Is so what filesystem :?:

It was originally formatted but not partitioned with Windows Vista 64-bit. It is only used for data storage. I used Truecrypt for security and password protection.

I did not install Truecrypt on Mint. When I installed Mint 17 i disconnected the WD 1TB HHD. I connected it about a week after installing Mint and the crypt program for mint asked for a passphrase... so I entered a passphrase and the drive functioned properly for 2-3 weeks.

well the drive is not recognized as onboard, it would not be an external drive or a caddie drive?

Partitions come before formats. What do you format other than a partition? Did you use the windows or linux truecrypt version?
