Finder can't see my external hard drive

Disk Utility can see external hard drive, but finder not.

Also i cannot mount the external hard drive.

I tried to repair, i can see how many files are there, it was working normally before.

Also when on other computer with windows it's working. In windows I can access all the files normally.

When I bought it first I format this in my mac with fat and then i was using normally long time since now.

This is from disk utility:

Verify and Repair volume “PASEK”Repairing file system.** /dev/rdisk2s1

** Phase 1 - Preparing FAT

** Phase 2 - Checking Directories

** Phase 3 - Checking for Orphan Clusters

64331 files, 247388960 KiB free (7730905 clusters)

File system check exit code is 0.Updating boot support partitions for the volume as required.

MacBook Pro with Retina display, OS X Yosemite (10.10.2)

So I got this in terminal

MacBook-Pro-Micha:~ michalpasek$ diskutil list

/dev/disk0

#: TYPE NAME SIZE IDENTIFIER

0: GUID_partition_scheme *121.3 GB disk0

1: EFI EFI 209.7 MB disk0s1

2: Apple_CoreStorage 120.5 GB disk0s2

3: Apple_Boot Recovery HD 650.0 MB disk0s3

/dev/disk1

#: TYPE NAME SIZE IDENTIFIER

0: Apple_HFS Macintosh HD *120.1 GB disk1

Logical Volume on disk0s2

B942247B-CD79-4662-AC55-A8F5CB811939

Unlocked Encrypted

/dev/disk2

#: TYPE NAME SIZE IDENTIFIER

0: FDisk_partition_scheme *1.0 TB disk2

1: DOS_FAT_32 PASEK 1.0 TB disk2s1

MacBook-Pro-Micha:~ michalpasek$ diskutil mount /dev/disk2s1

Volume on disk2s1 failed to mount

If the volume is damaged, try the "readOnly" option

MacBook-Pro-Micha:~ michalpasek$ diskutil mount force /dev/disk2s1

Usage: diskutil mount [readOnly] [-mountPoint Path] DiskIdentifier|DeviceNode

Mount will mount the volume in the "standard" place (/Volumes), unless

an optional mount point is specified.

I tried a few comand in terminal which I found in internet like sudo, fsck_hfs and few other, but it still not working.

Like I said before the disk is not broken as it start normally on windows.

I am going abroad in few weeks and I only take my macbook with me and i have a lot of documents in this hard drive, that's why I try to repair it.

Hi

Since I installed Yosemite (and all updates), my external portable LaCie 1TB has rarely been visible. This is both in the Finder and with DU. Last night I plugged the drive into an iMac 27 (running 10.10.3 and with no wifi problems either) and it came up with no problem. Ran Disk Repair in DU and all was well. Just to try something different (and simple), I renamed the drive on the iMac desktop - simply went from LaCie 2 to LaCie 3. I plugged the drive back into my MBP and so far, 24 hours later, all is well with the drive visible in the Finder and running Time Machine back-ups. I'll come back if it disappears in the near future.

BTW I tried all the above - mount/unmount in Terminal - with no joy.

Cheers

TY

I tried to repair the disk from DiskUtility in the first place.

I don't have other Macbook's near me as I cannot try with other system.

I will try maybe just go to some shop with macbook and ask if I can put my hard drive just for a moment in their laptop as maybe this will be solution.
