And see if you can then mount your flash drive. IIRC Mint does not install hfsprogs by default and you can't mount Apple's hfs filesystem without it.

Run hfsprogs: hfsprogs is already the newest version (332.25-11).

As long as you have backed up anything you wish to keep from your USB drive, it would be safe to delete both /dev/sdb1 and /dev/sdb2 and create a new partition on your USB drive, to replace them.

Sorry, Mas OS and window. How I can back up USB is i cannot see it ?

I meant you have copied any files off of your USB drive that you wish to keep. (or already have another copy of them, on a different drive/medium/disk)

Otherwise you will have to decide weather to try and mount your existing partition(s) or lose what ever is on them and delete them, and then re-format the partitions, on your USB drive.

I do not have copies nowhere. I am trying my best to mount.

I suspect your issue might be due to core storage.

As suggested it might be easier to use FAT32 instead of HFS+ if you need to transfer files back an forth between the two operating systems via "sneaker net" as long as the files are less then 4GB.

Assuming you have not corrupted the drive and it is still usable on the Mac can you copy the files back to the Mac?
Once you partitioned/reformatted the drive to FAT32 you can copy the files back and then they should be accessible on Mint.

mkdir /mnt/myusbdrive
mount /dev/sdb2 /mnt/myusbdrive

I totally agree with michaelk about "core storage" (as I suggested earlier on).

Let us know how it goes...

Mac OX sees the USB directory and 30 MB size but no files in. Winsdows do not see it at all. So, doesn't is mean that the drive got corrupted?

I Looked into this link

and have a question, How to find my own hard drive image name to follow the instruction ?

I think your referring to this:

Quote:

First get the partition's information from Parted, in bytes; you need the Start and the Size numbers. Here is an example of Parted session (as you can guess, my hard drive image is /mnt/macbook.dd):

Code:

$ /sbin/parted /mnt/macbook.dd
WARNING: You are not superuser.  Watch out for permissions.
GNU Parted 2.3
Using /mnt/macbook.dd
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) unit
Unit?  [compact]? b
(parted) p
Model:  (file)
Disk /mnt/macbook.dd: 160041885696B
Sector size (logical/physical): 512B/512B
Partition Table: gpt

If so, that is where someone has used the dd command to take an "image" of their hard drive. From my understanding, in your case, we are only talking about a USB drive, formatted with the HFS+ file system. Therefore the above would not apply to your situation, unless you have used the dd command to take an image of your hard drive's partition(s).

In relation to your USB drive, it sounds like it has been corrupted. Therefore unless you can recover said files from it, that you wish to keep, using data recovery software of some description, you may have to accept that said files, have been lost for good.

To my way of thinking, you can take one of two options:

1) Try and recover the files (if they can be recovered) using data recovery software.

2) Accept the loss and re-partition and then re-format your USB drive, with FAT32 file system (or a similar file system).

What do you want to do?

[QUOTE=jsbjsb001;5771706]Try typing the following in a terminal as the root user;

run it. Results: user@user-Latitude-E6440 ~ $ mkdir /mnt/myusbdrive

While that's because you are not running the commands as root; given your Mac is having trouble mounting your USB drive, there's probably no point in trying what I suggested there (sorry).

Have you made a decision re post #24 ?
