Either that, or stop poking at it until you have something to copy it onto.

I agree, that I was not thinking clearly at this time.

I do have some good news to report, though. I have the drive mounted, and I am in the process of copying the data off.

---------- Post updated at 01:31 PM ---------- Previous update was at 01:08 PM ----------

I tried to manually copy the folders from one drive to another.

I tried to copy files from the failing drive to another drive. I get this error, "The operation can't be completed because the item XYZ is in use."

So then I try to open the terminal and issue this command:

Code:

$ cp -R /Volumes/Data/Software /Volumes/DATA2/

And it starts, then errors out.

So then I tried to tar up the directory. That started, then would error out.

I was going to try the dd command like suggested, but the destination disk was smaller than the amount that I had on the source disk. I am not familiar with that command, and I couldn't see how to copy a specific directory over.

So then after I was about to cry (not really...well almost), I realized that rsync would probably work.

So I kicked this off, and I got one directory to sync over to my other drive. I will do the other one now. I didn't want to tempt it, and just did the most important data first.

Code:

rsync -larP --exclude ".DS_Store" --exclude ".TemporaryItems" --exclude ".Trashes" /Volumes/Data/Software /Volumes/Data2/Software >> /Users/<snipped>/Desktop/rsync.log 2>&1

lvscan

LVSCAN(8)						      System Manager's Manual							 LVSCAN(8)

NAME
       lvscan - scan (all disks) for Logical Volumes

SYNOPSIS
       lvscan [-a|--all] [-b|--blockdevice] [-d|--debug] [-h|--help] [--ignorelockingfailure] [-P|--partial] [-v|--verbose]

DESCRIPTION
       lvscan  scans all known volume groups or all supported LVM block devices in the system for defined Logical Volumes.  The output consists of
       one line for each Logical Volume indicating whether or not it is active, a snapshot or origin, the size of the device  and  its	allocation
       policy.	Use lvs(8) or lvdisplay(8) to obtain more-comprehensive information about the Logical Volumes.

OPTIONS
       See lvm for common options.

       --all  Include information in the output about internal Logical Volumes that are components of normally-accessible Logical Volumes, such as
	      mirrors, but which are not independently accessible (e.g. not mountable).  For example, after creating a mirror using 'lvcreate  -m1
	      --mirrorlog disk', this option will reveal three internal Logical Volumes, with suffixes mimage_0, mimage_1, and mlog.

       -b, --blockdevice
	      This option is now ignored.  Instead, use lvs(8) or lvdisplay(8) to obtain the device number.
