Updating boot support partitions for the volume as
I partitioned my hd into 3 pieces, one of which is somehow corrupt and that volume is most important. Actual hard drive Name : WD My Book 1110 Media Type : Disk Partition Map Scheme : Master Boot Record Disk Identifier :disk1 Media Name : WD My Book 1110 Media Media Type : Generic Connection Bus : USB USB Serial Number :574D415A4130313734313730 Device Tree : IODevice Tree:/PCI0/[email protected],7 Writable : Yes Ejectable : Yes Location : External Total Capacity :2 TB (1,999,696,297,984 Bytes) S. they are irreplaceable Verify and Repair volume “disk3s1” Checking Journaled HFS Plus volume. Unused node is not erased (node = 230) Checking catalog file.Disk utility acknowledges that it exists, but wont let me access it. thats great but how do i back it up when it will not mount. Invalid node structure The volume Terro Drive was found corrupt and needs to be repaired. Updating boot support partitions for the volume as required. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.The top-to-botom appearance of partitions shows the on-disk ordering.In addition to whole disk and partition device names, Apple RAID uses UUIDs to refer to existing RAID sets and their members.

But the System really includes another two areas for data on the drive.
With this feature, it's possible to resize the disk partitions online in RHEL 7.
Warning: Online partition table resizing is not a recommended process mostly because the underlying layer of an active logical volume or filesystem that relies on that information is being modified.
Remove a member or spare from an existing RAID set.
The journal for device will then be moved externally onto the newly created Apple_Journal partition.Erase a whole disk, writing random data to the media.) #: TYPE NAME SIZE IDENTIFIER 0: Apple_partition_scheme *1.5 MB disk2 1: Apple_partition_map 32.3 KB disk2s1 2: Apple_HFS Google Chrome 12.0.7...1.5 MB disk2s2 diskutil info /volumes/data Device Identifier: disk0s3 Device Node: disk0s3 Part of Whole: disk0 Device / Media Name: Untitled Volume Name: DATA Escaped with Unicode: DATA Mounted: Yes Mount Point: /Volumes/DATA Escaped with Unicode: /Volumes/DATA File System Personality: Journaled HFS Type (Bundle): hfs Name (User Visible): Mac OS Extended (Journaled) Journal: Journal size 8192 KB at offset 0xbd000 Owners: Enabled Partition Type: Apple_HFS OS Can Be Installed: Yes Media Type: Generic Protocol: SATA SMART Status: Verified Volume UUID: 87D2C53E-7563-3207-B019-528AC90F0B7E Total Size: 32.0 GB (32000000000 Bytes) (exactly 62500000 Blocks) Volume Free Space: 13.7 GB (13705142272 Bytes) (exactly 26767856 Blocks) Device Block Size: 512 Bytes Read-Only Media: No Read-Only Volume: No Ejectable: No Whole: No Internal: Yes Solid State: No sudo diskutil info disk0s9|grep UUID Volume UUID: D8FF2FE7-2E62-33BB-AAAE-88FE9C876849 Disk / Partition UUID: 9430124A-D283-474B-A076-9ABC354B5019 External firewire: sudo /usr/sbin/Diskutil info disk1 Whole: Yes Device / Media Name: WD Content (IOContent): Apple_partition_scheme Protocol: Fire Wire Total Size: 500.1 GB (500107862016 Bytes) (exactly 976773168 512-Byte-Units) Device Block Size: 512 Bytes /dev/disk1s3 468725256 421789664 46935592 90% 105447414 11733898 90% /Volumes/DGerman1a /dev/disk1s5 19399144 17794392 1604752 92% 4448596 401188 92% /Volumes/DGerman1b Whole: No Part of Whole: disk1 Device / Media Name: Apple_HFS_Untitled_1 Volume Name: DGerman1a Mounted: Yes Mount Point: /Volumes/DGerman1a File System Personality: Journaled HFS Type (Bundle): hfs Name (User Visible): Mac OS Extended (Journaled) Journal: Journal size 40960 KB at offset 0xe90000 Owners: Enabled Partition Type: Apple_HFS OS Can Be Installed: No Media Type: Generic Protocol: Fire Wire SMART Status: Not Supported Volume UUID: B2BA3CA8-984F-39F5-8A16-261BCBC2CE28 Total Size: 480.0 GB (479974662144 Bytes) (exactly 937450512 512-Byte-Units) Volume Free Space: 48.1 GB (48062046208 Bytes) (exactly 93871184 `512-Byte-Units) Device Block Size: 512 Bytes Allocation Block Size: 4096 Bytes Volume Name: DGerman1b Journal: Journal size 8192 KB at offset 0x97000 Owners: Disabled Volume UUID: 197341EC-7AA0-370A-8551-5644467E4753 Total Size: 19.9 GB (19864723456 Bytes) (exactly 38798288 512-Byte-Units) Volume Free Space: 1.6 GB (1643266048 Bytes) (exactly 3209504 512-Byte-Units) Continuously display system-wide disk manipulation activity as reported by the Disk Arbitration framework, Coming on-line, being ejected, volumes being mounted or unmounted, volumes being renamed, etc.
