When the data is worth 400
Data Recovery Principle
 If you dont know why the data is not
accessible if you dont have the experience or
technology to accurately diagnose and repair the
problem dont try to recover the data.

Data Recovery Process

• Do Your Due Diligence Ask The Right
  Questions
• (What happened to the drive, did it fall, was it
  bumped or banged, making any noises, what has
  been done to it so far, is it spinning, does it
  get power)
• Identify the Symptoms (Tell me what happened)
• Determine the Cause
• Develop/Implement a Plan
• Recover the Data

I Dont Want My Drive Repaired
I Just Want My Data Back
1. Hard Drive Repair
The process of bringing a failed or failing drive
to a fully functional condition temporarily in
order to image the drive. (Firmware or Hardware
Failures)
2. Data Recovery
This is where the files are actually recovered
from the drive to a stable and safe environment
to be delivered back to the client. (Advanced
Recovery Utilities)

Common Disaster Areas

• Recovery Software
• Dropped Drives
• Bad Sectors
• Opening a Hard Drive
• Head Swaps
• Platter Swaps
• Clicking Drives
• Overwritten Data
• Monolithic Flash Drives
• RAID 0 5 Issues
• NAS Devices (Drobo,LaCie, Synology)

12
Recovery Software
1. Deleted Data
The safest time to use recovery software is when
you know the data has been deleted. Most users
install it on the same drive they are recovering
from. HFS is the least forgiving in recovering
data that has been deleted.
2. Failing Drives Do Not Run Check Disk
If you dont know why the drive is failing, or if
it has bad sectors, using software to recover the
data is like playing Russian roulette.
Depending on why it is failing, it will cause the
drive to fail quicker and potentially damage the
drive to the point it is not repairable or
recoverable.
13
Dropped Drives
The First Thing Everyone Does Is The Worst Thing
When a drive experiences any shock, there is at
least a 50 chance the read/write head assembly
has come out of alignment or even worse, come out
of its parking place. If the drive is spinning
and this happens, the chance of damage rises
drastically.
14
Dropped Drives

1. What is the first thing everyone does?
2. Internal damage?

15
Bad Sectors

1. Causes file system and file corruption
2. Software will get stuck in most cases
3. Drive must be imaged using special hardware to
   avoid killing the drive
4. Do not run check disk
5. Cannot be repaired

16
Opening a Hard Drive

1. Do you know what your looking for?
2. Do you know how to fix it when you find it?
3. Are you in a safe environment?
4. Alignment Issues
5. Last resort for professionals
6. Dont do it!

17
Head Swaps

1. Needs to be done in a certified clean room.
2. Finding a donor requires almost finding an exact
   match.
3. Donor vendors know what the drives are being used
   for.
4. Platter damage will ruin the donor heads.

18
Platter Swaps

• Cant you just take the platters out and suck the
  data off?
• Cant you just take the platters out and put them
  in another drive?

The only time a recovery warrants a platter swap
is when the motor/spindle is seized. Very few
companies in the US can do this procedure.
19
Clicking Drives
Usually a drive will click because the heads
cannot read the service area on the platter and
does not know where to go next. Some times this
is due to corruption to the modules located in
service area.

1. Clicking drives do not automatically need a clean
   room, or head swap.
2. Many firmware related issues cause clicking
3. Platter damage will cause a drive to click
4. Bad Heads also will cause a drive to click

20
Overwritten Data

• Plain and simple. GAME OVER.

21
Monolithic Flash Drives

1. No printed circuit board
2. All components inside the memory chip itself
3. Requires knowing the pinout
4. Very difficult to reverse engineer

22
RAID 0 5 Issues

1. Power down immediately
2. Do not force back online
3. Do not reinitialize
4. 1 2 drives down
5. Need to know why the failure occurred
6. Basically dont do anything you would not bet
   your life on

23
NAS Devices (Drobo, LaCie, Synology, Etc)

• Tech support is NOT your friend
• Do not run disk utility or check disk
• Do not reinitialize
• Do NOT use the default/proprietary array
  configurations BeyondRAID (Drobo), SHR (Synology
  Hybrid RAID)
• Always set RAID to custom RAID 5 or 6
• Need the box for recovery 90 of the time

Drobo Support
On May 19 at 1013 AM the disk in the 3rd slot
from the top with serial number XXXXXXXXXXXXXXXX
was power cycled because it had become
unresponsive and when it was redetected it was
assigned a new logical disk number.At that point
the array is down one drive so the Drobo started
data protection.While trying to complete, the
disk with serial number YYYYYYYYYYYYYYYYYYYYY
started misbehaving causing the Drobo to reboot
because now this disk was critical to the
operation of the array.If you can get a good
clone of the disk we should be able to get the
array stabilized.Kind Regards,XXXX
