Hard drive recovery is based on a single premise, duplicate the drive therefore you have data, Most drives fail due to some defects on the platter surfaces or some mechanical or electronic issue. These situations can be resolved by duplicating as much of the disk drive as possible to a target drive of equal or greater size then recovery can be performed using most data recovery software for Windows, Mac and Linux.

Costs, why so expensive?
The cost of getting something back that belongs to you may seem ridiculous and excessive especially when the original hard drive only cost a hundred or so dollars. I would normally agree, however having done many data recovery jobs in the past, I know that some jobs can take quite a while.
When I first started Computer Repair, I had a few Customers that needed data recovery. At that time, I had only brief knowledge of the recovery process, but I couldn't chance recovering the data my self... so I used to send it to a major data recovery company. They of course took your first born as payment.
After a while I went to visit these "Data Recovery Companies" and after talking to them found that their success was not all that great.
I knew I had to learn this highly lucrative field and started my own scientific analysis into the Art of Data Recovery. After about 10 years of research and many thousands of dollars, I am now quite qualified in recovering data from a failed hard drive, in fact my current success rate is 98% because I care about the Customer and really get pissed off with every hard drive that gives me a hard time, it's a great puzzle and I love it.
There are many types of hard drive failure, usually noticeable by a slowing of the Computer, this might be caused by a virus or a degradation or the platter surfaces on the hard drive. Hard drives are manufactured and assembled in a Clean Room, the process is not perfect and therefore the hard drive has an additional small filter to catch stray particulates that may have gotten through accidentally into the hard drive case before it gets sealed up.
Additionally the materials used in the manufacturing of the Platters and the heads are always under development and therefore not always perfect leading to hard drive recalls.

Seagate 1TB Firmware issues (hard drive bricking)
Recovery problems continued with the 1.5 Terabyte hard drive. There was a stuttering problem, at first it was assumed to be a bad implementation of the SATA protocol using the common chipset's, recovery was an issue. Seagate immediately worked to try to recreate the issue in an attempt to find where the recovery issue was. They were in no rush as 1.5 Terabyte hard drive is only about 5% of the entire market. When it was understood the the problem was more widespread, they decided to put out a couple of firmware revisions in an attempt to solve the hard drive issue and ease the recovery process.

In the 1.5 terabyte disk drives, there are 2 main revisions. the hard drive that has the "SD* firmware", and the line that has the "CC* firmware". They made revisions with the SD1A and CC1H firmware to fix these issues and started production.

However, Seagate, very reluctant to hand out their their firmware, these requests usually require contacting Seagate hard drive Support with your serial number so that they could verify the model number, part number, and firmware just to be sure they would provide the correct firmware revision. This used to work well until the drive bricking became an issue. If the hard drive is shut down after 320 entries are created in the journal or log space within the firmware, following the power up, the drive could fail on boot up to the extent that System BIOS would no longer recognize it, recovery was now an issue. This is a rare issue but still bad situation. Seagate would simply RMA the hard drives because it was so rare. They released the SD1A firmware to the public. The chance is very low that your hard drive just won't spin up. When they manage to develop the new good working firmware, the new flash should un-brick the drive. If that doesn't work, flashing it back to SD15 should get it to work again.

Testimonial
Our Lacie BigDisk ethernet 1TB hard drive failed following a power outage. This had happened before with no problem, however this time the hard drive would no longer mount. We sent it to Data Recovery, Inc in Montreal that immediately diagnosed the problem and recovered all the data over the weekend.

Thanks for all your help.

Poweredge 2850 raid data recovery

Dell Perc2 Failure

Dell Poweredge 2850 Server using an E4672507-03.01 64 Bit Dual channel RAID controller. The failed raid server is a RAID 5 configuration with 6 Maxtor Atlas 10K model 8J073J0 73Gb hard disks. Hard drive 0 and hard drive 5 had come offline and crashed the Dell server.

FACTS:

  • The Dell 2850 server RAID ARRAY was originally divided into 2 Windows partitions.
  • The first partition was getting very full, an attempt was made to free up some space ....CRASH AND BURN!! Windows decided to write part of a JPG to the partition table and beyond. The data was no longer accessible. RAID Data recovery became necessary. Hard drives were not working, individual hard drive recovery was needed
  • During the life of the Dell Server, a few of the failing Maxtor Atlas 10K model 8J073J0 73Gb hard disks were replaced.
  • Additional factors to the RAID failure must include the fact that the new replacement Maxtor Atlas 10K model 8J073J0 now have a capacity of 69.8GB instead of the original 70.1GB, ...bummer!!
  • The PERC2 RAID re-aligned each element of the array... but this did not CRASH the Dell RAID Server, it just made it more difficult for raid data recovery of the failed raid 5 array as explained in Data Recovery of a Failed Dell Perc Raid Server.

  • Power spikes caused bricking of both Seagate ST3500620AS Firmware: LC11 that LaCie used in the NAS.
  • The solution was to un-brick the drives and mount the Raid array with Ubuntu
