| Note: All the numbers in this survey should be given as a percentage of all
data recovery cases you received over the last year. |
Issues that need to be handled during hard drive recovery process.
Each field should state how often you have to handle a corresponding problem/issue (in percentages of all
drives you receive for recovery). Note: If the drive has more then one issue then each issue should be
considered independently, e.g. if a drive had failed heads, and after swapping the heads, it had read
instability followed by a corruption of the file system then all of these three issues should be counted
independently.
|
Drive failures (drive-level issues)
- Physical/Mechanical damage
|
| Head stack failure (failed heads/preamp): |
% |
| Disk platters scratch: |
% |
| Motor seizure: |
% |
| Heads stuck to disk platters: |
% |
| Other physical/mechanical issue: |
% |
| - PCB failure (electronic issue): |
% |
| - Firmware failure, e.g. translator corruption: |
% |
|
Disk read instability problems (disk-level issues)
|
- Unstable/degraded drive problems, e.g. occasional click or drive stops responding
at some point and needs to be repowered to continue imaging:
|
% |
| - Reading media problems (bad sectors): |
% |
|
Data corruption (data-level issues)
|
| - File System structure corruption: |
% |
| - User files corruption: |
% |
|
Note: This table may have more then 100% in total since drives often have more then one issue.
|
Initial cause of data loss.
|
| - Drive failure (drive doesn't give access to data at all): |
% |
- Drive read instability problems, e.g. drive gives access to data, but it stops responding
occasionally, has bad sectors, etc.: |
% |
| - Software issue, e.g. OS crash, virus attack: |
% |
| - User error, e.g. accidentally deleted files, reformatted partition: |
% |
| - Lost hard drive or user file password: |
% |
| - Other cause (please specify below): |
% |
|
| Total : |
% of 100% |
Cause of unrecoverable cases.
|
| - Unidentified/unknown nature of the problem: |
% |
- Lack of technology/tools, e.g. to access firmware, to swap a motor or multi-disk
assembly, to repair files: |
% |
| - Previous unprofessional recovery attempts: |
% |
| - Irretrievable physical/mechanical damage, e.g. disk platters scratch: |
% |
| - Irretrievable firmware damage, e.g. lost adaptives or PList: |
% |
| - Irretrievable file system damage, e.g. lost FAT or directory entries, corrupted file: |
% |
| - Inability to find physical/electronic donor parts: |
% |
| - Inability to find compatible firmware (to fix SA/ROM damage): |
% |
| - Reading media instabilities (too many bad sectors): |
% |
- Excessive time required to complete recovery process, e.g. long imaging, requirements
to fix an issue too many times during imaging: |
% |
| - Drive irretrievably failed during recovery process, e.g. due to degradation of parts: |
% |
| - Other cause (please specify below): |
% |
|
| Total : |
% of 100% |
Rating to improve commercially available Tools/Technology/Methods.
|
| - Deeper diagnostic tools (to see exactly waht is the problem/failure): |
% |
| - Physical/mechanical tools, e.g. heads or disk platters swap: |
% |
| - Better handling firmware issues (fixing SA/ROM): |
% |
| - Better handling media or disk instability problems (disk imaging): |
% |
