As you have recovered data from the failed hard-disk, it would be best to buy a new hard-disk.
Yes, data can be recovered from a tape using various software available in the market.
Interpolation is filling in the data points between the data that has already been collected. Extrapolation is filling in data points beyond the data that has already been collected, or extending the data.
Since it's a full format, data can't be recovered unless it's only been marked for overwriting. If a program like wipe.exe is used (sets every bit to 0), the data can't be recovered.
Our experience of recovering the data from failed Raid Systems is unparalleled. We recover data from failed RAID 0, RAID 1, and RAID 5 systems regardless of configuration or manufacturer. We also recover data that has been rendered inaccessible as the result of a rebuild failure.
A database can be recovered from a failed transaction using a method called rollback, which reverts the database to its last consistent state before the transaction began. This is typically achieved through a transaction log that records all changes made during transactions. If a failure occurs, the database management system (DBMS) uses the log to undo any changes made by the incomplete transaction, ensuring data integrity. Additionally, in some systems, checkpointing can be used to minimize the amount of data that needs to be rolled back.
en.wikipedia.org/wiki/Data_recovery has a definition of what data recovery is all about. For the software you can go to getdata.com. They may even have more information as to what can be recovered and what can not be recovered.
Some data can be recovered if the computer is not backed up and crashes. Many programs or software can detect a crash and automatically backs up recent updates or data changes.
Data that has already been gathered from a larger population.
You can get support and get your data recovered at your local geek squad. They are pretty reliable.
overwriting data multiple times, rendering the data unusable ** "Shattering the hard drive platters with a a hammer" --> is the correct answer. The question is asking how do you "fully ensure data can't be recovered" - breaking it ensures this!
Capable of being recovered or regained.Regaining when the data is lost.
any formats, I mean really
