Recovering Data from a LaCie 2big RAID 1 Drive After Reformat: Possibilities and Best Practices
If you’re using a LaCie 2big RAID drive configured in RAID 1 and have experienced an unintended reformat, you might be wondering about the prospects of data recovery, especially if no new data has been written to the drive. This article explores whether recovery is feasible, the challenges involved, and the options available, including professional services.
Understanding the Scenario
In this case, the user initially had a LaCie 2big RAID setup configured as RAID 1, which provides redundancy by mirroring data across two drives. The drive was formatted with the HFS+ filesystem. Recently, an update to LaCie Toolkit software caused the drive to be reformatted as ExFAT, effectively erasing existing data.
Crucially, no new data has been written to the drive post-reformat, which is advantageous for recovery prospects. However, the drive’s current state appears to have affected its filesystem and structure, complicating data retrieval.
Challenges in Data Recovery Post-Reformat
Reformatting a drive generally erases the filesystem metadata, making the data less accessible. When a drive is reformatted as a different filesystem (HFS+ to ExFAT), the original directory structure and filenames are typically lost or become challenging to recover.
Using data recovery software may help retrieve the raw data blocks, but these tools often struggle to recover filenames and folder structures unless specific conditions are met or the original filesystem metadata remains intact.
Is Recovery with Original Filenames and Structure Possible?
- Likelihood of Success: Recovery of files with intact filenames and directory structures is dependent on several factors, including the type of reformat, whether the filesystem’s metadata was overwritten, and if the data areas were physically altered.
- Potential Methods:
- File Carving: Software can scan for file signatures within the raw data, but this usually results in recovered files being named generically (e.g., “File001”) without original folder contexts.
- Filesystem-Based Recovery: If the original filesystem metadata remains intact or partially recoverable, specialized tools may restore filenames and directory structures.
Given that the drive was reformatted, the chance of perfectly restoring the original organization is reduced but not impossible, especially if no new data has been written.
