Runtime RAID Reconstructor vs. ReclaiMe Free RAID Recovery

ReclaiMe Free RAID Recovery vs. Runtime RAID Reconstructor

Supported RAID levels

RAID levels denote the different ways of storing data in a RAID. Most of the RAID levels allow for the redundancy, with RAID 0 being a notable exception. For a RAID recovery software to work, you need to know which RAID level you have.

RAID 0YesYes
RAID 5YesYes
RAID 10YesNo
RAID 6YesNo

Special cases

Sometimes when a large array goes down, you just need more oomph. Or, you may be lucky to have one of the tricky RAID controllers which deviate somewhat from the academic RAID models.

Output capabilities

The RAID reconstruction process essentially gives you a set of RAID parameters. The parameters per se are not very useful. Obtaining correct parameters does not guarantee immediate RAID recovery. Typically, some intermediate step is required before the array data can be accessed, involving either a high capacity spare storage, or some interaction with a data recovery software.

Note 1: Requires a blank storage of the same size as the capacity of a failed RAID array.
Note 2: Requires an appropriate license for a data recovery software, none of which are free.

Beats the hell out of RAID Reconstructor

In the end of the day, ReclaiMe Free RAID Recovery is cheaper and more capable. Click the link to download ReclaiMe Free RAID Recovery.

Please note that the comparison above is valid as the things were in October 2011.

ReclaiMe vs. ReclaiMe Free RAID Recovery

Difference betweeen file recovery and RAID recovery

File recovery software aims to recover data from the broken filesystems and the result of data recovery is files and folders. The goal of RAID recovery is to find out the lost RAID configuration parameters.
We have developed both data recovery software (ReclaiMe File Recovery) and RAID recovery software (ReclaiMe Free RAID Recovery).
ReclaiMe File Recovery is a multipurpose data recovery software which
  • Works with a single drive or partition.
  • Recovers damaged filesystem.
  • Produces files and folder structure.
ReclaiMe Free RAID Recovery is a tool to reconstruct a failed RAID which
  • Works with multiple hard drives (RAID member disks).
  • Recovers RAID parameters.
  • Produces either a destriped array data as the image file, or the array parameter set.

Do I need the RAID recovery?

In some cases, it is obvious that there is a RAID failure. An extreme case would be a RAID controller card with visible burnt components, for which no replacement is available. Or, the RAID controller reports a double hard drive failure in a RAID5 and refuses to bring the array online.
There are other cases when the RAID recovery is not needed. First and foremost, the RAID recovery is not needed when there was no RAID. Surprisingly, the RAID recovery is not needed for a RAID1 (mirror). Mirror just holds two identical copies of data. Put either of the hard drives into the working machine and data should be readily accessible. In the worst case, you'd need ReclaiMe File Recovery, but no RAID recovery is ever needed for a RAID1.
There are however cases when the exact nature of the problem is not obvious. For example, a volume may refuse to mount due to either a filesystem problem or an underlying RAID problem. If the RAID-related origin of the problem cannot be positively determined, the best is to leave the RAID setup as it is and try the filesystem recovery first. The RAID recovery, which involves disconnecting the drives from the controller, should only be attempted if the filesystem recovery of the array "as is" is not successful.
