This means I try and be prepared and don’t trust hard disks as my sole backup. After seeing ReclaiMe me find data in mere seconds, maybe the easy option to give up is not always the correct action !īeing an IT guy, every time a client’s hard disk fails and they don’t have a backup, I share their pain and run home to make sure I back everything up. Glad we keep looking for a solution and found ReclaiMe.Īfter so much time wasted with Getback data and Rstudio it made sence to give up. Just goes to show you, there is no one specific tool to fix all problems. We are a big fan of the Getback data tools and Rstudio. I also noted a drive was powering down (Must have been a 3 disk RAID 5 with a spare) After 3 days, it got to 1.8% scanned and found nothing new. #Readynas 1500 usb flash recovery softwareApparently we have all the files we need but the software keeps scanning looking for scattered meta data, in case the product can’t find anything in the initial scan. I noted that the precent in the tool bar was still at 0.3% scanned. It was super quick.Īs soon as we had a file tree, we started to save files out. #Readynas 1500 usb flash recovery trialWe downloaded the trial for ReclaiMe and within seconds, it found the NTRFS container and started showing files. We tried Rstudio (Many online people said they had success). #Readynas 1500 usb flash recovery manualEven with manual settings, it found nothing. We tried NAS Data Recovery and even though it supports NETGEAR, it failed to locate a RAID. We could have selected stripe size, RAID sort order and more for days, and got nowhere. We tried RAID reconstructor and it failed to locate a RAID. However, in the end the recovery quality tends to be fairly good. The same copy-on-write feature also leads to another difficulty – the recovery time will be quite long, since the software has to analyze different versions of files and other metadata to choose the latest one. Because of this, file fragmentation is possible, slowing down file copying. BTRFS has many features like copy-on-write, checksumming, and creating snapshots designed to protect against data loss however, you can still lose data, most probably to a software bug.īTRFS uses copy-on-write feature, meaning that when you edit a file BTRFS does not delete previous data, but writes changes to the new place instead. Synology NAS vendor uses BTRFS filesystem in some devices as well. Starting with 2013 NETGEAR switched to BTRFS as the main filesystem in their NETGEAR ReadyNAS devices. Disks are still combined into a RAID using md, but the next level is BTRFS filesystem rather than LVM.īTRFS is a Linux filesystem which is sometimes used in ready-made NAS devices. In modern NETGEAR NASes data is stored in another way. The second group includes devices that use NAS OS 6, released in 2013 or later (Or units with upgraded firmware). As for filesystem, Linux ext4 is used in such configurations. In these “old” NETGEAR devices data storage is organized in the following way – disks are cut into partitions which are combined into a RAID with md (Linux RAID), and then md-arrays are combined into a single LVM volume. The first group includes the devices released before 2013 with operating system versions prior to NAS OS 6. NETGEAR devices can be divided into two groups. #Readynas 1500 usb flash recovery plusInside its ReadyNAS devices disks are combined into a RAID and used to store data, plus provide a variety of other storage-related services.Īll these functions are controlled by a Linux-based operating system inside the NAS, which NETGEAR calls “NAS OS”. ![]() NETGEAR is one of the well-known NAS vendors. We have to pull the drives and attach via Sata (Actually we used powered usb adaptors) and use data recovery software.įirst, we need to know a little about NETGEAR NAS units. They warned us not to try and put the drives into another unit as the unit will likely blank them ready for new use. NETGEAR quoted (Estimated) quite a large cost to recover the data. There are 4 disks in the NAS in XRAID format. We replaced the power supply and it is still not working. I have been presented with a failed NETGEAR NAS. ![]()
