Why can’t ordinary software tools restore files from RAID?
Conventional hard disks keep user’s data by writing it to their surface in a consecutive way, and this is how an entire file is stored on a single hard disk. However, when data is written to a RAID system, a file is divided into several parts. Then these parts are written consecutively to all hard disks within such array. The size of such parts may range from 2 KB to 2 MB, so each file is stored on several hard disks at the same time.
Such approach helps to speed up read and write operations, and it is evident that saving two parts of a file having the size of 1 GB to two hard disks simultaneously is much faster than saving the same 1 GB of data to one hard disk. However, this peculiarity makes file recovery more complicated.
Various RAID levels store information in different ways. Additionally, manufacturers like Lenovo also introduce some modifications to this process, and that is why data can be written to hard disk in a wide variety of ways.
Is there a risk of data loss if a NAS Lenovo Iomega StorCenter px12-450r device is physically damaged or stolen?
Yes, there is a risk of data loss if a NAS device like the Lenovo Iomega StorCenter px12-450r is physically damaged or stolen. If the device is damaged, the data stored on the drives may become inaccessible or corrupted. Similarly, if the device is stolen, there is a risk that sensitive data could be accessed by unauthorized individuals. It is important to have appropriate backup measures in place to mitigate the risk of data loss in such situations.
How to take hard disks out of the NAS and connect them to a PC?
Although NAS Iomega StorCenter px12-450r can be accessed over the network, you still need to take the hard disks out of the storage device and connect them to a Windows computer. Only in this case will the software be able to scan them properly. Here is what you should do:
-
Turn off the storage and disconnect it from the power supply.
WARNING! Before you start taking hard disks out of your NAS device, read the manual carefully. Incorrect actions may damage your network-attached storage and/or the hard disks within the RAID system.
-
Take the hard disks out of the NAS one by one, carefully removing them from their slots. Remember that the disks are extremely vulnerable: hitting or dropping them may result in serious physical damage.
-
Make sure to mark each hard disk in accordance with how they were installed inside the NAS.
-
Remove the hard disks and connect them to the computer. In this video, we have explored what ports are used to connect hard disks, and what to do if there are not enough ports or connectors.

Restoring data with Hetman RAID Recovery
This program recovers data from damaged RAID arrays and is fully compatible with Lenovo Iomega StorCenter px12-450r. The hard disks that make up the RAID contain technical information about the algorithm used to save files. When launched, Hetman RAID Recovery reads this information and puts the damaged array together. Then you can open the disk and save your files. Also, you can recover the files accidentally deleted from the network drive.
Iomega StorCenter px12-450r has 12 HDD slots, and it supports the following array types:
- RAID 0;
- RAID 1;
- RAID 5;
- RAID 6;
- RAID 50;
- RAID 60;
- JBOD;
NAS supports:
- exFAT, VFAT, FAT 12 / 16 / 32;
- NTFS / ReFS;
- APFS / HFS+;
- Ext2 / 3 / 4 / ReiserFS / XFS / UFS / ZFS / Btrfs;
- VMFS / HikvisionFS;
Safe recovery from disk images
This utility lets you save an entire copy of the disk to file and then work with this image instead of the actual disk. Such feature helps to protect data on the disk from:
- Overwriting during the recovery process;
- Loss resulting from bad sectors;
- User mistakes.
To create an image, do the following:
-
Make sure that you have enough free space to save the image. The image file size usually equals the disk size.
-
Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.
-
When the image creation wizard starts, you can choose to save the entire disk or select only a part of it. Specify the parameters and click Next.
-
At this stage, you need to choose a directory where to save the image. Choose any disk connected to this PC, or save the image by FTP.
Where are user’s files stored?
The Lenovo Iomega StorCenter px12-450r network-attached storage keeps LifeLine operating system files on a separate RAID 1 (mirrored) array. Usually, all NAS systems create several volumes on every hard disk, and the first of them takes up to 2 Gb of space. This is where operating system files are stored. Other volumes are united into a RAID array where user’s data is written.

Yes, it is possible to recover data from a NAS Lenovo Iomega StorCenter px12-450r device that has been affected by a controller failure or disk array problem. However, the process of data recovery can be complex and may require the assistance of professional data recovery services.
In case of a controller failure, it may be necessary to replace the faulty controller with a new one and ensure it is compatible with the NAS device. This can be a delicate process, as it involves handling sensitive hardware components.
If the issue is related to a disk array problem, it is essential to identify the specific problem, such as a failed disk or a corrupted RAID configuration. In some cases, replacing the faulty disk and rebuilding the RAID array may be sufficient to recover the data. However, it is crucial to ensure that the correct procedures are followed to avoid further data loss.
It is recommended to consult with a professional data recovery service that specializes in NAS devices to assess the situation and provide the best course of action for data recovery. They have the expertise and tools required to handle complex data recovery scenarios and maximize the chances of successful data retrieval.
