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.

Can remote access to NAS Lenovo Iomega StorCenter ix4-300d devices pose additional data loss risks?

Remote access to NAS devices can potentially pose additional data loss risks if proper security measures are not in place. Some potential risks include:

1. Unauthorized access: If remote access is not properly secured, hackers or unauthorized users may gain access to the device and its data. This can lead to data theft, modification, or deletion.
2. Weak or default passwords: If default or weak passwords are used for remote access, attackers can easily guess or crack them, compromising the security of the NAS device and its data.
3. Vulnerabilities and exploits: NAS devices, like any other technology, can have vulnerabilities that can be exploited by attackers. If remote access is enabled without regular security updates and patches, these vulnerabilities can be exploited, leading to data loss or compromise.
4. Network attacks: Remote access to a NAS device opens up another potential entry point for network attacks, such as Distributed Denial of Service (DDoS) attacks or Man-in-the-Middle (MitM) attacks. These attacks can disrupt the device's functionality or intercept data being transferred.

To mitigate these risks, it is important to follow best practices for securing remote access to NAS devices:

• Use strong, unique passwords for remote access accounts.
• Enable two-factor authentication (2FA) if supported.
• Regularly update the NAS device firmware and software to patch any vulnerabilities.
• Configure a secure Virtual Private Network (VPN) for remote access, which encrypts the connection between the remote device and the NAS.
• Disable remote access features that are not required.
• Regularly backup the data on the NAS device to an off-site location to mitigate the impact of potential data loss.

By implementing these security measures, the risks associated with remote access to NAS devices can be significantly reduced.

How to take hard disks out of the NAS and connect them to a PC?

Although NAS Iomega StorCenter ix4-300d 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:

1. 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.

2. 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.

3. Make sure to mark each hard disk in accordance with how they were installed inside the NAS.

4. 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.

   How to Order Remote Data Recovery

Restoring data with Hetman RAID Recovery

This program recovers data from damaged RAID arrays and is fully compatible with Lenovo Iomega StorCenter ix4-300d. 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.

How to recover data from a Lenovo

Iomega StorCenter ix4-300d has 4 HDD slots, and it supports the following array types:

• RAID 0;
• RAID 1;
• RAID 5;
• RAID 6;
• 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:

1. Make sure that you have enough free space to save the image. The image file size usually equals the disk size.

2. Select the disk in the main window, and choose from the menu Tools – Save Disk. You can select multiple disks to be saved.

3. 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.

   

4. 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 ix4-300d 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.
