How to recover mdadm RAID 0, 1, 5 array in Linux?

Using RAID arrays allows you to increase data security. But we should not forget that RAID arrays can also fail. Often the cause is the peculiarities of the operating system. The most important point is that RAID failure often cannot be repaired with the built-in Linux tools. In this article, we will discuss the main causes of RAID failure in Linux and what to do if a RAID array fails.

Creating the software mdadm RAID in Linux

Recovering Hybrid HDD’s: Easier Than You Might Think

With the advent of ultra-fast SSD drives, nearly everyone was toying with the idea of replacing their big, loud and power-hungry hard drive with a slim and silent SSD. The extremely high speed of SSD drives is, however, countered by their high cost per gigabyte of storage, which in term limits the practically affordable maximum capacity of such disks to between half a gig and one gigabyte (as of mid-2015).

Fixing Hard Drives: Don’t Try It At Home!

While software-based recovery is pretty much the only method available to ordinary computer users, this method has an awful lot of assumptions. It needs your hard drive to be working and in a reasonably healthy condition, both mechanically and electronically. Your computer’s BIOS must recognize the hard drive, at very least exposing it to low-level functions of the OS. Finally, the OS must be able to read the drive, at least in low-level mode.

Linux File Systems: What You Need to Know

Linux. Lots and lots of people are using one or more Linux devices without realizing it. Android phones are running a variation of Linux, with their internal storage formatted in one of the Linux-supported file systems. Ubuntu is also a version of Linux. Many Web servers and nearly all NAS (Network Attached Storage) devices run an embedded version of Linux. Your home Wi-Fi router is probably Linux. Even your digital camera is most probably running embedded Linux! Chances are, your refrigerator and coffee maker will run Linux, sooner or later.
