When a RAID drive is replaced and RAID rebuild errors occur, this may hinder you from accessing your files or even the entire RAID array. RAID may fail due to several reasons, a few of which include:Ī RAID controller may fail due to a disastrous power surge that can knock out the NVRAM, corrupt your hard drive partitions or damage the boot memory rendering it impossible to boot or access your data.
With this in mind, it’s imperative to continuously backup your data. Remember that RAID is not an alternative for backup and even the most secure RAID array configurations can still fail. The consequences are much more severe if important files were not previously backed up.
However, occasionally they are susceptible to failure just as other hardware devices and this may lead to catastrophic loss of data. RAID systems are generally considered a reliable and safe option for managing and accessing data.
