Hello, good morning. :)

I got some questions about the RAID 2, 3, and 4:
1. In RAID 2 and 3, if the parity disk is damage can I still recover the files?
2. In RAID 4, if the ECC disk is damage can I still recover the files?

Anyone?

The answer is yes! There is only one RAID configuration in which a single disk failure causes all data loss... striping without parity or mirroring (RAID 0).

It may be better to talk about the purpose for the RAID set. The only time I would employ RAID 0 is for something like a gaming computer where data loss is not a big deal, but performance is.

Thanks for replying my queries techsheaven.

I forgot to include this question. What does the Parity Bit do in RAID?

Error detection and correction. This is different from the parity block (the actual data).
