RAID5 Background Initialization stuck at 0%?

ByLuca2k1 June 16, 2023March 29, 2025

Hello everyone,

I'll try my luck here, as I haven't found much information on the following topic so far

Two days ago, I received new servers (2x Fujitsu Primergy RX2530 M6). I created a RAID 5 on both systems about 32 hours ago, and both still show 0% during background initialization in the BIOS. Does anyone have any idea what could be causing this?

5 SSD drives of 480 GB each (1.8 TB RAID size)

I am happy to answer any questions you may have

Thank you in advance and have a nice weekend!

Bygeheim007b July 12, 2022March 30, 2025

I'm looking for a NAS, preferably a 1U enclosure, or, if necessary, as flat and wide as possible. It should fit four 2.5" drives plus a GBit connection. The main goal is to keep it affordable. Any tips?

Is the PC like new after formatting the hard drive?

ByLena1x January 3, 2025March 29, 2025

Hi I, or rather my father, formatted my PC, the hard drive, drive C. Now my question is whether the PC will then look like it was new when bought in the store, as if it had never existed before. My IP was blocked for whatever reason and I wanted to ask if it's gone…

SSD not recognized after PC crash?

ByKingPupa December 23, 2022March 29, 2025

Hey people, While I was on Discord earlier, my friends said my microphone wasn't working so well. So I unplugged the cable and plugged it back in. After that, everything froze. Then I shut down the PC by holding down the power button. Afterward, the PC no longer recognized my SSD with the operating system….

Hard drive ps4?

ByCoRo0348 August 13, 2023March 29, 2025

Hello, I bought an external hard drive for my PS4, but it has an external power supply. Does it have to stay on all the time to back up my games? Or can I turn it off with the PS4? Thanks in advance for your answers.

4. Hard drive is not recognized (B450 Tomahawk)?

ByAdvanPadawan August 27, 2022March 30, 2025

In this picture, you can see which one isn't recognized. I wanted to connect it to SATA 3/4, but the case won't allow it because the metal is swinging upwards right there. I updated the partitions and searched, but nothing. I think it's because SATA 5/6 has to be free. Could that be the case?

From somewhere I have in mind that RAID5 has a general problem with (at least usual) SSDs because of writing the many parity data, at least the TRIM is not clear. In addition, RAID5 means a lot of writing on the SSDs, which is generally life-saving. A RAID10 or something isn’t coming into question?

Is a dedicated raid controller, but I would find a defect in both servers funny.

Serial error in the controller or the SSD. Come on

I want to strangle one and see if it’s better with a new attempt

What I’ve learned: before I start the first firmware update if there is

The controller is from Fujitsu – PRAID CP500i and the SSDs are the MICRON 5300 Max, have attached an image from the iRMC to the question

Will at least be able to reset the RAID controller and test it again, maybe it’ll do something
