Question Four Sata drives all stopped working at one time

[Alan Alan]

Ok, Let's start over. There are 4 hard drives on the Sata buss. They all show up in the bios but when Win11 boots up it there are no sata drives. Three of the drives are in raid 0 mode and the fourth drive is a solo SSD drive. Normally if one raid drive fails then the windows program Intel rapid storage technology shows the failed drive. That program also fails to run in windows. The solo SSD drive has also disappeared in windows drive manager. OK, that's what is wrong. This is an ASUS TUF Z370-PRO GAMING mobo. The power supply is 1000 watts and the voltage is correct. The operating system is not on the sata buss obviously, all periferals work. NOW, which one of you in this group has any clue as to what could possible cause this problem. Doesn't it seem odd that the bios identifies the sata drives yet windows has no clue there are any drives on the sata buss. I thought maybe the windows drivers aren't there so I reinstalled the chipset drivers. Still nothing works. Win11 is fully updated too.

and is causing the motherboard to shut down the sata power

No.

MoBo has 0 control over SATA power cables directly from PSU.

but I suspect the drives can be read by the bios even without power.

No.

No power = no drives are working.

How else you think the HDDs are making noise? Taking the needed power from 4th dimension?

so I kind of think the 4th drive (ssd) is shorted and the motherboard has shut down the sata power.

Again, MoBo can not control SATA power cables. Heck, MoBo can't control the PSU at all, other than saying to PSU to start working and telling how much power MoBo itself, via 24-pin ATX power cable, needs.

but windows doesn't find them.

Sounds like your RAID has failed and it brought down the whole array.

@Alan Alan

Update your post to include full system hardware specs and OS information.

Include PSU: make, model, wattage, age, condition (original to build, new, used, refurbished).

Disk drive(s): make, model, capacity, how full?

What RAID configuration? What was the reason for setting up RAID?

Do you have other backups?

Funny how an ssd can fail when it it's been a read only drive for years.

What do you mean with "read only"?

A drive in that state generally indicates it has one foot in the grave.

I guess the power supply powers the sata buss. That section of the power supply might have a problem. Seems to me the sata drives did have a one or two cable choice. Seems like the power was derived either directly from the power supply or thru the board. Yet I have power to the motherboard, I guess one of the drives blew a fuse or something and is loading the sata buss. I guess there's only one way to find out. Start disconnecting those drives. Only 3 of the sata drives are raided together but the system shows no sata drives period. I also ran intel's raid controller within windows and it immediately showed an error. So most likely the sata ports are not responding. Also the drives try to spin up then shut down as it boots. It seems they tried it twice then moved on. Obviously the mobo can control the hard drives by software, it just doesn't power them, on the other hand it might have the ability to turn the sata power off in case of a short or over current. That's what I meant about turning the power off to the sata buss. Do sata busses actually connect directly to the power supply or do they go thru an on off switch like a transistor on the mobo?

 

[Ralston18]

If you start guessing and disconnecting, etc, consider that you may lose even more data as a result.

Is all data backed up elsewhere?

System specs?

 

[USAFRet]

In addition to the full System specs, what type of RAID array was this?

 

[Aeacus]

I guess the power supply powers the sata buss.

You guess? So, you don't know for sure.
And, No. Drives are not powered via SATA bus. Only data flows through there.

Full system specs, including PSU make and model (or part number) is? Also, how old the PSU is, and was the PSU bought new or used/refurbished?

And as others have also already asked: what kind of RAID array was this? Did you use dedicated RAID controller (if so, make and model of that one)? If not, you connected the drives to MoBo and used software RAID controller?

I took a look at it. It's a standard sata bus with up to 6 devices. The power supply directly powers the sata drives. It's weird how the bios shows the connected drives but they're not working. Windows 11 doesn't know they exist. I disconnected all then tried one at a time and nothing changes. It's an asus z733 mobo. The bios says the power supply voltages are working. I took the bios defaults and still no change. All the USB and pcie drives are working. It's all backed up so no big deal data wise but it is strange. How can the bios recognize the drives, tells me what they are yet Win 11 has no idea they are there. Any idea?

Yeah, it's all backed up. The bios shows me all of the drives yet win11 doesn't know they are there. 3 out of 4 drives are configured as raid 0 the other is s straight SATA. Any Ideas?

 

[Ralston18]

My concern was that your data is backed up and protected.

Will defer to those who are more knowledgeable of and have more experience with multiple drives and RAID configurations of any sort.

 

[USAFRet]

RAID 0 (striped) requires that all members of the array, as well as the RAID controller, be present and fully working.

What is the raid controller here?
Motherboard, add on card, something else?

You're clearly trolling.
None of your texts make any sense - every sentence with "guess", "seems", "obviously", "likely" is utter nonsense.
You're using wrong terminology, wrong understanding of systems architecture and connectivity principles.
Probably you meant it to sound "smarter", but you're failing miserably.

It's an asus z733 mobo.

And also there's no such thing as "asus z733".
Google search finds absolutely nothing with such name.

How can the bios recognize the drives, tells me what they are yet Win 11 has no idea they are there. Any idea?

If raid 0 has failed, then raid volume is not available.
Drives involved in raid will still be detected.

 

[Aeacus]

The power supply directly powers the sata drives.

If so, MoBo has 0 control over power delivery to HDDs.

It's weird how the bios shows the connected drives but they're not working. Windows 11 doesn't know they exist.

BIOS operates on hardware level and on hardware level, it can detect drives connected to MoBo. That doesn't instantly mean that software wise, drives are working.

As i suspected, something happened with the RAID array, thus bringing entire array down, hence why Win doesn't detect the drives on software level anymore.

What Disk Management shows about the drives? It should show them, since BIOS detects them.

It's an asus z733 mobo.

There is no Z733 chipset. What there is, is only Z790 chipset. And if you have Asus MoBo with 6 SATA ports, it is most likely one of these 4,

3 out of 4 drives are configured as raid 0

Since RAID 0 provides no fault tolerance or redundancy, the failure of one drive will cause the entire array to fail, due to data being striped across all disks.

So, i don't even know why would you use RAID 0. Unless you did it where read/write speed is the intended goal. Or to create one large logical volume out of all drives.

As of what might have happened - drive failure would be most probable. Since when one drive fails, entire array will come down.

All-in-all, if you want better read/write speeds, get SSD instead. It will be far faster than HDDs in RAID 0.
Or if you want storage space, don't put HDDs into RAID. Use them as separate drives or bigger capacity HDDs if you want single volume.
Biggest HDDs currently are 24TB;
