Spanned 2 hard disks into 1 volume, one of the hard drive's wont work anymore after separation

[󠀡󠀡]

Hello, I've spanned 2 hard disks into 1 volume and decided to give 1 to a friend since i dont use that much space anymore, the thing is, i gave the hdd without formatting it or "undo" the spanning, he told me that the HDD is not seen in bios nor diskmgmt even tho i know for sure the HDD is in great shape and not broken. What could be the problem?

[tacoshy]

Is it recognized in BIOS? Does he use a NVMe SSD that doesn't allow him to use all SATA ports? The right SATA cable and power cable used?

I am not super familiar with RAID so that could also be the issue but I am unsure.


Your friend might have Windows installed in MBR/Legacy while the drive is partitioned in GPT/AHCI.

It's a BIOS setting thing.


Windows start button > Type "systeminfo"
In that list somewhere near the top look for "BIOS Mode". The PC Should be installed in UEFI, if it's installed in Legacy the machine will have to be converted.

How to convert: https://www.intel.com/content/www/us/en/support/articles/000024558/memory-and-storage/intel-optane-memory.html

After doing this the BIOS needs to be changed to UEFI/AHCI.

RAID doesn't expand your space. It only makes it so that the same data is partly written on each hard disk to make a whole. This makes the data on each disk smaller, and therefore faster to load.

This video sort of demonstrates what I just said.

So you have not understood RAID.

Only in RAID 1 data is splitted and stored on 2 disk in smaller file size as it is splitted. And it extend the space by the numbers of disk used 1:1. However RAID 0 is not but still faster and not because of the file size but because you can read from 2 disk simultiosly making it like dual channel HDD/SSD.

There are various forms of RAID. Some are to increase performance while others are for redundancy and some for a little bit of both.

In a RAID array the file size does not magically change; the data is either backuped (As in stored on multiple drives), divided over multiple drives (As in drive A takes the first half and drive B the 2nd half) or both.

Come on folks...you don't need to expand on the basics of RAID. The point is that it doesn't (as in does not) increase hard disk space.

Depends on how you see it. With RAID-1 you make 2x1TB drives effectively as a 2TB drive which is also faster thanks to higher bandwidth and reading capabilities.

It's however right that you can't make a RAID where 2x1TB drives become a 3TB drive.

The rest however you said was absolutely BS. By RAID the file size doesn't get smaller, it stays the same. It can't compress the file size. Also RAID isn't faster because of smaller file size for the same reason. In some cases RAID only adds redundancy without changing speed at all and in other cases the file size doesn't even get splitted.

So you might meet the right thing but the way you said it it was completly wrong.

No matter what you do with RAID, there is zero hard disk increase in available space. It's function is performance and data redundancy. If you have 2 1TB hard disks in a RAID array, you will still only have 1TB hard disk space. There is no need to expand on explaining it. If you had 4 1TB hard disks in a RAID array, you'd still have only 1TB hard disk space available.

The way I said it was correct.

When running RAID 0 the data will be split up in chunks and divided over the two drives. Meaning you can use the full 2tb of the 2x1tb array.

It doesn't matter because that's all the OP was trying to do...seriously, please read what I initially told the OP. You and I both know that your and tacoshy's explanations were totally unnecessary.

You're right it doesn't matter but not because the OP tries to do this. Read again carefully. OP broke up his RAID array and gave one of the drives to a friend who can't make the HDD work...

The question was never about how RAID works and your explanation is simply wrong. But you're right it doesn't help as it wasn't even close to the OP's problem as he never had issues with RAID in the first place.

You said "RAID doesn't expand space" and I assume you would mean that two 1tb drives can't become (according to the PC atleast) a single 2tb drive. That statement is wrong.

If that is not what you said you were going off-topic.

What was there to correct? Nothing. Doesn't = "Does Not". The video I posted demonstrates what I was talking about. There was absolutely nothing to correct. Y'all just jealous I was able to convey it in a way a person could understand.

It does. You can make multiple drives to one drive with a capacity equals the sum of all drives in that RAID.

Wrong again only in one RAID type data is partly written on multiple disk. In redundancy RAIDs the data is mirrored and a single drive from the rAID array (unless RAID-10) can work indepently as such

Also data files doesn't get smaller they stay the same. Also the file size doesn't make the RAID faster but the bandwidth...


So that was your entire comment where not a single part was even closely correct and none that is related to the OP's issue.

So you not made it easier to understand. You just posted Off-Topic stuff which also is incorrect in every way.

The OP's problem is simply that the disk was needing to be reformatted. and the RAID array dismantled...and everything reinstalled onto a single disk before handing the one over to his friend. Given how RAID works, it causes the issue just to hand over the hard disk without taking any steps to disable the array, and set up the hard disk left over as a single hard disk.

Since both hard disks were spanned as one hard disk, and that one doesn't work after being put into another computer, this would indicate RAID0 originally being used to span them.
