SSD visible on 1 motherboard, partially on another, invisable on the third

[mattbar]

I have one machine with a very old motherboard. It has a pentium 4 processor. Single core 3.2ghz. This machine's hard drive has ubuntu on it. When I plug the SSD into it the SSD is always visible in the bios. I can access the drive. It says 58gb of 120gb are used, but the folder and files total to less than 1gb, and almost every single file is missing. For example there is no windows folder and program files only has 1 folder. I can view some pictures, there are some intact programs and zips 99% of everything just isn't there.

I think directories are corrupt and files could be recovered but I will gladly format it because the files are not important.

My machine has an msi x99s sli krait edition motherboard. When the ssd into my computer the bios sees the SSD, but disk management and samgsung magician do not. After restarting my computer the bios DOES NOT see the SSD anymore. After restarting the SSD is visible again. I switched from AHCI mode to IDE in my bios. I noticed that it was choosing the SSD as a boot drive (which it would have done the first boot but I did not notice) so I changed it to my HDD hoping that windows was ignoring the drive after it recognized it was unbootable and booting with my HDD.

The SSD was originally in my asus m4a77d. I have not recently tested it, but I'm pretty sure that the SSD never shows up in bios on this motherboard.

If it was on AHCI in the BIOS when you installed windows on the SSD, you should leave it on AHCI

So which computer do you use the most or do you want to fix? The old one or the new one?

And if the ssd is formatted in GPT, the old one wont be able to read it (well I dont think it can)

It doesnt have a UEFI BIOS and it wont support GPT partitions

AHCI was off when windows was installed on it. In fact I had to download AHCI drivers for windows before it could boot in AHCI mode.

It's the SSD I want to fix. Only the ubuntu machine can see it. I'm not 100% sure but I think I have to format it on a windows machine or else windows machines won't see it.

I formatted it using the administrative tool disk management to NTFS format.

My motherboard supports UEFI but I stay as far away from UEFI as I can. It has never been enabled.
