My system was configured with one Kingston SSD and a terrabyte Seagate hard drive. The hard drive started acting up so I removed it and ran solely on the SSD for a while. I decided to add a second SSD, a 240 GB Crucial M500. When I boot my system shows the two drives under "scanning drives" the Kingston shows as Raid Ready Functional. The Crucial shows as Single Disc 02 (no word functional). When the boot finishes I cannot find the Crucial anywhere. I assumed it would be under disk management where I would name and format it but I find it nowhere. System runs fine, just continues to think there is only one drive. There is an option to go into LD maintenance (which I assume is Logical Drive) when I reboot and the Kingston shows there as RaidReady. I have the option to add another LD and the Crucial shows up but I am afraid to do much in this area as I do not know the consequences and do not want to end up wiping out the Kingston with OS and programs on it. (I also do not consider either drive a logical drive so am confused by the nomenclature) Any advice on how I get this new SSD to show up? It will only be used for data, no need to transfer operating system or any thing elaborate. Thanks

Second SSD not showing up in Disk Management, Device Management or My Computer

It appears as though your SSD is set up for raid. I am guessing RAID 1 (mirroring). You don't mention what size the Kingston is. The system sees the new disk as a logical disk (LD) that can be added to the RAID array as a possible mirror so it would not show up as a available drive in windows. I think your MB handles RAID setup in the BIOS, but with no configuration info such as what brand or what model motherboard...
The solution will be to change the setting for the disks to non-RAID it might be a JBOD (Just a Bunch of Disks) option.
I am pretty sure the SSD and the HDD were showing up as separate drives before, right? You only have one drive letter showing now, right? and before you had two each different sizes?
You don't state what version of windows you are running.
Getting into the BIOS is your next step and reporting here what you find relating to the disks, before taking action would be the next step.

The computer is a Gateway computer with Acer Veriton M430 motherboard running AMD Athlon II x 4 635 Processor.
It was originally configured with a single hard drive.
I installed a 120 GB Kingston SSD and installed Windows 7, upgraded to 8.1 Pro and reformatted the original hard drive for data only. Both drives showed up (C and L). After a year the hard drive would suddenly dissapear until I rebooted. I reformatted it but problem continued so I removed the drive and decided to go with a second SSD, a Crucial 240 GB M500.
When I look in Bios I see both SSDs but when I look at Disk Management I see only the C drive. It is partitioned into Sytem Reserved 350 MB NTFS and C: 111.38 GB NTFS
Looking at "Integrated Peripherals" in Bios I see "On Board Sata Mode" is set to RAID
If I try either Native IDE or AHCI system will not reboot.
Thanks for any guidance

The hard part to understand is the sequence of events here as I am confused as to how the SATA mode got set to RAID instead of AHCI. The HDD was in the PC first and alone, so it was not configured with two drives.
You installed the SSD but did you swap out the HDD install the OS then add back the HDD which you reformatted?
If the SATA got reset to RAID during the swap then the HDD would not be seen as a separate drive.
But it does show up (in windows) as Drive L and the option to add it as a LD never comes up. So the SATA mode should have been AHCI.
So was there a BIOS reset to default at some point?
If you change the mode to AHCI does that update the Boot Disk Order screen? or does it remain set for RAID Disk?
Also when you tried the AHCI setting did you power down and restart or did you save and restart? A power down is indicated with a mode change.
Usually if a drive is configured for RAID the partition info is different so if you connect it to a controller set to normal AHCI it won't boot, but this is a software solution, so I don't think the drive setup would be different.
So I can't figure how we got here if that setting the boot order with the SATA AHCI setting doesn't work.
You could create an image file of the SSD on the second Crucial SSD by using a USB port and an external enclosure Win 7 mode backup hidden in win8 or cloning software.
The problem with some clone SW is it wants the origin drive to be in the external enclosure, the good part is size differential doesn't matter. But would a RAID drive be recognised in that enclosure?

Thank you for your feedback. I too am confused as to why this worked with a separate hard disk but not with a separate SSD. I stay away for BIOS so I know I made no changes but somehow the SATA AHCI changed to RAID. I have powered down completely and restarted but system will not start unless I reset the SATA to RAID. There is an option to delete the LD but it says all data will be erased so I am hesitant. I thought deleting the LD might allow me to change the SATA to AHCI and I do not mind reinstalling software but dealing with license keys (especially on Microsoft products) can be a pain so I will try to exahust all other options. Thank you again for your feedback.
The data would be erased if you are unraiding your disks. But that's how it's gonna have to be. Then you'll need to put whatever data you want again on the second SSD. If its been in raid with the first SSD, it'll also need reformatting and the OS re-installed. It looks to me you've accidentally pushed a wrong button in Bios.
