Why Samsung Magician software doesn't recognize my 840 EVO RAID? How can I update the firmware?

post #1 of 5
Thread Starter 
Hi, I have a notebook with two Samsung 840 EVO 1TB in RAID, at BIOS it shows SATA MODE: RAID and when I open the Samsung Magician software it doesn't recognize both of them, it's named Intel array, something like that, how can I use the software and update the firmware since it doesn't recognize? And what is the difference between AHCI and RAID mode btw?


Thanks! thumb.gif

Your description is somewhat confusing, you say you're using RAID mode and have two 1TB 840 EVO's in "RAID" (RAID 0, RAID 1, etc?) but then you are confused about RAID mode?

Is the size of your two EVO's in a RAID array equal to ~2TB? I'll assume you have a RAID 0 array/volume, not that it matters for your questions.

RAID combines two or more drives into one "logical" drive, or one drive as seen by the OS and the user.

RAID arrays are created by software and/or hardware, and one or both of those things is a "layer" or intermediary between the OS's file system and the actual drives used to create a RAID volume. So an OS, file system, or any other software does not communicate directly with the drives in a RAID volume, but with the software and/or hardware that makes a RAID array/volume possible. That causes the normal communication between software and a single disk drive to no longer exist, unless that software knows how to deal with the RAID software, and the RAID software cooperates.

Even given that ability, not all of the normal communication between software and a disk drive is possible with drives in a RAID array . Single drives used in RAID mode do not have that layer between them and software, so they interact with it normally.

The Magician software does not recognize SATA RAID mode. That is at least partially due to several different standards/designs of creating RAID arrays used by different manufactures. For example, Intel and AMD use different standards for their RAID implementation.

Since it cannot communicate with each SSD in a RAID array, it can't perform any of its usual functions. So you cannot update the firmware when those SSDs are part of a RAID array. That is normal for any SSD in a RAID array, no firmware updates can be done... at least in an OS (Windows) or software running in an OS, like Magician.

If you read the help documentation provided with the Magician software, you'll find a method that allows you to update the firmware outside of Windows. That involves creating a bootable optical disk or USB drive that contains the firmware update program. You also must change the SATA mode from RAID to AHCI before booting into the firmware update device you created. Once done updating the firmware, you exit the bootable device, go into your BIOS, change to RAID mode, and then boot into Windows again with your RAID array intact. That is, as long as the firmware update is non-destructive of the drive contents, which will be stated in the firmware update info.

AHCI mode is an advancement over IDE mode that includes features and options IDE does not provide. You cannot create RAID arrays in AHCI mode.

Sorry that is because my english isn't good, but I have RAID 0 array volume Intel, can I change to AHCI and boot Windows and go to Magician to update the firmware of each SSD separately? Because I tried to change to AHCI but it said I would need probably to reinstall Windows

If Windows is on your RAID 0 array, you cannot change to AHCI mode and boot Windows, that will not work.

A RAID 0 array puts any files on both drives, split into two or more parts (two drives = two parts, three drives = three parts, etc.) When a file is read from a RAID 0 array, all drives read the part of the file they have, and the RAID software puts the parts together into one normal file.

In AHCI mode, the RAID software is not being used, so you cannot read any files from the drives. That is why you cannot boot Windows from a RAID 0 array in AHCI mode, all the Windows files cannot be read and put together to be used to boot the PC. If you had Windows on another drive, and use AHCI mode, Windows cannot see any files on the drives that were put there in RAID mode.

But as I said before, you can change to AHCI mode and use a bootable USB flash drive with the firmware update software on the USB flash drive. Then you can update the firmware on each SSD, I have done that myself, it works fine.

The Magician Help section of Magician has instructions to create the bootable USB flash drive for a firmware update.

Yeah as parsec said you cant run a raid array in AHCI mode; that's for drives that are not in raid(great explanation parsec). I have the same problem as you, I have two 830 Samsung 128gb ssd in raid 0. Samsung software sees my raid drive but does not recognize the drive as a Samsung ssd. Which in turn limits what I can do in the program with the drives (back-up drive, make image discs, ect.). I believe its because its in raid mode, and the software has trouble differentiating between the drives. Since I am using the on-board Intel raid controller the Samsung program sees it as a Intel drive and not Samsung which it does not support. Now it might work if you use pci raid controller card; but that a slim chance; Like I said I think it because its in raid. In terms of the Samsung Magician software there is really nothing special about it, so I never really worried about it.
