SSD not seen by CrystalDiskInfo

I have a Dell Inspiron 7577 with a Toshiba KXG50ZNV256G NVMe SSD.  The SSD appears to  be working fine, but for some reason CrystalDiskInfo and SSD Life do not see this disk.  I have a WD hard drive installed also and CrystalDiskInfo sees this disk only. Anyone have any idea why neither program sees my SSD?

Re: SSD not seen by CrystalDiskInfo

Same her on one month old XPS 8930. Sent an email to Crystaldiskinfo support 3 weeks ago, but no response yet.

The Toshiba KXG50ZNV256G NVMe SSD is OEM suplied only, so not available to purchase by the large public and therefore less supported than more popular SSD drives.

I found a free workaround ( even with gadget ) at https://www.hwinfo.com/
See collected info below

Re: SSD not seen by CrystalDiskInfo

Is your SATA mode in the BIOS set to RAID rather than AHCI? Despite the name, that setting affects NVMe SSDs too. If so, having the SSD places behind the Intel RST controller is probably the culprit. Unfortunately that setting isn’t supposed to be changed without reinstalling Windows. There may be a way to do it in-place, but I haven’t looked into it.

Re: SSD not seen by CrystalDiskInfo

Hi,

Juyst received an xps 13 i purchased off outlet.  getting 1200mb/s seq read and 450 seq/write!  Checked bios and noticed SATA is set to RAID for some reason.  It should be AHCI right?

Slow write performance on Toshiba NVMe SSDs in the Inspiron 7577 (and other systems, including non-Dell systems) has been discussed quite a bit both on this forum and elsewhere on the Internet.  There's no good answer other than replacing it with a Samsung unit, unfortunately.  Dell doesn't seem to accept this as grounds for a warranty claim, and even if they did, there would be no guarantee that the replacement wouldn't be another Toshiba SSD.  Obviously not an ideal situation especially when some other Inspiron 7577s ship with Samsung SSDs that perform as expected, so it's a bit "luck of the draw", but that's where things stand at the moment.

As for RAID vs. AHCI, it doesn't make a difference in your case.  All Dell systems ship in RAID mode mostly for historical reasons.  RAID mode is required to allow Windows 7 to run on an NVMe SSD (although new systems won't run Windows 7 properly for other reasons), and it's also used for systems that have a spinning hard drive and a small SSD cache module so that the latter can accelerate the performance of the former.  If neither of those things applies to you, then you can switch to AHCI, but your performance won't change meaningfully in either direction, and making that change while you have an OS installed as opposed to doing it before performing a clean install involves some extra steps anyway, so it's not really worth it.

Re: SSD not seen by CrystalDiskInfo

Same problem here with XPS 8930 purchased Jan 2018 with Toshiba SSD not seen in CrystalDiskInfo. Emailed developer months ago but never replied. I guess because this is an OEM model used mostly by Dell.

As pointed out HWInfo can see the device and extract relevant information like Total Host Reads and Writes and Drive Remaining Life in %.

Re: SSD not seen by CrystalDiskInfo

I had a similar problem and I think I might have solved this.

I put an XPG SX8200 nvme SSD in my Inspiron and re-installed Windows 10 from the Dell image. It appears that the Dell image assigned some wacky drivers that I couldn't undo no matter how much cajoling I did -- it thought that the SATA controller and the SSD were AMD RAID devices, even though the laptop has an intel chipset! Like this, Windows appeared to run okay, but both the manufacturer's SSD toolbox (Adata) and CrystalDiskInfo acted like they couldn't see the drive at all.

However, installing Windows 10 from an image received through Microsoft's media creation tool appears to have identified everything correctly, installed the correct drivers, and now all tools can see the drive as intended. So I can only assume there's some oddity in the Dell image.

Hope this helps someone.

Re: SSD not seen by CrystalDiskInfo

It seems I am having same problem of not able to see the SSD in CrystalDiskInfo and SSD tool (I am using Crucial P1 NVMe) after I reimage the system as per the usage of new SSD. 

So, does it work to display back the information if I change back to AHCI instead of RAID ? And does that change require the re-install of windows 10 from dell image? That's a painstaking task as that's quite a long while to take. ..

Re: SSD not seen by CrystalDiskInfo

Just installed the latest Crystaldiskinfo 8.0.0 on my one year old XPS 8930.Still no Toshiba SSD detected.

I am happily using Hwinfo + gadget for Toshiba SSD read%, write% and Remaining Life %

Would not tamper with disk controller settings with the risk of having to reinstall Windows while the issue is not guaranteed to be resolved
