ExpressCache is no longer working after updating to Windows 10 Manual Fix

It’s now been several more months, apparently this is still a problem.

I have an HP machine with a 16GB sandisk ssd drive,  since upgrading from 8.1 to 10 (today) I’m unable to use the drive as a cache drive, I’ve uninstalled expresscache and reinstalled several times (the lenvo 64bit one, 1.3.118 and earlier versions.) wiped the cache drive, removed the MBR, etc  Then tried the one linked early in this forum (1.3.2)  the one on this forum reports:

“Could not find a Sandisk expresscache  device on your system please plug in your sandisk express cachedevice.”   

I’ve checked the drive in the bios hardware test, and in the registry it’s reports it accurately:   “SCSI\Disk&Ven_SanDisk&Prod_SDSA6GM-016G-100\4&2f202cce&0&010000”  so it does exist…     Even in disk management it’s shown as a healthy 14.91GB primary partition (not formatted / not available in explorer.)

So,  how can I convince expresscache that the SDSA6GM 16G drive is in fact what it is (sandisk ssd)

Thanks.
