I had to do a system reset on my pc-  after reset my usb bitlocked device was not visible in explorer I re initialised it an it is now there but it is no longer encrypted and the files are gone.   I am on uefi and turned off secure and fast boot to reset I don't know if this affected the drive, but my files are gone anyway.  I have the bitlocker code on another usb device but if I look in TPM no active TPM can be found.  In disk management there is a used section on this drive so there are files in there that seam to be locked out,  so question is have I permanently locked out this partition on  this drive or can I recover it somehow.              anybody help with this

Mike, your details show that you are not really sure what happened.
You need to add some details, though:
-Before your system reset, was your OS bitlocked as well? If so, were your USB devices setup for auto-unlocking of bitlocker?
-What do you mean by  " I re initialised it"
-What do you mean by  "it is no longer encrypted" - does it have a file system on it at all? Or does does management say "raw"?
-Where's your backup? (sorry, but you need to ask yourself).

no os was not locked --auto unlock not on--had trouble with an asmedia host controller when I updated the driver the usb devises were disable had to go to MB usb to get back to bios disable secure boot and get to windows troubleshooter via repair disc  but it was not good till i managed to get back to my microsoft account and updated drivers  the device did not show up at all in file explorer when i rebooted.   in disc management it was unallocated and it now says healthy primary partition.   file back up is on recovery drive also and I have scoured it for files everything is there of course but the one you want, but I did not think encrypted files save to back up drives anyway they not there.  the usb now looks like a normal drive can save and use it normally.  the recovery drive also says in file explorer 6 free of 28 and I know this is not correct as i recently cleaned out old files.  I use a usb3 hoo too hub and I do not think it is compatible with w10 I think the only stable driver is the microsoft 096 and would advice anybody to leave this alone. I will get rid of it after this event but I think these files are gone as the usb thumb drive was in during the fault disabling and re enabling usb ports while in place--  unless you can think of something

No, too hard to diagnose without even looking at it. If the partitions got mangled, it is pretty hard to recover the data.

"in disc management it was unallocated and it now says healthy primary partition."
What occurred to change it from "unallocated" to "healthy primary"?  And what specifically is "it" in this sentence?  Is it a drive (which one?), a  partition, a USB stick, or ?  What are you looking for on this device or partition?

once again I feel a bit guilty about asking this question and wasting peoples time but I always like to try and learn new things if I can and bitlocker has given me some problems over the years.  Anyway I gave it some thought this afternoon and I was right I did not trust it this time! and kept an old copy usb stick with about 80% of the files still on it and that's a result.   I am sure these files are gone due to the unusual cause.  so just lucky me      thanks for your time guys sorry for being a waster
