So my pc one day take long 10 minutes time to boot up. And when it did i saw that in the this pc section its volume name showing but no storage indications. When i click on it it is showing cant access this drive as it does not exist. I opened the disk management it was showing the hard drive as RAW. I Cant change it to NTFS or acces it as its showing foesnot exist(same for cmd). It is also not showing up in the BIOS system information.
