Partition other than C are hidden

[MoonSaghar]

Hello, I need help regarding hard drive partition mising issue. My laptop is running win 10 and have 4 partitions of 500 HDD. Suddenly D E F drive partitions gone hidden, only C drive left. How do I recover the 3 hidden partitions. Disk management is showing them as full space allocated to partitions. No used space showing. When I click on them, it asks for format the drive. How I recover the partitions. Please help....

I'm not giving commercials. I have used MiniTool Partition Wizard 9 to recover a partition. However, before doing so:
-- make a backup onto any reliable external media your present C partition
(I highly recommend making a full image of any partition you back up.)
Then, using whatever partition utility you choose, recover another partition.
-- make a full image backup of the recovered partition.
Keep recovering one partition after another AND
keep making a full image backup of each recovered partition.
When I used a partition utility, I lost one, gained one, thankfully I had backups.
I had to format and re-set up my partition allotments, then restore each partition contents from its designated full image from that reliable external media.
