Windows 10: Drive/partition disappears

Sorry if this has been covered... I searched and found "similar" issues but couldnt find an exact solution so here I am.

Setup -
2tb sata drive partitioned into C:\ (750gb) (for os / basic applications) F:\ (remainder of space 1.25tb~ for main apps\file storage)

Upon initial boot both drives are visible and accessible --- after a random time 5-10 mins rarely longer the F:\ drive or partition if you will disapears and Windows shows a ? icon in its place for shortcuts.

I intially thought I had a drive failing but again this is the same physical drive and where the C:\ partition is working just fine I have ruled that out.

Disk Manager shows BOTH partitions when F appears in File explorer but only shows the 1 partition once F drops off... which is strange to me, why doesnt it show "unusable space" or "unpartioned"etc

I can reboot and the drive comes back but again only for a short time.

Any ideas?

:)

 

Hard Drive partitions are disappeared

If it keeps disappearing it is probably a hardware failure.

But if you want to be sure you could do a repair upgrade which will clean up your windows image.

Hard Drive partitions are disappeared

Actually I have recovered the partition using the link you provided in your comment .. but I all of sudden I lost them again .. so I am wondering if it is an indicator that the hard drive is already failing and should be replaced ??

 

Hi, does the same happen in Safe Mode?

Also please download and run Hard Disk Sentinel (trial) and post a screenshot of its GUI.
To post a screenshot please use the Insert Image icon above your post to the left of the video icon. Thanks.

- that doesn't show your drive is ok.
