Hard Drive Doesn't Mount Its self on Boot

Hi all,
Suddenly got a strange problem with my Hard drive, it's a seagate 500gb, suddenly whenever i boot to my OS, my second hard drive isn't mounting its self a drive letter, so therefore i can't see it in 'my computer',
but then if i go to disk management, assign it a letter like Local Disk (D), i can see it again and all my files are fine,

Not sure why this is happening, happened on windows 8, then upgraded to 8.1, still didn't fix it, and now it's happening on my windows 7, fresh install

Could be my hard drive giving up?

Thanks

Check whether this resolves your problem

open command prompt
type in diskpart automount enable and press ENTER

still no luck, that command didn't help, whenever i reboot it just doesn't assign its self a letter, when i assign it, i can see it.

OK, just to make doubly sure, give only the command automount, does it say "Automatic mounting of new volumes enabled" ?(Run Command Prompt as an administrator)



If yes, then do a drive clean up as recommended here https://www.sevenforums.com/general-d...ml#post2821973 and check whether it resolves the problem

Hi, thanks for the reply, still no luck, I've ran the command twice both successfully automounting results, but still the hard drive will not appear unless i assign it a letter

This is what my computer is like on boot up,
The 64GB being my SSD, and my 500GB not appearing


Now when i assign it a letter,



But unless i assign that letter, i can't see it in my computer.

I now presume that that 500GB drive is an internal drive and since you said it had happened in Windows 8, 8.1 and now 7, it may have something to do with how your drives are connected to your motherboard ports/ controllers.

Please wait for someone conversant with such problems to help you. You may need to fill in your complete system specifications. System Info - See Your System Specs

Please restate your problem with full details with a screenshot of Windows Disk Management so that it catches their eyes and attention.. ( I was under the impression that it was an external drive. Looks like I put my finger into a wrong pot. )

Weekend morning my Windows 7 computer got the same issue when boot.

did google, the problem primarily happens on a dual-boot system. a bootloader issue.



My Win7 system is NOT running dual-boot. however, in my recent install tests, I loaded various (good or bad) drivers to test. that should be a problem. hence I restored the OS from a backup one month ago.

It's fine now.
