D and E drive keeps disappearing? any fixes?

Hi,

Go to Disk Management, click “Action” on the toolbar and then select “Rescan disks” to let system perform a re-identification for all connected disks. See if the D drive will appear after that.

Hope this helps

Hi:

I, too, am having trouble with my D: drive disappearing. Sometimes, a shutdown and restart will make the D: drive visible again, but it'**** or miss.

I've saved a cem.evtx and cem.nfo file here:

Any advice would be most appreciated.

Thank you!

Possible reasons these are not in order I just listed them for you.

1. Windows update is being pushed out.
2. Infection or Software corruption going on
3. CMOS battery need replacing. 
4. Cable connection to the device is lose worn or frying 
5. Hard disk is faulty at a concern sector.
6. Worst case the motherboard is on its way out.
7. Memory stick (RAM) need reseating or is its way out
8. another device incorrectly received update for it or faulting.

9)  Power supply unit is at fault

10. Disruption to the power supply has caused system corruption to occur.

Carry out basic checks make sure you have good power supply and cables are corrected firmly,

Check your system log events and or Security maintence for possible update that may have incorrectly been applied or trying to be applied.

Carry out any virus checks to see if its computer virus, spyware etc issue.

Carry out checks of ram, cables and connections inside the computer.

Replace CMOS battery as you should do that every 3 to 6 years.

Maybe reformat and set up is need do as a last resort.

Worst case new hardware.

Can try assigning both drives different letters in Disk Management then check to see if they still disappear?

Press Windows key + X

Click Disk Management

If you see your drive listed there, right click it

Click Change Drive Letter and Paths

Click Add

Click Assign the following drive letter

Click in the Drive letter list box



Choose a drive letter - try choosing letters near the end of the alphabet

Click OK

Click OK again

Are these local drives or partitions?

What is the exact make and model?

Open Start, type: system information

Hit Enter

Click System summary

Look in the right pane

Copy the system sku info into reply here.

See example: https://imgur.com/qzektpA

if its a custom built computer, what is the make and model of the motherboard?

Try resetting your BIOS defaults:

If that does not work and you have a desktop computer...

Power down

Unplug it

Open the system unit

Remove the CMOS CR-2032 chip

Plug it in, start the machine, wait 10 seconds

Power down, unplug it, reinstall the CMOS CR-2032 chip

Plug it in again, power up
