Windows 10: Drive Letters, will they be overwritten or reassigned?

Newly (clean) installed Windows will again reassign letter in the order they appear in BIOS, Ie. the places connected to disk controller.
Something like this:
SATA0 >C:/ (Where OS is installed)
SATA1 > D:/
SATA2 > E:/
Etc. Etc.
Partitions (with a letter) may drop in somewhere in between.

 

Thank you again. I appreciate it.

I want to make sure I am following correctly. My HDD's are external and will be plugged into a USB Port, with that said will they appear as you showed?

To make sure here because I think I almost got the light bulb going off*Smile The OS will definitely forget the drive letters of I and J before the clean install? I am guessing yes of what you said earlier that it will reassign probably to E and F and then as I plug in the other HDD's it will assign G H etc etc.

 

Removables may behave differently but also in order of appearance. If you give each disk a name it will stick with it until reformatted and name changed. Also when you format a disk it gets own serial number. You can track them on those two parameters.

 

What works for me if I want my external drives to maintain the same drive letter each time they are plugged in is assign them letters high in the alphabet so there is little chance another drive will take its drive letter. For example, I have 3 external drives I use frequently. I gave them drive letters of W,X and Y. Every time I connect them they always have the same drive letter. As Count Mike said, they get their own serial number and the computer will remember as long as no other drive has taken its place. Not likely to happen with drive letters such as X.

 

+1 essenbe -- as long as one plugs those usb ext devices into their same respective usb ports, they retain their assigned drive letter.

 

Thank you for that information. Helpful.

 

Thank you!

 

Well Everyone, I want to give a big THANK YOU *Thumbs for all of your help. I think I am good to go, but if there is something I remember to ask I will post or anything else that I might be missing or something you still would like to share please do.

I hope everybody had a great weekend.

 

I hope you have your issues fixed. If not, we'll be right here.

 

Thank You! Hope to see u in the next thread!!!

 

If you want to start anew to set letter order for removable devices you could use: Download Device Cleanup Tool - MajorGeeks to clean up old settings buy removing those USB drives from the list. They have to be disconnected at the time.

 

Thank you! This could come in handy. I appreciate it! Hope you had a great weekend!

 

No probs, I'll have even better Monday, my granddaughter's first birthday today.
