Windows 7: Hard Disk Partition Letter Missing in Windows 7 - Fix

What if the option "Change Drive Letter and Paths" is greyed out?

Hello Longnh, and welcome to Seven Forums.

Could you post a screenshot of your Disk Management showing all of your drives layout?

Hey Brink, thanks for your quick reply.

I'm using dual XP and Windows 7. That partition (F didn't show up in Windows 7 though I can still see it in Disk Management (the only information is total size, there's no label, letter, free space, used space). When I right-clicked, "Format" was the only option available in context menu (Disk Management). Everything's normal in XP, I mean I can read/write to that partition if I boot into XP. It's so weird.

After I formatted that partition, it works well now (so I cannot take any screenshot). I can see it in both XP and Windows 7 (but my data was gone, of course). Basically my problem was solved, but I'm still curious about this error.

Longnh,

I'm not certain what was the issue, but I'm happy to hear that you got it sorted.

Hello Bajol,

Do you have access to them to be able to copy the files to another location, then format them to get a drive letter and copy the files back?

No I can't acces it..
In this case, i'm login as administrator. But I'm still can't acces both of them.

My only way is acces the drive from XP and backup the files from there.
i have formatted HDD through 7 disk management and 7 can recognize now

thanks for the advice

You're most welcome Bajol. I'm happy to hear that you got it sorted.

Brink:
I am having the same problem. When my XP died I bought a HP running Windows 7 Home Premium 64. While most of the files I wanted are backed up to a portable hard drive, I thought the easiest way to move my files was to remove the drive from the old computer and put it in the new and drag and drop the files where I wanted on the new one. I then planed to keep the drive in for storage and backup.
(I was not planning to duel boot to XP as I understand that windows checks and does not run on different computer, but if it is possible I would be interested in doing so)
I have followed the steps listed to add a hard drive. I have scanned for changes. I have uninstalled and reinstalled the drive in Device Manager. I have changed folder options to show hidden files.
I do not want to reformat the drive at least until I transfer some files off it.
Any help you or other forum members can give will be greatly appreciated.
Thank you very much.
Ben
