Windows 7: New drive including partitions (F:, G:) appeared.

03 Jun 2013   #1

Windows 7 Home Premium 64bit
New drive including partitions (F:, G:) appeared.

So today when I started up my PC, windows suddenly wanted to do some drivescan on startup. It started checking and indexing files. I thought this had something to do with the fact that I had reinstalled Windows the day before.
Ive tried it twice and both times the indexing froze halfway. Once at 59% and once at 77%. I assume it froze since nothing happened for over 20 minutes each time.
The third time I decided to just skip the scan.

When my pc booted up and I went to check on my drives (since the indexing got me curious) there suddenly are 2 new ones. One drive is named Local Drive F: the other one is named Boot G:
The F drive has 84,7 MB free out of 99.9. When opened up it shows no files.
The G drive had 31.9 GB free out of 58.5 GB. It contains Program files/Windows folders.

Is this something I should worry about? I have no idea why they are there or what their function is.

F is the Windows 7 system reserved partition. It normally wouldn't have a drive letter and be hidden. It would only show up in disk management. You should be able to remove the drive letter with no side effects. Right click that partition and select "change drive letter and paths". Then click remove. G may be an OEM partition that also shouldn't have a drive letter. I can't say for sure but that's my guess. System reserved has recovery utilities, etc on it. Now that it has a drive letter it will be indexed and accessed by system restore. If enough restore points get saved it will eventually run out of space and you'll get a low disk space warning. Same deal for the other drive.

F is most likely "system reserved", although it hasn't a label. G is most likely an old winOS. You have 2 disks in the system, you must remember you did install windows on it before.

Thanks for your replies!

My C: drive was actually used to store my old WindowsOS I think. Anyway, I havent done anything since I made this post besides some gaming (no reboots or anything) and suddenly the drives have dissappeared. They dont show up in Disk Management anymore either.

What I did do is stop windows from indexing in the future.
I was told that when im not using the search function all that much, I might as well stop indexing.
Would that be considered wise? Or would it be better if I turned it back on?

You can delete volume F and G in disk managerment if you are sure you never use them. Delete the OEM partition as well. F, G and OEM aren't involved at all in the boot process.

Once you move the data off and delete F and G in Disk Mgmt, I'd partition it Logical to keep it from derailing the boot files from C if you ever do a repair or reinstall. Partition / Extended : Logical Drives - Windows 7 Forums

This is why its best to have your Win7 drive always in the DISK0 slot, set to boot first. You can move it now if you want, or if it's easier partition the data drive Logical so it can't accept System Boot files.
