Hi all, hope someone can enlighten me. My 40GB C (NTFS system healthy) drive suddenly started showing as only 34GB. Had a look at disk management and saw there is an unknown partion which has no label but is reported as '3.00 GB Fat32 healthy (Unknown partiton)'. On right clicking it the only option is to delete.

I have done no partioning or anything that I can think of to have created this. The only new things I have been doing is using flaskmpeg to convert a ripped dvd to mpg. This was a very slow and heavy process. The problem appeared soon after.

Hope I am not missing something simple?

Thanks,

HT

It's most likely that one of the ripping programs has decided to use this drive as a virtual drive for ripping purposes.
Look in Device Manager (Start...Run...type in "devmgmt.msc"(without the quotes) and press Enter) for any new, unexplained drive entries. If that doesn't identify the drive, then the hunt for it's "owner" will be a lot more difficult.

Post back with the results of your search and we'll go on from there.

Hi John (or Mr. Cranky Pants),

Thanks for your reply. I could not find find any new entries :thumbsup: I would expect them to list under disk drives in the 'devices by type' view?

Yep, I've had several DVD programs do this to me.

What's the exact make and model of your system?

IMO there's several ways to approach this problem.
1) Leave it alone if the space isn't needed
2) Attempt to access the Unknown Partition and see what's on it (IME the most common thing is that it's a recovery partition for your computer)
3) Start removing programs until it either goes away or you run out of programs to remove.

Two other things that may relate:
- disk imaging software may create a partition to store recovery information (Acronis True Image, Norton GoBack, PCAngel, etc)
- installations of other operating systems (such as Linux, BeOS, etc)

I will try deleting programs in reverse order to intallation and see if it clears up. Would like the space back as I have only 10GB free at the moment. If I just delete he partion will it be gone forever or can it be rocovered back into C?
If it is a recovery partion will it revert to C in time?

I have used no disk imaging software nor installed any other O.S.

Thanks again for your help here!

It's being a Dell may complicate things further.

Does your Dell have an option to do System Diagnostics or a recovery when you first boot it? Do you have all the disks that came with the computer?

I suspect that this is the system recovery partition for your Dell - and wiping it out will prevent you from being able to recover in the future. I'd suggest that a good, external hard drive would be a good investment and would leave this partition alone.

But, if you've got the recovery disks, you can delete the partition and regain the space - that'll just make a recovery (if needed) a bit longer.

A final option is to purchase and install a new, larger hard drive - and use the restore disks to restore Windows to that. Then you'll have all the extra space that you need without having to have an external drive to tote around with you.

Good advice,

have an external hard disc with lots of space but as you say sometimes don't want to hump it around.

Dell came with no recovery discs but there is a recovery option from boot up (f12)

If I delete the partion then try recovery at boot I might find it available again?

I will try your sugestion of removing programs first. Then move to the recovery attempts.

Thanks John, will keep you informed.

Seconded. That sounds like it's almost certainly your recovery partition. Not certain why the change in drive size reported by windows. I know it might sound stupid, but do you know for sure that Windows reported the drive as being 40GB in size beforehand?
Due to the way hard drives are designed\manufactured\formatted, it's usual for Windows to give a smaller drive size than the drive is labelled, especially if it's formatted as FAT32.

OK that sounds like good advice, will leave all alone for a while. The drive of course never reported the full 40GB (37.5) but dropped by 3 GB (exactly the size of the new un-labeled phantom partition.

Recovery partitions are preloaded at the factory and don't just show up or create themselves, especially in disk management.
They can be hidden from my computer or explorer.

the fat32 is so the partition can be accessed from dos

No. Try not. Do... or do not. There is no try.

But it has no label and just appeared in these last few days? How can I access it from dos with no volume label?

I am starting to think it is not the pre-loaded system recovery partition. I neglected to add that there are 3 partitions showing;

78MB FAT Healthy (EISA Configuration)

C: 34.17 GB NTFS Healthy (System)

3.00 GB FAT 32 Healthy (Unknown Partition)

This last one is the new arrival... Maybe flaskmpeg made it while I was converting the DVD?

Could very well be it - do you use the Restore It software mentioned in the article?

Not sure if this is any help but the last time my son reformatted my PC my drive dropped from 120GB to 107Gb. Turned out that in BIOS a setting which should have read 130hz had reverted to the factory default of 100hz. As soon as the setting was changed it showed the correct amount again.
Motherboard: Gigabyte GA-MA770T-UD3, CPU: AMD Athlon II X3 450 Processor, Memory: OCZ 4GB (2x2GB) DDR3 1333MHz,Graphics: PowerColor HD 5750 1GB GDDR5,
