System Reserved drive has too much data

Specs: Windows 64

How do I reduce data on the System Reserved drive, it's at 36.7 free 99.9, thus it will not let me do a whole system backup to an external hard drive.

Not sure what your system reserved drive is, but if it is your restore partition you should have created a restore set of disks when you first got the computer. If you never did that then you may still be able to.

Once you have made those restore disks then you don't need that partition anymore.

Your original post is confusing. I read it to say you have 99.9 free. Do you mean it is 99.9% full? The restore partition normally will not have much slack space as you shouldn't be adding anything to it.

The System Reserved Drive is part of your C:\ drive and there should be no information other than the information put there when the system was installed. You should not be writing to it at all. Usually it is hidden but on some systems (mine in particular) it does appear. I can hide it if I wish but it causes no harm so I leave it.

In order to make a backup (I use Macrium and Acronis) both check boxes must be ticked. If you don't your backup will be incomplete and your system wont boot after a restore.

I believe Ewen is correct. The "System Reserved Drive" that you're referring to is most likely the 100MB boot partition that's created when Win7 is installed. It does not have a drive letter & should be hidden. What software are you using to create the backup?

That's correct it should be hidden (for some reason mine was shown and it has the drive letter H) but backup programmes show it as a separate drive regardless and the check box next to it is never checked so to create a successful backup both the Reserve drive and the C:\ drive should be checked otherwise the system will not boot.

My drive is 67.7mb free of 99.9mb. The OP should note that it is megabytes not gigabytes

36.7 of the 99.9 is used. I did make the recovery disks.

"I was trying to copy to an external hard drive"

Are you using backup software or not?

This is the address for Macrium Free: it is by far the easiest to use and if you follow the directions given above you will have trouble free back-ups. The Windows back-up works but it does not copy the Reserved Partition. Also note that the Reserved Partition has nothing whatsoever to do with the Restore Partition. The Reserved Partition is involved in the boot process. The Restore Partition will help you restore your computer to factory condition in case of a severe system failure.

SR does store other data, such as hibernation data (not the raw data, but apparently meta data), and other progs do write to it occasionally. You can explore the partition via a Linux boot disk (I rec Puppy) and delete what isn't necessary. But be careful, because what is necessary really IS necessary, or you'll break your boot. I would do an image of the partition and also burn a Windows repair disk.

Or you can expand the partition to make more room, or possibly turn off hibernation. Or just use a third party backup prog to make the image.
