Can I use [System RESERVED] for backup or file storage? Because Windows 7 won't use it for BitLocker.It's only 100 MB, what would be the point?
Buy another hard drive. Save time. Save you sanity.Its better if you don't. It is an unencrypted portion of the drive, and some programs do not function well with an encrypted volume, so as such, they need a small area reserved to read/write to that is not. This is why you cannot use it for bitlocker.

Its a bit like those hidden "RESTORE" partitions or a swap file. Windows reserves some things for its own uses, and those things are not intended for user level interaction. Messing with them or causing changes in there on your own can cause all kinds of things to act unpredictably or even break all together. Consider it a part of the price that is paid for using windows, if you must.

And, again, as another poster mentioned, its usually a very small space to begin with, you wouldn't gain much by using it for storage. Quote from: seek3r on May 28, 2012, 01:26:57 PM
