    Log of 'Free Space' on a Hard Disk (XPPro SP2 5.1.

    Does XP keep a running log of the 'free space' on each hard disk in a system each time the machine is booted?

    I am trying to get a handle on the used/free ratio on a storage drive not long before I inadvertently deleted the NTFS partition on the drive.

    If so, where do look for this information? Should it be in System Restore? When I navigate part way with the System Restore Wizard, I see a calendar. There are no bold face dates before the first time I took a look at this utility, which was just after I made my mistake!

    The help file called "System Restore overview" says:

    "These restore points allow you to revert the system to a previous time. They are created daily and at the time of significant system events (such as when an application or driver is installed). You can also create and name your own restore points at any time."

    The machine was set up early in March. I picked it up on 3/10/08. System Restore does not navigate to March in its calendar display. Is the failure of the OS to record any restore points an oversight on the part of the builder?

    Thanks,

    I don't know where you could find info. about used/free ratio on a drive for a historical date. And I don't know why you are looking at SR (System Restore); is it part of troubleshooting the other problem? SR only monitors some OS system files.

    However, SR do monitor (but do not log, as far as I know) the amount of free space left on a monitored drive (since it needs free space to be able to automatically create restore points in the future). If it finds less than 200 MB of free space on the system partition it will disable itself until more space becomes available. And even if you have enough free space on a system partition, if another, any, monitored (non-system partition) has less than 50 MB of free space SR will be suspended and all restore points will be purged.

    "Is the failure of the OS to record any restore points an oversight on the part of the builder?"

    No, most probably not, since the OS by default, at install time (or when you add a drive), monitors all partitions you throw at it. To disable this default behaviour you or the builder would have to disable monitoring (for one or several partitions) at Control Panel > System. And did I understand correct that you do have restore points of recent dates? If so, it can't be disabled now. But what happened before, well:

    There are some situations that may purge all previous restore points (i.e. no "bold face dates" in the calendar); install of a service pack; the above mentioned less than 50 MB space (could be a small "recovery or something partition" monitored); removal of all restore points except the most recent RP with the Disk Cleanup Tool (Start > Accessories > System Tools).

    Then of course: SR creates a RP every 24 hour automatically IF the PC is left idle at least some 5-15 minutes. But if the PC is constantly used as long as it is turned on until shutdown, well, then there's no time for SR to kick in (as you wrote there will be restore points at other "system events" also, but if no installations, driver updates etc, there will always be the 24 hour RP).

    For more info search for "System Restore" at Microsoft.

    But as I said I dont know what you are trying to do.

    The lack of Restore Points you refer to may be the result of the builder setting the amount of space allocated to System Restore to a low percentage. Right click My Computer, select Properties from the dropdown menu and then select the System Restore Tab and click the Settings button. You will find a slide bar to adjust the amount of space allocated to system restore. You can adjust this to suit your needs. HTH

    Thanks, Doc,

    I checked it and it is set on the maximum. I do not think I did anything to reset it.

    When I discovered I'd accidentally deleted the partition on a storage disk, I opened the RS Wizard for the first time. At that point there were NO Restore Points on the calendar for most of March and the first half of April. It was as though I needed to run the Wizard once to start the whole process. Live and learn. I guess it would not have helped me to recover the partition, anyway.

    I am still researching potential shareware utilities to do the recovery of the partition. Every time I look I find another.

    In the 90's a friend worked for Xchange, a consortium of folks with extensions for Quark Express. His first job was to troll newsgroup posts looking for folks trying to solve a Quark problems and then to post a 'solution' extolling an extension they represented. I do not doubt that this same process is still alive and well. It makes it hard to evaluate recommendations.

    Thanks,
