Corrupted CPD file in RH7 (again)

I've had this ongoing problem that rears its ugly head every
two months. My CPD file continues to corrupt when it reaches 1500
KB. This project was originally built in X5 and then we upgraded to
RH7. I initially would compress this file using MS Access. Then
when it grew to 1500 KB it would corrupt again. So two months ago I
deleted the CPD file and reopened the project using the XPJ file.
All the links were broken. I painstakingly fixed all the links over
a two-day period- thinking this would fix it once and for all. Now
it's corrupted again. What can I do to fix this permanently? Why is
it continuing to corrupt? Is it necessary to compress this file
periodically?
I also tried renaming the the CPD and XPJ files and then
opening the project using the HHP file. This also leaves the
project with many broken links- but maybe these links are broken
because RH is not seeing the folders for these topics in RH but
they exist in Windows Explorer (I have Peter's instructions on
remedying this). Again, my main objective is to find a permanent
solution to this problem- if one exists. Thanks-
Cheers

GEWB,
Well, the folder I deleted was a user-created one that my
boss had made. But here is an example: the project had a folder
called "Authorizations" in Project Manager. But when I opened the
project folder in Explorer, there was the Authorizations folder,
but then another duplicate folder with that name was inside a
folder called "Online Help". This Online Help folder had just odds
and ends thrown in it. What it would do though is cause RH to break
the links to the legitimate topics in the Authorizations folder and
this folder would not appear when I rebuilt the project. Because
this folder existed on two levels, it seemed to confuse RH so it
would leave it out all together. When I deleted this unnecessary
folder, the project rebuilt without any problems. So I think it's
important if you inherit a project to make sure there aren't any
residual folders that might conflict with existing ones. Hope this
helps-
All the best,
Rich

RoboHelp building corrupt CPD files?

My coworker and I are trying to get Visual SourceSafe up and
running on her machine with RoboHelp so we can both work in the
same help project. We've got it working great on my machine (I
built the source control database from the help project on my
machine). We got the files down to her machine, but when we open
the help project, we get an error stating that the CPD file is
corrupt and we should delete it and reopen the XPJ. We did that,
and we got the message again, but when we looked at the directory
to delete it, we found that RoboHelp didn't even rebuild the file.
The error occurred before the file could be built.
It appears that the CPD file does not reside out in the
source control database. In other words, I have a working CPD file
on my machine, but it does not get checked into the source control
database. When we got her files the first time and opened them in
RH, her RH tried to create a CPD file and was not able to do it
successfully, so we got the error.
Here's my solution and a further question: I copied the CPD
file from my machine and sent it by e-mail to her, and we were able
to open the help project and RH successfully retrieved topics from
VSS. However, I wonder if there's something wrong with her
RoboHelp? It looks to me like her RoboHelp is not able to build CPD
files correctly. If that's so, can we expect other problems (maybe
it won't be able to update the file correctly either)? Should we
uninstall RH on her machine and reinstall it? If there's something
wrong with RH on her machine, I'm concerned that we'll keep having
problems after she starts making changes to topics.
If anyone can help, I (we) appreciate it.
Thanks!
Lisa

We are having similar problems with RH and VSS. It seems to
be especially a problem on my machine - anything I do seems not be
written to the VSS database. I noticed today that the CPD file
version on my machine is out of sync with the database version. We
have about 40 projects of varying size. However, the problem is not
isolated to a single project or seem to be related to a
specific-sized project. Certain projects work fine, and certain
ones are consistently troublesome, and some give intermittant
problems.
In one project, the CPD appears in the VSS database, and I
must check it out from the VSS interface first (I finally got my
local copy synced with the database). In another project, the CPD
does not appear in the VSS database, and I'm not sure how to sync
the two. To make matters worse, it appears that I don't have an HHP
file in some of the local folders (there is an HHC and HHK file -
but the HHP does appear in some local folders).
It appears to me that each of us has some local settings that
are overriding the database settting - I can fix my local copy, and
it will work fine until one of my co-workers opens it and makes a
change. Then everything gets out of sync. The result is that I have
to import missing files (they still appear in my local folder) or
"unpurge" items in the database. The problem keeps recurring no
matter what I do.
At one point, I fixed the project on my local machine,
deleted the VSS version, uploaded the fixed project, and had my
co-workers remove their local versions and re-downlead the new
copy. It worked for a couple of weeks, but we're right back to
having issues.
As far as I know, everyone always gets the latest version
each time they open a project. We don't have administrative rights
over the VSS database (we share the software with the developers),
so we are limited as to what we can do, but the syncing problems
are a serious issue. I've found several times that my work has been
wiped out, and the constant re-importing topics, patching
databases, and recreating work is has caused me to fall behind on
my documentation projects.
Any assistance will be greatly appreciated.

RH9 error: .cpd file corrupt

I've just received this error for the second time. The first time I "tried deleting the .cpd file and reopening the project. All the topics were missing -- each topic name was in the project with a red delete/broken X across it.
After vainly trying several approaches to getting my topics back, I decided to start over. The original project was converted from RH7. I decided to create a new RH9 project and import topics. That seemed to be working well, except two topics would not import. Each caused RH9 to lock up with a "busy" hourglass and when I closed RH9, I got the Windows XP SP3 "not responding. End now?" error.
So I created new topics in Dreamweaver and pasted the text into them and imported the new topics. I use Dreamweaver as an editor; I am not fond of the RH editor -- a totally different conversation. (Likewise, the RH9 conversion of RH7 projects is a totally different conversation.)
With all topics now in the project, I started to rebuild the TOC and completed most of the TOC when RH9 locked up again. When I tried to reopen the project, I got the error shown below (again). Is there a way to remove the corruption from my .cpd file? Should I totally give up and go back to RH7?
This project has between 300-400 topics and about 1250 files in the compiled version. We're using both conditional build tags (4 builds) and user defined variables (also 4). I have discovered that the RH9 codes for both build tags and user variables are different from RH7 (and they didn't convert) and have begun the process of recoding the first section of the project. Should I not attempt to import a topic into RH9 until after all the codes in the topic are updated to the RH9 version?
Does this issue have anything to do with the new RH9 doctype code that automagically applies itself to any topic that is opened in the RH editor? From what I've read, I do not want to use XHTML and want to stay with the HTML doctype I've been using with this project. We compile WebHelp and deliver the Help with web-based applications. A sample of the RH9 doctype follows.
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
 "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
I hesitate to do anything more without guidance. Rebuilding this project again is a discouraging thought.
Thank you for your response and advice!

The missing sample in the previous was supposed to show the HTML code I saw in both RH7 and RH9 for build tags.
 RH7 HTML looks like: ...text goes here...
 RH9 HTML looks like: <? rh-cbt_start condition="NATL" ?>...text goes here... <?rh-cbt_end ?>
The HTML for user variables is similar in both RH7 and RH9. Neither the build tag or user variable code converted during the RH7 to RH9 upgrade -- for me.
Is the HTML code for RH9 build tags (shown above) actually XHTML? It occured to me that perhaps adding an XHTML code into a topic that has a doctype for HTML may be an issue. After correcting the build tag code in Dreamweaver and saving, I closed DW, opened RH9 and did File/Save All. I don't think the doctype changes to XHTML in RH9 unless I import the topic again. Just wondering if that could be part of the problem. Last night I sent a small test project for deploying in the web site test environment -- to see if our web app will handle XHTML documents. Testing is necessary since the "new" RH7 charset utf-8 was not compatible with our web app either. (That was a big struggle to get resolved as well.)
I will contact IT today about a second login profile for my computer. My coworker is working on a different project in RH9, but it does not include build tags or user variables and she has not experienced crashing and corrupted .cpd file.
thanks for your help!

Robohelp 9 Corrupt CPD When Moving Files

Hello all,
I made a brand new file in Robohelp 9. I made it locally and moved the entire folder to the fileshare. When I tried to open it from the fileshare, I got the error that the file was corrupt and to delete the CPD file. I delete the CPD file and that fixes the issue. However, whenever we move it from the fileshare to our local drive or back again, the file gets corrupted again. Every time.
This happens to me and to other folks on my team. We had the same issue with another file a few weeks ago.
Is there some trick to moving the folder that I'm missing? We are on the cusp of building a much bigger project so I can't afford to lose my project to a corrupt file.
I made a folder called ProjectSourceFiles and put the robohelp files all inside that one folder. We are moving the big folder.
Thoughts?

You cannot run projects from a network other than with source control. The reason is explained in Snippets on my site.
You can store the projects on a network for backup purposes but you cannnot run them from there. If there will only one person working on any project at any one time, use the project locally and run a simple backup routine at the end of each day or overnight. I prefer to create a zip file and copy that. The backup adds some date information if we need to step back.

RoboHelp 8 - how to resolve rhbuildtag.apj/.cpd file errors?

Hi there,
I’m using RoboHelp 8 (with service packs, version number is 8.0.2.208). There are two writers on our team (in separate offices) and we use SVN (via Tortoise SVN) to version all our source files. Our Online Help is comprised of about 30 individual help projects that we merge at build time. We work locally on our own machines and commit everything to SVN each evening.
We (mainly me) have had ongoing problems with .cpd files getting corrupted (I’m in the company 5 months). I’ve followed all the good advice I’ve seen on forums about renaming/deleting them and letting the affected RoboHelp project re-create it when I start it up again. This has worked until now.
Also note, that I got a new machine early this week and I brought all our source files down successfully from our SVN repository after we installed RoboHelp. Happy days.
Yesterday in one Help project I received the following error messages and noticed that the Conditional Build Tags were not listed in the CBT Pod, despite being present in the topic themselves.
An error occurred while trying to read data from <Project Path\Project Name\rhbuildtag.apj> <1>
Your project file, C:<Project Path\Project Name\project.cpd, is corrupt and cannot be opened. Try deleting this file and reopening the project.
I consulted with my colleague this morning and his local project is fine – all conditions present and correct and no CPD error message. He committed his project to SVN and I updated but still no luck.
Despite having the latest versions from our repository anyway, I tried copying the contents of his rhbuildtag.apj file to mine but that made no difference at my side. I renamed/deleted CPD files several times over but project still won’t open. I deleted my local working versions of all our Help projects and brought them down from our SVN repository - twice. No luck.
I’m flummoxed as how to fix this project/restore conditions to CBT Pod?
Why would I have ongoing CPD issues and my colleague not?
My colleague is offline until the morning (different time zones) so will catch up with him then again. It seems to be something very local to my setup.
Many thanks in advance for any wise words offered.

Hi folks,
Just to let you know that we resolved our problems with our misbehaving rhbuildtag.apj and .cpd project files.
As I mentioned previously, my colleague's version had been working fine. This was the very puzzling bit as I was pulling the exact same set of project files from our SVN repository.
Since yesterday...
From these forums, I discovered the 'Clear project cache(.cpd) before opening any project' check box in the Tools > Options dialog. That wasn't selected in my troubled project (was able to get into the project earlier in the day). It was selected in other projects so selected it but it made no difference.
I then asked my colleague this morning to check if that check box was selected on his working copy of the project, reasoning that maybe if it was selected on mine and not his, it could cause some kind of disparity.
Wrong move. Very wrong move. Clearing his cache file caused him to get the same errors as I had got. So while we had the exact same rhbuildtag.apj file, there must have been something in his old cache file, keeping this error at bay. We don't version the .cpd files so his file would have been particular to his local working version of the project.
So another step back - now a corrupt project at both offices.
I then took another look at the contents of the troublesome rhbuildtag.apj file. I had noticed yesterday that there was something funny about one condition that I added back in October - a condition based on a release number (6.3.12). There were two instances of it in the file - looked to be saved twice though the condition was only ever added once and displayed once in the project CBT pod. See the attached screenshot. Also There was some markup around it that didn't make sense, looked like the file had saved badly. I compared it to other working build tag files in other projects (and while the conditions would vary slightly across the projects, they should be very similiar. I saw nothing like it.
I saved the contents of my file locally (though being versioned in SVN would have had a backup anyway).
I deleted out one of the duplicate 6.3.12 conditions and removed the funny mark up.
And lo and behold our project opened successfully.
I commited my changes to the rhbuildtag.apj file back to SVN. My colleague updated his version and his problems too are resolved.
Root cause:
Looks like our woes were caused by a corrupt condition in the rhbuildtag.apj file, which then caused the .cpd file to crash.
Resolution:
Identified duplicate condition tags and superfluous markup in the rhbuildtag.apj file and remove them (after making a copy). My previous machine was terribly slow and RoboHelp oftened crashed due to the poor machine performance. This could be one plausible cause for the corrupt condition.
Given we added this condition back in October, I'm not sure why the problem only cropped up now as we would have made changes to the project since then. But such is RoboHelp and our daily battles.
Hope this info is of help to someone out there.
Thanks for all the replies - much appreciated.

Corrupt Dock File?

Hi,
So on my dock, I have my Applications Folder on it to use as a shortcut, but just recently, it started to display two of every application. See my picture:
I also have my Downloads Folder on my Dock. When I drag things from the Downloads folder into the trash can, nothing happens. But then when I click +Show In Finder+, it shows the file as deleted.
So it seems my Dock is not refreshing or something? So what I did to fix it was just remove the Applications and Downloads Folders from the Dock, and drag the Applications and Downloads folder from my hard drive to the dock. But everytime I log back in or download something else, the problem will arise again.
Do I have a corrupt dock file? I didn't want to try messing with that until I consulted +Apple Discussions+ first.
Thanks, Alex

if recreating those stacks doesn't help try resetting your dock preference file. delete the file /users/user/library/preferences/com.apple.dock.plist and enter the following terminal command
killall Dock
your dock will be rest to the default. see if the problem goes away.

Thread was also opened on the Mailing list:
Here is the answer
Hi,
in most situations an "add log volume" does not solve
a log full situation, because the added logvolume is
accessible first at the moment, when the write position
on the log is at the end of the old logvolume.
If a LOGFULL occurs, the save log!
All "parts" of the LogVolume are numbered and each one
has stored the identifying number of it's predecessor and
it successor in it's header-page. The message
     "Linkage missmatch between volume"
means, that these values does not match any more.
Did you somehow changed the contents of this file/device?
If so: can you revert the change? Then the restart should
work again. do a logbackup and your database will run again.
If this doesn't work for you, you could patch the
header pages of the logvolume (I assume you do not really
want this).
Another way to solve the situation is to do a data backup
in admin-mode, reinstall the database and recover the
databackup, because the removal of a logvolume is not
supported.
kind regards, Martin

My Vista system crashed due to a corrupted windows file. When I reformatted C:/ & reloaded firefox & tbird, my bookmarks were gone. I have an image of the drive , but I don't know how to recover them and get the data back where I can access it.

Vista system crashed due to a corrupted system file. The C drive was reformatted, and windows reloaded, along with the rest of my programs.
Before the drive was reformatted, an image was made of it on a USB drive to save all the data. Now I need to know how to get the Bookmarks back for Firefox, and the Address Book back for Thunderbird.
Thanks

Thanks for the quick response. It worked very well, for both Firefox and Tbird.
One hitch, until I remembered: those are all hidden files, in hidden folders. I had a devil of a time finding the "roaming" folder, until I found out how to unhide everything. In years past, I used DOS for that kind of thing. Explorer is much less user-friendly. Now that I know how to do it, it's simple.
Thanks again for the guidance

Installed Photoshop cc 2014 asks for serial # - corrupted Windows file permissions

More of a warning / heads up to all than a question - installing Photoshop cc 2014 [via the CC manager app] caused some Windows file (security) permissions to become corrupt corrupt on my system. Symptoms include cc2014 asking for serial number validation on startup (when, as a cloud version, it should not do so), then being unable to connect to the internet when you press the 'validate serial' button so getting that window into infinite loops, and - a real pain in the *** when trying to fix the above - causing abends of some windows shell functions that in turn cause windows explorer to crash and restart.
Anyhow, digging into this (fortunately, I am a long time Windows SysProg) I discovered that for reasons unknown, either the CC master app or the actual Photoshop cc2014 installer (or both) are changing file access control permissions on a number of files, mostly DLL's. Most of the files affected are in the (normally hidden) Program Data directory on the windows root disk, Some of them are in the Adobe subdirectory - so fair enough if they want to fool around with their own program - but others being changed are in the Common Files and Microsoft subdirectories. I cannot for the life of me figure out why this is necessary nor why Adobe feel the need to touch files that 'do not belong' to them - something dangerous in the extreme as an external app such as Windows Update might replace or 'repair' the files so touched, and if Adobe / CC are relying on file permissions on non-Adobe files, such changes could result in all manner of random and spurious problems / error messages occurring.
Anyhow, if, fellow Photoshop cc 2014 user, you get this happen to you then you can fix the file permissions by opening a console window [also called a "DOS box", or "command prompt" depending on your age and knowledge... 8-) ] and run the windows file checker with the command
"sfc /scannow". Make sure that you use 'run as administrator' to open the console window, or you'll get an error about sfc only being available to administrators. Also a very (very) sensible idea to close all non-essential running applications first to prevent any possibility of weird interactions happening.
Finally, check that the 'hosts' file in [root drive]:/Windows/System32/drivers/etc is valid - for some reason, it looks like the install tried to check or update this file (again, I have no idea why) but the result was a corrupted hosts file, which I assume is the root cause of the 'unable to connect to host' type internet error messages. Copy the file, rename it as 'hosts.txt' and edit it with notepad or wordpad. Look for lines containing garbage strings at the bottom of the file (any line that starts with a # ignore, it is a comment, and any line that has IP addresses or host names should be ignored - though if they reference a site such as "someserver.adobe.com" you might want to treat them with suspicion if you continue to get internet 'cant connect to site' type errors.
Anyhow, when I fixed these two sets of problems, Photoshop cc 2014 started 'right first time' without all the BS messages about serial numbers etc.
Hope this helps somebody out there in AdobeLand......
Rick

Update: I tried several times to reproduce the error, actually it dosen't occur. I changed nothing on my system, without reboot it twice. This is what I said in my beginning times: it occurs sometimes but often. I will keep you up to date.

Error message says I have to delete a corrupt backup file?

Error message says I have to delete a corrupt backup file, but under my preferneces & under my devices, there is no old backup file to delete, so I can't delete a corrupt one if i dont have any?!

I know this is a late reply was wondering if you had the problem still as I have been having this problem for many months. Today I was looking around getting ****** off why it was not working and I found my culprit and thought I would see if it would help you. Not sure if you, like me, changed your itunes media store location somewhere other than the default location. What I noticed was in Users>UserName>AppData>Roaming>AppleComputer>MobileSync there was a backup folder with a shared link icon on it and when I double clicked on it windows promptly brought up an error that its location was not valid. So I figured since it was not valid and I did not have any backups anyways I deleted the folder and then went to itunes and tried a sync and it worked perfectly again. The backup folder was re-created properly and the stupid corrupt error went away.

Cannot open corrupted .mov file - error 2048 unsupported format

Hi all,
I have an important corrupted video file and I have tried every way I can think of to open it, but to no avail...
When I open it with Quicktime, an "error 2048 unsupported format" shows up, even though other videos I took are fine.
I can't open this video with ANY softwares including VLC and friends (trust me, I tried LOADS of them)..
After doing MUCH research I understand that either the header/closing part of the file is messed up.
Is anyone able to teach me how to fix those parts?
I'm really at the end of my wits and I'm a just beginner to hex-editing @.@ Better still, if you are able to take a look at this video for me...
I'll be very glad if anyone can help me out with this as I really wish to recover the video, this is for an important friend, thanks in advance!
P.s. the video is about 120mb in size

Hi
Im using the tool called SUPER.
Its free and you can convert any file format to any other file format
Maybe it would be possible to convert his faulty file to another format and ten you could try to open it again using VLC player or other application.

"zip" Terminal command no help fixing corrupt zip file; any other workarounds?

I downloaded a ".zip" file containing some files that I need to access.
When I double-click on it, I get the "Unable to unarchive 'xyz.zip' into '[foldername].' ( Error 1 - Operation not permitted )" message, which many people report when they try to open a corrupt zip file.
I also tried opening the file with "StuffIt Expander," "Archive Utility," and "The Unarchiver," as well as some specialty zip-compression programs, but none were successful.
I then installed the very useful "Archive.qlgenerator" plugin (http://homepage.mac.com/xdd/software/archive/) which allowed me to at least see inside the zip file using OSX's "QuickLook" feature. Lo and behold, all the files that were supposed to be in the zip file are indeed in there, as they should be. The problem is not that the zip file is empty, the problem is that it has become corrupted somehow.
So, what I need to do is either "fix" the corrupted zip file, or alternately find some way to extract the needed files using brute force.
Following tips given on various forums, I tried using OSX's "zip" command in terminal (http://homepage.mac.com/kelleherk/iblog/C1901548470/E731143104/index.html and http://hintsforums.macworld.com/showthread.php?t=132146). I was able to use it properly, but unfortunately neither the "-F" nor the "-FF" commands were of any helping in "fixing" the zip file. The "-F" command incorrectly said that the zip file was empty and that there was nothing to fix; the stronger "-FF" command came back with

    e      (end this archive - no more splits)
    z      (look for .zip split - the last split)
or ENTER (try reading this split again):
...but none of the options produced any result. Pressing "z" gave me
Could not find or open
xyz.zip
...which means that even "-FF" could not get past whatever problem had corrupted the file.
So: is there any built-in way for Mac OSX to fix or extract the contents of a zip file corrupted like this?
Alternately, is there any third-party shareware or freeware that will do the trick?
(I don't want to have to spend big $$$ on a commercial program since all I need to do is open a single zip file. And there is no way to contact the zip file's original creator, so I can't download an uncorrupted version.)
Any help would be greatly appreciated.

Mark:
When I try your first suggestion in Terminal ("unzip -t /path/to/file"), I get this message:
Archive: /xyz.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of /xyz.zip or
        /xyz.zip.zip, and cannot find /xyz.zip.ZIP, period.
When I try your second suggestion ("unzip -l /path/to/file"), I get the exact same error message. (And yes, I am fixing "/path/to/file" to be the correct path to the actual file).
And no, it is not really part of a multi-part archive. (Or at least it wasn't supposed to be; only one zip file is available, and there was only supposed to one.) Perhaps the zip was mis-encoded in the first place, so that the person who created it accidentally did something wrong which the unzip applications are interpreting as this file being part of a multi-part archive; but even so, all I have is this one file, so I need to fix it as is, or extract its contents as is, since I have no way to contact the original creator to do it right this time.

Writing metadata to originals is corrupting my files.

Hey guys,
I am using Aperture 3.3 with 10.7.4. I am importing my files, but they are not being copied into the library. I am leaving them where they are. Next I add keywords to them and then use the command 'Write IPTC metadata to originals'. Doing this is corrupting my files. I am getting an unsupported file format warning in place of the files. When I go to the files in Finder, the files are junk. Thankfully I backup my photos before doing anything to them so no harm done this time.
Thanks
Jason

Hey Owen,
Thanks for replying. I just now tried again and the same thing happened. Now the first time I tried Aperture I stopped thinking something was wrong and I didn't want to mess up my files so I just continued using Picasa and iPhoto. This time I did the same thing, but came here and posted my problem. And after reading your reply I decided I probably should try some other folders full of photos. And guess what....no problems. It appears this one particular folder full of photos is somehow messed up and when I write the metadata back to the files they get corrupt. They are jpgs from 2000 and the camera was a Toshiba PDR-M3. Now other photos taken with this camera are working so it must be something with this set of photos.
Thanks again.
Jason

10.4.11 disk utility says, OK. Disk Warrior says many corrupted plist files

I had been doing a permissions fix with disk utility and when I restarted, my entire home domain was GONE.
Disk warrior got it back, but DW says a big list of plist files can't be fixed
Address book won't open.
Is this the beginning of a fatal drive melt down?
Can I just toss all the corrupted plist files and retart>
Thanks,
Ty Ford

Hi! Ty ford
.plist are created by an application. Whenever I find that an application is acting strange: I restart, if that doesn't fix it I drag the .plist to my desk top and reopen the application and the application replaces it. I've never had a problem with disk utility which is an Apple application that is especially designed for the Mac. I would ignore the .plist warning unless all those applications fail to work properly. I have an old application that behaves erratically regularly and I restart to fix it; when restart doesn't work I remove the .plist and it runs OK again. One mistake I heard that some people don't turn off their Macs: What is the first thing that is suggested to fix the Mac when something doesn't work properly-Restart or Shut Down. I have very few problems with my old G4 because I shut it down when its not in use and OS 10.4.11 puts everything back in order at restart.
