Hooking file access via a driver

Hi all,
I would like to write a driver in such a way that all file access to a media containing a ufs file system goes via my driver.. ie in the NT scenario its a filter driver... how do i do this in solaris 7.. can i write a driver which is just above the disk driver and catch all the i/o operations like read / write....
gurus any idea how to proceed about this... any help is really appreciated...
thanks
azad

This maybe possible to build a virtual driver which sits to map
into the actual solaris disk driver layer (sd driver). Start with bp_mapin()
manpage and DDW (Solaris Device Driver Writing) manual (http://docs.sun.com) and get more info on the bp_mapin() usage.
Hope this helps.

Sync fail - files accessed via app always older versions

Hi, I have a 2TB My Cloud device and various Android devices running the My Cloud App. I have the app set to auto-sync every 120mins however when accessed via the app my files are always older versions, often by a couple of months. The time stamp suggests sync has occured but when I open the file it is clearly an older version. No other error messages or obvious issues. Any ideas? ThanksStuart

Welcome to the WD Community,
If you access the drive directly from a pc, are you able to see the recent versions of the files?
Have you tried reinstalling the app?

File transfer via flash drive locks MacBook

Switched from a PC laptop recently to a MacBook. After the usual growing pains, still have a problem occasionally in transferring large files (folders of IT documentation and some are 300-500MB) via my Cruzer 1GB flash drive. Some transfer fine, while others lock up the machine before the transfer is complete. After recovering, can transfer the file again and it may work OK. Any ideas would be appreciated.

My friend, I believe you're right on. I may be speaking too soon but I tried my Verbatim flash drive and transferred three rather large files with no problems whatsoever. Hopefully the problem is solved. I was glad to see someone else was having the same problem. I was about to dump this MacBook. The transferring of files is important to my work and I haven't got time to fool with the problem. Thanks again.

What about 3rd party cloud storage file access via bridge?

First of all, lets all agree to get some training to the help chat lines. Inder was one I was chatting with and as I was typing another challenging question to the just down stupid answer I got being treated as an idiot, he or she cut me off, closed the chat and stated thank you for using Adobe chat support. I guess the stats on how fast you deal with an issue is far more important than proving a viable service Adobe. YES I AM F!@#$%G MAD.
So I found out that Bridge went out of their way in development to stop me from organizing and or just opening files from DropBox. All I wanted to do was conveniently open a JPG in RAW for some preliminary editing before bring the file into Photoshop CC. A feature that Adobe has been ranting and bragging about for a while. When I tried this GREAT feature in Bridge as it were, I could not even open the shortcut to the folders where I store my photos in the cloud DropBox. When I persisted, Bridge eventually crashed. I am sure that was some easy code to put in there to teach me a lesson for not buying Adobe cloud storage.
So, after had spending 1000s and 1000s of dollars on Adobe products over the last 20 + years, I get treated as an idiot, an undereducated consumer, no respect and have to adhere to timeline restraints to meet a undereducated / under-trained so called specialist stats she he she won't get reprimanded or loose their job.
So here is my knowledge to the issue at hand. I can not navigate Internet Based Cloud services without having to download them to my desktop first using Bridge CC. Thus rendering this app useless when most if not all project files are on the cloud. (Using the cloud makes so much sense in my case as a collaborator, project lead - manager, teacher in the arts of multimedia and a professional photographer).
Seems like there is no solution from Adobe, so my question to the forum is, what apps are you using to get around this issue. Adobe doesn't deserve my loyalty anymore and must EARN IT BACK! Third party solutions free or otherwise is welcomed.

MaxDB KNLDIAG file access denied

Hi,
I'm a DBA recently assigned to support MaxDB database (ver 7.6) used by
SAP Content Server in our windows 2003/32 bit environments.
Initially, our windows support group granted the DBA group access to
the files on E:\sapdb\data\wrk\CD1 where the KNLDIAG and other files
are allocated. We were able to view the KNLDIAG file when errors
occurred.
However, when the database instance is placed offine and back online,
we loose access to the KNLDIAG file, but not the other files on the
same directory/subdirectory.
Can you explain what is happening?
Is MaxDB doing something behind the scenes?
What can be done so that we don't loose access to this file?
I would appreciate any help you can provide.
Regards,
Bill

Yes, no problem!

Of course not - it's well documented
Unlike Oracle MaxDB does not use the same file all the time to write out the error messages.
Instead, with every restart the last file 'KLNDIAG' (and/or 'KNLMSG' in more recent versions) is renamed to 'KNLDIAG.OLD'. If there is already an 'KNLDIAG.OLD' this file is gone afterwards.
Then a new file is 'KNLDIAG' is created by the MaxDB Kernel with the default permission of the folder.
Usually these are dictated by the Windows account that runs the MaxDB-Service.
If you did not change this, this would be the "local systemaccount".
On my test system this results in default permissions that allow members of "Adminstrators", "Backup Operators", "System" and of course the "Owner/Creator" to access the file.
> What can be done so that we don't loose access to this file?
Simple: if you want to access it via OS tools, make sure that the user is a member of the "Administrators" or the "Backup Operators" group.
If you don't want to do that, just use the file access via the DBMGUI or DB Studio (or DBMCLI) to get access to the file.
regards,
Lars
p.s.
Maybe you didn't notice that by now - the KNLDIAG file is not simply written at the end of the file, but consists of a startup header part and a body which is cyclically overwritten.
For any newbies I cannot overstate the importance of reading the documentation [http://maxdb.sap.com] and/or get a training for it (SAP course ADM 515 really pays of here...)

CIFS UNC File access in Video Component

Does the FLV video player component support file access via CIFS (windows file share) using UNC path \\server\share\filename?
If Yes,
Is that considered local file access? or Network Access?
Do the Cross Domain Policy restrictions apply?
Thanks

Applets are not allowed to connect to other server
than the one they were loaded from. This is probably
the reason here.You mean that I can use the applet after uploading on my web-site and using "getDocumentBase()" only?
OK.
The applet works perfectly if I use that function, but I have another question.
If I want to use something like:
Img1=getImage(getDocumentBase(), "s01.jpg");
it works perfectly.
If I do the fillowing:
Img1=getImage(getDocumentBase(), "pic/s01.jpg");
it also works.
But is it possible to go a level up?
Like:
Img1=getImage(getDocumentBase(), "../pic/s01.jpg");
That is if an applet is in one folder and the pictures are in another, but to get to them I have to go a level up and then enter another folder.
Please help.
Thanks.

Open Siebel Offline Access via PDA (not blackberry)

Hi expert,
we are trying to access Siebel ondemand offline (the macro-enabled excel file) access via PDA phone (not blackberry).
However, there is a password embedded in the excel file that makes it impossible to open the file via PDA. Is there any way we can get the password? Or other ways to use Offline Access via PDA?
Thanks.
Sabrina

Hi Bob,
sorry to bother you again. We have been contacting Antenna but they do not have presence in Asia. We found another vendor in India, but they were not very responsive.
We need to use the PDA solution in greater China area, including Taiwan, China and Hong Kong. Do you know other vendor who may be interested?
Thank you very much. Sab

HT1661 My mid-2009 MacBook Pro has just died via a painful (for me) hard drive failure. I backed up a good percentage of files recently but not enough to keep me happy. I need to access the dead drive on the MBP via a 2008 iMac. Best options?

My mid-2009 MacBook Pro has just died via a painful (for me) hard drive failure. I backed up a good percentage of files recently but not enough to keep me happy. I need to access the dead drive on the MBP via a 2008 iMac. Best options?
I have ordered a 800 firewire to 800 firewire cable and am hoping to use the target mode option to copy files from the MBP.
Is this possible?
Hope so!
Any advice and or help would be greatly appreciated.
Many thanks,
Neil

Thanks Ogelthorpe.
Just bought an enclosure to try that also.
Hoping the MBP isn't really dead but just feigning death
Fingers crossed.

In server 2008 r2 i cant prevent access to extra drive letters(apart from a,b,c,d) via gpo

in server 2008 r2 i want to prevent access to extra drives like g,h,i,j drives via GPO i have been able to successfully hide these extra drives but not able to prevent access to restrict them i have hidden these extra drive letters via code pasting
with hidedrives.adm file on right clicking adminstrative templates in GPO and adding templates but i dont know the code for preventing access to drives. HELP me need this fast

Hi Manish,
Based on your description, we can try enabling the following policy:
User Configuration\Administrative Templates\Windows Components\Windows Explorer\
Prevent access to drives from My Computer
If we enable this policy, users cannot view the contents of the selected drives in My Computer and Windows Explorer. Also, they cannot use the
Run dialog box, the Map Network Drive dialog box, or the Dir command to view the directories on these drives.
However, this policy does not prevent users from using programs to access local and network drives. And, it does not prevent them from using the Disk Management snap-in to
view and change drive characteristics.
Regarding this policy, the following article can be referred to for more information.

I moved itunes file to external hard drive and want to move the file on my pc to recycle bin. When I move i get an error message that it cannot delete ituneshelper.dll access is denied. Can I move that file to the recycle bin?

I am trying to free up space on my pc and moving itunes files to external hard drive. I have followed instructions and believe I have file copied to new drive, but I am having trouble moving file to recycle bin as the instructions say. I am getting the following error message: cannot delete ituneshelper.dll:access denied, make sure disk is not full or write protected and file not in use. I know the file is not in use when trying to move. Any help would be most appreciated. I am on Windows XP.

Yes. And you should not have moved that folder. Put it back. To move your iTunes library move the folder from User's Music.

The circuit of my macbook is dead yet the hard drive is fine. I need to access a file from the hard drive, how can i do this? is there a cable i can connect to another mac that will let me transfer the file?

The circuit of my macbook is dead yet the hard drive is fine. I need to access a file from the hard drive, how can i do this? The mac turns on the screen freezes as bright blue. Is there a cable i can connect to another mac that will let me transfer the file?

There is another option if the Macbook will start up in Target Disk Mode.
Restart the computer while holding down the T key. If you see the firewire symbol moving around on the screen you can connect this one to another one in TDM. You will need a suitable cable to connect the two Macs.

How can I access files from a flash drive that were previously saved using a Windows computer? When I attempt to open the file on MacBook Pro, it is asking to "convert file to"; I also have Microsoft Word installed on the Mac as well.

How can I access files from a flash drive that were previously saved using a Windows computer? When I attempt to open the file on MacBook Pro, it is asking to "convert file to"; none of the options I choose work. I also have Microsoft Office (with Word) installed on the Mac as well.

Format the external drive as FAT32 or ExFAT. Both computers will then be able to read and write to it.

How do I access external hard drive connected to AirPort Extreme via iPad

Hello,
How do I access external hard drive connected to AirPort Extreme via iPad / windows laptop.
I donot have a Mac and I use windows laptop.

For your iPad, you will need an app, like FileBrowser, to access the external drive.
For your Windows laptop, you would access the drive like any other network share. The basic format is: \\<servername>\<sharename>, where, in this case, the servername is the base station name and the sharename is the name of the external drive.

After trying to change permissions on my computer so others on my network can access files, my external Hard Drive has a lock on it and I can't access files. I've tried repairing permissions, logging in under another Administrator account, using Terminal

After trying to change permissions on my computer so others on my network can grab files, my external Hard Drive has a lock on it and I can't access files. I've tried repairing permissions, logging in under another Administrator account, using Terminal to fix the problem, downloaded BatChmod but nothing works… Any other suggestions? I have an Imac running OS10.6.8.

There is suddenly a lock icon on my external backup drive!
