I have an drive on my A4000 that is formatted with NT File System. I created a mountlist for it and I'm using the ntfs driver for AmigaOS on aminet. It works in that I am able to mount the drive and see all of the files. The problem is when I open certain directories I get the following error...like maybe 100 times or more. Again and again and again... I click "ok", "Ok", "Ok".... Some folders open up without any problem, but others will launch this damn error loop.. The only escape is to reboot, or click ok like 200 times! Its driving me nuts. :crazy:
The error is:
"NTFS Error"
"Found compressed, encrypted, or sparse attribute that is not (yet) supported. Attribute Record 1844416, Type 128, Flags 1, Offset 208"

Is there any consistency in the files which produce this error? IOW, can you identify that the files which fail have a common attribute which working files don't? Maybe particular permissions?

Have you enabled file compression on the drive? Right click on the drive from within a Windows environment and see if the compression option is checked off. It may be that some of these files/folders are compressed and mess up on the Amiga. The only other thing I can think of is that the driver that you are using just doesn't support some of the new NTFS features that a Windows env might be using.
My $0.02 worth...

Not really. I see that the "Record xxxx" and "Offset xxx" changes each time I click Ok, but I can't see any commonality between which folders trigger the error and which ones don't. For example, the root triggers it maybe 50 times. But "Windows" and "Sys32" do not trigger it. "My Documents" triggers it over 100 times. But "Documents and Settings" does not. "My Pictures" doesn't. "My Videos" does.. :/ I'm flummoxed..

I thought compression might be the problem, too. But I checked. Compression is disabled.

That is weird. It doesn't even seem to be related to the depth of the folder in the filesystem. Have you tried Googling NTFS attribute 128 to see if you can find out what the attribute is (assuming it's always 128 in the errors)

Maybe it is compression after all? There might be data on this drive that was compressed years ago on a different drive and different PC, but which was copied over from backup media. So even though compression isn't enabled on the current drive, there may be data on it which at one time resided on drive that was using compression. Does that make any sense?
-
Isn't there an option in XP to push the attributes down to all subfolders and files? That should remove compression from any files and folders on the disk.

Yep, yer right. I'll bet thats it. Thanks dude

Don't thank me, thank RRunner - it was his idea to check compression ;-)

Thanks dudes. :)

You can disable compression by removing the compression flag on the root directory and applying this to all child objects (this may take some time).
Just another thing: NTFS support multiple streams,this functionality is often used by antivirus I'm pretty sure that streams aren't supported too.
