It was definitely while I viewed the folders in Ubuntu, I think they were on a FAT32 partition

669094 2008-05-15 03:06:00 I always heard that NTFS support in linux was unofficial, what with it having to be reverse engineered as microsoft didn't give out the documentation.

Not sure how it stands now but I'm pretty sure it works just as well in linux as it does in windows

669095 2008-05-15 06:21:00 The problem is not in the files themselves . They'll probably be OK, if you can access them .

It's the directories which are being clouted . The huge file sizes and the illegal characters are the clue to that . :D I used to see this in DOS systems .

It probably can't be two programmes writing different versions of the directory, because that would just cause missing files . Perhaps one programme is writing to another programme's buffers?

Bad memory is another possible cause, but Memtest says it OK .

I would not want to do anything causing disk operations while defragging a disk . I'd be inclined to not do anything while doing a backup, either . Unless there's proper file locking in the OS, it's very dangerous . A lot of commercial systems are backed up in the middle of the night, when noone's using the system .

Damnit, and here I am remembering reading some documentation that said the drive had to be NFTS to install Ubuntu...

Yes, It very well might be the directories that is clouted since the thing causing my troubles does not require a file to be open to destroy it . However, I have never missed a file or folder, or or got new once which I do not reckon .

I still use w2k SP4 but will update to XP in a not to distant future and I am not to familiar in how Microsoft is handling these things . But, what makes me worry is why I started to see this cinda problem now and not earlier even though I still use the same set of programs as before and I also had a much tougher schemes for backing up stuff than now, and some times i even backed up some part of my data in which I was not working, while working on other parts .

Do you think it would be related to FAT file systems only or could it be that NTFS could be affected by this behavior as well??

669098 2008-05-17 03:35:00 The appearance of the results would be much the same whatever the filesystem . A directory is just a file containing data in a fixed format . If "anything" is written over it, the system still "knows" it's a directory, and tries to use it as one .

I worked out how FAT worked when I needed to transfer files from PDP11 using RX50 floppies to IBM PCs . Writing IBM (DOS) floppies on the PDP11 (RT11) was surprisingly easy . Although MS didn't make information available, I found all I needed in a CP/M book . :cool:

But I found what corrupted directories looked like on PCs . :thumbs: The illegal characters, and huge file sizes were typical .

669099 2008-05-21 20:04:00 Okay,,, all this is fince, but why now... why does this start to happen to my system now... :illogical I cant figure it out and it makes me suspicious to my system since it is not reliable anymore. Maybe there is some rare corrupted os thingys.

Anyway it will not be forever since I am about to switch to win XP in the nearest future and I will do a complete re installation of the system then. Hopefully this will also get rid of the problem.

I am also switching to a even bigger HDD and I had plans of using the old caviar as an internal backup disk , but I am not sure if I dare do that anymore since I dont know if it was a sw fail, user fail (i.e. me!), motherboard and diskdriver fail, or a HDD fail which caused the troubles.

My bright future will show! :banana

Ubuntu likes to use the Ext3 filesystem by default - It would never say you should use NTFS . . .

Maybe you installed a bad program or a broken update to a program? Perhaps drivers also, have you checked those (especially chipset/storage drivers)

Run the latest version of memtest overnight just to make sure it's not your RAM

If the drive really is corrupting the data like that (which is unlikely) you should notice other things - like bad noises coming from the drive etc . . . and SMART should be throwing a fit by now

I push a button on that one, especially when it comes to the disk drivers . I used the drivers which came with the motherboard and updates of those .

I will run memtest to night (it was version 1,70, which came with ubuntu and which I used . I am not sure of how well this version supported i945GZ chipset, but I will download and use latest version (2 . 01) tonight)

Thanks
