Sorry for the rather long explanation, but I want to be as complete as possible.
In my current multi-boot system I use dmraid to control my raid 1 on a hpt372 controller card. However, the use of the linux version does not seem to go without problems.
All partitions are FAT32, and I can normally use them from windows. However on linux I put them as shared through samba and wrote to one partition (partition 1) and deleted from another (partition 2). Returning to windows, I had problems with these partitions, since one of the partitions contained my windows installation, I could not boot into windows anymore. Back on the machine in another windows, for both partitions to which I made modifications I had all my directories mentioned twice, for partition 1 this only concerned the directories I wrote to, but for partition 2 I had it for every directory on the partition. Running chkdsk on these partitions I had a large number of entries to which it said "cross-link solved by copying" and a large number of files it wanted to treat as directories and so on. So I'm guessing my "table of contents" on the disk is in a fairly bad state.
Anyway, before restoring everything I wanted to do a few tests, so I wrote to the disk from linux on the machine itself and then also from a windows machine through the samba share. by making 2 different directories and put a few files in them. Booting back into windows the directories were not there. So when back in linux I did an "ls" and they appeared, however if I did an "ls -al" then for those directories, I get: "Input/Output Error".
Following this I checked the dmesg for any io errors, but could not find any error messages. Hence I wanted to check the disks on a lower level of any errors and ran the diagnostic tools from the manufacturer in full test mode, this did also not reveale any errors or problems.
So I am a bit puzzled what the error is due to, and could not find any person with a similar problem. Is this due to the dmraid I'm using, or is it due to some personal settings: samba, fat partitions being mounted by particular user, or is it a combination of multiple of these ?
Hoping that anyone can shine some light on the possible causes of this problem I would like to thank you in advance.
Best regards,
Wim
