In order to make the same set of emails accessible on both Windows XP Home and Fedora Core on my dual boot laptop, I have created a separate FAT32 partition which I use just for storing the Thunderbird mail files and directories. While working on Linux I mount this partition through an appropriate entry in /etc/fstab and have configured the Thunderbird profile in Linux in such a manner that it points to the files and directories on this mounted FAT32 filesystem for accessing mails for different accounts. I also make sure that I am using the same version of Thunderbird on Windows and Linux.
Things had been working perfectly fine except for some small hitches but recently after I compacted the mail folders and deleted trash while working on Linux, the whole partition got corrupted and a number of mails were lost. Though I was able to repair the FAT32 mail partition and recover most of the files, its created some doubts in my mind regarding this whole arrangement and robustness of FAT32 filesystem under Linux.
Has anyone tried something similar ? Its important for me to have the mails accessible in Windows as well as Linux but not at the cost of data corruption and loss. What all can be done to make this arrangement more stable and robust and prevent any data corruption ?
I would really appreciate some suggestions or pointers in this regard.
Thanks,
Manish

Your idea sounds quite good. I hadn't thought of that. I suppose you could use a thumb drive instead of a partition on a hard drive. Personally I simply set one of them to not remove the messages off the server. I realize that means retrieveing them twice, and the sent messages are not mirrored on the other system. But on the plus side it would give redundancy...

In order for the thumb drive to be accessible on both Linux and Windows, the thumb drive partition needs to be FAT32 and it could run into similar problems as the hard disk partition. Moreover the large mail volume makes it impossible to keep them on the server.

How about using an ext2 partition and this software.?

Do you have the option of leaving them on the server at all times and accessing them using IMAP4? If so you can also point a webmail client at the server when you have neither the home or laptop PC to hand ...

Not really. I have limited space per account and moreover the archived mails are now almost 1 GB. I just want to make this work smoothly.

I used to do this also, but have since just put them on my linux partition because 1. I rarely use windows on this machine anymore, 2. I hate FAT32, and 3. Thunderbird would have to rebuild summaries or something every time I opened a folder for the first time (including on startup). If I was to still share it, though, I would do what I'm now doing on my desktop: make the FAT32 partition into an ext2 partition, and get the driver for windows at http://www.fs-driver.org . Excellent, easy to use, minimal problems, and I don't think you'd have any of the issues of FAT32's suckiness. ;) You could also make it ext3, but either way Windows would use it as an ext2 (w/o journaling for filesystem stability). -Dan

Thanks, I didnt know about this driver. Will check it out. I hope it wont create a mess on the partition.

I had something similar once (for pics., not mail, though), and if the driver supports it you might want to think about mounting/mapping the ext3 into windows read-only, just to be safe :)

Ouch. This is one of the big problems with a traditional Unix mailbox: when the mailbox gets large, programs have to do large amounts of re-ordering and rewriting to delete e-mails, and there's a lot of scope for things to go wrong.
But I'm still surprised that the FAT32 filesystem was the problem. I can't recall an occasion when that gave any problems. Have you checked smartctl -l error /dev/hda (assuming that it's an IDE disk)? Have you checked memtest86? I *have* experienced problems with disk and memory...
One other thing -- the mailbox was well under 2GB large, wasn't it?
Have you considered a rsync arrangement to keep known-good copies of your mailboxes? This would involve more diskspace, but would give you a certain amount of backup.
(And please tell me you've re-examined your backup routines!)

Unrelated to mail, but I had a bad experience once with FAT32 partitions. I had some left over from dual-boot days, and filled them mainly with photos. I had a cpu-fan failure that took out the motherboard. When I rebuilt I found that the ext3 partitions were fine, but the FAT32 ones were completely hosed. I tried every recovery tool I could find, recovering some files, but losing every .jpg on there.
I've never trusted a vfat partition since.
I note that man pages regarding partitioning tell you to let windows format partitions to be used by windows, and linux to format partitions to be used by linux. I think that says it all.

You know, it would be a lot more logical not to trust CPU fans...
Modern CPUs are provided with fans for a reason. Some CPUs are better than others at halting the system when the fan fails -- it sounds like you experienced quite a bit of collateral damage.
In particular, you can't trust a CPU to work as designed in such cases, and any writes to disk are dodgy.
Actually, come to think of it, not trusting computers or *any* filesystems would also be a logical conclusion.
At least, not trusting them enough that you run regular backups.

The fact remains that I lost nothing from the ext3 partitions.

Actually, I think it's truer to say that some motherboards are better at halting the system when a fan fails. If it had been the only system in the room I might have saved it by manual intervention, but I mis-heard the source and hit the wrong shutdown button.

I'm sure you have met Murphy and his cousid Sod ;-) Almost everything was backed up, but the newest set of holiday photos wasn't.

I do not know if this qualifies as an option, but I use a second server with IMAP. All my mail goes there and I set thunderbird from either windows or linux to use that server as the mail source and to send everything through it.
One advantage is that it gets all my mail during the day and does the spam filtering without occupying my main machine. Maybe it's overkill, but then again, if Ihave a spare server around, why not use it?
