Hi guys, I'm not sure I'm posting in the right place, plz move the thread if it is not.

I was making an XP / 98SE dual boot, and the partition and its folders can be viewed correctly in DOS, XP, and safe mode in 98SE.
but when I view the content in a folder in Win98, for one folder with contents, it turns empty (no hidden files), another folder all its subfolder & file names are corrupted with unrecognized symbols.

It's a 60G HDD and the partition layout as follows:
Win98SE, 2G, primary + active, FAT32 (code 0B)
WinXP, 13G, primary, FAT32 LBA (code 0C)
Data, 40G, Extended (code 0F) with 1 logical, FAT32 LBA (code 0C) - problems occurred in this partition.

I've no idea what's going wrong. The folders are copied from USB disk in XP, I suspect its about different OS handling the same FAT32 partition in tiny different ways? but DOS and safe mode 98 all shows correctly.
The win98 is a fresh install, the previous installed 98 by me DO had the same problems right after installation but later turned OK, with no extra actions taken, just drivers installation, even no software installed. I even have the Ghost image for that working one, but I'm unable to find any difference between the 2. Ghost will backup the partition tables in MBR, so it could be a partition problem I guess?

Update: I checked the disk (partition) at the property dialog in XP and nothing happened. Then in 98se, I ran scandisk on the partition, it generated a huge amount of fragment files and the original folder became inaccessible. Results look the same for all OSes including DOS.
Tried recopy all files in win98 and there is a message about disk full. aborted and checked but the partition still had plenty of free space, meanwhile the XP partition is totally toasted as a unformatted partition. Looks like the copying process is affecting the XP partition which is prior to it. S**t I'm gonna ease all partitions except win98 and do the partition again using some tools in 98.

I used a usb ping to create my partitions, i don't let scandisk or defrag from Win 98 touch the drive, everythign get's fubared. Need to load it into my win 10 box, checkdisk it and make it work again. I have a 128GB volume for my Win 98 SE system.

I never encountered such situation myself. Tried PowerQuest Partition Manager in 98, created new partitions and found the only difference is:
the extended partition is Extended LBA (0F) same as before but the logical partition is FAT32 without LBA. XP can access the partition without problem.

I found a interesting thing that this time there're more valid folders and fewer corrupted. I guess its because this time I set XP partition smaller than last time, only 5 G (13G last time), and so the logical partition starts 8G ahead.
So it seems like the contents will be inaccessible when exceeded some address space.

Its been said DOS and 98 cannot handle HDD capacity larger than 128G cuz they don't support 48bit LBA natively. I never used that large HDD for 98/DOS, 60G is good enough for me.

Okay, if safe mode is working, I probably should use step-by-step mode to locate the driver causing the problem. Gonna do it in next week.

UPDATE: I stopped bothering with win98 because it is a laptop with 855M chipset. Instead, I instlalled WinME and everything works fine. the board has a SoundMax AC97 card so win98 won't get any good (especially DOS bootup) from it since the sound card doesn't support DOS.
