We should be OK.

Both HPFS and FAT32 have an IFS. It looks like equal support, but I
have eCS seeing HPFS without mounting, but not FAT32.

I have three FAT16, then an HPFS, then four FAT32, and then three HPFS
on a second drive. They all work.

All I have is one stick and a four bay mem reader. They work OK.

Today I replaced the MB in my storage box. It has four PATA HDDs, a CD,
a ZIP, and two floppies, all in the front panel. W4 works OK. eCS acts
like a flaky mouse driver. But I think they are both running AMOUSE.

All my working machines have two HDDs. I run FreeDOS, W2K and OS/2.
All OSs and normal data is on the first drive. That drive is currently
80G. The second drive I call "stuff"; things that don't have any
day-to-day use or maybe large graphic files. That drive is currently
200G. Those drives just happened to be the most cost effective size at
the time I acquired them.

Many IT pros huh? I always make all partitions accessible to every OS
if possible. The only time I ever had a problem was one time I let a
Win disk utility mess with an OS/2 boot partition.

It will run SCANDISK.

FAT32 has been native in DRDOS and FreeDOS for a couple years. I have a
500G drive with five 100G FAT32 partitions. FreeDOS can write to all
partitions.

Apps go looking for files. If you run the same app from two OSs, and
they see different drive letters, the app cannot find the files.

My only real primary is C: DOS. All other OSs are on a single extended.
Acronis boots them all clean. However, I have not been able to boot
eCS if there is a FAT32 partition in front of it.

I find it easier to build and maintain everything if I disable LVM. For
me, it is a solution looking for a problem. Jan was nice enough to give
us a button to clean it off the drive.
