[comp.sys.amiga.tech] Can FFS handle really large files?

r_carlso@hpfcdj.HP.COM (Richard_Carlson) (10/15/90)

   The other day, I had to transfer some rather large files from an
IBM PC to an Amiga 2000 (with "old" ROMs and 1.2 AmigaDOS); the
largest was around 4 MB.  Not having a bridgeboard or anything, I
connected the serial ports and used the old 1.0 "convert" & "read"
programs to place the files into one FFS partition of my hard disk.
No problems.

   That is, no problems until I turned off the Amiga and rebooted it
the next day.  Upon accessing that hard disk partition, I got a nice
little requester saying "not a DOS disk".  OK, I figured, maybe
something weird happened during all of that disk I/O; or maybe that
1.0 "read" utility has some sort of weird interaction with the FFS.
So I got out DiskSalv to copy the files I transferred over to another
partition of my hard disk.  Again, no problems *until* I rebooted
the Amiga, and discovered that my second partition is also no longer
a DOS disk.

   Are there any known problems with very large files on FFS?  If so,
just what have I done to my hard disk partitions; can I clean them up
with a little Sectorama'ing, or are they probably really trashed out?
If not, what else could explain these problems; I've had *no* other
problems with my hard disk in the year that I've owned it?  If I
upgrade to new ROMs and/or 2.0 AmigaDOS, should I be able to recover
those files?

   I feel like I should know the answer to this question, but I only
seem to recall hearing about large-file problems with the *OFS*.
Thanks for any suggestions.
