500GB drive + SFS problem

[mechy]

Hello all,
   I am hoping someone can shed some light on this problem i am having:

I have installed a 500GB ide hd on my csppc scsi chain with a ACARD scsi->ide bridge. The problem is when i make a partition of say 400gb with sfs and format it,it gives me a DISK FULL error.I have tried all blocksizes from 512 to 32768. this seems to happen with anything over 100GB partition under sfs.I have tried using amigados format and sfsformat,with the same result. under 100GB or so i can format it no problem. If i use os3.9 ffs,i can partition and format a 400+GB partition with no problems but then i lose long filename support ;(((

Has anyone else ran into this problem or know a solution?

Mike

Stating the obvious here but why not just have 5 100g partitions..you will never fill one partition with Amiga software...

Problem might be the scsi->ide bridge.  Does SFS claim to support what you are trying to do?

Are you sure that you use QUICK option in format? It's the only way you should format big/sfs partitions.

And don't use random block sizes, you get data loss after a while if you do so.

--clip--
The current partition size limits of SFS are:
64 GB with 512 bytes/block
128 GB with 1024 bytes/block
256 GB with 2048 bytes/block
512 GB with 4096 bytes/block
1 TB with 8192 bytes/block
2 TB with 16384 and 32768 bytes/block
--clap--

And why to make too big partitions... they are hard to back up or fix if something goes wrong

@stefcep

I guess nobody can fill it with Windows _software_ either It's the general data files (music, videos) which fill up the space either on Amiga or on PC.

From changesSFS_NEW.txt:

- The limits mentioned in the 1.245 notes were wrong, sorry. The actual
  partition size limit of SFS 1.x is 128 GB, no matter which blocksize
  you are using. Changed the checks to the actual limits. You can
  continue to use too large partitions, but you may get "disk full"
  errors (instead of a trashed partition) even if there is still free
  space on the partition.

@ tjlazer: its not the bridge because the drive formats perfectly to a large 500gb partition under FFS with no problems.

@Pvc: yes,i used the quick format,as stated,it has a problem in both os3.9 format and the sfsformat proggy.

@mark: ah! Thanks for the info.This explains it,in real life practice it seems to take 124.7gb partition no problem,anything over that comes back with the "disk full" problem when i attempt to partition it.

the whole reason for the large partition was for all my mp3's,pdf's and mpeg movies.but i guess i will have to settle for small partitions.If anyone cares,SFS1.273 (i think) on aminet has the same problem.

Will there ever be anyhope of the sfs authors to fix this?

SFS1.xxx doesn't supports partition larger that 128(about) gigs.

Give to SFS2.xxx a try but ...

SfS 2.x was pulled from the page due to a bug iirc? i have a version in my archives.If i hadn't already broken the 500gb up and copied all my stuff to it,i would of tried it.I do prefer stability tho.
