More HD Trouble ;-(

[PMC]

I had similar problems with SFS, so much so that I went back to the FFS bundled with OS3.9....

I had a similar problem whereby the Guru struck when my A1200 was accessing an SFS formatted partition.  The system would then throw a Guru again upon reboot, so the only way I could get the OS to load was to disable the offending partition in the boot menu, load WB and then repartition using HDToolBox.

Obviously I made sure that SFS was installed as per the instructions, and I made sure that I reformatted the drive after installing the file system but the problem persistantly reoccurred.

SFS seems to "dislike" certain hard drives as my old 420MB Western Digital drive - formatted under SFS seems to survive unscathed every time.

Maybe SFS gets snotty with larger capacity drives?

If it's any help, my Fujitsu 4.3GB drive suffered the symptoms I described with SFS, as did my 13GB Seagate.  

Checksum errors are a b*st*rd and I know how you feel with them!  However, FFS seems to be a lot more robust under OS3.9 than it did way back when.

I bought biggers drives than I acutally needed and mirrored each of my three partitions so that if one dies then I can restore the data via my floppy disk copy of Directory Opus in the event of losing my boot partition.  If it's any help I'd urge you not to use the "Quick Format" option when setting up new drives as this always leads to trouble.
