Unfortunately SFS (AmigaOS version) has some bugs that cause self destruction sometimes. Ok, not self destruction but it corrupts itself and there are no repair tools. Only solution is taking a backup and reformatting partition and then copy back.
And of course remember 127GB size limit (in case you are using larger HDs).
Is it? Does it even have any effect?
Well funny with the load of machines i use, some run 24/7 i've not lost a single partition.. samsung ssd,sandisk cfs and regular drives, in 20 years of using it i have never had a partition loss caused by it, I have also sold many amigas pre-setup with it and talked at least a few hundred people thru setup and use in these years. I use drives from 50mb to 1TB,and yea i know of the 128gb partitions which is not a big deal.
SFSsalv works for sfs/00 partitions,not that i have ever used it.
I am not trying to sell anyone on it, i just think i have put it to the test. Either i am incredibly lucky or the claims are unfounded.
I dont want to hijack the thread though.
