What I found is that TNC/PLC partition are relly small, 64 MB and 128 MB, the SYS has 1.7 GB, but the files inside of SYS partition are around 150 MB, and linux detected then as vfat file system.
I've got two used industrial 2GB CF (SLC) as the datasheet say that they has ECC, it is true that disk hdd usually give errors before saying goodbye, but the modern industrial CF come with wear levering, safe power down and so on, and I think the possibility of CF card controller die are just the same as the SATA hdd controller, some observation is that, lots of machine owner has no hdd image backup regulary, I could not only back up them regulary but burn those images in DVD, on google drive, losing them mean big trouble, and haveing it backed-up, might takes minutes to restore them into a new medium.
I might also be possible to get hold some bran new old stock IDE/SATA HDD, I might everntually get them all as they are around 5 usd each, having them, tested all and compare. What I don't like the SATA is that PATA -> SATA needed to use converter, and while CF standard are compatible to IDE, the SATA need a converter which, also come with firmware that might, or might not work well with the eprom firmware...
I am not sure if the hdd HAS to be formated in FAT16 (or VFAT to support long name? does 426/430 reads/uses long name at all?) or FAT32, but only if the controller eprom firmware support FAT32, also, the files inside the SYS partition are exactly the same the one that come with diskettes that are still available at heidenhain web site? or each machine manufacturer, also has their own version of SYS files?
After fsck.fat on linux, I found some dirty bits, short name error on the old hdd, I am going to keep the old hdd, and build a new hdd with the necesary files, well organized and partitioned...
Thanks for advices!!
