> Is there a problem with Mac OS 8,6 handling data?? None that I know of. I used it for years without any problem of that kind. The only HD limitation with Macs of that era (but non specific to 8.6) is the 128 GB limit even on bigger HDs (limit removed with newest G4 Quicksilver and up). > How 6GB of data consume more than 15BG on my HD?? The only thing I can think of, is if you copy a *large* amount of *tiny* files. IIRC, since HD space is allocated in chunks called cluster (and they usually are as big as 512 to 4096 bytes), if you store a text file with just the word "Hello" in it, the file will be 5 bytes (characters) long, but it will occupy a whole cluster nevertheless (thus 4KByte on newer HD), "wasting" 4091 bytes. When you have lots of small files, this "wasted" space can be significant; and it grows on newer HDs that have bigger clusters. Hence, if you copy lots of small files from an old HD (with small clusters) to a new HD (with bigger clusters), the actual data copied will be the same, but the space occupied by the files on the new HD will be much bigger. E.g.: you have 1,000,000 files, each long 100 bytes. The actual data is 100 MB (1M x 100B), but: - On a HD with 512 bytes clusters, those files would occupy 512 MB (1M x 512B). - On a HD with 4K (4096 bytes) clusters, the same files would occupy 4 GB (1M x 4KB = 1,000,000 x 4,096). If you copy those files from the old to the new HD, you'll start with 512 MB and you'll end with 4 GB occupied... and you might wonder why your data has "grown" eight fold! :-o This on a theoretical level. Actually, I don't think this is likely what happened to you, but is the only explanation I can think of (short of a HD malfunction). -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
