I've had years of experience with FAT32 formatted HDDs but limited experience of what I can expect from NTFS formatted HDDs. I have a system with 3 x Parallel IDE drives on it (30 GB to 10 GB each) and 2 x SIDE 300 GB NTFS drives. The boot drive is one of the parallel IDE drives. System is WINDOWS XPHome The system is used as an informal server. The two SIDE drives are largely mirrored by use of user controlled backup software. The majority of data is photo files. 1. It's been suggested that after a system crash NTFS drives may be reluctant to allow you to access them in a rebuilt system or if transferred to another system. Thoughts? 2. Data transfer rate to the NTFS drives across the network or between NTFS and FAT32 drives is abysmal. Typically well under 1 MB / second. Transfers between 2 x SIDE NTFS drives seems to be much faster. Network is standard 10/100 UTP and works much faster for FAT32 transfers. The Windows installation is somewhat wounded in other areas and probably needs a complete reinstall. it will probably get replaced with XP professional. Are the data transfer rate problems typical of mixed NTFS / FAT32 systems or does this seem atypical. All relevant (and some irrelevant) wisdom welcomed.
