Whats the biggest hard drive I can fit?
RISC OS 3.5 and earlier can only support drives up to 512MB. For maximum efficiency, it’s recommended that you format the drive to 499MB. RISC OS 3.6 to 3.7, on Risc PC or A7000 hardware can support up to 128GB drives. ADFSBuffers should be configured to 0. Due to an inefficient file allocation system (see Q3.15) RISC OS 3.6 & 3.7 is wasteful of disc space if you’re storing a large number of very small files. N.B. Some older interfaces may not support more than 20GB due to old style code which only addresses the first 20GB. RISC OS 4 and above can support up to 128GB drives. The Iyonix hardware will support drives of up to 256GB but UDMA is only supported on the first 128MB. Most modern drives over 40GB won’t work when connected to the RPC motherboard interface. Instead, it’s recommended you fit a third-party IDE interface capable of handling large drives i fyou want to use drives larger than 40GB.
