MassFS
Plug in a USB drive and it appears with its name on the iconbar, eg USB_DISK with hard spaces (Alt-160) replacing spaces in the DOS disc name.
To save off a DOSDisc image of the disc, do
*Copy MassFS::USB_DISK adfs::HardDisc.$.temp.usbimage
To format the disc as FAT16 (DOS) format, use MkDOSDisc from the PC card sources (download the 3.06 source and extract MkDOSDisc from inside PCConfig/MKDOSdisc/. To format as 32MByte, do
*MkDOSDisc MassFS::USB_DISK.$ 32 -initdos
Don't try to format the disc larger than the size it actually is: it might be worth stepping down a megabyte or two from the published size, and beware that some devices are measured in sizes of million bytes (ie 32MB is 32,000,000 bytes rather than 32*1024*1024 bytes).
SWI MassFS_GetDriveCount (&56700)
- On exit:
- r0 = number of drives managed by MassFS
SWI MassFS_GetDriveInfo (&56701)
- On entry:
- r0 = drive number (from zero to number of drives managed by MassFS minus one)
- On exit:
- r0 = ?
- r1 -> drive name
- r1+20 -> connection?:drive_name:vendor_id:product_id (separated by colons, &3A)
- r2 = size in sectors (512 bytes each)
- r3 = flags?
