 <P STYLE="margin-top:0;margin-bottom:0;"><FONT FACE="MS Sans Serif" SIZE="2">One caution: if you format a disk for ProDOS, and then format it with your camera, you may find that it still appears to have some ProDOS files on it.&nbsp; (CiderPress should identify it as an MS-DOS "FAT" filesystem, but if the camera uses a non-standard boot block it may not be detected correctly.)&nbsp; Some files may appear to be damaged.&nbsp; This is because the camera's format routine didn't zero out all of the blocks, so some of the ProDOS directory structure is still present.&nbsp; Attempting to read or write files to the volume as if it were a ProDOS disk is not recommended.&nbsp; The safe way to switch between Apple II and Windows formatting is to use the image-copy tool to overwrite the entire CF card.&nbsp; Be aware that formatting with a camera can reduce the number of blocks available on the drive, which will make copying images onto it impossible: the image copier only works if the destination volume is at least as large as the source volume.</FONT></P>

Andy McFadden	2cb5bf0dcc	Fix file viewer layout If scaling > 100% is enabled on the primary display, the controls in the dialog window get bigger. The file viewer uses hard-coded values for the initial and minimum window size, which causes the expanded controls to draw on top of each other. (Issue #53.)

Andy McFadden	d39c61255c	Work around ProDOS sparse block issue It appears that some programs, notably Copy ][+ and the GS/OS FST, expect that the first block of a sparse file will always be allocated, even if it's just 512 zeroes. I've only seen this fail in cases where the first entry in the master index block of a "tree" file is zero, because the first 128KB are sparse, but rumor has it that the issue can affect "sapling" files as well. This changes CiderPress to work the way ProDOS does: always allocate a block to hold the first 512 bytes of the file. The only exception to this is a file that is nothing but zeroes (perhaps populated by creating a file and setting its EOF to something large), which can be stored as a seedling. (for issues #15 and #49)	2021-07-23 18:52:23 -07:00
