"In Case of Difficulty" Should you experience some difficulty accessing an MS-DOS disk, here are some ideas that may help narrow down the problem. First, make sure you have configured the drive you wish to use the MS-DOS disk on by using either the "MountMF" command or the "Attach" command. If you are using the "Attach" command, specify the correct device name of the drive you wish to use. The device names correspond to the device names given by Commodore (ie. DI0: is the MS-DOS device name whereas DF0: is the AmigaDOS device name). The easiest way check an MS-DOS disk is to run the "DiskChk" program included with CrossDOS to generate error numbers that can be used with the following chart. Problem/Solution Chart Problem Solution (or areas to check) ============================================================= "Not a DOS Disk" Make sure the disk is an MS-DOS standard Requester density formatted disk. The disk may be an AmigaDOS or MS-DOS high density formatted disk. "Disk Ejected Too Disk removed before all information Soon" Requester written to it. Replace disk and retry may recover without corruption. We recommend you wait at least 3 seconds from the last disk access before removing the disk. "FAT Table Corrupt" Important information on the disk is Requester sensed to be corrupt. Use a disk salvage program on your MS-DOS computer to try to recover data where possible. "Disk Full" Exceeded the capacity of the system disk. Requester using Remove unnecessary files from the disk or "Install_msdosFS" use "Attach" command. "Not an MS-DOS Device name selected does not refer to an disk" response MS-DOS configured device. Chose the from "MFormat" device name such as DI0: instead of DF0: "DF0:BAD" disk This is OK. The task that handles the icon device called DF0: cannot recognize a foreign disk format. Used "MountMF" "MountMF" only configures all the drives from WORKBENCH or as MS-DOS devices but does not load the boot file file system code to save memory. Your but no icon first access of the device in a program appears will load the file system and the icon should appear. Copied icon to Copy only files with NO file extension. MS-DOS disk using WORKBENCH icons already have an extension WORKBENCH but (.info). MS-DOS file names can only have cannot properly one extension. Also, avoid file names access icon later longer than 8 characters. Rename files if on same disk they are a problem. Changed the MS-DOS The 5 1/4" drive does not support the disk on the 5 1/4" "diskchange" signal. When you change drive and still disks, issue the CLI "DiskChange" command get the old di- or our "DiskChg" command on the drive rectory from the before your next access to the new disk. previous disk Copied file to Avoid using spaces in files names. The MS-DOS disk but MS-DOS computer ignores everything after cannot find it the space character. when reading the disk on my MS-DOS computer Error=-4 TDPatch12 or TDPatch13 needs to be applied. Error=21 Could not find any sectors on the specified track. Probably not MS-DOS standard density formatted. Error=22 Sector not aligned with index signal from disk. Usually not disastrous. Retry may recover. Error=23 Sector not found. Disk may be corrupt. Retry may recover. Error=24 Sector identification info corrupt. Retry may recover. Error=25 Sector data may be corrupt. Retry may recover. Error=38 Index signal from the drive not received. Amiga needs service to correct hardware problem. ============================================================== If you still have problems, you can call us at: (313) 459-7271 Mon-Fri 10:00 AM to 5:00 PM Eastern Standard Time Helpful Tips Here are some helpful tips to make using CrossDOS as simple as possible. - Avoid file names longer than 8 characters. - Avoid file extensions longer than 3 characters. - Avoid space in file names or file extensions. - When using WORKBENCH, avoid transferring files with file extensions. Rename them first if necessary. - Make sure the type of file you want to use between both the Amiga program and the MS-DOS program are compatible. Example: A Scribble! file is not readable by a WordPerfect wordprocessor. - Should you exhibit read or write errors with no specific pattern, we suggest you clean the floppy drive heads of both the Amiga and MS-DOS computers.
