Summary	06747: einstein: Formatting on double-density drive fails!
Description	Notes: a) Old systems with XtalDOS versions less than 2.x only supports single-sided 40 track drives! b) New system 5 with XtalDOS 2.x supports single-sided and double-sided 40/80 track drives! The default set-up under XtalDOS 2.x is for drives 0 and 1 to be single-sided, and drives 2 and 3 to be double-sided (all 40-track)! (Note: This can be altered as is explained in the Systrem 5 manual, but is not needed for this test.) c) The System 80 also supports single-sided and double-sided 40/80 tracks drives! The default set-up is for drives 0 and 1 to be single-sided 40-tracks and drives 2 and 3 to be double-sided 80-tracks! (Note: This can be altered with "CONFIG" command.) So here is the list of all possible drive configurations that System 5 and System 80 supports: Single-Sided, 40-Track (188k) ==> The original 3" drive Double-Sided, 40-Track (386k) Single-Sided, 80-Track (386k) Double-Sided, 80-Track (768k) In the current MAME/MESS implementation, in the "Machine Configuration" internal menu it is possible to set between Single-Sided or Double-Sided drives! (all 40-track drives, I guess, so no posibility for 80-track drives)
Steps To Reproduce	- Start the einstein driver as "empty". - In the "Machine Configuration" internal menu set drives 0 and 1 to be single-sided and drives 2 and 3 to be double-sided. (Press F3 key to reset) - Mount the System 5 (or System 80) into drive 0 and press "LCtrl + LAlt" keys to boot. - In the internal menu "File manager" create new disc images: for drive 1 (new_40SS.mfm) and for drives 2 (new_40DD.mfm) as read-write images. - Type BACKUP command (if System 80 see notes below) and choose to format and follow the instructions. Notes if System 80: Run the CONFIG and set drives 0/1 to be single-sided 40-track and drives 2/3 to be double-sided 40-track, save the config! (Note: the disc must be in write-supported format) Type BACK80 and choose to format and follow the instructions. - First format the drive 1 that is set as single-sided ... formatting and verifying passes! - Now try to format the drive 2 that is set as double-sided ... after formatting it shows an error on verifying? - If you exit from the BACKUP program and type: "DIR 1:" it works fine, but type "DIR 2:" and it shows nothing! (so formatting the drive 2 as double-sided is currently not working)
Additional Information	Btw. In the current swlist there are several files with size="432111" and one with size="435183". HexEditor says that these disks are 40-track double-sided, but as have all sectors equal on both sides are probably baddump by wrongly using SAMDISK tool settings. (all can be converted to single-sided and will also work fine) Now, if mount a such disc into drive 1 set as single-sided and type "DIR 1:" it will show the content, but if you mount into drive 2 set as double-sided and type "DIR 2:" it will not show the content, even the disc is double-sided.

No.14394 Duke Developer Nov 1, 2017, 11:20	Default for the drives is now 3" single sided for the internal drives and 5.25" 80 tracks double sided for the external drives (matches System 80).
No.14395 demotester Tester Nov 1, 2017, 15:09	Thanks for fixing this! (also note: in current swlist xmaster == system5p)
