![]() ![]() BASF 6106 (04/1980) / Norton Disk DoctorĪgain, all information is correct. The media descriptor is correct with FCh, indicating 180 KByte capacity. BASF 6106 (04/1980) / Norton Disk Information I remember that one of the latest DOS versions of Norton Disk Doctor was very slow (slower than Scandisk, while unbugged NDD was much faster than Scandisk). ![]() The DOS commands format recognizes under version 3.20 even without further parameters the correct capacity, namely 180 KByte. Best utility is Norton Disk Doctor and better get it from Norton Utilities 2001 (v.5.0) last one to include Doctor, Unformat, Unerase, Diskedit. Formatting with Norton Safe Format and DOS format works perfectly. The 6106 is properly recognized as drive A. I have connected the BASF 6106 to the MFM controller, entered no FDDs in the BIOS and. It runs like a Swiss clockwork, is very quiet and looks like new. I also have a similar drive from Siemens. I can't believe it, but the BASF 6106 is almost forty years old and it works perfectly. With these versions no information has been written into the BPB (BIOS Parameter Block). The format with 8 sectors per track is only required for the very old PC-DOS 1.0 and 1.1 versions. NORTON SF does this! The format with 8 sectors/track is the first DOS disk format with only 160 KByte and one-sided. When formatting (single sided, 8 sectors/track) with FORMAT or NORTON SF I noticed that FORMAT A: /8 does not write any information into the boot record. Formatting with FORMAT works fine: FORMAT A: /1 /8 or /1 /9. Today I have once again brought out the BASF 6106 and connected it to my IBM XT 5160 with PC-DOS 3.30. Currently I only test my old floppy disk drives with my IBM PC (5150) or XT (5160). 1 and 2 described here are no longer in use in this way. In conclusion, I can only say that the revival of a 38-year-old floppy disk drive (1980) has performed well. For a retro PC, the year 1988 fits better :-). In place of / N and / T one can only use / F: 180 does not work here either! BASF 6106 (04/1980) / Formatting BASF 6106 (04/1980) / DOS CHKDSKĭo not be surprised about the date. The command is actually: format b: / 1 / N: 9 / T: 40. There was always the message: Parameter not compatible. However, formatting with the DOS command format did not work. A subsequent surface scan did not detect any bad sectors. With the BASF 6106 I have been able to format normal 2D/DD (360 KByte) disks on one side (SS) with Norton Safe Format with 180 KByte as well as with 160 KByte. <- Back to Part 2: Pictures Testsystem no. ![]()
