- I have a problem with my Sony MPF120-K0 3.5" diskette drive. It reads,
- writes, and formats 1.44MB (HD) diskettes without a hitch. It will also read
- *and write* 720KB (DD) diskettes with perfect ease. However, it will not
- *format* a 720KB diskette.
-
- The media change sense mechanism works fine. The density sense mechanism
- works fine. CMOS setup knows it's a 1.44 MB drive. Using /n: and /t: on the
- format command does no better than using /f:.
-
- If I format a 720KB diskette on my other 'puter, and then write it on the
- Sony, it's readable in every 3.5" drive I can lay my hands on. Every program
- save one thinks the world is rosy at 720KB -- FORMAT is the only exception.
-
- Symptom: invalid media, track 0 bad.
-
- I don't want to tell setup that it's a 720KB drive (because I use HD's 95% of
- the time). Similarly, I don't want to use drivparm or some such to claim
- the drive is not HD capable.
-
- I've found other people with the identical problem, but they've only shared
- sympathy, not solutions. Any help from netland? Thanks in advance.
