I have a Mitsumi D357 disk drive which is only working single-sided (360K). Formatting a (known working) disk double sided results in a "disk error". Reading files of a DS floppy lists some of the files followed by "disk offline".

In other posts a read that a faulty head (upper) could cause this? From the outside the drive / heads look OK (if i compare it with a working D357).

PS: cleaning the heads I already tried but did not fix the issue.

Thanks in advance

Based on my experience with disk drive repairs I can only recommend you to replace the drive. Because the upper head is most likely dead.

Agreed, if the heads of the D357 came from Newtronics, most probably they suffer the "dead head" plague, no fix.

Thank you both for your replies. I will replace the drive and keep this one for spare-parts.
