Since at least mechanically the head assembly seems to be one part and the drive reads/writes LS-120 disks fine I'm doubtful of a misalignment issue. Hey guys, thank you for the ideas! 😀 I'm trying to answer them one by one:Īs far as I can tell the drive has two heads, one on the upper side of the disk, one for the lower side - just like a regular 1.44M floppy drive - but possibly with multiple gaps (that's the term I found here, there's also a high res pic of the head assembly on that page. I never kept a LS-120 drive as the Zip drives were much better IMHO You could be facing the problems of the 360k vs 1.2mb floppy disk/drive read/write issue with track size issues, just a guess. Have you tried reading a floppy recently written off a known good 1.44Mb floppy drive ? One thing: the tracks on LS-120 disks are very small compared to standard floppy tracks. May that was already done and why it has issues with floppies. I remember this Warning: Do not clean them with a floppy disk cleaner disk or it can ruin the heads. The drive is configured as drive B:ĮDIT: Also tried the drive as only floppy/drive A: and running as master, slave and on cable select.Īgree ! From memory the heads on LS-120 are very small compared to floppy heads. I have tried various known good floppies and IDE cables, three different motherboards and Win98SE as well as WinXP Pro SP2.
Trying to format a 1.44MB floppy yields the same results: The drive operates normally for a moment then just stops working. Only shutting the PC down completely and powering it back up will make the drive eject the disk again. At this point the disk can not be ejected. The drive reads for a moment, maybe copies one or two files and then just stops and blinks. It reads and writes 120MB SuperDisks just fine but when trying to read from or write to regular 1.44MB floppies it causes the system to hang under Win98SE and Explorer to crash under WinXP. Yesterday I picked up a bunch of hardware containing among other things a 1998 LS-120 drive made by MATSUSHITA, model LKM-F734-1.
