3.5 720K floppy disk

I have a Sony MPF420-2 floppy drive in a tool in our clean room (fab). The floppy has gone bad and i need to replace it. I can not find the mpf420-2 so i will need to find something compatible and set jumpers to match, except i can't find any documentation to show me what the jumpers are. Do you know where i can find this information?

SOURCE: REPAIR FLOPPY DRIVE

There are a few different applications that can aid you in doing this. Here is one. http://www.accurite.com/AAD.html Most often than not, the heads will not be realigned properly with such software, and the cost of purchasing the mechanical tools to do it manually and the time and energy it takes outweigh the cost of just buying a new drive. If you are having read/write problems, and an inexpensive head cleaner (http://pc-extras.com/prods/cl35ck.html) does not solve the problem, I would recommend replacement.

SOURCE: what is the jumper setting to make this a slave

How do you know that the HDD has a boot-sector virus? Can you tell us which specific boot-sector virus you're trying to remove? This is the direct link to the .PDF file with the jumper setting information you need: http://www.hitachigst.com/tech/techlib.nsf/techdocs/78090BF330EAFDA687256C4E0077DA0A/$file/T80gn_ig.pdf As you'll see, you need to move the jumper to the A2 position in order to set the drive as Slave, BUT, keep in mind that in order to use the drive through a USB enclosure, you will probably have to set the drive as Master, not Slave. Changing the jumper to the Slave position will DISABLE the onboard IDE controller, which could prevent the system from finding the drive through the USB port (which is what you've already described)... Which program are you scanning the drive with? Are you using an anti-virus program, ScanDisk, or something else? Please provide more details; removing a boot-sector virus can be difficult, so the more information you provide, the better the chance that we can help you resolve this...

The disk drive on my Yamaha Clavinova CVP-105 acts like it has a disk in it when it doesn't and won't always play pre-formated disks like it used to. Is the drive dieing? Where can I go to get it fixed? ...


Often these drives are continuosly selected by the controller and rotate even without a disk.

These USUALLY use the old 720K disks which are almost impossible to find. The common 3.5 1.44Mb floppies often will not work in these units.

You can SOMETIMES use the 1.44Mb disks by covering the second corner hole AND degaussing the disk with a tape eraser and then reformating the disk in the Clavinova.

The pre-formatted 1.44Mb disks without degaussing SOMETIMES leaves artifacts between the tracks used by the 720K disks that causes problems.

I have a technics sx ex35 organ with a broken floppy diskdrive. Where can I purchase a new drive and how much will it cost me?


It is near impossible to get parts for some of the Technics things... Find a source dealling in scrap computer recycling... take your drive there and see if you can find some that will fit connection wise and mechanically and just try them...

IF your floppy is one of the old 720K drives, those are almost non-existent... You can tell if you use floppies disk that have two holes at the two corners instead of a single one those will use the 1.4Mb conventional rather than those 720K ones...

SOMETIMES you may have to jumper configuration pins to work with these synths...

Not recognising any blank medis. Or if recognises, it tries preparing and then fails with 'Invalid disk'


For a barcode scanner?
The only ones I've seen with disks use floppies, so try using a cleaning disk in the drive, if that doesn't work, you may need to replace the floppy drive.

It's also possible you have 1.44MB floppies and the scanner only recognises 720K, but the drive itself sees the 1.44MB.

Simple fix for that is to use string scotch tape or a strip of packing tape to cover the hole ACROSS from the write protect hole (write protect hole usuaullyhas a slider in it, otherwise they are the same size hole)

BIOS SEES DD FLOPPY SYS (DOS ALSO) NOT


Most floppy disks that you will still be able to find are 1.44MB DSDD disks, which a 720k drive will not be able to read. Check the capacity rating of the disks. Also the 720k drive has got to be at least 20+ years old, and the read/write heads may simply not work anymore. 1.44MB flopyy drives are literally a dime a dozen, you can probably pick one up at your local thrift store or electronics recycler for less than the bus fare it took to get there.

FD-235HF-7529


This drive supports Ready signal or Disk Change signal on pin 34 (RY34 or DC34), has a large number of jumpers for various settings, thus (unlike the standard 235HF drive which works in PCs only) this drive can used to replace a 720k drive on older computers such as Amstrad CPC/PCW or Commodore AMIGA.

Epson smd349 floppy


Hi Elia, Could be a couple of things: -Your drive may only be a 720K drive. They will format 1.44 MB disks but only with a 720K format. The test is inserting a HD disk and try formatting it as HD. -The disk could be mislabeled, HD disks have two holes on end opposite the slide, one to write protect the disk and the other to signal to 720/1.44 capable drives this is a HD disk. -The HD disk could be formatted as a 720K disk even though it is an HD disk, reformat as HD. -The new, used drive could be damaged. -The drive could be configured as a 720K by the computers BIOS. You?ll have to enter the BIOS setup find the config for the A drive and set to 1.44MB. Let us know what happens and please don?t forget to rate the posting.
