If you ever have trouble reading disks on your MO drive, it may be that the drive lens needs cleaning. Or if the problem is specific to a certain disk, that disk may need cleaning. There are products available for cleaning the drive lens and MO disks. Fujitsu, IBM and Verbatim are three sources for these. Non-brand-name combined MO/MiniDisc disk cleaners are available very cheaply; less then 2 pounds.

There are many products available for storing 3½" floppy disks. MO disks come in individual hard plastic cases, though you could instead store them in a 3½" disk box.

For portable storage, anything which holds an even number of 3½" floppy disks on top of each other should hold 3½" MO disks nicely. For example, the aidata "DiskToGo/2" product (model: 3502-4) is excellent for storing a single 3½" MO disk. The Allsop "DiskFile 2" product is similar. These are probably sturdy enough for sending MO disks by mail, but you should use a padded envelope in any case. A box for holding ten 3½" floppy disks will hold five 3½" MO disks.

MO disks usually come with a two stick-on labels. If you run out of labels, there is no problem; standard 3½" floppy disk labels fit nicely.
