Zip disks
100MB, 250MB and 750MB cartridges. Magnetic media that has been sitting for two decades, and the reader hardware is now the harder part to find than the recovery skill.

Zip disks, Jaz cartridges and early external drives are now decades old, and what is on them has usually been forgotten rather than duplicated. That is precisely why these arrive — someone found a box and remembered what was in it.
Iomega was folded into LenovoEMC and wound down, so firmware, drivers and replacement enclosures no longer exist. What still turns up is a perfectly serviceable disk stranded behind a dead bridge board.
The phrase entered general use and the underlying failure is worth understanding.
Zip drives used a head that flew close to a flexible disk inside a cartridge. When a drive’s head became misaligned or damaged, it could physically damage the cartridge inserted into it — and a cartridge damaged that way would then damage the next drive it was put into.
That is what made it notorious. It was not simply a failure; it propagated. People worked through their entire cartridge collection trying to find one that worked, damaging each in turn, and the characteristic clicking as the head repeatedly attempted to find its position gave the fault its name.
The practical consequence today is unchanged: if a Zip cartridge clicks, do not put another one in that drive, and do not put that cartridge into another drive. Whatever you have left is worth more than the diagnosis.

1GB and 2GB rigid-disk cartridges — effectively removable hard drives, with the mechanical failure modes that implies.
Later USB and FireWire units containing conventional drives. Recovered as any external would be, and the bridge fails as often as the disk.
Iomega’s network storage, later sold under EMC and Lenovo ownership. Standard Linux storage underneath, recovered like any NAS.
The honest position on decades-old magnetic storage.
Unlike flash, which loses charge steadily when unpowered, magnetic media is genuinely durable — the magnetic domains holding your data are stable for a very long time in reasonable conditions. Twenty-year-old Zip disks frequently read perfectly.
What degrades is everything around the magnetism. Lubricant on the disk surface can break down, the flexible substrate can deform, adhesive in the cartridge can migrate, and humidity and heat accelerate all of it. A cartridge stored in a loft has had a harder life than one in a cupboard, and it shows.
So the answer to “is it too old” is usually no — but storage conditions matter more than age, and a cartridge that has already been through a failing drive is a different proposition from one that has sat untouched.
The propagating damage is the whole reason this brand is remembered. One suspect drive can work through an entire collection.
If you have several, send them together. Where one is damaged, others from the same set frequently hold overlapping content.
Working Zip and Jaz hardware is scarce now, and that is our problem rather than yours. Cards, cartridges and legacy media in Manchester are from £250 +VAT after a free 48-hour diagnostic.
Frequently, yes. Magnetic media is durable and twenty-year-old cartridges often read perfectly. Storage conditions matter more than age — a cartridge from a loft has had a harder life than one from a cupboard.
A Zip drive with a misaligned or damaged head could physically damage cartridges inserted into it, and a damaged cartridge would then damage the next drive. It propagated through collections, and the clicking as the head hunted for position named it.
Stop immediately and do not insert another cartridge, and do not put that cartridge into a different drive. The damage spreads in both directions, and whatever you have left is worth more than confirming the diagnosis.
No. Working Zip and Jaz hardware is scarce now and that is our problem rather than yours — send the cartridges and we will handle reading them.
The magnetism itself is remarkably stable. What degrades is everything around it — surface lubricant breaking down, substrate deformation, adhesive migration — all accelerated by heat and humidity.
From £250 plus VAT for cartridges and removable media, after a free 48-hour diagnostic. Send everything you have from the same set rather than a single cartridge.
