The PocketZip is a medium-capacity floppy disk storage system that was made by Iomega in 1999 that uses proprietary, small, very thin, 40 MB disks. Its relation to the original Zip drive and disk is the floppy medium and relatively much higher capacity than standard floppy disks. It was known as the "Clik!" drive until the click of death class action lawsuit regarding mass failures of Iomega's Zip drives. Thenceforth, it was renamed to PocketZip. A 100 MB Pocket Zip drive version had been in the works, was intended to be backwards compatible with the 40 MB disks, but ended up being vaporware and PocketZip itself would be discontinued as well.
PocketZip drive and media
The PocketZip drive was available originally as a laptop PC card (PCMCIA) slot drive where it could compete with contemporary PC card, MicroDrive, CompactFlash and SmartMedia readers. A dock was available to connect this drive to a desktop computer's parallel port. Later, a USB version of the drive was also offered. It was marketed as a backup and portable storage solution, similar to the original Zip drive, but which could be installed completely inside a laptop computer, as PC cards typically slide completely inside the laptop computer and thus do not increase its dimensions, which also precludes the need for a power supply or cables.
The PocketZip media is a small, flexible disk inside of a thin metal casing, similar to that found on the shutter of a standard floppy disk. The disks usually came in small format-specific plastic cases, and the drive was also shipped for a while with a small hard metal case which could house the drive and two disks. The disks could be bent easily if too much force was applied, thereby completely damaging them.
A similar device, Digital Capture Technology (DCT), with smaller disks and storage of 1.5 GB was rumored to be in the works in the early 2000s.
Use in consumer electronics
The format was also used in a small number of consumer electronics, including the Iomega HipZip Digital Audio Player, the Sensory Science Rave MP 2300, and the Agfa ePhoto CL30 Clik. The format saw use in other devices as well but proved to be a commercial failure. It suffered heavy competition from flash memory based memory cards. The PocketZip was electro-mechanical and, hence, was not as reliable as solid-state flash memory cards which have no moving parts; also, as the capacity and speed of flash memory storage increased and its costs decreased, the PocketZip lost viability as a portable storage solution.

Operating system support
According to the original documentation, Pocket Zip USB and PC Card work with Windows 95, Windows 98/98SE and Windows NT 4.0. Iomega provided USB mass storage support for Windows 95 with at least OSR2 (4.00.950B) for use with its Zip products. Under Windows NT 4, Pocket Zip PC Card only works with certain PC Card controllers (which ones are not named by Iomega). Pocket Zip USB also works with Mac OS 8.x, but the PC card version is specified as not working with Apple computers.
In practice, the USB drive is a standard mass storage device, so it will also work on any modern operating system which can use such devices, including Windows XP, Vista and 7, Mac OS X and Linux. The PC card drive, similarly, is a standard removable ATA device, so it also will typically function without any problems on modern operating systems including Windows XP. The problem on the latest operating systems is unavailability or incompatibility of the software used to operate the proprietary features of the drive, such as low-level formatting and the software write protection.
