[ REMOVABLE MEDIA // MODEL-SPECIFIC RECORD ]
Iomega Bernoulli 8-inch 20 MB Cartridge
Original Iomega Bernoulli Box, 8-inch media generation (introduced 1982). 20 MB nominal removable-disk capacity, the top capacity documented for the original 8-inch Bernoulli family. The flexible disk is enclosed in a rigid cartridge.
IDENTIFICATION: Verify the exact capacity, physical format, and generation printed on the medium. A cartridge has no host interface of its own; drive interface and system support must be checked against the exact reader model.
Format, capacity and compatibility
| Product / media model | Iomega Bernoulli 8-inch 20 MB Cartridge |
|---|---|
| Generation / format | Original Iomega Bernoulli Box, 8-inch media generation (introduced 1982). |
| Capacity and medium | 20 MB nominal removable-disk capacity, the top capacity documented for the original 8-inch Bernoulli family. The flexible disk is enclosed in a rigid cartridge. |
| Media and drive interface | Cartridge has no electrical interface. The original external drive used a controller/host connection specific to the drive configuration; verify the controller, cable, and host support independently. |
| Compatibility | Use with an original-generation Bernoulli Box drive explicitly supporting 20 MB media. No host connector is present on the cartridge; controller/interface compatibility is determined by the drive. Not compatible by form factor with 5.25-inch Box II cartridges. |
| Version and model caveat | This 20 MB 8-inch cartridge is not the later Bernoulli Box II 20 MB medium: the latter is 5.25-inch and belongs to another physical drive generation. |
Handling and preservation
Keep the cartridge in its protective case, away from dust, moisture, heat, strong magnetic fields, and physical shock. Do not open a sealed cartridge or force it into a drive. For preservation, image read-only with a known-compatible mechanism, retain the source media, record the drive/interface used, and verify copied data with checksums.
- Photograph the label and shell before use; preserve packaging, write-protect state, and acquisition notes.
- Keep at least two independent verified copies of important data. A legacy removable cartridge by itself is not an archival strategy.
Model and generation notes
This 20 MB 8-inch cartridge is not the later Bernoulli Box II 20 MB medium: the latter is 5.25-inch and belongs to another physical drive generation.
Storage capacity names and drive interface names describe different things: confirm the cartridge format/generation first, then check the exact reader model, host connector, controller, operating-system driver, and filesystem separately.
