The Jaz drive in some ways is not very special. It is just an adaptation of a normal SCSI interface hard drive, so right away, it can be viewed by Operating Systems as just a hard drive.
The Jaz drive was a removable hard disk storage system sold by the Iomega company from 1995 to 2002. Internal and external 1GB Iomega Jaz drives with media. Following the success of the Iomega Zip drive, which stored data on removable magnetic cartridges with 100MB nominal capacity, the company developed and released the Jaz drive. Iomega recommends using a power srrip to turn on both the computer and rhe Jaz drive at the same time. The Jaz drive must be turned on before the operating system begins to load. Insert the 'Install' diskette that came with your Jaz Traveller into the computer's floppy.
What makes the Jaz drive special is that the disks are removable from the drive mechanism, and therefore if you use specially written driver software, you can treat this 'hard drive' as a very large (1 Gigabyte) floppy drive, removing and inserting disks as you like.
Iomega, being a mass market driven company, has written software, or hired someone to write software, for the following operating systems for the purpose of being able to remove the disks without turning off the computer or shutting down the operating system. These systems are: DOS, MAC OS, OS/2, Windows 3.1, Windows 95 and WinNT using the following file systems: FAT, VFAT, FTFS, HPFS, and whatever Mac uses. Keep in mind that not all operating systems understand each other's file systems, even though they all recognize the disk drive. The Jaz is a snap to install in the Macintosh. For a UNIX-like Operating System, you must treat it as a permanent hard drive. However in UNIX, permanent hard drives may be 'mounted' and 'unmounted' without turning off the computer. The Superuser (root) may use the Jaz drive just like a large floppy drive, while normal users probably cannot.

Jaz drives may be used as FAT file systems on UNIX, or they may be used as whichever file systems is supported by your UNIX. This may require fdisk, disklabel and newfs. Backups to UNIX based Jaz drives may be performed by tar, dump, cpio, proprietary software or simple copying. Keep in mind that access is random, unlike tape.
Jaz drive is the successor of Zip drive. Jaz drive is a SCSI device, which is an external drive. Iomega introduced Jaz drives in 1995. Jaz drives have rigid platters. Jaz drives can backup data up to 2GB. It is similar to Removable Rigid Disk (RRD) drive. Jaz drive has self-terminating interface (SCSI-2). It houses the conventional hard disks. Jaz drives connect internally to the computer through SCSI or IDE and externally through parallel ports. An availability of an adapter called as Jaz Traveler helps in connecting the Jaz drive to the parallel port.
Jaz drives are portable and help in backing up files for the user. Jaz drive is recognized as a hard disk and hence any application can be run through the same. Storage capacity available are 1GB and 2GB. 1GB Jaz drive does not support 2GB Jaz disk but 2GB Jaz drive supports both 1GB and 2GB cartridge. Jaz drive requires SCSI controller because it uses SCSI interface. Jaz drives have automatic playback and backing up options. It has speed almost like any other hard drive (but not equal to or greater than). External Jaz drive requires 100-240V and 50-60Hz frequency. In the year 2002, Jaz drive was discontinued. REV drive is the successor of Jaz drive.
Jaz drive Models
Iomega Jaz Drive
Some of the models of Jaz drives are as follows:
- Iomega JAZ 2GB Ultra SCSI External Drive (PC/Mac) 31191
- Iomega 2GB SCSI External JAZ Drive Disk Storage System V2000s 30271700
- Iomega JAZ 2GB Internal Disk Drive VS2000si Jazz 50 Pin
- Iomega JAZ Drive – V1000s etc
Advantages
- Removable media
- Good performance
- Helps in upgrading hard disks
- Meets SCSI-2 specifications
- System can be run from Jaz disk
- Good transfer rate of 5.5Mbps
- Good seek time of 12ms
- Backward compatible
- Lets conversion to and from the wave file format
- Storage capacity is larger than Zip drive
- Anti-gyro mechanism (Iomega) to prevent vibrations
Disadvantages
Jaz drive have certain limitations, due to which it has been discontinued, some are mentioned as follows:
- Expensive in terms of buying and installation
- Very unreliable (dependability is less)
- Storage capacity is less
- Less secure
- Disk requirement is more for backing up large data
- Backing up process is time consuming
- Even the disks are expensive
- Jaz disks are very costly compared to DAT tapes
- Supports for short term storage
- Prone to ‘click of death’
- Prone to overheating (initial Jaz drives)
- Read-write damage results in corruption of data
- Dust particles enters trough the side case of the drive, which corrupts the surface of the disk

SCSI Data Recovery
Jaz drive uses SCSI interface and data loss may happen from Jaz drives. Loss of data from SCSI Jaz drive can be due to hot swapping, damaged boot record, In such situation Remo recovery application is the greatest asset available. Read on, to know more about the application.
