Lawrie) NNTP-Posting-Host: karazm.math.uh.edu Keywords: hardware, storage, floptical, SCSI, commercial Originator: barrett@karazm.math.uh.edu PRODUCT NAME Insite Floptical Drive I325VM BRIEF DESCRIPTION This is a 3.5 inch SCSI floppy drive which uses a combination of magnetic recording and laser tracking to store 21 MB on a floppy disk. It is a cheap alternative to optical drives. AUTHOR/COMPANY INFORMATION Name: Insite Peripherals Address: (Apparently they have moved.) USA Telephone: (408) 441-0660 FAX: (408) 441-1211 Name: MELCO Sales (NZ) Ltd. Address: 1 Parliament St, Lower Hutt, New Zealand Telephone: +64 (4) 569-7350 FAX: +64 (4) 569-3623 LIST PRICE $1100.00(NZ) is the approximate price for a Floptical kit. $825.00(NZ) is what I paid for a bare drive. $42.75(NZ) per 21 meg disk is the best I have found. All prices are in New Zealand dollars and include GST. Estimated prices in US dollars are half those shown above. SPECIAL HARDWARE AND SOFTWARE REQUIREMENTS HARDWARE Amiga SCSI controller. Large to small power plug adaptor. Optional: 3 1/2 mounting kit. SOFTWARE Insite drive unlock utility.(Available on aminet) Hard drive formating software. Workbench 1.3 minimum. (1.3 and 2.1 tested) MACHINE USED FOR TESTING Amiga 2000, 1MB Chip RAM, 2MB Fast RAM. ECS Agnus chip. OCS Denise chip. Commodore 2091 SCSI controller. Xetec FastTrack SCSI controller. AmigaDOS 1.3 / 2.1 INSTALLATION The Floptical drive will install in any 3 1/2 inch bay, but its faceplate is standard PC size. Installation is the same as a hard drive with the following exceptions: 1. The drive is protected by a thin tin cover, so some care is necessary. 2. The power plug is smaller than standard, and an adaptor is required. 3. As it uses floppy disks, there has to be external access to the front panel. 4. Insert the "insite" command early in the startup-sequence, but after "Binddrivers" and any other hard drive initialising software. As I received a bare drive, the SCSI address jumpering was a hit-and-miss affair. I settled on address 4 after some experimentation. REVIEW The first noticeable thing when booting with a Floptical is the time it takes for the drive to check a disk. It goes "clunk-clonk" and whirs a bit, reminiscent of a sick floppy drive. Both controllers take a bit of time to notice the drive when booting as it doesn't respond for about 10-15 seconds. This may cause problems with other controllers. Before you can do ANY writing to the drive, a utility is needed to send a "write sense enable" to the drive. Even low-level formatting cannot be done without this utility. There are two available on Aminet, the best being "insite" (filename: insite.lha). There is another called "scsi", and they both do the job. The command should be inserted in your startup-sequence AFTER Binddrivers and any other controller enabling commands. (For example, "Touchall" for Xetec controllers.) HDTools has no problem with the floptical AFTER the "insite" utility is run. Low-level formatting takes about 20 minutes, and AmigaDOS format is about the same, accompanied by a bit of clunking. In the end, the disk has 19 Meg of usable space. The disk acts just like a hard drive, with the exception of the write protect tab. This is the same as a floppy (on the opposite corner of the disk) and can be used to protect the disk from ALL writing. Write protected flopticals can be booted from on a virus-infected system or if something is trashing partitions (e.g., possibly some of the bugs in certain UNIX versions). Under AmigaDOS 1.3, the DiskChange command must be run several times when changing a disk. This isn't necessary for AmigaDOS 2.0 and higher because the computer polls the drive every 5 seconds: similar to the floppy interface, but without the annoying click. The disk icon disappears and reappears in an orderly fashion. If there is no disk in the drive when booting AmigaDOS 1.3, there will be a long delay until the controller times-out waiting for a response from the floptical drive. This is very obvious with the 2091 SCSI controller. Disk changes sometimes require a reboot to take effect. If the new disk has exactly the same partitioning as the old one, then disks can be changed without rebooting. Of course, this is not a problem if all your disks have only one partition. MessyDOS and CrossDOS can be used to read 1.44 MB PC disks. This requires a Mountlist entry and the appropriate software. It can be done. I have not been able to format PC disks using a floptical though. DOCUMENTATION I received a bare drive with NO documentation. There are kits available with all of this, which takes the guess-work out of the address jumpering. It's a SCSI device, so it shouldn't NEED much documentation. LIKES AND DISLIKES LIKES 1. The ability to store a reasonable amount of data with random access is what makes this product for me. I have 40 Meg of archive files stored away and duplicated on 4 disks. 2. Workbench fits on ONE disk. In fact several versions fit on one disk. 3. Another aspect is disaster recovery. All my important partitions are stored on a disk which I can boot from if the hard drive is killed. The hard drive can be reformatted/partitioned (or replaced) and all the data transferred back. 4. This could also be handy for UNIX users who could have a cut down system on 1 disk. Rogue software can't blow away a write protected floptical disk! DISLIKES 1. Initially the noise made by the drive was not to my liking. I'm used to it now. 2. The price of the disks! Initially I was charged $80 (NZ) each. Since then I have found a source for 3M Floptical disks at the price mentioned in the LIST PRICE section, above. DESIRED IMPROVEMENTS 1. Better Amiga support. 2. BIGGER disks. 3. A standard for the jumpers included in SCSI specifications, as this would make ANY drive simple to install. BUGS The drive requires a utility to enable writing. See above. VENDOR SUPPORT For me this was MELCO Sales (Mitsubishi ELectric COmpany). They were very helpful and replaced the whole drive when I told them that it wouldn't write. Later on they replaced a disk after I had messed it up so bad that NO controller could make sense of it. (The disk later formatted OK on one of MELCO's PC's.) Their technicians know a lot about the drives and are able to repair them. They will clean the drives too, as this can not be done buy the user. WARNING!!! DO NOT CLEAN THE DRIVE WITH A CLEANING DISK. The drive will require less cleaning (and expense) if ONLY floptical disks are used. WARRANTY 12 months. This will probably vary. CONCLUSIONS Apart from the fact that nobody from Commodore/MELCO/Insite was able to give specific help for an Amiga setup, I really like this product. The drive has performed flawlessly since I have been using it. To date I have had NO faulty blocks on any disks, including those with games on them. Games disks have received a reasonable thrashing for over a year! The physical write protection can be used in the case of viruses and experimental software to keep a reference disk free from interference. This reference disk can even booted from while still write-protected. The Floptical beats a tape for access and convenience, but storage is now small in comparison to other media (CD-ROM, DAT tape, and large hard drives).
