I have been using IDE zip drives for backup since they came out. A 100 meg model first, then upgraded to a 250 meg once they became available. I have never had a bit of trouble with either of the drives, the 250 that I mentioned above is still used daily.
The cartridges, unfortunately, have a finite life span. To date, I have had two die. Each gave a warning before going TU by becoming hard for the drive to read, followed by clicking noises from the drive while trying to access the cartridge, and then complete failure to read the cartridge after that. I am to understand this is often a result of dust damage to the media. On both occasions I has able to salvage the data by dumping it onto the HD before the cartridge died completely. Both of the cartridges that died on me had been in use for about 2 years.
I don't have a very complicated backup set...5 cartridges make it up.
- Shareware/freeware programs
- Drivers
- Folders and registry setting that I carry from one Windows installation to the next
- Arcade emulation ROMs
- Miscellaneous
Also, the update patches for games. The .ini files for how I have the controls set up, save-games, etc.
The reason I like the ZIP drive so much is because it requires no drivers to operate in Windows, and no third party software like a CDRW. A lot of people aren't fond of them but my setup has worked great for me.
It is too bad the Castlewood Orb drive turned out to be such a POS; that one had the potential to have been great if it were better engineered.
