CD-whatever drives double as a CD-Rom reader as well.. The CD whatever drives are slow compared to CDROM drives. They can double but it is not my first choice. You can get a nice CDROM for less than $100. As someone mentioned once (maybe it was you?) the linear structure of tape leads one to wish for a better way. I think it was someone else. However I agree. I like the random access nature of discs. I'm trying in my reading to understand the difference between cd-r and cd-rw. Is cd-rw rewritable and cd-r permanent or is there moe to it than that? That's the basic difference. There are other considerations. Most CDROM drives (except some of the most recent drives) will not read CD RW media. More drives will read CDR media. Many older drives (pre CDR era) will not read CDR media. Both require specialized software to record. Both drives will act as readers without specialized software. CD RW is still a bit too new IMO. Iomega, Syquest and others make removable GB+ discs. I opted (at work) for HP 2.6 GB removable Magneto Optical drives (MO drives). The Iomega and Syquest drives are proprietary drives. I chose the HP drives as they are not proprietary... but are a lot more expensive ($2000 +/-). I had bad luck with IBM and Pinnacle Micro MO drives. The HP drives have been very reliable There a a lot of backup strategies. They fall into two categories IMO. The first is the selected backup. This refers to specific files or directories of importance. I would recommend 100 MB media for this type of backup. This includes LS120 and zip drives. The second is a complete partition backup. This procedure requires media equal to or greater than the partition being backed up (except in the case of compression). This is the more difficult of the two. CD media does not lend itself to either one of the above categories. Random access is helpful in category one (selected file backup). Category two (complete backup) can benefit from random access however linear tape may not be a significant disadvantage for this type of backup. Tape can be scheduled for backup in your absence. One should design the software load with backup in mind. Read through some of the old posts. Not much has changed since then. home.att.net home.att.net One consideration is a GB Syquest drive coupled with a harddrive with three partitions. (Dave Hanson's strategy). Going from memory, I believe he uses a small primary partition for the OS, 200 MB?. Then a larger partition for the data and applications. The third partition is for backups of the first two partitions. The backups are also copied to the Syquest removable drive. Drive Image is used to make the backups. Did I get it right this time Dave? BTW I'm looking forward to the new index threads. I think its a good solution to at least try out and evolve. I imagine we'll access them via the Clubhouse The index is not accessed through the clubhouse. The index is accessed by using the SI thread bookmark option to bookmark the Dream Machine Subject thread #Subject-23122. Click on the most recent post in the subject thread to access the index. Then click on the subject of interest. Then click on the most recent post in the category thread. If the idea works out we will ask Brad to add the link to the header of the Dream Machine thread. The clubhouse is so two people do not try to index at the same time. When I feel more confident in my understanding of PC subjects I'd like to partake in some indexing. Help is welcome. Jump in whenever you feel comfortable. Subjects are not a big deal. When in doubt put a post in two or more categories. If you work on the index indicate you are doing so in the clubhouse. When you are done indicate so in the clubhouse. This will avoid confusion and duplication of effort. Zeuspaul
