I tried to make a disk image with TI (all my partitions - 4 of them - on a 20GB HDD), but I ran out of CD-R's before I could complete the process. I had 4 blank CD-R's on hand, but the process asked for more than that (I saw that it had only completed slightly less than 50% with 3, so I knew before I put that last one in that it wasn't going to finish on just 4 - but I was hoping . . . duhhhhh). So, I aborted the process and will go back to the store and get some more CD-R's before I try it again. But that experience gave rise to a question about compression. I had "Normal" checked (which I think is the default in TI). There is a "Maximum" and I'm wondering if I should have used that (if I had, I might not have wasted 4 good CD-R's). The CD-R's have a capacity of 700MB. I had expected TI to only use . . . ONE . . . CD because I thought that Disk Images were written in binary code, which as I understand it takes up much less space. Plus, Restore CD's from manufacturers are only typically one CD (or at least they used to be, but with today's larger capacities maybe there's more than just one supplied by a manufacturer). I have an HP laptop, purchased in 2004, and instead of a Restore CD, HP included a Windows (XP) CD and a Driver CD. But before that I had a WinBook, and WinBook did provide ONE CD as a Restore CD. Anyway, whatever manufacturers are doing nowadays, as I said I only expected to have to use one CD. Maybe I shouldn't have expected that. So, my questions: 1) Just how many 700 MB CD-R's would I have to use with normal compression in order to make my disk image?? 2) Should I use "Maximum" compression?? As I understand that scheme, it only takes more time. 3) If I used Maximum compression, then how many 700MB CD's would it take?? 4) Should I buy a big (2GB??) Flash Drive for my image?? Oh . . . and one more thing . . . I don't use CD-RW's for two reasons: 1) They are much less reliable than CD-R's. The manufacturers say they're good for 1000 rewrites, but in my experience they're only good for about 20 rewrites. After that there's a substantial risk of corrupted data. I used one once and I lost a bunch of data on it after about 20 or so rewrites - NEVER AGAIN!!!! Now I use a Flash Drive for that purpose. 2) CD-R's are cheap enough nowadays (about 10 for $10 bucks at WalMart), so it makes sense to reduce the risk of data corruption at that price (assuming your data, and peace of mind, is worth that much).
