i was able to reconstruct and authoritatively back up my archival material a lot easier than i thought i would be able to. the only thing i've lost of any consequence is a couple of backing files for 'ignorance is bliss'. i can live with that.
now that i'm a little more focused as to what i'm looking for, i'm going to do one more data recovery scan through the other two physical disks to see if i can salvage anything. i'm not overly confident.
as for the script? i did this once before and concluded the data was garbled, but if i can reconstruct the directory structure and file names of the script, and get a bit lucky in pulling out a few text fragments, i should be able to rebuild the script with minimal effort - even if it takes a few days to write it all out and do some virtual testing. well, shit, it could be a month before the bus pirate gets here, anyways.
i'm going to move some things around with the expectation of getting used to living with three discs for the time being. i'm not sure i could even buy a 250 gb sata II drive new anywhere (and second hand hard drives are a dumb idea). so i'm going to end up upgrading.
when i do, i'll move the music files to the new drive. they're both the most important and need the most space. that'll leave me with two 250s i can boot into 32 and 64 bit, respectively, and one to use for various types of backup.
for right now, though, i don't have the appetite to set up a 64 bit system. but i might end up at least nliting it, depending on how much time i end up waiting for, and how successfully i can salvage the other laptop.
as the problem with the other laptop is the hard drive (there's a pattern here; i'm tempted to go to ssd, i'll have to check prices), what i'll have to do is work off an external. then again, it hasn't actually died yet. in the long run, that's another component i'll have to replace, but it's not a priority.
so, i'm chugging away at this. i can't provide an eta for getting back to what i was doing, but i can at least report having a few ideas.
