Recovering data from an old large hard drive out of a 486. Someone asked how. No problem.
What do is put both drives in a new(er) system, each on its own IDE channel as master, then autodetect the old drive with the BIOS’ autodetect drives feature. But, to be on the safe side, I don’t boot Windows. I don’t want anything to try to write to the old drive, because it may not work right the first time. Instead, hold down the control key while booting (if you have Win98; if you have Win95, start tapping the F8 key immediately after the BIOS boot screen comes up–if you get a keyboard error, hit F1 when it says, then resume your attack on the F8 key). Select Safe Mode Command Prompt Only from the menu. That will put you at a C prompt.
Your old(er) drive will be drive D. If you had other partitions on the drive, they’ll be lower in the alphabet as Dan said. We can tell you exactly how your drives will be mapped if you remember your partitions (or maybe you’re familiar with how drive letters get mapped already).
Now, I execute a DIR /S D: to see if it produced an error. If it doesn’t, try this to get your data (don’t type the comments in italics):
MD C:RECOVER create a destination for your data
SMARTDRV D- turn on disk caching to speed up –may not work but does no harm
XCOPY /S /E /V D:*.* C:RECOVER copy drive D in its entirety to the destination
With any luck, that’ll safely spirit all your data away to the new drive. This is more convoluted than using Windows Explorer, but it’s safer. (See why I disagree with the people who say command lines are evil and obsolete and we shouldn’t have them anymore?)
If that succeeds, power down, disconnect the old drive, boot Windows, and check to make sure your data is intact and not corrupt. If it fails, reboot, go into the BIOS, and change the translation scheme for the old drive (you have a choice between Normal, Large, and LBA–LBA is usually the default). Lather, rinse, and repeat.
The good news is, I’ve used this method numerous times to move data from old 486s to newer machines, so chances of success, though not guaranteed, are pretty high.
Maybe I don’t want that Amiga 1200 after all… I went ahead and downloaded UAE 0.8.8 Release 8, then downloaded Amiga In A Box, which gives me a nice, souped-up Amiga setup without me having to remember all the nuances of the OS and tweak them myself (including some nice PD and shareware stuff already installed, configured and running). I fed it my Kickstart ROM image and my Workbench disk, it copied the files it needed, and voila, I had a working AGA-compatible Amiga!
The package even includes TCP/IP support. While Web browsing on a 33 MHz machine is a bit slow, I found performance to be almost as good as Netscape 4.x on a 90 MHz Power Macintosh 7200.
I benchmarked it, and on my Celeron-400 with a pathetic Cirrus Logic video card (I really need to get a cheap TNT2) I still compared favorably to a 33 MHz Amiga 4000/030. (My old beloved Amiga 2000 had a 25 MHz 68030 in it.) Since the Amiga’s biggest bottlenecks were with the disk subsystem and the video–they were comparable in speed to the PCs of 1990 and 1991–even a slow-sounding 33 MHz machine runs pretty nicely. I could probably crank out a little extra speed with some tweaking, which of course I’ll do at some point.
Then again, maybe I’ve finally found a use for a 1.2-GHz Athlon… (Besides voice recognition.)
If you have an old Amiga laying around and want some nostalgia, go get this. There’s a ton of legal Amiga software at www.back2roots.org to experiment with. If you don’t have an Amiga but want to see what all the fuss is about, you can get Cloanto’s Amiga Forever package, which contains legal, licensed ROM and OS images. You’ve probably never heard of Cloanto, but they’re one of the largest remaining Amiga software publishers. They’re reputable.
Now I just need to get TransWrite, the great no-nonsense word processor that I bought when I first got my A2000, running under UAE.
