I have brochures (somewhat dated), or you can check out their web site (which, last I looked, was mostly in German) at http://www.hnf.de/ . Never been there myself, but it's on my list if I ever get around to a European Tour. -Frank McConnell

taking care of bad sectors... easy stuff. Was: Re: hard drive data recovery

by higginbo＠netpath.net

I'll bring it back on topic: Spinrite is some powerful hoodoo. I used it alot on Seagate ST-225 drives. I'm never one to use any questionable sectors though: Some of those drives had less than 10mb when I was through with them. I don't trust iffy sectors.

hard drive data recovery

by maxeskin＠hotmail.com

If you are removing a head arm and working on it, you can wrap everything but the actual connection in clean plastic. I wouldn't expect smoke particles to magically fall off the arm onto the platter, even if the arm is upside down. Plus, smoke travels upwards, and I would expect little of it to settle if you use a fan or something. As soon as you finish soldering, take it back to the clean box, and put it inside to let it cool off or to reassemble (unless it's still smoking). As for doing activities which involve platters, that's a trickier thing. I have no idea what you would do if you had a problem with the motor or the axle on which the platters are mounted. Now, my question. Let's say a single head crashes. This would raise up some dust off the platter, right? Would it be possible to recover the material that wasn't destroyed by the dragging head? What if this deformed the platter? >Serious question. What do you do if you need to resolder a head >connection or something?

taking care of bad sectors... easy stuff. Was: Re: hard drive data recovery

by poesie＠geocities.com

well, I personally have never opened up a hard drive, if nothing else because I've never had an extra to pop open (i'm too frugal. hehe.) Regardless, I have found the program "Spinrite" to work great on IDE drives; it goes through and can fix bad sectors, or mark them totally unusable. this really differs from standard formats/etc, because I've been able to take drives w/ 30mb of bad sectors and get it to 0 bad sectors, and still running fine w/ no problems after a year. i believe they are on version 5, i got version 4 for about 20 bucks. This is kind of off-topic and doesn't cover a whole lot of you out there, but when you buy a box of 100 drives that are all "bad", you can sometimes salvage quite a few of them. -Eric

by SUPRDAVE＠aol.com

In a message dated 98-07-14 11:45:07 EDT, tony duell put forth: << > BTW, how common are PC-jr machines without floppies? Were most of them > upgraded? >> all pcjr machines came with 128k and one floppy drive. i have seen "second story" units that add another floppy drive. it seems to be there used to be an aftermarket for the jr, but a hot-rodded one still wouldnt be as good as a standard xt though. a popular modification was to bring the machine up to 640k by soldering in some dip chips in the 128k add on sidecar thing. i believe IBM has a file on the www searchfiles page that still tells how to do this. david

hard drive data recovery

The actual sensor is a sealed unit, just like a transistor or a vacuum tube.

by maxeskin＠hotmail.com

Well, I think that the default lack of floppy drive was a mistake, as was the lack of RAM. I'm not sure what year it is, but I believe 640K was standard by then. Also, I have the Getting Started manual for the PCjr. It's supposed to be a technical reference with specs, and details on how to prepare it for shipping (like in the IBM PC manual of the same name), but instead it has childish junk on how to use cursor keys (it has a little cartridge game called the keyboard adventure, with a little guy that can move around). Techinicians reeely don't like that. >Apart from the IR keyboard, which was a mistake ;-), it's basically a PC >without the DMA chip, but with better-than-CGA graphics.

The 19" racks were generally black... there were attachments to the top of them which were different colors. The purple series was indicative of the pdp-11s (which match the time-frame).

Maybe I'll provide my full list in a later message, but for now, you can check my 'home_systems' page off my home page... >> DIGI-COMP 1 (an educational toy from 1963) > >Way cool.

I remember when I was in fifth grade or so, my father ordered one for me. When he received it, he thought it was too complex and simply put it away. One day I came across it, and before he came home that night I had assembled it and was working on some of the programming examples. I have a set of documentation for it (sent to me by someone a few years ago) and I would LOVE to get one for my collection...
