Cleaning Amiga floppy disks – success!

It seems an extremely long time since I’ve updated this with any Amiga stuff, so I thought I’d do a quick update.

It’s a disgustingly wet August Saturday, and I’ve recently been accumulating more Amiga disks off ebay, and imaging them with the good old Greaseweazle, which is still going strong.

As part of the process of imaging them, I’m also grabbing the file listings off the disk, and putting them into a database. This is, so far, a long laborious procedure, and at the moment, I don’t know what purpose it’s going to serve, but doing this at least gives me a chance to test that the disks have ripped successfully, at least to a point.

Anyway, as the afore-mentioned weather is cack, I thought I’d spend an hour or two goiung through some of my recent images and getting rhe file listings. Anyway, after about 4 disks, I got the dreaded “read error” message one one of the disks I’d imaged.

Not fun. I loaded up hxc to check the disk image in a more thorough way, and sure enough, there were two bad sections of the disk, one on each side.

I went through and checked the disk, and there they were… mould spots.


Ugh. The bain of any old media collector. It’s just something that happens. These disks must be… oooh, dunno. 30 years old now, so any slightest but of organic material that’s crept on the disk in that time has obviously been taken over.

I’m surprised I didn’t pick up on this when the disk was getting images. A mould spot this severe would have definitely created a tell-tale noise when the disk was being imaged – a definitive click-click-click as the mould spot makes contact with the head, about once every 1/20 of a second.

Anyway, I had hopes of resurrecting this one. I took a tiny bit of IPA on the end of a cotton bud, and very lightly rubbed the surface. You don’t want to put any pressure on at all. The surface of the disk needs to be perfectly flat, and any slight ripple in the surface will render the disk useless and the data gone.

I didn’t get any pictures of this, so I don’t think you need much of an imagination to picture what I did.

Thankfully, the mould was no match for the IPA, and within seconds, it was lifted. I used the dry side of the cotton bud to remove any possible residue, and left it to dry for a couple of minutes. Obviously, IPA dries on its own really quickly, but the last time I tried this, I must have put far too much on and ruined the disk, and possibly didn’t help the drive much either.

Of course, the proof of the pudding is worth two in a bush, so did the disk actually work after I’d tried all this?


Oh, I’d say that was a success.

As a side note, I know I was holding the disk myself. I’m aware that you can buy little disk cleaning cradles that will hold the shutter open for you while you do this. I actually have one, but didn’t have it to hand when I did this.

Back To the Greaseweazle

A title that makes this sounds like either the greatest movie of all time, or quite possibly the worst. Anyway, as the title suggests, I have returned to imaging some more Amiga disks that turned up on ebay. I think I’m up to my 7th batch, and they seem to get better with each iteration. The last ones I purchased appeared on ebay a few weeks ago, and some of the disks themselves sertainly piqued my interest. They were slightly different to the normal batches of copied disks and coverdisks. I have plenty of those now, but these looked like they actually had some “productive” stuff on them, at least some interesting utilities that I could install.

There was one disk, however, that certainly piqued my interest…

3,000 database records… the previous owner had even taken the time to say how full the disk was, and how long it took to load. Sadly, no mention of what software was going to be used to open it.

The box arrived. I feverishly opened the box, and looked for this particular disk. There is was, in all its shiny blue glory. The Greaseweazle let out a little cry of pain, as I stuck the USB cable into its back passage. I fired the software up, and within minutes, I had an image of the disk. I loaded it up, aaaaand….

Yep, the previous owner had thoughtfully formatted the disk! I could have cried. Ofcourse, anyone who knows anything about computers knows that formatting a disk doesn’t actually delete anything, it simply clears the areas of the disk such as the file allocatuion table, or whatever the Amiga equivalent was. The data is usually still there.

Aware of this, I opened “DiskSalv”. As the name suggests, it salvages data from disks… no other way of making that interesting, really. I let it work its magic, and within a minute or so, it had recovered the files!

This is where the trail went slightly cold. I had the files, but didn’t know how to open them. the file names didn’t ring any bells, it certainly wasn’t anything I’d used before. Helpfully, the next disk in the box was labelled as the following!

Now, I won’t waste much time on this, because… the disk was once again formatted so I went through the same procedure of salvaging, but sadly, the only file on the disk was unusable. I might dig into it a bit later, but I have a feeling the file is corrupt.

About 5 seconds of forensic investigation led me to find that the database would open in a package called “Mini Office 2″…10 seocnds of downloading, and 10 minutes of trying to get the bastard thing to boot. Eventually, there it was! Mini Office in all its glory, and the database turned out to be someone’s music collection!

Oddly, the majority of the records appear to be duplicated over and over again.
Maybe the previous owner was using it to “benchmark” his Amiga, hence the writing on the lebel?

Of course, this is very likely something I’ll never find out. There’s plenty more disks in this box for me to go through, but I doubt they’ll be as interesting (for want of a better word) than this one. Meh, it kept me entertained for a few hours at least.

Super Plorrds. It’s super.

Ahhh yes, the Greaseweazle is the gift that keeps on giving, and I’m happy to report that I’m not the only one enjoying its greasy goodness.

You may remember, waaay back in the early days of the blog (in a post that’s probably hidden now) , that I talked about an Amiga game I used to play, called Plorrds. It came free on an Amiga Power coverdisk, and I loved it. Played it for hours. I even partially put it down to my crap GCSE results, as I spent so many hours staying up and playing it. Of course, the real reason might have been that I’m just a bit thick, therefore I like to blame the former.

Back in 2001, I started a job at a (now long defunct) company. The first person to introduce me to the company, was a bloke called Glen. At some point over the next few years, myself and Glen got talking about the Amiga.

At some point, the words “Plorrds” got dropped into the conversation. “Oh Yeah, I remember that!” I said, excitedly. Glen responded with “Well, I programmed it”. If there was a sound of a jaw hitting a desk, it would be a sort of “fop” sound. I couldn’t help but feel like I was in the midst of a celebrity.

Fast-forward a couple of months or so. The date is November 5th, 2001. I had just invested in a shiny new Amiga 600 (shiny and new aren’t exactly words I’d use for it, but at least it worked), and was rooting through some of my old disks. Out popped Plorrds. “Huzzah!” I thought, as I plonked the disk in the drive, and waited patiently for the menu to come up…. aaaand “Disk read error”. Oh. It turned out the disk was completely ruined. 

At some point during the intervening 21 years, Glen mentioned there was a “Super Plorrds”, but it had never got released. After my (many) posts about the Greaseweazle, Glen contacted me and asked if they were worth getting, as he had a large amount of disks from back in the day that he wanted rescuing.

I advised that it was exactly what he was looking for, so he rushed out and bought one… Or rather, sent away for one.

A week or so later, he sent me a message confirming it was all working. Of course, my next question was if Plorrds still existed.

“Even better than that”, he replied. “The unreleased Super Plorrds still exists”, and I could have the exclusive first look!

As promised, an email plopped into my mailbox a short time later, with a disk image attached.

I fired it up, and I was transferred back to 1995, albeit with more music, different colour scheme, and even different gameplay.

The premise is extremely simple. You start with a grid of numbers, half with plus figures up to 10, half with minus figures up to 10. The trick is, one player can only move horizontally, and the second player can only move vertically. The winner is the player with the highest score. Obviously. The game ends when all of the squares are gone, or a player can no longer move.

The trick is to plan ahead. You COULD go for just the highest value square, but before you know it, player two could lure you into a row of negative points. The real trick is to plan ahead, even sacrifice a few points, if it means your opponent can do nothing than lose more points than you. It gets trickier when you start running out of possible moves, and your massive lead could be wiped out within a matter of moves.

If you play the CPU, there are a number of difficulty levels. I’ve been playing the game for almost 30 years and I’ll be lucky if I can get past level 4 or 5. I don’t think I’ve ever played another human at it. It’d be great if that was a thing, as after almost 25 years, I still royally suck at it…

QUICK UPDATE: If you’re wanting to try this out in WinUAE and don’t have an official Amiga ROM, it appears to work just fine with the AROS ROM that ships with WinUAE. I’m not sure if Glen’s actually put a link to the game up yet, but I’ll update this if/when he does.

The disks! They’ve arrived!

I’m happy to report that the disks were handed to the guards at Mercuryvapour Towers, and not just thrown over the portcullis. I now have in my possession 100 floppy disks, Woohoo!

I rushed hurriedly upstairs, with my precious cargo under my arms. I ripped the cellophane off, to be confronted with a nice neat cardboard box with “MISC BACKUPS” written on the side. No signs of mould / damp. No smell like they’d been rotting in a pool of water for 20 years. Things were looking promising

The sellotape holding the box shut looked like it had been there for a long time. This was a good sign. Someone had clearly backed these disks up, then filed them away. I guess it meant that they hadn’t been touched, and had data on them.

I was even more impressed when I opened the box. 10 neat boxes of 3.5 floppies. All of the same make. I was even more impressed when I opened the disk, and found that each disk had a protective sleeve on them too! I couldn’t wait to try them. Each box even had a little label on them saying what was in there…

On goes the PC. The Greaseweazle lets out a little squeak as I stuck the USB cable up its grundle. We were good to go.

Firstly, just a random disk. Just to make sure it was all going to be working. Everything sounded perfect. Not a single unexpected noise from the drive. These disks were perfect. time to fling it into hxc and take a look what’s on them…

Waaaaaait, what? Why does that disk look like it’s only formatted on one side? Was the drive dead? I stuck in my test disk, and it came back fine. Both sides read correctly. I’d noticed that it had actually recognised the disk as a 360K formatted disk. I didn’t even know this type of thing existed. One thing had became very, very clear… These disks waren’t going to be reading in my Amiga emulator any time soon.

I read a couple more. These came back as 720K disks, so I checked the files. They might still be of use if they had PC compatible stuff on them…

ATARI ST'S.

Oh, well isn’t that just effing marvellous. I now have a nice box of 100 disks that are only useable in a computer I have absolutely no interest in owning or emulating. Well, there’s my night’s entertainment (and £30) down the bloody kermit. I suppose I could still image them and stick them somewhere. Don’t know what I’ll do with them after that.

So, this post is a lot shorter (and infinitely more disappointing) than what I was anticipating. Still, some you win…

FOR SALE: APPROX 100 ATARI ST DISKS…. anyone? £31?

More Amiga disks on the way!

You may have noticed I’ve not used my Greaseweazle for a couple of weeks. The supply of decent disks has dried up. There’s still quite a few old games to go through from that mouldy box, but I don’t fancy killing the drive if I’m honest.

Up steps ebay again. You may remember my Arcade Pool success, where i ended up getting an image of my favourite game working? Well, I took the plunge. There was a “Buy It Now” listing, with 100 Amiga disks in there.. Well, I just had to, didnn’t I? Yoink.

It’s currently on the way, and due to be here some time today. I had to quickly rewrite this, as i didn’t expect it to be turning up on Good Friday, but it seems like it is. 10 points to the delivery company, then

It could be a complete disaster These are “untested” – a word that should really strike fear into the hearts of any ebay buyer. For all I know, they could have been picked up out of a swamp… although I doubt Newton Aycliffe is known for its marshy ground. They could all be incomplete copies, or all have read errors. For all I know, they could have been already checked, found to be duff, then bundled into a box, ready for some sap to pick them up off ebay.

They might have already been wiped by a previous owner, meaning I’ve bought 100 blank disks.

There’s a large chance that I’ll do a blog, or a video. Allegedly, they’re arriving in one box, split ino 10 smaller boxes of disks, so I’m genuinely intrigued to ee what /i get. It’ll make it easier to do a series about them. Maybe 10 or 20 at a time.

Oh. I’ve just read the email. It’s getting delivered by Hermes.

Fudge.

Opening files from Amiga disks on the PC…

A nrecent commenter asked about the disk images that I’ve recently created… “Can you browse the contents of the disk images you create without loading them imto an emulator”?

The answer is… “Of course.”, and it’s all done using HxC. (Note: Not to beconfused with HxD, the hex editor).

I can’t remember if I mentioned HxC in any of my last posts, but it’s what I’ve been using to get those pretty green circles as shown in my other posts on the subject, but here it is in all its glory.

To load your freshly created disk image, you can either click “Load”, or drag the file onto the program.It’ll confirm it’s loaded by giving you the file name.

Click on “Disk Browser”. If it’s in a format that’s recognised, such as PC DOS, Amiga DOS, etc, you’ll see the disk contents. Note that this won’t allow you to read the files on protected disks / ones that aren’t in a standard format, but hopefully you expected that…

After that, the files are saved onto your computer. Naturally, what you’re able to do with the files is going to vary wildly. In my example, thankfully, the IFF / ILBM image format, along with the HAM variant, open up in a few modern programs. My example below is from XNview MP.

That means if you have a disk of images you made with Deluxe Paint back in the day, there’s a very good chance you’ll find something to open them with. Sadly, the GIMP, as of version 2.10.30 doesn’t want to open these examples. Shame.

It’s not going to do any harm to have a bit of a play around

Arcade Pool… it WORKS!!

I’m a happy little camper right now.

You can’t have failed to mention that in my last post, I drooled a bit about getting “Arcade Pool” for the Amiga through the post. It’s a game I’ve had pretty much since its day of release, but my disk really will have seen better days. I know for definite it has no metal cover, and although the last time I fired any of my amigas up in anger back in 2006, it worked correctly, but I wasn’t taking any chances. I just ordered an original loose disk off ebay.

I checked today at the base of the Mercuryvapour Towers portcullis, there was a box staring up at me. Strangely familiar, yet also alien to me. For you see, a box for “Make-A-Chip” on the ZX Spectrum stared back at me…

It soon dawned on me that this must have been the “Arcade Pool” disk in some very innovative, and perfectly suitable packaging. Eventually, after a night at the pub, I sliced through the parcel tape, and yes! there it was!

Now, I originally planned to do a video on this, it was filmed, but it’s awful, so instead of fresh photos, you’re just getting screenshots instead.

So, the image above is, of course, the disk, fresh from its cardboard catacomb.

In it goes, and I fire up the disk image program. My heart sinks just that little bit… Click-click-click-click… This usually means the disk is warped / damaged… usually if a speck of dust has been pressed against the disk surface, causing a lump or a mark.

The clicking fades shortly after. I’m left with the faint rumble of the disk spinning, and the soft, rhythmic clunk of the head moving across the disk. Eventually, all 82 tracks are imaged. I go to make sense of the disk image…. aaaaaaand…

Those red sectors stared up at me like blood in a stool. It’s not always as bad as you think, but you’re programmed to think the worst. Those blue “unrecognised” sectors didn’t have me holding out much hope either. Had it worked? Was I about to relive my childhood? I fired up WinUAE. My voice in the video didn’t hold out much hope. I even said so in the video. I loaded the disk image, and watched in surprise, joy, and just a hint of speculation, when the company logos came up, followed by the screen I expected to see…

Mere seconds later, I had the title screen, as the sounds of Scott Joplin’s “Fig Leaf Rag” rang through my speakers…

It worked! The blue sectors are a by-product of the custom disc format it had used back in the day. Annoyingly, because of this, I was never able to make a backup copy of the disk, which is how/why my original disk survived, albeit in an unknown state

It soon became apparent that everything in this Amiga journey had came full circle. My rekindled love affair with the Amiga started on a Sunday afternoon in February last year when I came downstairs and Daddykins was watching a steam train video that happened to be playing the “Fig Leaf Rag” as its background music. It suddenly occurred to me just how much I missed Arcade Pool, and just the Amiga in general. I rushed upstairs, installed WinUAE, downloaded a disk image of the afore-mentioned pool game, and had a right old time but where was the fun in that? This wasn’t the original disk.

The fun has been in the whole journey I’ve taken in the last year. Managing to convert my original Amiga drive, finding out some of the stuff on it, reliving some of the many memories I have stored on it.

There has, of course, been downsides… Discovering the box of Amiga stuff I bought a few years ago was completely rotten. Constantly corrupting my hard drive image and having to start from scratch with it… my fault for not regularly backing it up I suppose.

Oh, just one quick thing on the Arcade Pool image. While checking the disk image, I noticed some text in the first sector of the disk…

Version 1.01 - May 1994 - pippistrello pippistrello, perchè hai fatto la pipi dentro all'ombrello?

Now, my Italian isn’t the best, so I had to rely on Google Translate for this one, but it comes back as roughly “Bat, do you think it is nice to pee in an umbrella”? It made me smile somewhat. the fact that I’ve owned an original disk of this software for 28 years, and have only just discovered this, amuses me greatly.
