Title: SFS and PFS won't work
Post by: RCtech on October 21, 2015, 01:04:34 PM
Hello,

after some years I'm rebuilding my A4000T again. It works rather fine, but I have problems with filesystems - only FFS works. Additional hardware is a Cybervision64/3D with Scandoubler, Cyberstorm MKII/060 with 128 MB RAM and 12 MB RAM on the board - the leftmost (S354) is empty.

I'm using the standard 4000T controller with an Maxtor Atlas V 146 GB 10k drive und an 50->80 adaptor. These drives are awesome, when powering on they make for about 10 secs some self test clicks, then the drive is absolutely silent and doesn't get too hot. The Atlas V is also available in 73 and 300 GB.

I'm still in preperation, booting partially from floppy or MO drive. I'm using WB 3.1 with the AmigaOS ROM Update from 3.9 and HDInstTools 6.9. The Maxtor Atlas is fully recognized, low-level-format works, 560 cylinders are 682 MB. Formatting FFS partitions is no problem, either from HDInstTools or Workbench.

So, now I wanted to use SFS and got the latest package from the aminet. I loaded it into the RDB with DOStype SFS\0 and changed the filesystem in the partition settings. But it won't work. I tried the default Mask/Maxtransfer values 0x7ffffffe/0xffffff, the ones I found in the net 0x7ffffffe/1fe00 and the ones from the SFS_old.guide, 0x7fffffff/0x7fffffff, and combinations. Buffers are mostly 100, or the default value 30. Nothing works. I also tried to change the DOSType to SFS\2, no change. I could format a partition using SFS\0 in HDInstTools, but after the next boot the partition isn't visible, although it is listed when you type 'assign devices'. SFSformat crashes with a software failure when your're trying to format this partition, this also happens if you are trying to boot from it. The partition is listed in the Early Startup Menu.

But PFS won't work, too. I think I had the Direct SCSI version, so I tried PDS\0. Nothing, like with SFS HDInstTools got the error messages 'format failed' or 'object not found'. Something else is weird: If I'm changing a SFS partition to FFS and reboot, it is visible as DH0:SFS0. So the formatting must have worked earlier. Unformatted FFS partitions are automatically as DHx:???? or similar on the Workbench, but there was never an icon of a partition with another filesystem visible.

Do you have some ideas? Could it be a software problem? The 68040/68040old/68040new/68060.library are from the BlizzardPPC disk, but I also have another version, not tested yet. The ROM Update, NSDPatch and SetPatch are from one of the BoingBags, not from the 3.9 CD. The same MO also boots on my Amiga 500 with A570 and 3 MB RAM. I have no idea why this doesn't work, I had it working years ago on my A1200/040, A1200/PPC and the A4000T. Any help would be appreciated.

Greets, RC.

Wonder if the RDB has got confused? Can you delete all file systems from the RDB and then confirm they're gone? Only do this though if you don't care about your data on your drive - I don't want to be the one responsible for you loosing any data.

Also, after changing file systems or partitions I always power cycle the machine to properly refresh the changes.

After confirming you have a clean slate, then install your first file system and partition and check the mask and maxtransfer and dostype are remembered. TBH, I use HDToolbox as supplied by Commodore as it always seems to work (you have to press enter in the boxes though before saving changes for it to remember maxtransfer/dostype and any other keyboard input).

Then confirm changes. Quick format. Then, move onto your next file system.

P.S. SFS v1.279 is the latest version, not the one on aminet. I can't remember where I downloaded it from though, sorry.

Avoid third party filesystems, they come and go and reappear in incompatible formats etc.

I erased the RDB with HDinstTools, switched the computer off and turned it on again, created the partition, but still the same problems. If I'm trying to boot from such a partition, I'm getting a Software Failure window without task name and the error 80000008. I searched for it and it could be the 68060.library, actually I have 43.1 installed. I'm trying to install a newer one.

It's a bit difficult to transfer files: I don't have any computer with a disk drive. And the A4000T has no CD-ROM or driver. But my A500 has - in form of the A570. I didn't think of this before, but I was talking with a friend about an old PC-CD-ROM with caddies, then it came like a flash of light ;-) Now I have to burn the files to a CD in ISO9660/RockRidge format, then have to copy the files to my MO. This is helluva slow - not only because it's a 7 MHz A500, but a single speed CD drive and MO writing are all adding up slowness. MO's are writing very safely - first erasing every sector, then writing, then verifying. But that's rather slow.

Now I have to remember which programs, addons and DOS commands I used years ago - I have to start completely from scratch. And I don't want to waste a CD for just 200K, so I have to find enough stuff to fill 700 MB ;-) But it's still fun somehow. BTW: Does anyone know where to copy the BrowserII keyfile? I used the files from the Aminet, but I'm still getting the unregistered message.

I'll doubt this will help. Yes, there are certainly newer ones, and certainly better supported ones, but: The 68060.library comes in as part of SetPatch, and thus way, way later than the bootstrap function loading the file system from the RDB.  Second, Guru #8 is a priviledge violation, i.e. the code tries to execute a statement that is not available in the user code. This could have multiple reasons. For one, executing a MOVE FROM SR command on a 68060, where this command is priviledged. If there are multiple versions of the file system, then try one that is for the 68010 or above where this opcode cannot be used anymore.  However, I would rather believe that something else went terribly wrong and the code just run amok. How did you install the filing system into the RDB in first place?  This being said, I would not be surprised if the binary of the filing system simply got corrupted in your complicated installation procedure. I would check for the MD5 checksum of the file before the transfer, and check it again afterwards. There are (hopefully?) some tools available for the Amiga that can help you to compute the MD5 sum.

It might be worth salvaging an old ide CDROM from a PC if you can find one and fitting it in your A4000. Will save you a lot of time.

The Workbench 3.1 install disks have a basic CDROM driver that's easy enough to use.

Or even easier would be to fit the hard drive from your A4000 in a PC and prep it from UAE.

I have a 73GB Maxtor Atlas V 68 pin on the CSMKIII SCSI. I would get a Guru before booting with SFS. PFS works fine with the last official version of PFS TD64 but I would use PFSAIO for a new install (PFSAIO DOSType selection is easier and it has better large drive support). I strongly recommend the boot partition to be <4GB and to use 512 byte sectors. Do not do more than a quick format and it is best to use PFS format (with long file names selected) for formatting especially for partitions >4GB. If you can't get at least this boot partition to work then you have major problems.

Well, it's no matter what filesystem I'm using until it's not FFS. If the partition is not vaildated it takes millions of years until a large partition is finished. I has PFS3 earlier, but it used a lot of space for metadata. OK, wouldn't be a problem anymore. Which version would better, standard PFS oder PFS direct SCSI? I thought on using SFS because it seems to be a standard now, at least MorphOS and AROS are using SFS.

Why should't I use HDInstTools? I was always using it. HDToolBox from 3.1 wouldn't be a very good choice, and I'm not planning to use 3.9. Is there another partitioning tool?

I read in another forum that a guy had the 80000008 problem on an A1200/060. He updated them and the problem was gone. So I'll try this, and it can't be bad to have newer versions.

Actually I can't add any more stuff because my A4000T setup looks like this (http://www.bilder-hochladen.net/files/big/c4q7-ju-85e4.jpg). The system gets a new E-ATX case and it has to be modified for the Amiga. If anyone has the schematics of the ports board, that would be great.

OK, as long as you are only using HDInstTools I suppose it can be safe, I tried to use it a few times and it only led to all kinds of strange problems.

Only FFS needs to be validated and this process uses a lot of memory for large partitions.

Phase 5 hardware usually has good support for TD64 making it a better choice than DirectSCSI but DirectSCSI should work everywhere. I believe PFSAIO will query (and maybe even test) the hardware before selecting TD64, NSD or DirectSCSI as appropriate.

It is bad to mix HDToolBox and HDInstTools. There also may be some bugs in HDInstTools but the AmigaOS 3.1 HDToolBox doesn't handle >4GB partitions very well either. Upgrading to AmigaOS 3.9 with BoingBags would give better large HD support including an improved version of HDToolBox.

Looks like my A3000 at the moment. :lol:

SFS across 68k, AROS, OS4 and MorphOS are incompatible forks for the most part. PFS3 is compatible in all its variants.

Post by: RCtech on October 22, 2015, 07:06:30 PM
Well, I'm not using HDToolbox anymore. It isn't even compatible to MO drive until you've patched it. The HDToolBox from 3.9, AROS and MorphOS is very complicated in my opinion.

HDInstTools has some problems with too big harddisks while partitioning.  A 300 GB drive with one partition is shown with about 7600 MiB, the  Cylinders section is distorted when the values are too big. The size  slider creates some weird results, but the size display is correct. The  drive info is also correct, I also made a bad block check and had one at  324.146.587.

One big difference from HDInstTools to any HDToolBox version is that it shows the partition layout, but you can't work with it. So it's difficult to  modify free areas of the drive. You can avoid problems if you're planning the drive from the beginning on. I'm always using 6 system partitions in the 4 GiB area:

1 - Workbench 3.1
2 - Workbench 3.1 Backup
3 - Workbench 3.9
4 - Workbench 3.9 Backup
5 - System
6 - Temporary

The first are easy, the System partition is an addon partition which are used by all partitions. This is useful for additional libraries, huge font collections and more. You just have to check in the startup-sequence if this partition exists, then you can assign or assign ADD these directories to your system. So on the boot partition just have to stay the important files you need, this saves space and the partitions can stay smaller. Workbench 3.1 and 3.9 can use different libraries by checking the system with the version command. Each partition is 682 MiB in size, so they're all below the 4 GiB border. The size useful because you can backup it easily to a CD or a 640 MB MO, here it is even bootable.

I'm always partitioning by cylinders. This needs a bit calculation, but it's safe. I now have all models of the Maxtor Altlas V here, and all have different cylinder/size values. By the way, I'm using the expressions MiB (Mebibyte) and GiB (Gibibyte) because its using base 2, not base 10 (MB, GB) like it's written on hard drives. These are the values:

Maxtor Atlas V 73.4 GB version

1 GiB = 7768 cylinders
4 GiB = 31072 cylinders
682 MiB = 5178 cylinders

Maxtor Atlas V 147 GB version

1 GiB = 17478 cylinders
4 GiB = 69912 cylinders
682 MiB = 11652 cylinders

Maxtor Atlas V 300 GB version

1 GiB = 6991 cylinders
4 GiB = 27946 cylinders
682 MiB = 4660 cylinders

So I'm using 6 partitions to 682 MiB. To match exactly the 4 GiB border, the 147 GB version can use 6 partitions without modifications. The 73.4 and 300 GB model need a 4 cylinder filling partition until the 4 GiB border is reached. The rest is easy - if  I want to create larger partitions after the 4 GiB border, I just have to multiply the size by the cylinder value for 1 GiB. So there's no need for any size sliders or everything, and the partitions are always exact the same size.

When I first started using PFS a few years ago I really struggled with it.  Specifically, I had a hard time with some of the more technical documentation - needs a "PFS for dummies" guide.  ;)  But once I figured it out it's working great for me on both my main Amiga systems now, and I wouldn't use anything else.

Some tips:



Last, since I believe a picture is worth a thousand words, here's some screenshots from my system showing my settings.  Hope this helps!  :)

This is total BS, i have been using sfs since it practically came out and in all these years i have never had this happen. and its not one case, i use it across more than 20 different amigas. The problem is people either don't follow the instructions setting it up or use cheap/flakey cf's usually. Setting maxtransfer right is manditory especially in the case of a600/1200 ide etc.

the original Pfs3 used to have a bug that was well known and blew up under certain situations, which i believe is fixed in the latest ones.I think the author fixed it.

hdinsttools is known to cause rdb problems yet people insist on using it still.
It does something odd to the rdb, and if u come along and try to use hdtoolbox on it afterward it can cause problems.

Unfortunately SFS (AmigaOS version) has some bugs that cause self destruction sometimes. Ok, not self destruction but it corrupts itself and there are no repair tools. Only solution is taking a backup and reformatting partition and then copy back.

And of course remember 127GB size limit (in case you are using larger HDs).

Well funny with the load of machines i use, some run 24/7 i've not lost a single partition.. samsung ssd,sandisk cfs and regular drives, in 20 years of using it i have never had a partition loss caused by it, I have also sold many amigas pre-setup with it and talked at least a few hundred people thru setup and use in these years. I use drives from 50mb to 1TB,and yea i know of the 128gb partitions which is not a big deal.

SFSsalv works for sfs/00 partitions,not that i have ever used it.
I am not trying to sell anyone on it, i  just think i have put it to the test. Either i am incredibly lucky or the claims are unfounded.
I dont want to hijack the thread though.

When adding L:pfs_aio-handler to RDB, HDToolBox says version 18.0, but a version L:pfs_aio-handler says 18.5 - why?

By a slight error I used pfsformat on df0: instead of pf0:, with the result that df0: became unreadable of course, but no big deal. Bigger deal was that pfsformat then, since df0: was unreadable, decided to put Trashcan, Trashcan.info and a new Disk.info in my sys: instead. Well, wasn't that great.

I've used SFS for 10 years on my 060 A1200 with FastATAII, and it's been flawless.

If using PFS, you must use the pfs format tool like what Mike says. Read the instructions carefully, it's easy to use (I use PFS aio on my A600). It allows you to turn on or off long filenames and adjust the delete cache (.recycled hidden drawer on partition). SFS has the same, but '.deldir' IIRC. Hmm... Or is it the other way around? I only had 4 hours sleep last night, that's my excuse. :)

SFS is OK until you have a problem and it can fast become a nightmare. PFS3 doesn't have these problems do in that respect it's much better. The extra features and performance improvements are icing on the cake.

One thing I will say about PFS, is does it have a recovery tool should anything go wrong?  Not that I've ever had anything go wrong, but I did try to use the recovery tool that comes in the 53 archive once, and it said it didn't work with the latest version of AIO.  Thoughts?

The only time I've had to run pfsdoctor I used the MorphOS native version.  I don't recall any issues with it, though it was quite a while ago so my memory is very hazy.

After some years of no working Amiga I finally found time to check out my A500/A570 again. I'm now using the last version of PFS3AIO, and it works fine on the 68000. I've got some partitions in the 4095 MB, and a dummy partition with one block directly on the 4G border, so no partition can be across this area.

Actually I'm using about 6 GB, all partitions are formatted in PFS3AIO and shown in Kickstart 1.3 and 3.1. The rest of the drive is splitted in three partitions to 22 GB each. And this is the problem: I can format them in HDInstTools, the PFS window pops up and after a while the drive shows up. But after a reboot the 22 GB partitions are not existing, they're not even listed in assign devices. Is there a partition size limit in PFS? I'm actually using PFS\0. What is the difference between PFS3AIO and PFS3AIO-custom?

Another question is: How does Kickstart 1.3 handle the 4G-Border? I've copied a disk to a partition directly above the 4G-Border and it worked.

Other things: There is somewhere a patch that Workbench 3.1 shows large partition sizes. I haven't found it yet, is somebody using it? For Workbench 1.3 an enhancement existed, it provided nearly all functions of Workbench 2.0. But I don't remember the name anymore. Has anyone an idea what this could be?

Greets, RC.

This is a matter of the file system and not of the kickstart. However, as far as the FFS of Kick 1.3 is concerned: "Not at all". It will just self-destruct its partition.

Other things: There is somewhere a patch that Workbench 3.1 shows large partition sizes.
Yes, it's called Workbench 3.1.

If it wasn't clear, no partition is FFS 45.9 because it doesn't work in 1.3, and I don't wanted to use the original FFS.
So the question is exactly: Is it possible to use partitions formatted in PFS3AIO above the 4G border in Kickstart 1.3 ?

Workbench 3.1 shows in the window title only partitions sizes <4G correctly, larger partitions have an incorrect size.

That depends on the device the file system is mounted on. It is not the kickstart that limits the partition size, but the file system and the device it is mounted on.

Sorry, 3.9 fixes that. And 3.1.4 of course, too.

PFS3AIO checks whether the beginning and the end of the partition are accessible and refuses to mount if not. So if a partition shows up, you can safely use it.

Well... The problem is that the device might interpret the access modulo 4GB. Thus, while the first and the (seemingly) last block are accessible, they might not be what you expect.

I'd find it rather strange for a SCSI driver to "interpret" the input of a HD_SCSICMD request. This would mean that the driver calculates the offset from the block number only to convert it back into a block number to be sent over the SCSI bus. Quite an unnecessary set of calculations.

And for TD64 or NSD it would be a catastrophic programming failure to calculate the input modulo 4G because these commands are made for 64bit. But I doubt they are supported by the A570 anyway.
