Title: Disk defragmenter for 68k ?
Post by: Chrome on August 15, 2008, 09:42:39 PM: ReOrg 3.11 seems to have certain problems with OS3.9 and large partitions.

What is the best/working solution for defragmenting volumes under os3.9 ?

Post by: Lockon_15 on August 15, 2008, 10:06:02 PM: AFAIK, if you put SFS filesystem on your setup, you'll get a self-defragmenting system which can be additionaly forced to defragment.

Post by: Piru on August 15, 2008, 10:20:52 PM: SFS doesn't self defragment.

In fact SFS is probably the worst filesystem on amiga regarding fragmentation (if multiple apps are writing to files simultanously, each will get a block allocated in sequence, creating the worst case scenario fragmentation).

Post by: amigadave on August 15, 2008, 11:13:16 PM: I used to use a program called "BAD", and never had any problems with it, but I have read that it could create some really bad results for some people. I still have the original box and floppy, but it may be corrupted by now.

I also have some disk tools from Upper Design, but just reading the package it came in I see that it is for file recovery, not defragmentation.

I would think that there would be many PD defrag programs available.

What kind of problems are you having with ReOrg3.11?

Post by: Piru on August 15, 2008, 11:40:17 PM: ReOrg doesn't handle partitions beyond the 4GB area.

Some years ago I bought PFS3 but was never able to get it to work right. From what I heard at the time it was very good.

It was supposed to clean up after itself so to speak.

Post by: Chrome on August 16, 2008, 07:22:06 AM: QuarterbackTools has a working disk-optimizer, however it was even back then and now it seems to run partitions over 1GB forever. Also it has problems allready when it was released with 040`s copyback-mode; my 4000/040`s hd got scrambled few times in 1994 when I tested it.

I`m using FFS DC for my paritions; hd is 4GB (~3.7GB).

Yeah, but it have the best defragmentation program I see, hands down. And is working on partitions over the 4Gb barrier.

Post by: orange on August 16, 2008, 10:47:34 AM: IIRC, there is a small defrag util on aminet for PFS. it simply copies file or something.

You're the last person on Earth I'd argue over any Amiga issue.
:-D

Seriously, I read somewhere about that "defrag in background". Is it really a fake or it's just a bugger on high-end setups with concurrent write ops ?

I thought SFS would be safe bet for my A500/A530 1Gb CF setup, since FFS validation takes too much time.
Any suggestion?

Thnx

fake

about SFS (latest versions) on an A500 ... do you have a 020 with kickstart 3.0 at least?

Post by: Framiga on August 16, 2008, 12:51:37 PM: perfect then!

Take an eye to the fragmentation from time to time with the tool in the archive SFSCheck

SFSCheck partitioname: FRAGLIST

If you'l see files with a lot of fragments, run SFSDefrag

Use 512 Bytes blocksize and as much dosbuffers as you can (accordingly with your amount of fastram installed ... minimum 400 anyway)

There another tool (setcache) to fine tuning the read ahead cache (for better performances)

Good luck!

http://strohmayer.org/sfs/ (use the whole archive for the tools/docs and download the 1.279 as executable)

edit- to check the fragmentation, you will need a more uptodate SFSCheck version (2.43 68K) but i can't find the URL anymore.

that one is for Morphos. I have here the v 2.43 for 68K (same author) but i can't remember how i have got it :-)
Title: Re: Disk defragmenter for 68k ?
Post by: Flashlab on August 16, 2008, 03:00:01 PM: In the full SFS package several tools are included including the defrag tool. Maybe you found SFScheck in there as well?
Title: Re: Disk defragmenter for 68k ?
Post by: Framiga on August 16, 2008, 03:06:53 PM: that SFSCheck version is from Morgoth (a MOS guy).

The one bundled in the SFS archive, doesn't have the FRAGLIST option (v. 1.3)

Post by: klx300r on August 16, 2008, 04:45:44 PM: i would try 'quarterback' as it had a great defragmenter as prt of its tools package back in the day...used it many a times to save a bad disk :-)
