OK thanks for everyone would offered advice on this subject. I've done it! Here's how: My set up: Performa 5200 PPC and a D2 Jaz drive 1Gig You should already be running OS 8. Back up all your stuff onto a separate drive (I used my Jaz) and check it is OK. Restart with unnecessary extensions off (normal procedure). Run the OS 8.1 updater. Restart. Check it all works and you haven't lost anything. Be sure. Click the icon for your back up drive and select ERASE DISK from the SPECIAL menu; when prompted select Mac OS Extended in the pop up. Click ERASE. (Not all drives will work). When it is done, back-up your updated OS 8.1 main drive onto it. Check it's all OK, (be sure!). Restart, using the back-up as the start up disk. Check it's all OK, (be sure!). Click your original drive icon and select ERASE disk from the SPECIAL menu; when prompted select Mac OS Extended in the pop up (Partitions can be selected at this stage - click CUSTOM: Essential if you are running on 68040 or similar. 68040 will require the start up partition to be Mac OS Standard Format, the other(s) can be any format). Click ERASE. (Not all drives are supported / will work). If successful you can now transfer your backed up files to your hard drive. Restart and check. NOTE. It worked for me. It might not for you. I did save loads of drive space and I now have only one partition on a 3.2 Gig Seagate hard disk. The only problems so far are lost Aliases and it lost my User Profile in Netscape which I have successfully restored from my back up.

When someone gets a disk repair app out for HFS+ then I'll do the rest of my disks. Got back about 18Mb from the 500Mb drive. There's another little app out there (I think it's freeware) called MacSlack which will work out for you how much space you can save by going to HFS+, worth running it to see if there's much point to changing file systems. Gordon One of these days I'm going to think of a decent sig line

I've used PlusMaker and can only get 1K blocks - the same as the standad Mac tools give. I'm using a 5320 with a 1.2GB disk partitioned into 4 equal chunks of around 303Mb.

There's no point in making the blocks any smaller: it'll double the amount of disk access you have to do without saving a significant amount of disk space.

According to the manual that came with Plusmaker it automatically gives you 0.5k blocks, I can't remember for sure what size the blocks are on my external drive, but checking with MacSlack it would appear to have done 0.5k blocks. Just checked with Norton, yes 512byte blocks. Curious. Gordon One of these days I'm going to think of a decent sig line

Curious. > Well, after consulting Alsoft, it seems I was interpeting the 'Get Info' dialogue box too literally - it always rounds up to the nearest K. After experimenting with very small files in a temporary folder, I have now come to the conclusion that it really does create 0.5K blocks. I trust I haven't put anyone off using the tool!
