I have a 20mb HD on my 1040st with an ICD SCSI adapter and a omti controller tying it all together. One of my partitions (10mb) is just about full, and write times to it are horrifying! We're talking a minimum of 7-10sec per file where the drive doesn't appear to be doing anything, then the red light will flash, and on to the next file. The mostly empty partition on the drive still responds just as fast as you would expect... I thought it must be a fragementation-type problem, and lacking anything like the defraggers available for the PC, I backed up all my files to floppy with Turtle, restored them, and looked forward to a performace increase. Nope. What's going on here? Any help would be appreciated. Also, is there a PD program to complement Turtle? I mean something that restores to your HD and just prompts you for each disk. That would be a lot easier (and faster!) than copying them from the desktop.... Thanks in advance, Brian Daniels (cs63bld@unccvax.uucp)

There exists "UnTurtle," (named with permission of George Woodside) which allows you to do restores semi-painlessly. You pick a floppy drive to restore from and a partition to restore to...then hit return. When all files are copied, insert the next disk and hit return. UnTurtle handles all of the folder creation and so on. UnTurtle is up to version 1.3 and I've been using it with no problems for years. Version 2.0 is supposedly on the way (rewritten from Personal Pascal to Laser C, and with a nicer user-interface), but the author has other, more pressing projects to finish first. In keeping with the Turtle idea, UnTurtle is freeware. If it isn't up on Terminator, I'll post it tonight. Jeff |Jeffrey C.

Used to be that the FAT was searched from the beginning every time a new cluster was needed. The fuller your partition, the bigger the FAT and the slower the write. Fix: Keep your partitions small or get TOS 1.4. >Also, is there a PD program to complement Turtle? I mean something that >restores to your HD and just prompts you for each disk.

It is easier to use and more flexible than Turtle and comes with a companion restore program, The Key. -- ================================================== | Michael Fischer <fischer-michael@cs.yale.edu> | ==================================================

S L O W was a real TOS 1.1 problem. TOS 1.4 fixed it. The problem is in writing, and the wrong algorithms used in TOS1.1 to access the FAT to find a block to write into. 2. There is a PD program called restore that quickly restores the disk from a turtle backup. Works real good! Howard C. Johnson ATT Bell Labs att!lzsc!hcj hcj@lzsc.att.com

You either need FATSPEED or TOS 1.4 , or the latest version of the ICD utilities
Any of these will sort out this problem.

I think You dont't have TOS 1.4. Before TOS writes a new file, it searches from the beginning of the partition for the first free cluster and in the older TOS that needs that time. In TOS 1.4 that is much faster, so it doesnt bother. When I had the older TOS, I made me a program, that worked interactively and could find all files that lie in the first 256k and then shift them to another place on the partition. If the beginning of the partition is free, writing new files is very much faster. For first help You can save all files to another Partition or archive, free that partition, write a file as filler to that partition, restore the partition and then delete the filler. Regards j.k.

This is the chief user-visible improvement in TOS 1.4 over previous TOSes. Another of the improvements will help, too: adding enough memory to the sector cache (with CACHEnnn, for example) to hold all the FAT and root directory sectors on all your disks. That way your disk won't constantly be reading the same stuff (the FATs) for every file: it'll already be in memory. ============================================ Opinions expressed above do not necessarily -- Allan Pratt, Atari Corp. reflect those of Atari Corp. or anyone else. ...ames!atari!apratt
