A 48 meg drive, can read from it all day but writes (usually between partitions, but not always) lock the drive up a lot. I have found that workbench itself does not lock up, but the hard drive does. IE I can still open ram: and my floppies from WB, but if I try DH0 or DH1, workbench wait for the drive to reply and blocks. I also have called Expansion on this, and they sugg. grounding my pals and I did but it did no good. If there are others out there with this problem, lets get talking about it and maybe the publicity will force Expansion Tech. to do something about this. Douglas G.

Tech, I had an Amiga 1000. I was having the same problems then as I have now. I called them several times, and they told me it was poor grounding of my PALs. My salesmen (who's name I will look for) sent me a letter describing how to ground my PALs. Before attempting this, I returned my interface for a new one. The same problems occured. I then "grounded my PALs." Same ol' problems. It was at this point that I realized the drive functioned perfectly when I used only one partition. Too late though. My 1000 died. I traded it in for an Amiga500 (I lost my favorite computer) and got a new interface from Exp. Tech. for the 500. Guess what ??? Same problems again. At this point I said, "%^&$ it. I'll only mount one partition for now." I think Exp. Tech. should look into this problem. Is it their driver? Is it their interface? Thomas A. Mikalsen "Dig me ... But don't bury me."

There have been a few posts about a bug which causes Expansion Tech's Escort SCSI drives to lock up at times. As far as I can tell, this only happens with the Fast File System when writing to the drive from one partition to another (i.e.: copying from one partition to another). The fix for this is very simple: change the priority of the harddisk.device from 5 to 20. I don't claim to be a filesystem expert, so maybe somebody could tell me (1) why this works and (2) if there are any problems doing this. I had my system working this way (A500) for nearly a year without any problems. Also, to anyone that's interested, I wrote a small program to change the priority of a task based on it's name. THis allows your system to boot up everytime with the correct priority for the device (if you put it in your startup-sequence, that is). ------------------------------------------------------------------------------ Dan Cogswell ph: (313)625-3234 (home-me work?)
