Since there has been a bit of discussion recently regarding Supra disks, I thought I'd see if anyone out there in netland has any suggestions about fixing this problem. COMPONENTS: Amiga 1000 w/2M external RAM(ASDG mini-rack), Supra host adaptor, ST-251 disk and Adaptec 4000A controller in a suplus enclosure. System is being run in Europe with a step-down transformer and is an NTSC unit. Current software is 5.1a but problem was identical with 4.X as well. Am using FFS but again problem was identical with SFS. PROBLEM - When delivered, disk showed 10 bad blocks. Running supraformat in the "map on" mode discovers nine but when supraformat tries to write the bad block data out to the disk it puts up a requester saying "Cannot Format this harddisk". The format went without problems up to that time and works ok if "map off" mode is used. I managed to partition my disk so that the first partition has zero bad blocks but the other two have the rest. I have tried the Adaptec on other disks and had it checked where I bought it. I also tried the Supra host adaptor on another system and it worked ok there. If anyone has a fix or even an explanation of what is going on, I would love to hear it. I have verified that the Adaptec configuration is right and there isn't much else to try. Also, does anyone know what the weird numbers that supraformat puts out when it is invoked? Mine puts out something like 20 0 0 0 but when you do a format with the "map on" option, it puts out LOTS of lines sorta like that one. Anybody from CMI or Supra want to tell us about this one? Unless you think this is of general interest, just email me your suggestions and I'll summarize. Thanks a million {sun,hplabs}!sytek!syteke!jim -- Jim Sanchez Sytek Brussels

Well, I've seen a similar problem with an ST-4096/Adaptec combo. ,I don't know for sure what the problem is, but I can maybe help a little bit with the codes you're seeing. (I'm suprised that a version got out with the debug still in...) I believe thet codes you're seeing is the SCSI sense results. If you grab an Adaptec manual, it'll have the info in it that tells what each one means. I can't help you with any specifics right now, I don't have an Adaptec manual here at home. You might give Supra a call and ask them... They're working on some new software, but I don't know for sure what enhancements/bug fixes they plan to incorporate. : : Thanks a million : {sun,hplabs}!sytek!syteke!jim : : -- : Jim Sanchez : Sytek Brussels -- -Bill Seymour ...tektronix!reed!percival!agora!billsey ...tektronix!sequent!blowpig!billsey Creative Microsystems Northwest Amiga Group At Home Sometimes (503) 684-9300 (503) 656-7393 BBS (503) 640-0842
