I have a IIGS rom 01 with 1 3.5 disk drive, and 1.25 MB of ram. I also have a 5.25 disk drive, joystick, system saver IIGS, Datalink 2400 and a Hyperstudio audio digitalizer. My problems: 1> Recently my 3.5 drive has made some whistling sounds when it runs...Not very loud..but consitant...sounds like somethings hitting something or wearing it down....It only does it when the drive is being used....Is it normal, or should I have it checked out? No damage has happened with it so far..... 2> I'm using Proterm to call our Vax 8600 here. I can't get Zmodem to work...I can send files just fine, but when I try to receve files, the result is a file with Control j's insted of Returns. I can't seem to change (correct) the problem with options. Any Ideas? TSEMM@Alaksa.BITNET TSEMM@Acad3.fai.alaska.edu

I usually ignore it, unless it's an important data disk and I suspect the disk is wearing down. I don't know if it's the same phenomena you are experiencing. >2> I'm using Proterm to call our Vax 8600 here.

I can't seem to change >(correct) the problem with options. Any Ideas? Unix systems use the linefeed (control-J) for line termination instead of carriage return (control-M). I assume you are sending text files. I transfer text files by dumping them to the screen and capturing/logging the text to a file. ProTERM has a gawdawful huge scrollback buffer you can use. The benefits? It's at least as fast as Zmodem, and you don't have to convert ^J to ^M first. I send text files by mailing to myself, and sending ASCII from a file. Works great. It's prone to line noise at times, but with text files it isn't too critical. -- Dave Seah | Omnidyne Systems-M | INET: seah@ee.rochester.edu ^..^ | "User-Friendly Killing Machines" | America Online: AFC DaveS yargh! +----------------------------------------------------------------=*

Happens to me, too. Usually only on the outer tracks of the disk, so all file operations cause it as they read/write directory info. When I have this happen I usually relegate the particular disk in question to backup status just because the whining is annoying. It happens mostly for me with some 3M disks and one batch of bulk disks (but oddly enough I have never had whining with two other batches of bulk disks. I have found out that that whining and the other noises coming from this disk drive (which I was very impressed with at first because it was so quiet) can be subdued a bit by placing a paperback book or something similar under it. When I moved the computer I moved the drive from a very sturdy desk to the top of my modem sitting on a table and the combination acts like a sounding box for the thing.

I don't think you understand the problem... It is doing it with *EVERY* disk that is run..even when it runs without a disk for that 1/4 second or so...... It isn't just a disk......I know about that. Um...it is actually more of a squeeking sound.....kinda a real muffled sould that happens when you "pop" a car into gear......I'm trying to describe it...but.... you know the problems......

There are several possible causes of this, for example oxide accumulated in the pressure pad. Try using a disk drive cleaner. The vibration cannot be good for the R/W head. >2> I'm using Proterm to call our Vax 8600 here.

I can't seem to change >(correct) the problem with options. Any Ideas? I use a different set of file transfer programs, and UMODEM protocol; however, I have similar problems -- the UNIX "umodem" program does not insert line delimiters in receive-text mode, so I have to use binary mode, but since Apple II text file line delimiters are normally CRs while UNIX convention is LF, some translation must be done. I wrote a pair of transfer-archive utilities (in C) that I use on both ends to facilitate transfer of batches of text files via the binary mode; if you can use these, drop me a note. The alternative is to translate the LFs to CRs and vice-versa on one end or the other, using whatever utilities are available (on UNIX, "tr"; on GS/OS, Glen Bredon's "FIXER").
