I got MSH from an FTP site the other day, and followed all of the discussion here about it. Thankfully, on the first try, it worked like a charm. (Thanks c.s.a. posters!) There is a problem with MSH, however, that I'm curious about. I formatted a brand new disk using MessyFmt accepting all the defaults, etc. I copied files to and from it, and it was fine. When I tried to use the files on a PS/2 Model 50, it worked fine... until I tried to delete some files. Then MS-DOS gave me a "Bad FAT" error. I formatted a different disk on a different Model 50, and it worked fine. I put some files onto it, then went to my Amiga. When I tried to read some files off of it, MessyDOS gave me a disk error. I don't know if these problems are related or not, but has anybody else encountered something like this? (I don't have DOS-2-DOS or CrossDOS to try with them.) And a related problem deals with ASCII conversion. An AmigaDOS ASCII file (each line ended by hitting RETURN) when sent to MS-DOS, the CR's have all changed to LF's. Is there a quickie program to get around this? +------///-+------------------| BRETT KESSLER |------------------+-\\\------+ | /// | consp11@bingvaxu.cc.binghamton.edu | \\\ | | \\\/// | consp11@bingvaxa.BITNET | \\\/// | | \XX/ | (PeopleLink) B.KESSLER | \XX/ | +----------+-----------------------------------------------------+----------+

I used messyfmt to format a disk, and Dos2Dos gave me a "read" error with the disk. BUT I had no problem reading, writing, or deleting files from that disk on an AT clone. Nor did MessyDos give me an error when I used the new files from the clone. > And a related problem deals with ASCII conversion.

It depends on which machine and which software package you are using. In general (and I will probably get hit for this) end-of-line is LF on the Amiga (even though you depress a key labeled RETURN) and end-of-line is CR+LF with MS-DOS. In any case, you need a couple of utilities to add and strip CRs from files. There are many. I use Matt Dillon's 'addcr' and 'remcr' which are available on Fish 168/169. One disk contains the executables, I can't remember which.

A side note on MSDOS disks on the Amiga. Most high density (e.g. 1.44MB) floppy drives are *not* guarenteed to write reliably to 720K disks that will later be read on older, non-high density drives. This could be one cause of problems people have going from the PC back to the Amiga. In my experience, the low density drive can read the file written on the hd drive 95% of the time, but it can still fail. When I have a time constraint, I make two copies on two different disks.

Does this mean that a regular density disk (ie: DS/DD) written on a high density drive will get read/write errors more frequently than those written on a regular density drive? Or am I misunderstanding the above message? And if I _am_ understanding it correctly, is there any reason for it? +-------///--------------------| BRETT KESSLER |--------------------\\\-------+ | /// E-Mail to: consp11@bingvaxu.cc.binghamton.edu \\\ | | /// or try: consp11@bingsuns.pod.binghamton.edu \\\ | | \\\/// and to: consp11@bingvaxa.BITNET \\\/// | | \XX/ or on PeopleLink: B.KESSLER \XX/ | +-----------------------------------------------------------------------------+

Or am I Nearly right. It will get more r/w errors when used in a regular drive. It should work fine in a high density drive. The reason I've been told is that the high density drives lay down a narrower, more precisely positioned pattern of magnetic signals, and the lower density drives are sometimes not sensitive enough or aligned accurately enough to pick them up. Look in an official IBM Msdos manual, version 3.30, to see the official warning. See the FORMAT command. lee

To further this confusing issue...my experience with this problem (going between 1.44M and 720K drives) has been that disks fomatted to 720K in the 1.44M drive have never failed when read in a different 720K drive. The reverse (formatting with the 720K drive) has been much more problematic. I've seen this problem both with going from PC to PC and PC to Amiga. I qualify this with saying that I haven't gotten MSH up and running yet. Of course, your mileage may vary. -- Tim Costello Du Pont Medical Products ...!uunet!eplrx7!costello -- The UUCP Mailer

What the problem most likely x%is that the High Density drive has a narrower head, and so it writes a narrower track on the disk, even when writing a 720K diskette. So when you take the 720K disk written in a HD drive and try to read it in a normal 720K drive, you have a wider head trying to read the data off of a narrower track than it is used to, and it may get errors. -- John Sparks | D.I.S.K. 24hrs 1200bps.
