cyclic redundancy check

[monsieurjohn]

i'm trying to transfer some smallish files to my new computer, running on win2000, by floppy, because it doesn't have an internet connection yet

whenever i try to get a moderately sized file (really small files work fine) off the disk, it cranks for a while and then says there's a file transfer error - cyclic redundancy check

has anyone ever seen this, and does anyone know how to fix it? three different floppies did the same thing. plus i found a thing online where a guy had the same gripe, and it only happened on his NT machine. so i think that the OS is my problem, but there's got to be a way around it

anyone?

CRC errors are very common. Chances are that the file is corrupted in some way. What the CRC does is basically produce a checksum. If the data is corrupted in some way, the checksum doesn't match up and fails the cyclic redundancy check.

I would try putting the file in a zip archive, and put the zip file onto floppy. .zip compression has some slight protection against CRC errors, so that *might* help.

i don't see how the file could have gotten corrupted... i downloaded it and dumped it straight to a floppy. dang windows.

i'd try your suggestion that if i weren't trying to get winzip itself onto a new computer without an internet connection

i'll just wait until i can download it, i guess.

so is it just an NT thing? dang. i hope i don't have to deal with this forever.

thanks, though.

doesn't sound like a NT thing.. sounds like the connection between the floppy and motherboard isn't very um.. good.. old motherboard or old cable or old floppy drive.. or the ribbon cable's introducing random bits during longer transfers.. who knows..

 

[monsieurjohn]

small files transfer okay

and the motherboard, floppy drive, and cable are all brand spankin' new...

i checked connections early on.

could it be because i put the files on the disk with windows 98? (i'm shootin' in the dark now)

anyway, floppies are inefficient. i don't mind it being slow, but i'd love to be able to walk away and let stuff transfer. do you know how to hook up a serial cable to transfer files? i'm sure it's doable, but i don't want to set up a network or anything because i'm going to ditch the old computer as soon as i've harvested the useful stuff.

Yeah, it definitely could be that the floppy cable is bad. Does it happen with other files that you try to transfer over floppy?

mj> You would need a Laplink cable in order to set up a Direct Cable Connection link between 2 machines. However, that would also require installing some networking protocols.

Just because a cable is new doesn't necessarily mean that it works. There could be wire breaks inside the ribbon cable. Try a different cable if you can.

[monsieurjohn]

all right, i'll give it a shot with the floppy cable from my old computer, or maybe i've got another one around the house.

we'll see...

You can get those errors if the disk heads are out of alignment relative to each other.

You can get stuff like that if you write the disk with an imation superdrive that has very small heads.

There could be a small bad spot on the floppy.

But, this is one thing that you can't blame windows for CRC's have been around a long time.

 

[monsieurjohn]

new floppy cable didn't work, so hopefullytomorrow i'm getting a new floppy drive. i really should have one sitting around, but i can't seem to find it.

my compsci teacher thinks it's a problem with the logic in the floppy drive. he's probably right, since he's been around computers forever

anyway, we'll see if it works

MJ, here's an even faster way to yank those files off of your old computer. Just yank the hard drive out of the old computer, slap it into the new computer, temporarily (on the secondary master), and copy away. That's my harvesting method of choice when a network is not an option.

CRC's have been around forever. Like Dan said, it's used for helping to check if data is corrupt or not. I've seen CRC errors on floppy disks back in the DOS 4.0 days when I first started playing with computers. So it's definitely not an NT/2000 thing.

this morning i went to get a new floppy drive. i got home, popped it in, and it did the same thing.

so i started thinking: could it be a bad motherboard? if so, i'm not going to bother to fix it

well as it turns out nothign was wrong with it in the first place. i assumed that since it did the same thing with both floppies it had a universal problem. somehow i just got two floppies with the same error, so now everything's a-ok

and now i have a modem for my new computer (external usb modem, it's funny), so i'm on the soup for the first time with it. very exciting.

it's silly watching it load all these graphics for the first time

and jhowse: that's a good idea, i wonder why i didn't think of it. luckily now i don't have much to transfer anymore that i don't want backed up anyway, so i'll just move stuff on cds.

 

[meezercat]

Hmmm. I actually was getting a lot of these errors when trying to move mp3's from one folder to another. It happened when both folders were on the same hard drive, and still happened when the two folders were on different hard drives. No floppies involved whatsoever. It was annoying. So I finally just deleted the files and re-downloaded them.

 

[JHowse]

Hermie, that sounds like corrupt data on your HD. You did the right thing to fix it, though if you ran Scandisk and then Defragmenter, they would have probably fixed your problem.

MJ, CD's would work, too. Personally, I despise floppy drives. I only think they are useful for booting the computer when you don't have Windows installed on the drive, yet. It's always good to have a boot disk or three handy.

the macs at my school have done away with floppy drives, and as much as I think I don't use them, you start missing them when they're gone. I agree booting a machine after you (me) screws up windows and need to start from scratch, DOS and a diskette will keep you from tearing your hair out.

Not to mention that, without a network, the only practical way to move script files, or small Word documents from one system to another is floppy.

It takes, say, 10 seconds to put 500kb of files onto a floppy, but would take over 2 minutes to do on a CD-R or CD-RW because of the overhead needed to write the file system, do the burn, close the session, etc.
