right on I'll check that out. the problem seems to be fixed though, changing topic to solved, thanks for everyone's input.

the cables I have are cat6 from monoprice.com I went and got a trendnet nic. Not sure how good they are but was just trying to get something to try out. I also bought new cables (cat6) just in case those were the problem. I am not quite ready to say the problem is solved, because I thought it was last night and it wasn't... but so far so good. I didn't replace the cables, I simply replaced the nic, and now things seem to work. So if it WAS the nic, it was 2 nics, because I had already tried replacing it with the same model. So 2 Intel nics were doing the exact same thing? just seems so unlikely that its a hardware issue to me in that case. Could the driver for it become corrupted somehow? I dunnno, but I'll keep testing to make sure its solved and come back and update.

I've replaced the cable a few times and the nic. Though the nic I replaced was the same model. I will go and and buy a new nic, and maybe some new cat5 cables and hopefully it will help.

sigh. i spoke too soon. I guess I didn't run enough tests last night. I am still seeing this issue, even without the 2 switches I thought were the problem connected. I hooked just the unraid computer and my win7 box up to an old 10/100 belkin router. Last night I was able to copy files without errors, but I only tested about 20 files. Today, with the same set up, I am getting errors again. So I tried the suggestion above, I hooked up my wifes computer to the router, and tried copying about 50 files from a share on MY win7 computer. They all transfered fine. So I'm back to thinking that this is an issue with the unraid box. What more can I try to narrow down the issue?

ok at this point it seems to be the switch. both switches in fact. I use my old router, no problems. i attach 1 switch to it, get the error. I attach the other switch to it, also get the error. both switches are ASUS GX-D1081/G. Anybody recommend a good switch? I need 2 it seems. Thanks for the help guys!

Well, I had thought it might be my switch. SO I had replaced my switch with another one, but again it was the same exact model that I use downstairs (an ASUS). I had a thought, and I used WinSCP to scp the files instead of using windows/samba. Sure enough, when I copied files FROM the server, I got the following error, about 1 minute into the transfer: Incorrect MAC received. If I transfered files TO the box, no errors. I tried this several times, and had the same issue. Now before, when I tried a different switch, I still had the switch connected to my router downstairs (also an ASUS, running a version of Tomato firmware). This time, I went into storage and got an old Belkin router out and tried it. BINGO. files transferred fine with no errors. SOOO, it's either BOTH switches, OR, my router. I'm leaning towards my router, but I'll go test to see. My next question is, could it be a cable? I mean, I replaced the cables between the unraid box and the switch, and my win7 box and the switch. I assumed (I am not a network guy) that when it routed those were the only cables involved. Can a bad cable between my router and switch cause this? I can temporarily bring my router up and use a diff cable and see if there is still an issue. Anyways thanks for the help, and I'll come back and post my findings and change the topic to SOLVED. so glad I was finally able to narrow it down, was driving me nuts

thanks for the reply. I should have included this. I had some issues with my onboard nic on that board, so I went ahead and bought this: Intel PWLA8391GT 10/ 100/ 1000Mbps PCI Desktop Adapter PRO/1000 GT - OEM I also bought one for my windows 7 desktop, not for any real reason other than consistency. So two things I have tried is to take out the intel nic in my windows 7 computer and use it's onboard nic, and then replace the intel nic in my unraid box with the intel nic from my windows 7 box. Neither worked. I have copied a file from windows 7 to the unraid box and checked it on the unraid box, and no errors. I have done this with about 50 files, and no errors. If I copy 50 files FROM the box, I have the errors. Also, I tried copying from the unraid to my wifes windows 7 box, and to my macbook. I see errors on both those boxes. So I don't *think* it is an issue with those boxes. Also since I replaced the nic, it doesn't seem like it'd be a hardware issue, especially since it's only when I copy from the box. It leads me to believe it's a software issue, but where exactly I don't know. And I didn't see anything that would indicate that in the syslog, but I'll admit I don't understand a lot of it really. I don't know that this hasn't been an issue from the time I built the box, because i never thought to do any crc checks on files I copied from the box.

I discovered something strange going on with my unraid server this week, and I'm completely lost on what it could be. It started when I had copied a couple of directories of FLAC files from my unRAID server to my desktop (windows 7 64) so that I could convert them to mp3. I used dbpoweramp to convert the files, and I was getting errors. After some research, I downloaded the tool AudioTester and tested the flac files. About half of the files had FRAME_CRC_MISMATCH or SYNC errors. Uh oh, I thought. So I tested some other unRAID flac files, and more errors. At this point I was very worried that I was going to have to re-rip all of my music. I then ran AudioTester on a different computer (a different windows 7 64 computer) and got errors in my FLAC files. I then got on my macbook, and ran a similar tool (xAct) and also was seeing errors. So finally, I noticed something. I tested the same folder of FLAC files on different computers. Both had errors, but the errors were not the same. Different files and different positions in the file were throwing the FRAME_CRC_MISMATCH error. So I used one folder of FLAC files, ssh'd into my unraid box, installed FLAC directly on it and ran flac -t on the folder that was giving me errors. Low and behold, all of the files passed. So I copied a couple folders from my windows box that I had tested and had no errors to the unraid box, tested them on the unraid box, and no errors. I copied about 10 folders over, and none of them had errors. ok so at this point, I have a problem with any outgoing file from my unraid box it seems. so what can cause that? I have tried the following: ran memtest. 15 passes, no errors. replaced the switch and cables between both my unraid box and my windows 7 box replaced the nic in my unraid box (albeit with the same brand nic, but it was my only extra) I was running 4.7, so I upgraded to 5b14 with no change ran parity check, it ran fine I ran smart tests (short) on all the drives. I did find 2 errors in my parity disk, so I replaced the sATA cord. and the errors didn't happen all the time that I was getting crc copy errors. So I'm lost as to where to go from here. I ran the memtest last night. I've attached a syslog and smart reports on all my drives.
