FTP corruption for large files

[popal]

Hey,

When I transfer files to my hard-modded xbox using ftp, large files (over 40-200 MB) seem to get corrupted most of the time, and I have to re-transfer them several times until they match the original files. I check this by uploading the files to the xbox and re-downloading them then doing a hash check, however this process is very bothering and sometimes some files just plain refuse to get transferred correctly.
However the files don't get corrupted much because the games still play fine. At least, I haven't noticed any problem in any game yet except in one game which is Forza Motorsport (It gives me the disc dirty or damaged error).

I tried several FTP clients (FlashFXP, FileZilla, SmartFTP, Windows File Explorer), all have the same problem, and I get different hashes for transferred large files.
Any idea what could be causing this and how to fix this? The router and ethernet cables I'm using work fine for internet and file sharing.

I can only think of two things.
Your Xbox harddrive dying or you're using shitting cables.
Or the RAM/HDD in your PC/laptop is dying but I doubt it.

I don't think it's the Xbox HDD, it loads games pretty fast and never hiccups.
Anyway I tried 2 routers, 3 Ethernet cables, several dashboards, all combinations I tried give me problems.
There was a 290 MB file that never transferred correctly, it only did transfer correctly when I set the transfer speed as low as 50 KB/s. But that transfer speed is really really slow. Does this ring any bells to anyone?

I never had problems with FTP.
The only things I can think of is your Xbox drive dying and or using shitty cables.

Try replacing the drive for another drive.
Perhaps a more modern SATA drive with a Kingwin SATA>IDE bridge?

For the record, I was wrong in saying I didn't experience any hiccups in my hard drive. I remembered now that every now and then games would freeze especially during movies (I think they're called FMVs?).
Anyway you were right DinohScene, the problem was the hard drive. Today I got a new IDE hard drive and I installed it, and it works good! The files are transmitted correctly back and forth through FTP.
