md5sum of large files gives different results sometimes
- by Emanuele
I have an AMD quad core, 8 gb RAM, 1 SSD EXT2 (2 months old), 2 HDD EXT4, approximately 1 year old.
I'm using Ubuntu 10.04 x86-64 and when I compute the md5sum of large files (9 GB) sometimes I get different values than the one stored on a reference file.
Upon restarting and switching off the PC then I get the expected results no matter how many times I repeat it. But this is random.
I've turn on ECC (the fastest possible settings) and the issue seems to be rarer, but I've run memtest86+ for 6+ hours without a glitch (and with ECC off!).
Any idea? Should I update the BIOS of my motherboard (Asus EVO-something...don't remember it now)?
I've tried all the rest apart this, but genuinely don't know what to do anymore...
Any suggestion is appreciated!
