Hello,
So I was creating a archlinux usb bootable drive:
[root@masterkorp-laptop Downloads]# dd bs=4M if=archlinux-2013.06.01-dual.iso of=/dev/sdb 130+1 records in 130+1 records out 548405248 bytes (548 MB) copied, 0.964976 s, 568 MB/s
I was like WOW, this was too fast! But nothing ever gets written to the pen drive. To add to the weird factor, a dd to dev/sdb1 (partition) works as it should, slowly. But then ofcourse the iso gets unbootable.
The md5sum on the iso is correct. I tried with diferent pen drives.
Please, any suggestions is welcome.
I've been having this sort of problems with removable storage lately (copying multiple GBs of songs in a few seconds, except not really). The workaround I found out is to run the sync command after copying. That could take some time as all your data is being actually written to disk. I believe this is related to the write cache, please let me know if you find a better solution to this. -- Pedro Emílio Machado de Brito Engenharia de Computação 2012 - Unicamp Coordenador Tecnológico - Centro Acadêmico da Computação (CACo) (34) 9673-0963 - Facebook/Skype: pedroembrito - Github: pemb 18hxPDGcNDpsYYKJ2aghSh3mm9n3c4C7pf "Repair what you can — but when you must fail, fail noisily and as soon as possible." · Eric S.
