hello there, i just want to ask what is the difference of having your IDE CD/DVD drive in /dev/sd0 rather than in /dev/hda? my friend and i have the same kernel version and distro (Ubuntu). the only difference is, my hard drive is detected in the file system of /dev/hda and his is in /dev/sd0. what do you think is the reason? thanks.

/dev/hdX is a PATA drive, /dev/sdY is a serial (SATA or SCSI) drive. My USB drive also comes up as an sdY even though the HD itself is PATA.

Most external USB drives and some laptop drives also come up as Sd as do some of the new SATA cdrom drives

... because they're serial drives... :icon_wink:

thanks guys! :)
