Copying drives

04-24-2009, 08:54 PM

According to one post, the speed of the copying can be greatly increased by enabling 32-bit I/O and DMA on the IDE drives, by issuing the command: hdparm -c1 -d1 /dev/hdx, for each drive.

If you use the "dd if=/dev/hdx of=/dev/hdx bs=1024" command how would you add the hdparm command?

Just run hdparm command(s) before the dd. It just changes a setting.

Been here a long time . . .

Do I issue the command for the Tivo original and the duplicate or just one time for both drives before the dd command on a separate line before the dd? Like:

hdparm -c1 -d1 /dev/hdc
hdparm -c1 -d1 /dev/hda
dd if=/dev/hdx of=/dev/hdx bs=1024

(This assumes the Tivo original is secondary master and dupicate is a primary master)
