What's wrong with having drives named as /dev/sdX ? Historically SCSI drives were named /dev/sdX, while IDE /dev/hdX. Since some time ago any hard drive is named /dev/sdX regardless whether its IDE/ATA, IDE/SATA or SCSI, there is one uniform interface. > l...@home:~$ sudo hdparm -c1 /dev/sda > > /dev/sda: > setting 32-bit IO_support flag to 1 > HDIO_SET_32BIT failed: Invalid argument > IO_support = 0 (default) > > Mind that hdparm is a tool which was tailored towards IDE drives only. It is compatible with old interface (/dev/hdX) but only partially with the new one (/dev/sdX). > So, is there anything I need to do to make my system change the drives from /dev/sdX to /dev/hdX?

How can I verify which is in use right now? dmesg will give you all the information you need. It displays kernel messages (additionally they go to /var/log directory). So you can open a terminal and try: dmesg | less to browse through all the messages. If you want to find out what mode the hard drive is switched to search (to search press /) for lines starting with: ata1 (for the 1st controller) or ata2 (second). In my case I have [ 0.517229] ata1.00: ATA-7: Maxtor 6L200P0, BAH41G10, max UDMA/133 ... a few more lines here [ 0.572323] ata1.01: ATA-6: WDC WD1200JB-00GVA0, 08.02D08, max UDMA/100 ... a few more lines here [ 0.572362] ata1.00: configured for UDMA/133 [ 0.572365] ata1.01: configured for UDMA/100 Which says what respective DMA modes are enabled for my hard drives. > Also, if any updates happen, with they wipe out this change I am trying > to make?

However, Preload does not do much from my experience but it might depend on how much memory you have and how fast the disk(s) is(are). -- [HARDY-LUCID] No DMA nor 32bits IO support https://bugs.launchpad.net/bugs/228302 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
