Hi List;
I have FC5 on an IBM Thinkpad Z60m with 2G of RAM and a 100G SATA HD. I also
have a removeable CD/DVD drive and I can insert a HD adapter into
the "ultrabay" which adds a second HD attached to the main bus (as the CD/DVD
would be).
I inserted the second 100G ATA HD into the ultrabay and booted into single
user mode. The second HD shows up as /dev/hdc my main HD shows up
as /dev/sda. (Note if I boot with hdc=noprobe into single user mode then the
system is not aware of the root user)
I run this:
dd if=/dev/sda of=/dev/hdc bs=64K &
pid=$!
Note: I've tried the same with bs=128K, bs=1M, bs=256K and with no bs tag at
all with the same results
Then I check the progress from time to time with this:
kill -USR1 $pid
I find that my avg speed in 1.7m/sec which leads to a full backup time of
around 16-17 hours.
Before the deal with M$ I used to run SuSE 10 and was able to do a dd on the
same laptop inside of 4 hours.
Any help would be much appreciated....
Thanks in advance

It sounds like DMA is disabled.

How can I enable DMA on a SATA drive in a laptop?
It should be enabled by default. You could just boot with a Knoppix
CD and then specify the dma parameter at boot time to dd the disk.

How can I enable DMA on a SATA drive in a laptop?
hdparm -d1 <device>
I'd advise you take a look in the logs for any reported hard disk
errors. Last time I had a disk that was getting DMA turned off, I found
it was because of end-of-life related errors. May be time to replace
your disk.

hdparm -d1 <device>
I've yet to run across any SATA controllers which allow one to enable
or disable DMA support via hdparm.

Hi List;
I've followed these instructions to get my slow second drive issue fixed. It
seems to have worked. However now I can only mount the cd/dvd (with the dvd
drive in the 'ultrabay' as root by explicitly mounting the drive. My KDE
automount prompt no longer appears, etc...
Thanks in advance

I've yet to run across any SATA controllers which allow one to enable
or disable DMA support via hdparm.
The SATA drivers always enable DMA when possible. A dmesg is really
needed to see what is going on.

Should I grep for something specific or just attach an output after a bootup
of dmesg?

No offense intended & not related to the problem you have. The above
statement is directly related to the "Getting people into Linux" thread.
Statements such as the above is a major obstacle I have in getting
people to try Linux. Common complaint from potential Linux converts is,
way too much negativity/bashing between users of different Linux
distros. None of this nonsense with Windows so, why bother to switch?
Anyone else here run into this?
Any help would be much appreciated....
