Bad HD?

Hello!

Is this right?

[root@claudia gu]# hdparm -tT /dev/sda

/dev/sda:
 Timing cached reads:   2812 MB in  2.00 seconds = 1405.29 MB/sec
 Timing buffered disk reads:  150 MB in  3.01 seconds =  49.88 MB/sec
[root@claudia gu]# hdparm -tT /dev/hda

/dev/hda:
 Timing cached reads:   2928 MB in  2.00 seconds = 1464.45 MB/sec
 Timing buffered disk reads:  166 MB in  3.01 seconds =  55.22 MB/sec

The SATA disk shoudn't be faster?

Look at this:

[root@claudia gu]# hdparm -i /dev/hda

/dev/hda:

My arch install is in the SATA drive and I'm a bit worried. Partition magic says that this disc has wrong geometry or something and can't handle its partitions.

Thanks,

Gustavo

Re: Bad HD?

hdparm's functionality on SATA drives is rather limited IIRC.

The speed of the PATA drive does strike me as very odd though. As does hdparm not showing the UDMA setting properly.

Re: Bad HD?

IIRC Partition Magic cannot handle ReiserFS, I would not be too worried about that.
