Slow transfer rates in a Thinkpad R52
Hello: I have a Lenovo/IBM Thinkpad R52. It is a Celeron 1.4 Ghz, 256 RAM, Intel 915 video, sata hdd 40 GB, DVD-CDRW, etc. The thing, is that when I transfer files from the/to the CDrom, the whole system (even the mouse) gets really slow. This is the model of my sata controller reporte by lspci: Intel Corporation 82801FBM (ICH6M) SATA Controller (rev 03) Another thing, is that the hdparm program, can''t change the UDMA settings. It says that my drives doesn''t have udma, but it really has. [root@localhost ~]# hdparm -c /dev/sda /dev/sda: IO_support = 0 (default 16-bit) [root@localhost ~]# hdparm -c1 /dev/sda /dev/sda: setting 32-bit IO_support flag to 1 HDIO_SET_32BIT failed: Invalid argument IO_support = 0 (default 16-bit) Also, when the system start using swap, it start to slow (a lot, but not as much as when I read/write from/to the CDrom). This is the list of the modules I found relevant from lsmod: i2c_i801 11853 0 i2c_core 25537 2 i2c_ec,i2c_i801 ide_cd 42337 2 cdrom 38625 1 ide_cd ahci 23365 0 ata_piix 17993 3 libata 102745 2 ahci,ata_piix sd_mod 24897 20 scsi_mod 138601 4 sg,ahci,libata,sd_mod ext3 135497 1 jbd 63081 1 ext3 ehci_hcd 35533 0 ohci_hcd 25181 0 uhci_hcd 27725 0 I hope someone can help me... I couln''t find the problem... See ya! PS: I will send transfers rates under determined actions later... -- Arturo Hoffstadt Urrutia ahoffsta@alumnos.inf.utfsm.cl Estudiante de Ingeniería Civil Informática Universidad Técnica Federico Santa María "La magia existe, solo debes buscar mejor"

But i''m not a kernel expert, so someone with more and deeper knowledge of the drivers would have to comment on that. Have you tried running the laptop without the CDROM, just in case?
