    It also depends on your hard drive. I have 1 Tb WD Scorpio Blue it supports UDMA6 as well.

    Are you sure it's UDMA2 not MDMA2?

    Yes, hdparm had a * at the UDMA2 option, but it showed that MDMA2 was also supported

    I got ICH4M and my read speed is 99 MB/s, but write speed is only 24 MB/s. By default Baredit shows 00001011 for 0x54. What should be there ?

    I think it's fine, write speed could be related to HDD.

    Your drive seems to work in SATA I though.

    You can also try altering this value to 1033, but don't think it'd help.

    What ? This disk is capable of running up to 280 MB/s read speed and 250 MB/s write speed, so hitting 100 MB/s on ICH4R shouldn't be a problem.

    you gotta be kidding

    I had laptop on ICH4M, there is no SATA interface at all. Only IDE. It's a very old chipset from 2003 for laptops.

    And if you're using SATA->PATA caddy don't expect speeds more than 100 mb/sec (it's limited by chipset I think, even if you have your drive working @ UDMA6).

    Overall, it's not a good idea to put high speed SSD into PATA caddy, you probably need to upgrade your laptop to get SATA II speeds at least from your SSD.

    I know, but why write speed is so slow. It didn't speed up after forcing udma6. While read speed jumped from 31 MB/s to 99 MB/s.

    The answer is simple, most of the SSD's are not working quite good on old hardware especially on SATA-I interface converted into PATA...

    Better get proper hardware..

    Who can help me modify BIOS Acer 5553g for working with double HDD? When I connect second hdd (using caddy), laptop freezes at bios POST checks, no errors, but when it should boot up Operating System nothing happens. As normally it shows Press F2 to enter setup. If I press it, laptop reacts, shows entering setup and again - nothing happens. I can`t even enter bios setup!!.
