    Laptop 2.5" HDD adapter, 44 pin-40 pin

    Anyone know where i can get an adaptor to use a 2.5" HDD on a standard ide interface, ie one that splits data and power in to two seperate connectors, mini molex and ide? preferably in the UK if possible. I dont feel like soldering anything on this, so i dont want to make up my own cabling!

    Thanks
    James

    I tried using one of these adapters with a Hitachi Travelstar 2.5" drive and encountered hard IDE controller errors being logged in WinXP event viewer (hard parity erorrs). I think the IDE timings that had been negotiated by the drive and motherboard was UDMA-5. Unfortunately the motherboard I was using didn't allow the user to manually back-off the UDMA mode in the BIOS. The best I could do was to install a 40 conductor cable to the motherboard which forced it to back off the timings to DMA-33.
    In the end I came to the conclusion that the corruption was being caused by the 40-44 way adapter. Has anyone else seen this problem and if so, does anyone know of a 40-44 way adapter that preserves signal integrity in the higher UDMA modes?
    I'm a bit peeved having this nice fast 7200RPM 8MB travelstar chugging away in DMA-33.

    [edit]
    I actually was using the Linitx (cabled) adapter. I see that the mp3car adapter is a socket and plug butted right up to each other with no visible intermediate cable. I wonder if one of these would give better results?

    I've heard a story about your problem.
    I think it was on mini-itx.com...
