    with usb hdd backup on leopard 10.5

    There is a massive bug in the USB drivers for external drives that will cause data loss. If you are using an external USB drive for storing any important data, disconnect it from any Leopard (10.5.1) systems that you have, and don't use it until you know this bug has been fixed. Note that this also applies to any USB-based hardware, such as a camera.

    so mac users beware..

    edit: was wrong its 10.5 not 10.5.1

    What? And just after I ordered a Macbook Pro?

    Was hoping that all these major bugs were already fixed considering the laptop has been out for such a long time, but it looks like this is not the case.

    erm. does this affect raw files?

    i have about 1000 raw files on my MBP.. have not transferred to external HDD yet tho.. i used USB to transfer from camera directly or via card reader.. so far no issues at all

    read the blog post!

    basically this guy transferred files like all of us do
    never suspecting anything wrong until he did a check (checksum test or if jpg jus view the pic)

    u usually never check ur backups yah?

    IT AFFECTS ALL FILES TEXT WORD JPG RAW

    there is a new leopard 10.5.2 upgrade not sure if it solves the prob..
    ROFL some1 called apple sg and apparently the reply he got was apple can't read fat formatted hdd (which is wat usb hdd use for maximum compatibility)

    good luck to u if u r using leopard..

    Mind sharing the brand of HDD and casing you are using. Tks. (I'm really getting cold feet now...coz my iMac is arriving in the next couple of days )

    As far as I know, that bug had been fixed in 10.5.1, since it was on the list of things and people on MacRumors and other legitimate sites hadn't been mentioning further trouble.

    10.5.2 has other, more interesting things happening for me, but I'm sure a lot of things are fixed. It's just painfully slow for my PowerPC-based machine.

    hmmm actually why dun you try the experiment?
    move a couple of large files across partitions..
    then do random checksums test on the files?

    am willing to do the expt for public service if anyone donates a mac for me .. keke loan also can lah ..
    dun think apple sg would..

    Massive Data Loss Bug in Leopard
    November 5th, 2007
    Update: The bug occurs regardless of the type of destination being moved to (whether it’s local USB, local Firewire, SMB, etc.). Also, I have been informed that this bug goes back all the way to Panther.

    so definitely get the update.. hope no one lost any data yet..

    Definitely software.
    I find Vista more compatible on my Macbook than Leopard.

    In Leopard, it can't detect my external OTG HDD, FAT32 if u'd like to know.
    But when boot to Vista, everything works fine.

    So I used the FAT32 HDD and installed it into another cleapo external casing, and it works in both OSes.

    Ok.
    Results back.

    I tried with USB flashdrive.

    Tried to move a file to the target folder and I plugged the flashdrive out while the file is still moving.
    Finder prompted error. Had to relaunch finder because the progress window is still running although there's already no more flashdrive.

    Nothing was inside the target folder, of course.

    The file, 300++mb, was still in the flash drive.
    No data loss.

    Later I try again with a USB external harddisk with a huge photoshop file.

    This time I tried with an USB2 external casing with harddisk inside.

    Test 1:
    Power off while moving still in progress. Of course the file didn't manage to move over to the target. When I power back the external harddisk, data is still intact.

    Test 2:
    Moving target folder when moving of file still in progress.
    Nothing happens. Everything is fine and smooth.

    I'm using OS 10.5.2

    i got a reply about the bug
    it seems like it is present in 10.5.1
    but uncertain about 10.5.2

    i think the other thing that parka can do is to transfer a few large files and do a md5 check on the source file and the newly copied file in the usb HDD
    that's how you can know if there's a difference between the copied file. and whether it copied with any errors or not.

    updated to 10.5.2 and find that it's slower, and more problems with wireless connections.

    Ive had no problems with using usb drives, even when i was using 10.5/10.5.1. I might be lucky.

    As with wireless connection with 10.5.2. my signal seems to be better?
