    Slow transfer speeds since new hard drive added


    So I have quite an old PC running Windows 7 and Ubuntu, my laptop had died recently so I thought the logical thing to do was add the hard drive to the PC in the living room to give myself a bit of space amd also save some files, bad mistake.

    Since doing this my transfer speeds dont go above 1mb/s it was telling me it would take 14 hours to transfer 60gb. I looked around and tried a few things like disconnecting the sata and adding it via device manager when the PC had booted up but still the problem persists, i then tried to copy the files within Ubuntu which transfered the files within 15 mins at normal speed.

    This has obviouslt given me the conclusion that windows is telling it to go that slow for some reason and I can't for the life of me figure out why that would be, hence me coming here with you lovely people.

    The machine in question is old, its a 2.4ghz dual core pentium 3 with a 40gb ide hard drive and is primarily my download machine. The hard drive I added is a 250gb sata drive that was freshly formated to NTFS upon adding it to the computer

    Can anyone shed some light on this conundrum for me please

    Hi
    Did you add the ex-laptop drive to your desktop machine as secondary drive?
    If above is true, is this connectoed to the same flat cable as slave? You probably dont have any jumpers to set the laptop drive as slave so what I would do is to connect this alone with his own cable to your desktop secondary IDE connector making sure you use the primary connector on the drive end.

    Sorry I just realized that you mentioned the added laptop drive to be SATA not IDE as the original one.
    In that case yes, windows is seeing this differently as obviously Ubuntu its seeing it as it works okay when running in Ubuntu.
    I would be corious to see what happens if you connect the new drive through an USB Enclosure and see if is still extremely slow.

    Yes it still goes extremely slow. I have external hard drives as well as memory sticks and everything on the PC is slow since adding the new drive, even things such as unzipping a far file or copying a file locally. Adding that new drive seems to of screwed up the read/write speeds of the entire system

    HDD Errors


    Have you checked the HDD for errors?

    I've been playing with a damaged laptop HDD just recently (NTFS format).
    Windows won't even read the drive, but Linux Mint will.
    I have been able to save a couple of GB of files, but the transfer speed is ~1 MB/s.

    The damaged areas seem to be causing the OS to attempt multiple reads before eventually timing out and moving on.

    Disconnect the damaged HDD and you should see an improvement in performance.

    Well the hard drive isn't damaged or anything it works on other systems just fine as well as the laptop it came out of

    Hardware?


    You only have problems in one PC setup?

    Maybe there is a hardware problem on that PC.

    Have you tried using different SATA connectors on the motherboard?
    Are all of the other connectors properly seated in their respective sockets?

    Is your power supply in good condition?
    Maybe it can't cope with another drive being added to the system.

Hard drive transfer speeds?

Why am I getting such slow speeds. I made a second partition on my main drive and looking to transfer my DATA there, because its getting larger than I expected. Should it be this slow when transfer files within the same disk just one partition to another. Drive info: Seagate 1TB 7200.11
