Too slow transfer speed for Toshiba 3.0

Hi there
i just purchased a toshiba 3.0 external hdd.
I use windows 7 genuine.
My pc specs are pretty ok cos i am able to run heavy games like crysis 2.
The problem is, My external hdd has slow transfer rates. This problem i started facing aroung 3 months ago. My hdd is out of warranty.
My USB ports are ok and i connect it to primary port.
The transfer speeds are just around 10MBPS and sometimes it drops to KBPS!!!!
Also, it does not copy some files and gives error "Failed to read from source disk" or something like that.
There is no Virus in it, I have enabled write-cache. I have defragged it.
My OS is fine and also, i checked it on other OSes.
Also, i have tried using "check disk for errors" with proper procedure but it hangs somewhere in the middle after it processes 500000 sectors or so.
I got my HDD from my cousin as he no more used PC and without any cover so i dont have any idea of model (although if there is any utility to find model then please notify me).
Also, it worked fine during then. Me and my cousin are from India only.
How can i fix this issue?
Please help me.

  • Slow Transfer Speeds For File Transfer Manager 5.0 Build 0032

    I have a 20Mbit internet connection. When I download from the Microsoft download site I can get files downloading at reported speeds of up to 1.7 Mbytes per second.
    When downloading from the TechNet Benefits section I have to use the Transfer Manager and I can only get speeds that vary between 30-80 Kbytes per second. Rarely any faster.
    I am using XPPro & IE7 straight out onto the Internet via my router / firewall. No proxy server.
    What can I do to speed the process up or bypass the File Download Manager?
    Regards.

    Thanks for your feedback Tekky.  FYI there is also a forum specifically for TechNet Website Feedback which is the more appropriate place for TechNet Subscriptions questions at http://social.technet.microsoft.com/forums/en/tnfeedback/threads/
    There are many suggestions in this post about improving your network speeds when downloading from MSDN and TechNet subscriptions sites.  Here is one more place to look for tips, which we have linked to from our Downloads and Product Keys FAQ (MSDN version, TechNet version): 
    The website for the Microsoft File Transfer Manager, particularly their troubleshooting page which includes additional discussion on configuring the FTM and on slow transfer speeds. 
    As Julie stated above, you can call TechNet Customer support and they can take you through some additional troubleshooting and diagnostic steps to assist.  Julie has linked to the support phone numbers in her reply.

  • External firewire hard drive reverts to slower transfer speeds

    This is the strangest hardware problem I've come across. I'm running a unibody mbp (June 2009) with an external WD 2.0TB Caviar Green drive mounted in a firewire 800 enclosure made by icydock.
    Lately, I've noticed that after an unknown amount of uptime, the speed of file transfers to the WD external drive slows down dramatically. I figured this out by watching my time machine transfers take a bit longer after awhile, and I verified this using aja system test and speedutilities.
    When I boot my mbp in the morning, file transfers and time machine backups to the external WD transfer at a rate of about 67-75MB/s. This is the speed the drive should always be working at since it's connected via firewire 800. Aja speedtest verifies the speed is as it should be as well.
    Then, after a couple hours of using my mbp, or even later in the day, I'll transfer a file to the external WD or run a time machine backup and find that the transfer will only run at a max of 29-35MB/s. This is exactly half the speed the transfer should be going at. Subsequent transfers stay at this slower rate no matter what I do.
    However, I've been able to fix this problem by unmounting and remounting the external WD or restarting my mbp. After doing either of these actions, the WD external goes back to contant transfers at 75-80Mbs. So something is happening where the longer the mbp is running, or after some sort of disk activity, the external WD reverts to a slower transfer speed (closer to FW400). I can't isolate whether it's an issue on the mac os side or the hard drive or the hard drive enclosure because I can make the hard drive go back to optimal speed again merely by unmounting and remounting it. This works consistently until a few hours later when the drive begins to handle transfers at half speed again.
    I run hourly time machine backups to the drive. The time machine backups can't be the culprit because the drive remains running at optimal speed after the backups (verified with aja system test and speed utilities)
    Any possible ideas as to why the drive cuts down to half its optimal transfer rate after a bit of time? I can't figure out the cause of this, and the consistency of the drop leads me to think this is an issue with the power management on the drive since it reverts to full fw800 speed when I umount and remount the drive or restart my computer. Could this be an OSX issue where for some reason the system isn't negotiating the fastest speed?
    Any help appreciated.

    From the SoftRAID manual:
    Fire hubs and disk drives. FireWire hubs are notorious for introducing errors and instability onto the bus.
    Make sure that all of your consumer electronic devices (iSight, cameras, scanners) are connected to a separate FW bus. These devices are not built to the same standards as storage devices and known for introducing errors onto a FW bus.
    Cables. While most cables work fine with a single device, many cables will introduce errors when 2 or more disks are connected to the bus.

  • Slow transfer speeds between Mac Pro and Shared Drive on Windows Domain

    Hi Guys,
    Getting really slow transfer speeds when I try and transfer a file from a Mac Pro to a shared network drive on one of our Windows 2003 Servers.
    The Mac Pro is logged on to windows domain. This data is transferring via our hard network, not via wireless. Not having any other transfer speed issues on any other PC's.
    For example an 8mb file took around 45 mins.
    Hope you can help. Many Thanks.

    I saw this at a site where they were using DFS with Server 2003. When the few Mac's they had connected to the actual server and uploaded the file it was okay. But when it was sending the file via the \\DFS_node\share_name the Mac took heaps longer for the same file. Watching the Activity Monitor > Network monitor you could see gaps with the data transfer, as if there was some pausing between packets. A pcap showed that there was constant DNS requests coming from the Mac, even after the connection to the share was made. The same wasn't happening when the connection via SMB was directly to the actual file server. As there was only a few Mac on site they left it with the direct connection but were getting an MS specialist in to look at it. Never heard what happened with that one but you may want to try monitoring the packet transfer to see if the data movement is contstant or breaking. I'd also recommend getting Wireshark to monitor the transfer. You can compare upload to download and maybe even the transfer from the Mac to an MS workgroup share.

  • I need to update to the latest version of Snow Leapord-currently running v10.6. Because of where we live the slow download speed for such a large file has kept me from downloading the update. What can I do short of hooking up computer elsewhere?

    I need to update to the latest version of Snow Leapord-currently running v10.6. Because of where we live the slow download speed for such a large file has kept me from downloading the update. What can I do short of hooking up computer elsewhere?

    Do you ever visit a friend or realtive with a Mac who has faster internet? Maybe the local library has Macs on a fast line. If so, get a USB thumb drive and put this link on it from your computer:
    http://support.apple.com/kb/DL1399
    Then put this link on the drive:
    http://support.apple.com/kb/DL1429
    When you are at some place that has a Mac with a decent download speed. insert the thumb drive in that Mac and click on the first link ("DL1399") and direct the download to your thumb drive. Now do the same this with the second link.
    The installer files will now be on the thumb drive and, when you get home, drag them from the thumb drive to your desktop. Install the Combo update first.

  • External hard drive, error -36, corrupt files and slow transfer speeds

    This is a long post but stay with me.
    I've got an external 250GB Lacie drive connected to my 24" Intel iMac via Firewire 800. I have approximately 80GB worth of files (including my iPhoto library) on the Lacie that I'm trying to move over to my iMac but have run into some frustrating problems.
    Overall, transfer speeds are erratic – fine at times and SUPER SLOW (5 minutes to transfer a 3MB file) at other times. At first I was transferring entire folders, but after always getting errors (error -36 to be exact), I was having to transfer individual files. This works fine as long as the files aren't too big (which makes the transfer speeds SUPER SLOW) and not corrupt (which gets me an error -36). Is my Lacie crashing on me? Is there any hope?
    Here's what I've done to try and salvage my sanity with no resolve to my problems (not exactly in this order):
    1) Ran Disk Utility to repair Lacie. Everything came back OK
    2) Ran Disk Warrior on Lacie. Found a handful of bad items that Disk Warrior was able to repair. Had Disk Warrior replace the old directory of the Lacie with the new directory.
    3) Ran Drive Genius: Raired and Rebuilt the directory, did an Integrity Check (came back OK), attempted to Defrag but could not because of errors to the drive, did a Scan for bad blocks (which after running for 3 days! it was only 20% complete and had found over 150 bad blocks, at which point I quit to try something else)
    4) Checked that my Firewire cable was properly connected and replaced the older one I was using with a brand new one.
    5) Disconnected all peripherals except for keyboard, mouse and Lacie.
    6) And at times, even viewing a file on the Lacie has caused my Finder to crash, requiring a restart of my iMac.
    I'm sure I've left something off I've tried but you get the idea.
    I've read that maybe I can transfer my files using Terminal. Yes/No? Does this bypass any corruption the files may have?
    What about creating a second partition on the Lacie and moving files over to the second partition? Does this solve anything? I don't know anything about partitioning so maybe I'm talking crazy.
    I've also read that iPhoto tends to corrupt files which makes me hate iPhoto, and myself for not backing up.
    And I've read a lot about error -36's and none of it sounds good so I'm just hoping that someone might have other suggestions for me to try and save my files (especially my iPhoto files which include baby pictures that if I lose, my wife will kill me).
    So if anyone has any ideas, let me know. Please. I'll try anything.

    Hi Aaron Thompson-
    I am fairly certain you have a bad power supply brick to the LaCie drive. This is a hard problem to troubleshoot as generally when the bricks go bad they do so slowly and the drive appears to power up and stuff but it just doesn't work.
    If the drive is under warranty LaCie will replace the brick at no charge. Otherwise they sell them for around $20US on their website.
    Luck-

  • Very slow transfer speeds with external hard drives through Firewire and US

    Hi All,
    My external drives transfer very slowly on my MacPro. I've been searching for answers and have turned up very little. Apple support suggested I post my issue here. Just to make a note, I measured my disk speeds with both AJA System Test and copying files between drives and reading the Disk Activity in Activity Monitor.
    I have 3 external drives, all MyBook Premium or Professional, 1x 500GB, 1x 1TB and 2x 1TB in RAID 0. I had them on Firewire 400 and the RAID 0 2TB one on Firewire 800. My transfers on FW were all around 24MB/sec on all drives (much less than what I should be getting with FW400). I then read somewhere that the FW bus on the MacPro uses the slowest speed connected for all FW connections. So I unplugged everything but the FW800 Raid 0 drive and my transfer rate jumped to 40-60MB/sec. This is much better, but still about half or so of what I expect it should be producing from an external RAID 0 setup.
    To keep my FW800 backup drive faster, I've plugged the other two into USB2.0. The transfer speeds on both drives are now hideous, around 10-15MB/sec. This is so slow, but I'm not sure what to try to fix my speeds.
    The HD's in the external drives are all 7200rpm, and all should be transferring at a higher rate. Do you have any suggestions or ideas? Ideally I'd like to get everything transferring at rates they should be transferring at, but I'll settle with my current FW800 speed of 40-60MB/sec if I can get my other two drives transferring at a non-snail pace.
    Is this a common issue? I can't believe I'm the only one plugging multiple external hard drives into their Mac Pro. I hope someone has a fix or solution for this. I'm all ears!
    Thanks in advance.

    Hi Kappy, thanks for the information.
    So I rejigged my setup a tad. My RAID 0 is still FW800, the second drive is back on FW400 on the back port, and the third is USB 2.0 on the back as well.
    It's interesting to note that I saw the FW800 taking a bandwidth hit if the FW400 drives was being read/written to. For example, if I was averaging 50-60MB/sec on the FW800 drives and copy something large to the FW400 drive, each drive averages out to about 30/MB second, roughly half the FW800 speed I was getting. The USB while the slowest didn't cause any slowness on the FW drives.
    Here are my Xbench results. These results are from each drive being benchmarked individually with no other drives being tested at the same time.

  • How do I fix the slow transfer speed over USB on my 24" iMac?

    I am backing up/cloning with SuperDuper, and running Lion.  The displayed transfer speed never gets past about 20mb per second.  Painfully slow....  Any suggestions?

    Actually that's pretty good for USB. USB is slow - there is nothing you can do about it. Firewire always has been faster. Personally, I only use external Firewire drives for cloning or backing up. Even then, if it's a fresh clone, it'll take moe than an hour for 160 GB.
    So, I schedule it when I have other things to do and walk away until it's done.

  • Very slow transfer speed between 2 computers in the same network

    I recently bought a new laptop (Lenove G510) with win 8.1 pre-installed.
    When i download files of the internet, my speed is ok, for wireless, but when tranfering files between computers (The other computer is a win 7), the transfer speed is really slow (2-4 MB/s). The transfers takes forever, and are relly unstable. It bounces from 1 - 4 Mb/s all the time and will not stabilize.
    The same applys when streaming to other devices (Media Center). The video being streamd will just go frame by frame, and it is no fun watching...
    Why is my transfer speed in local networsk so slow?? How can i fix this?
    I use AVG Anitvirus, and I have tried disabeling it before transer, whitout results...
    I have also updated BIOS, Chipset and the driver for the wireless network card...
    I can also mention that when I turn my computer on, the internet connection is lost to all other devices... I then need to reset the router, and then the connection is fine again. This was never a problem before I got Windows 8.1, and is not a problem while the computer is turned of.
    In advanced, thansk for any replys/tips

  • V. Slow transfer speeds with new dual band Airport Extreme

    I have a new Airport Extreme (late 2009, dual band, full 'N' spec) which I am using to replace an older Airport Extreme (early 2008, 5Ghz, 'draft' N).
    I have a USB disk attached and was interested in benchmarking the transfer speed of the new Extreme, compared to the previous version. The results are puzzling / alarming.
    Shown below are transfer speeds (file copied to the attached USB drive) under different connection standards (2.4Ghz / 5Ghz & a/b/g/n)
    'Old' Airport Extreme
    5Ghz - 'draft' N : ~5-7 Mb/sec
    'New' Airport Extreme
    2.4Ghz - b/g : ~3-5 Mb/sec
    5.0Ghz - a : ~3-7 Mb/sec
    5.0Ghz - N : ~200 Kb/sec
    Hence transfer speeds appear to collapse when I try to make use of the 'N' spec with the latest Extreme. I have tried altering items such as - wide channels (on / off), interference robustness (on / off), 5Ghz channel (manual, instead of auto), with no upside.
    I seem to be at the point of concluding that either
    1. I have a 'broken' Airport Extreme
    2. The WiFi card on my early 2008 iMac (which implements I guess the 'draft' N standard) is 'incompatible' with new the Airport Extreme under a 'N' connection.
    Any thoughts ?

    Since all devices in my wireless network are capable of latest 802.11n protocol, I really do not need older and slower 802.11a/b/g protocols. To achieve above 200 Mbit/sec, 5GHz band with wide channel option turned on is really necessary. Thus I really wish I can turn off the 2.4GHz radio band (seems Apple has set this band as default) of my new dual band Airport Extreme to avoid unwanted bandwidth degradation. Unfortunately this is not possible with radio mode setting in Airport Utility.
    The best I can do to force connection with 5GHz radio band (with quite consistent result) is as follows:
    On Airport Extreme through [Airport Utility>Wireless] :
    Radio Mode: 802.11n only (5Ghz) - 802.11b/g/n
    More Options>Wireless Network Option>Transmit Power: 100%
    More Options>Wireless Network Option>Use Wide Channels: checked
    More Options>Wireless Network Option>5 GHz Network Name:
    checked and same network name with extra suffix "(5 GHz)"
    On 27" iMac through [System Preferences>Network>AirPort>Advanced>AirPort]:
    Preferred Networks:
    Create only one profile in Preferred Networks for the above network name with suffix "(5GHz)"
    Uncheck the option [Remember networks this computer has joined] to ensure there is only one profile under Preferred Networks .
    Once all above settings are done, restart Airport Extreme in Airport Utility. Your computer should connect wirelessly to the base station through 5GHz band after booting most of the time. Even when it is not occasionally, simply go to the Airport icon in main menu bar and click on the network name with suffix "(5GHz)" in dropped-down list to connect manually. With all these settings, I have achieved 300 Mbit/sec bandwidth on my iMac most of the time for fast Time Machine backup.
    How I wish feature for better radio mode control by end user will be implemented in next update of Airport Utility. Apple should trust end user's brain better than artificial intelligence (or ignorance ?) in wireless network implementation. Wireless traffic between the two radio bands and among various wireless devices should be segregated specifically in Airport Utility by end users whenever dual band Airport base stations are in use.

  • Advice pls: V.slow transfer speeds to external FW HDD ... but not always!

    I've a WD MyBook Premium 320Gb external drive and I'm getting very poor transfer rates via firewire.
    Most of the time I drag and drop multimedia files (mpg or avi) between Finder windows and I get transfers of around 300-350Mb/minute. However on two occasions recently the rate has increased to roughly 1Gb/minute. I can't account for why there is such a huge differential in transfer speeds in the same file type - and neither can Western Digital.
    By way of comparison I get roughly 1Gb/m transfer speeds from a USB2 Sandisk flashpen to the iMac, matching the speed increase I've seen on two occasions via firewire.
    So I guess the questions that arise are
    1. what speeds should I get when transferring large files across firewire? I don't expect the theoretical 400mbps sustained.
    2. would speeds be better using USB2?
    3. what format should the external drive be and does it make a difference to performance? It's currently HFS+ Journalled though WD say that's not ideal.
    Thanks

    I've been digging around a little more and I've found a CNET review of the most popular external drives and Seagate was worst but the MyBook wasn't too fast except for reading whereas the IOMega was the fastest for writing via firewire but not USB.
    I think I'm going to have to live with the performance poor though it is for writing. Hopefully the format will improve things a little, if not it's one of the most attractive drive out there so I'll have to appreciate it for its aesthetics.

  • HARD DISK replacement because of very slow transfer speed

    thanks

    Hi,
    If you weren't using USB, then were you were transferring data between partitions or to a multimedia flash drive?  
    Have you mistaken a partition (primary or logical partition) for a physical drive?
    Your notebook has four partitions, unless you have changed the original factory partitioning scheme. C: D: System and HP_Tools.
    The following image shows how my loaner  Envy17-3002ea is organized. It is a bit different as it has two physical 750 GB hard disks. Everything as showng inside Disk 0 is a partition. 
    What software did you use to determine the transfer speed? 
    Which CPU is installed in your notebook?

  • Slow transfer speeds between two macs

    The general setup: an iMac Intel 20" and an iBook G4 1,2GHz connected via an Airport Express (newest edition), both computers running 10.4.7.
    When trying to transfer files via AFP between the two on my local network, I get "tremendous" speeds of about 0.5-1 MB/sec. Why is this so incredibly slow? Is it because of encryption or something similar? I can download off the internet with greater speed than that!

    i have exactly the same problem , using a macbook black g1 . slow network speeds and flakey internet . these were ok when I first got the machine . but are now slow as . using the network view of menumeters I see that if i try and shift files from my mac mini they are incredibly slow with menumeters show 0.0kb/s for seconds at a time .
    to trouble shoot this problem I used another friends macbook configured with exactly the same settings on this network and the transfer speeds were as they should be which was about 1.5-2.5 megs/sec .
    so i figure there is some preference corrupted but which one ?
    I have experienced several crashes recently . because of the overheating bug I have the fix applied to my machine and the firmware update . Maybe the network preference got corrupted at that point .
    any tips as to which preference to delete would be appreciated .

  • Slow transfer speed

    Hello, I have a few years old WD MyBook Live 2TB and I haven't used it much since I bought it (new).The problem is, that transfering speed is ultra slow. It can't go past 4MB/s and that's max. And after all, I even tried connecting it directly to my pc via LAN, but still no chances going beond 4MB/s .. My USB 2.0 is faster.I heard this product has really bad processing unit inside and thats the reason for all that, but still, has anyone figured out after all those years, how to fix this problem? After all with that slow transfer rate, it's unusable.. Thanks!

    Well, what is then? I'm using utp cable which was included in the box and I have Broadcom 802.11 ac adapter in a laptop with i7 4700HQ and 16gb of ram.. I don't see the problem on my side. And like i said, i connected it straight in to the laptop, so no router between.

  • Transfer speeds for internal drive/FireWire

    I have a 2 yr old PowerMac G5 with a single 160 Gb hard drive, so I have an internal drive bay available that has a 150 MBps SATA controler. Does that mean I won't get the expected speed from one of the big Seagate or Maxtor internal SATA drives with 1.5 or 3 Gbps transfer capacity?
    If that's true, would I get faster transfers using an external drive via FireWire 800?
    Thanks!

    The maximum transfer speed of the 1.5 Gbps is actually about 1.2 Gbps (80% efficiency), or 150 MBps. So, in theory the 3 Gbps interface would be about twice as fast.
    However, no single drive can achieve throughput at even the 1.2 Gbps level, so you're really not missing anything if you put in a drive with a 3 Gbps interface on it.
    FW800 is 800 Mbps or 100 MBps at 100% efficiency. Real world transfer speeds would be in the 80MBps range at best. That's also a pretty tough speed to reach for a single drive. My 10,000 rpm 150GB Raptor drive can benchmark at or above that level, but many drives won't be able to.
