This review is from: Rosewill USB 2.0 Hub 7-Port HUB with Power Adapter (RHUB-300) (Personal Computers)
Worked well for a while until one day this hub fried 2 of my external drives in a row. Plugged one in and it wouldn't mount on my Mac and got a message that my drive was trying to draw too much power and was disabled. It was a seagate 3.0 1TB drive, relatively new. Plugged another drive that I just unplugged from another computer and same thing happened. Now both drives are dead.
It appears that Anker, Sabrent and perhaps Amazon Basics make reliable product any other suggestions for a USB 2.0 Hub?

  • MyFi?? You need a special card for Verizon "3G" - Don't waste time, get ATT

    I spent time in line and got a Verizon 3G Ipad2 today. I was told at the store, "plug it into a computer with Itunes and select your plan..." My Ipad2 wont do that, I don't have a Wifi signal. So, after 5 hours on the phone with both Apple and Verizon (Neither would just give a straight answer, "This is what's going on...") a Customer Service Rep at Verizon tells me about "MyFi", a special little card that allows the Ipad2l to work with Verizon. No one told me anything about this, neither at the Apple Store or at the Verizon Corporate Store I bought this at (Verizon Cor. Store told me, "It's a new product...it's going to have glitches", meaning even the people at Verizon don't know what "Myfi" is...!!)
    Bottom line-
    The Ipad2 will not work with '3G' unless I have this little "myfi" card. AT&T Ipad2s have it pre-installed()...
    So, I am supposed to keep track of this little 'connector card' to stay connected???
    "It's really small...", the Verizon rep says...
    Kind of defeats the purpose of the Ipad2 to have to carry a little card on my person....what if I lose it?
    Don't waste your time, like I did (5 hours on the phone!!!! Was told to go back to the Verizon store, which was just closing, told, "Sorry, come back tomorrow at 9AM..." after spending a $1K)
    just get the AT&T Ipad2!

    he said specifically that the Verizon model does NOT have a Mifi internally
    Correct. It does not. It has a 3G chip inside that allow it to connect to the Verizon CDMA cell network.
    only the At&T model does have it in it
    The ATT version does not have mifi in it either. It is not needed because it has a 3G chip inside that allow it to connect to the ATT GSM cell network. The ATT iPad also requires an ATT microsim card,network gives it the identification to use the ATT network. Verizon does not require a microsim.
    that is why you need Mifi to run Verizon with an Ipad2...
    You do not need mifi to use a Verizon 3GiPad 2. It has a 3G chip inside, the same as a cell phone.
    Mifi is a small, completely separate device about the size of a pack of cigarettes. It connects to a cell network and creates a "wifi hotspot" which allows wifi only devices (Verizon iPad 2 is not wifi only) to connect to the Internet when there is no wifi around.
    The 1st gen iPad could not connect to the Verizon network, so Verizon sold the wifi only version with a mifi device. This is not needed with a Verizon iPad 2.

  • Do you need anti virus software for mac book pro

    Is it true that the new mac book pro computers are now more susceptable to virus attacks and malware then the Mac books made  5 years ago.
    If this is true what is being recommended to protect your mac book pro?
    thank you

    OS X has got its own security systems, so you don't need any security application. Don't use any commercial antivirus. If you want more information about OS X and malware, see > http://www.thesafemac.com/mmg
    If you want an antivirus, use ClamXav or Sophos, but as I said, you don't need these applications.
    Now, there are some viruses for OS X. However, they are not serious, so you just need to keep your Mac updated, because the most recent Mac OS X versions include important security improvements

  • Do you need an anti-virus for mac

    Just wondering ??

    There are many forms of ‘Malware’ that can affect a computer system, of which ‘a virus’ is but one type, ‘trojans’ another. Using the strict definition of a computer virus, no viruses that can attack OS X have so far been detected 'in the wild', i.e. in anything other than laboratory conditions. The same is not true of other forms of malware, such as Trojans. Whilst it is a fairly safe bet that your Mac has NOT been infected by a virus, it may have another security-related problem, but more likely a technical problem unrelated to any malware threat.

  • Do you need a special external hard drive for iMac?

    Do you need a special external hard drive for iMac?

    Any external hard drive that will connect via Firewire 800, USB, or Thunderbolt will work.
    I have a 750GB Western Digital Scorpio drive in an OWC case, sitting on a Backpack, which connects via Firewire.  Western Digital Scorpio drives have 5 year warranties, the OWC (macsales.com) cases usually use the Oxford chipset which works well with macs, and the Backpack is a slick way to mount a backup drive without taking up desk space.
    After you hook up whatever external drive you end up with, you'll partition and initialize it for OS X, then begin using it.
    My opinion, I would not get a Western Digital pre-packaged external drive/case.  While the hard drives are OK, there have been a number of people that have had issues with the electronics.

    I’m going to get the I Mac and since the new I Mac doesn’t have DVD drive on it I was thinking to get the Samsung SE-506AB Slim Portable Blu-ray Writer in order to burn movies from I movie do I need a special software for that since the SE-506ab comes only with windows software.. but I did check and it is compatible with apple. Can you please advise me and or let me know if I’m buying the right stuff or if there is any other blu ray that will work with the I mac as plug and play.

    This freezing reminds me of really old Macs, long ago, in the days of the old-school peripherals like SCSI drives, terminators, scanners and the like. If you had a SCSI conflict, like the wrong device ID's or something, you'd freeze up like that. Back in those days you'd call 800-SOS-APPLE (AAPL?) and they'd run you through disconnecting all your extra hardware - Jaz and Zip drives, CD burners, scanners etc and then eliminate them one by one by adding them incrementally and testing for the freeze/bomb dialog.
    But, today we have Firewire and none of those ancient issues (no free lifetime tech support either). My iMac's ports are all full, and I only know which devices are connected when I have to remove something for another device. iSight, scanner, card reader, external hard drive, USB soundsticks, etc. You wouldn't happen to have any SCSI devices hooked up, would you?
    Out of curiosity, have you tried a different USB/Firewire port for the hard drive? Or run the hardware test DVD that comes with your computer? This weird freezing seems to suggest a problem with the computer, RAM or network more than a device. Bad devices, in my experience, cause kernel panics, not freezing.

  • I have an iPad 32 gb - do I need a special charger for it?  The charger for the newer iPads seems to fit but it does not charge it.

    I have an iPad 3 GB - do I need a special charger for this older model?  The charger for a newer iPad seems to fit, but I do not get any kind of display that it is charging.

    Did you try another cable?
    If you are using a USB to iPad dock connector (older iPads do not use the newer Lightning connector) then
    The Dock connector or the USB cable may be bad.

    You could try calling Apple and ask for Customer Relations.
    From Readers Digest-February, 2005
    How to Complain
          You call customer service to complain about a product, and you hang up angrier than when you started. That’s customer rage, a feeling experienced by millions of people with a major complaint, says Scott Broetzmann, president an American firm that tells companies how to offer the best customer service. His secrets to getting good service:
    Have a goal
    If you want your product repaired, say so. Want an apology? Speak up.
    Keep it short
    Focus on one problem, and be succinct.
    Stick with it
    You have to invest the time it takes. Don’t get what you want? Ask for a supervisor.
    Skip ultimatums
    Don’t threaten not to do business with them again. Why should they help you if you won’t buy from them in the future?
    Plead your case
    Many companies have information such as how much money you’ve spent with them and how often you complain. If you’re a good customer, they may be more willing to help.
    Be nice
    You’re unlikely to get what you want if you’re rude.
    Good luck.

    Unfortunately, no Sanyo phones are iSync compatible so you will not be able to synchronize your Contacts and Calendars with the phone.
    Also, you may have problems with the Bluetooth adapter you purchased, as the only one officially supported by Apple for use with Macs is the D-Link DBT-120.
    The Official Apple list of iSync compatible devices is here:
    http://www.apple.com/macosx/features/isync/devices.html
    It's always a good idea to check this list before purchasing a new phone.
    Other phones are supported by third party plugins from here and here. But still no Samsung, Sanyo, LG etc. who all use thier own proprietary syncing protocols rather than the industry standard SyncML. These manufacturers also don't provide Mac software with their phones like the do for Windows users.
    I'm afraid you're not going to have much luck if you stick with the Sanyo. I would seriously consider taking it back and swapping it for one of the handsets on the above linked pages. Personally I would recommend a Sony Ericsson model. I've always had excellent Mac compatibility with those.

    Do you need a screen protector for iphone 4s ?

    It depends on how you handle and use the phone.  If you put it in a pocket or bag with loose change, keys, grit, etc, the oleophobic coating will likely scratch and sometimes the glass will scratch as well.
