tosh, of course it's possible, works the same as a USB hard drive, except it's wireless.

While the concept might exist I'm not aware of any in general distribution so I guess the answer to your question is no - what is it you're looking to do?

The question is not as irrational as you think. Currently, it is not pragmatic because Bluetooth 2 supports 2.1 Mbits/s whereas hard drives (both PATA and SATA) have burst rates of around 50-60 Mbits/s and sustained speeds of around 30 Mbits/s. As you are aware and I believe this may have led you to ask the question (of which I deem to be very logical and cognitive reasoning on your part), bluetooth is used as a means for data transfer, Unfortunately current specifications are not suitable for hard drive transfer but watch out for the next official ratification (the version number has yet to be finalised) because this will support up to 480 Mbit/s which is also the maximum theoretical speed of USB 2. As this exceeds speeds of current hard drives, it is quite capable of supporting file transfers from hard drives.

Sounds like you're thinking of the time capsule? These are wireless but it's wi-fi rather than bluetooth.

presumed they would be similar.
#14
Nope - they use the same frequency (as do many other systems such as DECT) but they're completely different protocols which use different hardware.

transfer via bluetooth, i would have thought that was obvious - lol
#16
It would be pretty slow so im guessing thats why none have hit the market. If it has to be wireless then a wifi drive would prob be the only option

Sigh...do you want help or not? Of course you're looking to transfer data but what type of data are you looking to transfer and between what devices? It may be you're wanting to extend the storage of your mobile phone or you're looking for a clutter free storage system for existing PCs. There is no obvious application of a bluetooth hard drive to me, if you let us know what setup you are trying to run then it may be possible to recommend a suitable alternative.

You asked about a bluetooth hard drive, bluetooth is a wireless protocol which is why any other recommendation would need to be wireless as that was your request.

oh john, lighten up, was only trying to be humerous, obviously unsuccessfully :oops:

Im not really trying to do anything, a friend has advised my daughter to maybe think about getting an extrenal hard drive to back up her new laptop, i got everything in it (blue tooth, webcam et) so she wouldnt have to keep pluggin unto the usb, as know from experience this loosens USB ports over time so just wondered if they did such a thing as a USB external hard drive :thumbsup:
#21
Ok - that certainly makes plenty of sense, unfortunately we're not quite there yet. There is a wireless USB standard which is upcoming which would do what you want but it's not out yet. It may be available in small areas but it's not really the mainstream system it will eventually be. You do get wireless nas drives such as the Apple Time Capsule recommended above but these tend to be a bit of a hassle especially for a laptop.

While I agree it is good to be cautious with hardware I don't find loose USB ports to be a problem with any of my machines. The main issue is just being careful the device isn't knocked when it's in and the cable is pulled straight out or wiggled gently if needed. Personally I use a 2.5in USB portable drive to regularly back up my machines without issue.

get a NAS (network attached storage) and so every time she is connected to her home network (even via wireless) she can connect to the hard drive and transfer data. :thumbsup:

Aftr 10 months of pluggin and unplugging an internet connection into my laptop it hard to go back to have a new motherboard as the usb stpped working, and dont want this happening to daughters. So was just curous, im not techy minded and still dont get the wirless thing, sorry do you mean it connects to my laptop wireless..............this is where i got lost:oops:

Now I know you are being humorous I am not sure if your original question was a very good question or you were jesting but regardless, I will answer your question with earnestness. A networked hard drive connected to a wireless router springs to mind. The drive will be connected to the switch on your router allowing any PCs connected to the network accessibility to the drive. If you search for NAS drives in search engines you will find more information about them. They are drives in an enclosure which contains a processor and an Operating System (usually Linux) which allows for networking features.

Another method is to simply network a hard drive that maybe installed or attached to another PC and allowing that drive to be viewable on the network.

sorry yes, my originol question in the op, was dumb but i was being serious, i was jesting when i posted post 19, anyway thank you all for your feedback, will look into the NAS thing

It is actually a very logical question to ask - not dumb at all! I am sure the NAS option or using a shared drive from another PC provides the least fractious solution. Of course, both methods require, respectively, either the router to be switched on or the PC allowing the drive share to be switched on.
banned#29
only got a desktop it could sit with, but its rarely used. If it was set up through that and that computer crashed and lost everything on its hardrive would we also loose whats on the external one (sorry again im not very technical minded as you can see)

it's almost reasonable to assume the laptop would be connected to the internet.

That isn't what I enumerated. I was suggesting that a server PC can be used wherby the laptop as a client to access the hard drive on the server PC.
#32
What's going on here then :whistling:.

By the way ElliottC I think 30 Mbit/s is a little low for a hard drive these days, don't you think.

Well yes and no. By the same token, a networked hard drive could develop a fault too although there's less risk of your router corrupting the hard drive than a server PC corrupting the hard drive. That answers the "yes" part but the "no" part is that data from corrupted or faulty hard drives can usually be recovered quite easily.

A server would use far more electricity than a nas. A nas is obviously the better option.

Effectively, a drive connected to your router could develop a fault too, just like a drive connected to your sever PC (via internal connections or external) but you won't necessarily lose all your data because this can be recovered by reconstructing the file structures, depending on the severity of the fault.

Essentially you have a server PC with a hard drive. As the nomenclature suggests this serves other computers by allowing connection to its hard drive via the network. Anything that connects to the server PC is the client as they retrieve data from the server. A NAS drive connected to a router operates on a similar principle whereby the router is the server (to all intents and purposes, a router is a PC as it contains an Operating System and a processor). Imagine a network whereby you have one computer (which can be your router) which serves everything that connects to it. It can be enabled to offer access of its connected hard drive to other machines connected to the network.

I've not really come across any decent current consumer NAS boxes, any time I read up on a certain one they seem to have various issues with speed, management and software support.

Another option if concerned about wearing out a USB port is to use an Express card USB adapter - if the USB port does break then you can just buy another express card. I would imagine the laptop has a slot for this, they just slide in and out as needed.

Current consumer NAS boxes are pretty awful in various different areas, I don't think they're a great recommendation for someone who's not particularly technical.

John


but what if she breaks the express slot? :w00t:

I've found that once a nas has been set up they work pretty well unattended.

a even simpler option (sacrificing some efficiency/speed) would be to use an NDAS device.... and they usually have two keys that you can connecto to... one with only read access and one with read write... so children can view content and not destroy it at the same time.
