Null Posted April 6, 2014 Share Posted April 6, 2014 This is why you should always make multiple backups and test them with important files. Quote Link to comment Share on other sites More sharing options...
Choppin Posted April 6, 2014 Share Posted April 6, 2014 I've has similar problems with using a stick. It's very volatile - sometimes it seems things just get lost and it doesn't work any more. I'm always very careful about removing it or inserting it when the power is off now. Quote Link to comment Share on other sites More sharing options...
Knuckles Posted April 6, 2014 Share Posted April 6, 2014 Pardon?????????? You have to completely turn off the PX just to remove the USB????? Oh no!! - I thought all you had to do was make sure you weren't in the media menus and then yank it out. Do you think I may have done any damage to my sticks?

Choppin Posted April 7, 2014 Share Posted April 7, 2014 I dunno. It's just a precaution that I take because I've lost so much material. I don't know if the loss occurs on taking the stick in or out of the px-5s or when I put it in the computer. I just know it has happened many times. It hasn't seemed to happen since I've been very careful about only taking it out and putting it in when the px-5s is powered down, but I may have changed other behaviors as well Quote Link to comment Share on other sites More sharing options...
Null Posted April 7, 2014 Share Posted April 7, 2014 In theory, the only time it is unsafe to remove a USB Flash Memory is while it is being written to. If you are uncertain that the operating system has not finished a write operation then yes, it is best to err on the side of caution and wait until the keyboard or computer has shut down before removing it. Pretty much every computer operating system has a "safely remove media" button which when pressed will tell you when it is safe to remove a mounted flash drive. One other item to consider however. Flash memory sticks have a limited operating lifespan before they actually crap out and no longer work at all. Flash memories typically are good for something like about 100,000 write operations before any particular memory register craps out and dies. Modern flash memories from reputable manufacturers have built in file allocation logic which minimizes the reuse of the same registers for subsequent rewrites in order to extend the life of the chip. However, if you are constantly performing saves, edits and resaves of the same files over and over again, be it on your computer or on your keyboard, you can effectively blow out a flash drive with a few months or years of continuous use. It is for this reason that I prefer to do all my saves and loads using the USB cable to the Data Editor program instead of saving modified patches to the Flash Card on my XW-P1 or to the Pen Drive on my Kurzweil. I tend to use the flash drives only for relatively static data, and again I always make certain that I have at least one or two backups of any data I consider worth saving. I hope this helps...

Null Posted April 7, 2014 Share Posted April 7, 2014 Here's a link to an interesting FAQ page with everything you ever wanted to know about Flash Drives. http://www.uwe-sieber.de/usbstick_e.html Quote Link to comment Share on other sites More sharing options...
User 29303 Posted April 7, 2014 Author Share Posted April 7, 2014 yep i wonder if we could use an external USB SSD on the port.....or other usb flash memory not only sticks....yes i know,.,.,.it can be broken damn, Quote Link to comment Share on other sites More sharing options...
Null Posted April 8, 2014 Share Posted April 8, 2014 I wouldn't try sticking any other sort of external USB drive on that port. It probably wouldn't work and it may end up damaging your PX. Quote Link to comment Share on other sites More sharing options...

Jokeyman123 Posted April 9, 2014 Share Posted April 9, 2014 Not sure about USB specs, but certain USB devices require more "juice" or amperage than others. All require 5V which is standard. Not sure what an SSD requires (pretty sure its a low-drain device) some of my USB devices require 1000mA minimum to charge or run properly, others need only 250-500. Those devices will also put that much drain or load on any USB port it's plugged into. I have several outboard hard drives that will not transfer data unless the USB port has enough "juice" or amperage to power it. Some USB ports will provide that, others won't. Since you might be "overloading" a USB port if you connect a high-drain device to it, yes it could damage components in that circuit. A 32GB thumb drive will hold an awful lot of data. Someone else already posted, alot of audio or other data will fit on a 8-32GB thumb drive. I have over 1000 midi files in one and several audio files, it barely uses the drivespace. Not all thumb drives are created equally, from what I've read there are only a few manufacturers that make the components in a thumb drive, but not all assembly factories are the same. A marginal solder joint can make a thumb drive do all kinds of strange things, or even have it fall apart, yes I had one of those. I fixed it with a hammer and a drillpress. Just call me cheap Charlie Jokeyman. Quote Link to comment Share on other sites More sharing options...
Jokeyman123 Posted April 9, 2014 Share Posted April 9, 2014 Sorry about the last post. I fixed it with a Skilsaw and a left-handed monkeywrench. I save the hammer and drillpress for the keyboards. 1 Quote Link to comment Share on other sites More sharing options...
