Ummmmm my signature clearly states I'm using an A500, and I've never used Acer Sync in my life. Drag and drop files just like a thumb drive. It comes up as an A500 in win 7. You double click on the A500, and it will show 2 drives (internal SDcard, and external SDcard). Double click on whichever drive you want to copy files to, and drag and drop them in, or use "copy and paste". ;)
[Acer Iconia A500] ray1234:
That is using the PTP kind of protocol already, not acting like a thumb drive. Just do a simple test, copy one large file to the SDcard, and then before it finishes try to copy another file to it, it'll say the file system is busy. USB thumbdrive won't behave like that. Copy large number of small files in this PTP kind of protocol is much much slower than thumbdrive.

Also, try plugin in your A500 to a WinXP PC, it won't even recognise it without installing drivers for it.
[Acer Iconia A500] tumpy:
You are correct, only one at a time when copy files unless you highlight two at same time, if i connect the usb drive directly into win7 pc it will automatically add to the loading file, as for the recognzie pc acer do say that on their support page...

there is a auto sync option in settings under accounts and sync..
[Acer Iconia A500] kjy2010:
Of course WinXP needs drivers, that's a given. It's a 10 yr old OS! :rolleyes:

Your first post stated that you were using Acer Sync to copy your files.

I was simply wondering what kind of person would use Acer Sync to copy files when you can simply drag and drop them into your tab.

I tried what you asked. Started by dragging and dropping a movie to the tab, then tried d/d a few docs, and it indeed said busy.

When I chose them all at once and dragged and dropped them in, it copied fine, and much faster than a few of my thumb drives (three times the speed).

Question for you now. Why can't you simply choose all the files you want, drag and drop them into your tab and wait for it to copy the files, and be done with it? And second question is why would you ever choose Acer Sync to copy your files over?!?

;)
[Acer Iconia A500] ray1234:
I did, in fact I chose a whole directory to copy to the A500. My problem is the speed, with thousands of small files, copying the files using this way is slow in comparison to thumbdrive, at least double the time.... in fact, I can copy the files to a thumbdrive and then plug that thumbdrive in the A500 to copy to it, and I can finish the copying action faster this way than plugging in the A500 directly to the PC.... so speed for copying large number of small files is my only main issue

The side issue is winxp, without the USB drive mode, I can't connect to my office PC as I dont have admin rights to install programs on that PC... and one last thing, I probably put the subject wrong, I didn't use the Acer Sync, I'm using that PTP kind of protocol as per default, I thought that was Acer Sync at first ;)
[Acer Iconia A500] Neoprimal:
PTP or MTP? PMPs and most media devices use MTP. They're generally designed this way so that you don't corrupt files or damage the files on the flash drive by disconnecting without first removing the drive in Windows. It shouldn't technically be that much slower than a thumb drive if you multi-select stuff. I generally sync my mp3 list when I'm going to travel in case I don't have wifi and xfer time seems similar if not quicker than copying them to a thumb drive.

I'll try to see if I can get some small files, maybe pictures and test those.
[Acer Iconia A500] ray1234:
I know, theoretically it shouldn't be that slow. Practically, I don't know what's wrong with Acer's implementation of it, it is dead slow copying large number of small files. To give you an idea, the offline newspaper I copied is about 1,000 files, mostly html about 1k big. The jpg files are about 100-300k big. It took me about 15-20 minutes to copy those files to my A500 via the usb cable. If I take my SDcard out and copy the files direct to the SDcard using a card reader, that can be done in 3 minutes.
[Acer Iconia A500] Neoprimal:
I did another test using mp3s and the xfer was fast. Copied 150 files, 890MB total in 3m 35s using a class 4 card. That's around right.

Ironically, the same files took 6m 20s to the internal drive.

The only conclusion I can make at this point is that for some reason the bigger the file, the faster the transfer to the external SD. The smaller the file, the faster the transfer to the internal drive. This is all speculation.

Can you try copying them to the internal drive and let me know what you come up with? I myself am going to now try a comparison of 1 big movie file.

Update: I finished the other test. Puzzling. 1 MP4 file @ 2.26GB copied in ~3m to the external SD card.

In the same amount of time, just 1/3 of the file copied to the internal storage (I stopped that transfer, it was going to take ~9-10m).

I could only start to guess what's up. Maybe the A500 is actively scanning files being transferred to the internal storage and it ignores files smaller than a certain size or there's some other overhead going on and "noticing" media files, vs. any other kind.

The SD card is for the most part on the other hand, free and clear. I get the same results from my phone and its external SD, and that's connected like a Thumb Drive, as you put it.

Note that both the internal storage AND SD card are still accessible when the A500 is plugged in through USB, unlike most phones where the SD card is first unmounted.

What class microSD are you using? I think your best result might be copying directly to the tablet OR buying a faster microSD card.
[Acer Iconia A500] ray1234:
I did the test to internal storage, it is even slower than SDcard.

I did another test - copying 400 html files of 1-4k, a total of only 1.6MB. The A500 took 3 minutes to do that, while my thumbdrive finished in 18 seconds. The A500 can only do less than 3 files per second, no matter how small the files are, that makes copying large number of small files a pain in the a$$.

I used a class 10 SDcard, and the result is about the same, the problem is with the interface, not the SDcard speed. You won't notice the slowness unless you are copying files that are really small, if you copy MP3 files that is 5MB big, you won't reach the limit of 3 files per second anyway.
[Acer Iconia A500] interqd:
from reply i read

i assume people using win 7 DIDNT REALIZE that a500 use MTP, because a500 just shows up like a usb drive altough in reality they dont get any drive (they just dont care)

only people with mac and win xp will realize a500 use MTP ,
[Acer Iconia A500] powercat_:
I know exactly what you're saying. it's pretty horrible that the a500 uses MTP for file transfer.

Some workarounds I found was to transfer files using FTP, which is much faster for several small files so even over the wireless it'll be faster.

Also some other techniques I found were to zip the many files on my computer, transfer the zip and unzip them on the acer.

Also the other obvious is to plug the microsd card to your computer with usb.
[Acer Iconia A500] ray1234:
Yes, sadly I have to use other workarounds, there seems no way to use USB mass storage mode on USB. I now copy the files to a USB thumbdrive, and then insert that thumbdrive to A500 to move the files to A500. Even though that is twice the work, it is still much faster than using MTP transfer alone.
[Acer Iconia A500] FloatingFatMan:
It's not the A500's fault it uses MTP. You can thank Google for that as they're the ones who built it in to Honeycomb and dropped USB Storage mode.

Hopefully it'll be back in ICS...
[Acer Iconia A500] Biologos:
Alternatively, some file managers will allow you to send files via wifi to and from the tab. For me this is the prefered method (I use file expert, which is free). However, I noticed that occasionally large files like movies may fail, perhaps due to signal quality. I haven't had any problems with individual files up to 200-300 MB.
[Acer Iconia A500] erica_renee:
Hummmm not sure if this has been asked. Where are you putting the files at on your Iconia.If your putting them on the external SD card. Remember not all SD cards are treated equal.

Check the speed class of the card.and run a test to see how fast it can actually accept the files. Just because a card says class 10 does not mean its built well enough to handle that speed.

Internal storage can sometimes be slower then others as well.This would be considered a defective device.

I would surest to see if its faster or slower depending on where you store them.for me storing on my. Class 10. Ocl sd card..
[Acer Iconia A500] Micah_Droid:
This is even worst on a Linux system. Extremely slow transfer speeds. Also mounting and unmounting it is really flaky.
[Acer Iconia A500] Nova5:
The reason for this disparity between copying 800 megs of tiny files at around 1k-500k vs say 800 megs of 8meg MP3's or a single 800 meg video file is this..

File Start and End Headers. Each file needs a start and end sent so the receiving OS knows the data is starting and stopping, the sending OS has to generate these per file, the more headers that need to be generated the slower the transfer will be as each one is extra data that doesn't really exist for any reason but the transfer itself. You can see this effect on local copy commands from one point on a drive to another point on the same drive, from one drive to another drive, or across a network. There isn't a real way around this effect except to use a faster method. Gigabit network vs 100mbit network. Usb2.0 vs usb 1.0, but you are still limited to the speed of the method and the fact these headers/footers need to be generated and transferred.

Essentially the start header says

File Starting : XTZ.txt

Size : 2Kb

etc..

File end has things like

File Complete : XTZ.txt

CRC: 986a75

etc.

These tell the receiving system what the name is to be of its new file and other such stuff.. . Also every single data packet also has its own CRC so each one is checked as it comes in, but 800 megs of packets its 800 megs of packets(well, almost).. if a system can transfer 500K per packet and you are transfering 1K per packet, then you have a lot of wasted space. Each packet can only contain the data from ONE file. the files large enough to fill each packet to 500K move faster. Of course any path these files take that get pushed through a slower link creates a bottleneck. I doubt the iconia is actually checking anything, but the internal sd is likley on a slower connection than the external. Doesn't always make sense how that could be but it happens. Plus It could be a lower class memory module attached to the internal vs what we as users pay attention to and put in our external slot.
[Acer Iconia A500] jackie099:
I didn't find any ways to turn it off. I always use USB drive for copying files. It's much faster than it
[Acer Iconia A500] DeanGibson:
Use ADB

I'm looking for an answer to this as well. Meanwhile, I've found that using ADB push and pull works at a decent speed, will transfer entire directory structures, and also preserves file date/time stamps, which MTP doesn't. Using ADB is hardly user-friendly to most users, however.

---------- Post added at 10:11 AM ---------- Previous post was at 10:06 AM ----------

That's correct. Unfortunately, MTP is buggy (duplicate folders issue), aside from being as slow as a pig. That's why we want to disable it and connect to Windows like Android 2.x devices do: Each Android partition as a separate Windows drive (w/ drive letter), not as drives under a common device.

---------- Post added at 10:16 AM ---------- Previous post was at 10:11 AM ----------

Because MTP transfers are slow. When you are transferring 8 GB or so, you are looking at more than an hour.

Because MTP file transfers don't preserve the file date/time stamp.

Because MTP is buggy. Try changing something on the Android side, and then see if the change appears on Windows. Even disconnecting and rebooting the A500 doesn't get Windows to flush its cache; you have to reboot Windows.
[Acer Iconia A500] omniastrider:
When I bought my Acer A500, the first time I connected to my PC it was recognized as an USB external drive, now, after I disabled USB debugging mode on the tablet I can access to it only through MTP...I ask again, is there a way to disable MTP? Or maybe in Honeycomb 3.0 it was possible, but not in the next versions (3.1+)?

[Sorry for my bad, bad, bad english, but today it's not a good day...:()
[Acer Iconia A500] boystuff:
ok to modify the tab to read as a usb external drive would require some extensive software modification. it is possible as i've seen it done with ICS on the galaxy S phone, but again alot of work.

possible workarounds is simply copying files to your micor SD card usb card readers are dirt cheap, i think you can get a 13 in 1 reader at like bestbuy for less than 20 dollars.

second option is usb flash drive.

you could always try a program like drop box also? just copy the whole folder to the drop box folder and sync it via wifi to the device.
[Acer Iconia A500] omniastrider:
I see, in fact I use FTP transfer, now...but so MTP wasn't supported in HoneyComb 3.0? Was it introduced in version 3.1?
[Acer Iconia A500] boystuff:
i'm personally unsure when it was introduced. i know the galaxy nexus is the same way right now. but as far as HC goes i bought my iconia after it was being shipped with 3.2, but for me i personally don't even bother with connecting via usb i usually need stuff when i'm on the go in which case i use splashtop to throw files i need at that time into my drop box folder and just sync using my phone as a wireless router. lol
[Acer Iconia A500] omniastrider:
I found USB drivers on Acer website, but I installed them, but nothing happened...

What do you think are these drivers for?
[Acer Iconia A500] soks3d:
sync

wifi file explorer, works good and wireless, more than one file at a time too.
[Acer Iconia A500] boystuff:
the acer usb drivers are most likely (guessing here) similar to the samsung drivers i have for my GN and SGS, they are mainly used for Older OS's (xp,me,2k etc) and are most likely required for download mode (does this thing have a download mode?)

prolly also used for connectivity to ADB as acer customizes the stock rom to there personal liking then ships it out, thus generic google drivers wouldn't be stable/useable by the hardware.

---------- Post added at 04:00 PM ---------- Previous post was at 03:58 PM ----------

for the record here, i use windows 7 and i can clear as day tell the difference between "external storage device" and MTP as it shows up with a generic mp3 player icon and isn't even in the same spot as usb drives (windows 7 has seperators between drive types)

---------- Post added at 04:04 PM ---------- Previous post was at 04:00 PM ----------

i feel like the grinch here, but santa isn't real.. wait i mean Google left MTP in ICS. thats how my GN connects to my pc using 4.0.1 so don't get your hopes up unless it get changed in 4.0.2 really wish Google would just add a toggle under development settings so those who prefer each type could choose.

Hi everyone,

I got my Arc S a week ago and I love it. Or at least I did until about 24 hours ago. It started with multiple digits coming up for each touch of the pad to enter my screen unlock code, this was followed by having to touch icons multiple times to get apps/games/widgets to load up. This morning all hell broke loose; I went to use Navigation which loaded fine but after 5 minutes it decided to go back to the home screen. Tapped the icon, it loaded, it cancelled. And again. And again. Then it started freezing for short periods, now it is completely pot luck as to what happens when I press home or back buttons. It is unuseable. There is no pattern to it's actions, and I cannot find a way to cure it, can anyone help???

And yes, I have turned it off and on again! :-s

The 3 button combo to get into Download Mode is not working on my SGS2. This only started happening 2 days ago when I had a bad flash on Odin as I was installing a stock ROM.
