Hi,
I recently bought a 7501 and am loving it. When I played Xvid movies with TCPMP 0.72, I have trouble with the video performance. When the movie is on my Class 6 miniSDHC card, there's significant fram drop, the video is jerky all the time. When the movie is on the microdrive, if I turn off the "microdrive mode", it plays smoothly, but the microdrive is spinning all the time (I can hear it if I hold it close to my ear). This is surprising to me, as I bought the miniSDHC card to store and play my movies, so I don't have to use the microdrive for that. Am I missing something here or this is the way it is? Thanks for helping!!!

My videos are all in the microSDHC cards and play without problem.
I suggest you do a SKtools benchmark test to find out how your card is doing. I had problem similar to yours in the begining because I incorrectly formatted it. This problem also happens when there is corruption, lost clusters, etc. You might want to first copy your card content to th PC, then format your card (Make sure your formatting parameters are: Fat 32, no fat table backup and cluster size 32k), then copy your PC's files back to the storage card.
Let's see how it goes.

Thank you for the suggestion. I followed what you said and the performance doesn't improve. I then benchmarked the MiniSDHC card with Pocket Mechanics and the score is very low, much lower than a stone age 64 MB CF card, and much lower than the built in microdrive. Pocket Mechanics couldn't find any bad sectors. I tend to believe there's something wrong on the data transfer between 7502 and the MiniSD. What would you suggest next? Should get a replacement? Thanks!

How low? If it is very low, the service centre is likely to ask you to re-flash the ROM, and check the speed again. If after that it is still low, they would ask you to send it in for analysis.
I compared the file transferring speed of the Class 6 MiniSD with my Class 2 SDHC. I basically transferred a 1.2G movies file to both cards. It took 7 minutes for the SDHC, and 28 minutes (!) for the MiniSD card, to finish the transfer. I tend to believe this is a bad card now. I am going to get a replacement. Thanks for helping!
This might help you out
Take a quick look at this http://panasonic.jp/support/global/cs/sd/download/sd_formatter.html
It's a SD Card formatter from Panasonic that works with pretty much all SD, MiniSD and SDHC cards not just their own. I had a 4GB SD that was giving me trouble on my old Universal but gave it a run through this and seemed much better. It should work for your card as long as you have a card reader for your PC. It's seems windows own formatter does not quite work as it should with SD's as this seems to do things a little differently.

Hi, I purchased the Transcend 8GB Micro SDHC TS8GUSDHC6 about 3-5 Mo ago, for my AT&T tilt/8925, The issue I am having is that after about 1.9Gb, has been written to it, the transfer will either fail, or it will just sit and the completion will raise indefinitely. I do not have a SDHC compatible reader for my Pc, nor do I have another card over 2Gb. I was wondering if the phone cannot address over 2Gb, or if there may be something wrong with the card?
Hy
maybe i ma wrong, but i think you must format the card in "FAT 32". if you formated the card in "FAT" you can't get it over 2 GB... i don't it for sure

If you are attempting the transfer using Activesync:
You are very patient
Activesync is incredibly slow for large file transfers
Activesync has a bug where it appears file transfers are starting again continuously even though they do go through (eventually).
If you don't have a compatible card reader and have not partitioned the card, it should have already come with a Fat32 partition so DrWinstons concerns shouldn't be an issue. If you've put it in another (old) device to wipe it though, this may well be what's happened. Where has the card been?
The card was bought for this phone, and has only been in it. as far as active sync, it will write 1.5gb in about 35-40 min, then if I try to add another 1.5gb file, it will say 35min and count down for a few minutes, then suddenly the transfer bar, seems to stop and the timer goes up to over 2Days, and will continue to raise, I have left it for 10Hours one night and it made it no further.
Update, I am formatting with pocket mechanic now, Fat 32 4k cluster Low level, Backup Fat
Update2 Well format failed, now the card cannot be read by the OS, I am going to RMA the card. Guess that will fix it
1. I have encountered the same problem and rectified with an SD reader. My SD reader works for SDHC 8GB card. So perhaps if you can find an SD card reader, try it.
2. As for formatting with pocket mechanic, it doesn't seem to work for me as well. What I did was to use error correction in Win XP using the SD card reader. This worked for me.
3. You could also try downloading some usb host software bypassing ActiveSync totally and use your 8GB card like a regular flash/thumb drive which should dramatically improve your file transfer time.
I bought a Team 8Gb SDHC class 6 and the HTC freeze and work very very slowly. No obstanding, with the card readers works fine.
In memory mode (HD2) works more less (3Mb write and 6.2Mb read), but the phone works too slow. I power off the phone and change the card to the original Sandisk 2Gb and works nice.
IS there any way to fix it?
I'm assuming you tried formatting it in your PC? Maybe try using a different block size. Others have had success with this technique for various card issues. It's worth a shot.

I didn't format with the PC, I formatted with the SD format tool in HD2. I'll try from the PC.
this happened because you probably have a large music library on the sd card. the htc sense music tb hangs in large libraries

No, I have no music on it. I have some pictures (no too much), a few videos, igo 8, tomtom 7, 2 ebooks and 1 pdf.
I just copy the content from my original SD Sandisk 2Gb (included with the HD2) to the new one (8Gb). With the 2Gb works pretty fast and with the 8Gb is very very slow or sometimes it hangs.

that's the only thing i hate about my hd2. i use a 16gb card and when i hit the music tab, id have to wait 25 seconds before anything comes up. i do have a large music library with about 2500 songs. is there ANY way to keep this from occuring?
I just returned a defective sandisk 8gb SD card.. sometimes it worked sometimes it didn't.. if i worked it was veeery slow..
@oscar8x
I am having the same problem with my Team 16 gb sdhc class 6 card as well. Now I saw that you had the same problem, I am a little concerned. I formatted it using my PC but apparently that does not make much difference.
Also, I found the card rather slow not as fast as it is claimed to be. What do you think?
I would be really happy if there is solution to make it work. I can't get past entering the PIN phase.

I think it's a fake class 6 card, but I gonna try it on another phone (N97 mini) and I'll see how it works. I'll post que results
Try formatting it in FAT 32 but block size should be 4096 - use windows 7 to format card

Delete "Application Data" folder on the sd and let the device rebuild a brand new one.
I had a similar problem with a kingston 16gb, solved in this way

Yes, that was the problem. I formatted the card and I copied all folder excluding "Application Data" and it's working right now.

Hi all,
I have a SDHC 8gb (Class 4). I tested its speed with J-benchmark. Frequent test shows that the write speed of this SD isn't any better than class 2 sd card i used before(4 gb).
I usually get write speed of 1.5mb/s and read speed of 2.5mb/s. Today I decided to change the buffer size to 8kb and got 4mb/s write speed. This is what a class 4 card should normally hit right?
So, I'd like to know if there's any way i can increase the buffer speed while transfering files from my PC. I'm really having a hard time copying movie files to my sd card. Files transfer of larger than 100mb take ages and even get disrupted at times.
Thanks for the help!!!

Random no-name brand? No surprise.. Lots of cheap, slow, unstable storage cards out there these days.
J-Benchmark isn't of much use if you don't know what the real workd transfer speed is, so you might want to try testing it against the computer... Send a large file, time it, see how long before you can safely remove the device.

well, it says transcend but i'm doubtful. Bought it at very cheap price from a wholesale market.
But there's something I've noticed, the transfer speed is slow through usb only...if i unmount the card and use it through a normal card reader its quite fast...I tried sending a 800mb movie file and it took just above 4 mins....
So, I don't think its the card that's the culprit. puzzled!!! could it be the rom i'm using or froyo itself?
I'm sorry that I can't be of any help, but i got the exact same problem. Bought a 16gb card, kingston brand, class4 (don't expect that much of it, but the stock was class 2, so i figured that it would be ok..)
I get horrible write speed, around 200-250 kb/s (or whatever it's called). Don't remember what the old one did, but it wasn't that bad.
I've plugged the card directly into the PC, and it gets much higher speeds..
Exactly the same problem, as u guys..
Come on, an hour to copy a movie to the phone, that's just not acceptable!
PS: have you tried this?
Mine was allready at 128, but it's probably worth a shot..

Hope anyone has some solutions to this, it's just seriously annoying
Oh, and i've got the desire with cm7 on it, it's not that different from the n1..
It's the phone not the cards. It just doesn't appear able to acheive transfer speeds higher than you'd get with a Class 2 SD card.
In the link i posted, there was a guy who found out a way around the limits of android on a EVO 4g device. I was hoping for a similar fix.. Or just something
Bought a Class 10 Kingmax and disappointed that write speeds are still maxing at 1.5 MBps Waste of money
2.5Mbps in recovery.
SOOOOOO SLOW copying videos over yaaawn.
Using a card reader means switching off the phone, which is not really an option IMHO.
You can benefit from the faster rated cards if you use a card reader, and even better if you buy a second card so that you can load up one while using the other. Quick swap, job done!
I have a Transcent 8GB class 6. I get speeds from 6mb/s-8mb/s.
This may just be a case of me being genuinely unlucky in my purchases but humour me anyway!
Like you lot I have an SGS and with all the recent mods regarding sound I like to use it as my mp3 player, so buying a micro sd card for additional storage was a must.
I had a spare 4gb class 2 card lying around so I've been using that for some months. Finally decided to upgrade to a more meaningful 16gb class 4 card.
Ordered one off Amazon through a seller. As soon as I put the card in the phone, it refused to recognise it but my PC, digital camera, old blackberry 9000 and n95 saw it just fine. So I formatted the card in the pc using the downloadable SD Card formatter as some googling suggested this might return the card to a working state. After that the phone saw a 16gb card, so I copied some music onto it, it worked for about 30 mins and then the card died totally. Upon reinserting it into the pc, windows only saw an 8mb card in RAW format and nothing I've done since has recovered the card. Card was dead.
Anyway I contacted the seller who posted me a nice shiny Kingson 16gb class 6 card right away.
New card arrived last night, appeared in the phone straight away as a 16gb card. Great start.
Plugged the phone in, started copying some music on it - the write speed was incredibly slow. I mean really slow, 100mb of mp3s was taking the best part of 3 minutes. Popped the card in the PC, same problem.
I find that I can actually write data to the card till its full (albeit slowly) but once you've written more than around 4gb of data, the files start to vanish.
I know it sounds incredibly stupid but anything written after around the 4gb mark just doesn't appear when I plug it into the phone or the PC. The card claims it is full, but only 4gb of data is visible, let alone accessible. I've done the usual formatting of the card and changing card readers etc etc but the result is the same and this is starting to grow boring.
So, question. Am I just incredibly unlucky in my purchases or is my SGS killing cards? Because I'm quite weary of buying yet another card now.
Funny enough my old 4gb card still works just fine like it has for years.
I know you'll have a FAT (file allocation table) that usually reserves a predetermined amount of space on the card for file locations. But your memory card should not be able to accept more than whats available and should be displayed correctly no matter what your using. IE pc or phone. Kingston are fairly reputable, but is your dealer reputable. There are a lot of counterfeits out there. I don't believe the phone itself is damaging these cards. Since your stating your old trusty card still works like a champ
Sent from my GT-I9000M using XDA App
I know it has been asked a lot in the past, but searching didn't provide Milestone specific answer.
So If I buy Class 6 or Class 10, will the milestone be able to utilize the full write speed? I am running Cyanogenmod 7 RC0 (latest). At the moment I have 8GB class 4 Apacer microSD and tbh its a terrible card. All I get is 2.5 mb/s write on large files, but I am getting the same speed when the card is in card reader too so its not phone issue.
Thanks.
Maybe I'm wrong, but what I know is that the card class is the limit. It doesn't mean it will read/write at full speed all the time.
How are you testing your speeds?
Maybe SD Speed Increase help you.
https://play.google.com/store/apps/...t=W251bGwsMSwxLDEsImNvbS5zZGluY3JlYXNlLml0Il0.
I don't know how to test my speeds, but were getting 24mb/s read and 8mb/s write speeds in SD Tools ( https://play.google.com/store/apps/...1bGwsMSwxLDEsImFsZXMudmVsdXNjZWsuc2R0b29scyJd ). I'm using a Samsung 16gb Class2. I think the app is not calculating very well. Don't know.
I am using the SD card as USB mass storage instead of carrying separate thumb drive. I transfer a lot of large 1+ GB files.
I tried SD Speed increase last week and it does make a difference on smaller files, but when copying 2GB files it seems to start fast (like a burst mode), but if timed it takes exactly the same time to write something on the card.
I am going to change my 8GB card for 16GB today anyway I just wondered if class 10 is worth getting or should I get class 6 and save some money. Whatever I buy I will report back and test the speed.
I went ahead and bought Patriot LX 16 GB class 10 microSD. Now I get variable speeds from 3.5 mb/s to 8 mb/s depending on the file sizes. As I read somewhere this is due to fact that the phone is using MTP protocol to act as mass storage device.
Anyway with the old card I was topping only 2.5 mb/s no matter the file size, so it's definitely an upgrade and since class 6 was only 5$ cheaper I saw no reason not to buy the faster one, even if the milestone can't utilize its full capability. In the end its an old phone and I believe there weren't any class 10 cards out in 2009 anyway.
And one more thing, the camcorder isnt lagging anymore when recording videos
EDIT: After booting in recovery and clearing dalvik and cache partition I am getting 9.5 + mb/s, but it does start around 4.5 mb/s and then rises to its full speed. Cheers.
Except for the improvements in video recording, is there anything else that runs smoother for you when using the phone?

I think everytime any app need to access your sd, it will be smoother, like gallery, taking photos, loading maps cached in sd, music apps indexing songs, etc. Accessing apps installed on sd card may be loaded faster too.

Thats right. Gallery loads faster, applications and games moved to SD start up faster etc. Don't know about maps, but I suppose they cache faster too.
However the main difference is when copying stuff to phone in mass storage mode. Thats why I got a higher class card in first place. While all other stuff related to reading from SD do seem snappier, the difference is not all that great since even Class 2 cards can read with high speed, but when it comes to apps that are writing the difference is obvious.
I'm using a Samsung Essentials 32GB Class 10 Card.
Gave me some troubles at first, something with sector sizes seemed wrong - but after formatting it with this tool https://www.sdcard.org/downloads/formatter_3/ it worked.
Someone in these forums suggested the tools - search for the link to find the recommended settings.
Alright, thx for the answer. For someone not using the phone the same way as you, do you think it would be worth the money to get a faster card?

The difference between class 6 and class 10 right now is only few bucks. I don't see why not. You never know, may come in handy.

16GB microSDHC CARD Class 6 - Transcend

I wouldn't go below class 6 since the camera is lagging when recording videos.
Is it true that if a formatted microSD often will make it slow microSD?
It' unlikely, but possible.
My Samsung Essentials 32GB Class 10 card gave my Milestone hiccups at first (rebooted several times when powering on, rebooted every time I left USB mass storage mode) so I re-formatted it using these instructions: http://forum.xda-developers.com/showpost.php?p=23494134&postcount=7417
Now everything works fine and I still get a little more than 10MB/s when copying movies via USB - so no loss here.
