Alright, here we are...

I went ahead and posted a photo of the back of the card though it's not particularly legible. Hope these help...

Thanks for the pictures and I'm sorry to hear about your problem... That error notification was the same one I was getting... Try this, connect your phone to your pc via the usb cable provided and set the phone to mass storage mode (I'm gonna assume you know how to do that or that you can figure it out). The card should be browseable as a drive when you do that. If it shows up as a drive but then informs you that no drive is present when you try to access it then you are experiencing the exact same thing as me. Unplug the phone and try to format the card in the phone. If nothing happens and the error just keeps showing you have a corrupted or f*cked card just like me.

Please try that and then report back here... Seeing your card actually makes me think that it's the same one I saw in my phone... That would actually make much more sense if that was the case. Both of us got some crappy no name class 2 card that crapped the bed.

Yep- that's exactly it. I'm getting a bit of a run-around about it. The store pointed me to Verizon customer service, who in turn pointed me to Sandisk, who in turn pointed me right back to Verizon (and rightfully so) since it's not a Sandisk card. Verizon tech support stands by the assertion that Motorola is equipping all X's with Sandisk cards, so Sandisk has offered to look at photos of the card to be extra certain it's not their card (and, to be fair, if it were a Sandisk card, I don't think I'd be having this conversation right now).

The Verizon rep assured me they'll take care of it if Sandisk comes back and says it's not their card, but it's going to be several days before I hear anything. I was shopping cards this afternoon, and I think I may just go out and snag a PNY 16gb class II card for $60 and be done with it. When Sandisk comes back and says it's not their card, I'll just ask Verizon to put a credit on my bill or something. <shrug>

THE FOLLOWING IS A DISCUSSION OF HOW TO GET VERIZON TO REPLACE A DEFECTIVE CARD WITH LESS OF A FIGHT.... HOPEFULLY. IT IS OFF TOPIC AND I APOLOGIZE. UNLESS YOU HAVE A DEFECTIVE CARD, FEEL FREE TO SKIP THIS POST AND CONTINUE WITH THE TOPIC AT HAND.

I'm sorry to hear about the run around they're giving you. I can't pretend to know how you're approaching this when you're talking to them but I can tell you what I did and what worked for me. (keep in mind, you will probably just come out of this with a class 2 Sandisk or whatever is stuck in one of the other dx's in the store):

It's important to remember that you are entitled to having this corrected quickly and without trouble: you paid for properly working hardware, not the chance that it would function correctly. Thus, you really aren't asking them to do this; you are politely explaining what you expect from them

I called a verizon store near me and quickly began explaining my problem without really letting them get a word in edge wise. I explained that the card had become corrupted, explained how I knew this and told them that based on my research online this type of thing does happen. Next I informed them that the typical resolution involved the nearest verizon retailer replacing by the card after verifying that the card in question was indeed corrupted.

I'd then follow up by saying that you'd like to stop by and have them verify what you've said by looking at the way the card reacts in the phone and then seeing how one of their cards works (this is what they did for me).

By doing this I, let them know that I knew exactly what I was talking about, and they could also tell I had done my homework on this specific issue. I also provided them with the next steps to take so that they didn't have to come up with that themselves, and they also knew what I expected of them.

If they try to redirect you, politely say you understand why they may not be able to help you themselves so you'd like to soak with their supervisor or manager. Keep moving up the chain while using catch phrases like "superior service" (ie mentioning that you know verizon is committed to superior service but that at this time you don't feel like you are receiving superior service).

Don't even bring the card brand or where you bought your phone into it. This is a matter of verizon equipment not performing as advertised and it needs to be taken care of by verizon.

There are, many many other issues at play here but if I go there, this is going to turn into a discussion of quality control, deceitful manufacturing and sales procedures and poor customer service (all of which are valid discussions, but not in this particular thread).

The Droid X is totted as recording 720p, from what I understand, a class 4 card is REQUIRED to record at 720p (class 2 is supposedly too slow), so ALL new X's should come with one, if not I would contact Verizon and find out whats up.

Not true. I've taken a few 720p videos and all have averaged under 1MB/s. IIRC user Crane reported the same in another thread talking about SD class speed. A class 2 card is plenty fast to support 720p video recording.

Another thing to consider is that class 2 (2 MB/s) is the minimum write speed rating. A class 2 card may have much faster write speeds, just not guaranteed. My 32GB SanDisk microsd class 2 actually tests at 5.37 MB/s write speed.

For the OP, my release day Droid X (ordered directly from Verizon) came with a SanDisk class 2, which I promptly upgraded to a larger card (32GB still only readily available in class 2).

Edit: see this thread for existing benchmarks http://androidforums.com/accessories-droid-x/129481-sandisk-32gb-speeds.html

My phone was just shipped earlier this evening. I will post here with my findings when it arrives, (should be sometime tomorrow [it's currently 11:45PM]).

EDIT: I do not know how accurate this is, or if there are others, but I just now found this application while reviewing my AppBrain list.

1st phone had a generic class 4.
2nd had a Sandisk class 4
3rd has a Sandisk class 2

Needless to say I held onto the class 4...

That's the first Sandisk class 4 I've heard about... I can't blame you for keeping that one. That's not a cheap card by any stretch of the imagination!

SD Card Speed Tester - Android app on AppBrain

I'll go give that app a try, thanks for that. I haven't gotten a chance to try out the other benchmarks yet.

Delivering, as promised.

EDIT: I don't think the application that I linked to is very reliable. At least, not with the DX and/or these cards. I inserted my old 8GB micro SD card that I got shortly after getting my LG Voyager in 2008 and here are the results.

SD Card Speed Tester said:
Write speed is: 10.0MB/s
Reading speed is 14.0MB/s

Measures suggest your card is a Class10 Card.

Card speeds are identified by classes, the biggest the class, the fastest the card.

Basically the class inticates the minimum transfer rate the card supports.

Existent classes on the market are:
- Class 2 - Minimum rate of 2MB/s
- Class 4 - Minimum rate of 4MB/s
- Class 6 - Minimum rate of 6MB/s

Observation 01: If your test suggests your card is a Class 6 but your card is a Class 2, notice that Class 2 indicates MINIMUM write speed, in this case, it could be faster but not slower than 2MB/s.

Observation 02: Don't run this test if another application is reading from or writing to the SD Card because it will affect results

Either the application is screwed up, or the test that I ran simply didn't go very well. I only ran one test with that card.

Here are my results with my 16GB SD card that is shown in the first picture above.

Card came with phone on launch day micrSD japan 4

If you look at the phone spec sheet I believe it says it comes with a class 4. So if i was you I'd dig that up and make them give you a class 4. Oh and I don't for a minute believe the person you called had your card in front for them.

I highly doubt that the card class is listed: it completely contradicts what we've seen from Verizon/Motorola and every other company that deals in similar products. The ideology seems to be something along the lines of
"Toss in random parts that most people won't notice and make NO notes that we're doing this. When someone does notice, deny, deny, deny until they can prove something."

I will take a look, but I'd bet a years salary it just says "16GB microSD".

The reason that I DO believe the person had my card is b/c, #1 they were actually very willing to help when I went in the first time and #2 one of the users above also had a class 2 nameless 16GB card that has been corrupted. The odds seem pretty good that he had the same card as me.

I ran the benchmark program (SD Card Speed Tester) and my class 2 Sandisk returned a Write Speed of 6 and Read Speed of 13. My brothers class 4 unmarked (but found to be Toshiba manufactured) card returned results of Write Speed = 7 and Read Speed = 12.

The only reason that I actually believe these results is that someone (can't recall where) posted that they tested their cards with this app and also the tradition connected-to-computer way and both returned the same results.

If you're getting weird results, I recommend you try H2testw. It comes highly recommended, and takes the Droid X out of the picture (you run the test on a PC). In addition to speed tests, it'll also help you test for counterfeit flash memory.

Then the issue of USB speed comes into play. My computer is a shitbox and I trust my device to test the card better than my computer and its slow-arse ports. Thanks for the recommendation though.
