This is weird. That happened to me but only on my Macs because i was running Parallels. On a regular Windows machine I have no problem

Have you formatted your SD card using this program? https://www.sdcard.org/downloads/formatter_4/eula_windows/
It is what's recommended you use, and not formatting it with Windows. Not sure if that will fix your problem, but it's worth taking a look.

Yes, well that (https://www.sdcard.org/downloads/formatter_4/eula_windows/) is what I've formatted the card with AGAIN. I got very familial with this utility with the first 436 we had, along with using external card readers and all the rest.
No, though I'd love to be running this via the MAC, I didn't want to introduce another layer to this hardware / software (Uniden scanner / Sentinal software) problem, so since the beginning its been Win7 and WinXPpro.
So, last time the scanner was connected was about 3 - 4 weeks ago. Like I said, its a scanner for a non-tech / non-scanner person, so once its "working" it won't be getting updated or connected all the time - which is good for me based on the numerous problems so far. So, today we connect it up, and nothing happens right away, which I remember from the first time around, being a bad thing. After a bit the PC reports "to use this device you must first format it, would you like to do that now?" Soooooo here we go....
Format the card in an external card reader. Reconnect to PC. The PC sees the card / drive, but the software (v. 1.02) can't talk to the scanner (to clear all user data). Soooooooooo, find the database files (/mydocs/unden......) and save them out. Re-run the installer for the Sentinel software, its asks "would you like to repair....?", YES. Run that, move the database files back into the proper file path, run the "Clear user data" (scanner), re-upload the database to the scanner, and finally........ run the firmware update on the scanner.
Sooooo..... why does this card on the scanner get unreadable / corrupt in some fassion, 'all by itself' - when it has NOT been connected to a PC? All that has happened since it WAS working, is that the scanner has been used (turned ON / OFF) dozens of times.
Though there are a few features on this scanner I wish my PRS-800 had, I'm actually thankful this is NOT my scanner.
Can't wait for the next firmware update, or the next time my friend wants to update his programming, I'm sure we'll be jumping through these hoops again.

I know that on the 536 if the scanner isn't shut down properly, by turning the on/off switch to off, it can cause data on the SD card to get corrupted. Is it possible the user may be running the 426 till the batteries completely run down, causing it to not shut off correctly, or something similar to that? That's about the only reason I can think of for the card to be getting corrupted.

Also, maybe I'm not reading it exactly right, but can you not use the adapter and format/clear user data/upload your programming to it while it's in the computer, and then just stick the SD card back in the scanner? That's what I do with my back up SD card and it works great.
I purchased a BCD436HP and had the exact same problems. I connect the scanner with a USB cable, press "E" to set the scanner in "Mass Storage" mode. Windows sets up the USB connection but then complains about the MicroSD card being corrupt or needs to be formatted.
I disconnect the USB cable and the scanner is stuck and unable to read the MicroSD card.
I put the MicroSD card into a card reader. The card is fine. It connects and is readable. I use Sentinel to clear user data, put the card back in the scanner and everything is fine. However I can never connect the scanner to the PC using a USB cable or the whole scenario repeats.
I sent the BCD436HP back. Purchased a BCD536HP. Same exact problem. I tried USB cables that work with Homepatrol-1 scanner. Same problem. I tried another MicroSD card. Same problem. I tried two other computers. Same problem.
I kept the BCD536HP and have just resigned myself to using sentinel with a MicroSD card reader. I gave up on trying to use the scanner plugged directly into the PC. It works fine with the MicroSD card reader so I'll just wait until Uniden resolves this problem with a future firmware update.

"I know this may be no consultation to your problem"
I never had this Problem on mt 436............ KNOCK ON WOOD............
My Batteries last over a Week before needed recharging outside the 436.
At Home in my Living room it's plugged in via a Phone charger Wall ward.
The same ward plugs in into the Cig Lighter in the Car.
Then in my Office if I need to do some changes it plugs in my Computer running Win 7 UPS Port where I constantly switches between differed Drivers............
Without any Problems.................................... Knocking on Wood somewhere.
WOW!!!! Just when I was over my headache from yesterday reading about these things, this one pops up!
Apparently Uniden quality control is either non-existent or inconsistent.
Back for more Aspirin!

Are you having the same issues with yours, or are you able to connect yours without any problem?
.
He doesn't have one. He just likes going around and calling the new scanners headaches and criticizing Uniden. He's an idiot who thinks he's being funny.
Having the same issue w/ my 436 & Windows 7 home edition, worked fine when I first purchased & setup about a month ago, now cannot connect w/ USB cord. Wonder if windows did some update that now creating some conflict w/ the scanner??
I have a question. Does the scanner work, scan normally, immediately prior to your attempt to hook it up to the computer?
If the answer is yes then I would think that proves its not the scanner, SD card, or cable. After all if the SD card was actually corrupted as your computer says it is then the scanner wouldn't have been working would it?
I mean it needs a good working SD card to function so if its corrupted that would prevent the scanner from operating.
Unless that is, I have it totally wrong......

Yes, scanner works fine, only when I connect the USB cord to pc, then connect to scanner, select E for mass storage, same comes up in scanner display, a few seconds later pc opens up a error box USB not recognized. Went to device manager, saw where there's a yellow triangle next to one of the usb ports, click on that usb port & get an error message that states the pc has shut down the driver due to an error w/ the device. Tried uninstalling the driver and unconnect & reconnect usb cord, no luck. Tried updating driver, get a message the driver is current. Even tried removing & reinsert the micro SD card, no luck. My HP-1 connects fine.
Bottom line, some setting in either the 436 or pc has changed since last time I connected 3 weeks ago, and there's some goofey conflit happening now.

I think the key here is
"error message that states the pc has shut down the driver due to an error w/ the device. "
So that tells me that they have some more adjusting to do with the device driver to make the device respond correctly. Just my nickels worth after inflation.

Sounds like it. I had the thing go weird on me one time but then the very old laptop I'm forced to use right now was acting up in general that night. Suddenly I heard the bonk of disconnect and the DM showed a nice yellow triangle on the com port. Unplugged the USB cable from the computer and stuck it back in after a few seconds and its worked fine ever since.
No other problems for me so far. I know some people have said you don't need the drivers Uniden says you do but by any chance have you tried installing them? I'm not computer literate enough to know if that would actually help but it sounds good.
Also as you pointed out Windows is notorious for screwing things up, at least in the past. You may have a point that if it still does that it may have done it again.
I'll also grant the scanner had that update not long ago although I hope that isn't the problem. So much nicer to blame Windows as usual. LOL
Hope this gets figured out for you.

I'm going to test the scanner w/ 3 different windows pc's @ work tomorrow, hopefully that will narrow down which device. Stay tuned, will report back tomorrow.
Well if it helps it works on my 7 Ultimate and old XP laptop. The XP is older than the hills and the 7 computer a newer loaded desktop model. The CPU fan broke on it though so until I can get it fixed I've been using the laptop. Both no problems except that one night.
Hopefully one of them will work and it might give you clues as to what is different on the others if anything which might lead to a workable solution if its the computers or Windows doing it.

My therory is this issue has more to do more with windows, than the 436. The only thing that changed on my laptop from 3 weeks ago to now is a windows update, which occurs automatically about once a month.
It sure wouldn't be the first time I've seen Windows mess something up with their updates.
Just had something very interesting and weird happen.
After running the scanner in serial mode since I got it, after I'd installed the required drivers, I started running Von's Scanner Screen software.
Well tonight all of a sudden it wouldn't work nor would another program of his.
Now the even odder thing was that it was powering the scanner just fine but it wouldn't work with anything else.
So I pulled the plug on the USB and put it back in and the computer said it was new hardware and needed to install drivers for it. It went along searching then installing the same drivers a second time and guess what?
It works just fine now.
Don't know if that can be of help to anyone but its darn weird to me. I would think once installed they'd stay that way but at least for me on this XP machine they didn't.
Odd....
