[Q] Used Nexus One, Rooted, Cannot Get SD to work or Computer to recognize

So I bought a used nexus one, att 3g running cyanogen and am having issues. I am a total noob, fyi. The phone does not recognize my 1GB or 8GB SD card, and my computer wont recognize the phone. I do not have the sd card that the previous owner used so I have no recovery image or ROMs to flash. Can someone help?

Perhaps you have developer mode on.
I need you to go to Settings > Applications > Development
If you have USB debugging checked, uncheck it.
If it is not checked, then what I say is not you solution. As a last resort, you might consider grabbing a cheap card reader that you can insert your sd card into which connects to your computer via USB.

Thanks aeronex.
I tried that; no success. I was thinking the card reader may work, so i will try that. I didn't expect this when I bought the phone, but it seems that with android there is almost always a solution.
I';m betting someone who reads this will know.

When you say won't recognize, do you mean not even the Pop up in Windows that says a New Device and searching for drivers? Try downloading and installing PDANet for USB tethering to get the drivers.
As for the card under Settings>SD Card & phones storage settings is Unmounted Grayed out or in White Print?

The option is grey. It won't allow. I will try the pdanet drivers now

No luck with PDAnet. Windows 7 still say "Unrecognized device drivers not installed". I have downloaded SDK and tried to manually install the drivers as well; no success.
So to recap the option of mountign SD card is grey, not white. I have even booted into recovery but cannot mount SD card that way or format SD card that way.

[Q] Error installing app Can not install USB storage or SD card

I recently updated my external SD card.
Transfered all the information from the old one to the new one, VIA Windows PC.
Seems like all went fine until I went to one program I thought was installed PPSSPP
Seeing as it wasnt showing up now I tried re-installing it.
Now with the play store it says after downloading that the app
Could not be installed on USB storage or SD card.
Looking at troubleshooting here is what I did so far.
I did look for the file smdl2tmp1 and did not find it anywhere.
Unmounted the SD and rebooted , install of PPSSPP and says same error.
Removed SD and booted , still same error on install.
Dirty Flash Rom.
loaded Rom Toolbox lite and changed app2sd location.
Same error on everything I tried.
The only thing I can come up with is that there is a file that is causing problems that I cannot find where it is.
Any suggestions without doing a full flash and reinstall?

Any thing to help is greatly appreciated
Update tried downloading and installing another app and getting same error , on something that I never installed before.
Update 2. Wiped SD internal and external , did not work. Same error

are you sure the SD card is not fake? for years now, ebay fradulent sellers peddle 4gb cards with a 32gb filesystem. After going over 4gb, the files are just copied to dev/null, but their names are still present in the allocation table
so plug your card to a computer and check it with any flashdrive utility

If you are unable to write in the external sdcard using a file manager too then - back up external card's data, connect to windows pc in usb mass storage mode and format it in fat32 format.
It should fix the issue.

This happened with the origional 32 GB card, then I did put a FAT32 64 GB card in the phone. Moved data over to new card.
It reads in windows fine. and both are fat 32.
Also tried installing without card installed and gave same error.
Titanium backup files will not reload, and even some amazon ones wont, but updates do most of the time.
Another thing I noticed is that my internal is GB for apps, that has about 300 MB left. I think this may have something to do with it so moved data over to SD.
Just tested about 3 restarts and finally went with a paid app, Tried changing default install to auto , internal and SD. didtn really make a difference.

"SD Card safe to remove" "Preparing SD card" over and over again.

Hi fellows, sorry to bother you i always try to manage to solve all problems on my own (researching) but there no info on the subject.
A bit of history: im the happy owner of an MT7-L09 since last month. I bought it with a Sandisk Ultra 32gb micro sd class10. I've been using the phone without any problems. Didnt even tried to root it.
What i actually did was to set up the SD card as a the default memory location. I dont actually really know what this does apart from saving all media in the SD (mainly google play music, photos and videos i shoot with the camera, some big obb files, etc).
Last week i downloaded oficial Lollipop 5.1.1 release and did a manual update. All good, i kept on using it without any problems (aside from considerably lower battery life) for a couple of days.
Then i decided to gain root access. I followed this steps after googling for help.
I gained root access but after this, it keeps looping between "sd card safe to remove" and "preparing sd card" as long as my sd card is in its slot.
After that i:
Got SD card out, used a PC to backup contents (no damages), gave it a quick format in windows fat32, then format in android. PROBLEM WAS STILL THERE
Then i went back to the pc and gave the card a slow full fat32 format, then format again in andoird. PROBLEM STILL HERE
I also recently bought an action cam with the same SD model. Got that one out and placed it straight into the phone replacing the other. SAME TYPE of SD HERE, SAME MODEL. PROBLEM PERSISTS.
I think it might be related to flashing a recovery or something like that while i had my sd card as default memory location. I really dont know what to do to ger it read any of my SD cards again.
Shall i flash original kit kat firmware again? maybe 5.1.1 again and loose root access? I couldnt find any information regarding this issue rather than try another SD card which i already did (the problem surfaced after the process of gaining root access).
Any clues?
Thaks

I just started having this problem today. I have been on the official 5.1.1 since it launched and never came across any issue until this morning. I never ever rooted or flashed anything custom and the boot loader is still locked.
As of today I started having this issue, looping between "SD card safe to remove" and "Preparing SD card" however I am able to access the SD Card and intervals. The SD Card works perfectly fine on any other device.
One thing I changed recently (2 days ago) is the default memory location, I set it to SD Card, so I am going to revert that setting back to Internal Memory and see if it fixes the issue. Thanks for the tip
If anyone else has come across this issue and/or knows how to fix it please help
UPDATE: I tried reverting the default location setting back to "Internal storage" and found that the setting had already reverted back automatically, presumably because the SD Card is not always available So no luck with that. I am starting to suspect it's a hardware issue!
UPDATE 2: I left the SD Card in the device and connected it to the PC in order to take a backup using HiSuite. As soon as I plugged it in the error stopped cropping up. I finished the backup, unplugged the USB and so far the "SD card safe to remove" and "Preparing SD card" did not show up again. It's been over an hour now. Yesterday I plugged in the device to my PC in order to copy some pictures so something may have happened at that point I'm suspecting.

It's been over 12 hours now so I'm guessing all it needed was to connect it to the pc again [emoji2]

Now that you mention Hi Suite, i played arround a bit with it before the error appeared. im gonna give it a shot

I've done that the root and installed the recovery and microSD goes into loop does not know what to do help ..

Mine is still steady after a few days, hope you fix yours too [emoji6]

Solved. It must be some issue caused by HiSuite. I connected, made full backup, safely extracted SD from computer and problem seems to have ceased.
Thanks

I got this problem today after reflashing stock recovery.
It disappears after remove and reinsert sd card, but after a reboot problem was still there.
Now I solved checking debug usb setting, because after recovery flash it has been disabled itself.

I have this problem but with the USB storage device, I bought a new one which has two plugs, one is usb the other is micro, to transfer from laptop to phone without cables. It works on PC, it works on my husband's Huawei Mate 7, but just loops on mine. Other USB storage work fine on my phone with cable, but this new one just loops "preparing to connect" and " USB removed", even when trying to connect with cable.
All software is up to date, no modifications have been made.
Any simple ideas would be appreciated (I'm not into flashing/rooting etc!)

new device detects but can not access SD Card, any idea why?

Hello,
Its a new rooted device with android 5.1 and the SD Card slot looks good and seems intact. It realizes that i have put a SD Card into it. System Message prepare Card pops up, but nothing happens afterwards. Card is not showing up in any file explorer. I have tested the Card with a different device and it works just fine.
My guess, it is some hardware driver or software issue, since it works just fine with different device.
factory reset did not help and i can not flash any rom or firmware!
How do i fix this?

Format in your device

Corrupted my adopted SD storage during 5.1 update - is reformat my only option?

The update process hung for ages, so I restarted the device. This seems to have resulted in a corrupted sd card - which was being used as adoptable storage.
The tablet now no longer recognises that there's even an sd plugged in. If I connect it to my computer it seems like the partition table is still all there, but something fundamental has broken making it impossible to use the sd.
A brief Google seemed to suggest that, if it was even possible to recover the card, it would require reformatting. I'll do that if I have to, but I was hoping there was another option...

Most probably the update was taking long because ur sdcard isnt fast. I own a shield k1 with a 32gb extreme pro sandisk sdcard as adoptable storage full of games, the whole update took like 10min including the optimising apps part. And rebooting it midway of course corrupted its data that is encrypted specifically to your device, that's why it PC cant view its data (even the parts not corrupted). So ur best choice would be to format it.

Unfortunately, I think it must be properly dead. I tried to format it - in fact I didn't even get that far. When I went to delete the partitions in order to create and format a new one, cfdisk said the write had all worked, but, in fact, the old partitions remained intact. I tried some other software to re-partition it, but the result was the same.

no problem
use this app on windows ¨HP USB Disk Storage Format Tool v2.1.8 Español (Portable)¨
sure recover it
open with administrator
ever when i use win32diskimager , i need tu use only this program to recover all gigabites of my sd and usb memorys
sorry for my english im from spain!
good luck!!
