Subject description: MY flash drive randomly unmounts and remounts with a diffrerent drive letter.
 

MY flash drive randomly unmounts and remounts with a diffrerent drive letter. It annoys me very much, and if it were not for WGET --continue I would lose a lot of work/time. WTF it just did it a s I type, but when running FSCK to see if it was corrupted hopefully it didnt just kill my files LOL.I dont know whats wrong with it Sad it never does that on Windows, but it dows on other versions of Puppy Linux but not other Distros. Maybe my USB hub I got a few months ago has something to do with it, but again it works fine on Windows. I do constantly read/write to it (HUGE Minecraft and Minetest maps, occasionally run LAN server) maybe it causes some sort of MFT damage because the HUB lags sending data? I cannot see why because it is rated 200 Million+ write cycles and has auto sector relocation/redirection built into it. I donmt remember the exact model chips used but I know they are Transcend JetFlash2 NAND flash array. ITs a 2 chips array kindof like RAID but propitery, has no OS requirements for its features and appears as a a normal drive. Anyone know? It never used to do this, maybe the contacts need cleaning?

EDIT: Forgot to mention, Puppy Linux crashes shortly after unless I am quick to remount it as /mnt/home because its the boot disk. ITs capacity is 32GB with redundancy and 64GB with striped storage mode (depending on if a jumper is installed or not while formatting). I did make this flash storage device, and I know its not the drive's firmware because I already debugged that. It used to work perfectly, it still does on windows and other Linuxes. The hub is a Linksys 4 port ultra high speed USB 2.0 hub.

I'm not sure what you mean about "unmounts and remounts with a different drive letter", since on Linux we have "mount points" instead of drive letters.
And if you had it remount with a different mountpoint, you would need to change directories afterwards...

First thing to do is make sure everything is clean, and check that the USB hub is plugged in properly/has fully charged batteries.

Second thing would be to save the kernel messages immediately after it flakes out:
Code:
dmesg | tail -n 100 > usb-err.log

Post usb-err.log and I may be able to figure it out.

PostPosted: Sat 23 Nov 2013, 15:38    Post subject: Problem with checking it.  

I tried to, but Puppy Linux crashed before I could. Like I said it IS the boot drive and I dont have any SFS files loaded into RAM so it kernel panics about 10 seconds after the drive glitches. When I say it remounts with a different letter I mean the icon on the desktop will be sdc1 and it remounts as sdd1 for no reason. Sometimes it quickly remounts as sde1 nad sdf1 again before crashing but not usually. It would be no problem if Puppy Linux released /DEV/SDX# after unmounting as it would remount with the same letter. Basically it does the same thing as if you boot a hard install of ubuntu off a USB hdd and quickly unplug and plug it back in. It mounts with a different letter and the kernel loses access to the OS drive so it freaks out and crashes. Not the normal blinking caps lock and num lock, all lights on my KB blink (function lock, caps lock, num lock, scroll lock) its very strange. Maybe I should redownload the iso and extracta a new copy of the kernel, initrd and main SFS. I have no idea otherwise.I stress tested the hub by streaming video @20MBits on each port on Windows and it never lost connection to any of the four screens I had connected via usb.


I booted off a different usb and tried getting the kernel messages so it would only be a regulat drive dismounting. here is what it said.
Also it wasnt in the last 100 lines becaus I have debug set to high so that part was already past 100 lines ago.
$dmesg | tail -n 100 > usb-err.log
Here is a full simplified version of it, it seems to simply reconnect with no error as if a pulled it out and plugged it back in.

Code:

SDB1 is the boot drive and SDC is what the troublesome drive started as
Ignore the message about SDB1 being incorrectly unmounted, I pulled it from a Windows PC that did not have quick removal enabled last time. I didnt know that untill windows said unabled to read $MFT. That is not the drive in question and has no problems, even though I will FSCK it to make sure it dosent have problems in the future.


EDIT: Happened agasin, this thime the error is clearly shown.

It appears to be some kind of unhandled hardware exception/error.


I can reproduce this error as many times as I want by writing a huge stream of data to the drive. After typing $cat /dev/urandom > /mnt/sde/random.data it fails ithin seconds. Maybe the flash menory really is going bad or the controller chip on the drive is. I will repeat this to see if I get consistant results.

Yep, every time,, now I have a predictable error, I will see what you think of the kernel messages, because I cant make anything of them other than a unhandled error that the driver is unable to recover from. HAs something to do with being unable to flush the cache to disk.

I can write data from urandom to any other drive, even ones plugged into the hub without a error, clearly the Flash drive is to blame, and Windows must handle the error better than Linux for some reason. Funny Windows is able to recover from a error better than Linux, thats a first LOL.

PostPosted: Sat 23 Nov 2013, 23:40    Post subject: Trying my "Fix"  

Im gonna try fixing it my way, the way I fixed a different drive.
echo /dev/zero > /dev/sdc it to the end of the drive, and create a new partition table, than format it with a Windows setup (long format). That fixed the last drive I had go glitchy two years ago, why wont it work for this. I backed everything up, here goes nothing! (cant hurt anything if its already broke LOL)

Also I got a signature, It makes me LOL every time I read it.

Didnt completely fix it, it marked half of the blocks bad when formatting :O Now it works, but everything gets fragmented because its trying to avoid the bad blocks LOL. I just getting a new drive, I could build myself a 1TB one now for $128 with how cheap 32GB flash NANDs are these days. Im just gonna build a new flash drive or buy a premade one.
