Post subject:  USB Flash storage device problem.
Hello. I have flash drive and i dont know who made it =)
It was present from company. First problem was that cant put there more than 300MB... flash drive is on 15GB... i tyrd to wipe it using HDD LLF Low Level Format Tool. i was in a hurry so i leave it to format. After i came back PC was turned off and i dont know what was there... is it finished or not or what.
After that when i insert flash in PC, Windows want to format it, but he cant because its Write-Protected (i dont know why and how). All this was week ago.
Today i tryd to wipe it again and it gives me nothing. Here is log from HDDLLF http://pastebin.com/9C9wcegG

I dont know what to do to make it works... maybe some one can help me...

Thank you.

Use ChipEasy to find the controller then look for the MPTool for that controller, it will reload the firmware and low level format the media based on the NAND chip's actual capacity.

After chipeasy, take it apart and have a look inside. I think it may not have a regular nand flash, but a serial eeprom. it will look like probably a blob with few traces.
or it is a 512MB chip only with some alcor based dodginess reporting the wrong amount.

If it was from a company with marketing material, this makes sense.

if it was " here, have a nice flash drive" I would be suspicious of it.

Well ok. Here is what i have. I attached couple files.
I make foto of USB flash from bouth side... and good foto of chip with all marks
and screenshots from tools i used.
Chipeasy gives some information (hope so)
MP tool gives nothing...
In QC Tool (bouth version 1.0.2.8 and 1.0.2.9) u can see that there is firs divce seems active. If i press that 1 there apears menu with not activ buttons Start Stop Refresh.

Gift was like " here, have a nice flash drive" because he gives me two of them and one works fine. Second not :/ And man who gives me flash drive use them by himself

if you don't need data then I would not do anything with it... you could never trust it

Totally agree, I would trust it as far as I could throw a rhinoceros.

It's almost certainly a "Frankenstein" device made from broken/refurbished bits.

agree, a NAND chip with no branding is like a built in dodgy alert, and a flash device with no branding is the same usually.

Another thing - those wider TSOP48's. I'm not sure what the deal is with them, I haven't seen them in anything but flash drives that commonly always have wildly different components - usually refurbished. Out of my 400 -500 research flash devices that are TSOPs, I have 5 of these wide ones. None of them have a manufacturer name, but all have part numbers.. the part numbers are fairly strange. not really sure what these are and why they made them a touch bigger than a regular TSOP.
