'[EE] USB drive emergency'

My new flash drive just died and I desperately need data off of it, as  it's been almost a week since my last backup with a lot of work done  since then.

I really suspect the connector as it's a bit bent.  When plugged in,  it either is not detected at all, or if I put pressure on the  connector it will detect something, then come up with "One of the USB  devices is not recognized...".

It's a USB 3.0 drive (9-pin connector), but my computer has 4-pin USB  ports.  I've opened up the flash drive and the connector has "110815",  which I've not yet been able to find.  But it looks identical to  Amphenol GSB316441CEU (datasheet...  http://media.digikey.com/pdf/Data%20Sheets/Amphenol%20PDFs/GSB316431CEU.pdf )  or Wurth 692112030100 (datasheet...  http://katalog.we-online.de/kataloge/eican/media/pdf/692112030100.pdf )

I'm stripping a generic USB cable and intend to solder the 4 wires to  the appropriate pads on the flash-drive PCB, but am not clear which  pins on the USB side are mapped to which SMD pins on the PCB side,  because the Amphenol connector does not show pin numbers, though the  Wurth does.  I'm testing with an ohmmeter, but so far all I see is  that USB pin 1 maps to the second SMD pin, and that matches the Wurth  connector datasheet.

Would it be safe to assume that these connectors (including the once I  have) have the same mappings?  And anything I need to do with the  shield wire?

Before I cause more damage, thoughts appreciated.

Cheers,
-Neil.

I've had some luck with just reflowing the solder between the board and connector on USB drives.
I've also had luck moving the memory chip over to an identical working USB drive (thumbdrive that is)

Actually just tried that, but still not ohmmeter not seeing any  connection to 2 pins.  There are 2 large chips which have no visible  pins, so I won't be able to move them.

Just soldered on the wires, so my next email will be either extremely  happiness or extremely sad...

"Device not recognized" generally means Windows knows there's a device
there due to the pullup resistors, but the hardware is not
communicating.
I'd reflow the joints like others have mentioned.

Mixed results:  it worked for a bit... I instantly started copying  files but it died after some time (maybe 20 mins), and the drive was  not recognizable anymore after that.  The drive was hot at that point.    I'm at home today so all I have is a basic weller iron, but I can't  see anything that looks shorted.

Good news is that I got my Eagle files back (lots of work there).   Average news is that I could not get some invoices/admin stuff, but  since I emailed those to customers, I can extract from emails and  re-create.  Bad news is that I could not get back all but one PIC code  file which was last modified on Saturday.  It's not enough for me to  bother to go to a data-recovery service, so got some work to do again.  :(

Cheers,
-Neil.

Neil,
you have one "enclosure" and one harddisk.
I understand that the enclosure is bad not the harddisk.
The harddisk is not USB3 but only SATA(1 or 2 or 3) so you can connect to a motherboard or to another enclosure SATA compliant.
;-)

If it's hot that's not right.  Have you tried giving it a half hour to
cool back down and then try inserting it again?

I've got these great canned air things at work that if you flip them
upside down you get a very cold liquid- I'd shoot it with that as soon
as it started getting hot if your copy operation isn't complete yet.

Not hard drive, but flash drive.

BTW, as of a couple months ago, I've been shuffling between 3  computers and data-syncing has been tedious (and one is a netbook in  my car's glove box so don't want to leave any data on it).  So I got a  32GB flash drive for my active & personal data and all machines have  apps installed and more static data (datasheets, etc).  Worked well  for over a month, until today's failure.  And of course it happens  when I miss one backup.

Cheers,
-Neil.

Yep, tried it a couple times after cooling.  It definitely won't  recognize it now, and some components get quite hot within 10 secs of  plugging it in again.  I'm not too worried at this point.

I know that we've (the PIClist) had this discussion previously, but I should mention it again: both Dropbox and Sugar Sync work EXTREMELY well for keeping files synchronized between several different machines.

Dropbox offers a 2GB account for free, Sugar Sync offers a 5GB account for free.  Sugar Sync also costs about half of what Dropbox charges for a yearly account.

I use both.  My free Dropbox account handles all of my PIC and CAD stuff, as well as all the little miscellaneous stuff that I tend to gather.  Sugar Sync (30GB account) has all of my ebooks and magazines (about 20GB so far) as well as my Windows Utils install-files directory (several GB).

Shameless plug: use my referral link to sign up and both you and I get extra space for free.  This free space is perpetual - it never expires or needs any payment - ever.

Dropbox referral link <http://db.tt/8nh08je>
SugarSync referral link <https://www.sugarsync.com/referral?rf=csq0xyf24f4tc>

One final advantage (for me): both Dropbox and Sugar Sync maintain a complete copy of that data 'in the cloud'.  That means that I can access it anywhere I can get an Internet connection.  Obviously, I use very strong passwords for those accounts so as to minimize risk of data snooping.  I mention this because there are those folks who can not tolerate the risk of a third party holding a copy of sensitive data..

Neil: you could use one of those services and still keep a copy synchronized to your flash drive.  If the drive ever dies like your previous drive did, you would still have access to those files.

Install TrueCrypt on it. I use and it is very secure and efficient:

Unfortunately, online/network-based/cloud type models don't fit my  lifestyle right now.  Since my dad passed away a couple years ago I've  been *very* displaced and fighting major legal battles out of the  country.  I get a lot of coding and admin stuff (ie: computer stuff)  done when I'm on airplanes and when I'm in a third world country,  which are the times I have very poor or no internet access.

Even here in the US, depending on where I am at any given time,  internet access can be quite crappy, so I don't want to depend on that  right now.

Cheers,
-Neil.

I've been using AxCrypt, which works fine, but I'll investigate this.   One thing I'd like is the ability to password protect a folder in one  shot, rather than each file individually (and without zipping, etc).   If I double-click on an axcrypt'ed file, it asks for a password and  will open it up in the correct app, but if I open up MPLAB and open a  project, it won't recognize or open up the individual project files  (unless first decrypted and then re-encrypted after I'm done).

Would be nice if Truecrypt could handle that easier, or if it let's me  unlock a folder first, then be able to handle this until I lock it  again.

Cheers,
-Neil.

Same here. And also I'll mention Unison for syncing between drives.

With TrueCrypt you can have a file that becomes a drive letter when
mounted. If the unit is not mounted, you can backup the file and its
whole content is encrypted (and it is impossible to tell it is a
TrueCrypt container). When mounted, its contents are accessed through
the drive letter as if it were really there.

You can also encrypt an entire partition, whose contents become readable
only if the partition is mounted via TrueCrypt.

The third option is to encrypt the entire drive, where the only
unencrypted portion is TrueCrypt's bootloader. You can boot the system
only after entering the passphrase. It is not possible to tell even the
operating system that you use without mounting it first.

You said it got extremely hot - put it in the fridge for a while, then try for the next bunch of files.

Truecrypt works on a "container" basis. It shows up as a new drive
letter.

The container can be ANYTHING. Usually it's a file on your main drive.
It can as easily be a partition on your drive, or a whole flash drive.

A container can even be hidden in another truecrypt container, making it
almost impossible to know it's there.

Once you "mount" the container (after entering your password) the
encrypted volume is just another drive letter (or mount point if using a
*nix based system).
