Sata Hdd case auto disconnects

**skarosg3** · September 21st, 2012

Hi all,
I have a small problem. i got a case for my old 2.5' sata hdd, but when i connect it to my 11.04 I am getting this on system log:

Code:

any ideas what the problem might be and how to fix it.

I have tried it on my win7 netbook and it seems to be working fine.

thanks, ilias

Does your drive mount? I'm having a problem with a disk that works internally but when connected through a SATA-USB adapter it only works for a few seconds to minutes before consistently reporting errors. I won't threadjack with my specifics if your problem is very different. What have you tried to debug or work around this problem?

I've made a bit of progress. Following the replies in https://bugs.launchpad.net/ubuntu/+s...x/+bug/1012291 I installed a mainline kernel (hardest step is working out which you need). My disconnect doesn't reproduce as consistently after a switched from "3.2.0-30-generic #48-Ubuntu" to "3.2.27-030227-generic #201208101235" which is a mixed blessing. I also found https://wiki.ubuntu.com/Kernel/Debugging/USB which shows more details but needs someone more familiar with USB to make any sense of it.

Hi tomgobravo
thanks for your info.
i will see if your solution works with my problem.
I got a new problem now though. i will ask it here in case someone migh help me.

while i was copying some files to the external drive, it crashed, and it crashed big time! i had to fore restart it, resulting damaging my internal ntfs drive. For some reason, it changed the file system from ntfs to RAW!! now i cant even use check disk under windows! any idea?
under ubuntu i cant mount, using gparted i see it as empty, and under windows it tells me that the drive needs formating!

I guess it is a lost cause, and needs to format it in order to make it working, if that would fix anything and i wont have to get a new drive!

Before doing anything drastic take a look at testdisk http://www.cgsecurity.org/wiki/TestDisk

It might be able to recover the partition table for you.

It can be installed and run from a LiveCD and testdisk is in the repo's.

If it does work then we can sort the other issue.

Thanks for the tip, i tried this, but i am not sure what to do next.
I got to the point where it is doing the quick search, but at the end of it all i was getting was this:

Code:

Disk /dev/sdb - 500 GB / 465 GiB - CHS 60802 255 63
     Partition               Start        End    Size in sectors


Keys A: add partition, L: load backup, Enter: to continue

do you know what A and L do?
I chose to continue and now i am doing a deeper search, but i think that i will stop it and redo it tomorrow from scratch, it is getting late, the quick search took more than 2 hours to finish, now with deeper search who knows.

if you could tell me what the other two options do, i might give it a try tomorrow.

thanks though. it seems that the drive is cooked, but the program is good.

edit:
for some reason the log file was updated after i made my choice. this is from the log file:

Code:

search_part()
