IDE/SATA to USB adapter not working properly
 

Hello everyone,
I recently bought a Digitus DA - 70200 IDE/SATA to USB in order to transfer data from a somewhat old laptop disk (the laptop died).

I try to connect this drive in my pc (slack64 - 13.37 , kernel 2.6.37.6 modified generic) but it doesn't showup properly!
when i connect the USB device is identified:
and try to see the partitions with cfdisk /dev/sdm

after a few seconds of frozen terminal i get a prompt back and check dmesg again"

I can't find any info about connecting this (or similar) digitus products in linux, apart from the following in their wiki of a similar product:

seriously, is it possible that the disk is identified in filesystem level???
The disk I'm trying to access is formatted in xfs, but i somehow feel this shouldn't matter....

any clues?
thank you all for your help.

Hi there,

no, it's exactly the other way: A USB to IDE/SATA adapter. With that kind of adapters, you usually mention the host-side interface first (like USB to RS232 or IDE to Compact Flash).

The adapter is being recognized ("USB to ATA/ATAPI bridge"), then the attached drive is recognized and the standardized generic USB Mass Storage driver is used. A moment later, the drive is getting disconnected again. Unfortunately, the logs don't tell why.

No.

You're right, it shouldn't.
But there's another trail to pursue: How does the disk drive get its power? From the USB adapter?

Especially with older drives, the power supplied by a USB port (500mA max. at 5V) is often not enough.
What happens then is that the drive is recognized correctly, but when it spins up, the USB current limit is exceeded and the device is being shut down again by the USB controller. I've had that several times.
You might try operating the drive with an extra power source.

hello doc_CPU,
the DA-70200 modem has an external PSU that can powerup any connected drive. the pictures should give you an idea

so it can't be that.
do you have this adapter?
if yes, have you managed to connect it?

Thank you

Hi there,

yes, I agree. After all, it was just a guess.

No, and I'm not using slackware either. But I have two or three different USB/IDE and USB/SATA adapters, and they work fine with my Linux and Windows PCs. And I see no reason for that digitus adapter not to work with your configuration. Maybe you can check it by attaching another disk drive that is known to work, so you know the adapter itself works with your system.
However, it's recognized correctly by the system, the logs are plausible at least for the moment the unit is attached.

Maybe I'd have a clue if I had all the stuff on my own table, but from the distance, I'm running out of ideas.

Hi,

That device looks like an upgraded version of the no-name adapter that I've used for years. The one I have is a pretty simple/dumb device - it doesn't recognize or care about the filesystem, so it will work reliably with pretty much everything. I've used it with FAT, NTFS, ext3, ext4, and reiserfs. I'm not sure if I've used it with xfs, but I might have. The only times I've had problems are when there was a problem with the disk (either the drive was bad or the file system was already corrupted).

There is one undocumented trick to using the device that I have. Many desktop drives, particular older ones, need to start up before the device is plugged in, otherwise either the adapter or drive can end up in a state where they are not communicating. Basically, with the device I have, I plug the adapter and power cable in to the disk drive. I turn on the power to the drive and wait for it to spin up. When in doubt, I'll wait for 30 seconds to 1 minute. Then I finally plug the USB cable into the computer. Wait another 15 seconds, or so, for the computer to recognize the adapter and drive. At that point you should be able to mount the disk.

If that doesn't work, see if the drive and adapter will work in another computer, or if the adapter works with another drive.

Lirey. Your sugestion worked. hook up he power, start the pc, wait for spinup, plug in USB. Good to go. Thanks.
