Hard drive in USB enclosure gets "device descriptor read/64, error -71"


I have an IDE hard drive in a USB enclosure that I am attempting to connect to my laptop (which is running Slackware Linux 12.2, kernel 2.6.27.7). Other USB devices, including a USB flash drive, work fine when connected to the laptop.

But when I attempt to connect the hard drive in its enclosure, I get the following results from dmesg:
Code:

I found a few posts that referenced changing /sys/module/usbcore/parameters/old_scheme_first from "N" to "Y", but neither setting fixes the problem.

I also found a post here that suggested that the problem might be related to CONFIG_USB_SUSPEND. I was unable to create the file /sys/module/usbcore/parameters/autosuspend, it was not permitted even as root. Since lsmod shows no usb-related modules in the list, I assume they are compiled into the kernel, so I attempted to achieve the same effect by passing the options usbcore.autosuspend=-1 or usbcore.autosuspend=0 to the kernel at boot time (neither fixed it).

I have also tried using a different USB cable to connect to the enclosure (also did not work).

...any suggestions how to get this working would be greatly appreciated.

Are you sure the drive, and its enclosure itself, is in working order?

I'd take them and put them on a Windows system (for example) and see if they work there.

The error messages you posted might also indicate that the drive is formatted with an unknown filesystem. Do you what is formatted as? NTFS?

If it IS, in fact, formatted NTFS, do you know if your kernel has NTFS support? If you are using NTFS-3G (a 100% working Linux module for working with NTFS partitions under recent kernels) is it loaded and working?

I've also seen this sometimes if, for example, you are dual-booting and Windows crashes, and you then directly boot into Linux, NTFS-3G won't mount your WIndows partitions, complaining that some of them aren't "clean". I. e. did you loose power on that drive recently while it was connected to another system?

Did the drive fall or get a whack recently?
