Greetings,

I have a toshiba SCSI Disk from my old Dell laptop. Nothing was wrong with it when removed from the laptop 3 years ago. I recently purchased a SATA to USB adapter in order to view and retrieve some old videos from it (using my present Dell which has a Samsung SSD)

The first time I hooked the Toshiba Disk up to my current laptop it appeared in Disk Management but I couldnt access anything. However in subsequent attempts I cannot get it to show up there although it appears as Drive D: in windows and it is showing correctly in Device Manager. So it appears the communication with Windows is Ok (although I can not populate information about the disk properties from either place)

Any data/HDD recovery software must find the disk in disk management so I cant get anywhere with those. When plugged in, windows gives the usb connected sound alert and the HDD light turns on and I can hear the HDD spinning. The eject option is there in the system tray but no drive is assigned to the external HDD (and I can’t pull up this info in Properties). Plugging the old drive in really slows up everything else on my computer. All kinds of things start going amiss when the drive is hooked up. Unplugging the disk I get the message “a device which does not exist was specified” and everything speeds back up to normal. Also, windbg preview created a partition and I have a bunch of MDMP files (I guess from the drive) - on my local disk C:. Windbg is too much for my current competence and I have no desire to debug anything. I just want to retrieve some old videos.

I’m pretty basic skill level with this but I follow instructions well. Can anyone help me access my old drive?
