Question about Plextor PX-EH40L (PXEH40LT3UK) 400 GB

Open Question

I have a plextor PX-EH40L NAS drive. It was working just perfectly until I screwed up. I was having to reload software on a computer of mine so I was copying data to the NAS drive. I had a file on the drive I did not need so I opted to delete of the NAS drive. I did not note that all the files on my drive were highlighted until they started disappearing. I quickly unplugged the drive. I tried to find something to recover the deleted file to no avail. I was unable to get any of the file recovery programs to connect to anything other than local drives. So SMART ME took the drive out of the case and connected my Ultra USB to IDE adapter cable to the drive and found it had 3 partitions once I configured the pins on the back of drive to 16 heads master |::| then I connected to ParetoLogic Data Recovery software and was attempting to recover the files. The software would find about 500 files and then seem to stick. I gave up on the recovery and placed drive back in case and now it will not connect to the network. Now I am not sure what the correct pin config is. I know I should leave stuff alone but I always think I can fix it.

Hi there,
The reason why they are unrecognized is because the hard drive aside from having a bad network card has a bad File Sytem.
Please try another computer to check if the file system of those partitions will be recognized. If not you may want to use this software called recuva and recover as much files as you could. Although it doesn't guarantee 100% file recovery I'm sure it will be able to recover the files that are still readable.
There's the link where to download the software.
Hope this helps!

My plextor digital video converter px-av100u cant work in my laptop. in my laptop i have windows 7 operating system. please tell me how can i use my capture card.

I could not download a Plextor driver that works w Windows 7. I purchased a Gigaware Video Converter from Radio Shack for $49 which works great with Windows 7. Software also converts video captures into mpeg files so saves time converting from codex.

The plextor dvdr px 708a stopped working


Thanks for coming to FixYa, The problem you have is either a well documented software problem, corrupted plextor software or a failing drive.

Click the below link, then scroll down and click the "Fix It" button. Follow the onscreen instructions, restart when it's done and see if your drive re-appears. If it does, you're done, if it doesn't work then try re-installing the plextor software. Again if that doesn't work then your drive is most likely failed and you should replace it.

Hope this helps FixYa,

With Windows Vista?

Unfortunately, Plextor has discontinued the unit and has no plans of EVER releasing VISTA drivers.They have never answered my e-mails about this problem...and, quite simply, us owners are screwed if we are limited to VISTA. I keep my old P4 2.8 hooked up for the occasional VHS to DVD transfer. Plextor's customer service is, was, and ever shall be, pathetic. Sorry for the bad news.

Is the drive appearing in My computer with a drive letter?

If it isn't:
1. click Start, point to Run, type diskmgmt.msc, and then click OK
2. If you see your drive listed without a letter, right click on it and assign it a new drive letter
