Well Sony dumped sonicstage too. Try using Windows Media Player make sure you have version 11 though other wise it won't recognize. I have a walkman but it is a downgrade from yours the NWZ-S615F.

Bad news - if you tried multiple pc's and it still failed, then your player is done.

Make sure you:
reset the player
upgraded the firmware
used the recovery tool
called Sony to be sure
last ditch effort:
Try this: disconnect the player from the computer, turn it off, hold in the volume + button, and reconnect the player to the computer while holding the volume + button in. Keep holding the volume + button for an additional 5-50 seconds. Windows should eventually go into recovery mode and revive the player- it will pop up a window that says Found New Hardware.

I suggest that you uninstall and reinstall the USB Driver to resolve the issue.
Follow these steps to uninstall the driver and confirm the player is recognized properly.

  • This procedure must be performed while logged in as Administrator or to an account with Administrator rights.
  • If you are using the Windows® XP operating system, you must have Service Pack 2 or later installed.
  1. Click Start and then click Control Panel .
  2. In the Control Panel window, click Performance and Maintenance .
  3. In the Performance and Maintenance window, click System .
  4. In the System Properties window, click the Hardware tab.
  5. On the Hardware tab, under Device Manager , click the Device Manager button.
  6. In the Device Manager window, click the plus (+) sign in front of Disk drives .
  7. Click to select the Sony USB device .
  8. From the menu, click Action and then click Uninstall .
  9. In the Confirm Device Removal box, click OK .
  10. Disconnect the portable player from the computer.
  11. In the System Settings Change box, click Yes.
After that, restart the computer and reconnect the Player to resolve the issue. USB Drivers are generic to the Operating System and will reinstall automatically after restarting the computer. I hope it works.

Hi Karen_mar606,

To reinstall the Reader Software you can go to the link below:

If the issue still persist you may need to delete the registration folders for the reader and then reinstall again. I'm not sure which OS you have in your PC but you can find a way to delete these folders on the forum below:

Syncing Books to your Slick Er700-2 E reader

Hello, Everyone. Some of you might run into a few problems when trying to sync books to your Er700-2 E reader. this is the best way to get things rolling.

1. Borders is no longer in business and neither is the desktop app that comes with the Er700. Download the new desktop app here:

2. If you had a Borders account, follow the steps to migrate your old account into Kob's new library.

3. You will also need to download Adobe Digital Editions from
here is the link to downlaod a copy

You can now purchase books to add into your online library. But don't sync
the player with Kobo. use your new copy of adobe digital editions to add your ebooks into your Er700-2. Connect your Er700-2 to your PC. in ADE, you'll see an e reader icon. click and drag the ebooks from your ADE library into the E reader icon to sync your device.

safely eject the device and happy reading!!!!

Oh yeah, if by an chance that you get error messages, or your e reader crashes, there's a firmware update on the company's website. I advise you to backup your e reader before you continue because it'll erase it. you can always restore your e reader after the firmware update.

here's the link for the firmware update:

Every time i hook my prs350 reader into my computer it downloads all of my books again, how do i stop that happening.


Probably you are using the "Automatic Sync". To disable sync follow these steps:

1. Open the Reader Library and Connect your Reader
2. Double click on the word "READER" on the left panel
3. You will have the option "SYNC", click on it
4. On the right side you will have some checked boxes .... Uncheck them all

If you are unable to disable SYNC that way. Go to this link:

I "think" I have downloaded and paid for a book on my e-reader. Problem: i bought directly from Sony in Dec. And cannot find the instruction book. About a month ago I found instructions online but cannot...

You bought the book on the Reader Store and now it won't show on your reader? Is the book on your Reader Library (not the device itself, but the computer library)? If it is, drag it to the Reader icon on the Reader library and it should upload. If that doesn't work, try syncing the information, although I wouldn't recommend it because its a pain when you try to delete information. Good luck!

I installed library on pc last night & loaded some books on - everything ok but today there seems to be some kind of conflict because library seems to freeze and not recognise 300 when connected....

Try turning on the reader before connecting it to the computer, with the linrary not opened. Hopefully Reader Library will open automatically.

Also can try having the reader connected (and turned on) when you turn the computer on.
