There are a number of causes of this kind of error and they include:

• USB Port problem – a weak or bad USB port power supply may affect or damage the hard drive. When USB port is in bad condition, the hard drive might not work. Also, the USB is the link between a computer and an external hard drive and once it is not functional, the hard drive might be damaged.
• Improper removal of the hard drive – unplugging the hard drive from the computer directly without following the safe removal process damages the hard drive hence the cause of the error above. Safety removal of the hard drives is very important.
• Bad sectors on the external hard drive – one bad sector in an external hard drive might make the entire partition inaccessible. These bad sectors might damage the whole drive.
• File system corruption – the parameter is incorrect error is mostly caused by this reason. Managing the data on the partition is the role of file system and once it is corrupted, it is not able to perform its role

Step 2 Right click ‘This PC’ then ‘Manage’ then ‘Disk Management’

Step 3 Right click the RAW or corrupted drive and select ‘format’ then click ‘OK’

Step 4 Set the volume level, file system format then check the ‘perform quick format’ option. Once done, click ‘OK’ to format.

Solution 2: Run ‘chkdsk /f /r’

This solution is able to work on bad sectors on the drive, lost clusters, file system and directory errors and cross-linked files.

Step 1 Click ‘start’ then ‘all programs’ and ‘accessories’. After you are done right click ‘command prompt’ and select ‘run as administrator’ then click ‘allow’ if you are prompted to enter as an administrator

Step 2 Type command line ‘chkdsk/f/rX’ in the command prompt then click ‘enter’

Here are a number of things to try if you are having problems updating your iPod classic, or if your computer freezes when it is connected.

Recover media from a manually managed iPod

What follows are tips for restoring your iPod, but if it is the only location currently hosting some of your media then the first task is to try to extract it. See the user tip Recovering your iTunes library from your iPod or iOS device for some recovery tools. Most third party tools will probably require the device to have a functioning library however the method given in Recover media from an iPod should work as long as the device still shows up in Windows Explorer or Finder.

Check your iPod with Diagnostics Mode

It is possible that your iPod's hard drive has started to fail. Take your iPod and place your right thumb on the centre SELECT button and your left on the top MENU button. Press down both thumbs for about 6 seconds until your iPod reboots. Immediately move your left thumb around to the rewind button |<< on the left and hold this down together with SELECT for a further 6 seconds. Your iPod should now switch into Diagnostic Boot mode. Press MENU for Manual Test, then select IO > HardDrive > HDSMARTData to reveal your stats. For comparison here are mine taken when my 6th Generation Classic was about 2 years old:

Retracts: 889

Reallocs: 12

Pending Sectors: 0

PowerOn Hours: 2202

Start/Stops: 894

Temp: Current 24c

Temp: Min 10c

Temp: Max 50c

Take a note of your results. When finished press MENU+SELECT for 6 seconds to reset the iPod again.

With modern disk drives sectors are no longer marked bad by a disk scan, if the SMART firmware detects a sector it has trouble accessing it will attempt to invisibly reallocate it to a spare area of the disk.

Note that I've only 12 remapped sectors and none pending. To help explain what the numbers mean here is an extract from the Wikipedia S.M.A.R.T. article:

Reallocated Sectors Count

Count of reallocated sectors. When the hard drive finds a read/write/verification error, it marks this sector as 'reallocated' and transfers data to a special reserved area (spare area). This process is also known as remapping, and 'reallocated' sectors are called remaps. This is why, on modern hard disks, 'bad blocks' cannot be found while testing the surface – all bad blocks are hidden in reallocated sectors. However, as the number of reallocated sectors increases, the read/write speed tends to decrease. The raw value normally represents a count of the number of bad sectors that have been found and remapped. Thus, the higher the attribute value, the more sectors the drive has had to reallocate.

Pending Sector Count

Number of 'unstable' sectors (waiting to be remapped, because of read errors). If an unstable sector is subsequently written or read successfully, this value is decreased and the sector is not remapped. Read errors on a sector will not remap the sector (since it might be readable later); instead, the drive firmware remembers that the sector needs to be remapped, and remaps it the next time it's written.

Large numbers of Reallocs or Pending Sectors (several thousand in the case of a classic) would suggest your drive is failing and that you may need to repair or replace your iPod. Check your stats after another attempt to update your iPod. If the numbers increase that again points to hard drive failure. While it won't be good news at least you'll know it isn't some random software problem and you can decide what to do next.

Check iPod hard-drive for errors

Assuming the diagnostics give the drive a clean bill of health it may still be worth checking the drive for logical file system errors.

Hold MENU+SELECT on the iPod for about 6 seconds until it resets, then switch to PLAY+SELECT as soon as the Apple logo appears, again for about 6 seconds to put the machine in disk mode. Open iTunes and in the Devices tab of the preferences menu check Prevent iPods, iPhones, and iPads from syncing automatically. Now connect your iPod to the computer, wait until it connects, then close iTunes.

Windows: Browse My Computer and right-click on the drive for the iPod, click Properties, then click Tools. Under Error-checking, click Check Now. Under Check disk options, select Scan for and attempt recovery of bad sectors (Optional - takes ages but a good idea if you've reason to suspect physical damage). Click Start.

Mac: Run Disk Utility / Repair Disk for the equivalent process.

This should find and correct any errors in the logical & physical structures of your iPod's hard drive. Once these have been fixed you can reset the iPod (hold MENU+SELECT) and should stand a better chance of a successful restore. It might also pay to check the status of the source drive containing your media, particularly if no errors were found on the iPod.

DFU Restore

If the device still won't restore normally try this method. Connect the device to the USB cable, press MENU+SELECT like a standard reset but keep holding for 12 seconds. The device should reboot as normal and then the screen should go blank. Now open iTunes and try to restore again.

Reformat Drive

If all else fails try Erase your iPod - The Super Fix for most iPod Problems. Basically a low level format of the iPod’s hard drive to get around whatever problems are stopping iTunes from restoring it properly.

Another approach for a Windows formatted iPod is to get a Mac owning friend to restore the device and then return it to you for restoring again on Windows, or have a Mac formatted iPod restored by a Windows user and then restore it again on a Mac.

Break up large transfers

Once you've restored your iPod don't rush to dump all the data back exactly as it was before. I have found that lots of large or complex smart playlists can sometimes trigger constant reboots or dumping of the iPod's library. In addition, larger transfers can fail leaving data in an inconsistent state. Try this technique for populating the iPod in stages.

In iTunes select the menu item File... New Smart Playlist. Change the first drop-down box to Playlist, the next to is and the next to Music or whatever playlist holds the bulk of the content you want on your device. Tick against Limit to, type in say 10, then change the drop-down to GB, and set the last drop-down to artist. When you click OK you can enter a name for the playlist, e.g. Transfer.

Now sync this playlist to your iPod rather than your entire library. When the sync is complete modify the rule (File... Edit playlist) to increase the size by your chosen amount, then sync and repeat. You can experiment with different size increments, if it doesn't work just choose something a bit smaller until it works each time. Before long you should have all the music that you want synced added to your device. Once that's done you can move on to other media such as podcasts, videos, photos, additional playlists, etc.

iPod click wheel games

iTunes 12.7 introduced changes to iTunes which have removed the management features for iPod click wheel games. They can neither be added to an iPod nor transferred from it. Should you want that facility you may need to temporarily install a copy of iTunes 12.6.5.3 which can be obtained from Deploy apps in a business environment with iTunes - Apple Support. If needs be you can make a separate library to work with this build and iPod games or iOS apps, then reinstall the current version of iTunes and reconnect to your regular library when ready.
