In a short run is fine, but in a long run due to load on hard drive it will wear off significantly faster and eventually fail earlier.
You get another memory storage device, such as an external hard drive, and you copy everything on your hard drive onto the external hard drive, and keep it safe. That way, if your hard drive crashes, then you can take it out, and plug your external hard drive in, and work from that.
DVD is a perfectly safe way to store media,no need to clutter your hard drive.
Before you send your computer to the electronics graveyard, remove the hard drive. If the computer still functions, you can erase the hard drive.
It is perfectly safe as it will use your internal memory (HDD) to emulate a Disk Drive(s) in order to run the CD(DVD)-image file from your hard drive.
If a hard drive is external to computer then it is easy to move it between computers if required or take it away for safe keeping. If it has a good had drive enclosure then it is more protected from the elements or from accidental damage.
The normal hard disk temperature is 25C - 45C. Having slightly higher or lower HDD temperature is still safe, but it will potentially reduce your hard drive lifespan and reliability.
Maybe a little less stability and comfort in riding, but it is sure hard on your tires.
Backup
Click the Hard drive, then choose the "pen" drive, a message will show up, click yes, then another message swill appear, click,OK, then remove the "pen" drive
You can not make any physical repairs to the hard drive. If it is the problem then it must be replaced. Do you know for sure the hard drive is bad? Have you tried these troubleshooting steps to make sure the hard drive is bad? Try restoring the file system. I will attempt to repair damage files on the hard drive/ Try another hard drive if you have access to one. Remove the hard drive and then re-insert. Try to restore the system. Go to Safe Mode and select "Restore PS3 System". This will restore the default settings and re-format the hard drive. If you have tried these and that has not help then you will need to replace the hard drive. Hope this helps
SFC, Chkdsk, and Defrag
I would say so. A lot of people say it's really easy
