Is it my hard drive?

[Laurence mendes]

Hi im a singer songwriter for many decades, acoustic. I wish to complete and record foyright purposes around 150 new songs and poems. Yet my 2488 says HDD problem. Ive opened, checked and cleanef ribbons and connections, put it back together. No joy. How do I know if its the hard drive or not? If so where do I buy replacement, latest version. I missed buying an unused one on ebay for £17.20 sadly. L in Herefordshire
